Description

Buffer over-identification for traffic solid line forecast

Technical Field

The invention relates to the field of traffic identification devices, in particular to a buffer excess identification for traffic solid line forecast.

Background

According to the current traffic marking standard, 2 or more motor lanes are driven in the same direction, white dotted lines are arranged on the road sections allowing vehicles to cross the lanes, and the line sections and the interval lengths are respectively 6m, 9m or 4m, 6m or 2m and 4m according to the difference of the design speed.

The method is characterized in that white solid lines are arranged on large bridge sections with strong side wind frequently, long and large tunnel sections with the width narrower than a roadbed, climbing lanes, sections with gradually changed lane widths, curves with poor sight distances, sections with sharp curves and steep slopes, sections close to pedestrian crossing lines, intersection entrance lanes and other sections needing no lane change, and lane change is not allowed.

With the increasing of the traffic flow, the distance between the running vehicles is smaller and smaller, the too small ground sight distance causes the boundary between the dotted line and the solid line seen by the driver to be too direct, the buffer is not excessive, the driver is easy to misjudge or the driver is confused after finding misjudgment, and then traffic accidents are caused, particularly on expressways or urban expressways, the problem is more serious.

Disclosure of Invention

The invention aims to provide a buffer over-mark for traffic solid line forecast, which improves the identifiability and reduces the misjudgment of a driver.

The technical scheme of the invention is as follows:

the buffer transition mark for traffic solid line forecast consists of a plurality of mark units in a dotted line shape; the identification unit consists of line segments and intervals of line segment ends; the length of the identification cells is gradually changed from the starting position to the ending position.

The length of the line segment gradually increases from the starting position to the ending position.

The interval length gradually decreases from the start position to the end position.

The interval length gradually decreases from the starting position to the ending position; the length of the line segment decreases gradually from the starting position to the ending position.

The color of the line segment at the starting position is red, and the color of the line segment at the ending position is red.

The initial position is provided with a first prompt rectangular frame group, and the termination position is provided with a second prompt rectangular frame group; the first prompt rectangular frame group comprises a first prompt rectangular frame, and the second prompt rectangular frame group comprises at least two second prompt rectangular frames.

The first prompting rectangular frame is perpendicular to the line segment, and the second prompting rectangular frame is perpendicular to the line segment.

A plurality of bulges are uniformly distributed in the first prompt rectangular frame and the second prompt rectangular frame.

The invention has the beneficial effects that: the invention belongs to a mark for buffering the transition of a broken line to a solid line on a traffic marking. The method for marking lines with excessive buffering is added into the two line types, so that the identifiability of the line marking change section is improved, the misjudgment of a driver is reduced, and the occurrence of traffic accidents is reduced. The method adds a solid line forecasting function to the road.

The present invention includes several indicia for alerting the driver that a full lane area is about to be entered. The method for marking the line segment length and/or the spacing distance in the dotted line is adopted, the proportion of the line segment part in the total length is gradually increased, and the solid line forecast for the driver is realized through the change of the marking line in the sight distance range near the vehicle body, so that the driver can know the lane change in advance, the misjudgment is prevented, and the accidents are reduced.

Detailed Description

Example 1: referring to fig. 1, the buffer over-identification for the traffic solid line forecast is a dotted line shape composed of a plurality of identification units; the identification unit consists of a line segment 1 and an interval 2 of the end part of the line segment; the segment length gradually increases from a start position 3 to an end position 4. Because the length of the identification unit is gradually changed, the automobile driving warning device has a good warning effect for a driver driving the automobile. The length of the line segment is gradually increased (the length of the rear line segment is longer than that of the front line segment), so that a better warning effect is achieved; when in use, the danger can be effectively avoided.

Example 2, as shown in fig. 2, the interval length gradually decreases from the start position to the end position. The interval is gradually reduced, so that a better warning effect is achieved; when in use, the danger can be effectively avoided.

Embodiment 3, as shown in fig. 3, the interval length is gradually decreased from the start position to the end position; the length of the line segment decreases gradually from the starting position to the ending position. The length of the line segment and the length of the interval are gradually reduced at the same time, so that the line segment and the interval in the dotted line are reduced, and a good warning effect is achieved; when in use, the danger can be effectively avoided; the preferred method that can make the interval reduce faster marks makes the sign more striking, and the warning effect is better.

The color of the line segment at the starting position is red, and the color of the line segment at the ending position is red. The line segments at the starting position and the ending position are more striking in red, and the prompting effect is better.

Example 4, referring to fig. 4, on the basis of example 1, a circular protrusion 5 is arranged at the center of the interval between every two line segments. The circular bulges are consistent in size, so that the change of interval length gradual reduction is more remarkable, and the prompt effect is enhanced.

Embodiment 5, referring to fig. 5, based on embodiment 1, a first prompting rectangular frame group is arranged at the initial position, and a second prompting rectangular frame group is arranged at the end position; the first prompt rectangular frame group comprises a first prompt rectangular frame 6, and the second prompt rectangular frame group comprises at least two second prompt rectangular frames 7; white paint is uniformly distributed in the first prompt rectangular frame and the second prompt rectangular frame. The driver is better prompted to enter the marked road section by setting a prompt line; the road prompt lines on the two sides are set to be different in number, so that the driver can observe the road prompt lines more conveniently.

The first prompting rectangular frame is perpendicular to the line segment, and the second prompting rectangular frame is perpendicular to the line segment. The first prompt rectangular frame and the second prompt rectangular frame are transversely arranged, so that the first prompt rectangular frame and the second prompt rectangular frame are more striking.

A plurality of bulges 8 are uniformly distributed in the first prompt rectangular frame and the second prompt rectangular frame. The bulge is arranged, so that the vehicle can vibrate to a certain degree to remind a driver of paying attention when entering the road section; the limited protrusions can adopt a hemispherical protrusion or a waist-shaped protrusion structure or a structure that the hemispherical protrusion and the waist-shaped protrusion are arranged in a staggered mode.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
