20.500.12556/RUL-182819 Network accessibility as the emergence of cliques We propose a topological formulation of accessibility based on the notion of Access Graph, in which two nodes are connected if they are reachable within a given travel time. We trace the emergence and evolution of its subgraphs with imposed levels of connectedness, specifically maximal clique and k-cores. We propose two complementary sets of accessibility indicators, cumulative and threshold, based on integral measures of subgraph growth and times at emergence of k-cores, respectively. For a meaningful comparison of networks across different dimensions, we contrast the realised accessibility with that of an idealised network on the same set of nodes. The proposed measures offer a view of accessibility that extends beyond the commonly used node-averaged indicators. Empirical analysis of 42 metro networks worldwide demonstrates universal patterns of accessibility behaviour. We illustrate the practical application of this approach on a case study where we examine the accessibility impacts yielded by alternative infrastructure and service developments. Our results amount to the reconceptualisation of accessibility within the complex network framework. public transport accessibility network science transport network javni potniški promet teorija omrežij prometno omrežje true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-25 08:36:09 2026-05-25 08:36:11 2026-05-26 04:35:51 0000-00-00 00:00:00 2026 0 0 Str. 1-27 art. 5089 Vol. 16 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 004.7:656.025.2 2045-2322 10.1038/s41598-026-35542-1 266608131 Sfiligoj_Network_accessibility.pdf Sfiligoj_Network_accessibility.pdf 1 F6C4DBE27EBCE6620651A73A17850B54 1fee6595787c422e9276e37adc00463f2a25a8b97d72b5f9ca5331929e66c1ee 277b2505-5809-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234365 https://www.nature.com/articles/s41598-026-35542-1 1 b13e9075-5803-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234361 Fakulteta za pomorstvo in promet Fakulteta za strojništvo 0 0 0
