DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic perspective view of an intersection where a transportation system according to an embodiment of the present invention is installed. At the intersection shown in the figure, roads 2 and 4 intersect in the east-west direction and north-south direction. Traffic lights 6 to 12 are installed at four points at this intersection. The indication of each of the traffic lights 6 to 12 is an intersection where there is an indication of all red in the first and second indications as shown in FIG. Among the vehicles 14, 16 traveling in the east direction on the road 2 in the east-west direction, the forward vehicle 14 is a straight-ahead vehicle and the following vehicle 16 is a left-turn vehicle. The vehicle 18 from the east direction on the road 2 is a right-turn vehicle. A pedestrian 22 is crossing the pedestrian crossing 20 where the right-turning vehicle 18 enters. Each traffic light 6 installed at such an intersection
Pedestrian detection devices 24 to 30 are installed at 12.
For convenience, the pedestrian detection device 24 installed at the traffic light 6 of the pedestrian crossing 20 into which the right-turn vehicle 18 enters will be described with reference to FIG.
Is composed of a well-known pyroelectric area sensor provided below the traffic light 6 on the pillar 26 installed on the road shoulder, and detects the heat rays emitted from the pedestrian 22 to detect the crosswalk 2
It is designed to detect pedestrians 22 crossing 0,
By this detection, a pedestrian detection signal is output. The pedestrian detection device 24 also has a traffic light controller 29.
The operation timing is controlled by. The same applies to the other pedestrian detection devices 26 to 30.

The traffic light controller 29 will be described with reference to FIG. 4. The traffic light controller 29 shows the operation of the traffic lights 6 to 12 at the intersection and the traffic lights 6 to 12 respectively.
The operation of the pedestrian detection devices 24 to 30 at the bottom of each,
The operations of the display panels 32 to 38, which will be described later, are centrally controlled. Needless to say, this centralized control is an example, and various control methods other than this are conceivable.

Display panels 32 to 38 are provided on the columns for installing the respective traffic lights. Of the display panels 32 to 38 in each traffic light installation pillar, the pillar 26 of the traffic light 6
The display panel 32 installed in FIG. 5 will be described with reference to FIG. 5. The display panel 32 is configured to display the character “crossing” indicating that a pedestrian is crossing and turn right. The vehicle display panel section 32a and the left-turn or straight-ahead vehicle display panel section 32b are attached to the traffic signal installation column 26 in such a manner that the angles can be changed with respect to each other so that the driver's seat of each vehicle can be confirmed.

The operation will be described with reference to the flow chart of FIG. 6. At step n1, the traffic light controller 29 causes the traffic lights 6 and 10 on the north-south direction side to appear in red. in this case,
The east-west traffic lights 8 and 12 are shown in blue. As a result, the pedestrian 22 can cross the pedestrian crossing 20 while the right of passage is given to the vehicles 14, 16 and 18 in the east-west direction. In the following steps, the traffic light 6 and the corresponding pedestrian detection device 24 will be described. Then, the traffic signal controller 29 drives the pedestrian detection device 24 in step n2 at the same time as the red indication control of the traffic signals 6 and 10. The pedestrian detection device 24 performs a pedestrian detection operation by this drive. If there are no pedestrians on the pedestrian crossing 20, the process proceeds to step n4, but in FIG.
Since there is a pedestrian 22 on the pedestrian crossing 20, the pedestrian detection device 24 detects this and outputs a pedestrian detection signal, and proceeds to step n5. Then, in step n5,
In response to the pedestrian detection signal, the traffic signal controller 29 causes both display panel portions 32a and 32b of the display panel 32 to display the character "Crossing" as shown in FIG. As a result, the right-turn vehicle 18 can confirm that the pedestrian 22 is crossing the pedestrian crossing 20 by the display on the display panel unit 32a, and the straight-ahead vehicle 14 and the left-turn vehicle 16 have the display panel unit. Crosswalk 2 according to the display of 32b
It is possible to confirm that the pedestrian 22 is crossing 0. Therefore, when the right-turn vehicle 18 is waiting for the pedestrian 22 to cross and waiting in front of the pedestrian crossing 20, both the driver of the straight-ahead vehicle 14 and the driver of the left-turn vehicle 16 can confirm the waiting state. Then, at step n6, the traffic lights 6, 10
Is displayed in blue, that is, the display on the display panel 32 is continued until the traffic lights 8 and 12 are displayed in red and the crossing is prohibited, and when the crossing is prohibited, the process proceeds to step n7. In step n7, the traffic light controller 29 stops the display on the display panel 32, and in step n8, stops the driving of the pedestrian detection device 24.

In this way, the driver of the vehicle 18 turning right at the pedestrian crossing 20 confirms that the pedestrian 22 is crossing the pedestrian crossing 20 from the indication "crossing" on the display panel. Therefore, safe driving can be performed.

[0015]

As is clear from the above description,
According to the present invention, when the pedestrian detection device detects that a pedestrian is crossing a pedestrian crossing, the pedestrian detection device can display that fact on the display panel, so that a vehicle entering the pedestrian crossing can be displayed. The driver can easily confirm that a pedestrian is crossing the pedestrian crossing and can drive safely. In addition, the driver of the vehicle turning right at the pedestrian crossing at the intersection can easily recognize the pedestrian crossing the pedestrian crossing, and thus can drive safely.
