The invention provides a method and a system for analyzing and identifying an urban traffic corridor based on a signaling track and big data. The method and the system are realized based on mobile phone signaling data reported by a user. In the specific implementation process, OD chain data of a user is obtained by processing signaling data, complete road section information can be obtained afterthe OD chain data is matched with a road network, the similarity of road sections is determined on the basis of the editing distance, track section clustering is conducted on the basis of the editingdistance, and a center track section is continuously constructed through resetting and updating of the mass center; and finally, combining the key sub-paths according to the relationship between the road sections and the intersections to obtain candidate road sections. And different flow thresholds can be preset by combining the traffic and transportation standards of each city, and the paths reaching the threshold standards are used as traffic corridors. According to the invention, data of motor vehicle traffic corridors, bus corridors, subway corridors and comprehensive traffic corridors canbe obtained through signaling analysis of different crowds.

    本发明提供一种基于信令轨迹及大数据分析识别城市交通走廊的方法与系统,基于用户上报的手机信令数据实现。在具体的实现过程中,通过对信令数据的处理,获得用户的OD链数据,在与路网匹配后可得到完整的路段信息,本发明在基于编辑距离的基础上确定路段的相似度,并基于编辑距离进行轨迹段聚类,通过质心的重置更新不断构造中心轨迹段。最后通过路段与交叉口的关系合并关键的子路径得到候选的路段。结合每个城市的交通运输标准,可预设不同的流量阈值,对于达到阈值标准的路径作为交通走廊。本发明可通过对不同人群的信令分析,获得机动车交通走廊、公交走廊、地铁走廊以及综合交通走廊数据。
