Assessing Network Criticality for Climate Adaptation Planning

Since climate adaptation resources are limited, criticality assessment is essential for the prioritization of infrastructure adaptation efforts. Assessment methods are not well developed. This project will address this adaption barrier in three ways. First, the research team will evaluate the current criticality assessment practices of Departments of Transportation and Metropolitan Planning Organizations. Documenting current practices will support the dissemination of refined criticality assessment tools, enhancing the impact of this project. Second, the research team will develop methods to find the appropriate network resolution for conducting criticality assessment modeling. Since criticality is a function of both travel demand and network connectivity, it is essential to determine the modeling resolution (in terms of the completeness of the road network and the spatial disaggregation of origin and destination matrices) needed to produce accurate criticality ratings. Third, the research team will evaluate the impact of the geographic scale of criticality modeling on criticality ratings. The evaluation of appropriate resolutions and geographic boundaries for criticality modeling will build on prior work by the project team developing and refining the Network Robustness Index, a link-specific metric measuring the impact of individual road links on system performance. This project will provide transportation agencies with an improved tool for objectively evaluating asset criticality.
