This synthesis report will be of interest to department of transportation administrators and transportation planning, right-of-way, economic development, and environmental planning staffs, as well as to the consultants that work with them. It would also appeal to regional and local government officials and staff, as well as to the private sector. It summarizes information about corridor management policies and programs at the federal, state, and local levels. An effort was made to select a diversity of methods and programs for the broadest treatment of the subject. The synthesis focuses more on roadway corridors than on transit or greenway corridors, but much of the information provided is relevant to any corridor management effort. This report examines state policies and programs, techniques applied, and coordination issues. A series of case studies provides more detailed study. This report of the Transportation Research Board documents successful partnerships. It presents examples of transportation agencies working together, proactively, with local governments and other stakeholders to achieve more cost effective and comprehensive solutions to transportation problems.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 337: Cooperative Agreements for Corridor Management examines the current state of practice in developing and implementing cooperative agreements for corridor management, elements of such agreements, and successful practices or lessons learned. The report focuses on cooperative agreements between two or more government agencies or between public and private entities that address land use and transportation linkages.

This synthesis will be of interest to state and local traffic engineers, transportation planners, transit operators, law enforcement officials, public information agencies, and others responsible for the transportation elements of freeway corridors. Information is provided on the policies and procedures for freeway corridor management, and descriptions of a number of techniques and practices are presented. Traffic growth and increasing congestion on urban freeways require a comprehensive approach toward managing the complex elements of freeway operations. This report of the Transportation Research Board provides information on freeway corridor management strategies, the components of management, examples of effective applications of the strategies, and benefits of freeway corridor management. The management techniques that are discussed include freeway surveillance and control; corridor street surveillance and control; high-occupancy vehicle facilities and incentives; police enforcement and traffic control; hazardous material and other truck traffic restrictions; alternative route planning; motorist assistance patrols; motorist information techniques; and traffic management for recurrent congestion, for incidents, for special events, and for work zones.

Trade and transport corridors—major routes that facilitate the movement of people and goods between regions and between countries—have existed for millennia. They enable regions and countries to offer high-capacity transport systems and services that reduce trade and transport costs by creating economies of scale. Regional corridors are particularly important to landlocked countries, often providing the only overland routes to regional and international markets. Despite a long and complex history, guidance is often lacking on how to design, determine the components to include, and analyze the impact of corridor projects. The Trade and Transport Corridor Management Toolkit fills this void. The Toolkit synthesizes the experiences of the World Bank and other development agencies in assessing, designing, implementing, and evaluating the impact of trade and transport corridor projects. It saves project developers the task of looking for the best available tools and ensures greater consistency to facilitate comparison and benchmarking. The Toolkit will also be of immense value to policy makers in provincial and national governments as well as regional economic institutions, for several reasons: • Corridors affect the space economy of countries; they are best developed with clear estimates of the spatial impacts that can be expected. • A corridor system has multiple components, including infrastructure (roads, railways, ports), transport and logistics services, and regulations; it is important to appreciate the linkages between them, particularly as the overall performance of a corridor is determined by the weakest component. • Many parties with varying interests and motivations have a stake in corridor development. The Toolkit argues for their full participation in corridor development processes and operations. The best functioning modern corridors in the world did not happen by accident; they are often the results of coordinated development and cooperation over many years. The general principles outlined in this Toolkit should help project teams, government officials, logistics service providers, and the trade community to better appreciate both the importance of good corridor project design and the challenges of, and possibilities from, improving corridor performance.
