波兰22个公共交通网络的统计分析

Statistical analysis of 22 public transport networks in Poland

Julian Sienkiewicz, Janusz A. Holyst

摘要:

对波兰22个城市的公共交通系统进行了分析。这些网络的大小范围从N=152到N=2881。根据网络拓扑的假设定义,度分布可以遵循幂律,也可以用指数函数来描述。在所有考虑的网络中的路径的分布是由非对称,单峰函数。研究了聚类性、可拓性和介数。所有被考虑的网络都表现出小世界行为,并且是分层组织的。观察到溶解性小网络N<=500和溶解性大网络N>=500之间的过渡。

英文摘要:

Public transport systems in 22 Polish cities have been analyzed. Sizes of these networks range from N=152 to N=2881. Depending on the assumed definition of network topology the degree distribution can follow a power law or can be described by an exponential function. Distributions of paths in all considered networks are given by asymmetric, unimodal functions. Clustering, assortativity and betweenness are studied. All considered networks exhibit small world behavior and are hierarchically organized. A transition between dissortative small networks N<=500 and assortative large networks N>=500 is observed.
