Smart-Phone App Warns Pedestrians of Oncoming Cars - Technology Review

Sign of the times

Researchers at Dartmouth College and the University of Bologna in Italy have developed an Android app that uses the camera on a smart phone to detect oncoming traffic.

The app relies on machine-learning and image-recognition algorithms to identify the fronts and backs of vehicles, and takes into account varying light conditions, phone tilt, and blur. When WalkSafe detects a car approaching at 30 miles per hour or faster, it vibrates the phone and makes a sound to alert the distracted user.
