Abstract:

In recent years, the increasing frequency of extreme weather events has caused significant disruptions to urban transportation networks, leading to reduced road capacity, impaired mobility, severe economic losses, and even casualties. Efficient road network restoration strategies are critical for rapidly restoring functionality and enhancing network resilience. However, traditional approaches primarily focus on ground transportation, neglecting the emerging potential of ground-air coordinated systems.The application of the ground-air coordinated mode in future urban settings is explored and a multimodal transportation network framework integrating urban surface traffic and low-altitude air mobility is developed. Considering network resilience, repair crew dispatching costs, and multimodal traffic flow distribution, a bi-level optimization model for post-disaster road network restoration is proposed. The upper-level model determines the repair sequence for damaged road segments and the allocation of low-altitude air traffic resources, while the lower-level model incorporates an extended user equilibrium traffic assignment framework that accounts for ground-air collaboration. Based on the characteristics of the model, an adaptive large neighborhood search heuristic algorithm based on node importance is developed. The proposed model and algorithm are validated using the Sioux-Falls network. Results demonstrate that the ground-air collaborative mode effectively alleviates ground traffic congestion, accelerates road network recovery, and enhances overall resilience. It provides a theoretical basis for optimizing urban road network restoration strategies in response to major emergencies.
