KEY: R = revised; U = data are not available.
a Includes freight, express, and
mail revenue tonne-kilometers as reported on U.S. DOT Form 41.
b Intercity truck and oil
pipeline estimates are reported in billions.
The U.S. Department of Transportation, Bureau of Transportation
Statistics converted these estimates to millions.
c Revenue tonne-kilometers.
d Excludes intraterritorial
traffic, for which tonne-kilometers were not compiled.
e Reflects startup between 1975
and 1980 of Alaska pipeline and consequent water transportation of crude
petroleum from Alaskan ports to mainland United States for refining.
NOTES
Numbers may not add to totals due to roundings.
1.459972 tonne-kilometers = 1 ton mile.
