This book adopts a cross-disciplinary approach on the relationships between transport and children's wellbeing by bringing together a series of works by authors from a variety of disciplinary orientations (e.g., urban planning, geography, psychology, transport engineering, and public health). The book's breadth and diversity convey an inclusive view of the complex nature of transport and children's wellbeing. This closing chapter provides a brief overview of and summarizes some important evidence in this field. We point to gaps in knowledge and diagnose difficulties that will provide a roadmap for future research and practice.
