U.S. Freight on the Move: Highlights from the 2007 Commodity Flow Survey Preliminary Data. Special Report

摘要

More than 13 billion tons of freight, valued at $11.8 trillion, were transported nearly 3.5 trillion ton-miles in the United States during 2007, according to preliminary estimates from the 2007 Commodity Flow Survey (CFS). The CFS, a survey of shippers sponsored by the Bureau of Transportation Statistics (BTS) in partnership with the Census Bureau, provides a detailed, multimodal picture of national freight flows. The survey is the only publicly available source of national commodity fl ow data for the highway mode. CFS data are collected every 5 years as a component of the national Economic Census and provide a benchmark on the value, tonnage, ton-miles, distance shipped, and mode used to transport commodities. Analysis and research utilizing CFS data are used to make decisions in the public and private sectors involving policy, infrastructure, and the economy.
