JPH0741699U - Traffic lights for road construction - Google Patents

Abstract

(57) [Summary] [Purpose] During road construction, the traffic control signal is controlled by a sensor that recognizes the presence or absence of a waiting vehicle, and the purpose is to prevent traffic congestion during road construction. .. [Structure] The main body (1), the sensor (2), the control box (3), and the support (4) are constructed so that they can be easily installed on the side of the road under construction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is intended to prevent traffic congestion with a traffic light for traffic control during road construction, which has a sensor for recognizing the presence or absence of a vehicle waiting.

[0002]

[Prior art]

 Conventional traffic lights for road construction are switched only by a timer.

[0003]

[Problems to be solved by the device]

 Road works often require one-way traffic, so road work signals are installed. Since the switching is done by a timer, it has nothing to do with the traffic of cars. Therefore, traffic congestion is involved during road construction.

Depending on the time of day, the direction of travel is often biased to one direction, and those who do not have a waiting vehicle are blue for the same time. Therefore, the driver is irritated.

When there is a lot of traffic congestion, a switching operator carries out switching by watching the situation.

[0006]

[Means for Solving the Problems]

 In the present invention, a sensor for recognizing the presence / absence of a vehicle waiting is connected to a traffic signal for road construction.

[0007]

[Action]

 When the timer switches to a green light, the sensor recognizes the presence or absence of a waiting car and remains red when there is none. When the car approaches, it returns to the conventional function and switches to blue after the set time.

[0008]

【Example】

 Examples will be described with reference to the drawings. In the figure, it is a road traffic signal equipped with a sensor which is mounted on a conventional traffic signal and recognizes the presence or absence of a waiting vehicle. This is screwed and can be installed at a conventional traffic light or at a position different from the traffic light.

[0009]

[Effect of device]

 The present invention eliminates the deviation of traffic volume in one direction only during the time zone, and the other side does not stop in red even if there is no waiting vehicle.

Traffic congestion is alleviated.

The obstacle to the construction is reduced.

The frustration of the driver is reduced.
