KEY: N = data do not
exist; P = preliminary; 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-kilometers 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-kilometers
for passenger car, motorcycle, and other 2-axle 4-tire vehicles were derived
by multiplying vehicle-kilometers for these vehicles by average vehicle
occupancy rates, provided by the Nationwide Personal Transportation Survey
(1977, 1983, and 1995) and 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.
d Motor 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-kilometers.
Car-kilometers measure individual vehicle-kilometers in a train. A
10-car train traveling 1 kilometer would equal 1 train-kilometer and 10
car-kilometers.
f Amtrak began operations in
1971. Does not include contract commuter passengers.
g Included in passenger car.
h Included in other
single-unit 2-axle 6-tire or more truck.
i Includes commuter rail
figures only.
j Ferryboat included in other.
NOTES
Air
carrier passenger-kilometers are computed by summing the products of the
aircraft-kilometers flown on each interairport segment multiplied by the
number of passengers carried on that segment.
Highway passenger-kilometers from 1960 to 1994 are calculated by
multiplying vehicle-kilometers 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-kilometers are the cumulative sum of the distances ridden by each
passenger. Rail passenger-kilometers
represent the movement of 1 passenger for 1 kilometer.
1.609344 kilometers = 1 mile.
