KEY:
(1) Ton-miles estimates are based on estimated distances traveled along a modeled transportation network.
(2) Coefficient of Variation.

NOTES: These data are preliminary and are subject to change; they will be superseded by data released in later reports. Value-of-shipment 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.
