Abstract: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. 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 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 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.
