(Embodiment 1)
A violation preventing apparatus according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 4B.
<1, Configuration of violation deterrence system 1>
The violation deterrent system 1 according to the present embodiment projects an image P1 and the like (see FIG. 2 and the like) near the road using the switching information of the traffic lights 40 for pedestrians installed at intersections and straight roads. Occurrence of traffic violations ignoring red light by pedestrian A1 and driver A2 of bicycle B is suppressed.
That is, the violation deterrent system 1 according to the present embodiment obtains switching information of the pedestrian traffic light 40 (see FIG. 2 and the like) and projects a predetermined image on the road, thereby allowing a pedestrian or the like on the sidewalk to It is installed to remind you to cross the road ignoring the red light.

Therefore, for example, the violation suppression system 1 is installed near an intersection or a specific road where the number of traffic violations ignoring red traffic lights is large.
Specifically, as shown in FIG. 1, the violation suppression system 1 of the present embodiment includes a violation suppression device 10, an image projection device 20, a human sensor (person detection unit) 21, and a signal control device 30. It is equipped with.

(Violation deterrence device 10)
The violation deterrent device 10 of the present embodiment uses the switching information of the traffic light 40 for pedestrians received from the signal control device 30 and crosses the road while ignoring the red signal in the time zone of the red signal 40a, for example. An image that causes the violator to hesitate to cross is projected directly from the image projection device 20 onto the road.
The detailed configuration of the violation inhibiting device 10 will be described in detail later.
Further, in this embodiment, as shown in FIGS. 2 and 3 and the like, a description will be given using a pedestrian traffic light 40 in which a red signal 40a is displayed in the upper stage and a blue signal 40b is displayed in the lower stage.

(Image Projector 20)
The image projection device 20 is a projector for projecting an image onto a road surface or a space near the road. And the image projector 20 is attached to the lower part of the traffic light 40 for pedestrians, as shown in FIG.2 and FIG.3.

The image projection device 20 projects a predetermined image P1 from above in the vicinity of the boundary portion between the roadway R1 and the sidewalk R2 constituting the road.
More specifically, the image projection device 20 acquires control information (switching information) related to switching between the red signal 40a and the blue signal 40b of the traffic light 40 from the signal control device 30 that controls the traffic light 40 for pedestrians. Controlled by the projection controller 12.

For example, when the image projection control unit 12 receives the switching information indicating that the traffic light 40 is the red signal 40a from the signal control device 30, the image projection device 20 receives the switching information of the pedestrian crossing Z as shown in FIGS. An image P1 including character information “STOP” is projected near the entrance.
Here, the image P <b> 1 including the character information “STOP” is projected onto the road until the switching information indicating that the traffic light 40 has been switched to the green signal 40 b is received from the signal control device 30. Further, the image P1 including the character information “STOP” is displayed at the boundary portion between the roadway R1 and the sidewalk R2 on the road.

That is, in the violation deterrent system 1 of the present embodiment, the image projector 20 displays an image P1 or the like having a deterrent effect on the road while the pedestrian traffic light 40 is in the red signal 40a. Project.
As a result, when the pedestrian A1 or the driver of the bicycle B tries to cross the road ignoring the red signal 40a, the image P1 including the character information “STOP” projected in front of the eyes is displayed on the eyes. To enter, it can be reminiscent of crossing the road.
As a result, it is possible to suppress traffic violations of ignoring red light by the pedestrian A1 or the driver A2 of the bicycle B.

(Human sensor 21)
The human sensor 21 is installed in the upper part of the traffic light 40 for pedestrians, as shown in FIG. 2 and FIG. The human sensor 21 constantly detects whether or not there is a person around the traffic signal 40 (particularly on the sidewalk R2).

When the human sensor 21 detects that there is a person around the traffic light 40 (for example, on the sidewalk R2), the human sensor 21 transmits the detection result to the image projection control unit 12, as shown in FIG.
The image projection control unit 12 that has received the detection result controls the image projection device 20 so as to project the violation suppression image P1 only when the human sensor 21 detects that there is a person around.

That is, in the violation suppression system 1 of the present embodiment, the image projection control unit 12 does not depend on the color of the traffic light 40 received from the signal information acquisition unit 11 during a period in which the human sensor 21 cannot detect that there is a person around. Then, the image projector 20 is controlled so as not to project the image P1.
Thus, in the violation suppression system 1 of the present embodiment, the violation suppression image P1 is displayed on the road only when the traffic light 40 for the pedestrian is a red signal 40a and a person is detected around the traffic signal 40. Can be projected upwards.
As a result, when there is no person who is likely to be a traffic violator who ignores red traffic lights, it is effective to avoid the image P1 and the like from being projected from the image projection device 20 and to effectively project the violation. It is possible to switch the presence / absence of projection of the image P1 for violation suppression.

