AirSage determines traffic jams by the number of mobiles on the roads

Until now, there were not so many good vehicles for all drivers, allowing in real time to monitor road accidents and traffic jams. The message about the situation on the roads on the radio is not constant, and the local authorities for the most part refuse from sensors that allow real-time monitoring of road congestion, but costing incredible money.

AirSage from Atlanta recently announced that it has found a way to solve this problem. She developed and uses her own software algorithms that measure the number, speed, and density of cellphone signals in cars driving along the road. The greater the density of signals, the more loaded the road. In 46 cities in the United States, AirSage receives a continuous stream of data from radio signals from the largest US telecommunications company, Sprint Nextel. The company then looks at the signal density and vehicle speed to determine traffic jams.

AirSage now sells real-time traffic congestion information to local governments, radio and television stations in 46 North American cities.
