As the basic and important service facilities of the national economy, the smooth and safe operation of expressway is of great practical significance to promote the stable development of transportation industry and support the implementation of national strategy. Therefore, in order to improve the ability of expressway to deal with sudden traffic accidents and its operation and maintenance resilience, this study introduces the theory of safety resilience into the safety management of expressway sections, uses word frequency analysis to identify the main factors of high-speed operation and maintenance safety resilience, and constructs an evaluation system of operation and maintenance resilience. An expressway operation and maintenance resilience evaluation model based on improved dung beetle algorithm optimization (WFA-Critical-IAHP-DBO-ELM) was established and applied to a section of Chang-Zhang Expressway. Compared with random forest model and XGBoost model, it is proved that DBO-ELM model has strong generalization ability and evaluation accuracy. This paper provides a scientific evaluation solution for improving the resilience of expressway and provides reference for engineering practice.
