Automated speed enforcement in England has increased capacity by 5 to 10 percent.
According to England officials, automated enforcement is important in maintaining compliance with variable speed limits. Detectors identify vehicles exceeding the speed limit while cameras mounted on overhead freeway signs photograph the license plate. The system has shown a very high compliance rate with speed limits, an increase in capacity by 5 percent to 10 percent, and a 25 percent to 30 percent decrease in rear-end accidents on the approaches to queues on the freeway.
