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. This standard establishes a set of performance and functional requirements necessary for enhancing performance, availability, operations, and train protection using a CBTC System.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P1474.2
IEEE Draft Standard for User Interface Requirements in Communications-Based Train Control (CBTC) Systems
User interface requirements for communications-based train control (CBTC) subsystems are established in this standard.
P1474.3
IEEE Draft Recommended Practice for Communications-Based Train Control (CBTC) System Design and Functional Allocations
This recommended practice for communications-based train control (CBTC) system design and functional allocations builds on IEEE Std 1474.1 by decomposing each identified automatic train protection, automatic train operation and automatic train supervision function to a level where each subfunction can be allocated to one of the CBTC subsystems.
P1474.4
Recommended Practice for Functional Testing of a Communications-Based Train Control (CBTC) System
This recommended practice establishes an approach for functional testing of a communications-based train control (CBTC) system that maximizes test efficiency and effectiveness.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
