The 1995 San Diego Travel Behavior Study was designed to examine the relationship between characteristics of households and travel behavior. This travel survey relied on the willingness of area residents to complete diary records of their daily travel. Recruitment of households was conducted through a "recruitment interview" in which respondents were informed of the survey, its purpose and the respondent's obligation to complete diaries. Data on households and household members were also collected during the recruitment interview, including whether the respondent was a homemaker, how often the respondent worked from home, and the number of vehicles in the household. Participating households were assigned a "travel day" during which household members were asked to record travel information in their diaries for a specified 24 hour period. Respondents were asked to document detailed information regarding their trips including number of trips and information about parking. Demographic variables include gender, age, race, whether the respondent held a valid driver's license, employment status, whether the respondent had a disability, occupation, and whether the respondent was a student.
