Abstract

Abstract: In order to improve traditional field model of easily falling into the queue problem during simulating the evacuation of dense crowds, an improved pedestrian evacuation model in interior space is proposed based on the elite chaos search strategy. The pedestrian mobile income at each moment is calculated in combination with the field value, capacity and average speed, and a field model for pedestrian evacuation is presented. On this basis, the objective optimization function of the minimum evacuation time and minimum queue length is given, and the elite chaos search strategy is used to achieve the above objective function solution, which could enhance the local search ability. The performance between the traditional field model and the improved model are compared in the presented simulation platform. The results show that, under the same environment and number of pedestrians, the improved model could effectively simulate the routing behavior within the visible range.
