Fuel Estimates

Since the 1990’s, SRC has conducted surveys related to fuel consumption for various state agencies. Analyses of fuel consumption data for vehicles used off-road such as motorboats, ATV’s, aircraft, and snowmobiles are provided on a recurring basis to the managing agency. Using the survey data collected, SRC computes statewide estimates of annual fuel usage for these motorized vehicles.
