Develop Systematic and Quantitative Approach to Assess the Probability of Extreme Weather and Resilience Risks for TxDOT Highways and Bridges

Climate stressors pose a significant threat to transportation infrastructure. Recognizing this, Federal Highway Administration (FHWA) requires State Departments of Transportation (DOTs) to consider extreme weather and resilience in life cycle planning and risk management analyses within a State’s Transportation Asset Management Plan (TAMP). The 2022 Texas TAMP identified risk categories that could impact Texas Department of Transportation's (TxDOT's) infrastructure (specifically, highways and bridges). Extreme weather and resilience were discussed extensively, but the 2022 TAMP lacked a systematic and quantitative approach to assess climate-related risks to infrastructure and in life cycle planning analysis. The objective of this research is to develop a robust quantitative risk framework that can be implemented in subsequent Texas TAMPs. To successfully accomplish this objective, the researchers will: manage the project scope, budget, and timeline (1), conduct an extensive review of the literature (2), identify climate stressors to TxDOT's pavements and bridges (3), assess the probability of such climate stressors and extreme weather events (4), quantify the impact on bridges (5) and pavements (6), develop an asset risk and resilience assessment framework (7), develop and quantify adaptation strategies (8), conduct scenario analysis (9), and identify proxy indicators that can be tracked to monitor high-priority risks (10).
