KR960035373A - Traffic light standby time display device and control method - Google Patents

Abstract

The present invention relates to a traffic light standby time display device and a control method thereof capable of visually confirming a signal change remaining time.

In the traffic light interlock control device according to the present invention, the traffic light standby time display device is installed at the intersection or crosswalk to communicate the vehicle and people in accordance with the lighting of the traffic light (4); An LED display unit 6 which sets differently for each color to be turned on in the traffic light 4 and then displays waiting time for signal conversion; And a signal light controller 2 for controlling the lighting of each color of the signal lamp 4 and controlling the display of the standby time remaining on the LED display unit 6; and the lighting time set in the setting unit 20. After performing the first step of setting to be operable according to the order and period and performing the second step of lighting control of the traffic light 4 according to the set order and confirming the currently lit color to the set time according to the checked color. After the counting operation is completed and the counting operation of the set time is completed after the display control is performed, the third step of performing the second step is performed again.

According to the present invention, it is possible to know the traffic light replacement time, so that sufficient preparation for the signal change can be ensured smooth traffic flow and there is an effect that traffic accidents can be prevented.
