Description

Technical Field

[0001] The present invention relates to the technical field of multi-lane traffic safety, and more specifically, to a traffic safety improvement system for the solar glare area of multi-lanes. Background Art

[0002] When a vehicle is running, 80% of traffic information is obtained by the driver through vision. During normal driving, the change of sunlight has a great impact on the driver's vision. When the driver's eyes are irradiated by high-intensity sunlight, it will cause vision loss and even loss of the ability to identify the road environment. Solar glare generally has the following three main adverse effects: 1) The excessive illuminance of the sun causes the road surface to appear grayish white, reducing the color difference between the road markings and the ordinary road surface, and hindering the driver's visual recognition of the road markings; 2) Traffic signs are generally at a relatively high position, and the excessive background light will cause obstacles to sign recognition; 3) The excessive sunlight in the distance causes the driver's line of sight to face downwards, further weakening the driver's ability to obtain road information in the distance and making it easier to speed. Therefore, this kind of solar glare is particularly adverse to the traffic safety of multi-lane sections at high speeds and is likely to cause traffic accidents.

[0003] Existing anti-glare facilities are mainly for anti-glare of vehicle lights, with less research on anti-glare of sunlight. And solar anti-glare mainly considers the area at the tunnel exit, and often uses methods such as sunshade panels or plant anti-glare, but these methods are difficult to be widely applied on ordinary roads.

[0030] Implementing the multi-lane traffic safety improvement system for solar glare areas of the present invention has the following beneficial effects:

[0031] 1. The present invention uses hollowed-out, light-transmitting, and combined designs to increase the surface brightness of the sign panel in the solar glare environment and enhance the visibility effect. The combined traffic information sign is not only composed of multiple small-sized traffic information signs spliced together, but also the text symbols adopt a hollowed-out structure with multiple plum blossom holes or petal-shaped small holes inside, which can significantly improve the surface brightness of the sign panel. The distance warning sign in the curved strip-shaped fluorescent sign adopts a light-transmitting structure, allowing part of the sunlight to pass through the sign for irradiation, which can significantly improve the visibility of the sign and meet the visibility requirements of drivers for small-sized roadside signs at close range.

[0032] 2. The present invention uses cylindrical, arc-shaped, etc. designs to optimize and improve the visibility of the guiding facilities at different angles, increase the visibility range, and the guiding facilities use fluorescent yellow-green, orange-yellow and other colors to improve the salience of the guiding facilities in the solar glare environment, further highlighting the road alignment contour.

[0033] 3. The present invention uses black, yellow and other markings and coatings to edge the ordinary white markings. Using the color difference makes up for the visibility defect of the white markings in strong sunlight, significantly improves the visibility effect of the markings, and clarifies the road rights. At the same time, arrow patterns and yellow reflective stickers are also applied to enhance the stimulation of road surface information and indicate the driving direction of the road, thereby enhancing the driver's sense of speed and direction.

[0034] 4. The present invention uses lifting and rotating designs to change the installation height and reflective angle of the vertical curved strip-shaped warning signs and cylindrical outline signs. It can not only be adjusted accordingly according to the road section alignment, but also change according to the solar glare angle, which is beneficial to improving the installation convenience of the guiding facilities and enhancing the reflective effect of the guiding facilities.

[0035] 5. The present invention uses the designs of step-by-step guidance and information repetition prompt. By setting curved strip-shaped fluorescent signs, road surface markings, traffic information signs, etc., the exit road information is increased, the redundancy of road information is increased, and many pieces of information are located at low positions such as guardrails and the ground, within the information acquisition range of drivers in solar glare, thereby improving the driver's information acquisition ability.

[0044] For a clearer understanding of the technical features, objectives, and effects of the present invention, the detailed implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] As Figure 1-6 shown, the traffic safety improvement system for multi-lane solar glare areas of the present invention includes a main road and an exit ramp provided on the side of the main road. An exit triangle area is formed between the main road and the exit ramp. Guardrails 10 are provided on both sides of the main road and the exit ramp. The system further includes a sign information guidance system, an induction facility system, an anti-glare cursor line system, and a road surface marking guidance system; the sign information guidance system is provided outside the guardrails on both sides, the anti-glare cursor line system and the road surface marking guidance system are provided on the road surface, and the induction facility system is provided on the guardrails 10 and in the exit triangle area.

