KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality. - = Zero or Less than half the unit shown; thus, it has been rounded to zero.
1 Ton-miles estimates are based on estimated distances
traveled along a modeled transportation network.
2 "Truck" as a single mode includes any shipment that was made
by private truck only, by for-hire truck only, or by a combination of private
and for-hire truck.
3 Estimates for pipeline exclude shipments of crude petroleum (SCTG 16).
NOTES: Value-of-shipment estimates are reported in current prices. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
