基于复杂网络的兰州市公交网络分析

城市交通系统是一个动态的、自组织的、开放的复杂巨系统,交通拥挤等问题严重制约着城市有序、快速、高效地发展。文章基于复杂网络理论,以兰州市为例,运用Pajek软件和L空间法,构造了兰州市公交站点网络,并对公交网络的度、累积度和聚类系数进行了分析。结果表明,兰州市公交站点网络具有无标度特性。

Analysis of Lanzhou Public Transit Network Based on Complex Network

The urban transport system is a dynamic, self-organized, and open complex giant system, the traffic congestion and other problems have seriously restrictad the orderly, rapid and efficient development of the city.Based on complex network theory, and with Lanzhou City as the example, this article used Pajek sofwara and L Space method to construct the Lanzhou public transit station network,and analyzed the degree, cumulative degree and clustering coefficient of public transport network.The results showed that the Lanzhou public transit station network has the scale-free charactaristic.
