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

^a All operations other than those operating under 14 CFR 121 and 14 CFR 135. Data for 1996 are estimated using new information on nonrespondents and are not comparable to earlier years. Mileage in source is multiplied by 1.151 to convert to nautical-miles for 1985-1997.

^b In July 1997, the FHWA published revised vehicle-miles data for the highway modes for many years. The major change reflected the reassignment of some vehicles from the passenger car category to the Other 2-axle 4-tire vehicle category. This category was calculated prior to rounding.

^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 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.

^e Motor bus and Demand responsive figures are also included in the Bus figure for Highway.

^f National Passenger Railroad Corporation (Amtrak) began operations in 1971.

^g Although both Train-kilometers and Car-kilometers are shown for rail, only Train-kilometers are included in the total. A Train-kilometer is the movement of a train, which can consist of multiple vehicles (cars), the distance of 1 kilometers. This differs from a vehicle-kilometer, which is the movement of 1 vehicle the distance of 1 kilometer. A 10-vehicle train traveling 1 kilometer would be measured as 1 train-kilometer and 10 vehicle-kilometers. Caution should be used when comparing train-kilometers with vehicle kilometers.

^h 1960-65, Motorcycle data are included in Passenger car, and Other 2-axle 4-tire vehicle data included in Single-unit 2-axle 6-tire or more Truck.

ⁱ Ferry boat included with Other.

NOTES

Numbers may not add to totals due to rounding.

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.
