The invention provides an urban traffic operation state feature calculation method based on floating car data, and is used for solving the problem of limitation of urban traffic operation state feature calculation in the prior art. The method comprises the following steps: firstly, preprocessing acquired floating car data, then carrying out mesh generation on a corresponding map, extracting node pairs to construct a node relationship model, and finally, carrying out traffic operation state feature calculation. According to the invention, regional traffic state feature calculation can be realized only through floating car data without depending on a GIS electronic map; input data and output results can be stored in a database and can be called at any time conveniently and quickly; a road network model depending on node pairs is obtained, geographic features of a road network are described, the geographic features can be stored in the database, repeated calculation is not needed, the method is not limited by time, the real-time traffic operation state can be obtained, and the operation states of each month, each week, each day, each hour and each 15 minutes can also be obtained.

    本发明提供了一种基于浮动车数据的城市交通运行状态特征计算方法,用于解决现有技术中对城市交通运行状态特征计算的局限性问题。所述方法为,首先对采集的浮动车数据进行预处理,再对相应的地图进行网格划分,并提取节点对构建节点关系模型,最后进行交通运行状态特征计算。本发明仅需要浮动车数据而不依靠GIS电子地图即可实现区域交通状态特征计算;输入数据及输出结果可以保存在数据库中,可以随时调用,方便快捷;求得依靠节点对的路网模型,对路网的地理特征进行刻画,该地理特征可以储存在数据库中,不需要重复计算,且不受时间制约,可以求得实时的交通运行状态,也可以求得每月、周、日、小时、15分钟的交通运行状态。
