Figure 8

(A) Comparison between the empirical delay distribution (left) and the empirical cluster size distribution (right), with the results coming from the simulations for the Italian (Red) and German (Blue) Railway Networks. Different curves correspond to different parameters of β. The optimal β value is 0.15 for Italy and 0.1 for Germany. The distribution shown in these panels are inverse cumulative distributions. (B) Cluster Diameter as a function of the cluster size obtained with the empirical data and with the simulations. Dotted lines represent the case in which clusters are path-shaped. Left part represents results from data and simulation for the Italian system. Right part is for Germany. Upper panels show the diameter computed without considering the geographical distance between the nodes (with the black lines showing the behaviour in which clusters have a compact shape), lower panels take this distance into account. Results in (A) and (B) have been obtained by simulating the full-day schedules of March and April 2015, both for the Italian and German case. In this figure all the quantities that have not a specified unit of measurement are adimensional
