Smartphones are too often a colossal distraction to motorists, but Honda sees a way of using them to protect pedestrians from inattentive drivers.

The automaker hopes to tap into pedestrians' phones to alert passing drivers to their presence. The technology – dubbed Vehicle-to-Pedestrian – uses a smartphone's GPS and dedicated short range communications (DSRC) to warn drivers when a pedestrian steps out from behind a parked car or other obstruction. A light flashes on the dashboard to tell the driver of an approaching pedestrian, while the hapless walker gets an alert on their smartphone.

The DSRC system can be deployed through a dedicated app with the technology operating on the 5.9GHz band set aside for automotive applications. Honda's not alone in pursuing this. General Motors is using the same tech to develop its own pedestrian detecting technology. But Honda is taking it a step further. In addition to the pedestrian detection tech, Honda is also testing Vehicle-to-Motorcycle systems using the same DSRC to alert drivers of a motorcycle outside their field of vision.

Honda is joined by several other automakers working with the University of Michigan through the Connected Vehicle Safety Pilot Program conducted by the U.S. Department of Transportation on the technology, and if all goes well, these systems could be deployed in the next several years.
