TravTek is a joint public sector/private sector operational field test of an advanced driver information and traffic management system. The year-long project will be operational in the greater Orlando area in 1992. In addition to the demonstration of navigation and traffic management technology, a major goal of TravTek is to evaluate project objectives and answer questions about driver behavior. The data collected will be used to examine system benefits and costs in a fully deployed system. The foci of this paper are 1) the concept of TravTek as a person-machine system, 2) the process of planning a comprehensive research program and 3) an overview of the planned evaluation approaches. Although the TravTek evaluation will not be completed until after 1992, it is hoped that this status report will assist in the research planning efforts of future Intelligent Vehicle Highway System (IVHS)/Advanced Driver Information System (ADIS) demonstrations.
