    SAFEXPLAIN: Safe and Explainable Critical Embedded Systems Based on AI2023Ingår i: Proceedings -Design, Automation and Test in Europe, DATE, Institute of Electrical and Electronics Engineers Inc. , 2023Konferensbidrag (Refereegranskat)
    Abstract [en]

    Deep Learning (DL) techniques are at the heart of most future advanced software functions in Critical Autonomous AI-based Systems (CAIS), where they also represent a major competitive factor. Hence, the economic success of CAIS industries (e.g., automotive, space, railway) depends on their ability to design, implement, qualify, and certify DL-based software products under bounded effort/cost. However, there is a fundamental gap between Functional Safety (FUSA) requirements on CAIS and the nature of DL solutions. This gap stems from the development process of DL libraries and affects high-level safety concepts such as (1) explainability and traceability, (2) suitability for varying safety requirements, (3) FUSA-compliant implementations, and (4) real-time constraints. As a matter of fact, the data-dependent and stochastic nature of DL algorithms clashes with current FUSA practice, which instead builds on deterministic, verifiable, and pass/fail test-based software. The SAFEXPLAIN project tackles these challenges and targets by providing a flexible approach to allow the certification - hence adoption - of DL-based solutions in CAIS building on: (1) DL solutions that provide end-to-end traceability, with specific approaches to explain whether predictions can be trusted and strategies to reach (and prove) correct operation, in accordance to certification standards; (2) alternative and increasingly sophisticated design safety patterns for DL with varying criticality and fault tolerance requirements; (3) DL library implementations that adhere to safety requirements; and (4) computing platform configurations, to regain determinism, and probabilistic timing analyses, to handle the remaining non-determinism.

    Free open source communities sustainability: Does it make a difference in software quality?2024Ingår i: Empirical Software Engineering, ISSN 1382-3256, E-ISSN 1573-7616, Vol. 29, nr 5, artikel-id 114Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Context: Free and Open Source Software (FOSS) communities’ ability to stay viable and productive over time is pivotal for society as they maintain the building blocks that digital infrastructure, products, and services depend on. Sustainability may, however, be characterized from multiple aspects, and less is known how these aspects interplay and impact community outputs, and software quality specifically. Objective: This study, therefore, aims to empirically explore how the different aspects of FOSS sustainability impact software quality. Method: 16 sustainability metrics across four categories were sampled and applied to a set of 217 OSS projects sourced from the Apache Software Foundation Incubator program. The impact of a decline in the sustainability metrics was analyzed against eight software quality metrics using Bayesian data analysis, which incorporates probability distributions to represent the regression coefficients and intercepts. Results: Findings suggest that selected sustainability metrics do not significantly affect defect density or code coverage. However, a positive impact of community age was observed on specific code quality metrics, such as risk complexity, number of very large files, and code duplication percentage. Interestingly, findings show that even when communities are experiencing sustainability, certain code quality metrics are negatively impacted. Conclusion: Findings imply that code quality practices are not consistently linked to sustainability, and defect management and prevention may be prioritized over the former. Results suggest that growth, resulting in a more complex and large codebase, combined with a probable lack of understanding of code quality standards, may explain the degradation in certain aspects of code quality.

    Infrastrukturmodellering för storskalig introduktion av elflyg och flygtrafikledning (MODELflyg)2022Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    En generisk, flexibel simuleringsmodell utvecklas med syftet att kunna bidra till förståelse samt ge möjligheter att enkelt testa vad elektrifiering (batterielektriskt) av önskade flygtrafikflöden kan förväntas innebära i form av krav på laddinfrastruktur vid flygplatserna. Modellen utvecklas i programspråket Python och innehåller ett flertal olika tillvägagångsätt för att testa elektrifiering såväl baserat på inläsning av historiska flygtrafikdata, som skapande av nya, icke-existerande flygtrafikscheman för elflyg. Eftersom det i dagsläget inte finns några elflygplan i kommersiell linjetrafik, och således inte heller någon data eller statistik gällande dess prestanda eller egenskaper, så utvecklas en modell även för detta, vilken tillåter simulering av önskade flygförbindelser, och resulterar i erhållande av energiförbrukning och flygtid på dessa. Projektet utgår ifrån en elflygplansmodell som är parametersatt i enlighet med certifieringsnivå CS/FAR-23 (19 säten och maxvikt 8618 kg). Logiken i modellen är att följa den fullständiga rörelsekedjan för varje flygplansindivid under en given tidsperiod (typiskt ett dygn), där behovet av laddning för respektive flygplan på respektive flygplats i kedjan ges av vilken energinivå batteriet höll vid påbörjad flygning, hur mycket energi som förbrukades under flygningen, när flygplanet anländer till destination, samt när det behöver påbörja nästa flygning. Även in- och uttaxning på flygplatserna påverkar hur mycket tid som finns tillgänglig för laddning. En inbyggd laddningskurva begränsar hur snabbt det är praktiskt lämpligt för batteriet att laddas. Laddningskurvan definieras genom ett förhållande mellan C-rate (Charging-rate) och SoC (State-of-Charge). Dessutom kan laddare i sig begränsas till en viss maxeffekt och styr således hur snabbt energi kan levereras till flygplanets batterier. För att möjliggöra tillräcklig räckvidd förväntas elflygplanen ha relativt stora batterier som dessutom sannolikt ska laddas upp inom korta tidsintervall på flygplatserna (turnaround-tider). Därmed kan behovet av installerad effektkapacitet förväntas öka drastiskt på flygplatserna om flera elflygplan behöver ladda samtidigt. Projektet lägger därför lite extra vikt vid att utveckla smarta algoritmer för styrning av effektuttag över tid med ambitionen att lastbalansera och sänka effekttoppar vid simultan laddning. Till sist diskuterar projektet vilka implikationer elflyg kan medföra ur perspektivet flygtrafikledning, befintliga och framtida luftrumsstrukturer. Ett flertal fallstudier genomförs för att exemplifiera modelleringsprocessen och de resultat som användaren slutligen får. Projektet syftar inte till att skapa något färdigt kommersiellt verktyg, utan snarare en första version, samt lägga grunden för vidareutveckling av ett analysverktyg som är till nytta för flygplatser och andra aktörer inom flygbranschen nu, och i framtida forskning- och utvecklingssamarbeten.

    Infrastructure modeling for large-scale introduction of electric aviation2022Ingår i: 35th International Electric Vehicle Symposium and Exhibition (EVS35), 2022Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents the results of the MODELflyg research project funded by the Swedish Transport Administration to gain more knowledge about ground charging infrastructure demand for the electrification of air traffic. An integrated simulation model was developed including flight traffic data processing, modelling of battery electric aircraft performance, and charging simulations. Several different options are available to select specific air traffic flows of interest, including scheduling algorithms for electric aviation adapted timetables. Furthermore, a smart-charging algorithm was developed to lower peak power demand at each airport from simultaneous charging of multiple electric aircraft.

    Ruttbaserade simulerade trafikdata för högupplöst analys av tunga godstransporter på det svenska vägnätet2022Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Route-based simulated traffic data for high-resolution analysis of heavy goods transport on the Swedish road network In this report, a national database has been created regarding freight transport with heavy road vehicles. The primary purpose of the work is to serve as input for further analysis of what appropriate charging infrastructure planning and placement should look like given the knowledge of the transport work. It has thus been no ambition to give any recommendations in this report about, for example, expansion of charging infrastructure, but rather to collect and process information/data as well as develop methods and finally generate a data set that is useful and well representative of the traffic on the national road network. By the time of this publication, a dataset is available based on data from the Swedish Transport Administration’s Samgods-model with its simulations of transport connections based on transport demand between producer and consumer zones. In addition, all transport connections have been translated into routes (how trucks drive from A to B) on the road network, to enable analysis of electrification of/at specific road segments. Finally, the dataset has also been calibrated in various ways to better match statistics and actual measurements, as some major differences/deviations compared to some of them were identified. What the data set now consists of can be summarized as the number of truck movements and tons of goods that annually pass each road segment of the Swedish road network (and on some foreign roads). Furthermore, these totals can be easily divided into subsets and linked to specific routes, types of trucks (weight classes), origin, etcetera. Some shortcomings/limitations have been noticed during the production of this data set, such as the fact that the Samgods-model seems to miss a lot of transport in metropolitan areas, that the routing carried out by all flows is not completely perfect (which has partly to do with requests from OpenStreetMap), that the methods for generating new routes based on population density within municipalities are unlikely to be fully representative of where the transport is going, or that the data itself is based on a simulation model that tries to optimize which type of transport should be used to meet which demand. A couple of additional things may be worth clarifying: (1) The data only tells the number of transports or shipped goods between start and end nodes. Thus, there is no way to determine what the movement pattern of individual vehicle individuals looks like between routes, nor when in time each transport is performed. (2) The data only includes freight transport, and thus "misses" for example all passenger car traffic, which should also be seen as potential users of the charging infrastructure and thus be included in the calculations in the future. It would therefore be interesting to include these in some way in the next step.

    Guardian Angel: Using Lighting Drones to Improve Traffic Safety, Sense of Security, and Comfort for Cyclists2023Ingår i: Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics)Volume 14057 LNCS, Pages 209 - 223, Springer Science and Business Media Deutschland GmbH , 2023, Vol. 14057 LNCS, s. 209-223Konferensbidrag (Refereegranskat)
    Abstract [en]

    Active mobility, such as biking, faces a common challenge in Swedish municipalities due to the lack of adequate lighting during the dark winter months. Insufficient lighting infrastructure hinders individuals from choosing bicycles, despite the presence of well-maintained bike paths and a willingness to cycle. To address this issue, a project has been undertaken in the Swedish municipality of Skara for an alternative lighting solution using drones. A series of tests have been conducted based on drone prototypes developed for the selected bike paths. Participants were invited to cycle in darkness illuminated by drone lighting and share their mobility preferences and perception. This paper summarizes the users’ perception of drone lighting as an alternative to fixed lighting on bike paths, with a special focus on the impact on travel habits and the perceived sense of security and comfort. Most participants were regular cyclists who cited bad weather, time, and darkness as significant factors that deterred them from using bicycles more frequently, reducing their sense of security. With drone lighting, the participants appreciated the illumination’s moonlight-like quality and its ability to enhance their sense of security by illuminating the surroundings. On the technology side, they gave feedback on reducing the drone’s sound and addressing lighting stability issues. In summary, the test results showcase the potential of drone lighting as a viable alternative to traditional fixed lighting infrastructure, offering improved traffic safety, sense of security, and comfort. The results show the feasibility and effectiveness of this innovative approach, supporting transformation towards active and sustainable mobility, particularly in regions facing lighting challenges.

