In order to solve urban traffic congestion, environmental pollution and other related problems, major cities across the country have set off a climax of Urban Rapid Rail Transit (URRT) construction. In the URRT industry, the realization of safety risk management, based on the existing safety management, the strengthening of safety awareness, the improvement of safety concept and the optimization of work ideas are conducive to reducing operation risks and improving the level of safety guarantee. On the contrary, if the potential risks in URRT operations are identified and evaluated before the accident occurs, and preventive measures are taken as soon as possible, this proactive “pre-accident prevention” safety management method can truly reduce the risk of accidents. Frequency to achieve the effect of preventing problems before they occur. In view of this, this paper combines the current situation of URRT safety management, starts from the goal of risk assessment, discusses the establishment of risk evaluation index system for different management levels, and establishes an evaluation model based on extension theory, and then provides a new method for URRT risk evaluation. Identifying the risk factors of URRT operation safety through scientific and effective methods, analyzing the safety status of URRT operations, and preventing and controlling operation safety accidents are of great significance to ensuring the safety of URRT operations.
