Heterogeneous crowd evacuation model based on influence of hazard sources
In order to study the characteristics of crowd evacuation in dangerous situation,combined with the social force model and considering individual differences,a simulation method of crowd evacuation based on the heterogeneous emotional infection model was proposed.The individuals were differentiated according to the characteristics of individual personality,gender and education level,then the above characteristics were used to calculate the level of panic of different individuals in dangerous situation,and the calculation of human power in the social force model was improved.The results show that when the number of individuals is small,the hazard source will shorten the evacuation time.Different locations of hazard sources al-so have certain influence on the individual evacuation time.The hazard sources near the center of confined space will increase the individual evacuation time,while the hazard sources at other locations will reduce the individual evacuation time.In the face of stressful situation,the men and individuals with higher education levels tend to cope with stressful situation more calm-ly.The research results can provide guidance for pedestrian evacuation in dangerous situation.