    Standardisation of Electric Road Systems: Report from workshop at FIRM192020Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Electric Road System (ERS) is a technology concept that has the potential to dramatically reduce the fossil fuel dependency in the transport system. ERS is defined by electric power transfer from the road to the vehicle while the vehicle is in motion, and could be achieved through different power transfer technologies from the road to the vehicle, such as rail, overhead line, and wireless solutions. The basic technologies for power transfer from the road to vehicles in motion have been developed through various international research projects. In recent years, ERS has moved from conceptual idea to real-world application in countries such as Sweden (2016 and 2018), the United States of America (California 2017), and Germany (2019). In addition, projects are being planned in Italy and China.

    National and international freight transports in Europe are usually determined by national and EU strategies and regulations. The success of ERS implementation, especially when it comes to a transnational roll-out, depends on using regulatory frameworks to identify areas where adaptation is needed.

    The work in the CollERS project has included a consideration of ERS in national and EU transport strategies. The present report relates to identification of areas where standards are missing or have to be adapted, as well a stakeholder dialogue (Germany, Sweden, Denmark and EU), e.g. by means of expert interviews at national and EU-level (industry, science, politics, and road administrations).

    Verktygslåda för bättre mobilitet på mindre orter – Utvecklingsprojekt med fem stationssamhällen i Småland2023Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Projektet "Stationssamhällen Småland: Verktygslåda för landsbygdsmobilitet" tog sikte på att möta utmaningar i relation till minskat bilresande i syfte att se till att Agenda 2030- målen kan uppnås samtidigt som tillgänglighet bibehålls. Fokus lades på mindre tätorter med tågstationer. Den övergripande målsättningen var att projektets resultat ska underlätta för kommuner att identifiera och implementera hållbara mobilitetslösningar som möter såväl invånares som näringslivets behov i den typen av samhällen. Projektet involverade fem småländska kommuner. Genom en fallstudiebaserad ansats, med metoder så som platsbesök, intervjuer och workshops med representanter för lokalsamhället och näringslivet kartlades behov, en färdplan för nya mobilitetstjänster togs fram och en verktygslåda som kommunerna kan använda för att själva planera och implementera dessa utvecklades. Projektet resulterade i en verktygslåda, presenterad som en Wiki-hemsida, som erbjuder en process för nulägesanalys, behovskartläggning, kunskapsuppbyggnad, idégenerering och implementering av mobilitetslösningar. Verktygslådan är avsedd att underlätta för andra kommuner att självständigt förbättra mobiliteten baserat på lokala behov. Insikter från projektet inkluderar betydelsen av brett stöd inom kommunen, näringslivets deltagande som en katalysator för förändring, och behovet av att utgå från specifika målgruppers behov. Projektet framhåller även vikten av mjuka åtgärder, kostnadseffektiva lösningar, och samarbete över kommungränser för att förbättra pendlingsresor. Genom att fokusera på marknadsföring av befintlig kollektivtrafik, optimering av kollektivtrafik, och olika former av samordnad mobilitet, inklusive cykling och samåkning, presenteras konkreta lösningar för ökad tillgänglighet och hållbar mobilitet på landsbygden.

    Slutrapport för EVIDIGVO2022Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Den här texten presenterar resultat från tre aktiviteter för kunskapsinsamling om implementering av digitala verktyg inom vård- och omsorg: en litteratursammanställning, en workshopserie i två delar och en enkätundersökning. Den primära målgruppen har varit verksamhetsutvecklare och projektledare i regioner och kommuner. Antalet svarande i enkätstudien var för lågt för att kunna dra några statistiska slutsatser, men resultatet kan, tillsammans med workshopserien, ändå användas för att identifiera områden där det verkar finnas utmaningar. Både litteratursammanställningen och enkätundersökningen pekar på ett behov av att utveckla strukturerade utvärderingsmodeller för implementering. Även under workshoppen diskuterades den bristande förmågan att ”samla in evidens under projektens gång”, och det fanns en önskan om att ett sådant arbetssätt skulle utvecklas. Enkäten och workshoppen pekar även på flera återkommande problem under implementeringsprojekts olika faser. I den inledande fasen efterfrågas bättre analyser och förankringsarbete. Analyser med användarfokus missas speciellt ofta, så som användarresa, hållbarhetsanalys och intressent- och behovsanalys. Även i andra ändan av processen, då system och arbetssätt ska avvecklas, finns utmaningar och förbättringsförslag, t.ex. saknas ofta beslut om utfasning av gamla lösningar, och ett förslag är att man redan när man skriver kontakt med en leverantör ska säkerställa att leverantören hjälper till med migrering vid utfasning. En annan genomgående problematik är osäkerhet, och ibland avsaknad, av roller, ansvar och kommunikation. Detta handlar om att man inte riktigt vet varför man ska göra saker, eller att verksamheten och personerna som ska göra förändringen inte är tillräckligt inblandade. Det kan också handla om att support och förvaltning inte är tillräckligt väl utvecklat, och om att man inte vet hur man kan samarbeta med leverantörer. Här identifieras även förändringsledning som ett viktigt verktyg för att underlätta en god implementering.

    Integration of Screen Printed Piezoelectric Sensors for Force Impact Sensing in Smart Multifunctional Glass Applications2022Ingår i: Advanced Engineering Materials, ISSN 1438-1656, E-ISSN 1527-2648, Vol. 24, nr 11, artikel-id 2200399Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Screen printed piezoelectric polyvinylidene fluoride?trifluoro ethylene (PVDF?TrFE)-based sensors laminated between glass panes in the temperature range 80?110?°C are presented. No degradation of the piezoelectric signals is observed for the sensors laminated at 110?°C, despite approaching the Curie temperature of the piezoelectric material. The piezoelectric sensors, here monitoring force impact in smart glass applications, are characterized by using a calibrated impact hammer system and standardized impact situations. Stand-alone piezoelectric sensors and piezoelectric sensors integrated on poly(methyl methacrylate) are also evaluated. The piezoelectric constants obtained from the measurements of the nonintegrated piezoelectric sensors are in good agreement with the literature. The piezoelectric sensor response is measured by using either physical electrical contacts between the piezoelectric sensors and the readout electronics, or wirelessly via both noncontact capacitive coupling and Bluetooth low-energy radio link. The developed sensor concept is finally demonstrated in smart window prototypes, in which integrated piezoelectric sensors are used to detect break-in attempts. Additionally, each prototype includes an electrochromic film to control the light transmittance of the window, a screen printed electrochromic display for status indications and wireless communication with an external server, and a holistic approach of hybrid printed electronic systems targeting smart multifunctional glass applications.

    SEBRA Sensor based awareness for bicyclists: FINAL REPORT2020Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The overall trend in Sweden is that the number of fatalities and severely injured in traffic is constantly decreasing. However, bicyclists are the group of road-users that often suffer the most severe injuries when involved in accidents.

    In this project we want to investigate if a radar mounted on bicycles can help bicycle riders to get better situational awareness and thereby avoid getting into dangerous situations.

    For active safety in vehicles, the state of art integrates radar-, lidar-, and camera-based sensors to create awareness for the vehicle and driver. To apply this kind of system on a bicycle would be unfeasible, since the cost would in some cases be as much as the entire bicycle. In this project we study and propose a low-cost sensor solution that improves traffic safety for bicycles that consist of only one of these sensors - the radar - it is the cheapest and most robust solution.

    The project first identified the most relevant use-cases and in conjunction to this, identify a business model that can make the safety system attractive for end-users. 

     Secondly, a radarbased safety system for bicycles is developed with both sensor and human interface.

    Finally,the system is evaluated in relevant traffic situations.

    The SEBRA project aims for the following research questions:

    - RQ1: What safety issues can be addressed by a radar-based safety system mounted onbicycles?

    - RQ2: What performance requirements (field-of-view, computational capacity, power consumption, etc.) should such a system fulfil?

    - RQ3: How should the interaction with the bicyclists be designed to give a high level of safety and user experience?

    - RQ4: How can incentives and business models be developed to create a viable utility device for bicycles?

    Within the scope of Open Research at AstaZero, we plan to simulate the selected scenarios from literature in the test track environment to finalize the answer for RQ1 and build answerfor RQ2. The tests also contribute initial insights for RQ3 answer.

    Exploring remote operation of heavy vehicles – findings from a simulator study2023Ingår i: IHSI 2023 Conference Proceedings, 2023Konferensbidrag (Refereegranskat)
    Abstract [en]

    Fully automated driving has posed more challenges than expected, and remote operation of heavy vehicles is increasingly getting attention. Therefore, human remote operators may have an essential role in compensating for the technological shortcomings in vehicle automation. This poses challenges in designing the work of human remote operators of automated heavy vehicles. This paper presents findings from a research project performed in collaboration between the RISE Research Institutes of Sweden and Scania. In the project, human-automation interaction requirements and challenges for remote operator work were explored through a simulator study. Before the study, three main operator tasks were defined: assessment, assistance, and remote driving. The simulation occurred in a transportation scenario where operators handled ten trucks driving on a public road and confined areas (transportation hub). Fifteen participants completed the study. The results provide examples and insights into classical automation-related challenges in a new context – the remote operation of heavy vehicles. Instances of challenges with situational awareness, out-of-the-loop, trust, and attention management were found and are discussed in relation to HMI design and requirements.

    Autonoma leveransfordon – vad är de för sorts fordon och har det någon betydelse?2022Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Autonomous delivery vehicles – what kind of vehicles are they and does it matter? The project GLAD – Goods deliveries during the last mile of self-driving vehicles explores how tomorrow's small autonomous delivery vehicles (ADV) could operate in the transport system. The goal of the GLAD project is to develop knowledge about the needs and challenges of such vehicles in Sweden before they are in real operation. In the project, there are several work packages that work with different challenges in relation to ADV. To explore these issues, the project has developed a prototype of an ADV, which is based on a vehicle which today is classified as a three-wheeled moped. But designed as an ADV it could be a different kind of vehicle. One result from one of the work packages in the project is that ADVs driving on public roads should maintain the same speed as other traffic to avoid critical traffic situations. This means that ADVs should be able to drive at a maximum speed of 70 km/h. Another requirement is that the ADVs should be able of carrying a load of 500 kg. These requirements are a conclusion from interviews with drivers of small manually driven delivery vehicles about how they experience today's traffic situations, from which type of road they use and how they use their vehicles. The purpose of this report is to identify obstacles and opportunities from a regulatory perspective to implement ADVs in Sweden in a safe way. Rules that may affect the development of ADVs are, for example, whether they are covered by the Machinery Directive or whether they should be type approved. Other rules concern license plates, motor liability insurance, where the vehicles may be driven and driving license requirements. The aim of the legislations is to create a safe vehicle to use. After a review of existing regulations, it is closest at hand that future ADVs, based on the requirements set in the project, are classified as a 4-wheel heavy motorcycle for the transport of goods. The vehicle also needs a type-approval. It can be argued that an ADV with that weight and speed will have a lot to prove from a safety perspective in a type-approval process and that a market introduction is therefore further away in time. If the speed requirements are lowered instead i.e., maximum of 30 km/h, it could be classified as a motor tool. The advantage of motor tools is that these must be CE-marked by the manufacturer, which in turn means that they have a shorter time to market because the process does not involve a type-approval agency.

