Description

Technical Field

[0001] The present invention relates to the technical field of sight guidance for tunnel entrances, and more specifically, to an adaptive light-shielding shed and a multi-dimensional rhythm induction system for a submarine tunnel entrance. Background Art

[0002] As a driving environment mutation area, the entrance of a submarine tunnel has long faced safety hazards such as poor light environment adaptability and lack of multi-dimensional perception. Traditional light-shielding facilities mostly adopt fixed structures and single light-transmitting materials, having problems such as insufficient light intensity adjustment ability and low glare suppression efficiency, and it is difficult to meet the dynamic requirements under day-night alternation and bad weather. Static induction systems generally rely on basic reflective road markings and contour lights, and the visibility drops sharply in rainy and foggy weather, and there is a lack of a multi-sensory cooperation mechanism, resulting in drivers' difficulty in accurately perceiving the road right boundary and speed changes. Existing acoustic environment regulation means are limited to passive sound-absorbing materials, and the high-frequency traffic noise and warning sounds are seriously mixed, and the key information recognition rate is insufficient. Research shows that the physiological adaptation process of the human eye to the huge change in light intensity inside and outside the tunnel is extremely likely to cause transient visual disability, and the traditional light-shielding structure can only provide linear light intensity attenuation, increasing the pupil adjustment load. In addition, the existing technology lags behind in response to dynamic traffic conditions, unable to achieve real-time matching of the light environment and traffic flow parameters, and lacks cross-dimensional rhythmic guidance design, resulting in increased driver cognitive load and delayed behavior correction. How to construct an intelligent induction system with multi-modal cooperation of light-sound-touch has become the core challenge to break through the safety bottleneck of tunnel entrances.

[0003] Traditional submarine tunnel entrances cause the "black hole / white hole effect" due to the drastic mutation of the light environment, resulting in drivers' transient visual disability, speed perception deviation and direction judgment error, significantly increasing the risk of traffic accidents. The light transmittance of the static light-shielding shed is fixed and cannot adapt to day-night alternation and weather changes. Local overbrightness or overdarkness under extreme light conditions aggravates visual fatigue; the light-transmitting material is single, lacking color temperature adjustment and light direction control, with insufficient glare suppression ability, and the light intensity gradient attenuation is unnatural, prolonging the pupil adaptation period. The acoustic environment is complex, and the passive noise reduction material has low suppression efficiency for vehicle noise frequency bands, the signal-to-noise ratio of key warning sounds is insufficient, and environmental noise interferes with driving attention. The existing induction system relies on a single visual prompt, the ground markings are ineffective in reflecting light in rainy and foggy weather, and the static contour lights cannot dynamically match the vehicle speed or traffic flow density, weakening the induction effect. The lack of multi-dimensional sensory guidance and the failure of auditory warning and tactile feedback to cooperate result in low driver information acquisition efficiency.

[0004] Traditional facilities lack the ability to perceive dynamic environments, unable to respond in real time to fluctuations in traffic flow, changes in visibility, and abnormal events. The preset mode is out of touch with real-time road conditions, and the induction system fails during extreme weather or emergencies. The structural design of the sunshade ignores the corrosion characteristics of the marine environment. Salt spray adhesion accelerates material aging, and maintenance costs are high. The modularity is low, and the replacement of key components such as ETFE air cushions is time-consuming, affecting system availability. Energy supply depends on external power supply, and the ability to operate with low carbon is insufficient. Traditional reflective road studs consume high energy and have poor rain and fog penetration.

[0005] In addition, the sense of depression in the tunnel entrance space intensifies driving anxiety. The static light and shadow lack rhythmic beauty, and the monotonous visual reference objects lead to distraction of attention. The lack of intuitive prompts for slope changes causes improper speed control due to misjudgment of the sense of depth. The detection of abnormal parked vehicles or pedestrians is delayed, and the secondary accident warning mechanism is imperfect. Existing systems have significant deficiencies in aspects such as cross-sensory collaboration, balance of physiological and psychological loads, and full-life cycle efficiency, making it difficult to meet the requirements of safe and efficient passage in modern undersea tunnels. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an adaptive sunshade and multi-dimensional rhythmic induction system for the undersea tunnel entrance.

[0020] The yellow and black facade marked concrete guardrail is arranged at the junction of the tunnel floor and the tunnel sidewall, and the yellow and black facade marked concrete guardrail is arranged from the entrance of the undersea tunnel to the entrance of the undersea tunnel; the height of the yellow and black facade marked concrete guardrail is 1.5 m.

[0021] The lower end of the urban carving texture sidewall is arranged at the upper end of the yellow and black facade marked concrete guardrail. The urban carving texture sidewall is integrated with the yellow and black facade marked concrete guardrail. The urban carving texture sidewall is arranged from the entrance of the undersea tunnel to the entrance of the undersea tunnel. The urban carving texture sidewall gradually decreases as the undersea tunnel goes deeper, and the height of the urban carving texture sidewall gradually changes from 1 m to 0.5 m.

[0022] According to the above scheme, the road surface induction device includes a wave pattern ground navigation line, a transverse self-luminous deceleration belt device, and an energy storage self-luminous road stud device; the wave pattern ground navigation line is longitudinally arranged at the edges of the two side markings of the left lane, the middle lane, and the right lane.

[0023] According to the above solution, the horizontal self-luminous speed bump device includes a first horizontal self-luminous speed bump and a second horizontal self-luminous speed bump; the first horizontal self-luminous speed bump includes two groups. The first group of the first horizontal self-luminous speed bumps are horizontally arranged on the ground 100 m away from the starting point of the light-shielding shed, and the second group of the first horizontal self-luminous speed bumps are arranged at 50 m from the starting point of the light-shielding shed; the second horizontal self-luminous speed bump includes multiple groups, and each group of the second horizontal self-luminous speed bumps are horizontally arranged on the ground of the submarine tunnel where the acrylic light guide column is located; both the first horizontal self-luminous speed bump and the second horizontal self-luminous speed bump include two horizontally arranged self-luminous speed bumps with a spacing of 0.3 - 0.4 m and parallel to each other, and the width of each horizontal self-luminous speed bump is 0.3 - 0.4 m.

