Description

Traffic landscape design method for urban cross-river bridges based on multi-frequency color information

technical field

The invention relates to the technical field of urban bridge traffic design, in particular to a traffic landscape design method for urban cross-river bridges that improves the driver's vehicle speed control and vehicle distance maintenance capabilities, thereby realizing the unification of urban cross-river bridge landscape coordination and bridge traffic safety benefits.

Background technique

It is common for vehicles to overspeed on bridges across rivers in cities, and accidents of rear-end collisions and collisions with safety guardrails occur frequently. Urban river-crossing bridges are generally relatively long, ranging from hundreds of meters to several thousand meters. The traffic safety facilities and landscape on the bridge are generally insufficient, the environment is monotonous, and there are few reference objects; drivers lack a sense of direction and speed, resulting in widespread speeding. Vehicles are driving on bridges with high speed and small distance between vehicles. When the vehicle in front stops or decelerates in an emergency, it is very easy for the following vehicles to fail to avoid in time, resulting in a rear-end collision accident of a group of vehicles. Domestic statistics on urban cross-river bridge accidents show that speeding is the main cause of accidents, and rear-end collisions and collisions with roadside guardrails are the main accident forms, accounting for more than 60% of the total accidents.

The existing urban river-crossing bridge landscape settings are not highly targeted, and it is necessary to design the urban river-crossing bridge landscape according to the accident causes and accident patterns. Landscape is a comprehensive visual impression formed in the mind by what is seen at the viewpoint. The existing urban landscape design of bridges across the river often stays at the aesthetic level, largely because the cognition of road landscape only stays on the road itself and Beautification of its subsidiary structures. In the planning, design and evaluation of the road landscape, we should not only focus on the aesthetic level of the road landscape itself, but should also add the functional research on the visual perception of the users of the road landscape itself. Therefore, it is necessary to improve the driver’s ability to recognize the railing and the vehicle in front under different illumination environments, specifically the ability to control the speed of the vehicle and maintain the distance between vehicles, according to the accident form (rear collision, collision with the side wall) and the cause of the accident (overspeed). To achieve the unity of landscape coordination and safety of urban cross-river bridges.

The vehicle speed control method based on edge rate is applied. Edge rate is considered to be an important visual factor affecting speed perception. The edge rate is the relative speed at which points in space pass through the edge of the field of vision when a person is moving. Scholars at home and abroad use the edge rate to "unconsciously" use speed control in traffic to improve the speed perception of the highway environment. Master of Engineering Thesis, 2008) Through psychophysical experiments, it was found that when the edge rate is less than 2Hz or greater than 32Hz, the driver will underestimate the speed, and when the edge rate is 4Hz-16Hz, the experimenter will overestimate the speed. The rate of 12Hz is overestimated by more than 30%.

The influence of color on driving safety. Color permeates every corner of road traffic. For drivers, at least 80% of traffic information comes from vision, and color is the easiest to perceive visually (its priority is greater than shape, size, and content), and it directly affects safe driving . The current roads are generally gray or black. Gray and black have a calming effect on the human nervous system, but staring at the monotonous gray road surface for a long time will make the driver's attention dull, induce fatigue, and even drowsiness. The risk of traffic accidents increases. The scenery around the urban river-crossing bridge is mostly gray and light blue, and the contrast between the color of the guardrail and the background is very small. Then, on the one hand, the guardrail cannot play a role in visual guidance, and the driver's sense of direction is reduced. On the other hand, in the Under high-speed driving, especially in dim light conditions, the driver may not be able to see the guardrail clearly or cannot correctly judge the position of the guardrail, which will reduce the sense of distance, resulting in traffic accidents (especially rear-end collision accidents).

Human eyes have different sensitivities to different colors under different illuminance. Studies have shown that vision is accomplished by the joint activities of the eyes, optic nerve and visual center. The main part of the visual system is the eyes, which are the receptors for vision. The process of people feeling the stimulation of light is that the light reaches the retina through the pupil, and different visual cells in the retina transmit the light to the optic nerve, and the optic nerve then transmits the stimulation to the relevant parts of the brain. There are two main types of visual cells in the retina, one is rod cells, and the other is cone cells. Among them, rod cells are distributed far away from the center of the retina. They work on low-level lighting and mainly play a role in distinguishing black and white. It is most sensitive to the green and blue parts of the spectrum, and is sensitive to extremely weak stimuli; while the cone cells are more distributed in the center of the retina, and work on high-level lighting. The main function is to distinguish colors, and they are sensitive to yellow and red in the spectrum. The most sensitive, mainly to identify the spatial position and require a keen look at objects. There are few types of landscapes in the existing urban bridges across the river, the density is low, and the color setting is invariable, very monotonous, it is not easy to arouse driver excitement, and it is also easy to induce fatigue driving.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the monotonous traffic landscape setting of the existing urban cross-river bridges, few types of landscapes, low density, and constant colors, and it is difficult to guarantee the driver's accurate cognition of the traffic environment under various illumination conditions. , to provide a traffic landscape design method for urban cross-river bridges based on multi-frequency color information, which helps drivers maintain a clear driving state and improves the driver's cognitive ability under different illumination conditions.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:

