Characteristics of Pedestrian Following Behavior in One-way Passage of Urban Rail Transit Stations Based on Pedestrian Trajectory Data

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.
