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

NOTES: Heat equivalent factor used for joules conversion is 38,657,950 joules/liter.

In January 2000, the American Public Transit Association changed its name to the American Public Transportation Association. The Transit Fact Book is now refered 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.
