The invention discloses a lane level positioning method of an intelligent traffic system, which belongs to the technical field of traffic control systems, and specifically comprises the following steps: establishing a road database which stores basic information of an expressway; acquiring real-time information of the highway, wherein the real-time information comprises highway image data, vehicle driving data and a real-time vehicle number; collecting vehicle driving data of any vehicle, comparing the vehicle driving data with a corresponding standard in a traffic control rule, and judging whether traffic jam occurs or not; dividing lanes in the road image data into a plurality of continuous measurement areas, extracting the measurement areas which are judged to have traffic congestion, and matching the measurement areas with the high-precision map to obtain position information of the lanes which are influenced by the traffic congestion; compared with the prior art, the method achieves the lane level positioning of the traffic jam occurrence position.
本发明公开了一种智能交通系统的车道级定位方法,属于交通控制系统技术领域,具体包括以下步骤,建立道路数据库,所述道路数据库存储有高速公路的基本信息;获取高速公路的实时信息,所述的实时信息包括公路图像数据、车辆行驶数据和实时车辆数量;采集任一车辆的车辆行驶数据,将所述车辆行驶数据与交通管制规则中相应的标准进行对比,判断是否发生交通拥堵;将公路图像数据中的车道划分为若干个连续的测量区,提取被判定为发生交通拥堵的测量区并与所述高精度地图进行匹配,获得了被交通拥堵影响的车道的位置信息;相比现有技术,本发明实现了对交通拥堵发生位置的车道级定位。
