Surface transportation in the United States faces a number of challenges. Despite the fact that the United States has one of the best roadway systems in the world, congestion is increasing and safety remains a serious problem. Congestion takes its toll in lost productivity costing the nation an estimated $40 billion each year. The intelligent transportation systems (ITS) infrastructure allows the surface transportation system to be managed as a seamless, intermodal, multi-jurisdictional entity, and appears to the public as a seamless system. It does so by integrating transportation and management information systems across both modal and jurisdictional lines within a region and, where appropriate, across the country ITS infrastructures have been configured to address the needs of three specific types of users-metropolitan travelers, commercial carriers, and rural travelers.
