Red light cameras can cause traffic accidents at intersections to drop by 25 percent, according to a new study by the traffic scientists at Texas A&M’s Texas Transportation Institute.
Red light cameras are installed at 275 intersections across Texas. They automatically snap photos of cars that run red lights. The drivers are sent a ticket in the mail.
The traffic-ologists at TTI examined 11,000 crash records from all those red light camera intersections. They found that red light crashes dropped by a quarter, and right-angle or “T-bone” crashes plummeted by 32 percent.
