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

a All operations other than those operating under 14 CFR 121 and 14 CFR 135.
b In July 1997, FHWA published revised passenger-miles data for the highway modes for a number of years. The major change reflected the reassignment of some vehicles from the passenger car category to the other 2-axle 4-tire vehicle category. Passenger-miles for passenger car, motorcycle, and other 2-axle 4-tire vehicles were derived by multiplying vehicle-miles for these vehicles by average vehicle occupancy rates, provided by the Nationwide Personal Transportation Survey (1977, 1983, and 1995) and the National Household Travel Survey (2001).
c U.S. Department of Transportation, Federal Highway Administration (FHWA), provides data separately for passenger car and motorcycle in its annual Highway Statistics series. However, the 1995 summary report provides updated data for passenger car and motorcycle combined. Passenger car figures in this table were computed by U.S. Department of Transportation, Bureau of Transportation Statistics by subtracting the most current motorcycle figures from the aggregate passenger car and motorcycle figures.
dMotor bus and demand responsive figures are also included in the bus figure for highway.
e Prior to 1985, excludes demand responsive and most rural and smaller systems funded via Sections 18 and 16(b)2, Federal Transit Act. The series is not continuous between 1980 and 1985. Transit rail modes are measured in car-miles. Car-miles measure individual vehicle-miles in a train. A 10-car train traveling 1 mile would equal 1 train-mile and 10 car-miles.
f Amtrak began operations in 1971. Does not include contract commuter passengers.
gMotorcycles are included in Passenger car in 1960 and 1965.
hOther 2-axle 4-tire vehicles are included in single-unit 2-axle 6-tire or more truck in 1960 and 1965.
i Ferry boats are included in Other in 1980 and 1985.

NOTES
Air carrier passenger-miles are computed by summing the products of the aircraft-miles flown on each interairport segment multiplied by the number of passengers carried on that segment. Highway passenger-miles from 1960 to 1994 are calculated by multiplying vehicle-miles of travel as cited by FHWA by the average number of occupants for each vehicle type. Average vehicle occupancy rates are based on various sources, such as the National Household Travel Survey, conducted by the Federal Highway Administration, and the Vehicle Inventory and Use Survey, conducted by the Bureau of the Census. Transit passenger-miles are the cumulative sum of the distances ridden by each passenger. Rail passenger-miles represent the movement of 1 passenger for 1 mile.
Numbers may not add to totals due to rounding.
2007 data for Bus, Paratransit (Demand responsive), and Other are not comparable to earlier years due to change in the method of data collection and estimation by the American Public Transportation Association (APTA).
Transit data from 1996 and after are not comparable to the data for earlier years or to the data published in previous editions of the report due to different data sources used.1 mile = 1.609344 kilometers
