DUNWOODY, Ga. — Dunwoody recently released a tour of its new Traffic Control Center in City Hall.
The traffic center connects to all the traffic signals within the city limits and allows engineers to adjust signal timing to improve traffic flow.
“Now we’re able to communicate with and adjust remotely all the signals in the city,” Dunwoody Public Works Director Michael Smith said. “Before this project, we could communicate with only 20 of our 60 signals.”
The improved signal control is the result of two projects that extended the fiber-optic signal communication network and added video cameras and vehicle detection at many intersections.
“The cameras are not red-light cameras,” Smith said. “These are purely used to monitor traffic conditions at each intersection. We can look at the video along with the cycle of the signal in real time to troubleshoot and make timing adjustments.”
One of the projects was led by the Perimeter Community Improvement Districts (PCIDs), which contributed $370,000 and secured $1.5 million in federal congestion mitigation and air quality funding through the Atlanta Regional Commission and the Georgia Department of Transportation.
This program focused on upgrading and modernizing signals in the Perimeter area of Dunwoody, Sandy Springs and Brookhaven and connecting the existing fiber network to Dunwoody’s Traffic Control Center.
Dunwoody’s project complemented the work of PCIDs by extending the signal communication network to other parts of the city at a cost of $1.1 million, with federal funding covering 80 percent of the cost.
The Traffic Control Center allows engineers to monitor congestion, look for incidents and adjust signal timing to improve traffic flow.
The Traffic Control Center is not manned at all hours, but traffic engineers are on-call and automatically alerted when signals malfunction. They’re able to work on the system remotely. GDOT also supports the center with a team of engineers who work on traffic issues in Dunwoody, Brookhaven and Sandy Springs.
