Bay Area Travel Survey, 1990 (ICPSR 34796)

Principal Investigator(s): Charns, Harold, E.H. White and Company, Inc.; Nelson, Bonnie, Nelson/Nygaard Consulting Associates

Summary:

The 1990 Bay Area Travel Survey sampled households in California's nine-county Bay Area (including the cities of San Francisco, Oakland, and San Jose) in order to collect detailed travel data regarding residents' driving habits and public transit use. Potential respondents were identified via computer generated random telephone sampling; willing participants were tasked with completing a mailed travel diary for each household member over the age of 5 for an assigned "typical weekday" of travel activity. Respondents recorded details of their movement throughout the day, including trip locations, mode of transportation, bridges traversed, public transit routes, trip start and end times, trip purpose, trip activities, number of passengers, and cost of transit fare and/or parking. Following the assigned travel day, a second call was placed to each respondent in order collect the travel diary data. Demographic information for individuals and households includes gender, age, driver's license status, ethnicity, employment status, occupation, household size, and income.
