Abstract: Performance and functional requirements for a communications-based train control (CBTC) system are established in this standard. A CBTC system is a continuous, automatic train control system utilizing high-resolution train location determination, independent of track circuits; continuous, high-capacity, bidirectional train-to-wayside data communications; and train-borne and wayside processors capable of implementing automatic train protection (ATP) functions, as well as optional automatic train operation (ATO) and automatic train supervision (ATS) functions. In addition to CBTC functional requirements, this standard also defines headway criteria, system safety criteria, and system availability criteria for a CBTC system. This standard is applicable to the full range of transit applications including automated people movers.

IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information or the soundness of any judgments contained in its standards. Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document. The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are supplied “AS IS.” The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation, or every ten years for stabilization. When a document is more than five years old and has not been reaffirmed, or more than ten years old and has not been stabilized, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. In publishing and making this document available, the IEEE is not suggesting or rendering professional or other services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the exercise of reasonable care in any given circumstances. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered the official position of IEEE or any of its committees and shall not be considered to be, nor be relied upon as, a formal interpretation of the IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position, explanation, or interpretation of the IEEE. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Recommendations to change the status of a stabilized standard should include a rationale as to why a revision or withdrawal is required.

Introduction [This introduction is not part of IEEE Std 1474.1-2004, IEEE Standard for Communications-Based Train Control (CBTC) Performance and Functional Requirements.] This introduction provides some background on the rationale used to develop this standard. This information is 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 presence of trains. Information on the status of the track ahead is provided to train operators either through wayside signals or train-borne cab signals. Ensuring compliance with the signals is achieved through operating procedures, wayside automatic train stops, or train-borne supervisory equipment linked to the train’s braking system. These conventional systems are effective in providing train protection, but are not particularly efficient in maximizing the utilization of the rail transit infrastructure, as a result of a number of fundamental limitations, specifically, the following: a) b) c) The location of trains can only be determined to the resolution of the track circuits; if any part of a track circuit is occupied by a train, the whole track circuit must be assumed to be occupied by the train. Track circuits can be made shorter, but each additional track circuit requires additional way- side hardware, so there is an economical and practical limit to the number of track circuits that can be provided. The information that can be provided to a train is limited to a small number of wayside signal aspects or a small number of speed codes in a cab signal system. For a wayside signal system with automatic train stops but without continuous cab signaling, enforcement is intermittent. CBTC systems overcome these fundamental limitations of conventional track circuit-based systems, and therefore, permit more effective utilization of the transit infrastructure. This is accomplished, for example, by allowing trains to operate safely at much closer headways, by permitting greater flexibility and greater precision 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 operations (both on the mainline and in maintenance yards), improved reliability, and reductions in maintenance costs through a reduction in wayside equipment and real-time diagnostic information. The basic characteristics of a CBTC system include the following: 1) Determination of train location, to a high degree of precision, independent of track circuits. 2) A geographically continuous train-to-wayside and wayside-to-train data communications network to permit the transfer of significantly more control and status information than is possible with conven- tional systems. 3) Wayside and train-borne vital processors to process the train status and control data and provide continuous automatic train protection (ATP). Automatic train operation (ATO) and automatic train supervision (ATS) functions can also be provided, as required by the particular application. Although the benefits of CBTC technology are recognized, there are currently no independent standards defining the performance and functional requirements that need to be satisfied by CBTC systems in order to realize enhanced performance, availability, train operational flexibility, and train protection. This standard has been developed to address this. iv Copyright © 2005 IEEE. All rights reserved. Authorized licensed use limited to: NORTHERN JIAOTONG UNIVERSITY.
