Road sign information

Operation principle of road sign information

The road sign information uses a video camera with algorithms to detect and classify round, triangular and rectangular road signs, including the start and ends of stretches where speed limits are in force, or where passing is prohibited. It also recognizes “no entry”, “stop”, “right of way” and “road works” signs. The road sign information also classifies relevant supplementary signs, such as time limits, signs applicable only to specific vehicle types and turn arrows.

When the assistant identifies a road sign, it shows this information using icons in the dashboard display. The system reliably detects road signs, whether they are sited on actual signs, variable message systems or gantries.