[0024] According to the above solution, the energy storage self-luminous road stud device is arranged on the side walls on both sides extending from 50 m in front of the entrance of the submarine tunnel to the end of the submarine tunnel. The energy storage self-luminous road stud device includes two energy storage self-luminous road studs; the energy storage self-luminous road stud device arranged on the left is longitudinally arranged between the side wall of the submarine tunnel and the left marking line of the left lane.

[0025] According to the above solution, the multi-modal perception device includes a spectral analyzer, an illuminance sensor, a millimeter wave radar, a thermal imager, a wind speed and air pressure sensor, a visibility sensor, a temperature and humidity sensor, and a piezoelectric sensor / RFID tag;

[0026] The spectral analyzer includes two, which are respectively arranged on both sides of the entrance of the submarine tunnel; the spectral analyzer is used to analyze the frequency of the side wall light rail belt line and adjust the color temperature of the side wall light rail belt line and the longitudinal light rail;

[0027] The illuminance sensor is arranged on the right side of the submarine tunnel and 3 - 4 m above the ground. The illuminance sensor includes two, which are respectively arranged 30 m in front of and 30 m behind the acrylic light guide column; the illuminance sensor is used to adjust the light rail brightness of the side wall light valley belt line and the longitudinal light rail;

[0028] The millimeter-wave radar is installed on the left side of the undersea tunnel, 30 meters away from the entrance of the undersea tunnel.

[0029] The thermal imager is installed on the side of the acrylic light guide column and at a height of 1 - 1.3 meters from the undersea tunnel. The thermal imager is used to detect whether there are pedestrians accidentally entering or malfunctioning vehicles in the entrance section of the undersea tunnel.

[0030] The wind speed and air pressure sensor is installed at the highest point of the front end of the light-shielding shed.

[0033] According to the above solution, the piezoelectric sensor is used to detect whether a vehicle has entered, and at the same time detect abnormal events such as sudden stops, reverse driving, or collisions of vehicles. The RFID tag is used to transmit audio trigger instructions to individual vehicles to enhance the driver's perception of speed and position through audio.

[0034] Implementing the adaptive light-shielding shed and multi-dimensional rhythm induction system at the entrance of the undersea tunnel of the present invention has the following beneficial effects:

[0035] 1. The present invention can strengthen spatial road rights, and multi-dimensionally guide to improve the accuracy of driving space perception. The sidewall light rail belt line, contour lights, and ground navigation lines work together to form a "sidewall - road surface" multi-level boundary prompt system, realizing the precise definition of lateral road rights. The modular frame spacing decreases, and the height of the bionic optical rhythm light-shielding shed surface from the ground decreases to form a visual "acceleration and gradual contraction" effect. Combining the light and shadow projection of the composite light-transmitting mirror and the combined lights strengthens the longitudinal road right perception. The inclination angle of the seagrass stripes of the acrylic light guide column array dynamically adjusts with the slope, shortening the slope recognition response time and enhancing the slope space perception.

[0036] 2. The present invention can optimize human factors design, synergistically reduce physiological and psychological loads, significantly weaken visual load, and enable the composite light-transmitting system (ETFE air pillow - electrochromic glass - microprism) to achieve smooth transition of combined illuminance from the outside of the tunnel to the inside of the tunnel for "road surface - sidewall - top", with the color temperature dynamically matching the natural spectrum, thus alleviating visual fatigue. Auditory information is efficiently transmitted, the honeycomb-shaped Helmholtz resonance array actively reduces noise, improves the signal-to-noise ratio of key warning sounds, the music road surface melody enhances the driver's attention concentration, and warns the driver to regulate the vehicle speed. The cognition and interaction meet the driver's psychological expectations. The overall multi-dimensional rhythm induction system constructs an immersive visual environment and reduces the psychological pressure brought by the driver's approaching the enclosed space of the tunnel;

[0037] 3. The present invention adapts to dynamic environments, and the multi-modal perception optimizes the induction efficiency in real time. The light intensity gradient is intelligently regulated. Based on the multi-modal perception network (illuminance, spectrum, traffic flow data), the transmittance of the ETFE air pillow, the color temperature of the electrochromic glass, and the deflection angle of the microprism are linked in real time to achieve dynamic adaptation of the light intensity gradient under different weather conditions. The multi-dimensional vehicle speed self-correction mechanism enables the music road surface to be linked with the in-vehicle OBU through RFID tags. When the vehicle speed deviation exceeds ±15%, the scale breaks are triggered. Combined with the high-frequency flashing of the ground energy storage road studs, the brightness and flow rate changes of the light rail, the response time for forcing the driver to adjust the vehicle speed is shortened;

[0038] 4. The present invention can integrate the facility efficiency, optimize the life-cycle cost and reliability, achieve energy self-sufficiency and low-carbon operation. The curved surface of the sunshade is integrated with a solar energy conversion device, which can meet more than 80% of the power demand of the system; the energy storage self-luminous road studs can achieve zero energy consumption for basic night guidance. The module maintenance is convenient. The ETFE air pillow and the modular frame adopt a quick-release structure, greatly shortening the maintenance time;

[0039] 5. The present invention can optimize the tunnel warning function, identify risks in real time and enhance early warning. Abnormal targets are detected in real time. Through the linkage of the thermal imager and the millimeter-wave radar, abnormal targets such as low-speed pedestrians and broken-down vehicles in each lane are accurately identified. The system automatically triggers the red flashing warning of the sidewall light rail belt line, the top combined lights, the full red of the ground navigation line, and the low-frequency alarm (80Hz, 80dB) of the music road surface, reducing the risk of vehicle collisions in the abnormal lane. The visibility is dynamically compensated. The paired visibility sensors continuously monitor the fog concentration. When the visibility < 100m, the luminous intensity of the energy storage road studs, the brightness of the light rail, and the brightness of the combined lights are adaptively enhanced to extend the induction visual distance and make up for the visual defects of manual driving.

