Box B - What Isn’t Covered by the CFS and BTS Estimates
While the BTS estimates of total freight
shipments provide the most complete commercial freight picture for all
modes of transportation, they exclude most shipments by the retail sector
and government shipments, such as goods for defense operations, and collection
of municipal solid waste. The estimate also excludes possible shipments by nongoods producing
sectors such as services, construction, household goods movements, and
transportation service providers.
