Washington State Freight System Resiliency

The economic viability and well-being of Washington State is significantly influenced by the freight transportation system serving the region. An increased understanding of the vulnerability of this freight system to natural disasters, weather, terrorist acts, work stoppages and other potential freight transportation disruptions will provide the State with the information necessary to assess the resiliency of the transportation system, and provide policy makers with the information required to improve it. This research project will: a) Identify a set of threats or categories of threats to be analyzed; b) Assess the likelihood of each event occurring within certain time horizons; and c) With the threats and their probabilities, analyze the resiliency of the Washington transportation system. This will include 1) identifying the most valuable and least valuable components, both infrastructure and operational characteristics, of the transportation system with respect to moving freight, 2) identify the most likely events and the impact of those events, and 3) develop strategies for making Washington State Department of Transportation (WSDOT) investments that would support improvements in the resiliency of the transportation system. Deliverables may include the following: i. Identification of the most likely events and failures; ii. Identification of the weak points in the transportation system; iii. Identification of improvements that will have the largest benefits in terms of the state’s ability to move freight when faced with a transportation system failure; iv. Identification of the most important elements of the transportation system in terms of the state’s ability to move goods; and v. Provide suggestions as to how WSDOT investments can best improve the resiliency of the transportation system. The outcome of this research effort will help shape and guide transportation policy and infrastructure investment decisions in the future.
