Truck freight
Annual truck miles traveled are annual vehicle miles traveled by freight trucks on state highways. Trucks are categorized into three types: single-unit, double-unit, and triple-unit trucks based on the Federal Highway Administration's 13-bin vehicle classification.
Freight truck border crossings are defined as the number of freight trucks entering Washington state from Canada.
The Truck travel time reliability index (interstate) is the ratio of a longer truck travel time (95th percentile) to a "normal" truck travel time (50th percentile) on the interstate highway system. The lower the value of the index, the more reliable truck travel is.
