The invention discloses a vehicle traffic priority control method based on high-precision positioning. The method comprises steps that a vehicle priority control system of a city or region is built where a vehicle is located in advance based on high-precision positioning data, and the system comprises the high-precision geographic information and vehicle information data; the real-time speed and position information of a vehicle is collected in real time, a lane where the vehicle is located and the distance information are recognized, and lane-level path planning and space-time trajectory prediction are carried out; and then, through fitting comparison of the actual driving track and the predicted space-time track, the lane-level driving route is adjusted in time, and when necessary, through cooperative linkage of lane-borrowing driving and upstream and downstream traffic control points, a priority control release scheme and a transition scheme are selected, so efficient and accurate priority management and control of vehicles are realized. The method has advantages of being high in control precision and flexible in control strategy, the passing time of vehicles is controllable andpredictable, traffic passing efficiency can be improved in multiple aspects and multiple levels, and passing safety is guaranteed.
一种基于高精度定位的车辆交通优先控制方法,该方法基于高精度定位数据,预先建立车辆所在城市或区域的车辆优先控制系统,该系统包含高精度地理信息和车辆信息数据;通过实时采集车辆的实时速度、位置信息,识别所在车道、距离信息,进行车道级路径规划和时空轨迹预测;再通过实际行驶轨迹和预测时空轨迹的拟合比对,及时调整车道级行进路线,必要时通过借道行驶、上下游交通控制点的协同联动,选择优先控制放行方案和过渡方案,实现车辆的高效、精准优先管控。本发明所述的方法具有控制精度高、控制策略灵活的优点,使车辆的通行时间可控、可预测,能够在多个方面、多个层次提高交通通行效率,保障通行安全。
