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.

NOTES: Rows are not shown if all cells for that particular row have no values. For example, specific UN Numbers are not shown in this table because there are no data for those rows. Value-of-shipment estimates are reported in current prices. Estimated measures of sampling variability for each estimate known as coefficients of 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/publications/commodity_flow_survey/.
