With its creative transformation of a local university car-park into a pedestrian-friendly green space, Metropolia GZM snatched the first-ever MOBILITYACTION award title this past spring. The installation, built at the University of Silesia in Katowice (Poland), has converted part of the campus’ car-dominated surroundings into a public space for students, academics and community members to enjoy. The project engaged professionals from the public transport, cycling, social development, sustainable mobility and urban policy sectors, to craft a prototype that would decrease traffic and increase the space’s usability for students. We sat down with Pawel Jaworski and Aleksandra Hantkiewicz-Lejman, the urban designers behind the award-winning MOBILITYACTION, to discuss their experience building the installation and what they learned.
