Cobb DOT activates dynamic message signs featuring travel times

The Cobb County Department of Transportation (CCDOT) has activated six dynamic message signs throughout Marietta and Smyrna. The signs are located on routes that converge on the Interstate 75/U.S. 41 corridor within the greater Cumberland area and play a role in guiding patrons to SunTrust Park and The Battery Atlanta.

The full-color LED signs installed on Cobb Parkway, South Marietta Parkway, Roswell Road and Spring Road provide travel time information for common destinations and indicate the congestion level related to specific routes in real time. Travel times on I-75 and Cobb Parkway appear in digits that are green, yellow or red, depending on the average speed of the roadway. Green digits indicate near free-flow speeds, yellow digits indicate moderate speeds and red digits indicate slow conditions. Public service announcements as well as information related to incidents, construction and special events also will appear on the signs. These messages allow motorists to choose less congested routes.
