摘要
采用复杂网络的研究方法,针对长沙市公交网络建立了公交线路、公交换乘和公交停靠站点复杂网络模型,利用这3个网络所产生的拓扑特性指标,如度分布、聚类系数、平均路径长度等,讨论了长沙市公交网络的网络拓扑特性,并证明了长沙市公交网络为小世界网络或无标度网络。
Using the method of complex network,this paper establishes 3 complex network models including bus stations network,bus interchange network and bus lines network in Changsha City Public Transportation.Using indexes of topological properties produced in these models,such as distribution,clustering coefficient and average path length etc,the paper discusses the topological properties of Changsha City Public Transportation Network.It is proved that Changsha City Public Transportation Network is a small-world and scale-free network.
