基于人行横道间距的行人-机动车延误模型

he locations and distances of pedestrian crossings can influence the operational efficiencies of vehicles and pedestrians. Based on 4 conflict scenarios of pedestrian-vehicle system with two crossings, the rules of pedestrian flows calculating at crossings and getting through or yielding at conflict area are proposed, with locations of two crossing as independent variables, pedestrian delay model and vehicle delay model are established respectively, considering the inference delay between pedestrian and vehicle, pedestrian circuitous delay, vehicle following delay, then, pedestrian-vehicle delay model is made up with vehicle load factor. Token a branch road nearby west 2nd ring in Beijing as example and advantage of VISSIM traffic software, 21 simulation scenes at 7 optional location of two crossings focus on the 3 kinds delay values and infer the best location of two crossing.
