(1) These composite estimates include Commodity Flow Survey
(CFS) data and out-of-scope shipments for sectors that are not included in
the CFS, such as imports, logging, construction, retail, services,
publishing, municipal solid waste, and household and business moves. They
also include estimates of in-scope shipments for sectors that are covered in
CFS, including some sectors that may have been underestimated due to small
sample size, such as exports, intermodal, and petroleum products.
(2) "Truck" as a single mode includes shipments that were made by only private truck only, for-hire truck, or a combination of private and for-hire truck.
(3)Estimates for pipeline include shipments of crude petroleum.
(4) Other multiple modes include combination of truck and water, rail and water, and other combinations.
