Abstract:Global transportation infrastructure today is confronted with significant vulnerabilities — an aging infrastructure; a growing concentration of populations at high-density coastal urban areas; increasing interdependencies among the nation's physical and cyber infrastructures; co-location of many transportation systems with large-scale and potentially hazardous production facilities; and the escalating threats of climate change. Together, they have coalesced to create significant challenges for the nation's critical infrastructure systems. A framework for enhancing critical transportation infrastructure resiliency could serve as a roadmap for addressing some of these pressing global challenges. Recently, the concept of resiliency, however, has become a buzzword used to characterize a system that recovers rapidly from a disruption in order to resume normal functions. But, RESILIENCY IS MORE THAN BOUNCING BACK. The U.S. Department of Transportation's Volpe Center hosted a roundtable of experts to explore resiliency in the context of challenges facing the nation's transportation system. The experts concurred that resiliency requires a change in focus from near-perfect efficiency to planned redundancy, flexibility, fault-tolerance, and resourcefulness. A resilient transportation infrastructure will be able to anticipate threats—both natural and man-made—and will be able to absorb shocks and adapt to changing conditions. With a resilient approach, we can rebuild better and smarter, recognizing that no infrastructure exists in isolation. Resiliency will make our future infrastructure reliable, sustainable, and survivable.
