摘要
为研究聚集活动中的行人在移动过程中所表现出的行为特征对人群整体移动过程的影响,通过实验观察与计算机仿真模拟的方法对人员移动进行研究。通过对实验视频的观察分析,在CTM模型基础上建立考虑人员跟随行为与保持距离行为特性的移动模型,并在简单无障碍和复杂多障碍的场景进行仿真实验。结果表明:模型能有效地描述行人的运动特征,而且拥挤程度和行人间排斥作用越大时行人移动越慢,整个疏散过程花费时间越长;障碍物的存在会影响人群在出口处的“成拱现象”,对理解人员的运动规律和防止拥挤踩踏事故具有一定理论和现实意义。
In order to study the influence of the behavioral characteristics of pedestrian during the movement process in assembly activities on the overall movement process of the crowd,the personnel movement was studied by the experimental observation and computer simulation.By observing and analyzing the experimental videos,a movement model considering the characteristics of personnel following behavior and keeping distance behavior was established on the basis of the CTM model,and the simulation experiments were conducted in the simple barrier-free and complex multi-obstacle scenarios.The results showed that the model could effectively describe the movement characteristics of pedestrian,and the greater the crowdedness degree and the repulsive effect between pedestrian,the slower the movement of pedestrian,and the longer the overall evacuation time.The existence of obstacles would affect the“arching phenomenon”of crowd at the exit.The results have certain theoretical and practical significance for understanding the movement laws of personnel and preventing the crowded stampede accidents.
