Traffic sign recognition

Traffic sign recognition is a technology by which a vehicle is able to recognise the traffic signs put on the road e.g. "speed limit" or "children" or "turn ahead". This is part of the features collectively called ADAS. The idea is to improve road safety by assisting the driver. It may happen that the driver is tired or misses the road sign. This feature will recognise the road sign and accordingly inform the driver to go slow or take a turn. The technology is being developed by many OEMs such as Ayonix and Continental.

These first TSR systems which recognize speed limits were developed in cooperation by Mobileye and Continental AG. They first appeared in late-2008 on the redesigned BMW 7-Series, and the following year on the Mercedes-Benz S-Class. Currently these systems only detect speed limits.

Second generation systems can also detect overtaking restrictions (introduced in 2008 in the Opel Insignia, later followed by the Opel Astra and the Saab 9-5; also available on the 2011 Volkswagen Phaeton)
