GM wants to use smartphones to prevent pedestrian fatalities

GM announced today that its researchers are currently working to use Wi-Fi Direct technology to detect smartphone-carrying pedestrians and bicyclists. The automaker hopes to use this technology to reduce traffic fatalities by alerting drivers with a visual or aural notification when a pedestrian is nearby. Wi-Fi Direct allows the detection of nearby devices in about one second instead of the seven or eight required by traditional wireless systems, and GM’s goal is to integrate this technology into previously existing driver alert systems.
