在中国，培训学校是无处不在的，其中的异质性行人流（由成人和儿童组成）广泛发生在课后时段。在本文中，我们开发了一个细网格元胞元胞自动机模型来描述行人的行为（例如，本研究以一所训练学校为研究对象，探讨课后期间行人的接人行为、搜寻行为、匹配行为、等待行为、引导行为及跟随行为对教室内及教室周围行人行为的影响。为了准确描述异质行人流，（i）设计了一些问卷调查来提取成人和儿童运动的一些特征，（ii）进行了一些视频实验来估计/校准所提出的模型中的一些感兴趣的参数。最后，提出了提高疏散效率和训练学校运行效率的策略。数值结果表明，该模型与实际情况吻合较好，所提出的疏散策略能够提高疏散效率和训练学校的运行效率。研究结果可为学校管理者有效地进行课后行人疏散管理提供参考。
In China, training schools are ubiquitous, where heterogeneous pedestrian flow (which consists of adults and children) widely occurs during the after-class period. In this paper, we develop a fine grid cellular CA model to describe the pedestrian behaviors (e.g., pick-up behavior, searching behavior, matching behavior, waiting behavior, leading behavior, and following behavior) at a training school during the after-class period and explore the effects of the special behaviors on each pedestrian's movement in and around a classroom. To describe the heterogeneous pedestrian flow accurately, (i) some questionnaire surveys are designed to extract some features of adult's and child's movement, and (ii) some video experiments are conducted to estimate/calibrate some parameters of interest in the proposed model. Finally, some strategies are designed to enhance the evacuation efficiency and the operational efficiency of training school. The numerical results indicate that the proposed model can reasonably match with reality, and the proposed strategies can enhance the evacuation efficiency and the operational efficiency of training school. The results can help the administrators to effectively manage the pedestrian evacuation at training school during the after-class period.