    Legala hinder och möjligheter för obemannade off-peak leveranser2022Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    I projektet Hållbara & Integrerade urbana Transport System - HITS2024 har det bl.a. arbetats med att testa och demonstrera off-peak leveranser. Med off-peak leveranser avses förenklat leveranser som sker under de timmar på dygnet då det råder lågtrafik t.ex. nattetid. I projektet har HAVI levererat varor till en restaurang nattetid i Stock-holm. Detta har även demonstrerats i ett tidigare projekt kallat Eccentric. Skillnaden mellan de olika projekten är att i det äldre projektet fanns personal på plats i restau-rangen och tog emot varorna. I HITS2024 projektet fanns det inte någon personal på plats i restaurangen för att ta emot varorna. Båda projekten visar att det är praktiskt genomförbart att leverera varor off-peak och att det bidrar till en ökad transport-effektivitet. Jämfört med att leverera varor i rusningstid var tidsbesparingen ca 30 % för transpor-tören med off-peak leveranser i Eccentric projektet. Eccentric projektet visade även att effektivitetsvinsterna var ojämnt fördelade. Mottagaren (köparen) av varorna gjorde marginella effektivitetsvinster. För avsändaren (säljaren) redovisades inga effektivitets-vinster alls. I HITS2024 projektet ställde vi oss frågan - givet de stora effektivitets-vinster en transportör gör med off-peak leveranser - varför görs inte detta redan i stor skala? Kan det finnas något inom juridiken som hindrar utvecklingen av off-peak leve-ranser? Finns det rent av möjligheter inom juridiken som skulle kunna användas för att driva på utvecklingen mot fler off-peak leveranser? Syftet med den här rapporten är således att visa på legala hinder och möjligheter med (delvis) obemannade off-peak leveranser. Frågan kan bli än mer aktuell i en framtida värld med autonoma fordon som utför obemannade leveranser.

    Regelverk för datadelning inom citylogistik: nulägesanalys2022Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Almost all data sharing regulations have origins from the EU. At EU level, three trends can be identified for data sharing. The first trend is that data sharing more and more is regulated by legislation. Current regulations are being amended and many new regulations are underway within the EU. Data sharing legislations are thus in an expansive phase. There are also many reasons why the EU believes that a certain regulatory framework is needed, such as: • Information security: Historically, information security has generated a large amount of activity in the field of regulatory framework. This includes, for example, cyber security and preventing data breaches. • Human health: Human health is also a reason to regulate data sharing. Examples of regulations in this area are the GDPR and sharing of sensitive personal data. • Consumer protection: There are also regulations aimed at strengthening consumer protection and ensuring that, for example, digital services are safe for consumers to share data in. • A free and efficient internal market: For the EU, it is important to create an internal market for data sharing. Many regulations are aimed at ensuring that SMEs can compete with large companies. Example of legislation in this area is the Platform Regulation. • Increased innovation power: For the EU, it is also important to increase innovation capacity in the internal market. One way is to protect innovations through, for example, copyright and trade secrets rules. • Increased transparency and trust: To create an internal market, people and companies also need to feel safe sharing data. Example of legislation within this area is the proposed Data Governance Act. • Fundamental rights and freedoms: Finally, the EU is reassessing in many regulatory frameworks in terms of respect of fundamental human rights and freedoms. Examples of regulations in this area are the GDPR and the e-Privacy regulation. The EU is also working on developing a code on this theme. The code shall guide the future work on the develop of new legislation. The second trend is for the EU to encourage industry organizations to develop voluntary rules on data sharing (code of conduct) to accelerate the creation of an internal market for data sharing. An example of this is the Code of Conduct for sharing agricultural data in agreements. The Free Flow of non-personal data regulation would also like to see industry organizations develop principles for data sharing. The third trend is that the EU would like to see us all make more data publicly available or that we donate data, both from authorities and individuals (open data and altruism). Examples of this are the Open Data Directive and the forthcoming Data Governance Act. In this lies a conflict of interest between information security and open data that is not easy to solve. The challenge lies in the fact that each individual dataset itself does not have to reveal anything sensitive. However, if many datasets are added together, aggregated data can reveal too much. The EU is also interested in data sharing for certain sectors, of which vehicles and mobility is an area that is becoming more and more regulated in terms of data sharing. Here, a lot of new regulations are expected that will have a major impact on the sector, both in terms of vehicle development but also in terms of the development of new business models. The trend is towards vehicle manufacturers being increasingly forced to share data with authorities. When it comes to logistics, the pressure from new legislation about data sharing is not as clear. The existing legislation is more about the safe distribution of goods in a crisis or regarding sharing data from certain goods e.g., tobacco. What problems does the EU address in its mobility and vehicle regulations? • Human health: Compared to the general regulatory framework, there is a clear emphasis on human health and data sharing in the regulations. It is both about data sharing related to air quality but also road safety. • Consumer protection: There are also regulations aimed at strengthening consumer protection, e.g., for manufacturers to inform consumers about how much exhaust fumes a particular vehicle emits so that the consumer can make an informed choice based on this aspect between different manufacturers. • A free functioning efficient internal market: Examples of legislation in this area are the access of independent branded workshops to data from connected vehicles to increase competition. At EU level, there are several regulatory frameworks in the pipeline that will have a major impact on what we want to explore in our project. In the HITS2024 project, we want to explore and test efficient city logistics based on different vehicle concepts and logistics solutions. At EU level, a forthcoming e-Privacy Regulation is being discussed. The regulation will dictate how data from vehicles is allowed to be transfer to a cloud solution i.e., the connection as such. The e-Privacy Regulation is closely related to the GDPR, but there are also differences between these regulations. The GDPR accepts consent and balancing of interests to collect personal data while the e-Privacy Regulation only accepts consent (at the time of writing). The challenge for the automotive industry, for example, is that an autonomous vehicle can only collect personal data based on balancing interests because it is not doable to work with consent. However, if the e-Privacy Regulation in its current state is approved, the data will not be allowed to leave the vehicle because there is no consent. Another challenge is the upcoming AI Act. The AI Act distinguishes between technologies that already have an international regulatory framework for, e.g., type approval of a truck and technology where only the EU regulates the issue, e.g., machines. But a vehicle consists of many different “parts” and not all parts are type approved. How do you fit different technologies and different legislation together in an autonomous truck? In the logistics area, the upcoming Data Act can be of great importance as it will be about data sharing between companies. Until now, coordination between different data regulations has not always been optimal. The same phenomenon has been regulated in different regulations. There is a risk that different regulations in the future will find it difficult to co-exist with each other. How will, for example, GDPR, e-Privacy regulation and Data Act work together in a vehicle and logistics context? Developments in this area need to be followed.

    Transportdispenser: Analys av nutid och förslag på framtid2021Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Some transports considered too wide, too heavy, or too long to be driven on public roads must nevertheless be allowed to take place because of their societal importance. Such transports are granted a formal exception to the traffic rules. In this project, together with industry and national and local authorities we have analysed this process and submitted several proposals for improvement measures for consideration. The focus has been on increased digitalisation and improved legal processes. The analysis is based on interviews with municipal administrators, transporters and clients and representatives from Sweden's municipalities and regions, the Swedish Transport Administration, the Swedish Transport Agency, and the Swedish Police Authority. The interviews show substantial differences between how the Swedish Transport Administration and municipalities work with exemptions. Based on our analysis, we propose several individual measures as well as three design scenarios suggesting future opportunities for an improved process.

    Fordonsdata till allmänhetens nytta - geofencing och affärsmodeller2021Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Fordonsdata kan i framtiden vara till stor nytta för myndigheter på olika sätt. Än så länge samlar myndigheter in fordonsdata i begränsad omfattning. Det kan t.ex. handla om att genom offentlig upphandling pröva nya sätt för att kontrollera kvaliteten på utförd snöröjning. Trots att det finns ett intresse från både privata och offentliga aktörer att genomföra affärer kring fordonsdata är det ändå svårt för marknaden att ta fart. 

    Frågan om hur fordonsdata kan kommersialiseras med offentliga aktörer som köpare har därför undersökts inom Drive Sweden Policy Lab i samarbete med CeViss-projektet (Cloud enhanced cooperative traffic safety using vehicle sensor data). CeViss-projektet har undersökt smarta kameror och hur de bl.a. kan användas för att varna andra förare för vilda djur vid vägen eller informera SOS Alarm om hur det ser ut vid en olycksplats. 

    Förutsättningarna för lyckad kommersialisering kan sammanfattas under tre rubriker - affären, tekniken och juridiken. Vi ser att affären ligger i förmåga att erbjuda aggregerade data där olika datamängder korsbefruktas och därmed skapar ett större värde än de ingående datamängderna besitter var för sig. Kommersiella aktörer pekar på att rollen att aggregera data, eller förädla den, är mest intressant, eftersom det innebär en möjlighet att utveckla tjänster. En sådan tjänst förutsätter tillgång till en säker uppkoppling och överföring. Det är också resurskrävande att förädla data och styra rätt överföring, liksom att se över, anpassa och ta fram avtal som gör korsbefruktning av data och överföring av rätt data juridiskt möjlig. Här spelar individens integritet kontra samhällets behov av data en stor roll. Det är inte heller klart vilket behov aktörer inom olika samhällssektorer har av fordonsdata, samt hur dessa kommer att få tag i fordonsdata. 

    Utmaningen för industrin ligger i att våga lita på att det finns en hållbar affär med myndigheten i längden, dvs. att det finns en tillräckligt stor betalningsvilja från samhällets sida även när data anses samhällskritisk viktigt. För att främja kommersialisering är det bra att börja med ett specifikt utvalt område för att utarbeta processer, avtal, tekniklösningar, affärs-modeller och så vidare. 

    Geofencing hade kunnat vara en möjlighet att skapa de avgränsningar som behövs för en första affär, samtidigt som det skulle skapa tydlighet om var och när data samlas in från fordon. En sådan avgränsning hade också kunnat tjäna som en regulatorisk sandlåda för att utvärdera möjligheten till avtal som är hållbara över tid, det vill säga där det är rimligt att inom vissa gränser använda data på nya sätt eller för nya syften. 

