Simulation Study of the Staircase Position to Evacuation Efficiency at the Subway Platform

In order to improve the safety and evacuation efficiency at subway platforms, this paper discusses the applicability of staircase position to evacuation efficiency. First, we summarize the characteristics of passengers at the subway platform. After that, three different position of staircase exits are chosen to be the object of study and a simulation scenario by AnyLogic is built based on the data of a subway platform in Beijing. Finally, we analyze the applicability of three scenarios by the indictor of the number of passengers and time of evacuation process. The simulation results show that, in comparison with three forms of staircase, the staircase exits at the center of the platform have the worst evacuation capacity among the three options. In addition, other two scenario are fit to different volume conditions. Those results can provide some guidance to the facilities design in subway platform.
