Completed Projects

Use of Color Changeable Message Signs - Current Practices and Research

This project will synthesize literature, research, and practices from the limited number of states using colors on CMS. This project will identify a range of issues agencies may consider and the possible implications with integrating color in the display of different types of messages (e.g., combination of text and symbols, symbols only) on color CMSs.  The reports generated by this project may assist with identifying issues to address in future efforts to develop technical resources, procedures, policies, or research in support of the use and display of messages on color CMSs.