    Rapporten avslutas med en sammanställning av geofencing och datadelning ur ett juridiskt perspektiv samt en beskrivning av Drive Sweden Policy Lab.

    RISE Policylabb – de första fem åren2023Rapport (Övrigt vetenskapligt)
    Abstract [en]

    In this report, we have compiled our learnings and experiences of working with Policy Lab. Policy Labs have come about as an answer to the question "Can you work with policy and regulatory development in a better way than today?". Our answer to the question is a yes. Our hope with the report is that others will become interested and start their own Policy Lab. Abroad, there are many Policy Labs, but in Sweden there are only a few, which is why we believe there is room for more. There is not a given way to work with Policy Labs once and for all, but each Policy Lab is unique based on its context. Sweden's innovation agency Vinnova defines Policy Labs as follows: "Policy Labs can be explained as a group of actors with different competencies who want to develop a regulatory framework. In the Policy Lab, they use a set of user-centric methods and competencies to test, experiment, and learn in policy development."1 In our Policy Lab, we have worked in various research projects to: 1. analyse challenges/problems that arise between innovations, technology, market, and regulations, 2. develop one or more workable solutions and 3. interact with relevant actors to determine the next steps. What distinguishes our Policy Lab is that we never “own” the issue or solution. We must therefore always work with other actors who can take the results further. Our goal is to enable and skill people. This means that for us it is important to work concretely with real problems and needs owners and preferably test different solutions. We focus on the here and now perspective and not on what the future will look like in 10 years. It is about taking the next step forward towards the future, not creating the best rule, but instead creating the next rule. We also work consistently agile and use design as a method for problem solving. This means that the way we organize our work in the Policy Lab is circular and not linear. When it comes to using design as a method for problem solving, we use the concepts of "design thinking" and "double diamond". For us, it is also important that the members of the Policy Lab have different backgrounds and skills depending on what is needed in the individual project....

    Self-certification of Autonomous Buses2021Rapport (Övrigt vetenskapligt)
    Abstract [en]

    It will still be a few years before we will have autonomous buses driving city streets and squares without drivers. On the other hand, it should be possible to have autonomous buses in a depot at an early stage in order to ensure more efficient maintenance of the vehicles when they are not in service, while at the same time learning how to be part of future operations. Such buses would be type-approved for manual traffic (SAE level 0-2), but not approved for autonomous road operation (SAE level 4-5). During the span of a single day, the bus will therefore alternate between the regulations for enclosed (fenced depot) and non-enclosed (road) areas, between being autonomous and not autonomous.

    The bus, which was previously a legal “static whole”, will now instead be tested based on two regulations depending on the environment it is in at any given time and level of autonomy. This is a completely new situation: that a bus is “dynamically divisible” from a regulatory perspective, which has significance in terms of who shall decide whether the vehicle is safe to use in a certain environment.

    After analysing the challenges based on existing regulations, interviewing relevant authorities, arranging workshops with various stakeholders and meetings with experts in certification, our conclusion is that, in order to be considered safe in autonomous mode within the depot, the bus should be self-certified by means of CE marking according to the Machinery Directive1. This is the authors’ conclusion and not necessarily representative of the other parties involved in the project.

    We predict that we will see more self-certification of autonomous vehicles in the future. Partly because there are such large international markets working in this way, such as in North America, and partly because it enables faster market introduction of dynamic vehicle concepts. With “dynamic vehicle concept” we mean vehicles that gain new areas of application by replacing the chassis or changing software settings and are thus converted from a bus to a truck or from a car to quadricycle. Maybe even several times a day.

    Self-certification, however, will also increase the need for standardisation, both for processes and products. Processes may involve how a vehicle can be certified, particularly how the risk analysis should be carried out. In terms of products, standardised descriptions of the technology’s function will facilitate proprietary self-certification since operators know how to describe their own products, including how their certification should be structured based on the constituent certified components. Current regulations will also need to be updated if more vehicles are to be self-certified, such as the Machinery Directive.

    Lastly, we would like to communicate the method used to reach our conclusions. The project has been carried out as a Policy Lab where we have brought together various stakeholders around a common challenge. This has enabled us to concretise both the challenge of autonomous vehicles within the enclosed area and our conclusions. The  method selected has also given relevant authorities the opportunity to familiarise themselves with how they should relate to tomorrow’s technology without having to present a view on how they will relate to a specific test or vehicle. In this way, Swedish authorities will be ready to adopt technical innovations once they are introduced to the market.

    This report is structured so that Section 2 describes the current regulatory framework, particularly in terms of the distinction between the Machinery Directive and vehicle type-approval. Section 3 uses specific examples to describe business operations pertaining to autonomous buses in a depot. Section 4 presents the authors’ conclusions based on how the regulations relate to the specific details obtained from the depot pilot. Section 5 presents the full picture by relating our conclusions to what is happening internationally and how the national ordinance on autonomous vehicle trials on roads corresponds to international trends. Lastly, in Section 6, we provide a summary of what we consider to be the most important issues for which further work should be carried out.

    Självcertifiering av autonoma bussar2021Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Det kommer att dröja några år innan vi har autonoma bussar som utan förare kör runt på stadens gator och torg. Däremot borde det tidigt gå att ha autonoma bussar i en depå för att få ett effektivare underhåll av fordonen när de inte är i tjänst, samtidigt som man lär sig hur de ska ingå i den framtida verksamheten. Sådana bussar skulle vara typgodkända för vägtrafik med manuell förare (SAE-nivå 0-2), men inte godkända för autonom drift på väg (SAE-nivå 4 eller 5). Under ett och samma dygn kommer bussen därför att ”hoppa” mellan regelverken för inhägnat område (depå) respektive inte inhägnat område (väg), mellan att vara autonom och inte autonom.Bussen, som tidigare var en juridisk ”statisk helhet”, kommer nu istället att prövas utifrån två regelverk beroende på vilken miljö den befinner sig i och på graden av automation. Detta är en helt ny situation, att en buss blir ”dynamiskt delbar” ur ett regelverksperspektiv, vilket i sin tur får konsekvenser för vem som ska bestämma att fordonet är säkert att använda i en viss miljö.Efter att ha analyserat utmaningen utifrån existerande regelverk, intervjuat berörda myndigheter, anordnat workshops med olika intressenter och arbetsmöten med experter inom certifiering är vår slutsats att bussen ska självcertifieras genom CE-märkning utifrån maskindirektivet för att anses säker i autonomt läge inom depån. Detta är författarnas slutsats och den är inte nödvändigtvis representativ för de andra parter som varit med i arbetet.Vi förutspår att vi kommer att få se mer självcertifiering av autonoma fordon i framtiden. Dels för att det är så den nordamerikanska marknaden arbetar, dels för att det möjliggör en snabbare marknadsintroduktion av dynamiska fordonskoncept. Med dynamiska fordonskoncept syftar vi på fordon som får ett nytt användningsområde genom att byta chassit eller ändra mjukvaruinställningar och därmed går från att vara buss till lastbil eller från personbil till mopedbil. Kanske till och med flera gånger om dagen.Med mer självcertifiering kommer också behovet av standardisering öka, både för processer och produkter. När det gäller processer kan det röra sig om hur man certifierar ett fordon, framförallt hur man gör riskanalysen. För produkter kommer standardiserade beskrivningar av teknikens funktionalitet underlätta den egna självcertifieringen då man vet hur man ska beskriva sin produkt, men också hur man kan bygga sin certifiering utifrån de ingående certifierade komponenterna. Även dagens regelverk kommer behöva uppdateras om fler fordon kan självcertifieras.Avslutningsvis vill vi lyfta den använda metoden bakom slutsatserna. Projektet har genomförts som ett Policy Lab där vi samlat olika aktörer runt en gemensam utmaning. På så sätt har vi förankrat både utmaningen kring autonoma fordon inom inhägnat område och våra slutsatser i konkreta detaljer. Valet av metod har också gett relevanta myndigheter möjlighet att sätta sig in i hur de bör förhålla sig till morgondagens teknik utan att behöva ge ett förhandsbesked om hur de kommer att förhålla sig till ett specifikt fordon eller försök. På så sätt är svenska myndigheter redo att ta sig an tekniska innovationer när de väl introduceras på marknaden.Den här rapporten är strukturerad så att avsnitt 2 redogör för de aktuella regelverken, framförallt gällande distinktionen mellan maskindirektivet och typgodkännande av fordon. I avsnitt 3 redogör vi för affären för autonoma bussar i en depå med konkreta exempel. Avsnitt 4 innehåller författarnas slutsatser utifrån hur regelverken förhåller sig till de konkreta detaljerna som fås från depå-piloten. Den större bilden ges i avsnitt 5 genom att relatera våra slutsatser till vad som händer internationellt och hur den nationella försöksförordningen för autonoma fordon på väg motsvarar de internationella trenderna. Slutligen sammanfattar vi i avsnitt 6 med en resumé och de viktigaste frågorna enligt vår syn att arbeta vidare med.

    Challenges and opportunities with the EU Taxonomy Regulation– with focus on chemical safety and usage in complex products2023Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The use of Policy Lab processes has been growing in Sweden and other countries to accelerate the adaptation of regulations to emerging technologies. Policy Lab facilitates active collaboration between relevant authorities, companies, and stakeholders through interactive and iterative methods based on Design Thinking principles. This approach bridges the gap between the legislative domain responsible for developing regulatory frameworks and the innovative companies that create solutions for emerging markets using new technologies and opportunities. In our study, we applied Policy Lab processes to the EU Taxonomy Regulation to identify challenges and opportunities related to chemical safety and usage for manufacturers of complex products. The EU Taxonomy Regulation, along with its delegated acts, represent a serious effort to establish standardized sustainability reporting within EU. However, it is still in its early stages and lacks maturity. Moreover, certain ambiguities within the regulation currently prevent a comprehensive comparison of companies due to the development of other legislations. Addressing these gaps depends on the future development of, for example, REACH. Our conclusion is that the EU Taxonomy Regulation is part of a larger “movement” that reflects the policymakers’ intentions. This intention also includes increased data sharing at a significantly different level compared to current practices. In the long run, the shift will enable authorities to access the data and develop new legislations. Our specific focus was on the objective of pollution prevention and control regarding the use and presence of hazardous substances listed in Appendix C of the EU Taxonomy Regulation. According to Appendix C, activities must not lead to the manufacture, placing on the market or use of listed substances, whether on their own, in mixture or in articles. Regarding listed substances, reference is made to existing EU legislation that regulates hazardous substances within the EU. The most challenging aspect in Appendix C is point (g), which aims to identify substances, whether alone, in mixtures, or in articles, that meet the criteria set out in Article 57 of REACH but are not yet included in the Candidate list. Our workshops, interviews, and literature review confirmed that the main challenge in meeting the criteria of Appendix C, specifically point (g) is the need to enhance transparency and traceability throughout supply chains. Overcoming these challenges requires addressing barriers, such as the lack of a harmonized regulatory framework across the value chain, the need for faster identification and restriction of hazardous substances, and the reinforcement of stronger enforcement measures. The enabling of full declaration of the hazardous properties and functions of the substances, while considering the balance between information disclosure and protecting trade secrets, would reduce the need for extensive tracking of substance of very high concern along the value chain. To improve communication along the value chain and identify data gaps while protecting trade secrets, workshop participants have proposed the use of a user-friendly interface based on traffic light scenario. This interface would serve as a filter mechanism, allowing product manufacturers to establish specific criteria for material suppliers to respond to. The objective is to enhance communication, establish criteria, and effectively identify data gaps. While the SCIP database ensures accessibility of information on articles containing substances from the Candidate List above 0.1 w/w%, it is limited to hazardous substances on that list. This means that hazardous substances not listed in the Candidate List may not be covered by the database. The EU Commission has proposed the implementation of a digital product passport to enhance information sharing about products and their supply chain, including substances of concern. Our study is conducted under the Mistra SafeChem program, where screening tools for hazard and exposure assessment of substances are currently being developed. These tools aim to provide screening data for direct decision-making based on the Defined Approach (DA). These screening tools have the potential to contribute to filling data gaps during the early design phases of complex products, particularly when screening for multiple material alternatives.

