以城市道路网中的连续道路中心线作为网络拓扑结构的基本分析单元,作者采用对偶法对我国12个不同规模和形态的城市道路网的拓扑结构进行了抽象,在此基础上分析了我国城市道路网拓扑结构具有的普遍复杂网络特性。研究指出,我国城市道路网的拓扑结构一方面具有较小的特征路径长度和较大的聚类系数,是典型的小世界网络;另一方面其度分布函数为幂律形式,又具有典型的无标度特性。
Abstract：Taking the smoothly continuous road center-line segments as the basic analysis unit of road network topology,the topologies of twelve urban road networks in China were abstracted with the dual approach,then the complex network characteristics of these urban road networks have been uncovered through statistic analysis.The conclusions showed that the topologies of these urban road networks in China had the universal properties of the small-world network and scale-free network.
