1 Estimates represent activity for a given mode across single and multiple mode shipments. For example, "Truck" ton-miles includes total ton-miles for shipments moving only by truck plus ton-miles for truck segments of multiple mode shipments.
2 Estimates for pipeline exclude shipments of crude petroleum.
3 Ton-miles estimates are based on estimated distance traveled along a modeled transportation network.
KEY: S = withheld due to high sampling variability or poor response quality.
NOTES: The data presented in these tables exclude shipments from the following establishments classified in the North American Industry Classification System (NAICS) as: farms, forestry, logging, fisheries, construction, publishing, and crude petroleum production; households; governments; and most retail and service businesses. Also excluded are most imports and commodities shipped from a foreign location to another foreign destination that pass through the United States. Estimates are preliminary and may be revised.
