摘要: 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。

Abstract: Based on the pedestrian flow patterns of primary students, this paper investigates the features of pedestrian flow under the rules of the certain scenario. During the primary students' evacuation process after school, various pedestrian behavior takes place, including pedestrian uneven distribution, pedestrian's input and output according to certain rules, paired phenomena and congestion phenomena. This paper uses the cellular automaton model and the static floor field to propose a pedestrian flow model and design an algorithm to calculate distance earnings of next move. This method is applied to simulate the evacuation behavior of pedestrians at the gate of Affiliated Primary School to Beihang University after school. The simulation results indicate that the input rate and the number of pedestrians at the initial stage have significant impacts on the evacuation efficiency and that there is a negative correlation between the average evacuation time and the initial number of pedestrians.

Key words: pedestrian flow, cellular automaton, modeling, simulation, static floor field
