Unlike other ITS deployments around the world, Georgia Navigator almost exclusively uses video detection cameras to gather traffic flow data, as opposed to traditional sensors embedded in the pavement.
Additionally, a portion of the system (Georgia 400[1] and parts of I-16, I-75 and I-85 outside of Atlanta[2]) receives traffic flow information from floating car data gathered by anonymously tracking cell phones.
Traffic sensors are installed on official evacuation routes, but are only activated during a hurricane approaching the Georgia coast or eastern Florida panhandle.
Unlike early systems which used induction loops, the new meters will employ video detection cameras to sense the density of traffic and allow an optimized rate of vehicles to proceed onto the freeway.
The local road devices also feed into the Georgia Navigator system and are controlled by a common software platform.
