Description

The present invention relates to a temporary traffic signal that turns on and off a signal according to a predetermined algorithm.

Due to road construction, accidents, etc., the roadway may be restricted to two-way alternate traffic with one lane on each side. At this time, temporary traffic lights are installed at both ends of the two-way alternate traffic section to ensure the safety of vehicle traffic. Patent Document 1 discloses such a temporary traffic signal. When there are no vehicles at either entrance of the two-way alternating traffic section, this temporary traffic signal turns the traffic lights at both entrances red, and when it senses that a vehicle has come to one of the entrances of the two-way alternating traffic section, The signal at one entrance is green and the signal at the other entrance is red. When vehicles arrive at both entrances of a two-way alternate traffic section, both signals are red for a predetermined time, and a predetermined time elapses. After that, both signals are alternately changed to green and red.

According to this temporary traffic signal, the red signal and the green signal are switched according to the presence or absence of a vehicle in a two-way alternate traffic section, so that the control of the traffic signal matches the actual traffic conditions of vehicles. This can reduce vehicle congestion and reduce emissions, noise, time and fuel consumption from congested vehicles.

Also, in the case of construction to replace traffic signals at intersections, etc., temporary traffic signals are installed to ensure the safety of vehicle traffic. As such a temporary traffic signal, there is one disclosed in Patent Document 2. This temporary traffic signal has a plurality of signal lights on the top of a temporary signal pole. The temporary signal is mounted on a vehicle equipped with the temporary signal, and the vehicle equipped with the temporary signal is provided with a signal pole tilting device capable of adjusting an angle so that the axial direction of the temporary signal pole is vertical.

According to the temporary traffic light mounted on the temporary traffic light-equipped vehicle, it is possible to reduce the area occupied on the roadway. That is, when one wheel of a vehicle equipped with a temporary signal is parked on a sidewalk, the installation surface of the vehicle is inclined with respect to the horizontal direction, so the temporary signal pole of the temporary signal is inclined with respect to the vertical direction. However, the axial direction of the temporary signal pole can be adjusted to be vertical by means of the signal pole tilting device. In this way, a portion of the temporary traffic signal-equipped vehicle mounted with this temporary traffic signal can be used while riding on the sidewalk, so that the area occupied by the vehicle on the roadway can be reduced.
