Abstract:
1. A system for field or onsite use in determining a failure of a vehicle to stop at a traffic sign or signal and capturing images of the vehicle, comprising: a laser-based speed detector determining a speed of a vehicle in an enforcement window adjacent the sign or signal and in response, generating a speed signal; a camera aligned with the speed detector capturing and storing an image of the vehicle, wherein the camera is adapted for operating in response to an image capture signal; and a portable field processor communicatively linked with the speed detector and the camera, wherein the portable field processor receives the speed signal from the speed detector, compares the speed signal to a capture speed threshold that is calculated by the processor as a percentage of a posted speed limit for a road lane passing through the enforcement window, and when the threshold is determined to be exceeded, transmits the image capture signal to the camera.
