NOTES: 2002 data
are preliminary. Although final 2002 Commodity Flow Survey data were
available when this report was prepared, final 2002 supplemental data were
still forthcoming. Thus, all 2002 data could not be updated for this report. 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. Preliminary
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.