    Public Procurement and Geofencing – lessons learned from a pilot with geofencing of service trips2024Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The city of Gothenburg public procured geofencing technology and did a pilot during fall 2022 with geofenced service trips vehicles (retrofitted). This report investigates the challenges and opportunities associated with procuring geofencing technology, addressing aspects such as needs, market analysis, risk, alternative solutions, legislative framework, and much more based on lessons learned from the pilot. Geofencing, defined as the creation of virtual boundaries to monitor, inform, and control traffic using electronic communication technologies or predefined boundaries within vehicles, lacks standardization and comprises various technical solutions. Its functionality depends on digital mapping, vehicle tracking methods like GNSS, onboard equipment, real-time connectivity, and additional databases for traffic rules. Geofencing offers degrees of control, from informing and alerting drivers about speed limits to actively restricting vehicle speed, with possibilities for static, dynamic, and smart adaptations. Applications range from enhancing traffic safety by alerting drivers and controlling vehicle speed to improving transport efficiency through optimized route selection and environmental benefits by reducing emissions and noise pollution. However, regulatory challenges persist, such as the absence of type-approved geofencing equipment and the need to define functional requirements rather than specific technologies in legal frameworks, presenting both opportunities and obstacles for its implementation in road traffic management and procurement processes. The first step in public procurement involves laying the groundwork by comprehensively understanding the buying organization's needs and market capabilities to meet them. The city identified key goals such as safe travel and driver assistance. The city explored existing agreements and engaged operators for a geofencing pilot to address speed compliance and traffic safety concerns, alongside researching market options and risks associated with third-party equipment installation and data privacy. Alternatives like ISA and ADAS were considered but deemed insufficient. In the second step the procurement is carried out, which includes tasks such as producing procurement documents, advertising, evaluating tenders, and ultimately selecting a supplier. The city procured the geofencing technology by direct public procurement and used a traditional public procurement to get hold of vehicles and drivers. In the third step of the public procurement implementation is in focus on, executing the pilot and evaluating its outcomes, particularly concerning geofencing technology. Challenges arose during implementation, including difficulties in accurately mapping zones to individual vehicles due to problems with the speed box installed. The city of Gothenburg learned valuable lessons, highlighting the importance of direct communication with drivers, verifying technology before widespread adoption, and close collaboration between all stakeholders. Despite challenges, the pilot provided valuable data and insights, with recommendations offered for future geofencing initiatives, emphasizing early supplier dialogue, thorough testing, user experience understanding, and involving relevant stakeholders from the outset. In this report insights, advice and lessons learned are also shared. Technical hurdles include the lack of standardized geofencing, difficulty in retrofitting diverse vehicle fleets, and limited market availability. Organizational challenges encompass the need for a needs-driven approach, internal and external collaboration, and balancing technology with user acceptance. Concerns about data privacy and driver behaviour emerge, requiring careful navigation of GDPR regulations. Strategically deciding the city's role in IT-solutions, data collection, and responsibility for vehicle behaviour poses business-related challenges. The report concludes that while geofencing technology isn't yet ready for full-scale implementation, further pilots are necessary for development. Future work involves exploring alternative solutions, enhancing internal processes, and conducting larger pilots to advance understanding and implementation of geofencing technology.

    Geostängslade BK4-transporter vid bropassager och på tjälade vägar2023Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Geofenced heavy trucks to protect bridges at crossings allowing higher weight on frozen roads Winter is our friend. When the road body is deep frozen it can handle more weight than during the rest of the year. However, the bridges are not affected by the cold weather, and they are therefore still vulnerable to increased loads. How can we allow increased loads on frozen roads while ensuring protection of the bridges? In this report, we share our insights from a project with the idea of using geofencing to protect the bridges. The geofencing technology ensures that the truck drives at a lower speed over the bridge and the bridge can withstand loads up to 74 tons since decreased speed reduces dynamic loads. If the road keeper can get guarantees that all heavy trucks drive at a low speed over the bridge, heavier traffic can be accommodated. This technology would of course also be beneficial to use across bridges in Europe regardless of the climate. ' The project “Frozen roads and 74 tons”, paid by the Swedish Transport Administration, consisted of three parts. One part was a pilot study during winter 22/23 demonstrating trucks from AB Volvo and Scania loaded with 74 tons using geofencing when the trucks passed over weak bridges. A speed limit, i.e. 50 km/h, was imposed in a zone around each bridge, whose coordinates were stored in the digital map accessible through the trucks’ Fleet Management System. Two different geofencing technologies were tested: on the one hand Scania’s system with “active” geofencing, where the truck was programmed to maintain the allowed speed over the bridge and calculated and implemented this itself (the driver could, however, override this by pushing the gas pedal to the floor); on the other hand AB Volvo’s system with “passive” geofencing, where the driver received a warning message when approaching the zone and would then slow down if necessary. The drivers were interviewed before and after the pilot about their experience. The results from the pilot showed that if the technology is verified, the truck will do the right thing and is on the right road network when the technology is activated. The drivers also liked geofencing. Geofences thus work in practice. The second part of the project was about quantifying the societal benefits of using geofencing. More efficient planning, control and follow-up can lower costs, reduce environmental impact, and increase traffic safety. Calculations in the project show that about 12 percent of timber transports in Norrland use frozen roads. They can benefit from the technology and if the technology is introduced, the industry would make savings of the equivalent of SEK 15 million / year and reduced energy use equivalent to 280 cubic meter diesel. At national level, this corresponds to an energy efficiency potential of 0.12 percent. The third part of the project was about policy and regulation. Can we use the current legislation, or do we need new legislation to scale the use of geofencing across bridges? How can we ensure compliance? How can we share data? How can we handle EU trade barriers? In the report, we have suggestions for policy and legislation to implement the geofencing technology to protect sensitive bridges. Our analysis shows that it is possible with today's regulations for an authority to introduce regulations on geofences. Such rules should preferably be based on functional requirements and a system of self-monitoring.

    Legal utredning för datadelning varor och transporter2021Rapport (Övrigt vetenskapligt)
    Abstract [en]

    In this project, the Swedish Transport Administration wanted to have two different tracks investigated from a legal perspective. We have chosen to call the first track a “matchmaking service for freight” to optimize the utilization of available cargo space. There is an assignment from the government to the Swedish Transport Administration to work with this issue based on horizontal collaborations and open data. The second track is about the development of new technology enabling new ways of collecting railway data based on RFID and the possibility of filming passing trains, which in turn raises legal questions about how the Swedish Transport Administration can use collected data.

    After analysing the two tracks based on current regulations, interviewing different actors, arranging workshops with different stakeholders, and meetings with experts in the fields, our conclusions are as follows:

    So far, it is unclear who will be appointed to be matchmaker and how the matchmaking service is intended to work as the Swedish Transport Administration´s assignment will last for another ten years. Our assessments at this early stage of the Swedish Transport Administration´s assignment aims more to provide advice on how the matchmaking service can be designed in the future. Above all, we foresee that competition law will be a challenge as it regulates horizontal collaborations. In the future, it needs to be investigated more what benefit consumers get from the matchmaking service and how such service can be designed without distorting competition on the market. The matchmaking service is aimed for product owners. The interviews show that they are prepared to share data provided that they get a benefit from this. The interviews also show that they are not used to sharing data in such a way that is required for a matchmaking service to function properly. We therefore believe that work will have to be put on making the product owners understand the benefit of data sharing to facilitate the introduction of a matchmaking service, e.g. by showing good examples to get product owners to think in new ways and dare to take the step. It is also unclear what is meant by open data and how it is compatible with copyright/trade secrets. That part of the assignment needs to be further elucidated.

    In our opinion, the Swedish Transport Administration has the copyright to RFID data, and it is also from a copyright perspective that the Swedish Transport Administration has so far shared RFID data (through contracts) with others. One hope with RFID is that the technology will make an impact on the entire European railway network, which in turn raises the question of how RFID data can legally be shared. Our assessments are that it would be possible to turn RFID data into open data to enable data sharing within the EU, but this is something that needs to be discussed further with all the actors involved.

    Data collection by filming passing trains is still at an early trial stage. Above all, we see that more work needs to be done to make data collection compatible with the GDPR and the Swedish Camera Surveillance Act. When trains are filmed, information is also collected about the load on the wagons. We see that this can lead to safety risk, which need to be addressed in the future work.

    Peer-to-peer service sharing platforms: Driving share and share alike on a mass-scale2013Ingår i: International Conference on Information Systems (ICIS 2013): Reshaping Society Through Information Systems Design, 2013, Vol. 4, s. 2964-2978Konferensbidrag (Refereegranskat)
    Abstract [en]

    The sharing economy has been growing continuously in the last decade thanks to the proliferation of internet-based platforms that allow people to disintermediate the traditional commercial channels and to share excess resources and trade with one another effectively at a reasonably low transaction cost. Whereas early peer-to-peer platforms were designed to enable file sharing and goods trading, we recently witness the emergence of a new breed of peer-to-peer platforms that are designed for ordinary service sharing. Ordinary services entail intangible provisions and are defined as an economic activity that generates immaterial benefits and does not result in ownership of material goods. Based on a structured analysis of 41 internet-based rideshare platforms, we explore and layout the unique characteristics of peer-to-peer service sharing platforms based on three distinct temporal patterns that entail specific consequences for platform use as well as provide insights about their overall design imperative.

