A Crowd Evacuation Method Integrate into the Emotion Model

Aiming at the problem of high density crowd evacuation, a crowd evacuation algorithm based on the improved social force was proposed. Firstly, the algorithm is an improvement to the traditional social force model of the problem with all pedestrians variation are same, on the basis of the group form, the optimal speed was set to constrain the speed of the members in the group. Secondly, according to the theory of personality, emotion model was established for all pedestrians, the pedestrian's emotion state was divided into positive emotions and negative emotions, establishing the mechanism of emotion influence through individual influence. Finally, the command strategy was obtained by the individual emotion distribution in the process of crowd evacuation. The simulation results showed that the improved social force model eliminates the turbulence in the narrow channel, pedestrians accelerating or keeping the critical speed was avoided, and provide a basis for when to join the command strategy.
