Results from the 2007 Commodity Flow Survey (CFS) show that about 70% of all freight movement in the U.S. is by truck, in terms of the shipment value and tonnage. Rail moves about 15% of freight tons, but moves those tons over great distances, accounting for 37% of ton-miles. Parcel delivery, US Postal Service (USPS) or courier service account for 13.5% of shipments by value, but less than half of one percent by tonnage.
