METHOD AND SYSTEM FOR MEASURING THE SPEED OF A VEHICLE

A system for measuring the speed of a vehicle includes: one or more cameras (200) for capturing images of vehicles (100) on a road (50); timing means for timing the capture of the images; a processor arranged to: identify in the captured images a feature (150) of the vehicle; calculate the size in pixels of the feature (150) of the vehicle in two or more of the captured images; and determine the speed of the vehicle (100) based at least in part on the calculated sizes and the times at which each image was captured.
