The Federal Railroad Administration and the Intelligent Transportation Society of America (ITS America) convened a joint Technical Symposium on June 4 and 5, 1997, on the subject "Intelligent Transportation Systems and Their Implications for Railroads." The Symposium was held in conjunction with the ITS America Annual meeting in Washington, DC at the Sheraton Washington Hotel. The Symposium addressed a number of issues of interest to freight, intercity passenger, and commuter railroads, railroad suppliers, states, and ITS suppliers. Some of the issues addressed included the newly developed Highway-Rail Intersection (HRI) User Service #30 architecture for ITS applications, the future direction of communications-based Positive Train Control (PTC) and plans for the implementation of the Nationwide Differential Global Positioning System (NDGPS) network to provide positioning data for PTC. This report encompasses the proceedings of the Symposium.
