作者提出了一种基于计算和功能图表示的大型城市街道网络的拓扑分析。该表示给出了一个功能视图，其中顶点表示命名街道，边表示街道交叉口。计算一系列图形度量，包括街道连通性、平均路径长度和聚类系数，以进行结构分析。为了表征街道网络中街道的不同聚类程度，他们将聚类系数概括为考虑 k 个邻居的 k 聚类系数。基于对三个城市的验证，作者表明大型城市街道网络形成小世界网络，但不表现出无标度属性。
The authors propose a topological analysis of large urban street networks based on a computational and functional graph representation. This representation gives a functional view in which vertices represent named streets and edges represent street intersections. A range of graph measures, including street connectivity, average path length, and clustering coefficient, are computed for structural analysis. In order to characterise different clustering degrees of streets in a street network they generalise the clustering coefficient to a k-clustering coefficient that takes into account k neighbours. Based on validations applied to three cities, the authors show that large urban street networks form small-world networks but exhibit no scale-free property.
