The Nationwide Personal Transportation Survey serves as the nation's inventory of daily personal travel. It collects data on daily trips including purpose of the trip, means of transportation used, travel time, vehicle occupancy, driver characteristics, and vehicle attributes. These data are collected for all personal trips, all modes and purposes, all trip lengths, all areas of the country, all days of the week, and all months of the year. Part 1, the Household File, contains data on the relationship between household members and demographic information for household members. The file also contains information on housing characteristics, as well as characteristics of the block group and census tract. Availability and distance to public transportation are also included. Part 2, the Person File, contains information on seat belt use, modes of transportation used for travel to work, and costs for parking. Part 3, the Vehicle File, contains data relating to each of the household's vehicles, including whether a particular household member usually drives the vehicle, when it was purchased, the vehicle type, and model year. Part 4, the Travel Day Trip File, contains data about each trip the person made on the household's randomly assigned travel day. Information was collected on the purpose of the trip, the number of trips within the trip chain, where the trip chain started, and the amount of time spent at each destination. Part 5, the Segmented Travel Day Trip File, contains data for up to four segments of each segmented travel day trip the person made on the travel day. The file contains information on the start time, mode of transportation used, purpose, and duration of each travel segment. Part 6, the Travel Period File, contains data for every trip of at least 75 miles one way that the person took during a 14-day period ending on the travel day. The file contains information on the start date, purpose, and transportation mode used for trip. New for the 1995 survey was a written diary, used to help respondents to better remember their travel on their designated travel day, and a household roster of trips, which was used to assist respondents in recalling trips made with other household members. New questions included satisfaction with the nation's transportation system, reactions to mobility and congestion, perceived difficulties in travel, and use of seat belts.
