“They’ve adopted adaptive traffic signals. And what they’re trying to do is get a higher percentage of the lights to be green,” Mulligan explained.
Engineers at Georgia Tech study the data this technology produces to see if indeed and how much this connected innovation helps. With more connected technology, data is more precise and traffic planning has a better baseline.
The convenience of the Travel Safely App alerting drivers, should simply decrease traffic, by boosting driver awareness, Mulligan said. Commuters will be much more alert when a light turns green, as many pause illegally at lights to check their phones. “If we just save one or two seconds in the light going green, we’ll have created 5-10 percent more capacity on the roadway, without any additional cost.”
Both the cities of Atlanta and Marietta are outfitting some firetrucks and firehouses with this smart technology, to increase their response time, without shelling out hundreds of thousands of dollars to build new firehouses. MARTA is exploring this technology for both its buses and the Atlanta Streetcar, which MARTA will soon begin operating. More green lights, means better service on all fronts.
North Avenue also has smart pedestrian signals, so those crossing the street do not have to press a button. And Mulligan revealed that this technology will speak to motorists when they are approaching occupied crosswalks and when cyclists are nearby.
A few states are working with the U.S. Department of Transportation to develop these smart technologies, but Atlanta’s project is groundbreaking, as they are working on a local level with grant money.
“What Atlanta has done is seize the initiative of a city that is trying to take control of its own future, by producing some grant money,” Mulligan said adding that this leads businesses in the autonomous technology industry to choose Atlanta. “I can confidently say that Atlanta is leading the nation with the deployment of these smart technologies to attract commerce.”
Whether smart lights are communicating with mobile devices or self-driving cars, the North Avenue smart corridor should improve traffic and safety, as more people connect with it. A.I. is beta-testing the app now and both it and the corridor should be in full operation in early 2018. Mulligan explained that the app runs in the background and is fully functional while other apps, like WSB’s Triple Team Traffic Alerts App, also guide drivers.
Mulligan said he believes that if the North Avenue corridor is successful, that Atlanta will equip every intersection the same way. Other cities and counties are also exploring the technology.
