Description

  The present invention relates to a construction-use simplified traffic signal controller used for renewal work of a permanent traffic signal controller.

  When renewing the traffic signal controller, the function of the permanent traffic signal controller must be temporarily stopped. Meanwhile, traffic lights are turned off at intersections. During the extinguishment period of the traffic light, police officers and staff are standing at the intersection to organize traffic by hand signals in order to ensure traffic safety. In the event of a failure of the traffic signal controller, there has been an attempt to enable replacement of the control unit without turning off the signal lamp. As such an attempt, in Patent Document 1, a combination signal of lighting / extinguishing light output by the control unit is stored in a time series between the control unit and the lamp opening / closing unit, and a malfunction occurs in the control unit. A control signal storage / reproduction unit capable of sequentially outputting combination signals stored at times is added, and lighting / extinction control of the signal lamp device is performed based on the combination signal output by the control signal storage / reproduction unit or the control unit. A traffic signal controller is described.

  According to this traffic signal controller, when the control unit is normal, the combined signal of lighting and extinguishing is stored in the control signal storage / reproduction unit, so that it is stored in the control signal storage / reproduction unit when a malfunction of the control unit occurs. Since the combined signal is read out and output, it is possible to replace the control unit without extinguishing the signal lamp, and when the unexpected situation occurs in the signal controller and the control unit breaks down, the control unit is Since this function is supplemented, traffic safety at intersections can be ensured.

  However, even with such a traffic signal controller, when the renewal work including the control unit and the lamp opening / closing unit is performed, the function of the traffic signal controller must be temporarily stopped. It is not possible to avoid turning off signal lights. This is because the update work of the traffic signal controller itself cannot be performed unless the function of the traffic signal controller itself is stopped.

In order to prevent the signal lamp from being extinguished even during the renewal construction period of the traffic signal controller, for example, a method of installing an alternative temporary traffic signal can be considered. A typical temporary traffic light is a temporary traffic light for road construction. However, most temporary traffic signals for road construction are for smooth one-sided traffic control and are not designed to fit the specific signal floor at the intersection. Traffic lights cannot be installed at intersections such as 3-way and 4-way.
