Congestion and traffic-related pollution are increasingly becoming major issues in towns and cities world-wide. This book deals with carefully selected market and non-market based measures to reduce congestion, and their implementation and effectiveness in tackling the problem. The book features a multi-authored research-based text comprising 12 individual chapters that draw upon relevant case studies. The authors were specifically chosen for their global expertise in terms of the respective Demand Management Tools. Drawing on international case studies, the book details the role played internationally by selected Transport Demand Management (TDM) measures in dealing with both congestion and traffic-related pollution in urban areas, focusing on their relative merits and in particular their effectiveness and the issues surrounding implementation.

A transportation expert makes a provocative case for changing the nation’s approach to highways, offering “bold, innovative thinking on infrastructure” (Rick Geddes, Cornell University). Americans spend hours every day sitting in traffic. And the roads they idle on are often rough and potholed, with exits, tunnels, guardrails, and bridges in terrible disrepair. According to transportation expert Robert Poole, this congestion and deterioration are outcomes of the way America manages its highways. Our twentieth-century model overly politicizes highway investment decisions, short-changing maintenance and often investing in projects whose costs exceed their benefits. In Rethinking America’s Highways, Poole examines how our current model of state-owned highways came about and why it is failing to satisfy its customers. He argues for a new model that treats highways themselves as public utilities—like electricity, telephones, and water supply. If highways were provided commercially, Poole argues, people would pay for highways based on how much they used, and the companies would issue revenue bonds to invest in facilities people were willing to pay for. Arguing for highway investments to be motivated by economic rather than political factors, this book makes a carefully-reasoned and well-documented case for a new approach to highways.

The continued growth in travel along congested urban freeway corridors is exceeding the ability of transportation agencies to provide sufficient roadway capacity in major metropolitan areas with limited public funding for roadway expansion and improvement projects. This book examines the congestion management programs, policies and experiences of other countries that are in the planning stages, have been implemented, or are operating on freeway facilities. The research in this book sought information on how agencies approach highway congestion, actively manage and operate freeway facilities, and plan for and design managed lanes at the system, corridor, and project or facility levels.
