KEY: kWh = kilowatt hour; N = data do not exist; P = preliminary; R = revised.

^a Prior to 1985, excludes commuter rail, automated guideway, urban ferryboat, demand responsive vehicles, and most rural and smaller systems.

^b For 1992-96, includes propane, liquid petroleum gas, liquefied natural gas, kerosene, and all other nondiesel fuels except compressed natural gas. 1960 to 1991 data include propane. Series not contiguous between 1991 and 1992.

NOTES: The heat equivalent factors used in Btu conversions are: diesel = 38,657,950 joules/liter; electric = 3,600,000 joules/kWh, negating electrical system loses (to include electrical system loses, multiply this conversion factor by approximately three) gasoline = 34,839,537 joules/liter.

In January 2000, the American Public Transit Association changed its name to the American Public Transportation Association (APTA). The Transit Fact Book is now referred to as the Public Transportation Fact Book.

Numbers may differ slightly from previous year's metric tables because a higher precision conversion factor was used.
