Abstract:

The magnitude of societal and economic impacts associated with natural and man-made disasters experienced in this decade has generated heightened awareness of the importance of infrastructure resiliency. Transportation systems are key to response and recovery at local and regional levels. As such, they must hold up under stress maintaining baseline service levels and must be robust enough in physical design and operational concept to provide a degree of self-restoration to prevent a destructive event from becoming the catalyst for a degenerative epoch. Implications of non-resilient transportation systems on quality of life and economic efficacy of a locality or region are tremendous. Engineering disciplines have made great advances in design and assessment, increasing resiliency for the built environment. However, those involved in infrastructure investment decisions face a significant challenge when seeking guidance for measuring resiliency for complex and adaptive systems such as transportation. Decision makers need metrics, integrating frameworks, and decision support tools to test investment strategies against a range of potential event sequences. This paper presents a framework supporting sketch level resiliency assessment leading to consistent, regionally adaptive approaches to quantify resiliency, test for robustness, and test for sensitivity supporting prioritization of individual investments and formation of investment bundles. The approach recognizes that transportation resiliency metrics and data structures are in early development stages and builds upon previous research in transportation resiliency. The paper presents an application of the methodology using the Interstate 95 corridor as the setting for the evaluation of the network’s resiliency.