A landscape design method for urban river-crossing bridges based on multi-frequency color information. On urban river-crossing bridges with a speed limit of 60-80 km/h, at least two lanes are set in both directions. There is a separation zone between them, sidewalks on the outside of the edge lanes, and bridge railings (4) on the outside of each sidewalk; lampposts are set on the sidewalk; it is characterized in that: make full use of various facilities on the road surface, and set high-frequency, medium-frequency, and low-frequency colors information, using the color band settings of various facilities to comprehensively improve the driver's sense of speed, direction, and distance; the specific steps are as follows:

On the lower edge of each lamp post in the direction of the two-way traffic lane, set yellow and black and blue and white lamp post facade marking lines (3) at intervals, and the corresponding road surface setting and traffic lane direction Vertical dotted line-shaped horizontal optical illusion markings (5), protruding road signs (1) are set every 12.5-17.5m along the isolation zone and along the outermost edge of the traffic lanes in each direction, and the marking lines on the facade of lampposts (3), horizontal Optical illusion markings (5) and protruding road signs (1) together form an intermediate-frequency visual information flow with a spatial frequency of 0.5-2.0 Hz to enhance the driver's sense of direction;

Curbstones are set on the outer side of the protruding road signs (1) on the outermost edge of each traffic lane and at the interval between the sidewalk; yellow and black or blue and white roadside elevation marking lines (2) are set on the lower edge and top of the curbstones to form a space The frequency is 8-12hz spatial high-frequency visual information flow, which improves the driver's sense of speed;

At every 4 lampposts in the forward direction of the two-way traffic lane, 2 white V-shaped fold lines (6) with sharp ends facing the forward direction and continuously stacked front and back are set horizontally on the road surface of each two-way traffic lane to form a vehicle distance confirmation line, bridge railings (4) Set it to yellow or blue to jointly form a low-frequency visual information flow with a spatial frequency of 0.125-0.25Hz to improve the driver's ability to confirm the distance between vehicles.

According to the above technical solution, the three protruding road signs (1) corresponding laterally along the isolation zone and along the outermost edge of each traffic lane are located on the same straight line.

According to the above technical solution, the horizontal optical illusion markings (5) on the two-way carriageway are located on the same straight line.

According to the above technical solution, the distance between adjacent lampposts is 25-35m.

According to the above technical scheme, the lower part of the lamp post is painted with yellow and black or blue and white, each with a coating height of 0.5m, and a total of 3 lines are arranged, with a total height of 3m.

According to the above-mentioned technical scheme, the two white V-shaped broken lines (6) on the two-way traffic road surface respectively correspond to and laterally lie on the same straight line.

According to the above technical scheme, the roadside elevation marking line (2) changes from yellow and black to blue and white every 100-140m; when the roadside elevation marking line (2) is yellow and black, the bridge railing (4) is Yellow; when the roadside elevation marking line (2) is blue and white, the bridge railing (4) is blue.

According to the above-mentioned technical scheme, for the cross-river bridges with a length of more than 1000m, red and white safety colors shall be added in addition to the safety colors of yellow and black and blue and white. The railing (4) is white); change between 3 tones to enrich the landscape of the cross-river bridge and relieve driver fatigue.

In the method of the present invention, the intermediate frequency information to improve the level of direction awareness is mainly the marking line (3) on the facade of the lamppost set at the lower part of the lamppost, the set spatial frequency is 0.5-2.0Hz, and the distance between the lampposts is 25-35m; the lower part of the lamppost The coating is yellow and black (or blue and white) alternately, the height of the yellow and black (or blue and white) coatings is 0.5m each, a total of 3 lines are set up for each, with a total height of 3m; The line segment is 45cm long, with an interval of 45cm (refer to the deceleration marking method of expressway toll stations in the new national standard), and every 6-15m, set up medium-frequency raised road signs on the outside of the edge line of the urban cross-river bridge and in the road. The intermediate frequency information is stimulated to provide a medium psychological response to satisfy the driver's sense of direction and rhythm.

In the method of the present invention, the low-frequency information for improving the perceived level of vehicle distance is mainly the vehicle distance confirmation marking line (that is, the white broken line (6)) and the color of the bridge railing, which is mainly realized by setting the road surface marking line and changing the painting color of the bridge railing. Set the spatial frequency to 0.125-0.25Hz, and the spacing to 100-140m (one for every four lampposts). A group of vehicle distance confirmation markings is composed of 2 consecutive markings. The bridge railings are painted in yellow (or blue), which is changed every 100-140m; the road distance confirmation markings are white broken lines: the total width of the markings is 300cm, the line width is 45cm, and the distance between two markings is 5m; low-frequency information Streaming can ensure that the driver can confirm the distance between the vehicle and the vehicle in front while driving, satisfying the driver's sense of distance.

