NOTES: 2002
Commodity Flow Survey and supplemental data are preliminary. Multimodal includes the traditional
intermodal combination of truck and rail plus truck and water; rail and
water; parcel, postal, and courier service; and other multiple modes for the
same shipment. Supplemental 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 supplemental categories of goods movement for which no reasonable basis
for an estimate currently exists, including government shipments; the
service, retail, and construction sectors; transportation service providers;
household goods movers; and municipal solid waste providers.
