Major freight railways, including Class 1 railroads, major rail yards, and intermodal facilities.Bridges on the National Highway System and major evacuation routes.Major roadways, including the National Highway System and evacuation routes.For purposes of this study, the critical multimodal network for the three state metropolitan region was defined as follows: Other regions have used a combination of expert input and qualitative measures to assign criticality.Įarly conversations with the project partners involved defining the scope of the transportation system to be assessed in this study, given available resources. Some regions have chosen to use an objective, data-driven approach to assigning a criticality score to each element of the transportation system, but these analyses have tended to be for a single mode (e.g., a regional highway network). Scope of Regional Exposure AnalysisĪn important step in conducting a regional vulnerability assessment is to conduct a system-level assessment of criticality to prioritize the assets and networks that are the highest priority for adaptation investments. This appendix contains additional detail about the regional-level exposure analysis. Regional Exposure AnalysisĪs described in Section 4.0, the Post-Sandy study team conducted a regional assessment of exposure to climate stressors as a first step in identifying subareas and facilities that should be priorities for more detailed analysis.
