In order to study the influence of subway platform diversion railings on pedestrian evacuation, taking a subway station in Beijing as the research object, the simulation and exploration model of platform level railing setting was constructed by using AnyLogic software based on social force model. Pedestrian parameters were calibrated by field collection and other means, and the passenger flow evacuation phenomenon under different guardrail settings was simulated and analyzed, which is the setting of guide rail for subway station And optimization to provide reference. The results show that: under normal conditions, when the intensity of passenger flow is small, increasing the length of the guide rail will slightly increase the evacuation time of passenger flow; in the case of emergency evacuation, increasing the length of guide rail can effectively reduce the evacuation time of passenger flow and improve the evacuation efficiency of passenger flow.
