Patent Images
1. An apparatus for informing a road condition of a road to a driver of a vehicle driving on the road, the apparatus comprising:
- a detecting unit configured to be provided at a detection position on the road and to detect the road condition near the detection position;
a light emitting unit configured to be provided at the detection position and to emit a light; and
a control unit that controls a light emission of the light emitting unit based on detected road condition,wherein the detecting unit is provided in correspondence with a single lane of a road having a plurality of lanes, andwherein the light emitting unit is operative to provide a flashing light with a variable frequency that is controlled on the basis of an output of the detecting unit to represent a respective one of a plurality of road conditions.
