Evaluation of Alternative Detection Technologies for Trains and Highway Vehicles at Highway Rail Intersections;Final rept. Oct 99-Jul 01

摘要

Under sponsorship from the Federal Railroad Administration (FRA), the Transportation Technology Center, Inc. (TTCI) and the John A. Volpe National Transportation Systems Center (Volpe Center) evaluated five technologies for their ability to detect trains and/or highway vehicles approaching and occupying highway railroad intersections (HRI). TTCI conducted tests on the performance of these technologies during October and November 1999 at the FRA's Transportation Technology Center in Pueblo, Colorado, USA. The categories of evaluation include train approach detection, train island detection, static highway vehicle detection and dynamic highway vehicle detection. Intelligent Transportation System (ITS) information was also collected to evaluate the technologies ability to determine train direction, train speed and train length.
