1.459972 tonne-kilometers = 1 ton mile.

Description:

a Beginning with 2006 data, Pipeline data were taken from PHMSA F 7000-1-1. Previously, data were extracted from FERC Form No. 6, which included data for federally-regulated pipelines. For 2005, data for federally regulated Pipelines were estimated to include about 90 percent of the total national ton-miles, so the Pipeline statistics for that year were adjusted to include an additional 10 percent of ton-miles. From 1990 through 2004, the federally regulated estimate was 84 percent with a 16 percent addition for other Pipeline ton-miles.

b The large increase in Water carrier Ton-miles between 1975 and 1980 reflects the entrance of the Alaska pipeline, moving crude petroleum for water transportation to U.S. refineries.

c The amount carried by Motor carriers is estimated.
