A highway nose end night driving safety improving device

Abstract

This utility model discloses a nighttime driving safety enhancement device at the nose of a highway, belonging to the field of highway traffic safety technology. This utility model uses nighttime vision guidance components deployed on the mainline and ramp guardrails in a designated area to continuously guide drivers in anticipating changes in traffic flow, preventing sudden accidents. Illuminated warning components behind the small nose point alert drivers to entering critical areas, while reflective guide components in front help predict road direction. Warm yellow and pure white guidance lights are respectively installed on the left and right sides to help determine road boundaries, with continuous lighting guiding the driver's line of sight along the road. A segmented guidance system is adopted: constant illumination at long distances provides stable guidance, flashing at medium distances enhances warnings, and constant illumination at close distances reduces visual fatigue. This effectively solves the problem of unstable visibility and warning effects of existing devices in the nose area at night and in low-visibility environments, and ensures guidance effectiveness under adverse conditions through a combination of active and passive illumination.

Description

Technical Field

[0001] This utility model belongs to the field of highway traffic safety technology, specifically relating to a highway nose-end nighttime driving safety enhancement device. Background Technology

[0002] With the continuous improvement of my country's expressway network and the rapid growth of motor vehicle ownership, the traffic flow on expressways is increasing day by day, and ensuring their safe operation has become a core issue in the transportation sector. Research data shows that the merging and diverging areas of expressways, as the intersection points of the main line and ramps, have become high-incidence areas for traffic accidents due to the characteristics of intersecting vehicle trajectories and significant speed differences. Especially at night, in low visibility conditions such as rain and fog, the accident rate in these areas is higher than that on ordinary road sections, mainly manifested as rear-end collisions, side collisions, and vehicles deviating from their lanes.

[0003] Currently, for safety protection in the merging and diverging areas (nose areas) of highways, existing technologies still mainly rely on passive facilities: on the one hand, reflective markings are used to define lane boundaries and nose positions, but the visibility of these markings is highly dependent on vehicle headlights, and the retroreflective effect is significantly reduced at night or in inclement weather. Furthermore, long-term wear and tear from vehicle traffic and rain erosion easily leads to fading and a continuous decline in their guidance function. On the other hand, while reflective warning signs installed on some sections provide textual warning information, they also rely on external light sources for reflection, making them difficult for drivers to recognize in time in low-light conditions, resulting in a significant delay in warning response. In addition, the application of existing active lighting devices is mostly limited to a single guidance function and lacks a systematic deployment plan; for example, scattered guide lights do not form a continuous visual guidance strip.

[0004] In summary, the visibility and warning effect of existing warning devices in the nose area are inconsistent at night and in low visibility environments. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a highway nose-end night driving safety enhancement device that addresses the shortcomings of the prior art. The device has a novel and reasonable design, simple structure, strong practicality, and is easy to promote and use.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A highway nose-end night driving safety enhancement device includes a night vision guidance component, a luminous warning component, a reflective guide component, and a power supply system, wherein the night vision guidance component, the luminous warning component, and the power supply system are electrically connected; The night vision guidance components are installed on the guardrails on both sides of the main line and the guardrails on both sides of the ramp in the designated area; the designated area is 1000m before and after the small nose points of the merging and diverging zones; the luminous warning components are installed behind the small nose points of the merging and diverging zones; the reflective guide components are installed in front of the small nose points of the merging and diverging zones. The night vision guidance component includes guidance lights; the guidance lights are continuously deployed within a set area; the guidance lights located on the left side of the driving direction are warm yellow guidance lights, and the guidance lights located on the right side of the driving direction are pure white guidance lights; the color temperature of the warm yellow guidance lights is 2500-3000K, and the color temperature of the pure white guidance lights is 5500-6000K. The night vision guidance component has two working modes: flashing and constant light. Within the set area, the guidance lights located 800-1000m in front of and 200-1000m behind the small nose points of the merging and diverging zones use constant light mode, the guidance lights located 200-800m in front of the small nose points of the merging and diverging zones use flashing mode, and the guidance lights located 200m before and after the small nose points of the merging and diverging zones use constant light mode.

[0007] Furthermore, the spacing between the LED beads in the induction lamp is 2–10 cm, and the brightness of a single LED bead is greater than 600 lx.

[0008] Furthermore, the guardrails include double-wave corrugated beam guardrails, triple-wave corrugated beam guardrails, and concrete guardrails; The guide lights are installed on the straight sections between the crests and the lower crests of the double-wave and triple-wave beam guardrails, and on the flat surfaces of the concrete guardrails.

[0009] Furthermore, the guide light is 60–120 cm above the ground.

[0010] Furthermore, the flashing frequency of the flashing mode is 40 to 60 times per minute.

[0011] Furthermore, the luminous warning component includes a warning sign body, on which luminous markings with text are provided, and the warning sign body is mounted on a bracket.

