Atlanta's I-285 to See Variable Speed Limit Signs

September 21, 2012

Atlanta's I-285, a perimeter route legendary for its congestion, will soon be seeing a new technology meant to help move traffic along.



According The Atlanta Journal-Constitution, the speed limit will eventually be raised from 55 mph to 65 mph. But drivers also will be seeing electronic speed limit signs that will vary depending upon congestion.

The Georgia Department of Transportation will be installing a technology that has been working well in Seattle that will increase or decrease the speed limit displayed by increments of 5 mph based on congestion levels.

The concept of variable speed limits is to attempt to smooth out the flow of traffic and reduce stop-and-go traffic behavior, which can cause accidents.

The construction to install the signs is anticipated to be completed in just a few months.

If the variable speed limit system is seen as a success then it could be expanded to other Atlanta roadways.