(Signal control device 30)
As shown in FIG. 1, the signal control device 30 is connected to a pedestrian traffic light 40 and performs switching control of the traffic light 40.
Further, the signal control device 30 transmits the switching information of the pedestrian traffic light 40 to the signal information acquisition unit 11 of the violation suppressing device 10.
Thereby, the signal information acquisition part 11 can recognize the color (red signal 40a, blue signal 40b) of the traffic light 40 for pedestrians, and can transmit the information regarding the color of the traffic light 40 to the image projection control part 12.

<2. Detailed configuration of violation deterrent device 10>
As shown in FIG. 1, the violation deterrent device 10 according to the present embodiment provides switching information of the pedestrian traffic light 40 from the signal control device 30, and detection results of people around the traffic light 40 from the human sensor 21. Each is received and the image projector 20 is controlled.

Specifically, the violation deterrent device 10 receives the switching information from the signal control device 30 to the red signal 40a of the traffic light 40 and the detection result of the person around the traffic light 40 from the human sensor 21. In addition, the image projecting device 20 is controlled so as to project the violation inhibiting image P1.
And the violation suppression apparatus 10 is provided with the signal information acquisition part 11, the image projection control part 12, and the memory | storage part 13, as shown in FIG.

The signal information acquisition unit 11 acquires switching information of the pedestrian traffic light 40 from the signal control device 30 described above. Specifically, the signal information acquisition unit 11 acquires switching information indicating that the pedestrian traffic light 40 has been switched to the red signal 40a or the green signal 40b.
Thereby, in the signal information acquisition part 11, when the switching information which shows having been switched to the red signal 40a is received, until it receives the switching information which has been switched to the green signal 40b next, the traffic light It can be recognized that 40 is a red signal 40a. Conversely, when the signal information acquisition unit 11 receives the switching information indicating that the signal has been switched to the green signal 40b, the signal information is acquired until the switching information indicating that the signal has been switched to the red signal 40a next time. It can be recognized that 40 is a green signal 40b.

Therefore, the image projection control unit 12 is in a state in which the pedestrian traffic light 40 displays the red signal 40a and the blue signal 40b based on the switching information received from the signal information acquisition unit 11. I can recognize that. The image projection control unit 12 then projects the image P1 for violation prevention onto the road during the period when the traffic light 40 for pedestrians is detected as the red signal 40a. 20 can be controlled.

That is, when the traffic light 40 for the pedestrian is the green light 40b or when there is no person around the traffic light 40, the image projection control unit 12 suppresses violation on the road as shown in FIG. The image projector 20 is controlled so that the image P1 for use is not projected.
On the other hand, when the traffic light 40 is a red signal 40a and there are people around the traffic light 40, the image projection control unit 12 stores the image information stored in the storage unit 13 as shown in FIG. The image projection device 20 is controlled so that predetermined image information is extracted from the inside and projected onto the road.

The storage unit 13 stores information on the image P1 projected from the image projection device 20 onto the road when the various conditions described above are satisfied. As a result, the image projection control unit 12 takes out information related to the predetermined image P1 from the storage unit 13 based on the information received from the signal information acquisition unit 11 and the human sensor 21, and moves from the image projection device 20 onto the road. Can be projected.

In the violation deterrent device 10 of the present embodiment, as described above, when it is detected that the traffic light 40 for pedestrians is the red signal 40a, the image P1 for violation deterrence is projected onto the road. The projector 20 is controlled.
Thereby, when the signal information acquisition unit 11 receives the switching information indicating that the traffic signal 40 is switched to the red signal 40a, the image projection control unit 12 projects the violation preventing image P1 on the road. The image projection device 20 can be controlled.

Furthermore, in the violation deterrent apparatus 10 of the present embodiment, in addition to the condition that the traffic light 40 is the red signal 40a, the violation deterrence image P1 is satisfied when the condition that there is a person around the traffic signal 40 is satisfied. The image projection device 20 is controlled so that is projected onto the road.
Thereby, it is possible to avoid the violation-preventing image P1 being projected onto the road in the state where there is no person who is likely to be a violator who ignores the red light.

In addition, the projection control of the image P1 for violation suppression using the detection result in the human sensor 21 is not an essential condition for the present invention. That is, the image projection device 20 that projects the violation-preventing image P1 on the road may be controlled using only the traffic light 40 switching information received from the signal control device 30.

