Date of Original Version



A human factors study was conducted to study the age effect on drivers' comprehension of dynamic message sign (DMS) messages. A questionnaire survey and a video-based driving simulation were administered to sixty subjects of all ages to assess their preferences of and responses to various DMS displays and formats. Survey results found that elder drivers' preferences were not significantly different from those of younger drivers' but simulation indicated that elder drivers responded slower and less accurately. Correlations and discrepancies between the survey and simulation results were discussed. Suggestions were prepared to aid the development and deployment of driverfriendly DMS messages.
