Intelligent Transportation Systems at Highway-Rail Intersections: A Cross-Cutting Study.

摘要

In 1997, the ITS Joint Program Office (JPO) at the Federal Highway Administration commissioned a study to identify projects being conducted in the U.S. that used Intelligent Transportation Systems (ITS) at highway-rail grade crossings, including not only those projects that were Federally-sponsored but state and locally-sponsored ones as well. The study identified seven projects that tested five functions: in-vehicle warning, second train warning, use of crossing blockage information for traveler information and traffic management, four quadrant gates with automatic train stop, and a comprehensive set of technologies called the Intelligent Grade Crossing. The following year, the JPO commissioned a cross-cutting study to examine the commonalities and differences among the seven projects.
