Contemporary society is marked and defined by the ways in which mobile goods, bodies, vehicles, objects, and data are organized, moved and staged. Against the background of the 'mobilities turn' this book articulates a new and emerging research field, namely that of 'mobilities design... '. The book revolves around the following research question: How are design decisions and interventions staging mobilities? It builds upon the 'Staging Mobilities' model (Jensen 2013) in an exploratory inquiry into the problems and potentials of the design of mobilities. The exchange value between mobilities and design research is twofold. To mobilities research this means getting closer to the 'material', and to engage in the creative, exploratory and experimental approaches of the design world which offer new potential for innovative research. Design research, on the other hand, might enter into a fruitful relationship with mobilities research, offering a relational and mobile design thinking and a valuable basis for design reflections around the ubiquitous structures, spaces and systems of mobilities.
