A Safety Assessment Method Based on Risk Analysis of Urban Rail Transit Signaling System in Operation

摘要

The signaling system is a key system to ensure the safety and efficiency of rail transit. The products of signaling systems and their states of usage directly affect the safety and quality of rail transit operations. In the aspect of operations and maintenance, this paper puts forward a safety assessment method based on the risk analysis of operational urban rail transit signaling systems. The authors, through collecting and analyzing the statistics of the operation data, give an instance of application of safety assessment in Shanghai urban rail transit.
