Value Per Ton of U.S. Freight Shipments by
Transportation Mode: 1993 and 2002*
NOTE: The data are plotted on a log scale. Data that span a wide range are
often plotted on a log scale to display variations at the low end as clearly
as variations at the high end. For example, this figure would not show any
detail below $1,000 per ton if it had used the familiar linear scale.
Multimodal includes the traditional intermodal combination of truck and rail plus truck and water; rail and water; parcel, postal, and courier service; and other intermodal combinations.
The data in this figure include the Bureau of Transportation Statistics estimates of out-of-scope missing pieces. See notes on table 1 for additional information on the BTS estimates.
