An emotion based simulation framework for complex evacuation scenarios

Abstract

Emotion is a major factor influencing the decision making processes of human. Thus, there is a large difference between evacuation results and the real-life behaviors of crowds when emotion has not been considered in the evacuation model. There are some challenges to generate more realistic simulation results of crowd evacuations area: (1) how to portray the effect of individuals' emotions in evacuation process under various situations; (2) how the third party roles (such as policemen) affect the emotion of the crowd and guide the evacuation. We present an emotion based simulation framework for complex evacuation scenarios. Each individual is modeled as an agent given different emotions, and its emotion has impacts on three aspects: moving speed, the desired goal and path planning. To handle the second challenge, the third party roles can suppress the negative emotions of evacuation crowd and provide suitable exits for the agents around them.
