Table 1b. Shipment Characteristics by Mode of Transportation for State of Origin: Percent of Total for 2007 and 2002

Estimates are based on data from the 2007 and 2002 Commodity Flow Surveys. Because of rounding, estimates may not be additive.

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 "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.
3 Estimates for pipeline exclude shipments of crude petroleum.

NOTES: Rows are not shown if all cells for that particular row have no values. For example, specific state by mode rows are not shown in this table because there are no data for those rows. Value-of-shipment estimates are reported in current prices.
