摘要
[目的]提升乘客服务水平、保障安全是城市轨道交通车站设施布局及运营管理的核心,车站设施的科学设计需研究行人跟随行为的基本特性及其规律。[方法]结合行人轨迹提出行人跟随行为描述模型及其表征参数,设计可控试验模拟城市轨道交通车站单向通道行人跟随行为,采集视频数据提取行人跟随轨迹,深入分析跟随行为发生时行人跟随速度差、跟随时距、横纵向间距等表征参数的特征和规律,研究行人密度、通道宽度、性别和熟悉环境四个因素对单向通道行人跟随行为特性的影响。[结果及结论]行人流密度越低,平均跟随速度差与平均跟随时距均越小;通道宽度对跟随行为表征参数无显著影响;异性间跟随比同性间跟随的表征参数值均较大;不熟悉环境者相对熟悉环境者表征参数值离散程度较大。
[Objective]Improving the service level to the passengers and ensuring safety are the core purpose of the facility layout and operation management of urban rail transit station.To design the station facility scientifically,the basic characteristics and patterns of the pedestrian following behavior need to be studied.[Method] Based on the pedestrian trajectory,a description model of pedestrian following behavior and its characteristic parameters are proposed,and a controllable experiment is designed to simulate the pedestrian following behavior in one way passage of the urban rail transit station.The pedestrian following trajectory is extracted from the collected video data,and the characteristics and patterns of the parameters such as pedestrian following speed difference,time interval,horizontal and longitudinal spacing are deeply analyzed when the following behavior occurs.The effects of the four factors i.e.pedestrian density,passage width,gender and familiarity to the environment on the pedestrian following behavior are studied.[Result & Conclusion] The lower the pedestrian density,the smaller the average following speed difference and the shorter the average following time distance.The passage width has no significant effect on the following behavior characteristic parameters.All the values of the characteristic parameters of the opposite sex are larger than those of the same sex.The values of the characteristic parameters of the pedestrians who are not familiar with the environment are more discrete than those familiar with the environment.
