基于复杂网络的武汉市公交网络特性研究

基于复杂网络的思想,以Gephi软件为分析工具,对武汉市公共汽车交通系统建立了邻近站点、公交线路和公交换乘3种复杂网络,获得了这3种网络的拓扑结构和几个静态几何量参数,并分析了这些网络的拓扑结构特性。结果显示,武汉公交基本可以满足当前需求,但是仍存在分布不均、乘客候车时间过长、个别站点不能通过换乘到达等问题。针对此类问题提出了优化建议。

Characteristics Analysis of Public Bus Transportation Network in Wuhan via Complex Networks

Based on the theory of complex networks and according to the Gephi software,an adja-cent site network,a route network and a public transit network are established for the bus transporta-tion systems in Wuhan,and the topological structures are proposed and several static geometric pa-rameters for these three networks are obtained. Furthermore,topological characteristics which char-acterize these three networks are analysed. According to the data of these three networks,it can find that the bus transportation system can meet the current demands. But there are also some problems which include uneven distribution,too long waiting time and unable to transfer for some individual site. Finally,proposes some suggestions on optimization.
