Detailed Description
The invention is further described below with reference to specific examples:
in this embodiment, the driving direction is taken as the front, the inner finger is located on one side of the left hand and the outer finger is located on one side of the right hand during left turn, and the inner finger is located on one side of the right hand and the outer finger is located on one side of the left hand during right turn. The radius of the curve section is the radius of the center line of the lane, and the lane width is 3.5 m.
Referring to fig. 1: the method for designing the optical illusion deceleration marked line of the road curve section comprises the following steps:
s1: setting an auxiliary central line:
taking an arc line with the radius of 400-600 m as an auxiliary center line 1, and enabling a curve midpoint (QZ) of the auxiliary center line 1 to be intersected with a road center line curve midpoint (QZ) of a road curve section; in this embodiment, the radius of the auxiliary center line 1 is set to 500 m.
S2: setting an inner auxiliary line and an outer auxiliary line:
the auxiliary center line 1 is respectively shifted to the two sides to form an inner auxiliary line 5 and an outer auxiliary line 2, the distance between the curved middle point (QZ) of the inner auxiliary line 5 and the curved middle point (QZ) of the inner lane line 6 is 0.35-0.45 m, and the distance between the curved middle point (QZ) of the outer auxiliary line 2 and the curved middle point (QZ) of the outer lane line 3 is 0.35-0.45 m. In the present embodiment, the distance between the midpoint of curvature (QZ) of the inner side auxiliary line 5 and the midpoint of curvature (QZ) of the inner side lane line 6 is 0.4m, and the distance between the midpoint of curvature (QZ) of the outer side auxiliary line 2 and the midpoint of curvature (QZ) of the outer side lane line 3 is 0.4 m.
The offset is a movement and is compensated, in this embodiment, the distances between each point on the outer auxiliary line formed by the offset and the corresponding point on the auxiliary center line are equal, and the distances between each point on the inner auxiliary line formed by the offset and the corresponding point on the auxiliary center line are equal.
S3: drawing a deceleration marked line:
and drawing one-to-one corresponding deceleration marked lines 4 between the inner lane lines and the inner auxiliary lines and between the outer lane lines and the outer auxiliary lines respectively, wherein one end of each deceleration marked line is connected with the corresponding side lane line, and the other end of each deceleration marked line extends towards the auxiliary central line and is connected with the corresponding side auxiliary line. The distance between two adjacent deceleration marked lines along the length direction of the lane is equal or unequal, and the sum of the transverse width of the deceleration marked line positioned on the inner side of the lane and the transverse width of the corresponding deceleration marked line positioned on the outer side of the lane is constantly equal to 0.7-0.9 m. In the present embodiment, the sum of the lateral width of the deceleration mark line located on the inner side of the lane and the lateral width of the corresponding deceleration mark line located on the outer side of the lane is constantly equal to 0.8 m.
The distance between two adjacent deceleration marked lines along the length direction of the lane can be equal or unequal. In the embodiment, when the radius of the curved road section is 125-699 m, the distance between two adjacent deceleration marked lines is equal, the distance is 2-6 m, and specifically, when the radius of the curved road section is 125-399 m, the distance between two adjacent deceleration marked lines is 6 m; when the radius of the road curve section is 400-599 m, the distance between two adjacent deceleration marked lines is 2-6 m; when the radius of the road curve section is 600-699 m, the distance between two adjacent speed reduction marked lines is 6 m.
When the radius of the curve section is 700 m-1000 m, the distance between two adjacent deceleration marked lines is reduced to 1m from 6.2m in a gradually reducing mode. In one embodiment, the radius of the curved section is 700-1000 m, and the distance between two adjacent deceleration marked lines is 6.2m, 5.9m, 5.6m, 5.3m, 5.0m, 4.7m, 4.5m, 4.3m, 4.1m, 3.9m, 3.8m, 3.6m, 3.5m, 3.3m, 3.2m, 3.0m, 2.9m, 2.7m, 2.6m, 2.4m, 2.3m, 2.1m, 2.0m, 1.8m, 1.7m, 1.5m, 1.4m, 1.2m, 1.0m along the traveling direction.
The optical illusion deceleration marked line drawn by the method can create the illusion with the changed radius, so that the radius of the road curve section with different radii looks like 500m, the linear index of the road curve section better meets the expectation of a driver, and the misoperation of the driver is reduced.
Referring to fig. 2 and 3, when the turning radius is 500m, the marked lines on both sides have the same width, which is always 0.4 m. The running speed coordination is optimal. When the radius is larger than 500m, the numerical value of the transverse width of the left side and the right side of the marked line is changed, so that the driver mistakenly thinks that the radius is smaller than the actual radius value and the lane is compressed, and the tension is increased, so that the deceleration measure is taken, and the behavior of 'cutting the curve' of the driver in the curve can be prevented; when the radius is less than 500m, the change of the lateral width on the left and right sides of the marking line can cause the illusion that the radius value is larger than the actual radius value and the tense feeling can be properly relieved. Therefore, the optical illusion speed control mark line in the curve section is not symmetrically drawn, and the driver can generate the illusion of the change of the radius of the curve by changing the size of the transverse width of the left side and the right side of the mark line.
Furthermore, the invention also provides the optical illusion deceleration marked line designed by the method.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and although the present invention has been described in detail by referring to the preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of the present invention can be made without departing from the spirit and scope of the technical solutions, and all the modifications and equivalent substitutions should be covered by the claims of the present invention.
