Your cell phone could keep you safe from being hit by a car in the future when walking or bicycling.
Researchers at the Technische Universitaet Muenchen (TUM) in Munich, Germany have developed technology that enables the computer system in cars to see the location of pedestrians and cyclists – even while they’re not visible to the eye.
Pedestrian’s and cyclist’s cell phones will serve as transponders that will send a signal to a car’s onboard positioning systems. The system will compute the projected trajectory of the person on foot or a bike and initiate an emergency braking sequence in case a pedestrian or cyclist moves into the path of a car.

Here’s more on how it will work.
