摘要: To further our understanding of travel behavior, the U.S. Department of Transportation (US DOT) conducts the Nationwide Personal Transportation Survey (NPTS) to obtain information on personal travel of U.S. households with respect to why, how, when, where from, where to, how frequency, how long, and with whom. The NPTS also provides information by subgroups of the population, e.g., by age, gender, race, zero-vehicle households, which allows important policy analyses of how transportation serves these groups. The NPTS has been conducted in 1969, 1977, 1983, 1990, and 1995.