[0057] 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 with reference to the accompanying drawings.

[0058] As Figures 1-15 shown, in the adaptive light-shielding shed and multi-dimensional rhythm induction system at the entrance of the undersea tunnel of the present invention, it includes an integrated light-shielding shed and a ceiling. The light-shielding shed is arranged at the entrance of the undersea tunnel, and the ceiling is arranged at the top of the undersea tunnel. There are a left lane, a middle lane, and a right lane in the undersea tunnel. It also includes an upper optical rhythm light-shielding shed induction device, a middle and lower sidewall dynamic rhythm device, a road surface induction device, and a multi-modal perception device; the upper optical rhythm light-shielding shed induction device is arranged on the light-shielding shed and extends to the ceiling, the middle and lower sidewall dynamic rhythm device is arranged on the sidewalls at the front end of the undersea tunnel entrance and extends to the sidewalls inside the undersea tunnel, the road surface induction device is arranged on the ground at the front end of the undersea tunnel entrance and extends to the ground of the undersea tunnel, and the multi-modal perception device is arranged on the ground at the entrance of the undersea tunnel.

[0059] In a preferred embodiment of the present invention, the light-shielding shed includes a modular frame and an involute composite curved surface shell 14. The modular frame is clamped at the entrance of the undersea tunnel, and the involute composite curved surface shell 14 is fixedly arranged inside the modular frame. The modular frame is a detachable quick-release structure, which is composed of a lightweight titanium alloy truss and is arranged at a decreasing rate of 5%-8% in the longitudinal spacing to form a visual "deceleration and gradual contraction" effect. A pressure sensor is embedded in the frame to detect the structural stress in real time, and an anti-glare coating is applied on the surface of the truss. The surface of the involute composite curved surface shell 14 is coated with a silica self-cleaning coating (contact angle ≥ 150°) to reduce the attachment of marine salt spray. The thickness gradually decreases from the entrance to the inside of the tunnel along the driving direction to form a natural light intensity attenuation. The inner surface of the shell presents a wave pattern. As the distance from the tunnel entrance gets closer, the distance from the top of the wave to the ground gradually becomes smaller, indicating that the closed tunnel section is about to be entered, which conforms to the psychological expectation of the driver. The front end of the shell tilts upward at an elevation angle of 12-15° to block direct sunlight and reduce disability glare.

[0060] In a preferred embodiment of the present invention, the upper optical rhythm shading shed induction device includes a composite light-transmitting mirror 1, a longitudinal light rail 2, a transverse reflective ring 3, a Helmholtz resonance sound absorption array 4, and a contour light rail 5.

[0061] The composite light-transmitting mirror 1 is snap-fitted on the involute composite curved surface housing 14. The composite light-transmitting mirror 1 is elliptical and its major axis is parallel to the undersea tunnel. There are three composite light-transmitting mirrors 1 arranged horizontally, and their major axes are respectively located above the center lines of the left lane, the middle lane, and the right lane. The composite light-transmitting mirror 1 gradually shrinks longitudinally as the tunnel deepens. The length of the major axis of the composite light-transmitting mirror 1 gradually changes from 16 m to 8 m, and the length of the minor axis gradually changes from 2 m to 1 m. The distance between adjacent composite light-transmitting mirrors 1 is 15 m. The interval of the hollow areas of the composite light-transmitting mirror 1 corresponds to the distance at a standard vehicle speed of 0.5 s - 1.5 s, and the interval gradually decreases as the travel distance increases, enhancing the driver's "acceleration feeling", and thus achieving the purpose of regulating the driver's vehicle speed. The composite light-transmitting mirror 1 group adopts a three-layer composite structure of ETFE air pillow - electrochromic glass - microprism array. The thickness of the outer ETFE air pillow is 20 mm, and the light transmittance is dynamically adjusted by the inflation pressure, with a light transmittance of 40% - 90%, supporting curved surface deformation. The middle layer of electrochromic glass is based on a WO3 thin film (thickness 70 nm), with a response time ≤ 1.2 s, a light transmittance adjustment range of 5% - 80%, and a color temperature adjustable range of 3000 K - 6500 K. The size of the inner prism unit is 1 mm × 1 mm, and the deflection angle is adjustable from 0° to 45°. Through the composite light-transmitting mirror 1, the full utilization of sunlight can be achieved. In the light concentration mode, the shading shed takes enhancing induction as the main goal and optical smooth transition as the auxiliary. Through the directional brightening of sunlight, the enhancement effects on the road surface, the light rail belt line, and the acrylic light guide column 6 are achieved. The driver can easily identify the lane and the side wall, enhancing the driver's perception of lateral and longitudinal road rights. Through the light and dark light and shadow effects formed by sunlight, light and shadow vertical stripes are generated on the side wall, enhancing the driver's ability to maintain the vehicle distance. In the smooth transition mode, the shading shed takes optical smooth transition as the main goal, achieving the combined smooth transition effect of the optical illuminance of the "road surface - side wall - top" from outside the tunnel to inside the tunnel, greatly alleviating adverse glare, stroboscopic effects, and zebra effects.

[0062] There are eight longitudinal light rails 2, which are longitudinally and evenly arranged on the involute composite curved surface housing and extend to the ceiling. The longitudinal light rail 2 is trapezoidal. The starting point of the longitudinal light rail 2 is set at the edge of the involute composite curved surface housing, and the end point of the longitudinal light rail 2 extends to the end of the undersea tunnel. The longitudinal light rail 2 is trapezoidal, with the upper base width of the trapezoid being 0.2 m, the lower base width of the trapezoid being 0.4 m. The lower base of the trapezoid is set at the edge of the involute composite curved surface housing, and the upper base of the trapezoid is set at the end of the undersea tunnel. The longitudinal light rail 2 gradually narrows as the tunnel deepens.

