We integrate methods in statistical physics to investigate the correlation between PTN topological features and their operational stability. Initially, to present a PTN in the form of a complex network (i.e. a graph con- sisting of vertices-nodes and edges-links), we perform a coarse-graining procedure. We merge stations considered to be within a reasonable pedestrian walking distance (e.g. stops across the street) by implementing a DBSCAN clustering algorithm to the transport dataset. Subsequently, we analyse the topological features of the resulting complex net- works in various network representations reflecting PTN operational features. In the second part of our analysis we assess the vulnerability of PTNs by removing network constituents according to different protocols (attack scenarios). We observe correlations between network topological features and its stability with respect to random failures and targeted attacks. Додано в НРАТ 2025-11-05 Закрити
