Atlanta unveiled a stretch of “smart” road Thursday that could help usher in an era of driverless cars and transform the city’s transporta­tion infrastruc­ture.

The North Avenue Smart Corridor Project – which stretches from the Coca-Cola headquarte­rs and Georgia Tech to the Ponce City Market – includes adaptive traffic signals, high-definition cameras and other technology that advocates say will improve safety and speed traffic on a busy eastwest street.

Don’t expect to see fully auton

omous vehicles driving down North Avenue any time soon –

there are still technologi­cal and legal hurdles to overcome. But if all goes well, North Avenue will become a model street for Atlanta and the nation.

“Atlanta will become a national leader in the smart-cities movement,” Mayor Kasim Reed said at a ceremony at Ponce City Market Thursday.

The $3 million project brought several new technologi­es to the 2.3-mile stretch of North Avenue. Among them:

Adaptive traffic signals, which monitor traffic flow and can make real-time adjustment­s. By allowing the lights to adjust

their timing as needed, the new technology could cut commute times along a corridor that carries nearly 29,000 vehicles a day in some spots.

Video surveillan­ce cameras, which monitor pedestrian­s and

bicycles as well as vehicles. Among other things, the cameras could detect pedestrian­s crossing the road, allowing a traffic signal to wait just a little longer to turn green so they can finish crossing.

“Connected vehicle systems” technology that could allow traffic signals to communicat­e with autonomous vehicles or with drivers’ smart phones. Such technology might tell you to slow down as you approach an intersecti­on so you can catch a green light, for example. Or it might alert you if you’re speeding through a school zone.

A system that allows emergency vehicles to preempt traffic signals and speed through intersecti­ons.

These and other technologi­es could save lives and substantia­lly reduce traffic congestion, according to Georgia Department of Transporta­tion Commission­er Russell McMurry.

He said the North Avenue project is just one example of how the Peach State is embracing new traffic technologi­es. Georgia already has more than 300 adaptive traf

fic signals– most of them in Cobb County and Sandy Springs — the most of any state.

“We want to be the early adopt- ers,” McMurry said.

Atlanta already is using such technology to manage traffic at big events. Typically, it can take 90 minutes to empty a parking garage after an event at Philips Arena. But such technology allowed the city to cut that time in half after a recent event, accordingt­o Faye DiMassimo, general manager of

the city’s Renew Atlanta infrastruc­ture bond program.

Georgia Tech plans to analyze data from sensors along North Avenue to help Atlanta set benchmarks for congestion relief and

other areas.

The informatio­n will be used to help create similar corridors elsewhere.

Campbellto­n Road in southwest Atlanta and Buckhead Loop are among the streets that could see such technology in the near future.
