The Georgia Department of Transportation, a partner in the Ashford Dunwoody DDI, entered the project in the regional competition where it was selected a winner in the Ahead of Schedule, Small Project category. 

Now the DDI is competing for the Grand Prize and the People’s Choice Award. The Grand Prize will be awarded by a panel of judges. The People’s Choice Award will be decided by popular vote of the general public. 

Williams appeared before Sandy Springs City Council, Tuesday to discuss the success of the Perimeter Traffic Operations Program. The program focuses on better timed traffic signals and three major roadways - Ashford Dunwoody Road, Perimeter Center West/Abernathy, and Peachtree Dunwoody Road. Williams says it has already shown a 40 percent improvement in traffic flow and more 200,000 hours saved in vehicle travel time. Part of those improvements are a result of the completed Diverging Diamond Interchange. (Williams and her team made a presentation to Dunwoody City Council on Sept. 10.)

“I think I’ve noticed that the lights are more synchronized than they were before,” said Mayor Eva Galambos. “Especially on Peachtree Dunwoody Road.”

Dunwoody, Sandy Springs, and Brookhaven, along with the PCIDs and DeKalb County are participants in PTOP, which was funded by the Georgia Department of Transportation for $2.78 million.  

PTOP’s hub is located at the Sandy Springs Traffic Management Center in the City Hall complex, but technicians can retime signals from wherever they are.
