| Scope and Method of Study: This study performed a literature review and case studies on various methods of conducting on-board surveys. Three test scenarios were developed to assess the effect of: (1) length of questionnaire, (2) different incentives, and (3) surveyors on the response rate, unit cost, and duration of a survey. These scenarios were tested on three selected routes of Tulsa Transit.;Findings and Conclusions: Using short questionnaires with six essential O/D questions obtained a higher response rate and a lower unit cost compared to questionnaires with 14 and 29 questions. As an incentive to complete a questionnaire, offering a drawing to win 31 days free pass obtained a higher response rate, but increased the unit cost compared to offering a two free-ride. Using surveyors, either male or female, increased the response rate compared to the method of using boxes, while it increased the unit cost of the survey. |
