JP2012014664A - Countdown traffic light - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a countdown traffic light to solve the problems that in the conventional traffic lights, each driver is required to instantly judge stop or passage at a traffic light when a green light turns yellow, and the judgment is difficult depending on the type of and the installation place of traffic lights, leading to traffic accidents.SOLUTION: A countdown traffic light can notify a driver of the timing that a traffic light shifts from green to yellow by displaying the left time (the number of seconds) until the green light turns yellow on the green light of an LED traffic light and counting down it.

Description

Technology field

  The present invention relates to a traffic light, and allows a driver to determine in advance the timing at which a green signal changes to a yellow signal by modifying the green signal portion of the traffic signal.

  As a means for the driver to determine that the front signal changes from a green signal to a yellow signal, it can be determined only by the blinking of the green signal of the pedestrian traffic light.

  However, it is not possible to make a judgment in advance for a traffic light that does not have a traffic light for pedestrians or for traffic lights that are difficult to see due to obstacles. It is a major cause of traffic accidents. It is an object to solve such danger.

  In order to solve this problem, the invention of claim 1 assigns a number to each LED of the blue signal of the traffic light using the LED, and the LED that is turned off by turning on and off the LED becomes a black signal as a black number. It is a warning signal that displays the remaining time (seconds). This allows the driver to recognize the remaining number of seconds.

  According to a second aspect of the present invention, the warning signal device is characterized in that a timer is linked to a green signal of a traffic light using an LED to count down the time (seconds) when the green signal changes to a yellow signal. This allows the driver to be informed of the remaining time (seconds) when the green light changes to a yellow light, so that the driver can make a decision with enough time to stop but cross.

  According to the present invention, it is possible to notify the driver of the timing when the green signal changes to a yellow signal, and it is possible to determine whether to stop or cross over with a grace period, so that it is possible to greatly reduce traffic accidents due to droughts and judgment errors.

  In FIG. 1, each LED of the blue signal of the traffic light using the LED has a number, and when the LED is turned on and off, the LED that is turned off displays the remaining time (seconds) on the blue signal as a black numeral. It is a figure of the warning signal characterized by things.

FIG. 2 is a diagram of a warning signal that is characterized by counting down the time (seconds) when the green signal changes to a yellow signal by linking a timer to the green signal of the traffic light using LEDs.
As shown in the figure, for example, if the countdown is made from 9 seconds, which is a single digit, the driver can be given 9 seconds of judgment.

  If the driver's vision is maintained, a method may be used in which the number portion to be displayed on the green light is turned on and the other portions of the green light are turned off and displayed.

  The traffic light of the present invention has the potential to greatly reduce traffic accidents.

  A feature is that each LED of the blue signal of a traffic light that uses an LED is given a number, and when the LED is turned on and off, the LED that is turned off displays the remaining time (seconds) on the blue signal as a black number. It is a figure of the warning signal to perform.   It is a figure of the warning traffic signal characterized by counting down the time (seconds) when a green signal changes into a yellow signal by linking a timer with the green signal of a traffic signal using an LED.

1. Numbers such as X1, X2,... Are assigned in order from the left end of the horizontal axis X, and numbers such as Y1, Y2,. By turning off the LED where the horizontal axis X and vertical axis Y corresponding to the number to be displayed are turned off, the blue signal part that displays the remaining time (seconds) in the blue signal as a black number 2 Normal blue signal lighting 3 The blue signal changes to a yellow signal Display 9 seconds ago 4 Display 8 seconds before the blue signal changes to yellow signal 5 Display 7 seconds before the blue signal changes to yellow signal 6 Display 6 seconds before the blue signal changes to yellow signal 7 5 seconds when the blue signal changes to yellow signal Previous display 8 Display 4 seconds before the blue signal changes to yellow signal 9 Display 3 seconds before the blue signal changes to yellow signal 10 Display 2 seconds before the blue signal changes to yellow signal 11 1 second before the blue signal changes to yellow signal Display 12 Light on yellow signal 13 Light on red signal

Claims (2)

  A feature is that each LED of the blue signal of a traffic light that uses an LED is given a number, and when the LED is turned on and off, the LED that is turned off displays the remaining time (seconds) on the blue signal as a black number. Warning signal   A warning signal that counts down the time (seconds) when the green signal changes to a yellow signal by linking a timer to the green signal of a traffic signal that uses LEDs.
