摘要:
This invention provides for a system 20 for speed measurement verification. The system 20 includes measuring means configured to automatically measure the speed of a vehicle 32 travelling on a surface 36 which includes a marker 34 at a predetermined distance 40 from the measuring means. The system 20 also includes a camera 28 directed, in use, at the marker 34 and a processor 26 arranged in electronic communication with the measuring means and the camera 28. The processor 26 is configured to automatically compare the measured speed of the vehicle 32 to a predetermined speed limit, and to automatically calculate a time delay to activate the camera 28 if the measured speed exceeds the speed limit. The time delay is calculated according to the measured speed of the vehicle 32 from the instance when the speed measurement was made, so that the camera 28 is activated when the vehicle 32, if travelling at the measured speed, reaches the marker 34. The camera is then activated to capture 18 an image after expiration of the time delay so that, if the measured speed is accurate, the vehicle 32 will be positioned proximate the marker 34. This captured image then shows the vehicle 32 relative to the marker 34 which image is then able to serve as verification of the accuracy of the measured speed.