(Embodiment 2)
A violation suppression system including the violation suppression apparatus 10 according to another embodiment of the present invention will be described below with reference to FIGS. 5 to 6B.
In the violation deterrent system according to the present embodiment, as shown in FIG. 5, when the pedestrian traffic light 40 is a green signal 40b, an image is displayed on the road from the image projection device 120 attached to the traffic light 140 for an automobile. The point of projection is different from the first embodiment.
That is, in the first embodiment, when the traffic light 40 for pedestrians is a red signal 40a, the image projection device 20 projects an image P1 on the road that makes a person crossing the road of a violator who ignores the red signal appear on the road. Was. On the other hand, in this embodiment, as shown in FIG. 5, when the pedestrian traffic light 40 is a blue signal 40b, the road can be crossed from the image projection device 120 attached to the traffic light 140 for automobiles. The image P2 of the illustration of the pedestrian crossing showing is projected.

As shown in FIG. 5, the image projecting device 120 is attached to the lower surface of the traffic signal 140 for automobiles, and projects an image P2 of a pedestrian crossing from above onto the road surface of the roadway R1.
That is, in the present embodiment, signal control information is acquired from the signal control device 30 in the signal information acquisition unit 11 as in the violation suppression system 1 of the first embodiment. When the pedestrian traffic light 40 is the green signal 40b, the image projection device 120 projects a pedestrian crossing image P2 indicating that crossing is possible on the road surface of the roadway R1.

Here, in the present embodiment, when the pedestrian traffic light 40 is the green light 40b, the image projection device 120 projects the pedestrian crossing image P2, while the pedestrian traffic light 40 is the red traffic light 40a. The image is not projected from the image projection device 120.
That is, in this embodiment, as shown in FIG. 6A, when the pedestrian traffic light 40 is a red signal 40a, a pedestrian crossing for a pedestrian A1 or a driver A2 of a bicycle B to cross the road. However, only a part Z1 of the both ends is displayed.

In addition, the part Z1 of the pedestrian crossing should just be painted on the road like a normal pedestrian crossing.
In the present embodiment, when the pedestrian traffic light 40 is a green light 40b, as shown in FIG. 6B, an image P2 of a pedestrian crossing is projected between a part Z1 at both ends.
As a result, the entire pedestrian crossing for the pedestrian A1 and the driver A2 of the bicycle B to cross the road appears on the road R1. Therefore, when the traffic light 40 for pedestrians is the green light 40b, it can show that crossing is possible with respect to pedestrian A1 grade | etc.,.

On the other hand, when the pedestrian traffic light 40 is a red signal 40a, as shown in FIG. 6 (a), only a part Z1 of the pedestrian crossing appears on the road R1 when viewed from the pedestrian A1 and the like. It can be.
As a result, the pedestrian A1 on the sidewalk R2, the driver A2 of the bicycle B, etc., hesitates to cross the pedestrian crossing where only the part Z1 can be seen, and it is thought that the red light is ignored. . Therefore, by not projecting an image from the image projection device 120, it is possible to effectively suppress the occurrence of traffic violations that ignore red signals.

As a modification of the present embodiment, a part of the pedestrian crossing Z1 painted on the road described above may be replaced with an image projected from the image projection device 120.
That is, when the traffic light 40 for pedestrians is a red signal 40a, only a part thereof is projected onto the road as an image of a pedestrian crossing. And when the traffic light 40 for pedestrians is the green signal 40b, the image which shows the whole pedestrian crossing is projected on a road.

Even in this case, similarly to the above, the pedestrian A1 etc. on the sidewalk R2 can hesitate to cross the road ignoring the red light, and the occurrence of traffic violation can be effectively suppressed.
[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

You may project the image P3, such as a wall etc. which makes the crossing by the pedestrian A1 etc. who are present.
In this way, by projecting the image P3 representing an obstacle such as a wall near the boundary portion that enters the road R1 from the sidewalk R2, traffic violations that ignore red signals by the pedestrian A1 or the driver A2 of the bicycle B, etc. Can be effectively deterred.

Further, as shown in FIGS. 7B and 8, for example, when the pedestrian traffic light 40 is a red signal 40a, the image projection device 220 projects an image of an obstacle such as a wall onto a space near the road. May be used.
As shown in FIG. 8, the image projection device 220 is installed so as to be embedded in the boundary portion of the road that enters the pedestrian crossing Z on the roadway R1 from the sidewalk R2.

In other words, the image projection device 220 is installed so as to be embedded in the boundary portion between the both ends of the pedestrian crossing Z of the road and the sidewalks R2 and R2.
Thereby, it is possible to project an image P3 of an obstacle such as a wall shown in three dimensions from below in the space of the boundary portion between the sidewalk R2 and the roadway R1.
Therefore, it is expected that the pedestrian A1 and the like on the sidewalk R2 side will hesitate to cross further by looking at the image P3 such as a wall that appears in three dimensions. As a result, the traffic violation of ignoring red light by the pedestrian A1 or the driver A2 of the bicycle B can be more effectively suppressed by the three-dimensional image P3 projected on the space on the road.

