The Rental User Study and Local User Study were conducted as part of the TravTek Operational Test Evaluation. TravTek was an operational field test of an advanced traveler information and traffic management system (ATIS/ATMS). As part of the test, 75 TravTek equipped vehicles were rented to Orlando visitors. Other TravTek equipped vehicles were supplied to Orlando residents who were selected in part because they compile above average mileage in their daily driving. There were 2,896 TravTek rentals that averaged 4 to 6 days. Fifty-one local users were each given use of a TravTek vehicle for approximately 2 months. The focus of these evaluation studies was to obtain user perception and performance data related to use of system components in the TravTek vehicles. The vehicles were equipped to provide route planning, route guidance, and a data base of local services and attractions. The in-vehicle system included moving map and simplified turn-by-turn guidance displays supplemented by a synthesized voice guidance and traffic report feature. Questionnaires, debriefings, and automated in-vehicle data logs were used to gather evaluation data. Measures described in this report include: perceptions of utility, ease of use, safety, driver workload, frequency of use of system functions and features, and estimates of willingness-to-pay for the TravTek system as a whole, as well as for selected features. Both rental and local users reported the route planning and route guidance features of the TravTek system to be useful and easy to use. Users reported that they felt more attentive and less distracted when driving with the TravTek system compared to driving in similar situations without the system. TravTek was used on more than half of all trips. Renters with route planning and route guidance capabilities used those capabilities on more than half their trips. Local users also made extensive use of the route planning and route guidance capabilities. In route guidance, rental users drove most of the time with the simplified Turn-by-Turn Guidance Display with the synthesized voice supplement turned on. Although local users expressed a slight preference for the moving map Route Map display without the supplemental voice, they also used the Guidance Display with voice supplement on more than other display options. Users estimated that they would be willing to pay about $1000 for a system such as the one they drove. Users also indicated that they were willing to pay the most for navigation, route planning and route guidance features, and somewhat less for real-time traffic information and local information data bases.
