Energy Consumption by Mode of Transportation (metric)

KEY: Btu = British thermal unit; N = data do not exist; R = revised; U = data are not available.

^a Domestic operations only.

^b Includes fuel used in air taxi operations, but not commuter operations. Data for 1996 are estimated using new information on no respondents and are therefore not comparable to earlier years. See the accuracy statement in the appendix for more detailed information. 

^c Data from 2007 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories...

KEY: N = data do not exist; R = revised; U = data are not available.

^a Data from 2007 were calculated using a new methodology developed by FHWA. Data for these years are based on new categories and are not comparable to previous years. The new category Light duty vehicle, short wheel base replaces the old category Passenger car and includes passenger cars, light trucks, vans and sport utility vehicles with a wheelbase (WB) equal to or less than 121 inches. The new category Light duty vehicle, long wheel base replaces Other 2-axle, 4-...

Average Length of Haul, Domestic Freight and Passenger Modes (metric)

System Kilometers Within the United States

KEY:  N = data do not exist; R = revised; U = data are not available.

^a All public road and street mileage in the 50 states and the District of Columbia. For years prior to 1980, some miles of nonpublic roadways are included. No consistent data on private road mileage are available. Beginning in 1998, approximately 43,000 miles of Bureau of Land Management Roads are excluded. 2010 Missouri and Wyoming's data are 2009.

^b Data represent miles of road owned (aggregate length of road, excluding yard tracks, sidings, and parallel lines...

Bus Profile

KEY:  N = data do not exist; R = revised; U = data are unavailable.

^a In 2003, the Federal Motor Carrier Safety Administration implemented a program to improve reporting by Class I intercity bus carriers. This accounts for the large increase in Number of operating companies between 2002 and 2003, and as a result the large increase in Operating revenues and Operating expenses. For all years, New Jersey Transit has been excluded from the totals because of its status as a publicly run carrier.

Energy Intensity of Transit Motor Buses (Metric)

KEY: KWH = Kilowatt hour; N = data do not exist.

^a Before 2002, Other major fuels includes liquefied petroleum gas, methanol, ethanol, and bunker fuel. From 2002 - 13, Other major fuels includes liquefied petroleum gas, methanol, ethanol, bunker fuel, kerosene, and grain additive. After 2013, other major fuels includes liquefied petroleum gas, ethanol and hydrogen.

^bPower includes electric propulsion and electric battery.

Transit Industry Electric Power and Primary Energy Consumption and Travel

KEY:  kWh = kilowatt hour; N = data do not exist.

^a Prior to 1984, the data in this table include the energy consumption of bus, heavy rail, light rail and trolley bus. Commuter rail, automated guideway, urban ferryboat, demand responsive vehicles, and most rural and smaller systems are excluded from the data during this period.

^b 1960 to 1991 data include propane. Series not continuous between 1991 and 1992. 1992 to 1995 data include propane, liquefied natural gas, bio/soy fuel, biodiesel, hydrogen, methanol and ethanol,...
