Seattle Household Travel Survey Wave 2, 1990

Résumé 0

The Seattle Household Travel Survey Wave 2, 1990, is the second wave in a ten-part longitudinal panel survey of the travel patterns of households in the Puget Sound region of Washington State. The survey series was initiated in 1989 by the Puget Sound Council of Governments (now known as the Puget Sound Regional Council); wave 2 was conducted in 1990. This collection contains the second set of panel data for approximately 2,000 households in King, Kitsap, Pierce, and Snohomish counties. Due to various sources of attrition, approximately 20 percent of households needed to be replaced for each survey wave. The survey relied on the willingness of study area residents to (1) provide demographic information about the household, its members, and its vehicles, (2) document all travel for each household member, aged 15 years or older, for an assigned 2-day period, and (3) agree to participate in additional survey waves. After an initial telephone screening, survey participants received mailed travel diaries to aid in documenting travel information for the 2-day assessment period. Respondents were instructed to record their mode of transportation, trip purpose, number of passengers, departure and arrival times, ride fare, and parking cost. Demographic information for this study includes age, gender, education, employment status, and household income.