[0063] There are multiple horizontal reflective rings 3, which are evenly arranged horizontally on the open-line composite curved surface housing 14 and extend to the ceiling. The first horizontal reflective ring 3 is set at a position 120 m away from the entrance of the undersea tunnel. The distance between adjacent horizontal reflective rings 3 is 25 m. The horizontal reflective rings 3 are rectangular, and the width of adjacent horizontal reflective rings 3 gradually decreases as the tunnel extends. The width of the horizontal reflective ring 3 gradually changes from 0.6 m to 0.3 m.

[0064] The Helmholtz resonance absorption array 4 is laid flat between adjacent longitudinal light rails 2. Each unit in the Helmholtz resonance absorption array 4 adopts a hexagonal honeycomb design with a side length of 80 mm and an internal resonance cavity (cavity depth 40 mm). The sound absorption coefficient α≥0.85 (frequency range 100 - 5000 Hz). When the background noise exceeds 65 dB, the frequency shift of the Helmholtz resonance absorption array 4 is activated, which can filter the vehicle noise in the tunnel to a great extent, retain the warning voice in the tunnel and the effective driving auditory information provided by the music road surface, and improve the driver's auditory feedback ability.

[0065] The contour light rail 5 is set on the ceiling. The contour light rail 5 is a U-shaped light rail. The U-shaped vertex of the contour light rail 5 is set at the starting point of the undersea tunnel, and the U-shaped bottom point of the contour light rail 5 is set at the key point of the undersea tunnel at any time.

[0066] In the preferred embodiment of the present invention, the middle and lower sidewall dynamic rhythm device includes acrylic light guide columns 6, sidewall lighting fixtures 7, sidewall light rail belt lines 8, yellow and black facade marked concrete guardrails 9, and urban carved texture sidewalls 13. There are multiple acrylic light guide columns 6, which are evenly arranged at an interval of 25 m. The set length of the acrylic light guide columns 6 extends from a position 120 m away from the entrance of the undersea tunnel to the end of the undersea tunnel. The outer layer of the acrylic light guide column 6 is holographic image glass with a diameter of 400 mm, and the interval is the standard vehicle speed travel of 1 s - 1.5 s. It is alternately arranged corresponding to the hollow of the bionic optical rhythm shading shed. The image is a holographic seagrass stripe, and the inclination angle changes with the slope. For every 1° increase in the slope, the inclination angle increases by 5°, which strengthens the driver's slope perception ability.

The energy storage self-luminous road stud 12 uses rare earth aluminate energy storage materials, with a hemispherical lens covering the surface, a luminous intensity ≥ 300 mcd, and a spacing of 0.5 - 1.5 m, forming a visual acceleration effect to standardize the driving speed.

[0072] In the preferred embodiment of the present invention, the multi-modal perception device includes a spectral analyzer 16, an illuminance sensor 18, a millimeter wave radar 19, an infrared thermal imager 17, a wind speed and air pressure sensor 15, a visibility sensor 20, and a piezoelectric sensor / RFID tag 22.

[0073] The spectral analyzer 16 includes two, which are respectively arranged on both sides at the entrance of the submarine tunnel; the spectral analyzer 16 is used to analyze the frequency of the side wall light rail belt line 8, and adjust the color temperature of the side wall light rail belt line 8 and the longitudinal light rail 2; realizing the dynamic matching of the natural light spectrum components to the color temperature adjustment curve of the electrochromic glass to relieve visual fatigue.

[0074] The illuminance sensor 18 is installed on the right side of the undersea tunnel, 3-4 meters above the ground. There are two illuminance sensors 18, which are respectively installed 30 meters in front of and 30 meters behind the acrylic light guide column 6. The illuminance sensor 18 is used to adjust the light rail brightness of the sidewall optical valley belt line and the longitudinal light rail 2, and to detect the changes in the illumination intensity of the "road surface - sidewall - top" of the tunnel inside and outside in real time, providing a data benchmark for the adaptive dimming of the composite light-transmitting mirror 1 and the combined light brightness.

[0075] The millimeter-wave radar 19 is installed on the left side of the undersea tunnel, 30 meters away from the entrance of the undersea tunnel. The millimeter-wave radar 19 is installed 1-1.3 meters above the ground of the undersea tunnel. The millimeter-wave radar 19 is used to detect the vehicle speed of the passing vehicles; accurately detect the vehicle speed and traffic volume.

[0076] The thermal imager 17 is installed on the side of the acrylic light guide column 6, 1-1.3 meters away from the height of the undersea tunnel. The thermal imager 17 is used to detect whether there are pedestrians accidentally entering the entrance section of the undersea tunnel and whether there are faulty vehicles; identify abnormal targets such as low-speed pedestrians and broken-down vehicles.

[0077] The wind speed and air pressure sensor 15 is installed at the highest point of the front end of the light-shielding shed. The wind speed and air pressure sensor 15 is used to detect the environmental wind speed and air pressure, and adjust the air pressure of the composite light-transmitting mirror 1 to ensure the structural strength of the composite light-transmitting mirror 1;

[0078] The visibility sensor 20 is installed 20-30 meters from the starting point of the light-shielding shed. The visibility sensor 20 is used to detect foggy weather and judge the visibility of the driver. The optical path passes horizontally through the lane, and the tunnel visibility, fog concentration, and particulate matter mass concentration are detected in real time.

[0079] The temperature and humidity sensor 21 is centrally arranged at the highest point of the bionic optical rhythm light-shielding shed to correct the performance of the composite light-transmitting mirror 1 in real time. The pressure sensor is integrated at the inflation pipeline node inside the ETFE air pillow to dynamically adjust the inside of the ETFE air pillow, maintain the stability of the curved surface shape, and give a real-time warning of over-limit structural stress.

[0080] The piezoelectric sensor / RFID tag 22 is installed under the road surface base layer at the starting point of the light-shielding shed. The piezoelectric sensor is used to detect whether a vehicle has entered. The RFID tag is used to send music signals to individual vehicles, and the driver can receive the music signals through the radio. RFID tags are arranged in three lanes, namely the left lane, the middle lane, and the right lane, to communicate with the in-vehicle OBU. When the vehicle speed deviation exceeds ±15%, the scale breaks, that is, the fundamental frequency deviation amount ≥ 50Hz, and a low-frequency warning sound with a frequency of 80Hz and a sound pressure level of 75dB is triggered. A device that converts solar energy into electrical energy and stores electrical energy is installed on the outer surface of the light-shielding shed to supply power to the lighting devices in the induction system.

