KEY: R = revised; U = data are not available.
a Includes freight, express, and mail revenue ton-miles as reported on U.S. DOT Form 41.
b Methodology was changed in 1990 for intercity trucks. Therefore figures prior to 1990 are not comparable to those after 1990.
c Excludes intraterritorial traffic, for which ton-miles were not compiled.
d The large increase between1975 and 1980 was a result of a new 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.
