Description

Technical Field

[0002] Highway tunnels play an extremely important role in modern transportation networks. They can greatly shorten driving journeys and promote regional connectivity. With the development of highway construction, the number and length of tunnels are increasing. However, many research data show that as the length of highway tunnels increases, the vehicle accident rate also increases.

[0003] Because the driving environment in long highway tunnels is more monotonous and dim, and compared with roads and bridges, the circular curve radius of long highway tunnels is larger, the operation of drivers in long highway tunnels is simple. Drivers are more likely to suffer from visual fatigue during long-term driving, and their perception of changes in traffic flow around the vehicle and their ability to control the vehicle will also be reduced, which will eventually lead to driving safety problems.

[0004] Although existing highway tunnel design solutions include solutions to improve driver visual fatigue through lighting and LEDs, these solutions are not very effective in reducing vehicle accident rates. Therefore, how to reduce the vehicle accident rate in long highway tunnels through tunnel design has become a technical problem that needs to be solved urgently. Summary of the invention

[0007] In a possible implementation manner, each of the second tunnel segments and each of the third tunnel segments are independently arranged between two of the first tunnel segments, and the second tunnel segments and the third tunnel segments are staggered.

[0008] In a possible implementation manner, the length relationship between the first tunnel segment, the second tunnel segment, and the third tunnel segment is: first tunnel segment>second tunnel segment>third tunnel segment.

[0009] In a possible implementation, the number of divisions of the second tunnel segment is one more than the number of divisions of the third tunnel segment, and the number of divisions of the first tunnel segment is one more than the sum of the number of divisions of the second tunnel segment and the number of divisions of the third tunnel segment.

[0010] In a possible implementation manner, the number of divisions of the first tunnel segment is determined based on the length of the target tunnel and a tunnel length threshold, and the number of divisions of the first tunnel segment is an even number.

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0020] In the description of the present invention, reference to an "embodiment" means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the described embodiments may be combined with other embodiments.

[0021] Highway tunnels play an extremely important role in modern transportation networks. They can greatly shorten driving journeys and promote regional connectivity. With the development of highway construction, the number and length of tunnels are increasing. However, many research data show that as the length of highway tunnels increases, the vehicle accident rate also increases.

[0022] Because the driving environment in long highway tunnels is more monotonous and dim, and compared with roads and bridges, the circular curve radius of long highway tunnels is larger, the operation of drivers in long highway tunnels is simple. Drivers are more likely to suffer from visual fatigue during long-term driving, and their perception of changes in traffic flow around the vehicle and their ability to control the vehicle will also be reduced, which will eventually lead to driving safety problems.

[0023] Although existing highway tunnel design solutions include solutions to improve driver visual fatigue through lighting and LEDs, these solutions are not significantly effective in reducing vehicle accident rates.

[0024] In order to solve the above problems, the present invention provides a segmented design method for a long highway tunnel.

[0025] The specific embodiments are described in detail below: A specific embodiment of the present invention discloses a segmented design method for a long highway tunnel, combining Figure 1 Come and see, Figure 1 A schematic flow chart of an embodiment of a segmented design method for a long highway tunnel provided by the present invention includes step S101, wherein: start.

[0026] In step S101, based on the length of the target tunnel, the target tunnel is divided into a plurality of first tunnel segments, a plurality of second tunnel segments, and a plurality of third tunnel segments; The second tunnel section is provided with a light effect for waking up the driver, and the third tunnel section is provided with a painting spray and light effect for simulating a natural landscape.

[0027] Finish.

[0028] During implementation, the target tunnel may be divided into a plurality of first tunnel sections, a plurality of second tunnel sections and a plurality of third tunnel sections according to the length of the target tunnel (generally greater than 10 km).

[0029] The first tunnel section is a conventional tunnel and no additional design is required.

[0030] Light effects for waking up the driver can be provided in the second tunnel section, such as lamps in a dot, line, ring or other shapes, so as to relieve the visual fatigue of the driver.

[0031] In the third tunnel section, the scene of driving out of the tunnel can be simulated by spraying paintings and lighting effects that simulate natural landscapes, further alleviating the visual fatigue of drivers.

[0032] Compared with the prior art, the segmented design method for a long highway tunnel provided in this embodiment divides the long highway tunnel into multiple sub-segments through segmented design, and simulates the scene of driving out of the tunnel through painted spraying and lighting effects simulating natural landscapes, so as to relieve the visual fatigue of drivers caused by long-term driving in the tunnel, thereby reducing the probability of traffic accidents. The present invention relieves the driving fatigue of drivers in long tunnels at a relatively low cost, and can effectively reduce the probability of traffic accidents.

[0033] Exemplarily, each of the second tunnel segments and each of the third tunnel segments are independently arranged between two of the first tunnel segments, and the second tunnel segments and the third tunnel segments are staggered.

[0034] Specifically, when performing segmented design, each second tunnel segment and each third tunnel segment can be independently arranged between two first tunnel segments, and the second tunnel segment and the third tunnel segment need to be staggered. For example, when performing segmented design, the first tunnel segment 1, the second tunnel segment 1, the first tunnel segment 2, the third tunnel segment 1, the first tunnel segment 3, the second tunnel segment 2 can be staggered. White side wall painting and strip waistline can also be set in the second tunnel segment to further relieve the visual fatigue of the driver.

