摘要：	The 2001 National Household Travel Survey (NHTS) is the first comprehensive household survey of both daily and long-distance travel, allowing for analysis of the full continuum of personal travel by Americans. This report highlights the breadth of topics covered by the survey, the different kinds of analyses possible using the data gathered, and the unique features of these data. In addition to providing the first comprehensive look at travel by Americans, the 2001 NHTS also incorporates additional enhancements to the previous survey designs. For example, long-distance travel was expanded to include trips as short as 50 miles and, for the first time, includes trips made for the purpose of commuting to work--often overlooked segments of personal long-distance travel. The survey also introduces the first look at the daily travel characteristics of children under the age of five years. presented in this report.
