Volpe National Transportation Systems Center (U.S.)US Transportation CollectionThis is the second of 4 volumes concerned with developing safety guidelines and specifications for high speed guided ground transportation (HSGGT) collision avoidance and accident survivability. The study formulates collision scenarios to which an HSGGT system may be exposed. Existing U.S. and foreign rules, regulations, standards and practices concerned with either preventing the occurrence of a collision, or mitigating the consequences of a collision are reviewed, together with pertinent practices from other forms of transportation, leading to the formulation of guidelines and specifications for collision avoidance and accident survivability. This volume addressing collision avoidance, describes the features of signal and train control systems used in existing high speed rail, conventional rail and mass transit systems, and other measures to prevent collisions such as prevention of right-of-way intrusions. A description is provided of the interaction between collision avoidance system characteristics and capabilities, and HSGGT system capacity and reliability. Finally, guidelines are developed for collision avoidance systems to be applied to HSGGT systems in the United States.78
