Description

If you are running toward an intersection with a traffic light and the yellow traffic light is lit, the car applied the normal brakes and placed a free running distance + braking distance = stop distance from the stop position required at the intersection. A high-performance camera is equipped with a technology that draws a line on the road in yellow at the final point where the car should normally be braked, and a speed control device at the intersection with a traffic light. The present invention relates to a technique for taking a photograph of a car or the like passing through a stop position required at the intersection when it is lit in red at a speed that cannot be stopped in the vicinity.

In the prior art, an intersection with a traffic signal was dangerous even if it was not in a particularly dangerous place. The reason is that a traffic light legal action can become illegal in seconds by flashing a traffic light.
According to the sixth revised edition P11 on June 1, 2002, the traffic rules-for drivers-(Supervisory and Metropolitan Police Department Transportation Bureau)
"Significance-Yellow light-Cars and streetcars should not move forward from the stop position. However, if the yellow light is approached, it is approaching the stop position and cannot be stopped safely. Can continue. "
However, whether or not it can be stopped safely is a matter of sensation, and when the color of the traffic light changes at each intersection, there is a problem that it can always be judged suddenly.
Also, in the investigation after the accident, the problem of what color the traffic light was at that time is an important issue in many cases even if the brakes and tire marks are known.

When driving a car and approaching an intersection, if the traffic light turns yellow, it is no longer necessary to brake at this point, and it is no longer in time, so it is appropriate to pay attention to the front, back, left and right The first drawback is that there is no way to inform the driver in such a way that there is no effect when it is usually signaled with a green light.
Then, after the accident, a clear one that shows what color the traffic light at that time was,
For example, the second drawback is that there is no photo.
The present invention has been made to solve these two drawbacks.

If you are driving to the intersection with the traffic light (1) at the speed limit of the road and the traffic light is lit yellow, the car will apply the normal brakes and perform well on a normal dry road surface. In the case of wearing tires, the color may be anything at the final point where the car should apply normal braking, with the free running distance + braking distance = stopping distance from the stop position required at the intersection. Final brake point instruction line (2) that draws a line on the road in yellow

If you are driving to the intersection with the traffic light (1) at the speed limit of the road and the traffic light is lit yellow, the car will apply the normal brakes and perform well on a normal dry road surface. In the two cases, when wearing tires and when the road surface is wet with rain and the tires are worn within the range permitted by law, the distance traveled from the stop position required at the intersection is reversed. + Braking distance = Stop distance, the car should be braked normally, and the last brake point indication line (2) that draws two lines on the road in any color at each final point .

The width of the width of the final brake point indicating line (2) should be the thickness of the width determined in relation to the Road Traffic Law, or the difference in brake performance from time to time can be used as it is. The width of the point indicating line (2) is the thickness of the line.

A final brake point indicating line (2) in which one of the two final brake point indicating lines (2) obtained previously is made a dotted line, a color is changed, or both are drawn.

Also, the two final brake point instruction lines (2) may be combined into one, one thick line, and eventually a rectangular section,
2. The inside of the rectangle is hatched from either the left or right side.
3. Make sure there are one or more x marks inside the rectangle with diagonal lines from the left and right.
4. Make the instruction line thicker or thinner (with or without a rectangle indicating the range)
5. Inside the rectangle, B (acronym), BRAKE (English), BREMSE (German),
F (initial letter), FREIN (French), FRENO (Spanish, Italian), etc.
Final brake point indication line (2).

There is no effect on the car running, turning, or stopping normally, and it does not give the driver discomfort.
In order to clearly understand that the driver ran on top of it, we took technology such as step pavement and road bail.
(5) The final brake point instruction line (3).

The final brake point indicating line (2) is wide so that it can be easily seen from the driver's seat so that it can be easily understood that the driver has reached the final brake point indicating line (2).

Pass the final brake point indicating line (2) over the roadside belt from the road so that the driver can easily understand that the final brake point indicating line (2) has been reached. The last brake point indicating line (2) with a pole (4) of about 1 to 5 meters drawn on the sidewalk.

A speed control device (5) is installed at the intersection with the traffic light (1), and the traffic light (1) and the speed control device (5) are linked with one or two high-performance cameras (6, 7). Traffic light (1) provided with a transparent window (8) in part of the red light (11) among the three color lights (of the traffic light) when lit red
Pass through one stop (6) on the top and one (7) where the driver's face is reflected, at a speed that cannot be stopped in the vicinity, for example, 10 kilometers or more, at the intersection. You can take one or two photos of the car you are driving or the car that is entering the intersection (with registration number (12) of course).

Also, if you take two pictures, the date and time (9) of the picture will be taken so that you can see that the two pictures were taken at the same time. The number of seconds elapsed (10) after the traffic light is lit red is also printed in the photo at the same time as the photo.

Finally, in the case of a traffic light (1) that displays a blue arrow (→) that can turn right in a specific direction, especially the blue arrow (→), the timing for displaying the blue arrow (→) is changed from blue to yellow from the timing when the current yellow changes to red. Advance to change timing.
At present, when approaching an intersection with a traffic light (1) that displays a blue arrow (→) that can be turned to the right when it is scheduled to turn right, when the yellow light is seen, the brake is operated to stop if possible. Whether it stops or does not stop, you must start again by looking at the light of the blue arrow (→).
This is slightly different from the brake operation for safely passing through the intersection, and also requires the driver to operate differently than when the traffic light (1) passes at the first green light. Inappropriate and unnecessary.
The present invention is a “final brake point indicating line” configured as described above.

When the traffic light turns yellow, it is no longer necessary to brake at this point, or it is no longer in time. Also, if you ignore the red light, and if you can take a picture exactly, you will naturally ignore the conviction signal, or you will notice that the number of signal ignorance that you have committed is drastically reduced, in a true sense One step closer to traffic safety.
Of course, there is a difference in the performance of the brakes, but as shown in the previous "Training rules for traffic-for drivers" as "Guide for speed and stopping distance"-P36, a certain standard can be shown. If it contributes to road safety, there is no reason to refuse it.

Further, the difference in brake performance from time to time may be the width of the final brake point indicating line (2) as it is.

Embodiments of the present invention will be described below.
When driving a car and approaching an intersection, if the traffic light (1) turns yellow, it is no longer possible to brake at this point, or it ’s no longer in time, so it ’s important to be careful about the front, back, left and right. The proper point can be clearly seen by visual rather than by sensation, for example, by the final brake point indicating line (2) of a yellow line.
Unfortunately, even after the accident, if the traffic light on either side is red, that is, there is always a clear picture that shows what color the traffic light (1) at that time was, that is, a photograph is strictly present.

Here, if it is impossible to install a speed control device (5) at an intersection with a traffic light (1) nationwide, it is of course possible to use only an intersection with a high accident rate or a high number of accidents. When the camera film cost becomes a problem, the traffic light in front of the driver changes from yellow to red, and after a few seconds the left and right traffic lights change from red to blue.
At a corner intersection, all traffic lights at that intersection will change from red, red to red, and blue, but if the total time is not possible, only the second half, that is, the more dangerous before and after the red and blue hours. There is also a way to leave.
