摘　　要：为了降低共用车道中公共汽车和社会车辆行驶时的相互干扰,本文选取进口道公交停靠站的位置设置为研究对象进行优化.以厦门市3个沿进口道设置的单泊位公交停靠站为例,基于实地数据采集建立了进口道对应的车道宽度、机动车流量、公交车辆与社会车辆速度差异、距离交叉口位置等参数与干扰程度的相关模型,利用该模型预测公交车辆和社会车辆之间的交汇次数误差均低于20%.进而以厦门市的公交停靠站点为实例进行了干扰状态预测,以评价相应进口道运行延误情况,并以干扰最低值作为约束条件,对进口道处设置的公交停靠站提出相应的优化方法.研究验证表明,当机动车道设置宽度在3.5~3.75 m、公交停靠站距离交叉口长度在80~110 m时,干扰现象最不显著.两类车的交通流总量降至500 pcu/h时,车流干扰趋于缓和,且车辆速度差异差小于3 km/h.In order to reduce the mutual interference between buses and other non-transitvehicles in the shared lane,this paper selects the bus stop location of the entrance road as the research object for optimization.Taking 3 single-berth bus stops along the entrance road in Xiamen as an example,this research analyzes the correlation between parameters such as lane width corresponding to the entrance road,motor vehicle flow,speed difference between public vehicles and social vehicles,and distance from the intersection and the degree of interference.Research and verification show that when the width of the motor vehicle lane is 3.5~3.75 m,and the length of the bus stop from the intersection is 80~110 m,the interference phenomenon is the least significant.When the total traffic flow of the two types of vehicles is reduced to 500 pcu/h,the traffic disturbance tends to ease,and the difference in vehicle speed is less than 3 km/h.Taking the bus stops in Xiamen as an example,this research has predicted the interference state to evaluate the operation delay of the corresponding entrance road.The minimum interference value is used as the constraint condition,and the corresponding optimization method is proposed for the bus stops set at the entrance road.
