我国少儿培训学校广泛存在,接送期间行人拥挤,存在安全隐患。然而,人们很少对培训学校的人流进行探索。在本文中,我们研究了培训学校教室接送期间的人流。根据培训学校教室的人流特点,我们设计了三个规则来描述成人-儿童的匹配行为,然后提出了一个扩展的CA(元胞自动机)模型来探索每个行人在每个规则下的运动。数值结果表明,每条规则都会影响匹配行为、每个行人的运动、疏散效率和安全隐患。这些结果可以帮助管理人员在接机期间(特别是发生紧急情况时)设计一些有效的培训学校疏散策略。
Children training schools widely exist in China and pedestrian congestion and potential safety hazard occurs during the pickup period. However, little effort has been made to explore the pedestrian flow in a training school. In this paper, we study the pedestrian flow in a training school classroom during the pickup period. Based on the features of the pedestrian flow in training school classrooms, we design three rules to depict the adult-child matching behavior, and then propose an extended CA (cellular automaton) model to explore each pedestrian’s motion under each rule. The numerical results show that each rule influences the matching behavior, each pedestrian’s motion, the evacuation efficiency and the potential safety hazard. These results can help administrators to design some effective evacuation strategies in training school during the pickup period (especially when an emergency occurs).
