Description

{Illusion road show}

The present invention relates to a road surface display on which various kinds of guidance information are printed on a road surface, more specifically, a road surface display is recognized by a driver in a form standing vertically on a road surface, The present invention relates to an optical illusion effect road surface display capable of guiding a driver's gaze to a road surface display to assist in safe driving.

Many road markings are printed on the road surface of the current road. Such a road surface display allows the driver to learn the direction of the main base point, the classification of the left-right turning lane, and various information requiring attention.

These road markings are simply a stretch of characters in the longitudinal direction, with the horizontal lines closer to each other appear wider than the horizontal lines farther away, and the vertical lines are shown parallel to the lane of the road, There were disadvantages in that readability was poor because two or three rows were not recognized as parallel to each other.

Therefore, it is necessary to repeatedly print the road surface on the road surface in order to recognize the road surface display to the driver. Such road surface marks often pass unnecessarily when the driver does not concentrate in the forward direction. .

Therefore, it is necessary to display a road surface that allows the driver to accurately recognize the phrase, and also allows the driver to make an illusion that the phrase is moving, thereby naturally inducing the driver's gaze.

Accordingly, it is an object of the present invention to provide an optical illusion effect road surface display in which a road surface display is vertically erected on a road surface, which is recognized by a driver and improves the readability of characters.

In addition, the present invention provides an optical illusion effect road surface display which is set up in the driver's position and lie down on the road, guiding the driver's gaze to the road surface display, Have a purpose

The present invention relates to a road surface display, which is printed on a road surface and provides information to a remote driver in a phrase or a graphic form, the road surface display being projected with the same length in the driver ' s field of view And the printing length of the longitudinal side is longer than the printing length of the transverse side with respect to the longitudinal side, and the two adjacent longitudinal sides are printed on the road surface so as to form mutual acute angles.

Further, the present invention is characterized in that the print length y of the road surface display with respect to the length b of any longitudinal side set from the lowermost point of the road surface display projected onto the driver's view is expressed by y = ((XY) / (Ab) ) b.

Further, in the present invention, when the distance between the driver and the road surface display is X and the print range of the road surface display is S, the formation angle of the road surface display is θ = 2tan -1 ((S / 2) / X).

In the present invention, when the position of the driver is far away from the road surface display 1, the road surface display 1 appears to lie on the road surface. As the distance approaches the reference distance used in the diagram of the road surface display 1, When the driver 1 stands on the reference distance used in the diagram of the road surface display 1, the road surface display 1 is displayed to the driver in a form vertically standing on the road surface, The readability is improved.

Further, since the road surface display 1 is formed like a driver lying on the road and lying down on the road, it recognizes the moving object more quickly than the stationary object. .

FIG. 6 is a conceptual diagram illustrating a length ratio formula of a bottom side and an upper side of an optical illusive effect road surface display according to an embodiment of the present invention.

The optical illusive effect road surface display of the present invention can be applied to various road signs such as a school zone and a child protection zone on the road surface and a variety of guidance texts or figures such as guidance, From the viewpoint of the driver, the road surface marking (1) makes it possible to form the three-dimensional shape of the phrases so that the driver's attention can be raised and the readability of the phrase can be improved.

1 to 5, the road surface display 1 includes an arbitrary road surface projected to the driver's field of view at the reference distance between the driver and the road surface mark, The print length of the longitudinal side is formed longer than the print length,

Is printed.

More specifically, as shown in FIG. 2, when the driver's visual field height is set to Am and the height of the three-dimensionally displayed road surface display 1 is set to be Bm, a road surface display corresponding to the distance Xm between the driver and the road surface display 1 The printing length Ym of the printing unit (1) is given by the following equation using the similarity rule of the triangle. In this case, the distance between the driver and the road surface indicator 1 means the distance from the driver to the farthest position of the road surface indicator 1, and the height of the road surface indicator 1 means the road surface Means the total length from the uppermost point to the lowermost point of (1).

Equation

Figure pat00002

Figure pat00003

In the embodiment of the present invention, the case where the driver's visual field height is set to 1.3 m, which is the visual field height of the passenger vehicle driver, and the height of the road surface display 1, which is three-dimensionally displayed, is set to 39 cm will be shown and described. The present invention is not limited to the numerical limitation of the driver's visual field height or the three-dimensionally displayed road surface mark (1), as these can be selected by those skilled in the art within the scope of the formula.

If the distance between the driver and the road surface display 1 is 30 m according to the distance between the driver and the road surface display 1 according to the above equation,

Figure pat00004

9 m. In the same manner, the print lengths of the road marking 1 for the distances 15 m, 20 m, and 25 m, which are the reference between the driver and the road marking 1, are 4.5 m, 6 m and 7,5 m, respectively.

As shown in FIG. 3, in the driver's field of view, the length that is seen at the same interval also becomes longer as it goes up to the upper portion. The height of an arbitrary point b of the road surface display 1, which is three- The length of the point y on the actual road surface is given by the following equation. In this case, the height of an arbitrary point b means an arbitrary vertical length set from the lowermost point of the road surface marking (1).

Figure pat00008

That is, when the distance between the driver and the road surface marking 1 is 30 m, when the height of one line of characters printed on the road surface marking 1 is 10 cm at the top and bottom, The lower end of the top row is seen at 29 cm from the plane and the top of the bottom row is seen at 10 cm from the road surface,

Figure pat00009

Figure pat00010

It is displayed at 6.03m and 1.75m respectively. Therefore, since the uppermost portion of the uppermost row is displayed at 9 m, the print length of the uppermost row is 2.97 m and the print length of the lowest row is 1.75 m, which is about 1.7 times. That is, the print length of the road surface display 1 is printed so as to become longer from the lower end to the upper end, so that the driver's field of view is all the same length.

