The invention relates to an urban traffic road network division method, in particular to a novel urban road network dynamic subarea division method. Comprising the following steps of S100, selecting a traffic road network to be researched, and performing road network data acquisition and analysis; s200, according to the collected road network data and the road network topological structure, calculating, selecting and researching the correlation degree of all adjacent intersections in the road network, and obtaining a distance matrix between the intersections according to the correlation degree of all the adjacent intersections; s300, dividing intersections in the road network, determining core intersections, adjacent intersections and noise intersections, and clustering the core intersections, the adjacent intersections and the noise intersections to form class clusters; and S400, repeatedly combining the class clusters separated in the step S300 based on similarity to complete urban road network dynamic subarea division. The method solves the problem that a traditional clustering method is difficult to eliminate abnormal values or has requirements on the shape of a data set and influences the clustering precision.
本发明涉及城市交通路网划分方法,具体是一种新型城市路网动态子区划分方法。包括以下步骤,S100:选择待研究的交通路网,进行路网数据采集及分析;S200:通过采集到的路网数据和路网拓扑结构计算所选择研究路网内部所有相邻交叉口关联度,根据所有相邻交叉口关联度得到交叉口之间的距离矩阵;S300:将路网内交叉口进行划分,确定核心交叉口,临近交叉口以及噪声交叉口,并将其进行聚类,形成一个个类簇;S400:将S300分离出的类簇基于相似度反复合并,完成城市路网动态子区划分。本发明解决了传统聚类方法难以剔除异常值或对数据集形状有要求影响聚类精度的问题。
