Simulation method and system for intersection turning vehicle to converge into straight lane
The invention discloses a simulation method and system for intersection turning vehicles to converge into a straight lane, and belongs to the technical field of intelligent traffic. The method comprises the steps: determining a confluence point of a target vehicle on a target lane through obtaining the data of the target vehicle at an intersection and the data of each vehicle in the target lane where the target vehicle is about to converge; and correspondingly drawing up a virtual target vehicle, determining a confluence gap of the target vehicle in the target lane, judging whether the target vehicle converges into the target lane in the confluence gap or not by using the virtual target vehicle, and then obtaining the distance between the target vehicle and the virtual target vehicle in real time until the vehicle crosses the confluence point, thereby completing the confluence. According to the invention, the behavior that the target vehicle converges into the target lane is smoother and more reasonable, the turning vehicle merge information is transmitted as soon as possible, the driving behavior adjustment of each vehicle in the target lane is assisted, and the actual condition of the exit lane at the intersection is judged in real time when the confluence conflict condition of the turning vehicles occurs.
本发明公开了一种交叉口转弯车辆汇入直行车道仿真方法及系统，属于智能交通技术领域，通过获取处于交叉口的目标车辆数据、以及目标车辆即将汇入的目标车道中各个车辆数据，确定目标车辆在目标车道上的合流点，并对应拟定虚拟目标车辆，确定目标车辆在目标车道的合流间隙，并利用虚拟目标车辆判断目标车辆在合流间隙汇入目标车道是否发生合流冲突，随后实时获取目标车辆和虚拟目标车辆距离，直至车辆越过合流点，完成合流。通过本发明使得目标车辆汇入目标车道的行为更加顺畅合理，并且及早传递转弯车辆汇入信息，协助目标车道各车辆的行驶行为调整，实时判断当存在转弯车辆的合流冲突情况发生时，交叉口出口道的实际情况。
