IEEE 1474.4-2011

This recommended practice establishes a preferred approach for functional testing of a communicationsbased train control (CBTC) system.

The purpose of this recommended practice is to define a preferred sequence and extent of off-site and onsite functional testing for CBTC systems with the objective of maximizing test efficiency and effectiveness.

New IEEE Standard - Inactive-Reserved. A preferred approach for functional testing of a communications-based train control (CBTC) system, based on the CBTC system design and functional allocations as defined in IEEE Std 1474.3(TM)-2008, is established in this recommended practice.
