TRB Special Report 320: Interregional Travel: A New Perspective for Policy Making examines the demand for and supply of interregional transportation in the United States. Major additions to transportation infrastructure, including high-speed rail, are being considered for some of the country’s most heavily traveled 100- to 500-mile corridors. The availability and use of the automobile, airplane, and train for interregional travel are reviewed along with the rejuvenated intercity bus. U.S. interregional corridors and transportation options are contrasted with those in Japan and Europe, where substantial investments have been made in passenger rail.

Public investments in new, long-lived transportation infrastructure can be risky because of uncertainty about future demand and the development of new technologies and competing transportation services. Decisionmakers in interregional corridors face the added challenge of having to coordinate investments across multiple jurisdictions. The report recommends actions to reduce this uncertainty and create stronger institutional means for developing the country’s interregional corridors.
