Motorists on Ga. 400 likely have noticed the colorful pipes being installed along the shoulder of the busy corridor in south Forsyth.

Those pipes, said state Department of Transportation spokeswoman Teri Pope, will house the cable and wiring for automatic traffic management and intelligent traffic systems, both of which use cameras to monitor conditions.

Pope said the technology, which currently stops at McFarland Road, will extend past Hwy. 20/Exit 14 by July 31.

For travelers, that means they can then access real-time traffic information, including trip times, along those 7.7 miles via Georgia’s 511/Navigator system.

“The technology uses several types of cameras and sensors to gather information that is shared on our Web site,” Pope said.

Marietta-based World Fiber Technologies is handling the $1.65 million project. Once completed, motorists can dial 511 from cell phones, visit www.511ga.org or use the smartphone application to get traffic updates. All three options are free.

Pope said “getting real-time traffic information to motorists allows them to make better choices before they get stuck in traffic.”

“We see it as a form of customer service, getting motorists all the current data so they can decide to leave work a little early, or if they have time to have another cup of coffee,” she said.
