Book excerpt: This collection of 16 original research chapters by international scholars addresses the complementary roles of transportation and knowledge and their spatial manifestations in modern urban and regional economies. The authors provide research from North America, Europe and Asia. While the studies employ sophisticated methods and theory, there is a strong element of practical applications and policy implications in each chapter as well. This book will be of interest to communities of research and practice in urban and regional economics and planning, regional science and economic geography, transportation research, planning and management and the knowledge economy.
