Abstract:

Changeable message sign (CMS) messaging is an important tool for distributing traveler information to drivers. Careful CMS message selection can help drivers make informed travel decisions and increase the safety and usability of roadways—particularly during nonrecurring events. The current approach is designed to help CMS operators construct CMS messages about nonrecurring events by using research-backed practices. This report introduces the rationale for using CMS messages as well as information on CMS provisions, message construction, and ways to cultivate trust in CMSs. The report also includes a number of decision trees designed to help CMS operators select the specific message components and phrases to include in a CMS message during different nonrecurring events. Finally, the report provides examples of how to use the decision trees to create a final, complete CMS message by using a CMS Message Construction Worksheet. The goal is to improve the safety and flow of the transportation system during nonrecurring events by providing information on documentation of specific CMS messages that effectively promote desired changes in traveler behavior.
