Book excerpt: Bringing together the leading authors currently working at the intersection of social science and transport science, this volume provides a companion to the well-established and extensive international Transport and Society series. Each chapter, and the volume as a whole, offers closer and richer consideration of the issues, practices and structures of multiple mobilities which shape the current world but which have typically been overlooked or minimised. What this approach seeks to do is not only draw attention to many new areas of research and investigation relating to mobile lives, but also to point to new theories and methods by which such lives have to be researched and examined. Such new theories and methods are relevant both to rethinking 'transport' studies as such but are also recasting 'societal' studies as 'transport' so that it comes out of the ghetto and enters mainstream social science.
