Description

A method for setting up retroreflective system in long expressway tunnel

technical field

The invention relates to the technical field of long and long expressway tunnels, in particular to a method for setting up a retroreflective system of long and long expressway tunnels.

Background technique

Traffic accidents frequently occur in tunnel sections, and the main cause of traffic accidents is speeding behavior, while 70% of expressway speeding behavior is induced by speed illusion (insufficient sense of speed). The main cause of accidents such as rear-end collisions and side wall collisions in tunnels is the lack of sense of distance, which can not accurately determine the distance between the car and the car in front and the distance between the car and the side wall, resulting in serious illusions. At the same time, the driver's driving trajectory deviates from the current lane, and the lane keeping ability is insufficient. The main cause is insufficient sense of direction. At the same time, when driving in tunnel groups, especially in long tunnels, the illumination inside the tunnel is low, the information is monotonous and lacks changes, which may easily cause the driver's visual fatigue and poor driving comfort.

Retroreflective technology is becoming more and more mature. Compared with traditional lighting, retroreflective lighting is an efficient and energy-saving lighting method. The concept of retroreflection refers to the reflection of reflected light returning to the light source from the opposite direction close to the incident light. Utilizing the above-mentioned principle of retroreflection of light and synthetically through artificial technology, a new type of material that can achieve the effect of light retroreflection - retroreflective material is formed. Retroreflective lighting is to increase the local brightness and contrast of obstacles through retroreflective materials, thereby improving the visibility of obstacles. As a retroreflective material, the reflective ring has been applied in Guizhou, Zhejiang and other places in recent years, and its functions of improving the tunnel outline, enhancing the sense of direction, and enhancing the induction have also been recognized.

The road tunnel retro-reflective system is to apply retro-reflective technology to the design of tunnel traffic safety facilities to achieve the purpose of increasing the viewing distance, improving local brightness, improving the tunnel visual environment, ensuring traffic safety and reducing energy consumption. The traditional lighting of highway tunnels is to install lighting lamps on the upper part of the tunnel, which consumes a lot of energy and is not very helpful for the visual recognition of tunnel road information. Therefore, there is a need for a lighting method that can improve the local brightness of the tunnel pavement, has low energy consumption, and is convenient for later maintenance.

Installation, the setting distance is 150~300m/channel,

Set a reflective strip 2 with a width of 8cm on the lower part of the side wall, made of aluminum or stainless steel consistent with the outline of the tunnel, paste a layer of super reflective film on the facing vehicle surface, install it along the inner outline of the tunnel, and set the height to 2-3m.

The setting interval is 30-60m/track, the height of side wall guiding signs 3 is about 2-3m, and the setting spacing is 30-60m/track, and the contour marking 4 is set on the tunnel side wall and maintenance road, and the setting spacing is 6-12m/each , the bottom discs of the cat's eye road stud 5 are installed on the asphalt concrete road on both sides of the road, and the setting interval is 6-12m per piece. The spacing is 150-300m/group. The middle section is for the visual needs of speed, distance, direction and comfort, as well as the visual recognition requirements for road surface information under low brightness conditions. Therefore, reflective ring 1 is used to set a large spacing, and four kinds of musical note symbols are set on the ground. Lines (compared with conventional numbers and characters, musical notes are more in line with people's aesthetic needs and are more attractive to people), attracting the driver's attention to the ground, enhancing the sense of direction and inductiveness, and forming a continuous repetitive rhythm , gradual rhythm, undulating rhythm, interlaced rhythm, and finally form a rhythmic visual reference system.

Step 4: For tunnels with a length of 2000-3000m, apply colored high-grade reflective film on the facing vehicle surface of the reflective ring to form a colored reflective ring 1, set up a theme color reminder segment every 1000m, and set two color reflective rings in succession for each reminder segment ( Adjacent reminder segments use different theme colors).

Step 5. For extra-long tunnels (>3000m), set a theme color reflective ring and reflective strips every 3km as the wake-up section, and set smooth rhythm patterns on the side walls of the tunnel. Different wake-up sections correspond to different rhythm patterns. Length For 200-400m, use colored low-frequency reflective rings 1, low-frequency note markings 6, colored mid-frequency reflective strips 2, mid-frequency rhythmic side wall guide signs 3, high-frequency rhythmic contour marks 4, and high-frequency cat's eye road studs 5.

Preferably, the color of the colored reflective ring 1 is composed of commonly used red, yellow and green, and a theme colored reflective ring 1 area is set every 1 km as a reminder segment, and a theme colored reflective ring 1 and reflective strips are set every 3 km 2 as a wake-up segment. Adopt such structure setting, set colored reflective ring 1 area as reminding section (wake-up section), to alleviate the driver's visual fatigue in the middle of the tunnel, remind the driver to be in the position of reminding section (wake-up section) in the middle of tunnel simultaneously.

Preferably, the color of the outline marker 4 in the tunnel is yellow on the left and white on the right. With such a structural arrangement, the driver's sense of direction is further enhanced.

Preferably, the note markings 6 include four different note markings. With such a structural setting, it is easier to attract people's attention than conventional symbols. Four kinds of road surface note markings are used to enable the driver to maintain a certain sense of rhythm during the driving process. While ensuring the sense of direction, it increases the driving Comfortable and has a certain aesthetics.

Preferably, attention should be paid to the maintenance and maintenance of the retroreflective safety device in the present invention, and attention should be paid to replace the reflective film when the reflective coefficient drops to more than 70% of the designed value.

Embodiments of the present invention have been described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific embodiments, which are only illustrative, rather than restrictive, and those of ordinary skill in the art will Under the enlightenment of the present invention, many forms can also be made without departing from the gist of the present invention and the protection scope of the claims, and these all belong to the protection scope of the present invention.
