Impacts of Dynamically Displaying Messages on Changeable Message Signs

This project assesses the impacts of dynamically displaying messages on changeable message signs (CMSs) and makes recommendations for updates to the Manual on Uniform Traffic Control Devices (MUTCD) regarding design, programming, and operation of such applications. The objectives of the research effort are to: (1) Conduct human factors studies to determine the effects of dynamically displaying messages on CMSs; (2) Develop preliminary guidance to practitioners for dynamically displaying messages on CMS; and (3) Identify and recommend changes or new provisions to the MUTCD. This project builds upon the research conducted under the TMC Pooled Fund Study project Changeable Message Sign Operation and Messaging.
