摘要: 城市公共交通网络是由公交线路和停靠站点构成的复杂网络,网络的几何性质对站点间的可达性具有重要影响。本文采用Space P法对合肥市公共交通网络进行拓扑,并计算分析了节点的度、群集系数、节点介数以及平均路径长度4个指标及其分布规律。结果表明,合肥市公共交通网络具有明显的小世界网络特性。采用系统聚类分析方法将公交站点归类,并通过比较各类站点对公交网络平均换乘次数的影响,确定了各类站点的相对重要性。站点的聚类结果可为公共交通网络管理、规划方案的制定提供参考。

Abstract: Urban public transit system can be regarded as a complex network consisting of stops and bus lines. The geometric characteristics of the network have close relationship with the accessibility of the stops. The Space P network of the Hefei transit network is established. And the value and distribution of the network’s degree, clustering coefficient, betweenness centrality, and average path length are computed and analyzed. The result indicates that the Hefei transit network has the characteristics of small-world networks. All stops are classified by systematic cluster analysis. The relative importance of the classified stops is determined based on the influence of the different classification on the average transfer number. The results can provide reference for the transit management and planning.

Key words: traffic engineering, public transit network, complex network, systematic cluster analysis
