| 摘 要： | 将几个典型城市道路网络作为有向图来分析,这些城市道路网络弧段的BC(betweenness centrality)值的分布呈现一致的规律分布,具有层级性。从总体上来看城市道路网络中大部分等级高的道路具有较高的BC值,大部分等级低的道路具有较低的BC值。

| Abstract: | The spatial distribution of road networks is a fundamental issue in spatial analysis of GIS for Transportation.Betweenness Centrality is extensively used to evaluate the importance of nodes for the analysis of complicated networks.In this paper,six typical urban road networks were selected and transformed to direct graphs for the analysis of betweenness centrality.The results show that the distribution of betweenness centrality shows consistency and has a hierarchical property.The statistical results of bet... |