[0081] In the preferred embodiment of the present invention, based on the spatial positions of "high, middle, low" and the rhythm types of "continuous repetition, interleaving, gradual change, undulation", the visual rhythm design is classified into a high-position top main body, a middle-position sidewall main body, and a low-position (road surface main body), specifically as follows:

[0082] The high-position top main body is as follows. For continuous repetition: modular frameworks are arranged at a decreasing rate of 5% - 8% in the longitudinal spacing, forming a visual "deceleration and gradual contraction" effect, suggesting that the driver adjusts the vehicle speed. A honeycomb light curtain projects starry sky or ocean wave scenes on the top, and the periodic repetition strengthens the skyline guidance. For gradual change: a composite light-transmitting lens 1 of ETFE air pillow - electrochromic glass - microprism, such that the light transmittance gradually decreases longitudinally along the tunnel entrance, realizing a smooth transition of brightness. For undulation: the top light combination dynamically adjusts the brightness and angle (such as linear lights, surface lights, light rails), responding to traffic flow and weather changes, forming a rhythmic fluctuation.

[0083] The middle-position sidewall main body is as follows. For interleaving: the light rail belt line has five independent light rails with alternating colors and brightness, strengthening the sidewall boundary sense. The inclination angle of the acrylic light guide column 6 array seaweed stripes is dynamically adjusted according to the slope. For every 1° increase in the slope, the inclination angle increases by 7°, and it is alternately arranged with the cutouts of the sunshade shed. For gradual change: the backlight color temperature of the sidewall laser-etched curtain wall gradually changes between day and night, coordinating with the natural light transition design. For undulation: the brightness of the linear contour lights is dynamically adjusted, responding to the vehicle speed or abnormal time, and changing with different modes.

[0084] The low-position (road surface main body) is as follows. For continuous repetition: the energy storage self-luminous road studs 12 are spaced 0.5 - 1.5 m apart, and the high-frequency flashing prompts the lane boundary, forming a visual acceleration effect. The ground navigation line dynamically switches colors (such as blue and green), guiding the lane selection. For gradual change: when the vehicle speed deviation occurs on the music road surface, the scale breaks (the fundamental frequency deviation ≥ 50 Hz), and the gradual change of the musical interval gives a warning. For undulation: the light and shadow projection of the ground markings changes with the vehicle distance, and is interrupted by the front obstacle, triggering a deceleration response.

[0085] The continuous repetition rhythm occupies the high / low position space, strengthening the longitudinal road right, standardizing the vehicle speed, improving the lane-keeping stability, and the sense of rhythm reduces the driving anxiety. The gradual change rhythm occupies the high / middle position space, with a smooth brightness transition, reducing glare, shortening the pupil adaptation time, and the combination of different lights and daylight enhances the psychological comfort. The interleaving rhythm occupies the middle position space, clearly defining the lateral road right, preventing lateral collisions, and the dynamic colors relieve the monotony. The undulation rhythm occupies the high / low position space, dynamically responding to traffic events, warning abnormal targets in real time, creating a sense of space through light and shadow art, and enhancing the immersive experience.

[0086] In the preferred embodiment of the present invention, visual and auditory rhythms have advantages in spatial road right perception, human factor optimization, driving task support, and comfort, specifically as follows:

[0087] Vertical Right-of-Way Strengthened by Spatial Right-of-Way: The light rail belt line (mid-position) and the top combined lighting (high-position) form a vertical boundary. Through the height difference (1.6m - 3.0m) and brightness gradient of 5 independent light rails, the sidewall and top spaces are clearly defined. The light intensity transitions from the lower light rail to the upper one, strengthening the visual focus and guiding the driver to maintain a lateral safety distance. In the night mode, the light rail switches to a blue-amber light ratio of 3:7, inhibiting melatonin secretion while maintaining the visibility of the boundary. Horizontal Right-of-Way: The energy-storing self-luminous road studs are spaced 0.5 - 1.5m apart, forming a 3Hz high-frequency flicker, which, combined with the ground markings and road navigation lines, clarifies the lane edges and lane-changing situations. The sidewall contour lights indicate the trend of lateral space compression through brightness grading (bright at the top and dim at the bottom) to prevent vehicle collisions. Longitudinal Right-of-Way: The modular frame has a gradient effect. The frame spacing decreases from 3m at the entrance to 1.5m inside the tunnel, creating a visual "accelerated taper" that implies the driver to slow down. The top light rail and the ground navigation line dynamically adjust the flow speed (such as the green wave band flow speed of 80km / h), and the visual feedback matches the vehicle speed to optimize the longitudinal vehicle distance control.

[0088] Visual Distance Guarantee Optimized by Human Factors: When the visibility is less than 50m in the foggy mode, the light rail belt line switches to high-frequency yellow flashing, penetrating the fog and increasing the visible distance to 150m. The ETFE air pillow - electrochromic glass - microprism composite light-transmitting system dynamically adjusts the light transmittance. Combined with the front elevation angle of the sunshade shed, it enhances the glare suppression effect and reduces pupil contraction fatigue. Visual Area Coverage: The ETFE air pillow - electrochromic glass - microprism composite light-transmitting system directs natural light to key areas, such as enhancing the contrast between the ground markings and the road surface of the lane. Visual Illusion Correction: The intermittent warning of light and shadow projection. When the ground light and shadow are interrupted by a vehicle or obstacle ahead, it triggers the driver to decelerate accordingly. Slope Visual Compensation: The inclination angles of different stripes of the light guide column dynamically adjust with the slope. Through the visual magnification effect, it strengthens the sense of depth of the downhill slope, avoids visual misjudgment, and indirectly prompts downshifting and speed control.

