Summary
This report details the findings of the Rental User Study and Local User Study, components of the TravTek Operational Test Evaluation conducted in Orlando, Florida, from 1992 to 1994. TravTek was a large-scale field test of an Advanced Traveler Information System (ATIS) and Advanced Traffic Management System (ATMS), developed through a public-private partnership involving the Federal Highway Administration, General Motors, and the American Automobile Association. The research aimed to evaluate user perceptions, performance, and acceptance of in-vehicle navigation and traffic management technologies under naturalistic driving conditions. The study involved two distinct participant groups: 2,896 rental users, primarily Orlando visitors who used TravTek-equipped vehicles for 4 to 6 days, and 51 local users, Orlando residents who used the vehicles for approximately two months. The vehicles were equipped with route planning, route guidance, local service databases, and real-time traffic information. To assess specific feature impacts, vehicles were configured in three modes: Services (S, control), Navigation (N, no real-time traffic), and Navigation Plus (N+, full features). Data collection methods included automated in-vehicle data logs, questionnaires, and debriefings. The evaluation focused on driver workload, safety perceptions, feature usage frequency, display preferences, and willingness-to-pay. Results indicated that both rental and local users found the route planning and guidance features useful and easy to use. TravTek was utilized on more than half of all trips, with rental users frequently employing the simplified turn-by-turn guidance display supplemented by synthesized voice instructions. Although local users slightly preferred the moving map display without voice supplementation, they also predominantly used the guidance display with voice. Crucially, users reported feeling more attentive and less distracted while using TravTek compared to driving without it, and they perceived the system as aiding in safer driving. Regarding economic value, users estimated a willingness-to-pay of approximately $1,000 for the complete system, valuing navigation and route planning features highest, followed by real-time traffic information and local databases. The study concludes that TravTek was favorably received by both transient and resident drivers, demonstrating positive impacts on driver attention and perceived safety. The high frequency of use and significant willingness-to-pay suggest strong consumer acceptance of ATIS technologies. These findings provide empirical evidence supporting the utility of in-vehicle navigation and traffic management systems, highlighting that such tools can enhance driver confidence and trip efficiency without increasing distraction. The results offer critical insights for the development and deployment of Intelligent Transportation Systems, emphasizing the importance of intuitive interfaces and voice supplementation in user adoption.
Key finding
