以小学放学时的行人流运动模式作为研究对象,研究该场景中的行人流特征。放学过程中,学校门口的行人流存在行人不均衡分布、行人按一定规则输入输出、行人成对行为、拥堵现象等特征。借助元胞自动机模型,在静态场基础上提出了一个行人流模型,并设计了一种基于下一步距离收益的算法。利用该模型对北京航空航天大学附属小学放学时学校门口的疏散行人流进行仿真,其仿真结果表明行人流输入率和初始分布人数对系统疏散效率有显著影响,平均疏散时间与初始分布人数呈现负相关的关系。
Taking the pedestrian flow movement pattern in primary school as the research object, the pedestrian flow characteristics in this scene are studied. After school, the pedestrian flow in the school entrance is unevenly distributed by pedestrians, and the pedestrians enter and exit according to certain rules, the paired behavior of pedestrians and the phenomenon of congestion. With cellular automata model, a pedestrian flow model based on static field is proposed and an algorithm based on the next distance gain is designed. The model is used to simulate the evacuation of pedestrian flow at the school entrance of Beihang University. The simulation results show that the input rate of pedestrians and the number of initial distribution have a significant impact on the evacuation efficiency of the system. The average evacuation time and the number of initial distributions are negative Related relations.
