To reduce car orientation of cities and trigger a major shift towards sustainable transport, we need to raise the awareness of decision-makers / citizens, to change the travel attitude and travel behaviour of people. In the heart of our approach is the concept of “Show and Tell”: a) the project enables cities to apply innovative methods based on tactical urbanism/placemaking/tactical transit practices to SHOW citizens (and decision-makers) through pop-up interventions what it would be like to have streets, parks, public spaces not dominated by cars. b) the project develops innovative digital campaigning tools/methods to TELL (explain) people the risks of car-oriented urban mobility. The term tactical urbanism (pop-up urbanism, DIY urbanism, guerrilla urbanism) describes temporary, low-cost interventions, aimed at improving local neighbourhoods, experimenting with new solutions to specific challenges. Using temporary solutions enables local actors to test new (often innovative) solutions to local challenges before making massive financial commitments and irreversible changes. Placemaking is a holistic approach to the planning, design, “making” and management of public places. It is aimed at making public places that are attractive for people. Tactical transit applies to the technique of using temporary methods to increase the efficiency of transport and enhance passenger experience.
