Failure to see a road sign displaying the permissible maximum speed can be expensive and, especially for people who rely on their driving license for their work, the consequences can be unpleasant.
Traffic Sign Recognition has a display on the instrument panel to remind drivers of the current speed limit. This is achieved through multiple use of the same camera which is also used for the Lane Departure Warning system. When combined with high-performance software, it can also recognize speed limit signs.
Digitized speed limit information of the on board navigation system will be incorporated to be prepared for roads not assigned with speed limit signs.