[0035] Exemplarily, the length relationship between the first tunnel section, the second tunnel section and the third tunnel section is: first tunnel section>second tunnel section>third tunnel section.

[0036] Specifically, when performing segmented design, the length of the first tunnel segment>the length of the second tunnel segment>the length of the third tunnel segment. For example, the length of the first tunnel segment can be set to 2 km, the length of the second tunnel segment can be set to 1 km, and the length of the third tunnel segment can be set to 170 m.

[0037] Exemplarily, the number of divisions of the second tunnel segment is one more than the number of divisions of the third tunnel segment, and the number of divisions of the first tunnel segment is one more than the sum of the number of divisions of the second tunnel segment and the number of divisions of the third tunnel segment.

[0038] Specifically, when performing segmentation design, the number of divisions of the second tunnel segment needs to be 1 more than the number of divisions of the third tunnel segment, and the number of divisions of the first tunnel segment needs to be 1 more than the sum of the number of divisions of the second tunnel segment and the number of divisions of the third tunnel segment. For example, when performing segmentation design, 8 first tunnel segments, 4 second tunnel segments, and 3 third tunnel segments may be set.

[0039] Exemplarily, the number of divisions of the first tunnel segment is determined based on the length of the target tunnel and a tunnel length threshold, and the number of divisions of the first tunnel segment is an even number.

[0040] Specifically, the number of divisions of the first tunnel segment can be determined according to the length of the target tunnel and the tunnel length threshold. The tunnel length threshold can be determined according to the relationship between the tunnel length and the vehicle accident rate. Generally, the tunnel length threshold can be set to 3 km, thereby effectively reducing the vehicle accident rate. For example, if the target tunnel is 20 km long, the number of divisions of the first tunnel segment can be determined to be 6.

[0041] The technical solution of the present invention is better described below with reference to a specific embodiment: Combination Figure 2 Come and see, Figure 2The schematic diagram of the first embodiment of the segmented design scene of a long highway tunnel provided by the present invention is that the core landscape section (i.e., the third tunnel section) can be designed in conjunction with the tunnel traffic transfer zone, and decorated with painted spray and new coating materials to create a natural and realistic driving scene outside the tunnel. At the same time, the two sides of the traffic transfer zone are widened by 3m respectively, providing a spatial advantage for simulating a spacious and bright effect outside the tunnel. Considering that the side wall is easily polluted, which will affect the long-term effect of the landscape design, a new coating material with strong durability and easy cleaning can be used within a height range of 1.5m above the maintenance road. The new coating material has advantages in improving the brightness inside the tunnel, thereby reducing lighting energy consumption. The top of the tunnel is painted with spray, and the pattern of the painted spray is mainly natural scenery. The driver can maintain the best driving speed and driving behavior under the decoration of the natural landscape. The natural landscape pattern is mainly blue, green and other receding colors. The receding color can give people the feeling that the side wall is expanding outward, making the tunnel more open. Using the core landscape section can alleviate the psychological burden caused by long-term driving in the tunnel.

[0042] The auxiliary landscape section (i.e. the second tunnel section) uses low-cost visual reference systems such as points, line segments, and rings, and uses active lighting to stimulate human vision. At the same time, long-distance layout can provide drivers with long-distance visual references and alleviate the "tunnel vision" caused during driving.

[0043] The core landscape mainly presents realistic natural scenery, presenting the driving scene outside the tunnel to the driver, and the painted spray can present the landscape effect more realistically. In addition, with the help of new coating materials to improve the brightness inside the tunnel, the high energy consumption caused by blindly strengthening lighting can be reduced. The short-distance landscape effect may not be able to effectively play the fatigue awakening function, so an auxiliary landscape section is added. The auxiliary landscape section uses low-energy light sources and longer distance layout to further play the fatigue awakening function.

[0044] The present invention changes the monotonous and dim tunnel driving environment by means of landscape design, and relieves the visual fatigue of the driver through the changeable and rhythmic visual stimulation.

[0045] The embodiment of the present invention also provides a segmented design device for a long highway tunnel, Figure 3 Come and see, Figure 3 The schematic diagram of the structure of an embodiment of a segmented design device for a long highway tunnel provided by the present invention is as follows. The segmented design device 300 for a long highway tunnel comprises: A segmentation module 301, configured to divide the target tunnel into a plurality of first tunnel segments, a plurality of second tunnel segments, and a plurality of third tunnel segments based on the length of the target tunnel; The second tunnel section is provided with a light effect for waking up the driver, and the third tunnel section is provided with a painting spray and light effect for simulating a natural landscape.

[0046] The specific implementation methods of each module of the segmented design device for a long highway tunnel can refer to the description of the segmented design method for a long highway tunnel mentioned above, and have similar beneficial effects, which will not be repeated here.

[0047] The present invention discloses a segmented design method and device for a long highway tunnel. The long highway tunnel is divided into a plurality of sub-segments through segmented design, and the scene of driving out of the tunnel is simulated by spraying and lighting effects simulating natural landscapes, so as to relieve the visual fatigue of drivers caused by long-term driving in the tunnel, thereby reducing the probability of traffic accidents. The present invention relieves the driving fatigue of drivers in long tunnels at a relatively low cost, and can effectively reduce the probability of traffic accidents.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
