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.
