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。所有考虑的网络中的路径长度的分布是由非对称，单峰函数。研究了聚类、重复性和介数。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。观察到小于或类似于500的溶解性小网络N与大于或类似于500的溶解性大网络N之间的过渡。
Public transport systems in 22 Polish cities have been analyzed. The sizes of these networks range from N=152 to 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 path lengths 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 less than or similar to 500 and assortative large networks N greater than or similar to 500 is observed.