[0046] The sign information guiding system includes a curved strip-shaped fluorescent sign 1 and a combined traffic information sign 2; the curved strip-shaped fluorescent sign 1 is arranged on the guardrails 10 on both sides before entering the exit ramp, and the combined traffic information sign 2 is arranged outside the guardrails 10 in the exit triangle area. The guiding facility system includes a cylindrical outline marker 11, a double-sided reflective outline marker 12, a vertical curved strip-shaped warning sign 13 and a single-sided luminous linear guiding sign 14. The cylindrical outline marker 11 is arranged above the guardrails 10 on both sides, the double-sided reflective outline marker 12 is arranged inside the guardrails 10, the vertical curved strip-shaped warning sign 13 is arranged in the middle of the exit triangle area, and the single-sided luminous linear guiding sign 14 is arranged on the guardrails 10 of the curve section of the exit ramp. The anti-glare cursor line system includes a bordered lane edge line 3, a bordered arrow-shaped marking 4, a bordered wide dashed line 5 and a yellow diversion line 6; the bordered lane edge line 3 is arranged at the edge of the driving lane; the bordered arrow-shaped marking 4 is arranged at the boundary between each lane on the main road; the bordered wide dashed line 5 is arranged at the boundary between the main line of the main road and the exit transition section; the yellow diversion line 6 is arranged in the middle of the exit triangle area. The road surface marking guiding system includes a bordered road surface text mark 7 and a bordered guiding arrow 8. The bordered road surface text mark 7 is arranged at the middle of each lane at a position 300 m away from the exit triangle area, at the middle of the middle lane and the right lane at a position 200 m away from the exit triangle area, and also at the middle of the exit transition section; the bordered road surface text mark 7 and the bordered guiding arrow 8 are arranged in sequence along the driving direction and correspond one by one.

[0047] For the combined traffic information sign 2, the information such as characters and symbols adopts a hollow structure; there are hollow holes 201 with a diameter of 0.1 cm to 0.5 cm inside the combined traffic information sign 2. The hollow holes 201 can adopt plum blossom holes or petal shapes. When the size of the information such as characters and symbols is larger, the size of the corresponding hollow holes 201 is also larger, so that a small amount of sunlight can pass through the holes in the characters, thereby increasing the brightness of the information on the sign board surface. The combined traffic information sign 2 is composed of a plurality of small-sized traffic information signs spliced together, and the splicing gap is 2 to 5 cm, so as to reduce the area of a single traffic sign board surface, further improve the surface brightness of the traffic sign, and the decomposed design of the traffic information can enable the driver to have a preliminary understanding of the information in advance and reduce the reading time of the information on the sign board surface.

[0048] The curved strip-shaped fluorescent signs 1 are respectively arranged at 300 m, 200 m and 100 m in front of the exit triangle area. And at 300 m and 200 m in front of the exit triangle area, the curved strip-shaped fluorescent signs 1 will be arranged on both sides of the road, but at 100 m in front of the exit, the curved strip-shaped fluorescent sign 1 is only arranged on the right side of the road. In this way, continuous and repeated exit previews can be given to the driver, and at a relatively low height on both sides, it can meet the driver's information needs for low positions when there is solar glare.

[0049] The curved strip-shaped fluorescent sign 1 is composed of a road name guiding sign 101 above and a distance warning sign 102 below. The road name guiding sign 101 includes the name of the exit road and an upper right arrow, and is arranged vertically, with a length of 0.8 - 1.6 m, a width of 0.3 m - 0.6 m, a circular arc cross-section, a fluorescent yellow-green background color, and black text and arrows. The distance warning sign 102 contains exit distance information, with both length and width of 0.3 - 0.6 m and a circular arc cross-section. It is made of a light-transmitting material, with a green background color and white text and symbol information. Using a light-transmitting structure design can improve the overall surface brightness of this facility. The curved strip-shaped fluorescent sign 1 adopts a circular arc structure design, which can improve the visibility of this facility at different angles, increase the visible range of this facility, and thus increase the probability that this facility can be accurately recognized and read.

