Summary
This report summarizes the global evaluation of TravTek, an operational field test of Advanced Traveler Information Systems (ATIS) and Advanced Traffic Management Systems (ATMS) conducted in Orlando, Florida, from 1992 to 1993. Sponsored by the Federal Highway Administration and involving partners such as General Motors, the American Automobile Association, and local transportation agencies, the study aimed to validate the concept of in-vehicle navigation and traveler information services. The evaluation sought to answer seven primary questions: whether the system functioned reliably, if it saved time and avoided congestion, if drivers would use and pay for it, how effective different guidance displays were, if the system was safe, and if it benefited non-equipped travelers. The evaluation methodology comprised twelve related studies categorized into naturalistic field studies, field experiments, and analytical studies. Data were collected from over 4,000 volunteer drivers using 100 specially equipped vehicles over a one-year period. The Rental User Study and Local User Study observed naturalistic usage by rental drivers and high-mileage residents, respectively. Field experiments, including the Yoked Driver Study and Orlando Test Network Study, empirically assessed performance metrics such as trip planning time, travel time, wrong turns, and subjective workload. Analytical studies included a Modeling Study that extrapolated performance for various market penetration levels (1% to 100%) and a Safety Study that integrated safety statistics across all data sources. The TravTek system featured three vehicle configurations ranging from basic local information access to advanced navigation with real-time traffic avoidance. Results demonstrated that the TravTek system was reliable and effectively helped drivers save substantial trip planning and travel time while avoiding congestion. Both visitor and local users utilized the system frequently, with the turn-by-turn guidance display and voice guide receiving high acceptance and yielding improved navigation performance compared to conventional methods. Users estimated the system’s value at approximately $1,000 per vehicle and indicated a willingness to pay for its features. The Safety Study concluded that the system was safe and suggested a small safety benefit for fully deployed systems. Furthermore, modeling results indicated that TravTek would benefit non-equipped vehicles sharing the road by reducing overall traffic inefficiencies, fuel consumption, and emissions. The significance of this research lies in its validation of in-vehicle navigation and traveler information technologies as viable components of Intelligent Transportation Systems. The study confirmed that such systems are useful, easy to use, and safe, providing a foundation for future deployment. It highlighted the importance of early evaluation integration and robust data collection in operational tests. The findings support the broader goals of improving transportation efficiency, safety, and driver satisfaction through advanced technology, while also offering specific lessons on system design, database maintenance, and operational management for future ITS implementations.
Key finding
The TravTek system was reliable, reduced trip planning and travel time, improved navigation performance, and was perceived by users as safe and worth approximately $1,000.
