Freight Facts and Figures 2011
Table 3-6. Annual Vehicle Distance Traveled by Highway Category and Vehicle Type: 2009
Freight moving in combination trucks depends heavily on the Interstate System. Although only one-fourth of the distance traveled by all traffic is on the Interstate System, nearly one-half of combination-truck vehicle miles of travel is on the Interstate System.

Notes:
Based on a new methodology, FHWA revised its annual vehicle miles travelled, number of vehicles, and fuel economy data beginning with 2007. Information on the new methodology is available at www.fhwa.dot.gov/policyinformation/statistics.cfm. Data in this table should not be compared to those in previous editions of Freight Facts and Figures. Numbers may not add to totals due to rounding.
