This study quantitatively evaluates the damage to road facility network caused by flooding and analyzes the resulting network performance degradation and recovery process. Terrain data resembling urban areas were generated, and flood simulations were conducted under various rainfall scenarios to analyze inundation depth and area within the road facility network. The analysis quantified the performance degradation of individual road facilities as well as the network-level performance loss. At the network level, a topological analysis was conducted to evaluate connectivity and importance, while an economic analysis and a resilience analysis quantified the extent of network performance degradation and recovery, respectively. The results revealed that damage to key links in the central region of the network had a significant impact on overall network performance. Furthermore, structural damage to bridges and road inundation were identified to contribute substantially to economic losses. This approach was adopted to comprehensively assess the degradation and recovery of road facility networks affected by flooding. |
