A risk-based methodology for modeling, assessing, and managing risks to the Hampton roads bridge tunnels

Abstract

This project seeks to address the need of the Virginia Department of Transportation (VDOT) to identify and manage the increasing number of interdependencies within the highway system. It incorporates risk assessment and risk management methodologies in the analysis of a terrorist attack or natural disaster for three major bridge-tunnels in Southeast Virginia. The results of this study provide insight into how to manage the cascading effects of interdependency risks to the individual case studies, and to the state of Virginia as a whole. Management policies were developed to unlock the transportation system interdependencies and to reduce the impacts to them following a transportation disruption.
