ABSTRACT
The successful implementation of Advanced Traveler Information Systems (ATIS), a component of Intelligent Transportation Systems (ITS), depends on user acceptance of ATIS products and services. The focus of much ITS and ATIS research to date, however, has been on technical issues rather than on user acceptance. User acceptance is particularly important to the successful implementation of ATIS because the accuracy of traffic information it conveys is dependent on the number of ATIS-equipped vehicles. The navigational task required each participant to follow a route depicted by one of the four navigational aids while the videotape of the route was shown on the front monitor. The videotape was paused at selected intersections during which the participant indicated the proper direction that the car should take by pressing the appropriate arrow key. A factor analysis was conducted to determine if the questionnaire tapped underlying dimensions of navigational preferences.
