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 the mainland United States for refining.

NOTE

Numbers may not add to totals due to rounding.
