Statistical analysis of Polish public transport networks. — •Julian Sienkiewicz and Janusz A. Hołyst — Faculty of Physics, Warsaw University of Technology, Koszykowa 75, 00-662 Warszawa, Poland

We have analyzed Polsih public transport networks of sizes ranging form N=152 to N=2881. Depending on the assumed definition of network topology the degree distribution can either follow a power law or can be described using an exponential function. Distributions of path lengths in all considered networks are given by asymmetric, unimodal functions. Clustering, assortativity coefficient and betweenness centrality are studied. All considered networks exhibit small world behavior and are hierarchically organized. We have observed a transition between dissortative small networks N < 500 and assortative large networks N > 500.
