摘要
本文以城市公交网络为研究对象,研究城市公交网络的拓扑特性.以南京市公交网络为实例,建立了南京市公交路线与站点网络的数据库,分别构建了基于公交线路的网络模型、基于邻接站点的网络模型、基于换乘站点的网络模型.利用复杂网络理论分析了这三种网络模型的拓扑结构,通过计算网络的静态参数(特征路径长度、度分布、集聚系数等),分析了不同网络的拓扑特性.利用复杂网络理论研究城市公交网络为城市交通规划与发展提出了新的参考建议.
In this paper we study urban public traffic networks and ereat the database of Nanjing urban public bus lines and bus stops. The networks are defined by three different ways： the model based on bus line networks, the model based on bus neighboring networks and the model based on bus change networks. The complex networks theory is applied to analyze the topological structure of the three networks. The character of networks can be obtained by computing networks＇ static parameters, which are the characteristic path length, degree distribution, the clustering coefficient and so on. The complex networks theory provides new advice for urban public traffic plan and development.