[0089] Vehicle speed control supported by driving tasks: The optical flow rates of the top and sidewall light rails are dynamically adjusted according to the traffic vehicle speed, always keeping consistent with the required vehicle speed in the current scenario. When the vehicle speed deviation is ±15%, the driver can feel a significant relative movement of the light rails, and it triggers the fracture of the music road surface scale (fundamental frequency shift ≥ 50 Hz) and the low-frequency warning sound (80 Hz @ 75 dB), forcing the driver to adjust the vehicle speed. The decreasing modular frame spacing forms a visual "sense of acceleration", inducing the driver to actively reduce the speed to the standard speed (such as 60 km / h). Vehicle distance maintenance: The ground markings provide dynamic feedback. When the vehicle distance < safety threshold, the ground navigation line switches to a gradually changing red-green color, and together with the dynamic effect of the top light rail and the sidewall light guide column array, it clarifies the vehicle distance and optimizes the following distance. If there is an abnormal parking behavior, it triggers the 8 Hz red flashing of the sidewall light rail belt line, synchronizing the low-frequency vibration of the music road surface (40 Hz @ 75 dB), and the multi-modal cooperation enhances the vehicle distance perception. Lane keeping: The road studs flash at a high frequency, combined with the color and brightness effects of the road surface navigation line, reducing the risk of lane departure in rainy and foggy weather. At the same time, the road surface navigation line displays lane change guidance information through blue or green light, further optimizing the rationality of the driver's lane change behavior. The sidewall contour lights clarify the boundary between the road surface and the sidewall, and clarify the distance between the vehicle and the sidewall.

[0090] Facility shape for enhanced facility comfort: The compound surface of hyperbolic paraboloid and involute simulates the sea wave ripples, and the gradual change of the shell thickness reduces the sense of depression in the enclosed space. The inclination angle of the 6 holographic seagrass stripes on the acrylic light guide column changes dynamically, combined with the starry sky scene projected by the top honeycomb light curtain (the star point density gradually increases), creating an immersive experience of the "underwater - starry sky" transition. Facility color: The color temperature is dynamically adapted. The color temperature during the day is 6500K (cool white) to match natural light, and it switches to 3000K (warm yellow) at night, inhibiting the secretion of melatonin (blue light proportion < 30%). At sunset, the color temperature linearly transitions from 6500K to 3000K, synchronizing the human biological clock and alleviating the pupil contraction lag. Light and shadow aesthetic design: Art projection, the compound light transmission system forms the rhythm of the sun's light and shadow, combined with the dynamic projection of the honeycomb light curtain of the starry sky, sea waves and other scenes (wavelength 610 - 630nm), combined with the harmonious melody of the music road surface (BPM = vehicle speed × 3), forming an audio-visual synchronous driving rhythm. Low peak soothing mode, when the late-night traffic flow < 5 veh / h, the top line lights switch to the breathing mode (brightness period 8s), and the music is superimposed with δ waves (0.5 - 4Hz) and white noise to reduce anxiety. Acoustic comfort: Active noise reduction, the sound absorption coefficient α of the honeycomb Helmholtz resonance array is ≥ 0.85 (100 - 5000Hz), the noise attenuation is ≥ 12dB, and the signal-to-noise ratio of the key warning sound is retained > 25dB. Interaction with the music road surface, the standard vehicle speed triggers a harmonious scale (such as the C major scale), and the scale breaks when the speed deviates (fundamental frequency shift ≥ 50Hz), and the vehicle speed adjustment is naturally guided through the "disharmony" of hearing.

[0091] In a preferred embodiment of the present invention, two-dimensional rhythm: cross-sensory fusion—the fusion of vision and hearing. For example, visual feedback from the synchronized speed changes of the top combination lights and sidewall light rails, combined with auditory feedback from changes in road pitch, improves the driver's ability to maintain speed. Dynamic environmental response—the integration of vision and environment, time and vision linkage—changes the transmittance and prism angle of the composite light-transmitting mirror 1 according to changes in scene time, achieving a smooth transition effect of the combined illumination of "road surface, sidewall, and top" during tunnel entry. The honeycomb light curtain of the top combination lights projects natural scenes such as the starry sky and ocean waves, enhancing the visual guidance of the skyline and improving the driver's immersive experience. Weather and vision linkage—dynamically adjusts the visual effect based on weather changes captured by the environmental parameter perception module (temperature, humidity, and visibility sensor 20). For example, in rainy and foggy weather, the brightness of the top combination lights decreases, and the color of the light rail beltline changes to a cool tone to enhance visual guidance. In foggy weather, the frequency of the top combination lights increases, and the brightness of the boundary lights increases, ensuring that the driver can clearly perceive the road-sidewall-top boundary.

[0092] In a preferred embodiment of the present invention, three-dimensional rhythm: multi-sensory synergy—a three-dimensional combination of vision, hearing, and touch. Under visual guidance, the top combined lighting and sidewall light rail beltline 8 provide clear visual boundaries and guide lines, comprehensively improving the driver's perception of driving behavior. Under auditory guidance, the musical road surface prompts the driver to adjust the vehicle speed and driving behavior through dynamic melody and rhythm. Under tactile guidance, road vibration feedback is synchronized with lighting changes, enhancing the driver's perception of speed and slope, especially in adverse weather conditions. The synergistic effect of multiple senses can significantly enhance the driver's perception of the surrounding environment, reducing traffic accidents caused by visual fatigue or insufficient information. The three-dimensional sensory feedback can provide a richer and more immersive driving experience, reduce driving fatigue, and enhance the overall driving experience.

[0093] In a preferred embodiment of the present invention, the following twelve adaptive modes are designed in combination with multi-dimensional parameters of weather, time, and traffic conditions. Based on the three dimensions of safety, response timeliness, and impact range, a four-level priority system is constructed, namely L0 emergency, L1 high risk, L2 routine, and L3 optimization.

