EX-TRA has worked across six European cities. In each of these cities, a series of street experiments were selected as case studies in our research. We call these testbeds.

Research into each of these testbeds has been used to: generate insights into which combinations of physical design and regulation lead to a greater variation of uses and inclusivity in city streets, and how such changes impact the well-being of citizens, improve understanding of the interaction between behavioural responses to novel street designs/regulations and wider attitudes towards a transition to post-car cities.
