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 truck and for-hire truck.
4 Estimates for pipeline exclude shipments of crude petroleum.

NOTES: Rows are not shown if all cells for that particular state by mode have no data. For example, since North Carolina by "Pipeline" has no data for any weight grouping, the entire mode of "Pipeline" for that state was removed from this table. However, if a state by mode has at least one row of data for one of the weight groupings, then the entire state by mode is shown even though there may be rows absent of data within that mode. For example, North Carolina by "Air" has a few rows absent of data but since the other rows within that mode do have data, that state by mode will be shown in its entirety for all the weight groupings. Value-of-shipments estimates have not been adjusted for price changes. 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/.
