description: The 2002 Household Travel Survey for the municipality of Anchorage, Alaska entailed the collection of activity and travel information for household members during a specific 24-hour period. In addition to providing basic information about each household and its members, the survey documented specific characteristics of activities and trips made, including number and purpose of trips, time of day, and mode of transportation. Travel days for the survey were spread across the pilot study (February 12-15, 2002) and the full study (April 1, 2002 -- May 17, 2002). In total, 2,035 households were recruited to participate in the study. Of these, 1,293 completed travel diaries, and the information was retrieved from all household members age 5 and older. The 1,293 completed surveys included an over sample of 242 households in the Eagle River and Chugiak communities. These numbers do not include an intercept sample of 174 users of the People Mover.
description: For information on weights, please see the study documentation provided with this release. Users should be aware that the "Data Weighting" section of the Technical Report describes several weight variables; of those described, only "expwgt" and "finwgt" are present in the data file.
description: Response Rates: During the recruitment phase, 2,035 RDD households agreed to participate in the study for a recruitment response rate of 43 percent. About 16 percent refused to participate in the study. The response rate was calculated under standards of the Council of American Survey Research Organizations (CASRO). It was derived by dividing the number of households that agreed to participate by the sum of the total number of "eligible" households and a portion of the households for whom "eligibility" was unknown.
description: Probability sample using a random digit dial (RDD) sample, in which the primary sampling units were telephone numbers. Both listed and unlisted telephone numbers were generated using random digit dial (RDD) procedures. Listed numbers were generated from working exchanges and blocks for the telephone numbers in the study area (FIPS code 02020). NuStats then generated all the possible combinations of telephone numbers within these working exchanges and blocks. Unlisted telephone numbers were randomly generated based on the telephone exchanges and blocks identified for the listed sample. All generated unlisted telephone numbers that were listed in the database were eliminated from the sampling frame. In all, 12,000 total telephone numbers were generated into 116 replicates. Two enrichment oversamples were added: (1) Households in Eagle River/Chugiak, and (2) People Mover users. For additional information on sampling, please see the study documentation provided with this release.

description: computer-assisted telephone interview (CATI); face-to-face interview; mail questionnaire; on-site questionnaire; telephone interviewThis collection has not been processed by ICPSR. The deposited files are being released as they were received from the Principal Investigator.The dataset was compiled from three basic databases: household, person, and trip. The merging procedure was conducted using the common variables household ID, which was present in all three datasets, and person ID, which was present in the person and trip datasets. The resulting dataset has one record for each trip, which included all of the person and household information for the tripmaker.NuStats conducted the Household Travel Survey, in association with NuStats' DataSource, Cambridge Systematics, and CH2MHill. NuStats designed the survey, managed data collection, and analyzed the survey data. NuStats' DataSource conducted the telephone interviews and mailed the diary packets. CH2MHill's Anchorage office provided local support for the survey effort, while Cambridge Systematics produced a technical memorandum detailing the specifications for updating the travel-forecasting model.For additional information regarding the Anchorage Household Travel Survey, please visit the Metropolitan Travel Survey Archive Web site.
