Risk and Resilience Analysis Tool for Infrastructure Asset Management

This project develops a comprehensive analytical framework for risk-based infrastructure asset management for both normal and extreme management conditions. We integrate analytical procedures for quantitative risk assessment, asset management, and economic impact analysis into a holistic methodological framework for comprehensive assessment of the benefit and cost of proposed infrastructure management strategies or scenarios. Moving beyond this, the framework incorporates the bidirectional impacts between asset maintenance (for normal aging and deterioration) and risk management against extreme conditions. The framework producing quantitative cost and risk measures is useful for addressing the high-level questions that agencies face in long-term planning and management decision making such as project prioritization, resilience planning, and capital planning. To illustrate the application, the framework is applied to a case study on the surface transportation system of the United States Virgin Islands considering flood risk. Finally, a scalable and customizable GIS-based web tool implementing the risk assessment methodology is developed incorporating real data for USVI and multiple future flood scenarios with sea level rise.
