A Study of Tolerant Waiting Time of Pedestrians at Signalized Intersections in Beijing

Pedestrians are an important part of traffic at the signalized intersections.At present,the planning and design of the signalized intersections give priority to efficiency of the vehicles.In order to ensure the efficiency of the vehi-cles,many pedestrians crossing environments have been destroyed in Beijing."Chinese style of pedestrian crossing" was invented.Based on the characteristics of the current traffic in Beijing,this study focuses on the pedestrians who arrive at the signalized intersection crosswalk waiting area during the red light.A total of 9 554 pedestrians'waiting time were col-lected by both video survey and manual survey under the different conditions.This study develops a Cox hazard-based model of pedestrians'tolerant waiting time at signalized intersections.The result shows that the maximum tolerant waiting time of pedestrians is 52.88 s.The temperature,gender,age,travel time,red light time,traffic volume,length of cross-walks have great impacts on the pedestrians'tolerant waiting time,however land usage have no significant impacts on it.
