The invention relates to a vehicle running track extraction method, thereby solving a technical problem that the urban driving vehicle running path is difficult to determine. The method comprises thefollowing steps: acquiring vehicle passing data of all electronic polices and checkpoints on a certain day; determining that adjacent detection points of a certain vehicle can be directly connected toform an effective path; under the condition that the adjacent detection points cannot be directly connected, extracting all possible effective paths between the connected detection points; determining consumed time of different paths based on the extracted effective paths and the operation data information of different road sections of each time period of the Internet; comparing the consumed timeof the possible path with the time difference of the adjacent detection points, and determining an optimal vehicle driving path set; and determining an optimal driving path by adopting a fuzzy comprehensive evaluation method. Key data support can be provided for road section traffic volume distribution, traffic travel induction and road network planning in any time period of an urban road trafficnetwork, the traffic cost can be reduced, the travel efficiency can be improved, and the method has the broad application prospect.
本发明的一种车辆运行轨迹提取方法,可解决城区驾驶车辆行驶路径难确定的技术问题。采用以下步骤:获取某一天的所有电子警察、卡口的过车数据;确定某辆车的相邻检测点位可直接相连形成有效路径;在相邻检测点位不能直接相连情况下,提取相连检测点之间所有可能的有效路径;基于提取的有效路径和互联网的各个时段不同路段的运行数据信息,确定不同路径的耗时;将可能路径的耗时与相邻检测点的时间差值进行对比,确定最优的车辆行驶路径集;采用模糊综合评价法确定最优的行驶路径。本发明可为城区道路交通网络任意时段内路段交通量分配、交通出行诱导以及路网规划提供关键的数据支撑,可降低通行成本,提高出行效率,具有广阔的应用前景。