    DUAL PERSPECTIVES ON MULTI-CONTEXTUALITY OF DATA IN DIGITAL PLATFORM ESTABLISHMENT2020Ingår i: Proc of 21st CINet Conference, 2020Konferensbidrag (Refereegranskat)
    Abstract [en]

    Innovation in ecosystems becomes increasingly attractive for incumbents as the technical complexity increases and complementarities play an increasingly important role for global competition. Digital platforms are becoming one of the primary means to that end, where incumbents can gain scale effects and reap the benefits of the creative crowd while maintaining ownership of the core product. But a lion’s share of these platforms hinges on the accessibility of data, and the view of the value and ownership of this data differs among actors in the system. This paper accounts for a case study of two type actors in an innovation ecosystem; the keystone firm and the third-party service provider. From interviews with representatives of these actors, we formulate a tentative description of their perspective on the sharing of data in the ecosystem. We find that these perspectives differ in terms of data contextuality and customer value. We argue that these differing perspectives are at the crux of establishing innovation capabilities in ecosystems based on digital platforms.

    Abstract [en]

    Innovation in ecosystems becomes increasingly attractive for incumbents as the technical complexity increases and complementarities play an increasingly important role for global competition. Digital platforms are becoming one of the primary means to that end, where incumbents can gain scale effects and reap the benefits of the creative crowd while maintaining ownership of the core product. But a lion’s share of these platforms hinges on the accessibility of data, and the view of the value of this data differs among actors in the system. This paper accounts for a case study of two type actors in an innovation ecosystem: the core actor (OEM) and the peripheral actor (third party service provider). From interviews with representatives of these actors, we find that their perspectives on the data and its usefulness outside its intended context differ. We label the perspectives purposive and multi-contextual; we formulate their descriptions and outline managerial implications. We argue that these differing perspectives are at the crux of establishing innovation capabilities in ecosystems based on digital platforms.

    Wicked Cases and Late Binding in System of Systems2022Ingår i: 2022 17th Annual System of Systems Engineering Conference, SOSE 2022, Institute of Electrical and Electronics Engineers Inc. , 2022, s. 354-359Konferensbidrag (Refereegranskat)
    Abstract [en]

    Systems of Systems is being applied in ever more complex contexts. This paper reports findings from a city logistics initiative. As many other environmental challenges, this setting can be characterized as 'wicked', e.g. the organizations that need to be involved solving the issues are contributing causes and there is no obvious single authority able to make decisions. Our findings suggest that such settings lead to vagueness and 'late binding' of key actors and incentives making the early modelling phases highly challenging. Supplementing the wave model of SoS development, we describe specific coping mechanisms for such settings including designing for multiple SoS archetypes and identifying and prioritizing archetype-generic capabilities.

    A Census of Swedish Government Administrative Authority Employee Communications on Cybersecurity during the COVID-19 Pandemic2020Ingår i: 2020 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM), IEEE, 2020Konferensbidrag (Refereegranskat)
    Abstract [en]

    Cybersecurity is the backbone of a successful digitalization of society, and cyber situation awareness is an essential aspect of managing it. The COVID-19 pandemic has sped up an already ongoing digitalization of Swedish government agencies, but the cybersecurity maturity level varies across agencies. In this study, we conduct a census of Swedish government administrative authority communications on cybersecurity to employees at the beginning of the COVID-19 pandemic. The census shows that the employee communications in the beginning of the pandemic to a greater extent have focused on first-order risks, such as video meetings and telecommuting, rather than on second-order risks, such as invoice fraud or social engineering. We also find that almost two thirds of the administrative authorities have not yet implemented, but only initiated or documented, their cybersecurity policies.

    Cybersecurity work at Swedish administrative authorities: taking action or waiting for approval2024Ingår i: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In recent years, the Swedish public sector has undergone rapid digitalization, while cybersecurity efforts have not kept even steps. This study investigates conditions for cybersecurity work at Swedish administrative authorities by examining organizational conditions at the authorities, what cybersecurity staff do to acquire the cyber situation awareness required for their role, as well as what experience cybersecurity staff have with incidents. In this study, 17 semi-structured interviews were held with respondents from Swedish administrative authorities. The results showed the diverse conditions for cybersecurity work that exist at the authorities and that a variety of roles are involved in that work. It was found that national-level support for cybersecurity was perceived as somewhat lacking. There were also challenges in getting access to information elements required for sufficient cyber situation awareness.

    Cirkulärt omhändertagande av solcellspaneler och vindturbinblad för vindkraftverk2024Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    I regleringsbrevet för 2023 fick Energimyndigheten i uppdrag av regeringen att utreda hur solcellspaneler och vindturbinblad till vindkraftverk i högre utsträckning ska kunna tas om hand på ett giftfritt och cirkulärt sätt i enlighet med avfallshierarkin. Redovisningen av detta regeringsuppdrag, rapporten Från avfall till resurs – Förslag för en mer cirkulär hantering av solcellspaneler och vindturbinblad, ER 2024:11, baseras på denna underlagsrapport som har tagits fram av forskningsinstitutet RISE på uppdrag av Energimyndigheten. Analyser, slutsatser och förslag/rekommendationer som framförs i rapporten är författarnas egna.En fortsatt utbyggnad av fossilfri elproduktion är av stor vikt för att vi ska kunna nå Sveriges energi- och klimatmål. För att utbyggnaden i sig ska vara hållbar är det viktigt att vi redan nu planerar för hur avfallet från dessa elproduktionsanläggningar ska förebyggas, minimeras och sedan hanteras.Det finns redan i dagsläget aktörer som har utvecklat och håller på att utveckla ett flertal olika lösningar för ökad cirkularitet. Dessa möjligheter kan tas tillvara och främjas genom regelbunden kartläggning och genom att arbeta gemensamt inom EU. Genom ett sådant arbete finns det också större möjligheter att etablera industriella värdekedjor i Sverige för hanteringen av avfallet från solcellspaneler och vindturbinblad.En cirkulär hantering av avfall ger ett betydligt mindre avtryck på miljön än det som en linjär hantering ger upphov till. Det är viktigt att de aktörer som tillhandahåller fossilfri elproduktion tar ansvar under hela livscykeln och att det finns goda förutsättningar för aktörerna att göra det.

    Gender Aspects of Shared Mobility Services from a System of Systems Perspective2024Ingår i: 2024 19th Annual System of Systems Engineering Conference, SoSE 2024, Institute of Electrical and Electronics Engineers Inc. , 2024, s. 30-35Konferensbidrag (Refereegranskat)
    Abstract [en]

    System of systems (SoS) are intended to solve problems, provide more effective services, and enable greater collaborative behaviour. For SoS operating within the mobility domain, where the usefulness of the SoS solution largely depends on how many people will use the SoS, it is necessary to consider if there are potential gender aspects of the user that may negatively impact the SoS usefulness. In this study, we present the results from a literature survey on gender aspects of the usage of new mobility solutions and use this to present a conceptual model for how gender affects SoS mobility usage and how SoS stakeholders can act to impact this influence.The literature survey identified several gender aspects of using new mobility solutions. These aspects can significantly impact the usefulness and utilisation of SoS within the mobility domain. The conceptual model developed from the survey findings highlights the importance of considering gender in SoS mobility usage. By understanding how gender influences the usage of such SoS, stakeholders can take action to address any potential negative impacts. This model provides a framework for designing more inclusive and user-friendly SoS solutions that cater to the needs and preferences of all users, regardless of gender.

    Crowdsourcing and Public Transportation: Barriers and Opportunities2021Ingår i: Proc of 23rd ITS Biennial Conference, 2021Konferensbidrag (Refereegranskat)
    Abstract [en]

    In the last decade, private companies have successfully used crowdsourcing to revolutionise mobility, while public transport companies are still mostly failing to utilise the benefits of crowdsourcing. The application of crowdsourcing in public transport is a new area of academic research, and research on crowdsourcing en route in real-time is missing. This research aims to address this gap, explore opportunities and challenges of this type of crowdsourcing, and conceptualise this phenomenon. The research is based on empirical data collected in five Northern European countries. Our research findings help identify areas where crowdsourcing en route can add value to public transport: new forms of communication, opportunities to communicate with third parties, and improved transit planning and optimisation. Identified challenges are related to behavioural change for users, a need to develop infrastructure to enable crowdsourcing en route, and financial rationalities.

    A Simulation Study on Effects of Platooning Gaps on Drivers of Conventional Vehicles in Highway Merging Situations2021Ingår i: IEEE transactions on intelligent transportation systems (Print), ISSN 1524-9050, E-ISSN 1558-0016Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Platooning refers to a group of vehicles that--enabled by wireless vehicle-to-vehicle (V2V) communication and vehicle automation--drives with short inter-vehicular distances. Before its deployment on public roads, several challenging traffic situations need to be handled. Among the challenges are cut-in situations, where a conventional vehicle--a vehicle that has no automation or V2V communication--changes lane and ends up between vehicles in a platoon. This paper presents results from a simulation study of a scenario, where a conventional vehicle, approaching from an on-ramp, merges into a platoon of five cars on a highway. We created the scenario with four platooning gaps: 15, 22.5, 30, and 42.5 meters. During the study, the conventional vehicle was driven by 37 test persons, who experienced all the platooning gaps using a driving simulator. The participants' opinions towards safety, comfort, and ease of driving between the platoon in each gap setting were also collected through a questionnaire. The results suggest that a 15-meter gap prevents most participants from cutting in, while causing potentially dangerous maneuvers and collisions when cut-in occurs. A platooning gap of at least 30 meters yield positive opinions from the participants, and facilitating more smooth cut-in maneuvers while less collisions were observed.

    A Novel Risk Indicator for Cut-In Situations2020Ingår i: 2020 IEEE 23rd International Conference on Intelligent Transportation Systems, ITSC 2020, Institute of Electrical and Electronics Engineers Inc. , 2020Konferensbidrag (Refereegranskat)
    Abstract [en]

    Cut-in situations occurs when a vehicle intentionally changes lane and ends up in front of another vehicle or in-between two vehicles. In such situations, having a method to indicate the collision risk prior to making the cut-in maneuver could potentially reduce the number of sideswipe and rear end collisions caused by the cut-in maneuvers. This paper propose a new risk indicator, namely cut-in risk indicator (CRI), as a way to indicate and potentially foresee collision risks in cut-in situations. As an example use case, we applied CRI on data from a driving simulation experiment involving a manually driven vehicle and an automated platoon in a highway merging situation. We then compared the results with time-to-collision (TTC), and suggest that CRI could correctly indicate collision risks in a more effective way. CRI can be computed on all vehicles involved in the cut-in situations, not only for the vehicle that is cutting in. Making it possible for other vehicles to estimate the collision risk, for example if a cut-in from another vehicle occurs, the surrounding vehicles could be warned and have the possibility to react in order to potentially avoid or mitigate accidents.

