Federal highway officials think they've found a way to prevent thousands of traffic accidents every year: "smart intersections" that warn drivers they're about to run a red light or smash into a truck, according to the Associated Press. Government drivers demonstrated June 24 at the nation's first test intersection just what the intersection of the future will be able to do, according to AP. A car speeds toward an intersection, about to collide with a van. Sensors spot the car as it approaches the red light and emit a signal to the car, which triggers a high-pitched beep and a red light on the dashboard that says, emphatically, "STOP." Federal Highway Administration officials believe it will prevent thousands of traffic accidents every year, according to AP. Much testing remains to be done, and drivers probably won't see smart intersections for another five years, say highway officials.
