Introduction

Compiled and
published by the U.S. Department of Transportation's 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 transportation's
    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
    transportation's 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. National Transportation Statistics is updated quarterly at www.bts.gov.