    Safety and experience of other drivers while interacting with automated vehicle platoons2021Ingår i: Transportation Research Interdisciplinary Perspectives, E-ISSN 2590-1982, Vol. 10, artikel-id 100381Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It is currently unknown how automated vehicle platoons will be perceived by other road users in their vicinity. This study explores how drivers of manually operated passenger cars interact with automated passenger car platoons while merging onto a highway, and how different inter-vehicular gaps between the platooning vehicles affect their experience and safety. The study was conducted in a driving simulator and involved 16 drivers of manually operated cars. Our results show that the drivers found the interactions mentally demanding, unsafe, and uncomfortable. They commonly expected that the platoon would adapt its behavior to accommodate a smooth merge. They also expressed a need for additional information about the platoon to easier anticipate its behavior and avoid cutting-in. This was, however, affected by the gap size; larger gaps (30 and 42.5 m) yielded better experience, more frequent cut-ins, and less crashes than the shorter gaps (15 and 22.5 m). A conclusion is that a short gap as well as external human–machine interfaces (eHMI) might be used to communicate the platoon's intent to “stay together”, which in turn might prevent drivers from cutting-in. On the contrary, if the goal is to facilitate frequent, safe, and pleasant cut-ins, gaps larger than 22.5 m may be suitable. To thoroughly inform such design trade-offs, we urge for more research on this topic. © 2021 The Author(s)

    A Roadmap Towards Remote Assistance: Outcomes from Multidisciplinary Workshop at the 2023 Intelligent Vehicles Symposium2024Konferensbidrag (Refereegranskat)
    Abstract [en]

    Remote operation of highly automated vehicles (HAVs) may include occasional assistance from a human remote operator that is located outside the HAVs. Remote assistance typically delegates only highlevel guidance tasks to the remote operators such as authorizing a driving maneuver or specifying a new driving path. As remote assistance is fairly unexplored, there are still several research challenges. These challenges were discussed by experts from academia and industry in a multidisciplinary workshop at the 2023 IEEE Intelligent Vehicles Symposium. As a result of the workshop, this paper presents a list of most pressing research questions in the following areas: human-machine interaction and human factors, design of the remote station, design of the HAVs. It also outlines a roadmap for future research on remote assistance of HAV, thereby informing interdisciplinary studies and facilitating the benefits of HAVs before full autonomy can be reached.

    En not om att mäta kapacitet på järnväg2022Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Följande rapport introducerar ett nytt kapacitetsmått för trafik på järnväg. Syftet med det föreslagna måttet är att det skall vara användbart vid förplanering av järnvägstrafik, innan järnvägsföretag och andra sökanden lämnar in sina ansökningar om trafik och kapacitetstilldelningen slutförs. Kapacitetsmåttet utgår från det gängse sättet att presentera en tågplan, den så kallade tidtabellsgrafen, eller i branschen refererad till som bara ”grafen”. För varje spårsträcka som tågläget belägger så utgör kapacitetskonsumtionen ytan som upptas i grafen. Denna yta är summan av varje individuell signalsträckas längd multiplicerat med tiden som tågläget belägger hela spårsträckan. Detta utgör kapacitetskonsumtionen för tågläget. Måttet blir intressant i de tidigare processtegen innan ansökan om kapacitet. Då ansökan ännu inte är genomförd så finns inga sökta avgångs- och ankomsttider, däremot en prognos vad som kommer sökas (t.ex. genom den i TTR angivna händelsen Capacity Needs Announcement). Genom att lägga på ett tidsfönster kan varje prognosticerat tågläge abstraheras att avgå/ankomma inom detta tidsfönster. Kapacitetskonsumtionen är dock konstant, och denna fördelas över tidsfönstret. Genom att för varje tidsögonblick ackumulera den fördelade kapacitetsåtgången fås en kapacitetsanvändningsplan. Denna är en abstraktion av det tänkta framtida schemat (tågplanen) och kräver således inte en konfliktfri tågplan som utgångspunkt. En kapacitetsanvändningsplan kan således realiseras av många olika scheman som realiserar den. Tanken är att kapacitetsanvändningsplanen, om prognosen för framtida trafik är rätt, på ett korrekt sätt lyckats abstraherat den framtida tågplanens konkreta schema. Hänsyn måste tas till de tidsmässiga kostnader som uppstår för att tåglägen har olika hastighet och på enkelspår går i olika riktning. Detta hanteras i analogi med andra industrisektorer med ställtid, vilket också är kapacitetskonsumtion och således ingår i kapacitetsanvändningsplanen. Utöver detta måste hänsyn i kapacitetsanvändnings-planen tas till tid som behövs för att reglera möten och förbigångar på omgivande driftplatser och ger upphov till ytor som inte längre kan nås i ett konkretiserat schema. Då denna kapacitetskonsumtion adderas till den övriga beskrivna kapacitets-konsumtionen har en kapacitetsbudget skapats vars syfte är att klargöra förutsättningarna för vilken trafik som kan bedrivas och som skall kunna realiseras i ett schema (tågplan) efter att ansökan om kapacitet skett. Det i denna rapport beskrivna måttet för kapacitetskonsumtion utgör en brygga mellan de tidigare processtegen i kapacitetstilldelningsprocessen och de senare.

    RIT– Reservkapacitet i tilldelningsprocessen: Underlagsrapport 12020Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Kapacitet på järnvägens infrastruktur tilldelas en gång per år till olika aktörer på järnvägen som har behov av järnvägskapacitet. Detta inkluderar järnvägsbolag såsom kommersiella person- och godstågsoperatörer, regionala kollektivtrafikmyndigheter, större bolag med transportbehov samt underhållsentreprenörer. Dessa har alla olika behov och värdesätter olika egenskaper för sina transporter, vissa har behov av långsiktigt stabil kapacitetstilldelning, andra har behov av större dynamik. Svensk järnvägslag ställer krav (kommande ur EU:s direktiv på området) att det finns reservkapacitet reserverat i den årliga tågplanen, som beskriver hur infrastrukturen skall användas. Reservkapacitet är kapacitet som medvetet och på goda grunder undanhållits i den årliga kapacitetstilldelningsprocessen då det finns behov av attraktiv kapacitet under innevarande tågplan. Reservkapacitet är således inte att likställa med restkapacitet vilket är den kapacitet som blir över efter att tågplanen är fastställd. Det är dock i dagsläget oklart hur reservkapacitet skall representeras i tågplaneprocessen, storleksmässigt avgöras och tidsmässigt placeras och planeras. Projektet RIT, Reservkapacitet i tilldelningsprocessen, söker svar på dessa frågor. Projektet RIT är också involverat i det av RNE (Rail Net Europe) initierade projektet TTR, Redesign of the international timetabling project (tidigare Timetable review) då det förslag till ändrad tilldelning av kapacitet som tagits fram i TTR innehåller avsevärt större krav på reservering av kapacitet i termer av en Capacity Portfolio, Capacity bands med reservering av kapacitet för upp till 3 års rullande planering (Rolling Planning) samt begreppet Safeguarding dvs att kapaciteten är reserverad och utlovad till aktör men inte nödvändigtvis detaljerat schemalagd. Samtliga dessa begrepp kräver förmåga att värdera nyttan av att reservera samt praktiskt hur reserveringen av kapacitet kan göras och slutligen realiseras som tågläge och operativt genomföras som en tågtransport eller underhållsarbete. Föreliggande statusrapport i projektet RIT beskriver inte ett färdigt resultat utan fokuseras på i huvudsak behovsanalys, formalisering av problemet, angreppssätt och tänkt modell.

    Värdering av tågtrafik i TTRs förhandsplanering - Slutrapport från projektet TOT, Tjänsteutbud Och Transportkapacitets-försörjning på järnväg2023Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Valuation of train traffic in TTR's Advance planning Europe's infrastructure authorities organized in RNE, Rail Net Europe, and Europe's railway undertakers organized in FTE, Forum Train Europe, have for several years been running an international development programme called "Redesign of the International Timetabling Process" (originally "TimeTable Review", abbreviated TTR) aiming at trans-forming the capacity allocation process on railways. The results from TTR have in turn largely influenced the European Commission's proposal for a new regulation in the area. An important component, at least for Swedish conditions, is an increased degree of pre-planning which results in a supply/offer of pre-planned train paths. Capacity will also be reserved during the preparation of the annual timetable for later allocation which can be up to 3 years ahead. This places great demands on the infrastructure manager’s ability to be able to reserve capacity, value capacity (even under uncertainty) and safeguard the capacity characteristics that have been reserved, as well as having tools to support that. This report summarizes the work carried out within the project “Service and Transport capacity supply on rail”, TOT. The goal of TOT has been to investigate the possibilities of using the already defined Priority categories, used in the conflict phase of today’s process, for valuation and prioritization of train transports in the Advance planning phase of the TTR process, i.e., before railway undertakers formally apply for capacity. To summarize TOT’s results, the Swedish prioritization criteria can be used for valuation train traffic in TTR's Advance planning phase. Someone, preferably the infrastructure manager based on own experience, needs to decide which priority category different pre-planned transports should be classified as. The assessment should be made based on the society's utility that a particular transport is being performed. The Priority categories are not suited to e.g., decide in a competitive situation between equal actors which one that should be allocated a pre-planned train path. For this, a complementary method is needed to determine who should be allocated the capacity. Ideally, the Swedish Priority category also needs further development to, among other things, valuate traffic regularity as well as marginal effects when there are several similar paths planned during a limited time frame. There is a large need for a valuation function for the infrastructure manager during the preplanning phase, to be able to prioritize among different foreseen needs. The valuation model needs to value the socio-economic utility of the intended use of the infrastructure in the coming timetable where capacity shortages can be foreseen due to conflicting demands. For this purpose, the Swedish prioritization categories can work as a basis.

