KEY: R = revised; S = data are not published because of high sampling variability or other reasons; U = data are unavailable.

a Truck as a single mode includes shipments that went by private truck only, for-hire truck only, or a combination of both.
b 1993 and 1997 data exclude most shipments of crude oil. 2002 and 2007 data exclude shipments of crude petroleum.
c Ton-miles estimates are based on estimated distances traveled along a modeled transportation network.
d Percent change has been revised in conjuction with 2007 data.

NOTES
Numbers may not add to totals due to rounding. Value-of-shipment estimates are reported in current prices. Coverage for the 2002 and 2007 Commodity Flow Survey (CFS) differs from the previous surveys due to a change from the 1997 Standard Industrial Classification (SIC) system to the North American Industry Classification System (NAICS) and other survey improvements. The 2007 estimates are derived using an improved methodology of estimation.
