Abstract

PURPOSE:To decrease traffic accident occurring between vehicles, or a pedestrian and the vehicle at a crossing by effectively utilizing light given through a road-lighting and the headlight of the vehicle to easily recognize the existance of the vehicle running at a dead angle position and of the pedestrian crossing a pedestrian's crossing. CONSTITUTION:In the case where an automobile A3a runs in the dead angle area of an automobile C3c at a road crossing with the crossing put between them, a photoreceiving section 1a receives the light of the headlight of the automobile A3a, and an emission section 2a emits light at once for informing the driver of the automobile C3c the existance of the automobile A3a. Similarly, as the automobile A3a advances, the emission sections 2a to 2d are turned on in order, and the driver of the automobile C3c can recognize the running speed of the automobile A3a on the existance of the automobile A3a and the change of the speed of the emission sections turned on in order.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic safety device using a vehicle headlight.

[0002]

2. Description of the Related Art Generally, in road traffic, as a method of recognizing automobiles traveling in mutually blind spots, recognition by sounds and horns emitted when the automobiles travel, in addition to this, at night, automobile lights, etc. There is recognition by light.

Particularly, at a nighttime intersection, an automobile or a two-wheeled vehicle traveling opposite to the blind spot of an automobile driver trying to make a right turn cannot be visually recognized by the automobile driver. When I made a right turn, I checked that there were no two-wheeled vehicles or automobiles and checked the changes in the road surface brightness due to the lighting of the automobile, and then made a right turn. In addition, after checking the pedestrians crossing in front of the car driver who is trying to make a right turn, he was making a right turn.

[0004]

As described above, in the conventional intersection driving, even a vehicle traveling in the blind spot of a vehicle driver who is going to turn right or a pedestrian crossing a front pedestrian crossing can drive the vehicle. Much depends on skill and attention. Therefore, it is not enough for traffic safety.

It is an object of the present invention to provide a traffic safety device which can improve the safety when the vehicle turns right by effectively utilizing the headlight of the vehicle. Further, the present invention effectively utilizes the light of road lighting and vehicle headlights to make it easier to recognize the presence of a vehicle traveling at a blind spot or a pedestrian crossing a pedestrian crossing, and It is an object of the present invention to provide a traffic safety device that reduces traffic accidents between one another and pedestrians and vehicles.

[0006]

In order to achieve the above object, the traffic safety device of the present invention has the following configuration.

That is, the presence of the vehicle A is notified to the driver of another vehicle B by using the light receiving section for receiving the light from the headlight of the vehicle A traveling on the road and the light received by the light receiving section. The light emitting unit for notifying and the connecting unit for connecting the light emitting unit and the light emitting unit with an optical fiber are provided, and the light from the headlight of the vehicle A is transmitted to a position where the driver of the vehicle B can see.

Further, a plurality of the light receiving portions, the light emitting portions, and the connecting portions are installed, and the light receiving portions and the light emitting portions are arranged at equal intervals in the road axis direction so that the light receiving portion receives light from the headlight of the vehicle A. The light is sequentially received, and the light is sequentially emitted from the light emitting unit.

Further, a part of the light is taken out from the lamp in the road lighting equipment by using an optical fiber and is used as a light source of the light emitting portion. Furthermore, a detection unit corresponding to the light emitting unit is installed in the central divider, and a vehicle passes between the light emitting unit and the detection unit to detect the presence or absence of the vehicle by blocking light, walking across a pedestrian crossing A detector is installed at a position where people can be detected, and it detects pedestrians crossing a pedestrian crossing.

[0010]

By using the light receiving section for receiving the light from the headlight of the vehicle A traveling on the road and the light received by the light receiving section, the presence of the vehicle A is notified to the driver of the other vehicle B. The light emitting unit for notifying, and the connection unit for connecting the light receiving unit and the light emitting unit with an optical fiber transmits the light from the headlight of the vehicle A to a position where the driver of the vehicle B can see the light emitting unit. By making it emit light, that is, by using the light of the headlight of the vehicle, it is possible to inform the driver of another vehicle about to make a right turn of the existence of the vehicle traveling at the blind spot at the intersection at night.

In the case where a plurality of light receiving portions, light emitting portions, and connecting portions are installed and the light receiving portions and the light emitting portions are arranged at equal intervals in the road axis direction, the light receiving portion sequentially receives light from the headlight of the vehicle A. Then, the light is sequentially emitted from the light emitting unit, and it is possible to inform the behavior of the vehicle traveling at the blind spot position to another vehicle driver who is about to make a right turn at the intersection at night.

Further, in the case where a part of the light is taken out from the lamp in the road lighting equipment by using the optical fiber, it is possible to effectively use the light from the road lighting by using the taken out light as a light source of the light projecting section. Becomes

In the case where the detection section side is installed in the median strip so as to correspond to the light projecting section, the vehicle passes between the light projecting section and the detecting section and detects the presence or absence of the vehicle by blocking the light. It will be. If the light receiving unit is installed at a position where a pedestrian crossing a pedestrian crossing can be recognized, a pedestrian crossing the pedestrian crossing will be detected.

Further, a detector for detecting a pedestrian crossing,
A light emitting unit that emits light by this detection notifies a vehicle about to make a right turn to the presence of a pedestrian crossing a pedestrian crossing in front of it by detecting a pedestrian.
