years are not yet available.
b In July 1997, the USDOT, Federal Highway Administration, reassigned some vehicle-miles from "passenger car"
to "other 2-axle, 4-tire."
c Includes municipally-owned transit,
commercial, federal, and school buses.
d Car-miles.
e Includes light and heavy rail only.
f Fiscal year data. Amtrak began operations in 1971.
g Includes demand-responsive, ferry boat, and other transit not specified; 1980 data include "other transit"
only.
Key: N = data do not exist;
P = preliminary;
R = revised.
