Abstract
In terrorist attacks, crowd emotions have a significant impact on the evacuation process. Current researches of crowd emotion modeling are of great importance in formulating emergency plans. However, existing crowd emotional models do not describe the perceptual process in detail. They overlook the audiovisual linkage (AVL), and do not demonstrate head-turning behaviors in evacuation simulation. We propose an AVL-based perception model, which can describe head-turning behaviors in response to dynamic stimuli during emotional events. We also propose a model for calculating crowd emotions and provide a method for representing crowd movements. Compared to existing researches, our method not only improves the perception model but also realizes the influence of perception on agents’ emotions and movements. The results of comparative experiments show that the proposed method can effectively simulate audiovisual linkage phenomena in crowd evacuation during terrorist attacks.
