Book excerpt: This book discusses the role of public-private partnerships (PPPs) in global transportation infrastructure. Seen as a way to provide vital services in an era of shrinking government budgets, public-private partnerships have become an increasingly important part of travel infrastructure worldwide. This book describes and analyzes the structure of various models of PPPs in various countries, evaluating their effectiveness, and drawing policy implications for future use. Written by leading international researchers and practitioners in the transportation field, each chapter is a case study on the adoption, implementation, and outcome of transportation services in different municipalities. Taken together, these diverse case studies provide an integrated framework for evaluating and using PPPs. Providing rigorous empirical analysis of PPPs in transportation, this volume will be of interest to researchers in public administration, political science, and economics as well as practitioners and policymakers involved in establishing and monitoring PPPs in transportation.
