# Applied technology and service overview

ㅇ Configuration of the device-4 kinds of signals can be displayed because the signals of the existing 4-way traffic light are built into the 1-way. 

ㅇ Features of the device ~ Display (count-down) the remaining time of the green signal with a yellow signal in conjunction with the main traffic light. )

ㅇ Characteristics of device ~ Display (count-down) red and green signals in conjunction with main traffic lights.

ㅇ The traffic light display control system according to the auxiliary traffic lights is a system that can be controlled by the central control station and controls the display of traffic lights installed on each road. As the first display unit, the auxiliary traffic lights are used as the second display unit. A memory unit storing a command value for blinking each indicator of the main traffic light, the auxiliary traffic light, and the main traffic light used in the signal system at predetermined time intervals, and the auxiliary traffic light and the main traffic light according to the command value stored in the memory unit And a control unit for controlling to blink at a predetermined time interval, wherein the auxiliary traffic light is installed above the main traffic light, and the auxiliary traffic light is composed of first to fifth indicator lights, and first to The fifth indicator light is a technology characterized in that it is sequentially lit as a yellow signal for preventing entry into an intersection on a road.

In addition, in the display control system of a traffic light according to an auxiliary traffic light, when the yellow light of the main traffic light is lit, the first to fifth indicators of the auxiliary traffic light are lit yellow at the same time, and when the main traffic light is a red light, It is a technology characterized in that when the main traffic light is lit in red and green, it lights in green at the same time.​
