To achieve the mobility transition, public space must be reallocated to accommodate sustainable forms of mobility and climate adaptation. However, implementing such projects is challenging due to financial pressures and conflicts.

Tactical urbanism offers a promising solution to this challenge. In Austria, successful pilot projects are already up and running in Graz and Vienna, for example. However, to achieve systemic impact, tactical urbanism must be scaled up to a citywide level. The TACSKA project is therefore developing a concept for the cost-effective scaling of tactical urbanism measures. To this end, criteria are being developed to identify areas with a high need for action and suitability. Additionally, tactical urbanism measures are being categorized to enable the selection of approaches that fit the spatial context. Based on the case study of Graz, a scaling strategy is being developed and exemplary measures are being derived. This creates the foundation for strategic planning that can respond tactically and flexibly to windows of opportunity. Collaborating with the cities of Vienna and Klagenfurt ensures the approach can be transferred to other cities.
