However, increasing passenger travel and freight movement has led to growing congestion in the nation's transportation system, and projections suggest that this trend is likely to continue. Increased congestion can have a number of negative economic and social effects, including wasting travelers' time and money, impeding efficient movement of freight, and degrading air quality. U.S. transportation policy has generally addressed these negative economic and social effects from the standpoint of individual transportation modes and local government involvement. However, there has been an increased focus on the development of intermodal transportation. Intermodal transportation refers to a system that connects the separate transportation modes--such as mass transit systems, roads, aviation, maritime, and railroads--and allows a passenger to complete a journey using more than one mode. This testimony is based on GAO's prior work on intermodal transportation, especially intermodal ground connections to airports, and addresses (1) the challenges associated with developing and using intermodal capabilities and (2) potential strategies that could help public decision makers improve intermodal capabilities. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-855T/html/GAOREPORTS-GAO-06-855T.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-855T/pdf/GAOREPORTS-GAO-06-855T.pdf GAO-06-855T https://www.govinfo.gov/app/details/GAOREPORTS-GAO-06-855T Testimony GAO-06-855T; Intermodal Transportation: Challenges to and Potential Strategies for Developing Improved Intermodal Capabilities; Federal aid for transportation Ground transportation Intergovernmental relations Strategic planning Transportation industry Airports Intermodal transportation
