Description

{Safety signposting system for curved road}

The present invention relates to a safety indicator system for curved roads installed on one side of a curved road so as to inform the driver of the danger of a curved road, thereby reducing an accident risk.

Generally, safety signs provide information by using easily recognizable symbols, pictures, letters, etc. to notify dangerous places, materials, and other things.

On the other hand, among the various types of safety signs, traffic safety signs indicate caution, regulations, or directions about road traffic. In areas where the risk of accidents is high, the driver can recognize the safety signs more effectively, .

Accordingly, in the case of a curved road in which it is difficult to confirm whether or not a traveling vehicle opposite to the one-way traveling vehicle is entering, a safety indicator for a curved road for notifying a danger, a mirror for allowing entry of the opposite vehicle Respectively.

However, the mirror described above has a problem that visibility is low at nighttime driving.

On the other hand, as a related literature, Korean Utility Model No. 20-0223936 entitled " Traffic sign for a curve section of a road " is disclosed.

The preceding document is characterized in that, in a curved section requiring deceleration and safe driving, a specified speed sign and a curved road sign are attached to a single end, thereby reducing the number of traffic signs and facilitating installation.

However, even in the above-mentioned prior art, it is difficult for the driver to intuitively confirm whether or not the opposite vehicle enters the vehicle, and in particular, there is a problem that the risk situation can not be reduced at nighttime driving.
