Reliability Analysis and Comparison of Signaling System Schemes of Train Autonomous Circumambulate System and Communications Based Train Control System
At present,the communication based train control system(CBTC)has been used as the mainstream signaling system for rail transit,while the train autonomous circumambulate system(TACS)has also been gradually put into operation in China.To compare the reliability level of these two signaling systems,this paper performs a reliability analysis for both the TACS system and the CBTC system from the perspective of fault-caused operation delay.It presents the reliability block diagrams of both the TACS and the CBTC system in which faults lead to delays of more than 2 minutes and more than 5 minutes,which are drawn in view of the design architecture of these two signaling systems and the line configuration.Then,it provides an evaluation and comparison of the reliability level under the two system architectures under discussion.Moreover,it proposes improvement measures,which are intended to provide reference for the development and application of the signaling systems for urban rail transit.
