Abstract

This paper analyzes the characteristics of emotion state and group behavior in the evacuation process. During the emergency evacuation, emotion state and group behavior are interacting with each other, and indivisible. The emotion spread model with the effect of group behavior, and the leader-follower model with the effect of emotion state are proposed. On this basis, exit choice strategies with the effect of emotion state and group behavior are proposed. Fusing emotion spread model, leader-follower model and exit choice strategies into a cellular automata (CA)-based pedestrian simulation model, we simulate the evacuation process in a multi-exit case. Simulation results indicate that panic emotion and group behavior are two negative influence factors for pedestrian evacuation. Compared with panic emotion or group behavior only, pedestrian evacuation efficiency with the effects of both is lower.
