Abstract: The turn-back capacity has always been a bottleneck in the operational capacity of urban rail transit. This paper analyzes the turn-back process of a typical station and proposes a plan of subdividing and optimizing turnout control based on the new generation of train-to-train communication signaling control system to improve the turn-back capacity. Through this method, the turn-back capacity can be increased by more than 25% compared with CBTC system, making the operation interval of urban rail transit less than 90 seconds.
