“…Extreme weather events, particularly intense rainfall, can quickly lead to urban flooding, damaging transportation infrastructure such as roads and bridges. These events may disrupt the normal operation of transportation systems and, in severe cases, impede emergency rescue operations and other critical city functions, profoundly affecting economic activities and residents' well-being [6][7][8]. As a vital transportation hub and industrial center in Northeast Asia, Changchun's development and the well-being of its residents are heavily reliant on the resilience of its transportation infrastructure [9,10].…”

As climate change intensifies, urban transportation infrastructure faces unprecedented challenges from extreme weather events, such as floods. This study investigates the resilience and vulnerability of such infrastructure under extreme rainfall conditions in Changchun City. Utilizing Multi-Criteria Decision-Making Analysis (MCDM) and Geographic Information System (GIS) techniques, we comprehensively assess the physical, functional, and service vulnerabilities of the transportation network. Our analysis reveals that only 3.57% of the area is classified as highly resilient, demonstrating effective flood management capabilities. In contrast, a significant 61.73% of the area exhibits very low resilience, highlighting substantial vulnerabilities that could impact urban operations. Based on our findings, we propose specific strategies to enhance resilience, including optimizing drainage systems, upgrading infrastructure standards, implementing green infrastructure initiatives, and integrating disaster risk factors into urban planning. These strategies and insights provide valuable references for global cities facing similar climatic challenges.
