Rio de Janeiro, with approximately 12 million people in the metropolitanarea, is working towards its goal to be a modern high-technologycity with an efficient transport system. The City of Rio de Janeiro andthe State of Rio de Janeiro hence invest a lot in the expansion of thephysical infrastructure such as the metro system, development of busrapid transit, city trams, etc. The public transport system has thus inrecent years been significantly improved for both the needs of everydayusers in the city as well as temporary visitors that visited Rio de Janeiroduring events such as the FIFA World Cup in 2014 and the 2016Summer Olympic Games. Moreover, the Strategic Plan 2013-2016 ofRio de Janeiro’s City Council emphasized better integration betweenall modes of public transportation, as well as the implementation oftraffic management technology such as intelligent control of trafficlights, real-time information to users, and monitoring of routes.In addition, there was also a need to invest in corresponding digitalinfrastructure to enable more useful information services foreveryday travel. With more accurate traffic information available andprovided to travelers, it will help to align expectations with the overallperformance of e.g. the public transport system. In other words, thefrustration that typically follows from traffic disturbances can be mitigatedif travelers are well-informed and promptly notified about delays.However, as users acquire more devices and utilize ICT in personalizedand less predictable contexts this development also facesorganizations with a dilemma: how can information and services besupplied pervasively given the user diversity and the limited amountof resources available for service development? To this end, manycities open up their traffic data to enable outsiders to cater for end-userservices. By cooperating with external third-parties who find financialor other incentives to pursue development, public authorities can thenachieve a more pervasive distribution of traffic information, helping thecitizens in their everyday travel as well as nurture new firms and otheractors developing end-user applications.To this end, the project should draw on knowledge and experiencesfrom Sweden at Trafiklab.se – a national innovation platformfor open transport data. Also, the project should create businessopportunities for Swedish actors.
