Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for informing a driver of a point desirable for applying a brake and a point appropriate to run through paying attention to all directions when a signal turns to yellow at an intersection, and a method for knowing, after an accident, what color the traffic signal has turned into at that time. <P>SOLUTION: When a yellow color of the signal 1 is lighted while traveling at a limit speed of a road toward the intersection with the signal 1, a line is drawn in yellow on the road, at a final point at which the usual brake must be applied with a stopping distance = an idle running distance + a braking distance, and the intersection is provided with a speed control device side by side, and the signal 1 and the speed control device are interlocked to take a photograph of a vehicle or the like passing through at a speed impossible to stop in its vicinity, e.g., at 10 km/h or higher, on a stop position required in the intersection by one or two high performance cameras from one machine on the signal 1 and from another machine in a place where the driver's face can be photographed when a red color is lighted. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

If you are running towards an intersection with traffic lights and the yellow lights on the traffic lights, the car applied the normal brakes and set the free running distance + braking distance = stopping 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 brake, 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. "
Although it is written, whether it can stop safely is a problem of sensation, and there is a problem whether it can be done suddenly at each intersection.
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, the second drawback is that there is a clear one that shows what color the traffic light at that time was, for example, 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 turns yellow, the car will be able to exert its performance on a normal dry road surface with normal braking applied. 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. The last brake point 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 tires are worn out on a wet road surface, the free running distance + braking distance = stop distance is set in reverse from the stop position required at the intersection. Also, the brake point final line (2), which draws two lines on the road in yellow, although the color can be anything at each final point where the car should apply normal brakes.

The brake point final line (2) in which one of the two brake point final lines (2) obtained in claim 2 is a dotted line, a color is changed, or both are applied to draw a line.

There is no effect on the car running, turning and stopping normally, and the driver will not feel uncomfortable, but technology such as step pavement and road fly will be used to clearly understand that the driver has ran on it. The last brake point line (3).

The brake point final 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 line (2).

In order to make it easier for the driver to understand that the brake point final line (2) has been reached, the brake point final line (2) crosses the roadside belt from the road so that it can be easily seen from the driver's seat. Brake point last line (2) with a pole (4) of about 1 to 5 meters.

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). When the red light is on, one of the three lights (of the traffic light), one on the traffic light (1) provided with a transparent window (8) in part of the red light (11), From one of the places where the person's face is reflected (7) on the stop position required at the intersection, such as a car passing at a speed that cannot be stopped in the vicinity, for example, 10 km or more, or entering the interior of the intersection Make sure that you can take one or two photos of your car, etc. (with a 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.
The present invention is a “brake point final 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.

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 correct point can be clearly seen by visual rather than by sensation, for example, at the brake line final line (2) of the 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 entire time is not possible, only the second half, ie, the more dangerous red and blue hours, are left in the photo There is also a method.