[0094] In the preferred embodiments of the present invention, the criteria for determining Level L0 emergencies are directly threatening life safety (fires or major accidents) or requiring right of way (emergency vehicles), and all system resources are prioritized accordingly; the criteria for determining Level L1 high risks are high accident risk environments (dense fog, heavy rain, strong winds) or critical facility failures, and enhanced handling is carried out in local areas; the criteria for determining Level L2 normal are traffic conditions requiring active intervention (congestion, speed deviation) or normal environmental adaptation (day-night alternation, weather changes), and progressive dynamic adjustment is made; the criteria for determining Level L3 energy saving are non-emergency efficiency states (energy saving, low-flow silence). The L0 emergency mode has the following adaptive modes:

[0095] Mode 1: Tunnel fire emergency mode. Explanation: Solve the problem of invisible escape routes and out-of-control panic behavior in high-temperature and thick-smoke environments.

[0096] Trigger conditions: When the temperature detected by thermal imaging > 100°C, CO concentration > 100 ppm, and smoke density > at 5% obs / m. System response: Smoke exhaust and escape guidance. The light transmittance of the ETFE air pillow is 100%, green escape arrows are projected by the top light rail at intervals of 10 m, and the laser curtain wall cooperates with the light rail to display the fire escape direction, using an 850 nm wavelength optical pattern that can penetrate smoke. Acoustic-optical linkage. The acoustic wave broadcast is 2800 Hz @ 90 dB, signal-to-noise ratio > 25 dB, the ground road studs are switched to red and green flashing, and the ground guiding lines are switched to red and green gradient colors, with red being the direction of the fire source and green being the escape direction.

[0097] Priority override: Forcefully interrupt all other modes.

[0098] Mode 2: Priority passage mode for special service vehicles. Explanation: Solve the problems of unclear right of way and low avoidance efficiency of emergency vehicles in mixed traffic, and optimize the lack of lane-level diversion and avoidance in traditional signal priority systems.

[0099] Trigger conditions: RFID identification of emergency vehicle tags + voiceprint matching of siren features or response from the background dispatching system. System response: Lane-level control. Intelligent selection of the lanes that special service vehicles can travel on, and the words "Special service vehicle priority" are projected onto the ground by the lights at the top of the corresponding lanes. The top light rail and the side wall light rail of the corresponding lanes are switched to a green waveband with a flow rate of 80 km / h and a wavelength of 520 nm. Cooperative avoidance, a colored flow barrier is generated on the road surface navigation line of the lane where the special service vehicle travels, and the road surface navigation lines of other lanes are closed.

[0100] Mode 3: Emergency disposal mode for structural failure. Explanation: Prevent the structural collapse of the sunshade caused by typhoons or earthquakes, and make up for the lack of an active pressure relief mechanism in traditional structures.

[0101] Trigger conditions: Modular frame stress > 45 MPa + wind speed > 25 m / s

[0102] System response: Structural protection. The ETFE air pillow is depressurized to 0.01 MPa within 10 s to reduce wind load. Risk warning, the thermal stress distribution heat map of the light projection on the top of the side wall (red area > 30 MPa, yellow area 15 - 30 MPa), the music road surface triggers a low-frequency resonance alarm, using 40 Hz @ 75 dB, warning vehicles to pass through this area quickly. If it reaches 90% of the maximum bearing stress of the frame, full red lights are used to warn vehicles not to enter the tunnel entrance area.

[0103] There are the following adaptive modes in the L1 high-risk mode:

[0104] Mode 4: Enhanced fog penetration mode. Explanation: Overcome the problems of serious light scattering and lack of visual reference objects in thick fog, and replace the traditional fog lights with weak penetration and easy to produce light curtain effect.

[0105] Trigger condition: Visibility sensor < 50 m + humidity > 95% + fog droplet concentration > 1000 / cm 3 System response: Optical enhancement. The light rail belt line switches to high-frequency yellow flashing, with a frequency of 2 Hz, a wavelength of 590 nm, and a brightness of 2000 cd / m 2 . The side wall light projection is a white stripe along the road direction, strengthening the perception of longitudinal road rights and helping the driver to identify the vehicle or other obstacles ahead. Acoustic navigation. The music road surface generates a swept-frequency sound wave, using 200 - 800 Hz, a sound pressure gradient of 5 dB / m, and the Helmholtz array filters 1 kHz noise, improving the signal-to-noise ratio.

[0106] Mode 5: Rainstorm and flood prevention mode

[0107] Explanation: Solve the problems of water surface reflection interference and wading driving risk in rainstorms

[0108] Trigger condition: Rainfall > 50 mm / h + road surface water depth sensor > 15 cm

[0109] System response: Flood prevention guidance. The top light rail and the side wall light rail use a constantly lit blue light band, the side wall bottom contour lights are turned on, the ground navigation line uses an orange demarcation warning, and the luminous road studs use 3 Hz stroboscopic flashing. Acoustic intervention. The music road surface triggers a continuous low-frequency pulse, using 80 Hz @ 85 dB, and the noise reduction array shields the rain noise in the frequency band > 5 kHz.

[0110] Mode 6: Accident warning and vehicle avoidance mode. Explanation: Prevent the vehicle distance from being too close and the braking being untimely in secondary accidents, and make up for the deficiencies of traditional warning signs being static, passive and lacking emergency response.

[0111] Trigger conditions: The millimeter-wave radar 19 detects abnormal parking and the following vehicle distance < safety threshold. System response: Hierarchical warning. Level 1 (vehicle distance > 50m): The top light rail of the abnormal parking lane shows red flashes (2Hz), and there is a gentle reminder sound on the music road surface. Level 2 (vehicle distance ≤ 50m): The top light rail of the abnormal parking lane shows red flashes (4Hz) + a red light band appears on the side wall light rail of this side + the ground + an 80Hz low-frequency sound wave tactile vibration warns the driver.

[0112] There are the following adaptive modes in the L2 normal mode:

[0113] Mode 7: Peak slowdown collaborative guidance mode. Description: Alleviate the driver's anxiety caused by congestion and the out-of-control following distance, and break through the limitations of the traditional induction screen with delayed information update and lack of lane-level management.

