KEY: S = data are not published because estimate did not meet publication standards; Z = rounds to zero.
1 Ton-miles estimates are based on estimated distances traveled along a modeled transportation network.
2 Truck as a single mode includes shipments that went by private truck only or by for-hire truck only.
3 Excludes crude petroleum shipments.
NOTES: 1 metric tonne = 1.1023 short tons. 1 tonne-kilometer = .6849 ton-miles. 1 kilometer = .6214 miles. Value-of-shipment estimates have not been adjusted for price changes. Numbers and percents may not add to totals due to rounding.
