Researchers from MIT and Princeton have collaborated and come up with a smartphone application that can predict whether the incoming traffic light would be red, green, or yellow once the driver reaches it. The SignalGuru app works by mounting the smartphone onto the car's dashboard. Then, the app captures images of traffic lights, which are analyzed based on the lights it flashed. Finally, the data is passed along to other nearby SignalGuru users.
The app can inform the driver how quickly he or she should drive to get through the next intersection.
