Description

  The present invention relates to a pedestrian signal lamp, and more specifically, displays a time display that facilitates grasping of a walk prohibition time (wait time) and a walkable time (remaining time) together with a display signal. The present invention relates to a pedestrian signal lamp.

Current traffic signal lamps include red, yellow, and blue (blue arrow) signal lights for vehicles, and red and blue (blue blinking) signal lights for pedestrians. . The lighting timing of these display signal lamps is controlled by a signal controller based on a time table called a display floor table. In order to improve visibility from vehicles with high speed, the display signal lamp for vehicles does not display very detailed instructions, but the display signal lamp for pedestrians is a distance from the pedestrian. In recent years, there are signal lamps that clearly display the barred walking time with a red light and the walking time with a green light in a bar graph. This is provided for the purpose of reducing the psychological stress of pedestrians caused by the fact that the walking prohibition time and the remaining walking time are not clear, and to improve safety. In addition, the display signal lamp for vehicles and the display signal lamp for pedestrians are not lit independently of each other, but are always linked to the operation of the display signal lamps for vehicles. By controlling lighting of the current signal lamp, it is possible to prevent a situation in which an intersecting vehicle and a pedestrian pass the intersection at the same time by a green signal.
However, the lighting timing of the vehicle indicating signal lamp is not always constant, and the lighting time is changed according to the traffic volume and the time zone. For example, it is possible to detect the number of vehicles passing through an intersection with a vehicle sensor and adjust the time of red light and green light according to the traffic volume, or lengthen the time of the green light in the time zone when the traffic volume is low at night. Has been done. Along with that, the timing of the pedestrian display signal lamp is also slightly changed. However, the bar graph display of the pedestrian prohibition time with the red signal and the walkable time with the blue signal is the same as that of the display signal lamp for the vehicle. Since the display time is not corrected even if the timing changes, the pedestrian cannot be notified of a clear time by suddenly turning off at the end of lighting or lighting longer than necessary.
In Patent Document 1, as a signal light device for pedestrians that informs the conventional walking prohibition time and walkable time, a change in the walking prohibition time is displayed on the walking prohibition time display unit corresponding to the lighting of the red indication lamp, In the pedestrian waiting time display device that displays the walkable time on the walk permission time display unit corresponding to the lighting of the blue display lamp, the walking prohibition time display unit is driven to start driving by the lighting of the red display lamp. A technique is disclosed in which the walking permission time display unit is driven by a power source and is driven by a driving power source that starts driving when the blue indicator lamp is turned on.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely illustrative examples and not intended to limit the scope of the present invention only unless otherwise specified. .
FIG. 1 is an internal block diagram of a pedestrian signal lamp according to the present invention. This pedestrian signal lamp 100 includes a serial signal (SIO), a common signal (COM), a signal of a red indicator lamp (PR) of a pedestrian signal lamp, and a pedestrian from a traffic signal controller 1 (not shown). The signal of the blue indicator lamp (PG) of the traffic signal lamp and the signal of the yellow indicator lamp (Y) of the vehicle signal lamp are inputted, and the common signal (COM) and the red indicator lamp of the pedestrian signal lamp ( The signal PR) lights the walking prohibition display board 6, and the common signal (COM) and the signal of the blue indicator lamp (PG) of the pedestrian signal lamp light the walking permission display board 8. In the conventional pedestrian signal lamp, the elapsed time display units 4, 5, 7, and 9 are lit by the display control unit 3 based on the above signals. In the present invention, a serial signal (SIO) or a signal of a yellow indicator lamp (Y) of a vehicle signal lamp is input in addition thereto so that the time of the elapsed time display sections 4, 5, 7, and 9 can be accurately turned on. (Details will be described later). In FIG. 1, both the serial signal (SIO) and the signal of the yellow indicator lamp (Y) of the vehicle signal lamp are input from the traffic signal controller 1, but either one may be input. . Moreover, although the example which inputs a yellow indicator lamp (Y) was demonstrated, it is not restricted to this, A blue indicator lamp (G) may be sufficient.

FIG. 2 is a diagram showing an example of the presently displayed floor table. Here, 1P and 2P are signal lights for crossing pedestrians, 1 and 2 are signal lights for crossing vehicles, a thick black line is a blue indicator lamp (hereinafter referred to as a green signal), and a vertical line is The blinking blue signal, the wavy line represents the yellow indicator lamp (hereinafter referred to as the yellow signal), and the double line represents the red indicator lamp (hereinafter referred to as the red signal). In Fig.2 (a), a horizontal axis | shaft represents a timing period and a vertical axis | shaft represents each signal lamp. For example, at the timing 1, the signal lamps 1P and 1 in the same direction are green signals, and the signal lamps 2P and 2 that intersect are red signals. Next, at timing 2, the green light of the signal lamp 1P in the same direction blinks, the signal lamp 1 is a green signal, and the signal lamps 2P and 2 that still cross each other are red signals. Next, at timing 3, the signal lamp 1P becomes a red signal and the crossing of the pedestrian is stopped, but the signal lamp 1 is a green signal. At timing 4, the signal lamp 1P changes to a red signal and the signal lamp 1 changes to a yellow signal. At timing 5, all the signal lamps turn red simultaneously. This empties the intersection. At timing 6, the signal lamps 2P and 2 in the same direction are turned into a blue signal and the intersecting signal lamps 1P and 1 are turned into a red signal, and the same operation as described above is repeated. Here, the signal lamp device 1 and the signal lamp device 2P, and the signal lamp device 2 and the signal lamp device 1P are signals at positions that intersect each other. For example, when considering the case of the signal lamp 1 and the signal lamp 2P, if the timing is fixedly unchanged as shown in FIG. 2A, the signal lamp 2P will be at timings 8-5 regardless of the timing 4 of the signal lamp 1. Until then, the red signal is changed to a green signal at timing 6 and then repeated at the timing shown in the figure. However, in reality, the signal lamp 1 is turned on with a slight change in timing (often increasing or decreasing the green signal) due to changes in the time zone or traffic volume.
