Thinking and Practice of Urban Rail Transit Safety Resilience

Objective As an important transportation infrastructure, urban rail transit is crucial to ensure safe and orderly operation of the city. In order to cope with the safety challenge faced by urban rail transit system, it is necessary to discuss the strategy of improving the safety resilience of the system. Method The relevant safety definition and resilience expression are introduced, and the connotation of the concept of safety resilience in urban rail transit system is put forward. Based on the construction and operation practice of Shanghai rail transit as well as specific cases, the strategy of improving the safety resilience of urban rail transit system is proposed from three aspects, i.e. tunnel structure safety, facility reliability and system collaboration. Result & Conclusion It is proposed that strengthening the intrinsic and system safety is the core task, and consolidating the safety cornerstone of tunnel structure, intensifying the reliability of key facilities and equipment, and enhancing the matching and coordination between systems are the key measures to continuously improve the safety resilience of urban rail transit system.
