How Do Average Speed Cameras Work?

Answer

Average speed cameras work by detecting the speed of vehicles by using piezo electronic detectors that are fixed onto the road surface. These piezo detectors repel slightly when a car is driven over the detectors, which then triggers an electronic device that precisely measures the haste of a vehicle. If the speed of the vehicle goes beyond the legal limit, then a digital picture will be taken of the offending driver

Average speed cameras are usually placed at a distance referred to as a speed controlled zone. When a vehicle enters this zone, the cameras, which are loaded with Automatic Number Plate Reading (ANPR) digital technology, take pictures of the vehicles number plate and the speed. The same happens when the vehicle stops.
