The present invention relates to the pattern of the tunnel inner wall surface for driving safety, and more particularly, the driver's proper tension, driving stability and speed sensing ability are not only excellent, but also a stable horizontal feeling is induced to the driver, thereby significantly improving driving stability. It relates to the pattern of the tunnel inner wall surface which can be made.

In general, a tunnel is formed through a mountain for rapid passage of a vehicle traveling on a highway, and has the advantage of minimizing driving time and driving distance by reducing the traveling distance of the vehicle, but the interior space is dark or air. It is poor in poor driving conditions. Therefore, traffic accidents occur frequently in tunnels.

In detail, when the driver enters the tunnel, various sensory functions are degraded due to sudden change of environment. Among them, the deterioration of visual and auditory function is noticeable. Especially in tunnels, it is difficult to detect the sense of speed and distance due to the distortion of visual sensations while driving. In addition, when entering the tunnel suddenly dark, it takes a long time to adapt the pupil. And looking at the lights inside the tunnel can cause optical illusions, causing psychological factors that cause the driver to look far away.

In addition, when entering the tunnel, the resonance phenomenon causes the ear to be bruised and psychologically excited to speed up. In addition, the driver is speeding due to the psychological characteristics of the driver trying to escape from a closed space such as a tunnel. In addition, the speed of the accident may increase by speeding in the tunnel due to fog generated inside the tunnel due to temperature difference in the tunnel and outside and traffic wind blowing in the narrow tunnel.

Various studies have been conducted to solve these problems and to prevent safety accidents that may occur during operation in tunnels.

For example, Korean Utility Model Publication No. 20-2000-0017885 (published on October 05, 2000) discloses a driver's eye-guided label. However, even if the above invention is applied, the driver is not visually stimulated by the wall of the tunnel when the driver is traveling in the tunnel, so he can hardly feel a sense of speed, and thus it is easy to speed up without the driver himself. In particular, the distance from the vehicle ahead of the car is not easily recognized, there is a problem that frequent collision accidents and contact with the tunnel side in the tunnel.

In addition, the Republic of Korea Utility Model Registration No. 20-0290019 (registered on September 09, 2002) discloses a "tunnel safety display device". In the case of the present invention has the effect of improving the driver's attention and increase the sense of speed, it is cumbersome and not easy to manage because it requires to install a separate facility on the wall, it does not provide the effect of inducing a stable level, balance and tension There is a problem.

Accordingly, an object of the present invention is to improve the speed sensing ability to the driver running inside the tunnel without installing a separate device inside the tunnel, and to provide a safe driving safety that can induce a stable level, balance and tension to the driver. It is to provide a pattern of the inner wall surface for the tunnel.

In order to achieve the object of the present invention described above, according to an embodiment of the present invention is formed in the transverse direction in contact with the first pattern layer and the upper surface of the first pattern layer formed in the transverse direction on the tunnel inner wall surface along the vehicle driving direction And it provides a pattern of the tunnel inner wall surface for driving safety including a second pattern layer of different brightness from the first pattern layer.

A third pattern layer having different brightness from the second pattern may be further formed on the second pattern. Since each pattern layer is in contact with a pattern having a color having a difference in brightness, a so-called mach band is formed. The pattern may be finished, for example, with a tile or the like during tunnel construction, or may be colored using paint.

According to the present invention, since the pattern can be carried out together during the finishing work on the inner wall when constructing the tunnel, it is not necessary to take extra costs or time, and once installed, maintenance costs are not required because no separate management other than washing is required. It is semi-permanent without cost. In other words, it is a very economical way to secure driving safety in tunnels.

And, once the construction as described above, the pattern of the inner wall surface of the tunnel can suppress the rise of the driver's visual fatigue and compensate for the degradation of the speed sensing ability to prevent collisions and safety accidents due to overspeed.

In addition, by forming a modified Mach band pattern having a 'V' or 'sin curve' connected continuously to the inner wall of the tunnel, it gives a visual stimulus to the driver running inside the tunnel can adjust the tension and stability of the driver appropriately . As a result, it is a very economical way to improve the speed sensing capability and driving safety, and consequently to prevent the various safety accidents in the tunnel.

Hereinafter, the pattern of the tunnel inner wall surface for driving safety according to the preferred embodiments of the present invention will be described in detail with reference to the drawings.

The present invention provides an embodiment of the tunnel inner wall pattern using the modified Mach band. 1 is a plan view showing a modified Mach pattern for explaining the pattern of the tunnel inner wall surface for driving safety according to an embodiment of the present invention, Figure 2 is an exemplary diagram applying the pattern of Figure 1 to the tunnel inner wall.

1 and 2, the tunnel inner wall pattern for driving safety according to the present embodiment has a first pattern layer 10 and a second pattern layer 20.

First, the pattern according to the present embodiment includes the first pattern layer 10.

The lower end of the first pattern layer 10 may be formed in a 'V-shape' shape or a 'sin curve' shape which is continuously connected, or may contact the bottom surface of the tunnel as shown in FIG. 1. On the other hand, the upper end of the first pattern layer 10 is preferably formed of 'V' type or 'sin curve' connected continuously.

