Abstract

Abstract: In order to study the influence of restricted vision on the process of pedestrian evacuation, a cellular automata model of pedestrian evacuation under restricted vision is established. In the model, the evacuation space is divided into three different areas according to the field of view radius, pedestrians have different ways of moving in different areas. Different income parameters are defined to calculate the pedestrian movement income matrix and determine the target position of the pedestrian in the next time step. An evacuation scene is established to simulate the initial density of different pedestrians, the change of the field of view and the indicator signs in different areas, and the influence of these factors on the evacuation process of pedestrians are analyzed. The simulation results show that the greater the initial density of pedestrians, the longer the evacuation time will be. The larger the field of view radius will help pedestrians evacuate. When the field of view radius increases to a certain value, the effect of pedestrian evacuation is not obvious. There are signs in the room, the evacuation time for pedestrians should be significantly shorter than that without signs, and the evacuation efficiency of pedestrians when there are signs in the blind movement area is higher than that in the visible area of the wall.
