KEY:
– Represents and estimate equal to zero or less than 1 unit of
measure.
S Estimate does not meet publication standards because of highly sampling
variability or poor response quality.
1 "Truck" as a single mode includes shipments that were made by only private truck, only for-hire truck, or a combination of private and for-hire truck.
2 Estimates for pipeline exclude shipments of crude petroleum.
