Urban spaces are confronted with diverse competing uses. There is high development pressure on inner-city land, especially in growing municipalities. At the centre of the planning model of triple inner urban development is the question of how mobility, green and open spaces and building can be developed together in a qualified manner in order to achieve high quality of life for all city residents. This planning model thus extends the existing planning model of dual inner urban development to include the spatial dimension of mobility. Traffic areas, seen as sealed areas of potential, are of great importance when dealing with current challenges. Mobility and the (re)designing road space is crucial for land use and have an influence on climate protection and adaptation, on the provision of recreational areas, the promotion of urban nature, air quality as well as noise pollution, and thus on human health.
