Project No.: CY1-TAMU-OU-03
Title: Risk-Based Assessment of System-Wide Vulnerability and Interdependency of Transportation Infrastructure Networks under Extreme Events
Performing Institution: Texas A&M University and University of Oklahoma
Principal Investigator: Maria Koliou, Texas A&M University; Arif Sadri, University of Oklahoma
Start and Anticipated Completion Dates: 09/01/2023-08/31/2024
Abstract: Synergistic Project Scope (TAMU/OU): Transportation networks comprise components such as bridges and roadways, which are made up of different subcomponents such as decks, girders, abutments, piles, embankments, and pavements. Many of these components are designed to withstand natural hazards expected with a given probability of recurrence. Given that transportation networks are often impacted by changing conditions and disruptions in the face of extreme events and societal expectations, it is important to prioritize our infrastructure improvements to provide the greatest enhancement to system resilience. Assessing the impacts of system-wide vulnerabilities and interdependencies is critical to prioritizing infrastructure enhancement for optimum system performance. This project will develop a framework based on network science theories and risk-based reliability analysis to account for the following: (1) the relative importance of system components; and (2) the interconnectedness of components and sub-components. While the major focus of the TAMU team will be on hurricanes in coastal regions, the OU team will consider inland flooding, creating a synergy between the lead institutions in looking at diverse weather extremes in the USDOT Region 6.
