Disaster-blocking events significantly impact the normal operation of highways. As climate change intensifies, mountainous highways are increasingly susceptible to such disaster events, and the consequences are becoming more severe. Therefore, it is imperative to conduct research on the resilience assessment of the function of mountainous highway networks. Based on the highway network resilience assessment framework and the entropy weight method, an evaluation index system for segment importance has been developed. This system includes metrics such as node degree, intermediary degree, closeness centrality, and clustering coefficient to identify key segments of the highway network. Socioeconomic development indicators are selected in conjunction with the Criteria Importance Through Intercriteria Correlation (CRITIC) method to calculate the traffic influence index of urban nodes. A gravity model is constructed to assess the traffic connection strength between towns, and a generalized connectivity cost calculation method is proposed. Additionally, urban connectivity efficiency indices and urban connectivity demand satisfaction indicators are established. A resilience assessment index system for the function of mountainous highway networks is created to evaluate the connectivity function of highway networks. The highway network in the disaster-prone Western Sichuan Plateau is selected for the case analysis. The established assessment method for the functional resilience of the highway network can effectively identify the key sections of the network and analyze the impact of disaster events on its normal operation. This study can provide a reference for highway management agencies to take targeted resilience-enhancing measures and enhance the resilience of the highway network against disasters.
