Summary:
Written Testimony of Anne Goodchild Professor in Civil and Environmental Engineering Director of the Supply Chain Transportation and Logistics Center University of Washington Joint Hearing on: “Where’s My Stuff? Examining the Economic, Environmental, and Societal Impacts of Freight Transportation” before the United States House Committee on Transportation and Infrastructure the Subcommittee on Highways and Transit and the Subcommittee on Railroads, Pipelines, and Hazardous Materials.

Summary:
The adoption of defensible performance measures and establishment of proven results has become a necessity of many state Transportation Departments. A major factor in demonstrating results is the impact a transportation infrastructure improvement project has on the region’s economic climate.

Summary:
This paper proposes a method for calculating both the direct freight benefits and the larger economic impacts of transportation projects. The identified direct freight benefits included in the methodology are travel time savings, operating cost savings, and environmental impacts. These are estimated using regional travel demand models (TDM) and additional factors. Economic impacts are estimated using a regional Computable General Equilibrium (CGE) model.

Summary:
In the face of many risks of disruptions to our transportation system, this research improves WSDOT’s ability to manage the freight transportation system so that it minimizes the economic consequences of transportation disruptions.
