A general global wave of public participation is occurring. Students and researchers as well as civil servants, policy-makers, and NGO representatives are encouraged to study, propose, and engage in public participation. New innovative forms of participation are suggested, and experiments in participation are ongoing locally and nationally. Within the transport sector, most studies of participation focus on road infrastructure and other land use changes. However, for other areas within transport, studies are limited and fragmented. Based on this, we see a need for a volume on public participation in transport, aimed at practitioners, students, and researchers, in what are unarguably times of change. The overall aim of the volume is to provide examples of different forms of public participation in transport, which can work as a setting for further analyses and discussions of public participation in transport. Drawing on different cases, eight empirical chapters are presented covering three main themes: grass-roots participation initiatives, participation in unconventional areas, and public participation that throws up unexpected results. In this introductory chapter, we set the scene for later discussions and analyses of public participation in transport. This chapter also provides an overview of the structure and content of the volume.
