Experimenting with city streets to transform urban mobility

Across Europe, cities are trying to radically reduce their reliance on
car-based mobility in order to address sustainability challenges. Two things are lacking in these efforts towards a ‘post-car’ city: a proactive vision of cities that are both sustainable and accessible without cars, and effective strategies to deal with systematic resistance to change. The aim of EX-TRA is to address these shortcomings.


Central to EX-TRA’s approach are transition experiments in city streets, or intentional, temporary changes in street use, regulation and/or form, aimed at exploring systemic change towards a ‘post-car’ city. By way of urban living labs in Amsterdam, Bologna, Milan, Ghent, Munich and London, the project will generate insights into:

Possible combinations of physical design and regulation that increase the types of usage and inclusivity amongst users of city streets

Transport and land use conditions for the purpose of enabling and improving walking and cycling accessibility in city districts

Shared mobility platforms and micro-mobility and freight delivery options which complement attractive streets and accessible districts

Strategies of change that can accelerate the transition towards a ‘post-car’ city.
