Abstract: In order to improve emergency evacuation capacity of densely populated underground space, under the background of coupling development of rail transit and underground space, through literature review and case analysis, investigation on evacuation risk identification and safety assessment is carried out. Using Anylogic platform, based on social force model and multi-agent modeling method, simulation and control group experiment are implemented. The experimental results show that the existing evacuation facilities of the station basically meet the 6- minute required evacuation time, where the evacuation starts when population is exceeding 1,800. It also reveals that pedestrian heterogeneity has a negative impact on the formation of evacuation bottleneck, and the zone evacuation strategy helps to alleviate the bottleneck pressure and reduce the risk of congestion as well.

Key words: subway station, pedestrian evacuation, simulation analysis, emergency management
