A congestion area vehicle source path analysis method based on traffic big data comprises the steps of: constructing a vehicle passing set for each road section through road network information, and acquiring vehicle passing data according to a space range of an area needing to be analyzed and a set time space range; aggregating the vehicle passing data according to license plates to obtain all license plates passing through the area at specified time; acquiring complete track data of the vehicle in a specified time space range; extracting target vehicle tracks, and acquiring each road sectioncorresponding to each track point of a target vehicle; judging whether the vehicle passing set of the road section corresponding to each track of the target vehicles contains the target vehicles or not; judging whether all the target vehicles are analyzed or not; and outputting all road sections and related vehicle passing sets in the road network data according to a preset rule. According to thecongestion area vehicle source path analysis method, by acquiring the track data sources of the rich vehicles, the problem of inaccurate vehicle source path analysis in the congested area in the prior art is solved.
一种基于交通大数据的拥堵区域车辆来源路径分析方法,包括:通过路网信息为每个路段构建过车集合,根据需要分析的区域的空间范围和设置的时间空间范围获取过车数据;将过车数据根据车牌进行聚合,得到在指定时间经过该区域的所有车牌;获取车辆在指定时间空间范围内的完整轨迹数据;提取目标车辆轨迹,获取目标车辆每一个轨迹点所对应的每一个路段;判断目标车辆每一个轨迹所对应的路段的过车集合中是否包含了目标车辆;判断是否已经分析完所有的目标车辆;根据预设规则输出路网数据中的所有路段和相关过车集合。本发明通过获取丰富车辆的轨迹数据来源,解决了现有技术对于拥堵区域车辆来源路径分析不准确的问题。
