Nationwide personal transportation study, 1977 [United States]

Description

The Nationwide Personal Transportation Study (NPTS) was designed to collect information on all trips taken during a designated 24-hour period and some additional detail on trips of 75 miles or more during the preceding 14-day period. Data was also gathered on the availability and use of public transportation, types of motorized vehicles available to the household, characteristics of the trips taken including mode, purpose, miles traveled, time required, and persons on the trip. There are thirty-two files, eight files per quarter. The files are: Household Characteristics, Household Members, Household Vehicle Information, Occupation and Travel-to-Work Data, Travel Day Trip Data, 14-Day Travel Period Trips, Stop Data for 14-day Travel Period Trips, and Annual Long Trip Data from the National Travel Survey for the 13,365 households common to both studies.
