The present invention relates to a traffic signal system for a road, and more particularly, to a traffic signal system for a road that can smoothly pass a vehicle at an intersection.

In general, the intersection where the roads cross each other is a multi-road crossing with 5 or more forks, a four-way crossroad with four forks, and a sperm crossing with three forks. Alternatively, it means an area that extends the curb side of a road where two or more roads cross at right angles or close to each other, such as a vortex intersection, or is surrounded by a connected line, and the roads cross each other even if they are not at right angles. By doing so, areas that are likely to cause vehicle collisions are included in the intersection. When a driver of any car wants to turn right at an intersection, he must turn right, slowing down the right edge of the road in advance. In addition, when you want to turn left, you must make a left turn using the inside of the center of the intersection while slowing down the center line of the road in advance.

At these intersections, traffic lights that guide traffic signals of vehicles and traffic lights that inform pedestrians of traffic are installed.

Conventionally, when a signal of a traffic light at an intersection changes, a problem occurs in which a vehicle driver does not properly recognize it and thus a signal is violated, thereby causing a traffic congestion problem. In addition, since the traffic lights installed on the pedestrian crossing are installed in a position that is difficult for the driver of the vehicle to recognize, when the traffic lights of the pedestrian crossing are green, the vehicle stops at the pedestrian crossing. Therefore, there is a need to improve this.