[0050] The vertical curved strip-shaped warning sign 13 is composed of a circular arc-shaped aluminum plate 131 and a cylindrical bottom column 132. The circular arc-shaped aluminum plate 131 has a length of 0.8 - 1.2 m, a width of 0.3 - 0.5 m and a circular arc cross-section. The convex side of the circular arc-shaped aluminum plate 131 is pasted with a yellow and black reflective film. The vertical curved strip-shaped warning signs 13 are continuously set in the range from the nose end to the end point of the triangular area, and the setting interval is 2 - 5 m, which can improve the recognition distance of the exit triangular area in the sun glare environment, outline the triangular area contour, standardize the driving track, and improve the driver's vigilance and sense of speed. The cylindrical bottom column 132 is provided with a lifting device, which can adjust the height of the circular arc-shaped aluminum plate 131, so as to effectively make corresponding adjustments according to the road alignment and the sun glare angle. When the exit triangular area is in a convex curve section, the height of the circular arc-shaped aluminum plate 131 can be appropriately increased to allow the driver to discover the exit triangular area earlier; when the sun glare of the exit triangular area is strong, the height of the circular arc-shaped aluminum plate 131 can be appropriately reduced to reduce the influence of the sun glare. The yellow diversion line 6 is set on the road surface below the vertical curved strip-shaped warning sign 13, with a width of 0.2 - 0.4 m and a yellow color, to improve the recognition effect and warning property of the triangular area marking.

[0051] The cylindrical outline marker 11 is set above the guardrail 10 and consists of a cylindrical aluminum plate 111 and a base 112. The installation spacing of the cylindrical outline markers 11 is 8 - 16 m; the length of the cylindrical aluminum plate 111 is 10 - 15 cm. When set on the main line of the arterial road, the cross-section is a circle with a diameter of 8 - 16 cm. The cylindrical structure design can increase the retroreflective area, expand the visible range, and further enhance the surface brightness of the facility. When set on the exit ramp, the cross-section of the cylindrical aluminum plate is an ellipse with a major axis width of 16 - 32 cm and a minor axis of 8 - 16 cm, and the major axis direction is perpendicular to the forward direction, which can further increase the reflective area of the facility. On the outer surface of the cylindrical aluminum plate 111, orange-yellow reflective film is pasted in the range of 90° - 135° and faces the driver as much as possible. When the road alignment is a curve, the setting angle range of the orange-yellow reflective film should be increased, and the smaller the curve radius, the larger the setting angle range of the orange-yellow reflective film; only the range of 90° - 135° on the outer surface is pasted with orange-yellow reflective film, which can effectively save reflective materials. The base 112 is internally provided with a lifting device and a rotating device, which can change the height and reflective angle of the reflective surface of the cylindrical aluminum plate 111, facilitating the installation of the guiding facility and enhancing the reflective effect of the guiding facility. When this solar glare area is also a rain and fog prone area, the cylindrical outline marker 11 can be set as an active light-emitting type, and the size is increased to 1.5 - 2 times to improve the visibility of the facility.

[0052] The double-sided reflective outline marker 12 is set inside the guardrail 10, and the installation spacing is 8 - 16 m. In the curve section, the installation spacing is encrypted to 4 - 8 m; the length of the double-sided reflective outline marker 12 is 20 - 50 cm, the height is 8 cm - 16 cm, and the width is 5 - 10 cm; the reflective range of the double-sided reflective outline marker 12 is divided into an arc surface 121 and a rectangular surface 122. The arc surface 121 faces the driver's line of sight and is composed of fluorescent yellow-green reflective film, and the other side is a rectangular surface 122, which is composed of orange-yellow reflective film. The protruding design can increase the recognition area of the facility and enhance the retroreflective intensity. The double-sided and double-color design can not only expand the recognition angle but also enhance the salience, highlighting the linear outline of the road guardrail.

