Description

Sidewalk blocks installed around traffic lights}

The present invention relates to a sidewalk block installed around a traffic light that is installed adjacent to a plurality of braille blocks installed on a roadway around the traffic light, which has a simple structure, thereby reducing manufacturing costs and improving constructability.

In general, sidewalk blocks are installed in India where people come and go to separate them from roads. Sidewalk blocks made of cement or rubber are used.

Recently, a product that can transmit better walking information to pedestrians by constructing a reinforced transparent window on the sidewalk block and letting a lamp or LED light illuminate inside has been developed and applied.

However, the conventional light emitting sidewalk block has a complicated internal structure and is configured to emit light separately without being associated with traffic light.

On the other hand, if you look at pedestrians these days, the risk of safety accidents is increasing rapidly near pedestrian crossings while walking while walking while looking at your smartphone. A braille block is installed as an example of a safety guide to compensate for this, but the reality is that it is not well observed. Therefore, the present applicant proposes a sidewalk block of a structure that can significantly reduce manufacturing costs because the internal structure is considerably simpler than the previous one, and can function as a safety guide for pedestrians by emitting light in connection with traffic lights.
