The field of mobility biographies research has grown substantially over the past few years. This book assembles an edited volume of work done by leading scholars in the field. It presents critical reflections of previous work that aim to contribute to the conceptual and methodological advancement of the field based on a wide variety of conceptual and methodological approaches. While much research in the field has hitherto relied on statistical analyses of travel behaviour data, this book presents a more balanced mix of quantitative, qualitative and mixed-methods work. Contributing authors represent a variety of backgrounds, including disciplines such as geography, sociology, psychology, transport planning and civil engineering. The book prioritises detailed theoretical and methodological reflections, thus departing from much previous mobility biographies research that has been predominantly empirical and limited in its theoretical and conceptual outlook.
