Simulation-Based Model of Emergency Evacuation Guidance in the Metro Stations of China

Abstract

With the development of modern cities, metro are playing an increasingly important role in urban traffic. A biochemical terrorist attack in a metro station can cause many casualties. Therefore, more attention should be paid to metro emergency management. This paper presents a guidance scheme based on an improved empirical formula to optimize emergency evacuation. Additionally, the guidance evacuation model combined the social force model with pedestrian characteristics to study the influence of pedestrian behaviors on guidance evacuation. The experiment results show the following: (1) A guidance scheme based on an improved empirical formula can significantly reduce the casualties and improve the efficiency of evacuation; (2) The guidance evacuation model can be used to find the reasonable guidance locations and the combination of guides. (3) Pedestrian characteristics must be taken into account in the research of the guidance evacuation. Analyzing the behavioral characteristics of pedestrian can provide improvement measures for guidance evacuation. This paper focuses on the simulation experiments of emergency evacuation in metro station, which can provide practical references for developing an efficient and safe emergency evacuation scheme.

Effect of density control in partially observable asymmetric-exit evacuation under guidance: Strategic suggestion under time delay

“…With the development of modern technology especially in the aspect of imaging process, communication networks, and IOT technologies, some evacuation assistants (or equipments) can be adopted in the (computer-aided) evacuation process for providing accurate route or exit information to the evacuees and hence help (guide) them to escape as efficiently as possible. In the related works with guiding behaviors [27][28][29][30][31][32][33][34], Yang et al [27] are the first ones that claimed the necessity of using guides (dynamic leaders) in the evacuation process, whereas the effects of leadership in single-exit rooms were investigated in [28] with limited visible range. The authors in [28] further stated that the guiding behavior may yield a negative effect when too many pedestrians are neighbor to the leader.…”