[0114] Trigger conditions: Traffic flow density > 80veh / km / lane + lane speed < 15km / h + duration > 5min. System response: Intelligent induction. The light rail shows a blue wave flowing effect, and the flowing speed is consistent with the traffic flow speed. The side wall and the top light-shielding shed project ocean rhythm patterns, creating a relaxed and fun visual environment. The music road surface generates a rhythm audio with BPM = traffic flow speed * 3, making the music rhythm related to the vehicle speed, enhancing the driving immersion, and the rhythm conforms to the driver's expectation, avoiding the analysis and anxiety caused by the sudden change of the rhythm. Lane-level management. The ground navigation line switches to blue and green, with blue being the recommended lane and green being the variable lane. The lane with fewer vehicles in the three lanes is intelligently identified and shown in green.

[0115] Mode 8: Twilight transition mode. Description: Adjust the pupil contraction lag and melatonin secretion disorder during the day-night alternation, and improve the disadvantages of sudden color temperature change and poor physiological adaptability in traditional lighting.

[0116] Trigger conditions: 30 minutes before and after sunset + illuminance change rate > 50lux / min

[0117] System response: Biological adaptation. The color temperature of the top and side wall lights linearly transitions from 6500K to 3000K, matching the human melatonin secretion curve. Utilize the lights to supplement the effect of the composite light-transmitting lens 1 to achieve the "road surface - side wall - top" combined illuminance smooth transition effect of "outside the tunnel - light-shielding shed section - inside the tunnel", and synchronize the pupil contraction speed. Immersive experience, the side wall curtain projects the setting sun afterglow scene, with a wavelength of 610nm - 630nm, alleviating the driver's anxiety.

[0118] Mode 9: Bright noon strong light mode. Description: Make full use of the light and shadow rhythm under strong light conditions, which is the scene in most cases during the day and has the best induction effect during the day.

[0119] Trigger conditions: Light intensity > 100,000 lux + smooth traffic flow (vehicle speed fluctuation < ±10%) + free flow system response: Multidimensional rhythm induction of light and shadow, taking into account speed perception, slope perception, and vehicle distance perception. For speed perception, the light rails on the sidewalls and the top adopt the daytime flowing light speed perception mode. When the vehicle is driving at the standard speed, the musical road surface triggers continuous and harmonious melodies. When the speed deviation exceeds 15%, the intervals break and are accompanied by low-frequency warning sounds, forcing the driver to adjust the vehicle speed. For slope perception, the sidewall contour lights are turned on. From outside the tunnel to inside the tunnel, for every 1° increase in slope, the inclination angle of the acrylic light-transmitting columns increases by 7°. The width of the vertical stripes used gradually thickens from thin to thick. For vehicle distance perception, the ETFE air pillow - electrochromic glass - microprism composite light-transmitting system turns on stepless adaptive light transmission and projects the light and shadow effect onto the road surface, enhancing the contrast between the road surface and the markings, strengthening the driver's perception of road rights. If there are vehicles or obstacles on the road ahead, the driver will find that the light and shadow effect is interrupted and quickly make a response of decelerating and stopping.

[0120] Mode Ten: Nighttime Low-Light Mode Description: Make full use of the rhythm formed by the lights in the sunshade section as the scene in most cases at night, with the best induction effect at night.

[0121] Trigger conditions: Ambient illuminance outside the tunnel < 20 lux + smooth traffic flow (vehicle speed fluctuation < ±10%) + free flow system response: On the basis of ensuring good speed perception, slope perception, and vehicle distance perception and good induction effect, form an immersive driving environment with artistic and beautiful multidimensional rhythm. The difference from Mode Nine is that through the combination of lights, an illuminance joint smooth transition effect is achieved. The light rail uses a blue-amber light ratio of 3:7, the proportion of blue light (450 nm) is < 30% and the peak value avoids 480 nm, inhibiting the excessive secretion of the driver's melatonin. While keeping the driver alert, it avoids the harm of blue light. The starry sky effect is projected on the top, and the density of dynamic star points gradually increases as the vehicle enters the tunnel. The water ripple effect is projected on the sidewall, and the seagrass stripes of the acrylic light-transmitting columns fluctuate slowly, simulating the underwater light and shadow. There are the following adaptive modes for the L3 energy-saving mode: <{

[0122] Mode Eleven: Daytime Low-Energy Consumption Energy-Saving Mode

[0123] Description: Balance the basic induction needs and energy-saving needs during the day

[0124] Trigger conditions: Daytime traffic flow < 20 veh / h / lane (low-peak free flow)

[0125] System response: The light transmittance of the ETFE air pillow is increased to 85% (inflation pressure 0.1 MPa), maximizing the use of natural light. The electrochromic glass switches to the heat insulation mode (infrared reflectance > 90%, visible light transmittance 60%), concentrating sunlight on the road surface. Keep the bottom of the light rail belt line white and always on. The energy storage road studs switch to the daytime energy storage mode. Turn off the non-essential lighting such as the top light rail and the backlights of the side wall curtain wall decorations, and turn off the non-essential acoustic measures such as the music road.

[0126] Mode Twelve: Nighttime Low-Energy Rhythmic Relaxing Mode

[0127] Description: Balance the basic nighttime guiding demand and the energy-saving demand

[0128] Trigger condition: Nighttime traffic flow < 5 veh / h / lane (late-night no-vehicle period)

[0129] System response: The top line lights switch to the low-frequency breathing mode (brightness period 8 s, wavelength 580 nm amber light), only activate light rail belt lines 1 and 5 (top / bottom white and always on, 100 cd / m 2 ), activate the side wall contour lights (white and always on, 50 cd / m 2 ). 2. The light transmittance of the ETFE air pillow is reduced to 20%, the air pillow pressure is 0.05 MPa (minimum energy consumption to maintain the shape), and the power supply of the electrochromic glass is turned off. The music road plays the δ-wave frequency sound effect (0.5 - 4 Hz) superimposed with natural white noise (40 dB). The Helmholtz array filters out noises above 500 Hz (retaining the environmental background noise, noise reduction depth 25 dB), inducing a deep relaxation state and reducing the anxiety in a silent environment.
