This standard establishes a set of performance and functional requirements necessary for enhancing performance, availability, operations, and train protection using a CBTC System.---Revision: There is no change to the words of the scope. The revisions allow for driverless train operation, including automatic people movers.
There are currently no independent standards defining the performance and functional requirements to be satisfied by CBTC systems. This standard will enhance performance, availability, operations, and train protection, and will facilitate new CBTC applications.
