Evaluating Bridge Network Resilience Using Socio-Technical Attributes
Implementing Partner: Build Change
Project name: Evaluating Bridge Network Resilience Using Socio-Technical Attributes in Japan
This project analyzed Japan’s bridge network resilience by assessing individual structural integrity and interdependencies within the transportation system.
Bridges, often the weakest links, can cause disruptions ranging from minor delays to critical connectivity failures. By examining these socio-technical interactions, the study identifies high-risk bridges, guiding targeted improvements.
This approach enhances infrastructure safety, optimizes disaster preparedness, and strengthens overall network resilience against environmental and operational challenges, ensuring long-term functionality and reliability.

Impact
1
The study assessed bridge resilience by combining structural integrity and traffic flow analysis, revealing how individual bridges impact overall network functionality during disruptions. This approach informs targeted improvements to enhance connectivity and disaster preparedness in transportation systems.
2
Three recovery strategies—user priority, road type priority, and damage type priority—were evaluated to determine their effectiveness in restoring bridge network functionality. The findings help decision-makers optimize post-disaster recovery, ensuring efficient and resilient transportation infrastructure restoration.
3
Prioritizing regular maintenance and proactive pre-disaster planning minimizes damage and accelerates recovery, strengthening the resilience and reliability of the bridge network. This approach ensures sustained functionality and adaptability against future hazards and operational disruptions.
