    • 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 betweenness centrality illustrates that the majority of road segments in high administrative levels characterize high value while the majority of road segments in low administrative levels have low value in urban road networks.The experimental results show that there is a correlation between the Betweenness Centrality hierarchy in mathematical measure and the administrative levels.
