The invention discloses a method and a system for guiding vehicle steering at a congested intersection. The method comprises the steps: acquiring the congested distance of a first lane D1 at the intersection; obtaining the driving state of each vehicle within the congestion distance of the first lane D1, wherein the driving state is straight driving or to-be-steered driving; dividing all the to-be-steered vehicles into a plurality of vehicle groups according to the sequence from front to back, wherein each vehicle group comprises at least one to-be-steered vehicle and does not comprise straight vehicles; and generating a first guide path for each to-be-steered vehicle in the odd number of vehicle groups to steer towards the third lane D3 along the normal steering direction, and generating a second guide path for each to-be-steered vehicle in the even number of vehicle groups to change the lane to the second lane D2 and steer towards the fourth lane D4. According to the invention, road resources can be reasonably utilized, and the passing time and waiting time of vehicles at the intersection are shortened.

    一种拥堵路口车辆转向引导方法及系统,包括:获取第一车道D1在路口处的拥堵距离;获取第一车道D1的拥堵距离内的各车辆的行驶状态,行驶状态为直行或待转向;将所有待转向车辆按从前向后的顺序划分为多个车辆组,每个车辆组包括至少一个待转向车辆,且不包括直行车辆;对排在奇数位次的车辆组内的每个待转向车辆生成沿正常转向方向向第三车道D3转向行驶的第一引导路径,对排在偶数位次的车辆组内的每个待转向车辆生成换道至第二车道D2并向第四车道D4转向行驶的第二引导路径。本发明涉及的拥堵路口车辆转向引导方法,能够合理利用道路资源,缩短路口车辆通行时间和等待时间。
