摘　　要：为描述车辆间信息传递和协同决策过程,表征直行车辆行为特点,提出了基于虚拟车辆的跟驰-换道联合仿真模型,并结合实际交通场景中的数据进行了参数设定和模拟试验。引入右转车辆等价虚拟车辆,向后方直行车辆传递右转车辆汇入信息或者换道信息,使后方直行车辆能够在预测右转车辆汇入过程产生干扰影响的基础上进行行为决策,辅助右转车辆换道行为完成。应用直行车辆的虚拟车辆进行换道决策,若直行车辆决策换道,该直行车辆的虚拟车辆同样会向目标车道的后方车辆传递汇入信息或换道信息,辅助完成换道行为。将旁侧车道上的车辆密度与目标车道上车辆密度的差值作为车辆换道的影响因素,传递了旁侧车道的汇入压力。结果表明:仿真模型产生的轨迹和速度结果能够描述直行车辆在右转车辆干扰下的运行情况和右转车辆干扰信息的传递现象;右转车辆干扰促使更多直行车辆实施换道或者减速避让,增加了交叉口内的交通冲突;当直行流量较低时,右转车流不受控的模式提高了交叉口通行效率,但增加了交通冲突,使交通安全受到一定程度的影响。研究结果为交叉口设计和交通管理提供了理论依据和决策参考。In order to describe the information transmission and collaborative decision-making process among vehicles and characterize the behavior of straight-going vehicles,a joint simulation model of car-following and lane-changing based on virtual vehicles is proposed,and parameter settings and simulation experiments are carried out by combining the data in the actual traffic scene.The equivalent virtual vehicle of right-turning vehicle is introduced to transmit the right-turning vehicle’s convergence information or lane-changing information to the following straight-going vehicle,so that the following straight-going vehicle can make decisions based on the prediction of the interference effects generated by right-turning vehicle,and assist the completion of the lane-changing behavior of the right-turning vehicle.The virtual vehicle of straight-going vehicle is applied to make a lane-changing decision.If the straight-going vehicle makes a decision to change lanes,its virtual vehicle will also transmit merging or lane-changing information to the following vehicle in the target lane,assisting in completing the lane-changing behavior.The difference between the vehicle density on the adjacent lane and the target lane is employed as a factor influencing the vehicle’s lanechanging behavior,and the merging pressure from the adjacent lane is conveyed.The result shows that(1)the trajectory and velocity results can describe the running condition of the straight-going vehicles and the transfer effect of right-turning interference;(2)the interference of right-turning vehicles prompts more straight-going vehicles to change lanes or slow down to avoid collisions,resulting in increased traffic conflicts at intersections;(3)when the direct traffic flow is low,the implementation of uncontrolled right-turning traffic flow scheme improves the efficiency of the intersection,but increases traffic conflicts,so that the traffic safety is affected to a certain extent.The study findings provide theoretical basis and decision reference for in
