A traffic system for alerting a driver of a vehicle to a traffic sign includes a sensor and a control unit. The sensor may be an image sensor and the control unit may comprise a graphic processing unit (GPU) to detect the optical flow of objects in the captured images so as to distinguish moving vehicles from non-moving objects. The speed of vehicles may be detected such that the system may (1) activate lights to warn a driver if he is traveling too fast or (2) display the speed to either the driver or a police officer. The system may also be implemented and used as a geographic border monitoring system.
