A periodic national survey that provides comprehensive information on travel by the U.S. population, along with related socioeconomic characteristics of the tripmaker. The Nationwide Personal Transportation Survey (NPTS) is designed to allow an analysis of travel by characteristics of the trip (e.g., length, purpose, mode), the tripmaker (e.g., age, sex, household income) and the vehicle used (e.g., model year, vehicle type, make and model). NPTS surveys were conducted in 1969, 1977 and 1983 by the Bureau of Census (BOC) for the Department of Transportation (DOT). The 1990 NPTS was sponsored by a group of DOT agencies, specifically the Federal Highway Administration (FHWA), Federal Railroad Administration (FRA), National Highway Traffic Safety Administration (NHTSA), Office of the Secretary (OST), and the Federal Transit Administration (FTA). The survey was conducted for DOT by Research Triangle Institute. Information was collected on all trips taken by each household member age 5 and older during a designated 24-hour period, known as a "travel day," and on trips of 75 miles or more taken during the preceding 14-day period, known as the "travel period." The trip information was expanded to annual estimates of trips and travel. The survey encompassed trips on all modes of transportation for all trip purposes and all lengths.
