Camera-based traffic sign detection is able to identify, interpret and graphically display to the driver road signs, such as speed limits. They can be shown on a driver information system, a multimedia console or a heads-up display. A camera does have some physical limitations when it comes to recognising traffic signs. Processing and recognition of detected road signs require extensive calculation algorithms.

By interconnecting various systems it is possible to implement common functionality over a variety of separate sub-systems.  This includes pre-emptive speed control which actively utilises information from traffic sign recognition systems.
