According to National Highway Traffic Safety Administration statistics, 4,280 pedestrians and 618 bicyclists were killed in fatal collisions with motor vehicles in 2010, but the research and development department at General Motors is currently working on technology that may reduce the risk pedestrians and cyclists face when sharing the road with automobiles, as long as they’re carrying their smart phones.
Unlike recent pedestrian safety technology developed by Volvo — which recently announced plans to equip new automobiles with a pedestrian detection system and even an exterior air bag designed to protect pedestrians struck by the vehicle – GM’s new technology would use wireless internet connectivity to warn drivers approaching pedestrians of an impending collision.
With this technology, which GM researchers estimate may be available as early as 2017, smart phones and other Wi-Fi enabled devices carried by pedestrians would be able to communicate with nearby cars using the Wi-Fi Direct peer-to-peer wireless connection. Driver assistance systems using a sensor based object detection feature, similar to systems currently available in newer model vehicles, would be equipped with integrated with Wi-Fi Direct capabilities that could identify pedestrians and cyclists carrying smartphones equipped with a Wi-Fi Direct software app, also in development. Wi-Fi Direct, according to data provided by the Wi-Fi Alliance, is capable of transmitting reliably within a 200 yard radius and allows for connection times as fast as one second.
General Motors will be testing the device alongside many competing vehicle safety technologies in the National Highway Traffic Safety Administration’s upcoming vehicle to vehicle pilot program launching in Ann Arbor, Michigan next month.
Wireless vehicle to vehicle connectivity could have other applications besides passenger safety, GM researchers say, including transferring music files and contact information between vehicles.
The National Highway Traffic Safety Administration is currently testing the effectiveness of hands-free communication devices in reducing driver distraction, but the United States Transportation Secretary earlier this year suggested that states adopt legislation banning all forms of cellphone use behind the wheel with or with out a hands free adaptor. In February, the Transportation Department issued a set of guidelines for implementing built in communication systems in new vehicle models, which the department is urging automakers and wireless device manufacturers to adopt voluntarily. These guidelines include requiring the car to be in park before allowing drivers to access social networking or GPS navigation features and limiting any activity requiring input from the driver while the car is in motion to two seconds.