It is to be noted that the length of y with respect to the point b is such that when viewed from the driver's side, the vertical length shown on the actual road surface when viewed from the side of the road surface 1 About 1.75 m, and about 2.97 m at the top, which is about 17 to 30 times the length of the road.

In the above description, the vertical length of the road surface display 1 according to the driver's field of view has been described. However, the lateral angle of the road surface display 1 according to the field of view of the driver will be described below.

 When the distance between the driver and the road surface marking (1) is set to Xm and the print range of the road surface marking (1) is set to Sm as shown in 4, the lateral angle of the road surface marking (1) Follow.

Figure pat00011

That is, when the distance between the driver and the road surface display 1 is 30 m and the printing range of the road surface display 1 is 3.5 m, the left-

Figure pat00012

6.68 degrees. In the same manner, the left and right angles of the road surface indication 1 with respect to the distance 15m and 20m 25m, which are the reference between the driver and the road surface indication 1, are 13.31 degrees, 10 degrees and 8.01 degrees, respectively. When the left and right angles of the road surface marking 1 are set in accordance with the distance between the driver and the road surface marking 1, the right and left top edges of the road surface marking (1)

Since the lowermost left and right ends appear to be in the same position, the letters appear to be in a non-distorted shape.

Since the left and right angles of the road surface display 1 can be selected by a person skilled in the art within the range in which the above formula is applied according to the reference distance between the road surface display 1 and the driver and the print range of the road surface display 1, But the invention is not limited thereto numerically.

For example, in the above description, the case in which the road surface mark 1 is printed at a width of 3.5 m, which is a typical width of the road, is 15 m, 20 m, 25 m, 30 m Because the left and right angles of the road surface display 1 according to the reference distance of the road surface display 1 are changed according to the print range of the road surface display 1 as 12 degrees, 9 degrees, 7.2 degrees, 6 degrees, and the like. The left and right angles of the road surface display 1 are printed on each letter. In the case of a vowel such as "l" in which any vertical line from the uppermost point to the lowermost point of the road surface display 1, The angles formed by the side and the right side are printed differently from each other. the distance between the left side of the "l" vowel and the center of the road marking 1 is 1 m, and the right side of the vowel 1 is "1" when the "l" vowel is formed entirely from the upper end to the lower end of the road- And the center of the road surface mark (1) is 1.1 m, the left side and the right side of the "1" vowel and the lines forming the center of the road surface mark (1)

Figure pat00013

Figure pat00014

, The angle formed by the right and left sides of the "l" vowel having a width of 10 cm is 0.19 degrees.

If this is substituted into Equation (5) above,

Figure pat00015

That is, it follows the printing range formula of the road surface display 1 according to the driver's view. Accordingly, the left and right angles of the road surface display 1 according to the driver's view are formed in a fan-like shape, and the angles formed by the respective letters are added to each other to form the final left and right angles. The left and right angles indicate the angles formed by the left and right outermost sides of the road surface mark 1 printed.

On the other hand, the length s2m of the uppermost side from the driver with respect to the length s1m of the base line nearest to the driver of the "l" vowel in an arbitrary vertical row from the uppermost point to the lowermost point of the road surface display 1 in FIG. As shown, it can be derived as follows using the resemblance of a triangle.

Figure pat00016

Figure pat00017

Figure pat00018

At this time, since the printing lengths of the road surface markings 1 of 15 m, 20 m, 25 m and 30 m at the respective reference distances of 1.3 m are calculated as 4.5 m, 6 m, 7,5 m and 9 m respectively, And Y, and assuming that the length s1 of the base of the "l" vowel is 10 cm, the length s2 of the upper side of the "l"

Figure pat00019

Figure pat00020

Figure pat00021

Figure pat00022

In all cases it is the same as 14.29 cm. Therefore, according to the embodiment of the present invention, it is appropriate that the length of the upper side with respect to the base of the character or pattern having the same width is 1.43 times, regardless of the distance between the driver and the road surface display 1, The distance between the road surface 1 and the road surface 1 is shortened, and the length of the road surface display 1 is shortened so that the left and right angles of the "l"

However, even in this case, the above values can be selected by a person skilled in the art to the extent that the above formulas are applied. If the length of the road surface indication 1 varies depending on the driver's visual field height, And therefore, the numerical values are not limited in the present invention.

FIG. 6 shows an example of the illusion-effect road surface display of the present invention having the above-described structure. FIG. 6 is a view showing a road surface display 1 printed on an actual road in a case where the reference distance between the road surface display 1 and the driver is 20 m in the embodiment of the present invention. It can be seen that the side of the far side is formed to have a larger width and the side of each side is formed so as to form an acute angle with each other, and the upper row is formed to have a printing length longer than that of the lower row.

On the other hand, when the driver's visual field height such as a truck or a bus is higher than the visual field height of the driver of a general passenger car, the driver's position may be further away from the road surface display 1 as can be deduced from FIG. 1 or FIG. The driver of a truck or a bus can see the road surface display 1 of a three-dimensional shape farther from the driver than the driver of the passenger car.

As described above, the optical illusive effect road surface display of the present invention is such that when the driver's position is far away from the road surface indication 1, the road surface indication 1 appears to lie on the road surface, The road surface marking 1 is gradually raised as the reference distance approaches the reference distance and the road surface marking 1 is vertically erected on the road surface when the driver is positioned at the reference distance used in the illustration of the road surface marking 1. [ So that the legibility of the character is improved and the road surface display 1 is made to stand upright from the driver's position and lie down on the road so that the driver can recognize the moving object more quickly than the stationary object. It can help to drive safely by bringing attention.
