Abstract: In order to ensure the efficiency and safety of pedestrian emergency evacuation in subway stations during peak hours in case of sudden accidents, the existing evacuation scheme was optimized. Firstly, the characteristics of pedestrian evacuation in subway stations during peak hours were analyzed, the necessity of adding evacuation guidance during peak hours was clarified, and the common bottleneck congestion points in evacuation were summarized. Subsequently, evacuation guidance measures were designed for the location of each bottleneck congestion point, and the existing evacuation plan and the optimization plan after adding evacuation guidance were designed respectively. Finally, two kinds of evacuation schemes were simulated by Anylogic software, and multiple evacuation evaluation indexes were compared and analyzed to verify the effectiveness of the optimization scheme. The research shows that the existing evacuation scheme can complete the evacuation on time during off peak hours, but its total evacuation time during peak hours exceeds the 360 seconds required by subway safety evacuation regulations. While the total evacuation time of the optimization scheme during the peak hours is 352 seconds and the longest passing time of the gate is 278 seconds, which are both better than those of the existing evacuation schemes. The research results can provide reference for the specific design of evacuation guidance in the evacuation plan of subway stations during peak hours.
