The Cobb County Department of Transportation has activated six dynamic message signs throughout Marietta and Smyrna.
These signs are on routes that converge on the Interstate 75/U.S. 41 corridor within the greater Cumberland area and help guide guests to SunTrust Park and The Battery Atlanta.
Installed on Cobb Parkway, South Marietta Parkway, Roswell Road and Spring Road, the full-color LED signs provide travel-time information for common destinations and the congestion level for specific routes in real time, according to a county statement.
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, with green indicating almost free-flow speeds, yellow for moderate speeds and red for slow conditions.
Public service announcements and information about incidents, construction and special events also will appear on the signs, all allowing motorists to choose less-congested routes.
This state-of-the art technology offers Cobb County another way to reduce congestion and improve the travel experience, according to CCDOT Director Jim Wilgus.
The travel-time messages depend on real-time data collected by a recently expanded travel-time system which now covers many major arterials within Cobb County and freeways in the Atlanta metro area and comes from detectors that collect anonymous electronic addresses from motorists’ Bluetooth and WiFi-enabled mobile devices.
