| 2007 | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | |
|---|---|---|---|---|---|---|---|
| Highway1 (Btu per vehicle-mile) | 21,238 | 21,008 | 21,024 | 21,499 | 21,677 | 21,525 | 21,540 |
| Railroad (Class I) (Btu per freight-car-mile) | 14,846 | 14,573 | 13,907 | 13,733 | 14,043 | 13,800 | 14,607 |
| Railroad (Class I) (Btu per ton-mile) | 320 | 305 | 291 | 289 | 298 | 294 | 296 |
| Domestic Waterborne Commerce (Btu per ton-mile) | 225 | 252 | 225 | 217 | 211 | 210 | NA |
KEY: Btu = British thermal unit; NA = not available.
1Includes heavy single-unit and combination trucks. Heavy single-unit trucks are trucks that have two axles and at least six tires or a gross vehicle weight rating exceeding 10,000 pounds. Based on a new methodology, FHWA revised its annual vehicle-miles traveled, number of vehicles, and fuel economy data beginning with 2007. Energy intensity data are based on the new FHWA methodology. 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 pre-2011 editions of Freight Facts and Figures.
