Simulation of emergency evacuation in subway station

In this article, the movement rules of human evacuation in subway station were studied in order to provide scientific basis for evacuation design and operational management. A typical subway station was simulated and analyzed on occupant evacuation process under different accident scenes, by setting scene conditions such as people load and accident spot. The amount of exits that can be used under the emergency has a significant impact on the total evacuation time. Oppositely, the variety of emergency location in the platform has little influence on the overall station evacuation when the station hall adopts a distributing design. Another meaningful result is that appropriate usage of each available exit helps to improve evacuation efficiency largely.
