The invention provides a vehicle passing guiding method for an intersection of a vehicle-road cooperation area, and relates to the technical field of vehicle-road cooperation and safety control in an intelligent traffic system. The method comprises the following steps: firstly, acquiring position and speed information of vehicles, detecting the number of vehicles on each lane and slow traffic information in each intersection communication area in a region in real time, and determining a conflict area; counting the passing right of the conflict traffic flow of the motor vehicles; calculating the intersection passing time of the motor vehicle and the passing acceleration of the motor vehicle according to the interaction information between the vehicle-mounted units and the roadside unit and between the vehicle-mounted units; passing deceleration of motor vehicles and non-motor vehicles and passing deceleration of motor vehicles and pedestrians; and finally calculating the safety speed of the motor vehicle following the vehicle. According to the method, the traffic safety problem of vehicle passing at the regional intersection can be effectively relieved, the traffic accident rate is reduced, and the overall regional traffic operation efficiency is improved.

    本发明提供一种车路协同区域交叉口车辆通行引导方法,涉及智能交通系统中车路协同与安全控制技术领域。该方法首先采集车辆的位置和速度信息,实时检测区域内各个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;再统计机动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,计算机动车通过交叉口时间、机动车通行加速度;机动车与非机动车通行减速度及机动车与行人通行减速度;最后计算机动车跟随车辆的安全速度。该方法可以有效缓解区域交叉口车辆通行交通安全问题,减少交通事故率,提升整体区域交通运行效率。
