Research on Emergency Evacuation of Crowds Based on the Social Force Model of Panic

Aiming at the problem that it is difficult to quantify the correspondence between human behaviours and emotions in large-scale crowd evacuation in indoor public places during emergencies, a crowd evacuation method based on crowd panic emotions is proposed. Firstly, a crowd social force model based on panic is proposed based on the basic social force model, and the calculation method of individual panic is defined based on the personality model. Then, crowd panic force is added to the original social force model, and the emotion is taken as a major factor affecting crowd movement, so that crowd panic can more realistically respond to the psychological and behavioural characteristics of the crowd and reveal the crowd evacuation movement law. Finally, the relationship between crowd density, exit width, number of exits and crowd evacuation is analysed to study the crowd evacuation problem in the ticket hall, and the results reflect the indoor crowd evacuation law more realistically.
