Nationwide Personal Transportation Survey, 1990: [United States] (ICPSR 9816)
Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 1990-03-01--1991-02-01
This survey provides information on the nature and characteristics of personal travel in the United States. Data are provided on personal trips for all purposes and using all modes of transportation. Both household-level and personal-level data were collected. For each contacted household, information was collected on household vehicles, number of drivers in household, number of accidents during the past five years, availability of public transportation, household location, size and composition of household, and household income. In addition, each household was assigned a specific 24-hour "travel day" and a 14-day "travel period" for which detailed data on all travel were collected. Person-level interviews were attempted with each member of the household over 5 years of age. Persons over 13 years of age were asked to report all trips they had taken on the designated travel day, as well as trips of 75 miles or longer taken during the 14-day travel period ending on the travel day. A knowledgeable household resident, aged 14 or older, was asked to report all trips taken by household members between the ages of 5 and 13 years. The person-level interview also collected information on occupation and work-related travel, driver information, and accidents. The data are provided in six files. Part 1, the Household File, contains demographic information on the household as well as data on drivers and vehicles in the household. Part 2, the Person File, includes demographic data on individuals in the household, information on modes of transportation to work and costs for parking, and details on traffic accidents in the past five years. Part 3, the Vehicle File, provides information on vehicles owned or used by household members, including make, model, year, and mileage. Information on the 24-hour travel day and the 14-day travel period is contained in the remaining three files.
