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 Coefficient of Variation.
3 "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.
4 Estimates for pipeline exclude shipments of crude petroleum.

NOTES: Value-of-shipment estimates have not been adjusted for price changes. Estimated measures of sampling variability for each estimate known as coefficients or variation (CV) are also provided in these tables. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
