This paper examines the structural and reliability aspects of multilayer transportation networks. Using Space L, we construct these networks and develop a topology index system including node overlap degree, node activity degree, average path length, network diameter, clustering coefficient, betweenness, betweenness centrality, multilayer participation coefficient, edge overlap coefficient, and edge crossing coefficient. We evaluate reliability by analyzing node and edge failures. A case study demonstrates our method effectively captures node/edge heterogeneity and topological features in integrated transportation systems. Results show the metro-urban bus multilayer network exhibits small-world and scale-free properties. Nodes with high overlap/activity degree, betweenness, or participation coefficient significantly impact the network. Paths with larger edge overlap coefficients offer redundancy, faster recovery, and higher reliability post-failure. Networks with greater edge crossing coefficients exhibit enhanced redundancy and risk resistance.
