Red X

A powerful solution for managing and enforcing lane usage. The variable sign automatically alerts drivers to lane closures and speed changes – giving them time to adjust their driving to any altered conditions ahead – and the Red X solution automatically  captures  enforceable violation data for drivers who do not comply with the signs (Red X).

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.
