Simulation Analysis of Safe Evacuation in a Railway Tunnel Emergency Rescue Station

This paper in order to improve the design parameters of evacuation passageway of emergency rescue stations in long railway tunnel based on the principle of the minimum evacuation time and best evacuation route, and study the impact of evacuation speed on evacuation time due to personnel panic. The evacuation time in different combinations of parameters of spacing and width of evacuation passageway and width of platform is calculated by Pathfinder simulation software considering characteristics, speed and path of evacuation. The simulation takes the fire accident of 18 marshalled passenger trains in an emergency rescue station in tunnel as an example. The study results show that: 1) Due to the panic mentality, the evacuation speed will increase, so the population flow rate will increase and the evacuation time will be shorter. 2) The optimal distance for the evacuation passageway of the emergency rescue station is 50m, the optimal width is 3.5m, and the platform width should not be less than 2.5m.
