27、troduction provides some background on the rationale used to develop this standard. This informationis meant to aid in the understanding, usage, and applicability of this standard.Conventional signaling/train control systems rely almost exclusively on track circuits to detect the presenceof trains.
28、Information on the status of the track ahead is provided to train operators either through waysidesignals or train-borne cab signals. Ensuring compliance with the signals is achieved through operatingprocedures, wayside automatic train stops, or train-borne supervisory equipment linked to the trains
29、 brakingsystem. These conventional systems are effective in providing train protection, but are not particularlyefficient in maximizing the utilization of the rail transit infrastructure, as a result of a number of fundamentallimitations, specifically, the following:a) The location of trains can onl
30、y be determined to the resolution of the track circuits; if any part of atrack circuit is occupied by a train, the whole track circuit must be assumed to be occupied by thetrain. Track circuits can be made shorter, but each additional track circuit requires additional way-side hardware, so there is
31、an economical and practical limit to the number of track circuits that canbe provided.b) The information that can be provided to a train is limited to a small number of wayside signalaspects or a small number of speed codes in a cab signal system.c) For a wayside signal system with automatic train s
32、tops but without continuous cab signaling,enforcement is intermittent.CBTC systems overcome these fundamental limitations of conventional track circuit-based systems, andtherefore, permit more effective utilization of the transit infrastructure. This is accomplished, for example,by allowing trains t
33、o operate safely at much closer headways, by permitting greater flexibility and greaterprecision in train control, and by providing continuous safe train separation assurance and overspeed protec-tion. Additional benefits of CBTC technology include the economical support of automatic train operation
34、s(both on the mainline and in maintenance yards), improved reliability, and reductions in maintenance coststhrough a reduction in wayside equipment and real-time diagnostic information. The basic characteristics ofa CBTC system include the following:1) Determination of train location, to a high degr
35、ee of precision, independent of track circuits. 2) A geographically continuous train-to-wayside and wayside-to-train data communications network topermit the transfer of significantly more control and status information than is possible with conven-tional systems. 3) Wayside and train-borne vital pr
36、ocessors to process the train status and control data and providecontinuous automatic train protection (ATP). Automatic train operation (ATO) and automatic trainsupervision (ATS) functions can also be provided, as required by the particular application.Although the benefits of CBTC technology are re
37、cognized, there are currently no independent standardsdefining the performance and functional requirements that need to be satisfied by CBTC systems in order torealize enhanced performance, availability, train operational flexibility, and train protection. This standardhas been developed to address
38、this.
