Georgia transportation officials have approved a plan to install technology that will allow speed limits to change on a metro Atlanta interstate depending on traffic conditions.

The state Department of Transportation decided Thursday to move ahead with plans for the electronic speed limit signs on the northern part of Interstate 285.

DOT spokeswoman Jill Goldberg said signs will adjust the speed limit based on such factors as weather conditions and rush hour traffic. She said the technology is a way to keep traffic flowing evenly.

The signs will be installed north of Interstate 20 on both sides of I-285. The speed limit will increase from 55 to 65 mph on the entire perimeter, with the signs giving officials the ability to slow speeds down when conditions warrant.
