Travtek Evaluation Yoked Driver Study Final Report PDF Download

The Yoked Driver Study was 1 of 12 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 completed 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 the Yoked Driver Study was to evaluate the value of real-time traffic information, route planning, and route guidance to (a) trip efficiency, (b) navigation performance, and (c) driving performance. The study also examined willingness-to-pay, user perceptions of the system, and user recommendations.
