Based on the work of the STELLA (Sustainable Transport in Europe and Links and Liaisons with America) Focus Group 3, this volume brings together leading transport academics to discuss society behaviour and public/private transport. Theoretical and empirical research from across North America and Europe form the basis of this book, which is composed of twelve chapters that fall into four logical sections. Chapters in the first section provide a contextual overview and survey trends in mobility behaviour and prospects of sustainable transport in the two continents. Chapters in the second section provide comparative assessments of difficulties posed by contemporary transport systems for three particular user groups (low-income, female, and elderly), interventions indicated, and research needed. The third set of chapters survey recent developments in behavioural modelling that lend themselves to the study of the constellation of issues concerning Stella Focus Group 3. The remaining chapters of the book address critical issues of equity and policy implementation.
