Estimated Gross State Product
ODOT's Statewide Transportation Model will be utilized to estimate the amount of gross state product (GSP) being created by the project over a 20 year horizon. The estimated dollar amount of GSP is a measure of the estimated economic output with respect to the movement of flows of goods and services. The estimated GSP created will e derived by the total project cost to establish a ratio of GSP created per million dollars of project cost. the estimated GSP is derived from the modeled transportation efficiencies attributed to the project.
