Freight Facts and Figures 2009Table 2-2. Value of Shipments by Transportation Mode: 2002, 2008, and 2035The value of freight moved on the U.S. transportation system is increasing faster than tons transported, even when calculated in 2002 prices. Growth in value between 2002 and 2008 is 26.8 percent, compared to 11.2 percent in tons. Imports and exports also account for a larger share of value than tons, accounting for 15.2 percent of the value in 2008. Billions of 2002 dollars
1Intermodal includes U.S. Postal Service and courier shipments and all intermodal combinations, except air and truck. Intermodal also includes oceangoing exports and imports that move between ports and interior domestic locations by modes other than water. 2Pipeline and unknown shipments are combined because data on region-to-region flows by pipeline are statistically uncertain. 3Data do not include imports and exports that pass through the United States from a foreign origin to a foreign destination by any mode. Notes: The 2008 data are provisional estimates, which are based on selected modal and economic trend data. Methods used to develop these estimates have improved over time, and as a consequence, previously released annual provisional estimates are superseded by the 2008 estimates in this table. Numbers may not add to totals due to rounding.
