Version V1

The 2002 Treasure Valley Transportation Survey was conducted in the counties of Ada and Canyon in southwest Idaho, under contract to the Community Planning Association of Southwest Idaho (COMPASS). The full Study was conducted during the months of September and October 2002 and entailed the collection of activity and travel information for all household members, regardless of age, during an assigned 24-hour period (Tuesday, Wednesday, or Thursday). The project included a two-stage procedure. The first stage involved a recruitment telephone interview to collect demographic information from the household, such as income, household size, and age and employment status of all persons in the household. The travel day was also assigned during the recruitment interview. The second stage consisted of a retrieval telephone interview to collect all travel information for the assigned travel day.

Both listed and unlisted telephone numbers were generated using a modified random digit dial (RDD) procedure. Listed numbers were randomly selected in the study area. After identifying all of the area code/exchange and block combinations within the list (i.e., the first eight numbers within a ten-digit phone number), NuStats then generated all the possible combinations of telephone numbers within these exchanges and blocks. All randomly generated unlisted telephone numbers that were listed in the database were purged from the sampling frame. In all, 30,000 total telephone numbers were generated into 100 replicates (note that only 83 replicates were dialed). For additional information, please refer to the Original P.I. Documentation section of the ICPSR codebook.
