THE climate crisis, together with other urgent sustainability questions, emphasises the need for a fast and pervasive change within the transport sector. During the last few years, different kinds of experimental initiatives, and the possible role these can play in climate and sustainability transformations, have become a staple of research and policy development contexts. At the same time, questions remain unanswered regarding the strengths and limitations of experimentation, and how experimentation can support transformative change. This anthology brings together insights and reflections from research and policy practice regarding experimentation for sustainable transport. It includes eight individual chapters focusing on themes such as risk-taking, the key features of innovation-producing environments, possible synergies and conflicting interests between actors involved in experimentation, as well as issues related to design-led approaches, public involvement, legitimacy and the possibilities and constraints related to different governance rationales.
