Abstract
In this paper, a research method based on characteristic quantity is proposed aiming at the dynamic risk propagation of escalators in regional rail transit hubs. Through the analysis of the risk propagation process of escalator electrical fault, the function relationship between failure rate of escalator and characteristic quantities is obtained. Then AnyLogic is used to model for obtaining the dynamic distribution of passenger flow in the transportation hub, so as to get the consequences severity of the escalator failure. Finally, the Chongqing North Railway Station transportation hub is selected as a case to verify the effectiveness of the method, so it provides effective technical support for the risk control of escalator electrical faults in the transportation hub.