In addition, as an image projected on the road space from the image projection device 220 embedded in the road, a fence image P4 is used as shown in FIG. 9 instead of the wall image P3 shown in FIG. Also good.
Even in this case, the pedestrian A1 or the like on the side of the sidewalk R2 is expected to hesitate to cross by looking at the image P4 of the fence that appears in three dimensions. As a result, the traffic violation of ignoring the red signal by the pedestrian A1 or the driver A2 of the bicycle B can be more effectively suppressed by the three-dimensional image P4 projected on the space on the road.

In the present embodiment, the image projection device 220 is embedded in the ground and the three-dimensional image P4 is projected from the feet of a pedestrian or the like. However, the installation position of the image projection device is not limited to this. Absent.
For example, an image projection device may be installed on a traffic light or the like, and a three-dimensional stereoscopic image may be projected onto the space from above a pedestrian or the like.

(B)
In the first embodiment, as illustrated in FIG. 2 and the like, the image projecting device 20 that projects the image P1 onto the road has been described as an example provided below the traffic light 40 for pedestrians. However, the present invention is not limited to this.
For example, as shown to Fig.10 (a), you may use the image projector 320a provided in the upper part of the traffic light 40 for pedestrians. Alternatively, as shown in FIG. 10B, an image projection device 320b provided on either the left or right side of the pedestrian traffic light 40 may be used.
Even in this case, the same effect as in the first embodiment can be obtained by projecting the predetermined image P1 and the like onto the road from above.

(C)
In the first embodiment, the switching information of the traffic light 40 for pedestrians is directly acquired from the signal control device 30 that controls the traffic light 40, and an example in which image projection is controlled has been described. However, the present invention is not limited to this.

For example, as shown in FIG. 11, the signal information acquisition unit 11 detects the color of a traffic light using an image photographed by a camera (imaging device) 22 installed in the vicinity of the traffic light 40, and sets traffic signal switching information. The violation suppression device 110 and the violation suppression system 101 may be acquired.
In this case, it is possible to obtain the same effect as in the above embodiment by continuously capturing images with the camera 22 and analyzing the images to obtain the switching information of the traffic light 40 for pedestrians.

(D)
In the first embodiment, as shown in FIGS. 1 and 2, the image projection control unit 12 detects the presence / absence detection result from the human sensor 21 attached near the road where the image projection device 20 is installed. An example of acquiring and controlling the presence or absence of image projection has been described. However, the present invention is not limited to this.
For example, a violation deterrent system that does not have a human detection unit such as a human sensor may be used.
In this case, even when there are no people in the vicinity, an image P1 or the like for suppressing a traffic violation neglecting a red signal is projected onto the road. However, as a deterrent effect, the same effect as in the above embodiment can be obtained.

(E)
In the first embodiment, the human sensor 21 that detects whether or not there is a person around the traffic signal 40 has been described as an example in which the human sensor 21 is attached to the upper portion of the traffic signal 40. However, the present invention is not limited to this.
For example, the human detection unit such as a human sensor does not need to be directly attached to the traffic signal, and may be installed around the traffic signal (for example, a support provided separately from the traffic signal).
In addition, a human detection unit such as a human sensor may be installed so as to be embedded in a road surface of a sidewalk around the traffic light 40.

(F)
In the first embodiment, the example in which a two-dimensional image including the character information “STOP” is projected onto the road as the violation suppression image P1 has been described. However, the present invention is not limited to this.
For example, in addition to the above, an image including other character information such as “prohibition of entry”, “prohibition of crossing”, “prohibition of entry”, and “red signal” may be used as an image for inhibiting violation.
Moreover, you may project these character information as a three-dimensional image.

(G)
In the second embodiment, an example in which a two-dimensional image including an illustration of a pedestrian crossing is projected onto a road has been described as the violation inhibiting image P2 indicating that a crossing is possible at a green light. However, the present invention is not limited to this.
For example, an image including an illustration for deterring violation indicating that crossing is possible at a green light is not limited to an image of a pedestrian crossing, but other illustrations such as an arrow indicating that movement in a crossing direction is possible. An included image may be used.

(H)
In the first and second embodiments, the example in which an image is always projected from the image projection device while the pedestrian traffic light 40 is in the state of the red signal 40a or the blue signal 40b has been described. However, the present invention is not limited to this.
For example, the projected characters and illustrations may be projected so as to blink.

Specifically, when the traffic light 40 for the pedestrian is a red signal 40a, the image P1 including character information such as “STOP” projected near the entrance of the pedestrian crossing Z is blinked, so that the pedestrian or the like Can draw attention.

Since the violation deterring device of the present invention has the effect of effectively suppressing traffic violations by pedestrians and bicycle drivers, for example, for traffic management systems installed on main roads, etc. Widely applicable.
