Table 1a. Shipment Characteristics by Mode of Transportation for the United States: 2007
[Estimates are based on final data from the 2007 Commodity Flow Survey. Because of rounding, estimates may not be additive]
|Mode of transportation||2007 Value
|2007 Average miles per shipment||Value CV2||Tons CV||Ton-miles CV||Average miles per shipment CV|
|Air (included truck and air)||252,276||3,611||4,510||1,304||8.2||10.4||9.6||2.2|
|Parcel, U.S.P.S. or courier||1,561,874||33,900||27,961||975||2.1||2.6||3||2.4|
|Truck and rail||187,248||225,589||196,772||1,007||5.6||6.2||5||6.3|
|Truck and water||58,389||145,521||98,396||1,429||12.5||15.3||15.6||9|
|Rail and water||13,892||54,878||47,111||1,928||19.2||26.9||27.6||13.1|
|Other multiple modes||45,320||113,841||46,402||1,182||13.3||8.7||11.4||14|
|Other and unknown modes||279,113||271,567||33,764||116||7.8||14||9.2||13|
KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality.
1 Ton-miles estimates are based on estimated distances
traveled along a modeled transportation network.
2 Coefficient of Variation.
3 "Truck" as a single mode includes any shipment that was made by private truck only, by for-hire truck only, or by a combination of private and for-hire truck.
4 Estimates for pipeline exclude shipments of crude petroleum.
NOTES: Value-of-shipment estimates are reported in current prices. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