In the method of the present invention, the high-frequency information to enhance the level of speed perception mainly includes the lower edge of the curb and the top yellow and black (blue and white) marking lines (2) on the road side elevation, the spatial frequency of which is 8-12 Hz, and the sidewalk curb The width of the top marking line is 0.2-0.3m, and the spacing is 1.5-3m. The setting of high-frequency sensitive information flow can provide instantaneous speed perception, increase the driver's visual psychological response, and ensure that the driver's perceived speed is greater than the physical speed during vehicle operation.

According to the driving process, under the action of high-frequency information (8-12Hz), the perceived speed is greater than the physical speed, while under the medium-frequency and low-frequency conditions (<2Hz), the perceived speed is lower than the physical speed. In the driving environment, the ideal perceptual speed should be slightly larger than the physical speed (<10% or 5%). Therefore, it is necessary to combine high-frequency, medium-frequency, and low-frequency information to set up a multi-frequency visual information flow to achieve the perception speed and physical speed. The speed is coordinated and the purpose of speed control is achieved.

The present invention aims at the accident form (rear-end collision, crashing into the safety guardrail) and the cause of the accident (overspeed) of the bridge across the river in the city. According to the fact that the human eye is more sensitive to short-wavelength colors (green, blue) under low-illuminance conditions, it is more sensitive to short-wavelength colors (green, blue) under high-illuminance conditions. The cognitive characteristics that are sensitive to long-wavelength colors (red, yellow) are set up for the urban cross-river bridge traffic landscape. Make full use of bridge pavement, roadside curbs, railings, lampposts and other landscapes to build a variety of colors and frequencies of visual information flow, stimulate the driver's nervous system, help the driver maintain a clear driving state, improve the driver's Cognitive ability under different illumination conditions.

By setting curb façade marking lines of different frequencies and colors, road horizontal markings, lampposts and railing coatings of urban cross-river bridges, the driver's sense of speed, direction and distance during driving can be comprehensively improved, thereby To achieve the purpose of standardizing and guiding driving behavior and effectively avoiding accidents. In urban bridges across the river, yellow and blue are the main colors, and yellow and blue urban bridge railings are set; black and white are used as auxiliary colors, and yellow and black ( or blue and white) to improve the driver's ability to adapt to light and shade under different illumination conditions and improve the driver's sense of driving space.

According to the indoor simulation experiment, the urban cross-river bridge traffic project using this method, when the vehicle speed is 60-100km/h, the driver's perceived speed is approximately equal to the physical speed, and at the same time, the perceived collision time (collision time is the key factor for maintaining the distance between vehicles) ) is also approximately equal to the collision time, and the difference is about 5%; it shows that the traffic landscape of urban cross-river bridges designed according to this method can comprehensively improve the driver's sense of speed, direction, and distance.

Compared with the prior art, the beneficial effects of the present invention are as follows:

1) Designing small-scale, high-frequency yellow-black (or blue-white) facade marking lines on sidewalk curbs of urban cross-river bridges can improve the driver's instantaneous perception speed;

2) Set yellow and black (or blue and white) facade marking lines at the lower part of the medium-frequency lampposts on urban cross-river bridges, and at the same time set horizontal optical illusion marking lines of the same density on the tunnel road surface, which work together with the raised road signs on the road surface to improve The driver's sense of direction and distance.

3) The color change of the railings of bridges across the river and sidewalk curbs in the city and the setting of low-frequency distance confirmation lines on the road surface can increase the driver's sense of distance and eliminate fatigue.

4) This method mainly uses yellow and blue as the main colors, and black and white as auxiliary colors. It can use the driver's different visual response mechanisms to light under high and low illuminance. It is more sensitive to long-wavelength colors under high illuminance. It is more sensitive to short-wavelength colors, which can improve the driver's sense of space under different illuminance.

5) The yellow and blue railing coatings used in this method, and the blue and white and yellow and black curb façade marking lines can effectively reduce the driver's visual fatigue and enhance the contrast with the surrounding environment of the bridge. At the same time, considering the driver's different reactions to light under high and low illumination, when the human eye is sensitive and adaptable at dusk, the blue color is extremely bright, and the yellow color is darker. The use of blue and white, yellow and black can effectively enhance vision adaptability.

6) This method is mainly aimed at traffic landscapes with few reference objects and unchanging colors in general urban cross-river bridges; through color setting, the driver's sense of direction and speed can be improved to achieve the unity of landscape coordination and safety of urban cross-river bridges.

7) This method adopts low-cost road marking and visual guidance system, does not involve large-scale road infrastructure, has low investment, easy construction, quick results, and can improve the driving safety of urban bridges across rivers.
