IEEE Recommended Practice for Communications-Based Train Control (CBTC) System Design and Functional Allocations
Communications-based train control (CBTC) system design and functional allocations from IEEE Std 1474.1-2025 are built upon in the recommended practice 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.
