Commuters appear to be adjusting quickly to the new traffic lights that control the flow of traffic onto and off of the top end Perimeter, according to the number of complaints logged by state transportation officials.

This week, only one complaint has been received, said Monica Luck, a spokeswoman with the state Department of Transportation.

About 50 complaints were filed a week ago, when the traffic lights were turned on. That's not to say the adjustment has been easy for drivers whose flow onto and off of the Perimeter is now controlled by traffic lights. Some motorists have reported delays of more than an hour.

"We did have a couple of days where it was not just a learning curve for the public, but for us as we made timing adjustments," Luck said. "Sometimes we've turned lights off to let the queue clear out."

DOT can adjust the timing of lights by remote controls.

About 270,000 vehicles a day travel the north side of I-285, DOT says.

The number of complaints about the new lights on the Perimeter is a far cry from those received when DOT re-striped the northbound I-85 exit ramp to Ga. 400 in June 2004. DOT logged more than 1,500 complaints in one six-hour period. The ramp was re-striped from two lanes to one to end illegal line-cutting by drivers.

The street lights, called ramp meters, have been installed at several ramps on I-285 from Riverside Drive to Buford Highway.
