Seattle Household Travel Survey Wave 2, 1990 (ICPSR 34784)

Principal Investigator(s):


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.

Data Collection Notes:

Users may notice that study documentation refers to the "Puget Sound Transportation Panel". ICPSR has retained the "Seattle Household Travel Survey" title that was provided by the data depositor. No additional information was provided regarding the title discrepancy.

The Original P.I. Documentation contains conflicting study time period and collection dates for this wave.

For additional information on all waves of the Seattle Household Travel Survey, please visit the Metropolitan Travel Survey Archive Web site and the Puget Sound Regional Council Web site.


Study Purpose:   The panel was undertaken to serve three basic objectives: (1) to be a metropolitan "current population survey" to track changes in employment, work characteristics, household composition, and vehicle availability; (2) to monitor changes in travel behavior and responses to changes in the transportation environment; and (3) to examine changes in attitudes and values as they affect mode choice and travel behavior. Information gained from the panel has aided long range transportation forecasting and analysis used in decisions regarding highway and road construction, transit development, and carpooling and parking policies.

Sample:   For information on sampling, please see the Original P.I. Documentation section of the ICPSR Codebook.

Time Method:   Longitudinal: Panel

Weight:   The data contain weight variables "HWGT" (Household weight) and "PWGT" (Person weight) that may be used in data analysis. For additional weighting information, please see the Original P.I. Documentation section of the ICPSR Codebook.

Mode of Data Collection:   mail questionnaire, telephone interview

Extent of Processing:  ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.
