2. Rsearch Design and Data Collection
After identifying the three case studies which represent different types of transit service, a questionnaire was developed to understand the passengers perspective regarding transit. The data were collected from passengers riding the paratransit buses in the three case studies areas: Northland area , Fairlane Mall, and Groesbeck corridor. In each area, respectively, 75, 50 and 86 people completed the questionnaires. The questionnaire included four parts: The first part comprised questions about the passengerís current trip, such as the origin and destination, type of transit used, if the trip required a transfer, and information concerning the booking of the trip. These questions were designed to provide objective data for each case study about waiting time, transfer time, walking distance, and convenience of booking and information. The second part asked respondents to consider a hypothetical trip; respondents were asked where they would like to go, how they would get there, and how many transfers would be involved. The purpose of this section was to determine whether passengers use transit for other trips, and the extent to which this depends on the accessibility of transit. The third part focused on traveler preferences regarding transit service. The Forth part of the questionnaire included demographic and other descriptive information that past research has shown is correlated with traveler behavior such as having a valid driving license, the availability of a car, and SES.
