The design and redesign of public space are a prerequisite to foster and establish sustainable and active mobility. So far, the impact of interventions in public space in Austria has been assessed and monitored insufficiently. This is mainly due to the lack of a standardised methodology for evaluating the impact of interventions in urban mobility spaces. Consequently, there is no evidence base for the effects of the various interventions made, which would be vital w.r.t transferability and optimisation of planning and implementation to efficiently invest resources.
