EX-TRA works across six cities, and in each of these cities, a series of street experiments will be selected to act as case studies in our research. We call these testbeds.
Research into each of these testbeds will be 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.
Data about a variety of the testbeds will be collected using Commonplace's online engagement platform.
Via Commonplace, residents are able to give feedback on what they think about a testbed in their local area. To view these Commonplace platforms, select one of the testbed images, and follow the link to commonplace at the end of the description.
For other testbeds, data is being collected using the IAPI. The IAPI (Inclusive Accessibility by Proximity Index) is a quantitative tool developed within the EXTRA project for assessing the level of access, through active mobility, to a basket of daily, essential services at the district level. IAPI measures accessibility by considering how the quality of the neighborhood’s paths and public spaces can influence the walkability and cyclability of three modes: pedestrians, people with reduced mobility, and cyclists. The tool could be used to evaluate differences in access to selected services from different areas of a city and neighborhood to orient measures for accessibility improvement (i.e., street experiments, paths redesign). By using open data - mainly from OSM – possibly integrated with crowdsourced information, the IAPI is designed to maximize scalability, transferability, and the level of customization for context-sensitive applications.
