A human factors study on graphic-aided dynamic message signs
Date of Original Version
This paper describes a human factors study that examines the effects of graphic-aided dynamic message signs (DMSs) on drivers' comprehension of sign messages. Extensive textual messages displayed on overhead-mounted full-size DMSs could be difficult for drivers to comprehend while driving at highway speed. Since graphics are considered more user-friendly than texts, this study explored the use of graphics on DMSs and assessed its effects on human drivers. A questionnaire survey was given and a lab simulation was carried out to measure drivers' responses to the test DMS messages. Results of the lab simulation were reported with a drawn conclusion.
