| 摘 要： | 对城市公共交通网络结构的深入了解有助于更好的规划、设计与评价公交系统.运用复杂网络的研究方法对我国5个大城市的公交网络结构进行实证分析,统计了路长、群聚系数、度分布等物理量.结果表明网络结构近似于随机网络,不同于国外城市的无标度网络结构.通过分析各个统计量在城市交通中的实际意义,分析了可能造成这种差异的原因.

| Abstract: | To make a better planning,design and evaluation for the public transport systems,it is necessary to make more profound studies for the structure of urban transit networks.The authors have analyzed statistical parameters including path-length,clustering coefficient and degree distribution of public transport networks in 5 Chinese cities.The structures of these networks approximate to random graphs,which does not exhibit the scale-free property as other countries.Through the analysis about the practical interpretation of those statistical parameters,the authors proposed some possible reasons to generate the structural differences between Chinese and other countries. |