When the curved pattern is formed on the inner wall of the tunnel, the driver can easily detect the driving speed, and can feel the stability and balance when driving. However, when only the first pattern layer 10 is formed, an optical illusion may occur on a horizontal basis. In other words, the road surface may be periodically raised during high speed driving, which may impair driving stability.

The pattern according to the present embodiment includes a second pattern layer 20. The second pattern layer 20 is formed in a transverse direction along the driving direction of the vehicle in contact with the upper surface of the first pattern layer 10 and is formed at a different brightness from the first pattern layer 10. When a plurality of pattern layers showing a difference in brightness are in contact with each other, a Mach band 40 is formed at an interface of each pattern layer. It is possible to detect the dynamic change of the pattern layer at the driver's perspective, thereby reducing the optical illusion and ultimately the safe operation in the tunnel.

The Mach band 40 is formed at an interface between the first pattern layer 10 and the second pattern layer 20 having a difference in brightness. The mach band 40 refers to a pattern in which the human vision looks like a stripe pattern when the patterns having different brightness levels are adjacent to each other. The Mach band effect is the Mach band effect. Specifically, the Mach band effect is a phenomenon in which the difference in brightness is greater due to the outer suppression at the boundary of the gray band having different brightness. Later-inhibit (Later-inhibit) each of the nerve cells that make up the optic nerve of the side inhibits the neighboring cells on both sides, it is also suppressed by the neighboring cells on both sides. Therefore, the initial output of each cell is the amount of inhibition minus the original response. As a result of this lateral suppression, the vicinity of the contour is emphasized and perceived. This is a kind of optical illusion.

Therefore, since the Mach band 40 is formed at the interface between the first pattern layer 10 and the second pattern layer 20, the Mach band 40 is more clearly and clearly perceived by the driver's vision, thereby causing a curiosity and a dynamic change. It enables tension and stable running.

The second pattern layer 20 may further include at least one third pattern layer 30 formed in contact with an upper surface of the second pattern layer 20 in a lateral direction and different in brightness from the second pattern layer 20. As the plurality of pattern layers are formed, the speed detection function and the driving safety of the driver can be further improved.

As long as the brightness of the third pattern layer 30 is different from the adjacent second pattern layer 20, the mach band 40 may appear at the portion where the patterns are in contact with each other, and the mach band effect may be expected. Patterns having such different brightness may be arranged in various ways. For example, the brightness of the second pattern layer 20 is higher than that of the first pattern layer 10, and the brightness of the third pattern layer 30 is higher than the brightness of the second pattern layer 20. It may be arranged so as to increase in brightness, that is, toward the upper pattern. On the contrary, the brightness of the second pattern layer 20 is lower than that of the first pattern layer 10, and the brightness of the third pattern layer 30 is lower than the brightness of the second pattern layer 20. That is, the brightness may be arranged toward the upper pattern.

The fourth pattern layer, the fifth pattern layer ... (the pattern layer after the third pattern layer) on the third pattern layer 30 in succession of one or more pattern layers having different brightness from the third pattern layer 30 May be disposed as one or more third pattern layers).

Subsequently, the first pattern layer 10 and the second pattern layer 20 are continuously connected to each other in a 'V' or 'sin curve' shape. When the vertical stripe pattern is applied to the inner wall surface of the tunnel, the visual speed of the driver is excellent, but confusion and optical illusion occurs, thereby increasing the visual fatigue of the driver. And when the horizontal stripe pattern is applied to the inner wall of the tunnel, the driver traveling inside the tunnel has a visually excellent sense of stability and balance, but the speed sensing ability is degraded.

However, when the pattern of the inner wall surface of the tunnel has a 'V' or 'sin curve' connected continuously, and a plurality of pattern layers having different brightnesses are formed to form a Mach band, the dynamic change of the pattern It can induce curiosity and improve speed sensing function, so it can be expected to prevent accidents in tunnels.

The first pattern layer 10 and the second pattern layer 20 may be formed in various ways on the inner wall surface of the tunnel.

For example, it can form by attaching a tile to a tunnel inner wall surface. In general, after installing the finishing material in the tunnel, the safety device is usually installed, but it is possible to form a pattern according to the present invention by attaching a colored tile to the tunnel inner wall using an adhesive. In other words, by attaching a plurality of pattern layers having different brightness in the form of 'V' or 'sin' curves, it is possible to obtain a finish effect and a safety device effect in a tunnel at no additional cost. In addition, the tiles have a smooth surface, so there is little contamination of foreign matters such as dust or automobile dust, and easy maintenance.

In another embodiment, the pattern including the first pattern layer 10 and the second pattern layer 20 may be formed by coating a paint on the inner wall surface of the tunnel. In the case of tunnels already completed and in use, it may be more desirable to paint the inner wall of the tunnel with paint than to apply the present embodiment using tiles to reduce construction time and cost. In this case, the color of each pattern layer can be expressed in various ways, and the contrast of each pattern layer can be made clear.

The present invention will be described in more detail with reference to the following examples and comparative examples. However, an Example is for illustrating this invention and is not limited only to these.
