摘要
不同过街方式产生不同类型的行人与机动车冲突与延误,并影响城市道路运行效率.在分析信控路段人行横道处行人过街与机动车运行行为及机非冲突场景的基础上,构建4类行为判定原则,阐述不同过街方式下行人和机动车冲突与延误的产生过程,建立基于过街方式的行人—机动车人均延误模型.以北京市某主干路为对象,仿真一次过街和二次过街条件下延误情形.仿真结果表明,行人二次过街方式能整体上使行人与机动车系统人均延误减小.
Types of pedestrian crossings play important roles in urban traffic,because they bring different conflicts and delays between pedestrians and vehicles.Based on the characteristics and the conflicts of pedestrians and vehicles at signalized road,four behavior rules are established.The inference processes of conflicts and delay between pedestrians and vehicles under different situations of pedestrian crossings are described,the delay model of ped-veh system is developed based on pedestrian crossings.Finally,with the VISSIM software,a simulation case of once and twice pedestrian crossings is studied by an 8-lane road in Beijing.The simulation results show that the twice pedestrian crossing could reduce the average relay of pedestrians and vehicles.
