Excel | CSV | Figure Version

KEY: * 2002 data are preliminary.

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. These estimates cover logging, farm-based truck shipments, truck imports from Canada and Mexico, rail imports from Canada and Mexico, air cargo imports and exports, water imports and exports, and pipeline crude and petroleum products shipments. These estimates exclude other out-of-scope categories of goods movements for which no reasonable basis for an estimate currently exists including, government shipments, service sector, retail sector, construction sector, transportation service providers, household goods movement, and municipal solid waste.
