Abstract: The general metro evacuation calculation is mostly about analysis of the capacity of evacuation facilities. However, the factors, i.e. metro station construction form and the diversity of the height of the station to the platform, the complexity of the passenger flow, etc., affecting the evacuation of metro passenger flow and their influencing degrees are unclear. Hence, further analysis should be carried out by combining simulation software. Based on the BIM environment and Pathfinder simulation software, the evacuation of passengers at the same lifting height under different passenger flows of stations with different architectural forms and the evacuation of passengers at different lifting heights under same passenger flow of stations with same architectural form are studied when the evacuation time can be guaranteed. The simulation data and analysis results show that the station architectural form has little influence on the evacuation efficiency of the platform passenger flow; the evacuation effect decreases first and then increases with the increase of the height of the transit facilities, and the demarcation point is at 19 m. Meanwhile, the emergence of congestion during the evacuation process will cause a large deviation between the simulation results and the theoretical calculation results. Therefore, the redundancy of evacuation facilities should be considered to some extent.
