- the road surface display 1 is a horizontal side with respect to any horizontal and vertical sides projected by the same length in the driver's field of view at the reference distance between the driver and the road surface display
- the print length of the longitudinal side is formed longer than the print length, and two adjacent longitudinal sides are printed on the road surface to form mutual acute angles.
- the road surface display 1 when the driver's viewing height is set to Am and the height of the road surface display 1 to be seen in three dimensions is set to Bm as shown in FIG. 2, the road surface display according to the distance Xm between the driver and the road surface display 1 is shown.
- the print length Ym in (1) is obtained by the following equation using the triangle-like law.
- the distance between the driver and the road marking 1 means the distance from the driver to the furthest position of the road marking 1
- the height of the road marking 1 is a road marking projected onto the driver's field of view. It means the total length from the highest point to the lowest point of (1).
- the height of the driver's field of view is set to 1.3 m
- the height of the field of view of the passenger car, and the height of the road surface display 1 to be seen in three dimensions is set to 39 cm
- the formula can be selected by those skilled in the art within the range to which the formula is applied, the height of the driver's field of view or the height of the road marking 1 to be seen in three dimensions is not numerically limited in the present invention.
- the printing length of the road marking 1 according to the distance between the driver and the road marking 1 according to the above equation is, when the distance between the driver and the road marking 1 is 30m,
- the print lengths of the road markings 1 for the distances 15m, 20m and 25m serving as the reference between the driver and the road markings 1 are 4.5m, 6m and 7,5m, respectively.
- the lengths shown at equal intervals in the driver's field of view also increase the length at which they are printed at the top, and at a height of an arbitrary point b of the road marking 1 to be seen in three dimensions.
- the length of point y on the actual road surface is given by the following equation.
- the height of the arbitrary point b means an arbitrary longitudinal length set from the lowest point of the road marking 1.
- the top and bottom rows are the same. To see the height, the bottom of the top row is shown 29cm from the road surface, and the top of the bottom row is shown 10cm from the road surface,
- the printing length of the uppermost row is 2.97m
- the printing length of the lowermost row is 1.75m, which is about 1.7 times the ratio. That is, the print length of the road marking 1 must be printed to be longer from the lower end to the upper end so that the driver can see the same length in the driver's field of view.
- the length of y with respect to point b is that when the driver wants to make it look like a square with all the lengths and widths of 10 cm, the length of the length shown on the actual road surface is at the bottom of the road marking 1. It is about 1.75m and about 2.97m in the upper part, and the longitudinal side is 17 to 30 times longer than the horizontal side.
- the left and right angles ⁇ of the road surface display 1 according to the driver's field of view are as follows.
- the left and right angles of the road surface display 1 with respect to the distance 15m and 20m 25m serving as the reference between the driver and the road surface display 1 are 13.31 degrees, 10 degrees, and 8.01 degrees, respectively.
- the driver's field of view at the distance is the same as the top left and right ends and the bottom left and right ends of the road surface display 1. Since it appears to be in position, the letters appear to be in an undistorted shape.
- left and right angles of the road marking 1 may be selected by a person skilled in the art within the range where the above formula is applied according to the reference distance between the road marking 1 and the driver and the printing range of the road marking 1, It is not intended that the invention be numerically limited.
- the road marking 1 is printed on a width of 3.5 m, which is the width of a normal road.
- the road marking 1 is printed at a distance of 3.15 m from a lane of the road, 15 m, 20 m, 25 m, and 30 m are printed.
- the left and right angles of the road surface display 1 in accordance with the reference distance are 12 degrees, 9 degrees, 7.2 degrees, 6 degrees, and the like, respectively, and are changed according to the printing range of the road surface display 1.
- the left and right angles of the road marking 1 are also applied to each letter and printed, and in the case of a vowel such as "l" for any vertical line extending from the top point to the bottom of the road marking 1, the left The angle formed by the side and the right side is printed differently.
- the "l" vowel is formed entirely from the upper end to the lower end of the road marking 1, 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 "l” vowel.
- the distance between the center of the road surface display and the road surface display 1 is 1.1 m
- the line between the left side and the right side of the "1" collection and the right center side of the road surface display 1 and the angle formed are respectively.
- the angle formed by the left and right sides of the "l" vowel having a width of 10 cm is 0.19 degrees.
- the left and right angles of the road surface display 1 are formed by adding the angles formed by the letters in a fan shape to form the final left and right angles of the road surface display 1.
- the left and right angles refer to angles formed between the left and right outermost sides on which the road surface display 1 is printed.
- the length s2m of the upper side farthest from the driver for the length s1m of the bottom side closest to the driver of the "l" vowel in any vertical row from the uppermost point to the lowermost point of the road marking 1 is shown in FIG. 5. As shown in the figure, it can be derived as follows using the similarity of triangles.
- the print lengths of the road markings 1 of 15m, 20m, 25m, and 30m of the reference distances for the driver's field of view height of 1.3m were calculated as 4.5m, 6m, 7,5m, and 9m, respectively. Substituting into and Y, and suppose that the length s1 of the bottom side of the "l" vowel is 10 cm, the length s2 of the upper side of the "l" vowel,
- the length of the upper side with respect to the lower side of the character or the pattern appearing in the same width is suitably about 1.43 times regardless of the distance between the driver and the road marking 1, which is the driver and the road marking. It is because the printing length of the road surface display 1 is shortened by the distance between (1) shortening and the left-right angle of a "l" vowel becomes large.
- the above numerical values can be selected by those skilled in the art within the range to which the above formulas are applied, and if the length of the road marking 1 is varied according to the driver's viewing height, the length of the upper side to the base side is changed. It is also possible to vary, so the numerical value is not limited in the present invention.
- FIG. 6 is a scaled down view of a road marking 1 printed on an actual road in a case where the reference distance between the road marking 1 and the driver is 20 m in an embodiment of the present invention. It can be seen that the far side is formed to have a greater width, and each of the longitudinal sides is formed at an acute angle to each other, and the top row is formed to have a longer print length than the bottom row.
- the driver's viewing height is higher than that of a general passenger car, such as a truck or a bus
- the driver's position may be further from the road surface display 1 as inferred from FIG. 1 or 2.
- a driver such as a truck or a bus can see a three-dimensional road surface display 1 at a position farther than a passenger car driver.
- the optical illusion effect road surface display of the present invention as described above appears to be lying on the road surface when the driver's position is far from the road surface display (1), and used for the schematic of the road surface display (1).
