The invention relates to the technical field of traffic big data assessment, in particular to a traffic big data assessment model construction method. The method comprises the following steps that vehicle traffic data of a target area is collected for a traffic management system, road track point matching is carried out, and vehicle track point matching data is obtained; performing road section vehicle travel analysis on the vehicle track point matching data to obtain a road section travel set; performing road section state analysis on the road section travel set to obtain road section state data; performing dynamic road section state deduction analysis on the road section state data to obtain a dynamic road section state matrix; generating a zone state road network diagram according to the dynamic road section state matrix to obtain the zone state road network diagram; and performing adjacent road section association analysis on the road network diagram with the state to obtain a road section association matrix. According to the method, accurate evaluation of the global performance of the road network under traffic big data is realized through evaluation model construction steps and processes of data driving, multilayer analysis, dynamic description, topological association and dimension expansion.

    本发明涉及交通大数据评估技术领域,尤其涉及一种交通大数据的评估模型构建方法。所述方法包括以下步骤:对交通管理系统进行目标区域的车辆交通数据采集并进行路段轨迹点匹配,得到车辆轨迹点匹配数据;对车辆轨迹点匹配数据进行路段车辆行程分析,得到路段行程集;对路段行程集进行路段状态分析,得到路段状态数据;对路段状态数据进行动态路段状态推演分析,得到动态路段状态矩阵;根据动态路段状态矩阵进行带状态路网图生成,得到带状态路网图;对带状态路网图进行相邻路段关联分析,得到路段关联矩阵。本发明通过数据驱动、多层分析、动态刻画、拓扑关联和维度拓展的评估模型构建步骤过程,实现了交通大数据下的路网全局性能的精准评估。
