摘要:

分析了法国勒芒市的城市道路网络。研究了网络的度分布、聚类系数、直径和特征路径长度等拓扑性质。这些结果表明,我们的网络是一个“小世界”网络,具有短的平均最短路径和大的聚类系数。在度分布中发现了与单次幂律分布不同的双次幂律分布,并给出了一种新的度分布函数。通过对该函数的分析,扩展了对自然界中广泛分布的双幂律分布的起源的理解。

英文摘要:

An urban road network of Le Mans in France is analyzed. Some topological properties of network are investigated, such as degree distribution, clustering coefficient, diameter, and characteristic path length. These results suggest that our network is a "small- world" network with short average shortest path and large clustering coefficient. Furthermore, double power-law distribution is found in degree distribution which is distinct from the single power-law and a novel degree distribution function is also given. Some analysis on this function extend the comprehension of the origination of the double power-law distribution widely dispersed in nature.
