Red X uses Optical Character Recognition (OCR) based video analytics (or a direct-connected system) to recognise Red X warning signs that alert drivers of a closed motorway lane and fine those who disobey.
With an OCR-based system, the contextual cameras monitor changes to the variable message signs and provide confirmation of correct sign displays. Alternatively, a direct signal can be fed from the sign controller into the camera system. In this case, the remote camera provides verification of correct sign displays.
The Red X application is part of the Intelligent Motorway platform which allows for the simultaneous operation of Red X and speed enforcement.
When a sign displays a Red X, the system identifies the lane(s) displaying the Red X and enables lane closure enforcement. Upon detection of a Red X violation, a new incident type is created and processed in the same way as speed violations.
