PUGET SOUND COUNCIL OF GOVERNMENTS ORIGIN-DESTINATION TRAVEL SURVEY, 1985

Travel behavior of 783 households was collected using a mail-out travel diary and a follow-up telephone interview for data collection. Data was keyed directly onto a computer file during the telephone interview. This technique allowed quick access to the interview data and improved the accuracy of data collection. The response obtained was sufficiently large to calculate trips per household and length of trips by income quartiles with acceptable accuracy levels.
