Statistical analysis of 22 public transport networks in Poland

Abstract

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 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 500 and assortative large networks N 500 is observed.

Scale-Free Network Theory in Studying the Structure of the Road Network in Poland

“…The public transport systems in Polish cities were analysed by Sienkiewicz and Hołyst [22], who concluded that the distribution degree can follow a power law or be described by an exponential function, depending on the assumed definition of network topology. All of the above studies concern free-scale network.…”

Networks of companies and branches in Poland

“…During the last few years various models of networks [1,2] have become a powerful tool for analysis of complex systems in such distant fields as Internet [3], biology [4], social groups [5], ecology [6] and public transport [7]. Modeling behavior of economical agents is a challenging issue that has also been studied from a network point of view.…”
