Abstract [en]

Traffic calming measures, such as speed bumps and elevated crossing points, are used to reduce speed, to prevent overtaking and generally contribute to a safer traffic situation. However, they might also cause increased response times for rescue vehicles (e.g. ambulances or fire trucks). An alternative to the conventional traffic calming measures is so-called smart traffic calming measures. These can determine when a vehicle approaches, whose journey should not be hindered, and adjust to allow for free passage for this vehicle.

This report gives an overview of the problem, and some examples of smart  traffic calming measures are discussed. Special focus is put on the wireless communication necessary to detect emergency vehicles. Furthermore, existing challenges and possible solutions for traffic calming measures and the communication needed to make them smart are discussed.

Abstract [sv]

Trafiklugnande åtgärder, såsom vägbulor och förhöjda övergångsställen, används för att minska hastigheten, hindra farliga omkörningar och generellt bidra till en säkrare trafiksituation. Dock kan de också bidra till att insatstiderna för räddningsfordon (t.ex. ambulanser eller räddningstjänstens släckbilar) förlängs. Ett alternativ till de konventionella trafiklugnande åtgärderna, är s.k. smarta trafiklugnade åtgärder. Dessa kan avgöra när ett fordon närmar sig, vars färd inte bör hindras, och anpassa sig så att fri färd för detta fordon tillåts.

I denna rapport ges en översikt av problemet, och några exempel på smarta trafiklugnade åtgärder diskuteras, med fokus på sådana som hämtar information och styrs med hjälp av trådlös kommunikation. Vidare diskuteras existerande utmaningar och möjliga lösningar för trafiklugnande åtgärder och den kommunikation som krävs för att göra dem smarta.
