LAS VEGAS -- I'm sitting in the passenger seat of a Ford Taurus as the driver accelerates toward a green light. Suddenly, a red warning light flashes on the windshield and an alert tone sounds off. The driver hits the brakes, and another car goes flying by, across our path at the intersection.
While this was a demonstration at a fake intersection, with Ford drivers piloting each car, we were traveling at speed and there was certainly the potential for a crash. It was a recreation of a real-world situation that happens everyday at intersections.
However, the reason why the Taurus was able to alert the driver with light and sound, came down to a vehicle-to-vehicle communication system (V2V) installed in each car.
The V2V system includes GPS and a Dedicated Short Range Communication (DSRC) transceiver operating over the 802.11p standard. Each car was sending its GPS location out, including current path and speed, while receiving broadcasts from other cars in the vicinity.
The Taurus received the telemetry data from the car crossing our path, quickly calculated the potential for a collision, and alerted the driver to hit the brakes. Systems such as this are likely to be implemented in all cars, possibly by federal mandate, in the near future and will prevent collisions and fatalities.
