The Washington State Freight and Goods Transportation System is a classification system for roadways, railways, and waterways based on freight volume. The FGTS is used to establish funding eligibility for Freight Mobility Strategic Investment Board grants, fulfill federal reporting requirements, support transportation planning process, and plan for pavement needs and upgrades. WSDOT has used this data to designate freight economic corridors in the Freight Mobility Plan.
WSDOT, with the assistance of the Association of Washington Cities and the County Road Administration Board, updates the FGTS classifications on a periodic basis as required by the Washington State Legislature. Revisions to the FGTS are developed by the agency having jurisdiction over the roadway segment. WSDOT maintains the statewide database and manages the update process.
WSDOT started the process of updating the Freight and Goods Transportation System in June 2015 and has completed the update in March 2016. 2015 FGTS report, detailed maps, and classification tables are published online.
The FGTS classifies roadways using the following categories:
T1: more than 10 million tons per year
T2: 4 million to 10 million tons per year
T3: 300,000 to 4 million tons per year
T4: 100,000 to 300,000 tons per year
T5: at least 20,000 tons in 60 days and less than 100,000 tons per year
Truck freight tonnage values are derived from actual or estimated truck traffic counts and converted into average weights by truck type.
The FGTS classifies railways using the following categories:
R1: more than 5 million tons per year
R2: 1 million to 5 million tons per year
R3: 500,000 to 1 million tons per year
R4 100,000 to 500,000 tons per year
R5 less than 100, 000 tons per year
The FGTS classifies waterways using the following categories:
W1: more than 25 million tons per year
W2: 10 million to 25 million tons per year
W3: 5 million to 10 million tons per year
W4: 2.5 million to 5 million tons per year
W5: 0.9 million to 2.5 million tons per year
