IMPACT OF DRIVER INFORMATION SOURCES ON TMC OPERATOR PERFORMANCE REQUIREMENTS

Designers of traffic management systems now have a number of ways in which real-time traffic information can be disseminated to drivers. In addition to in-vehicle route guidance systems, candidate channels for data from the traffic management system to drivers include variable message signs, highway advisory radio, and dial-up (telephone) traffic information systems. Each of these candidates imposes certain performance requirements on TMC operators, and the combinations selected may impose additional requirements. Prototypes of support systems, designed to help TMC operators use and manage these information channels, were developed and evaluated. Results indicate that the density of information outlets has a major impact on the complexity of TMC operator tasks and on likelihood of operator errors. The findings also indicate that it is important to use a consistent method of interacting with each information outlet, rather than optimizing the individual interfaces for each type of outlet.
