基于复杂网络的中小城市公交网络特性分析

The Characteristic Analysis of Transit Network in Small Cities Based on the Complex Network Theory

为分析我国中小城市公交网络的拓扑结构特性,促进中小城市公共交通的健康发展.以中小城市公交网络为研究对象,基于L空间和P空间方法建立公交站点网络和公交换乘网络模型,利用Matlab统计网络的平均路径长度、聚集系数、度及度分布,对黄石市公交网络进行实证分析.结果显示,黄石市公交网络在演化过程中,既有优先增长机制,又具有随机连接因子.另外,通过对比分析黄石市与大城市公交网络的静态特性统计值,总结了中小城市公交网络特性中的不足之处,并针对这些问题提出了参考建议.

To analyze the topological characteristics of transit networks of small cities in China and to promote the healthy development of public transportation in small cities,models of transit station network and transfer network are established based on Space Land Space P methods based on the transit networks of small cities.An empirical analysis of the transit network in Huangshi city is conducted by calculating the average path length,clustering coefficient,degree and degree distribution of statistics networks in MATLAB software.The results show that the transit network of Huangshi city has both the preferential growth mechanism and random growth factor in the process of evolution.The deficiencies of transit networks in small cities are summarized by comparing the static statistical characteristics of Huangshi city with other big cities in China,and some reference suggestions are proposed to mitigate these dificiencies.
