Mobile Phone Signals Monitor Traffic Flow

Share

Depending how you look at it TrafficAid is a useful or a sinister development in road traffic management. Developed by engineers at IntelliOne in Atlanta. TrafficAid monitors traffic flow by picking up and triangulating mobile phone signals. All mobiles, whether they’re being used or not are constantly sending out signals that tells the network where they are and this information can be used to accurately plot the number of vehicles, and how fast they are moving on a stretch of road. Unlike existing systems, which rely on buried sensors, cameras or detectors, TrafficAid requires no additional infrastructure. In case you are concerned about privacy IntelliOne claim that no personally identifiable data is retrieved fro the phones being monitored, though it hardly seems worth worrying about given the number of cameras watching your every move these days.
