摘要：	Compiled and published by the U.S. Department of Transportations Bureau of Transportation Statistics (BTS), National Transportation Statistics presents information on the U.S. transportation system, including its physical components, safety record, economic performance, energy use, and environmental impacts. National Transportation Statistics is a companion document to the Transportation Statistics Annual Report, which analyzes some of the data presented here, and State Transportation Statistics, which presents state-level data on many of the same topics presented here. The report has four chapters: Chapter 1 provides data on the extent, condition, use, and performance of the physical transportation network. Chapter 2 details transportations safety record, giving data on accidents, crashes, fatalities, and injuries for each transportation mode and hazardous materials. Chapter 3 focuses on the relationship between transportation and the economy, presenting data on transportations contribution to the gross domestic product, employment by industry and occupation, and transportation-related consumer and government expenditures. Chapter 4 presents data on transportation energy use and transportation-related environmental impacts. Appendix A contains metric conversions of select tables. BTS obtained the data in this report from many sources, including federal government agencies, private industry, and associations. Documents cited as sources for the tables provide detailed information about definitions, methodologies, and statistical reliability. Some of the data are based on samples and are subject to sampling variability. / Supplementary Notes: See also report for 2006, PB2006-109267. / Availability Note: Product reproduced from digital image.
