This research presents two results. One a framework that visualizes transportation system risk profiles, with a particular focus on earthquakes, and another a model that uses this information to optimize recovery strategies. The first uses data from the United States Geological Survey (USGS) to create a risk probability map that is used to create individual risk profiles that are combined to form a cumulative risk profile. The second is the combination of a constructor, ordering algorithm, and traffic simulator that optimizes recovery strategies. The presented framework and model can be utilized together for simulation purposes, or separately where the first can be used to easily visualize failure probabilities to assist with planning and where the second can be used to determine effective recovery strategies in the aftermath of any disaster, not exclusively a seismic event. This framework and model provide valuable information that can be used to improve the Memphis area infrastructure system by improving infrastructure resilience and emergency recovery strategies and have the ability to be calibrated to any area of concern with minimal effort.125
