IEEE 1474.3-2008 pdf download IEEE Recommended Practice for Communications-Based Train Control (CBTC) System Design and Functional Allocations
1.2 Scope
This recommended practice establishes a preferred system design and functional allocation for CBTCsystems.
1.3 Purpose
The purpose of this recommended practice is to define a preferred CBTC system design/system architectureto achieve the CBTC performance and functional requirements of IEEE Std 1474.1T%-2004, and to allocatefunctions to the major CBTC subsystems.
1.4 Application
The extent to which this recommended practice would be applicable to a specific CBTC installation/projectshould be determined by the authority having jurisdiction.

3. Definitions, acronyms, and abbreviations
3.1 Definitions
For the purposes of this recommended practice, the following terms and definitions apply. See alsoEEE Std 1474.1-2004 for other CBTC-related definitions. The Authoritative Dictionary of IEEE StandardsTerms should be referenced for terms not defined in this clause.
3.1.1 authorized speed: The speed limit at any point along the authorized path of travel up to the targetpoint.
3.1.2 limit of movement protection: A precise location reference point along the authorized path thatmarks the absolute limit to which train movement is protected.
3.1.3 target point: A location reference point along the authorized path of travel to which train movementis currently controlled and supervised.

4.General requirements
4.1 Range of applications
The CBTC system design defined in this recommended practice is intended to be applicable to the fullrange of transit applications, including light rail, heavy rail, and commuter rail transit systems, and shouldalso be applicable to other transit applications such as automated people movers if CBTC is used forautomatic train control (ATC).
The CBTC system design should include the capability for providing ATP, ATO, and ATS functions asdefined in IEEE Std 1474.1-2004.
This recommended practice recognizes that different configurations of CBTC systems are possible.depending on the specific application. For example, a CBTC system may:
