The 1977 NPTS was conducted by the Bureau of the Census under joint sponsorship of FHWA, NHTSA, UMTA and OST, as part of the expanded scope of the National Travel Program conducted every 5 years by the Bureau of the Census. The 1977 NPTS was designed to update the earlier study done in 1969 to provide comprehensive data on travel and transportation patterns in the United States. The 1977 study was designed to collect information on all trips taken during a designated 24-hour period (travel day) and some additional detail on trips of 75-miles-or-more during the preceeding 14-day period (travel period), along with related social-economic characteristics of the tripmaker. Ten reports have been published. These include: (1) Characteristics of Licensed Drivers and Their Travel; (2) Household Vehicle Ownership; (3) Purposes of Vehicle Trips and Travel; (4) Home-to-work Trips and Travel; (5) Household Vehicle Utilization; (6) Vehicle Occupancy; (7) Life Cycle of Travel by the American Family; (8) Urban/Rural Split Travel; (9) Household Travel; and (10) Estimates of Variances.
