Then, the information display device 40 informs the driver that
Information in the case of a red light such as “waiting time” (for example, “Please wait about 5 minutes until the signal turns green.”) Is displayed on the LED unit 41. As the waiting time, the remaining time excluding the elapsed time from the time set in the operation time setting unit is displayed (see FIG. 3A). When the time set in the operation time setting unit elapses, the traffic signal 1
Shifts to a green light.

When the traffic signal 1 is a green light, that is, when the function unit 2 indicates that the traffic is permitted, the operation control signal indicating the green signal is transmitted from the control unit 20 to the two-position signal 50, the circuit breaker 60, and the arrow-shaped LED display unit. 71. Then, the two-position signal 50 turns on the blue light and the circuit breaker 60
Lowers the blocking rod 61 and stores the sign board 62 in the sign storage box 70. The arrow-shaped LED display unit 71 emits a green LED to instruct the driver to permit passage. Further, at this time, a display control signal in the case of a green light is output from the control unit 20 to the information display device 40.

Then, the information display unit 40 displays information in the case of a green light (for example, “Under construction. Please pass it carefully.
(B)). Then, when the time set in the operation time setting unit elapses, the traffic light 1 shifts to the red light again, and thereafter, similarly, the green signal and the red signal are alternately displayed.

Next, a case where the operation changeover switch is set to "manual" will be described. When the operation changeover switch is set to "manual", an operator manually switches the traffic light 1 to a red light or a green light. The switching between the red signal and the blue signal is performed by the operator directly operating the function unit 2 or remotely operating the wireless transmitter 3.

When the traffic light 1 is switched to a red light by an operator, an operation control signal indicating a red signal is output from the control unit 20 as in the case where the operation changeover switch is "automatic". The two-position traffic light 50 turns on a red light, and the breaker 60 raises the blocking rod 61 and the sign plate 62 to block the path of the passing vehicle. At this time, a display control signal in the case of a red light is output from the control unit 20, and the information display device 40 outputs information (for example,
"Please wait until the signal turns green.") Is displayed.

Next, when the traffic light 1 is switched to a green light by an operator, the operation changeover switch is set to "automatic".
As in the case of the above, the operation control signal indicating the green signal is output from the control unit 20, the two-position type traffic light 50 turns on the blue light, the breaker 60 lowers the blocking rod 61,
While storing the sign board 62 in the sign storage box 70,
The arrow-shaped LED display unit 71 emits a green LED. At this time, a display control signal in the case of a green light is output from the control unit 20, and the information display device 40 displays information in the case of a green light (for example, "Under construction. I ’ll call you. ”).

The traffic signal 1 repeats the above operation every time the operator switches between the red light and the green light, and indicates a stop instruction or a traffic permission, respectively.

As described above, the traffic signal 1 in the present embodiment uses the information display 40, the two-position signal 50, and the arrow-shaped LED display unit 71 to display information such as traffic regulation contents and waiting time and signal display. Can be confirmed at the same time.

Therefore, the driver confirms the traffic signal 1 and obtains a signal indicating a traffic permission and a stop instruction,
It is easy to grasp the information on traffic regulation, and the time to diverge the line of sight from the front is shorter than when checking the sign and the signboard indicating the information on traffic regulation separately, so that safer driving is possible. Become.

Further, in the case of a red light and a green light, when the blocking rod 61 of the circuit breaker 60 and the sign board 62 are lowered or raised, the instruction to proceed or stop is transmitted to the driver without fail. Safety is improved.

Further, in the case of a green light, the arrow-shaped LED display unit 71 emits light, so that a large arrow is displayed and the driver is permitted to pass.
It can be easily grasped that it is a green light.

Since the traffic signal 1 can be operated from a remote place by the wireless transmitter 3, the operator can operate without having to move to the place where the traffic signal 1 is installed. Therefore, the work efficiency can be improved.

The information display device 40 can display the traffic regulation contents by inputting or selecting the display contents with the operation unit 30, so that there is no need to write the information on a signboard or the like by hand, thereby improving work efficiency. Can be achieved.

Further, the information display 40 is a traffic signal 1
When the traffic light 1 is not in use, it can be folded down and stored as necessary, so that the traffic signal 1 can be easily transported and stored.

In this embodiment, the sign board 62
In the above description, a stop instruction sign is attached, but a sign or the like for displaying other information (for example, a flag indicating "stop", another regulation sign, or the like) may be attached.

In the automatic operation, the switching between the red signal and the green signal is described as being performed in accordance with one time set by the operation time setting unit. However, when the traffic volume from one side of the construction section is large, the red signal is switched to the red signal. The traffic light and the green traffic light may be set to have different times so that traffic from one side of the construction section is not congested.

[0064]
