a All operations other than those operating under 14 CFR 121 and 14 CFR 135.
b 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 ofTransportation, Bureau of Transporation Statistics by subtracting the most current motorcycle figures from the aggregate passenger car and motorcycle figures.
c 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.
d Motor bus and demand responsive figures are also included in the bus figure for highway.
e Amtrak began operations in 1971. Does not include contract commuter passengers.
f Included in passenger car.
g Included in other single-unit 2-axle 6-tire or more truck.
h Ferry boat included in other.
i Includes commuter rail figures only.
KEY: N = data do not exist; P = preliminary; R = revised.
NOTES: Air carrier passenger-kilometers are computed by summing of the products of the aircraft-kilometers flown on each interairport segment multiplied by the number of passengers carried on that segment. Highway passenger-kilometers 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 Nationwide Personal Transportation Survey, conducted by the Federal HighwayAdministration, and the Truck 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.
