Since ten years ago, the reduction of people killed and injured by traffic accidents in theworld and theEUis stagnated. The WHO reports road accidents as the primary cause of death among people younger than 29 years. Moreover, many of these accidents happen in cities, and speeding is a significant source of incidents. The result of this research shows that the evolution of technologies that limit the speed of cars automatically into technologies that allow external control of the speed can reduce this problem in a faster, smarter and more sustainable way in the cities of the EU. Transition
Management and different methods like literature review, situation mapping, a survey (N=189), field observations and GIS analysis were triangulated to assess: The relationship between smart and sustainable urban mobility, and Intelligent Speed Assistance (ISA), awell-knownspeed-limiting technology that now is required in all new models of cars in the EU. The status of cities and citizens in the face of the deployment of this new technology. The challenges attached and the possible roadmap to transition from ISA to speed-control technologies as desired. Additionally, a set of s has been designed to measure a defined concept of readiness and can be used at different levels and exported easily for the evaluation of other technologies.Moreover, along with the findings, possible options
for future research have been identified and complementary or substitute measures to reduce the impact or accelerate the transition.