    Reservkapacitet i tilldelningsprocessen (RIT) – Slutrapport2022Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Reserve capacity in Railway capacity allocation. Each year railway undertakings (RUs) apply for capacity to run trains on the railway infrastructure. The infrastructure manager (IM) should make a complete timetable for all applications together with capacity restrictions when maintenance etc must be performed. In this process, referred to as the capacity allocation process, the IM should also schedule some reserve capacity for later use during the execution of the plan. The reserve capacity then competes with the applied capacity of the RUs, since it is only motivated to introduce reserve capacity where there is a capacity scarcity. If there is plenty of rest capacity (capacity that no one applied for in the yearly process), then there is no need for reserve capacity. Since reserve capacity competes with all other capacity applied for in the yearly capacity allocation process, the amount, location and lines where reserve capacity is introduced must be founded in fair and sound principles in order for the RUs in the yearly process to accept the costs taken to make room for the reserve capacity. This report addresses such models and methods for the Swedish capacity allocation process. The report in part summarizes in condensed form the two earlier reports that have been published, as well as reports some new material regarding process descriptions, data analyses of previous years’ timetables and interviews with three different RUs. The report also gives some recommendations to the Swedish IM Trafikverket about tools for representing reserve capacity, design of the process and how to allocate paths based on reserve capacity once capacity has been reserved. One key recommendation is that a new timetabling object should be introduced, called Capacity reservation, CR. A CR is a named (has identity) timetabling object that can be used in a train path in the future. If an RU wants to use such a CR in a train path, the RU must apply for it and exceed a valuation criterion to be able to get it. This valuation criterion is a connection to the costs that other yearly applied traffic has to take in order to make room for the reserve capacity. CRs are managed (not “allocated”) by the IM and are not allocated to an RU or entrepreneur until they have applied for it. CRs are available for allocation after the timetable is finalized and the short-term process (ad hoc) is started, including the process step Late path requests. The report also relates the models and methods to the upcoming new capacity allocation process called Timetabling and capacity redesign, TTR. TTR introduces Advance planning, i.e. planning in advance of the RU allocations. For this to work, it is crucial to be able to reserve capacity in various forms, both segmentation and reserve over time (safeguarding).

    RIT – Reservkapacitet i tilldelningsprocessen : Underlagsrapport 22022Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Svensk järnvägslagstiftning ställer krav på infrastrukturförvaltaren att denne skall reservera kapacitet under den årliga kapacitetstilldelningsprocessen för tilldelning under tågplanens genomförande. Sådan så kallad reservkapacitet, till skillnad mot restkapacitet som är kapacitet som blir över vid årlig tilldelning, skall möjliggöra en följsamhet för tillkommande behov men även hantering av uppkommande förändringar så att effektiv användning av infrastrukturen säkerställs. Forsknings- och innovationsprojektet RIT, Reservkapacitet i Tilldelningsprocessen, studerar hur reservkapacitet kan åstadkommas med beaktande av krav på transparens, och rättvisa för aktörerna samt nytta för samhället. Vägledande för resultaten i RIT är att järnvägens aktörer skall kunna ställa sig bakom de principer som projektet RIT tar fram. Denna underlagsrapport två fokuserar på om och hur ett underlag för avsättning av reservkapacitet skall kunna tas fram. Två metoder har identifierats, dels att undersöka tidigare tågplaner och mängden sökta tåglägen under tågplanernas genomförande, dels möjligheterna att genom intervjuer och årligt återkommande marknadsundersökningar från aktörerna kunna identifiera behovet av reservkapacitet. Denna rapport omfattar huvudsakligen den första av de två möjliga sätten att identifiera reservkapacitet. En process som på ett grovt plan beskriver en möjlig framtida hantering av reservkapacitet ges också i rapporten. Denna process är sammanvävd med den nuvarande kapacitetstilldelningsprocessen. Ett huvudresultat i rapporten är att det är svårt att förutse nästa tågplans behov av reservkapacitet baserat på data som finns tillgänglig idag. Tidigare ansökningar visar endast det som den sökande tror sig kunna få (eller har fått reda på att denna troligen kan få sig tilldelat) vilket inte avspeglar det faktiska behovet som den sökande egentligen skulle vilja söka. Saknas gör dessutom alla de ansökningar som den sökande inte finner någon mening att söka (då t.ex. kapaciteten på nyckelsträckor är fullbelagd). Vidare söks kapacitet som skulle kunna sökas på reservkapacitet (om den funnits) idag spekulativt i den årliga tilldelningen, dvs den sökande söker det denne tror att denne behöver. Sammantaget gör detta, tillsammans med alla tåglägen som söks under tågplanens genomförande i revisionsplaneringen på grund av banarbeten, att dagens data om tillkommande trafik under tågplanen inte utgör en bra grund för att undersöka behovet av nästkommande tågplans behov.

    Drone Navigation and License Place Detection for Vehicle Location in Indoor Spaces2024Ingår i: Lect. Notes Comput. Sci., Springer Science and Business Media Deutschland GmbH , 2024, s. 362-374Konferensbidrag (Refereegranskat)
    Abstract [en]

    Millions of vehicles are transported every year, tightly parked in vessels or boats. To reduce the risks of associated safety issues like fires, knowing the location of vehicles is essential, since different vehicles may need different mitigation measures, e.g. electric cars. This work is aimed at creating a solution based on a nano-drone that navigates across rows of parked vehicles and detects their license plates. We do so via a wall-following algorithm, and a CNN trained to detect license plates. All computations are done in real-time on the drone, which just sends position and detected images that allow the creation of a 2D map with the position of the plates. Our solution is capable of reading all plates across eight test cases (with several rows of plates, different drone speeds, or low light) by aggregation of measurements across several drone journeys.

    Cooperative Intelligent Transport Systems: Choreography-Based Urban Traffic Coordination2021Ingår i: IEEE transactions on intelligent transportation systems (Print), ISSN 1524-9050, E-ISSN 1558-0016, Vol. 22, nr 4, s. 2088-2099Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    With the emerging connected automated vehicles, 5G and Internet of Things (IoT), vehicles and road infrastructure become connected and cooperative, enabling Cooperative Intelligent Transport Systems (C-ITS). C-ITS are transport system of systems that involves many stakeholders from different sectors. While running their own systems and providing services independently, stakeholders cooperate with each other for improving the overall transport performance such as safety, efficiency and sustainability. Massive information on road and traffic is already available and provided through standard services with different protocols. By reusing and composing the available heterogeneous services, novel value-added applications can be developed. This paper introduces a choreography-based service composition platform, i.e. the CHOReVOLUTION Integrated Development and Runtime Environment (IDRE), and it reports on how the IDRE has been successfully exploited to accelerate the reuse-based development of a choreography-based Urban Traffic Coordination (UTC) application. The UTC application takes the shape of eco-driving services that through real-time eco-route evaluation assist the drivers for the most eco-friendly and comfortable driving experience. The eco-driving services are realized through choreography and they are exploited through a mobile app for online navigation. From specification to deployment to execution, the CHOReVOLUTION IDRE has been exploited to support the realization of the UTC application by automatizing the generation of the distributed logic to properly bind, coordinate and adapt the interactions of the involved parties. The benefits brought by CHOReVOLUTION IDRE have been assessed through the evaluation of a set of Key Performance Indicators (KPIs).

    The collaborative economy: A disruptive innovation or much ado about nothing?2014Ingår i: 35th International Conference on Information Systems: Building a Better World Through Information Systems, ICIS 2014Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    An economy based on the exchange of capital, assets and services between individuals has grown significantly, spurred by proliferation of internet-based platforms that allow people to share underutilized resources and trade with reasonably low transaction costs. The movement toward this economy of "sharing" translates into market efficiencies that bear new products, reframe established services, have positive environmental effects, and may generate overall economic growth. This emerging paradigm, entitled the collaborative economy, is disruptive to the conventional company-driven economic paradigm as evidenced by the large number of peer-to-peer based services that have captured impressive market shares sectors ranging from transportation and hospitality to banking and risk capital. The panel explores economic, social, and technological implications of the collaborative economy, how digital technologies enable it, and how the massive sociotechnical systems embodied in these new peer platforms may evolve in response to the market and social forces that drive this emerging ecosystem.

    An Agent-Based Ontology to Support Modeling of Socio-Technical Systems-of-Systems2024Ingår i: INCOSE International Symposium, Vol. 34, nr 1, s. 1705-1718Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Systems-of-systems are characterized by the independence of their constituent elements. Such an element is usually socio-technical, comprising technology, humans, or organizations. To capture its independence, it needs to be viewed as an intelligent agent that relies on an internal model of the world for its decision-making. Hence, a system-of-systems model will include multiple agents that inside themselves contain different models of the same system-of-systems. Describing these overlapping subjective models and their usage by the agents is essential to properly understand the resulting behavior of the overall system-of-systems. Current modeling practices are not well suited for dealing with this, and the paper therefore outlines an ontology that makes the agents and their internal models more explicit. The paper also discusses the implications such models have on systems engineering practices and how they address known system-of-systems engineering pain points.

    Systems-of-Systems Design Patterns: A Systematic Literature Review and Synthesis2022Ingår i: 2022 17th Annual System of Systems Engineering Conference, SOSE 2022, Institute of Electrical and Electronics Engineers Inc. , 2022, s. 171-176Konferensbidrag (Refereegranskat)
    Abstract [en]

    Design patterns are an established approach for reusing knowledge about good solutions to recurring problems. Patterns can be seen as a way of describing the best practices, and have been used in many different fields, ranging from building architecture and city planning to software development. There are also scattered results relating to patterns for systems-of-systems. The purpose of this paper is to summarize and review the literature on patterns for systems-of-systems and make a synthesis of a recommended approach for the field. Specifically, the novel contributions of the paper are to propose a consolidated structure for describing individual patterns and suggest the dimensions along which a pattern catalog can be organized. The paper also summarizes the concrete patterns suggested in the existing literature and classifies them according to the recommended structure.

    What Systems Engineers Should Know About Emergence2022Ingår i: INCOSE International Symposium, 2022, Vol. 32:1, s. 1070-1084Konferensbidrag (Refereegranskat)
    Abstract [en]

    The concept of emergence refers to phenomena that occur on a system level without being present at the level of elements in the system. Since a system is created to achieve certain emergent system-level behavior, while avoiding other emergent properties, a deeper understanding of emergence is crucial to further the field of systems engineering. It has also been identified as one of the key aspects of systems-of-systems. However, the concept has been the topic of much debate in philosophy, systems science, and complexity science for a long time, and there is yet no precise characterization on which there is general agreement. In this paper, a selection of the literature on emergence is reviewed to identify some key characteristics and disputes. The various philosophical points of view are analyzed from the perspective of systems engineering, to sort out what characteristics have practical implications, and which philosophical quiddities are merely of theoretical interest. The paper also relates emergence to systems engineering practices and suggests some tactics for dealing with emergence. Key results are that the inclusion of an explicit observer is essential for understanding and handling emergence, and that emergence is closely related to the amount of information required to describe the system which is also a defining characteristic of complexity.