[0053] The single-sided light-emitting linear guide sign 14 is set above the curve guardrail of the exit ramp, with a yellow background and a black arrow. 1 / 5 - 1 / 3 of the head or 1 / 5 - 1 / 3 of the tail inside the black arrow is set as a yellow active light-emitting panel 141. The yellow active light-emitting panel 141 adopts a flashing light-emitting form during the solar glare period and a continuous light-emitting form at night. With such a structural design, it can not only improve the visibility and warning of the linear guide sign with a yellow background and a black pattern but also retain the color difference between the original black arrow and the yellow bottom plate.

[0054] The edge lane line 3 includes a white solid line 301, a black long edge 302, and a yellow rectangular reflective sticker 303; the white solid line 301 is set with a width of 10 - 25 cm; the black long edge 302 is set on the side of the white solid line 301 close to the vehicle driving direction, with a width of 5 - 10 cm, and is made of black paint, which can improve the visibility of the white marking against the grayish-white road surface background, highlight the contour of the lane line, clarify the driving space, and standardize the driving trajectory. The yellow rectangular reflective sticker 303 is set on the side of the black long edge 302 close to the vehicle driving direction, with a length of 10 - 30 cm, a width of 5 - 15 cm, and a spacing of 8 - 16 m. The spacing in the curve section is encrypted to 4 - 8 m. This further improves the prominence of the lane line on the grayish-white road surface, which can not only further highlight the lane line contour but also improve the driver's speed perception, facilitating the driver to keep in the lane and control the speed.

[0055] The edge arrow-shaped marking 4 includes a white long dashed line 401, a yellow arrow line 402, and a black arrow edge 403; the yellow arrow line 402 is set at the top of the white long dashed line 401, with the inner angle of the arrow being 45 - 135°, a length of 15 - 30 cm, and a width of 10 - 25 cm. Such a design can improve the color difference of the white long dashed line 401 on the grayish-white road surface, and the arrow pattern is conducive to reminding the driver to decelerate. The yellow color can ensure that the edge arrow-shaped marking 4 still has a good visibility effect in the sun glare environment. The black arrow edge 403 is set on the outer surface contour of the white long dashed line 401 and the yellow arrow line 402, with a width of 5 - 10 cm, and is made of black paint, which can highlight the contour of the white long dashed line 401 and enhance the visibility.

[0056] The edge wide dashed line 5 includes a white short dashed line 501, a yellow square reflective sticker 502, and a black short edge 503; the yellow square reflective sticker 502 is set at the top and bottom of the white short dashed line 501, with the set length and width being the same as the set width of the white short dashed line 501, which can enhance the driver's speed perception in the exit transition section and remind the driver to decelerate. The black short edge 503 is set on the outer surface contour of the white short dashed line 501 and the yellow square reflective sticker 502, with a width of 10 - 20 cm, and is made of black paint, which is conducive to improving the prominence of the white short dashed line 501.

[0057] The edge road surface text mark 7 contains the road name of the exit direction road, and a text edge 701 is set on the outer surface contour of the text; the text edge 701 is set with a width of 10 - 30 cm, and the larger the size of the text, the larger the corresponding text edge width. The color is orange-yellow or black, and the material can be a marking or paint. Such a design can highlight the contour of the road surface text and improve the driver's recognition and reading efficiency of the text in the sun glare environment.

[0058] The arrow form of the edging guiding arrow 8 in the rightmost lane is straight, and the arrows in the remaining positions drive right; a black guiding arrow edging 801 is provided on the outer surface of the arrow of the edging guiding arrow 8. The width of the guiding arrow edging 801 is set to be 10-20 cm, and the material is paint. Such a design can highlight the outline of the road surface text and improve the recognition and reading efficiency of the pattern by the driver in the sun glare environment.
