• Abstract:
  The Orlando Test Network Study was one of a series of investigations conducted as part of the TravTek operational test of an ; advanced traveler information and traffic management system (ATIS/ATMS). The TravTek system consisted of the Orlando ; Traffic Management Center (TMC), the TravTek vehicles, and the TravTek Information and Services Center. The TMC ; broadcast updated travel times for TravTek traffic links to the TravTek vehicles once each minute. The TravTek vehicles ; broadcast their link travel times back to the TMC for transmission to the other TravTek vehicles. The vehicles were equipped ; to provide route planning, route guidance, and a data base of local services and attractions. The primary purpose of this study ; was to evaluate the effects of alternative driver interfaces on driver performance, navigation performance, driver perception, ; driver preference, and willingness-to-pay. ; A controlled experiment was conducted in which up to six TravTek vehicles traveled the same origin to destination (O/D) ; pairings to evaluate six alternative information presentation configurations: five TravTek alternatives and a control configuration. ; Three visual display conditions were tested: a moving map display, a symbolic guidance display, and a condition with no ; visual display. Two aural conditions were tested in combination with the three visual conditions: synthesized voice guidance ; and no voice guidance. The six information presentation configurations were evaluated both in the day and at night. Five of ; six combinations utilized the TravTek and one configuration (no visual display and no voice guidance) was considered the ; Control condition. The drivers in the Control condition had to plan and navigate to their destination as “they normally would” ; without the use of automated route planning and route guidance. Data from 3 18 drivers are presented. ; TravTek benefits to individual drivers included travel time savings and a reduction in perceived workload. Both the moving ; map and simplified turn-by-turn visual displays were very effective compared to the Control condition, particularly when the ; visual displays were supplemented with synthesized voice guidance. User perception and performance data suggest that the ; system was easy to learn and easy to use. Participants in this study indicated that they would be willing to pay about $1000 for ; a system such as the one they drove.
