Description

The present invention relates to a dangerous vehicle warning system for preventing a traffic accident, and more particularly to a dangerous vehicle warning system for transmitting the presence of a dangerous vehicle traveling on a road to pedestrians and bicycles.

Conventionally, traffic accidents involving pedestrians have occurred due to ignoring traffic lights near intersections of vehicles traveling on the road or excessive speed at intersections without traffic lights. In addition, traffic accidents are increasing due to the inability to drive due to sudden illness and the increase in the number of elderly drivers due to the aging society and the increase in misrecognition due to driving errors and dementia by elderly drivers. In addition, terrorist acts have also occurred in which vehicles are runaway on sidewalks where pedestrians come and go and pedestrian paradises.

In order to prevent such traffic accidents, an automatic braking system is installed in the car, and when a person is recognized by a human sensor installed in the car, the brake is automatically applied when the driver does not apply the brake. Working systems are beginning to be installed in automobiles. However, in such an automatic braking system, as the speed of the vehicle increases, the distance until the vehicle stops increases, and the overspeeded vehicle may not be stopped before colliding with a pedestrian.

There is also a warning system that alerts the driver to the presence of a pedestrian by means of a voice such as a warning sound or a warning when a person is recognized by a motion sensor installed in the car. It is used. However, if the brakes are not in time due to excessive speed, or if the driver does not recognize or ignore the warning, the brakes may not be operated at all. Moreover, it still takes a long time for these automatic braking systems and warning systems to be installed in all vehicles.

Therefore, more effectively, in order to prevent traffic accidents, pedestrians and other vehicles are notified of the existence of vehicles traveling on the road, and pedestrians recognize the existence of dangerous vehicles to make them dangerous vehicles. A system has been proposed in which pedestrians can protect themselves by avoiding contact with the vehicle.

As such a traffic accident prevention system, information detected after detecting the approaching movement of a vehicle with a detector provided at a desired distance from a display body installed in a dangerous place such as a road near a pedestrian crossing. Is proposed to a display body to display light emission to alert passers-by to vehicles approaching and moving to dangerous places (Patent Document 1).

In addition, a flashing light provided at an intersection and a detection signal for detecting the traveling speed of a vehicle traveling on the road and transmitting a detection signal when the detected speed exceeds a predetermined speed are provided at a predetermined distance from the intersection. A traffic accident prevention device including a vehicle measuring device and a controller that controls blinking of a blinking light in response to a detection signal from the vehicle measuring device has been proposed (Patent Document 2).

In addition, the control unit calculates the possibility of collision between the automobile and the pedestrian from the information on the position, the traveling direction and the speed of the automobile and the pedestrian detected by the detection sensor that detects the position, the traveling direction and the speed of the automobile and the pedestrian. According to the result, a danger notification device has been proposed that controls the operation of the protrusions of a panel having a plurality of protrusions that can move up and down, which are embedded in the road surface (Patent Document 3).

However, in the prior art described in Patent Document 1, although the pedestrian or the bicycle can recognize the existence of the vehicle within a certain distance, the speed and the traveling direction of the vehicle cannot be grasped, and the pedestrian cannot. There was a problem that it was not possible to judge the presence or absence and degree of danger of the vehicle.

Further, in the prior art described in Patent Document 2, since a blinking light for notifying the existence of a vehicle is provided at an intersection and is recognizable from all roads leading to the intersection, the blinking light is installed at the intersection. It had to be installed in the center, and could not be installed on existing traffic lights or utility poles, and flashing lights had to be installed directly on the road or on newly erected poles. If the flashing lights are installed directly on the road or on the columns, it will obstruct the passage of vehicles and may lead to an increase in traffic accidents. If new columns are installed, the flashing lights may increase. It has the disadvantage that the installation work and maintenance work become complicated and the installation cost is high, and it is not practical. Furthermore, since the blinking lights blink in various patterns to indicate the position of the vehicle, the pedestrian cannot grasp the position and the direction of travel of the vehicle, and the pedestrian is in danger of the vehicle. There was a problem that it was not possible to judge the presence or absence and degree of.

Further, in the prior art described in Patent Document 3, a detection sensor that detects the position, traveling direction, and speed of a pedestrian as well as the automobile is required, and a control unit that calculates the possibility of collision between the automobile and the pedestrian. The configuration is complicated and the installation cost is high, which makes it impractical. Further, in a place where there are many pedestrians, it is difficult to detect information on all pedestrians, and it is not easy to notify pedestrians of danger by calculating the possibility of collision between a car and pedestrians. There was also a point. Further, since a panel having a plurality of protrusions that can move up and down is embedded in the road surface, the installation work and maintenance work become complicated, and the installation cost becomes high, which is not practical. It was.

Further, in the prior art described in Patent Documents 1 to 3, a measuring device such as a detection sensor for detecting the movement and speed of an automobile and a warning device such as a display body for notifying pedestrians of danger are predetermined. Since they are installed at a distance, there is a drawback that the installation work and maintenance work become complicated.

Further, in these conventional techniques, in order to give a warning to a pedestrian only based on the speed of the vehicle at a certain point or the information of the traveling direction, the subsequent change in the behavior of the vehicle can be used as a judgment material. It was not possible to grasp the change in danger due to the change in vehicle behavior. Therefore, depending on the behavior of the vehicle after that, the existence of a vehicle that is not dangerous to the pedestrian may warn the pedestrian, or conversely, the existence of the vehicle that is dangerous to the pedestrian cannot be grasped. In addition, there is a problem that the necessary warning may not be given to pedestrians, the danger of the vehicle cannot be correctly judged, and a reliable warning cannot be given.

Further, in these conventional techniques, a change over time in how the vehicle behaves in order to warn a pedestrian based only on the speed of the vehicle at a certain point or further information on the traveling direction. Since the danger is not judged based on the information in, even if the speed is not exceeded, the danger of dangerous driving such as fluttering running or running with repeated acceleration and deceleration is not judged, and the danger of the vehicle is not judged. There was a problem that it was not possible to judge the sex reliably.
