With the continuous expansion of urban public transport network, the traditional passive operation safety management mode has been unable to adapt to the development status of public transport system under the background of networked operation. How to improve the robustness and resilience of integrated transport network in the face of unexpected adverse events is one of the key issues that urgently need to be solved. Taking the urban subway-bus integrated transport network as the research object, the concept of resilience measurement and complex network is introduced. The subway-bus integrated transport network is established through the coupling relationship between the network layers, and the comprehensive resilience measurement model of the transport network considering the structural resilience and functional resilience is constructed. Based on the improved Coupled Map Lattice (CML) model, the network fault propagation mechanism and cascading failure behavior are studied, Based on the actual case study in Beijing, the results show that there are obvious differences in the resilience level of integrated networks under different networks, different attack sequences and attack methods, and the integrated transport network shows relatively poor resilience in the face of deliberate attacks, especially against rail transit stations; The disturbance coefficient R and coupling coefficient ε in the improved CML model have a significant impact on the cascading failure scale; After large-scale cascading failures, attacking the network with Jintai Road subway station as the initial attack node, it was found that the network resilience decreased by 0.92%. Our research provide methodological support for the construction, resilience enhancement, and safe and stable operation of urban public transportation networks.
