Smart City technology developed by Applied Information (AI) has been deployed by the City of Atlanta to connect traffic signals, emergency vehicles and school zone safety flashers to the Internet of Things (IoT). It is part of the Renew Atlanta infrastructure improvement programme.

 

The AI technology includes the Glance TravelSafely smartphone app, which will connect drivers, cyclists and pedestrians to the infrastructure and each other to improve safety and mobility in the covered corridors. The deployment also includes the Glance Smart City Supervisory platform that allows cities to manage all their traffic and ITS assets on one web-based application.

 

“Through the everyday use of smartphones and other wireless technology, we see that a connected world just works better,” said Bryan Mulligan, president of Applied Information.

 

“Connecting people on the move to make them more visible to each other can help save lives and make commuting safer and more enjoyable.”

 

The AI Glance systems offer a number of smart city capabilities:

  • Emergency vehicles will receive priority and green lights at intersections that are flushed of traffic ahead of time. Smartphone app users in the area will receive notification of the approaching emergency vehicle;
  • Forty-six of the city’s intersections, five school zone beacons, nine pedestrian crossing beacons and 24 Traffic Communications Corridors will be connected using dedicated short-range communications (DSRC) technology and wireless cellular technology. The intersections will communicate with the city’s traffic control centre and enable traffic engineers to monitor and control the signals and beacons remotely;
  • Cyclists and pedestrians using the app are warned of a vehicle approaching at a dangerous speed and trajectory. In turn, drivers using the app are provided a message that a cyclist or pedestrian is ahead;
  • Motorists using the app receive a warning if they are about to run a traffic signal; Additionally, drivers are provided with the colour of the light at the traffic signal ahead and a countdown to change of colour;
  • Motorists with the app are given notification they have entered a school zone and a warning if they exceed the reduced speed limit.

The app is expected to be fully deployed and activated in January 2018. Anyone driving, cycling or walking in the Renew Atlanta coverage area can use the app which is free for Apple iPhone and Android users.
