(1) The FHWA estimates national trends by using State reported Highway Performance and Monitoring System (HPMS) data, fuel consumption data (MF–21 and MF–27), vehicle registration data (MV–1, MV–9, and MV–10), other data such as the R. L. Polk vehicle data, and a host of modeling techniques. For 2011, changes in a couple of States’ truck VMT substantially impacted national truck VMT trends. Upon further review with the States involved, FHWA still considers these changes as material fact. However, FHWA will conduct further analysis when the 2012 data are reported by the States in 2013.

(2) Light Duty Vehicles Short WB – passenger cars, light trucks, vans and sport utility vehicles with a wheelbase (WB) equal to or less than 121 inches. Light Duty Vehicles Long WB – large passenger cars, vans, pickup trucks, and sport/utility vehicles with wheelbases (WB) larger than 121 inches. All Light Duty Vehicles – passenger cars, light trucks, vans and sport utility vehicles regardless of wheelbase.

(3) Single–Unit – single frame trucks that have 2–axles and at least 6 tires or a gross vehicle weight rating exceeding 10,000 lbs.

(4) Vehicle occupancy is estimated by the FHWA from the 2009 National Household Travel Survey (NHTS); For single unit truck and heavy trucks, 1 motor vehicle mile travelled = 1 person–mile traveled.

(5) VMT data are based on the latest HPMS data available; it may not match previous published results.

(6) The change in the number of buses is primarily due to the decline of reported public operated school buses.
