The invention discloses a lane-level traffic guidance method and system based on an internet of vehicles, and the method comprises the steps: collecting vehicle driving data, and extracting effectivefield information in the vehicle driving data; constructing a basic road network by taking the intersections as nodes and taking road sections among the intersections as connecting lines, wherein theroad section contains lane information; carrying out Link division on road sections in the basic road network to form a divided road network; calculating lane-level travel time according to the driving data and the divided road network; calculating predicted lane-level travel time of each time interval according to the historical travel data and the lane-level travel time; and calculating vehicleshortest travel time between OD points according to the predicted lane-level travel time, and determining the shortest path corresponding to the vehicle shortest travel time as a guidance planning path. According to the invention, the defects of a traditional guidance mode are overcome, and more accurate, safer and more reliable traffic guidance service is provided for travelers.

    本发明公开了一种基于车联网的车道级交通诱导方法及系统,该方法包括:采集车辆行驶数据,并提取所述车辆行驶数据中的有效字段信息;以交叉口为节点,以交叉口间的路段为连线,构建基础路网;所述路段中含有车道信息;对所述基础路网中的路段进行Link划分,形成划分路网;根据所述行驶数据和所述划分路网计算车道级行程时间;根据所述历史行程数据和所述车道级行程时间计算各个时间间隔的预测车道级行程时间;根据所述预测车道级行程时间计算OD点间的车辆最短行程时间,并确定所述车辆最短行程时间对应的最短路径为诱导规划路径。本发明弥补了传统诱导方式存在的不足,为出行者提供更加准确、安全、可靠的交通诱导服务。
