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, service sector, retail sector, construction sector, transportation service providers, household goods movers, and municipal solid waste providers.

Current dollar amounts were converted to chained 2000 dollars by BTS to eliminate the effects of inflation over time.
