Description

Smart bollard system for pedestrian safety

The present invention relates to a smart bollard system for pedestrian safety, and more particularly, to a smart bollard system for pedestrian safety implemented to promote pedestrian safety by adding a smart function to a bollard installed in a crosswalk. .

In general, bollards are installed in road crossings, child safety zones, etc. to block the entry of vehicles to safely protect pedestrians from vehicles.

These bollards are constructed by molding various materials such as stone, concrete, metal, or plastic in the form of rods and burying them in the ground, or fixing them to the ground using a fastening means such as an anchor.

Most of these conventional bollards are designed in an aesthetic form, so their appearance is beautifully decorated, or because they can only be used with extremely limited functions to simply prevent vehicles from entering, their utility is largely insufficient, and it is uneconomical compared to their utility. There is this.

In addition, there are cases where bicycles, motorcycles, and small vehicles enter the gap between the bollards, so there is a problem that accidents often occur.

In addition, there are frequent problems that pedestrians run into bollards while walking while looking at their smartphones, or accidents occur while crossing the crosswalk without recognizing it even though the crosswalk traffic light is red.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the purpose of derivation of the present invention or acquired during the derivation process of the present invention, and it cannot be said that it is necessarily known technology disclosed to the general public before the filing of the present invention. .
