The invention provides an intelligent vehicle-road cooperation uncontrolled intersection left-turn vehicle passing guiding method, which relates to the technical field of vehicle-road cooperation and safety control in an intelligent traffic system. The method comprises the following steps of firstly, acquiring position and speed information of a vehicle, detecting the number of vehicles and slow traffic information of each lane in an intersection communication area in real time, and determining a conflict area, counting the passing right of the traffic flow conflicting with the left-turn vehicle, according to information interacted between the vehicle-mounted units and the roadside unit and information interacted between the vehicle-mounted units, calculating the neutral position passing time of the left-turn vehicle and the motor vehicle and the passing acceleration of the left-turn vehicle, the passing acceleration of the left-turn vehicle and the non-motor vehicle and the passing acceleration of the left-turn vehicle and the pedestrian, and finally, calculating the safety speed of the left-turn vehicle following vehicle. The method can effectively solve or relieve the traffic safety problem of left-turn vehicle passing at the uncontrolled intersection, so that the vehicle passes through the intersection in a non-stop state as much as possible, and the passing efficiency and comfort are improved.

    本发明提供一种智能车路协同无控交叉口左转车通行引导方法,涉及智能交通系统中车路协同与安全控制技术领域。该方法首先采集自身车辆的位置和速度信息,实时检测交叉口通信区域内各车道车辆数量与慢行交通信息,确定冲突区域;再统计与左转车冲突车流的通行权;并根据车载单元与路侧单元、车载单元与车载单元之间交互的信息,计算左转车与机动车通行可穿越空档时间、左转车通行加速度;左转车与非机动车通行加速度及左转车与行人通行加速度;最后计算左转车跟随车辆的安全速度。该方法可以有效解决或缓解无控交叉口左转车通行交通安全问题,使车辆尽量在不停车的状态下通过交叉口,从而提升通行效率与舒适性。