[0012] Furthermore, the reflective guide component employs a combination of white and yellow glass microsphere reflective materials, with the white glass microsphere reflective material having a retroreflection brightness coefficient ≥150. The retroreflective brightness coefficient of the yellow glass microsphere reflective material is ≥100. .

[0013] Furthermore, the power supply system is installed on the bracket and includes a solar power supply system, a mains power supply system, and a power control box that is connected to the solar power supply system and the mains power supply system.

[0014] This utility model has the following advantages compared with the prior art: This invention utilizes nighttime vision guidance components deployed in designated areas to clearly mark key areas of merging and diverging traffic, providing drivers with continuous visual guidance to help them prepare in advance and avoid traffic accidents caused by sudden changes in merging and diverging traffic. These components are deployed on both sides of the main road guardrails and on both sides of the ramps, ensuring effective guidance for vehicles traveling on both the main road and ramps. Simultaneously, luminous warning components are placed behind the small noses of the merging and diverging traffic areas to alert drivers that they have entered a critical area, prompting them to slow down and pay attention to their driving direction to reduce the risk of accidents. Reflective guide components are placed in front of the small noses to guide the driver's line of sight, allowing them to anticipate the road's direction. Through the active luminous nighttime vision guidance components and the passive luminous reflective guide components, effective guidance and warnings are provided to drivers even in adverse conditions, ensuring driving safety.

[0015] By using warm yellow and pure white guide lights on the left and right sides of the driving direction respectively, drivers can easily judge the left and right boundaries of the road at night. The continuous guide lights, like tracks, keep the driver's line of sight along the road, reducing safety hazards caused by deviated vision.

[0016] By employing segmented guidance to adapt to varying distance requirements, a constant-brightness mode is used in long-distance areas, providing stable visual guidance for the driver. A flashing mode is used in medium-distance areas, subconsciously alerting the driver and prompting them to prepare for slowing down or changing lanes in advance. A constant-brightness mode is used in close-range areas, providing stable visual guidance, reducing driver fatigue, and ensuring safe driving in critical areas.

[0017] This solves the problem of unstable visibility and warning effect of existing warning devices in the nose area at night and in low visibility environments.

[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0020] Example of a highway nose-end nighttime driving safety enhancement device: like Figures 1-7 As shown, the highway nose-end nighttime driving safety enhancement device includes a nighttime vision guidance component, a luminous warning component 2, a reflective guide component 3, and a power supply system. The nighttime vision guidance component and the luminous warning component 2 are electrically connected to the power supply system. The stability of nighttime vision guidance is ensured by the actively luminous nighttime vision guidance component and the passively luminous reflective guide component 3; that is, when the passive luminous component's effectiveness decreases due to dense fog or poor weather conditions, the active luminous component can still be relied upon; when the power supply is unstable and the active luminous component fails, the passive luminous component can still be relied upon; thus ensuring that the warning device can reliably warn the driver.

[0021] The aforementioned nighttime visibility guidance components are installed on the guardrails 9 on both sides of the main line and the guardrails 10 on both sides of the ramps within the designated area; the designated area is 1000m before and after the small nose points 7 of the merging and diverging zones; the aforementioned luminous warning components 2 are installed behind the small nose points 7 of the merging and diverging zones; the aforementioned reflective guide components 3 are installed in front of the small nose points 7 of the merging and diverging zones. By installing nighttime visibility guidance components on the guardrails 9 on both sides of the main line within the designated area, the continuously deployed guidance lights 1 provide long-distance active luminous guidance to drivers, and the luminous warning components 2 remind drivers from close range that appropriate actions can be taken; thus completing the visibility guidance for merging and diverging.

[0022] The night vision guidance component includes guidance lights 1; these guidance lights 1 are continuously deployed within a designated area; the guidance lights 1 located on the left side of the driving direction use warm yellow guidance lights, and the guidance lights 1 located on the right side of the driving direction use cool white guidance lights; the color temperature of the warm yellow guidance lights is 2500–3000K, and the color temperature of the cool white guidance lights is 5500–6000K. By placing warm yellow guidance lights on the left and cool white guidance lights on the right, the driver can intuitively distinguish the left and right boundaries of the lane. At highway ramp entrances, the warm yellow guidance lights on the left and the cool white guidance lights on the right can guide vehicles smoothly from the main road into the ramp or from the ramp into the main road. The guidance lights 1 are 60–120 cm above the ground.

[0023] The night vision guidance component has two operating modes: flashing and constant illumination. Within the designated area, the guide lights 1 located 800-1000m before and 200-1000m after the merging / diversion point 7 operate in constant illumination mode; the guide lights 1 located 200-800m before the merging / diversion point 7 operate in flashing mode; and the guide lights 1 located 200m before and after the merging / diversion point 7 operate in constant illumination mode. The flashing frequency is 40-60 times per minute. It should be noted that the 800-1000m and 200-800m areas before and after the merging / diversion point 7 refer to the distance extending along the main line in the direction of oncoming traffic, starting from the merging / diversion point 7. By using constant light to outline the road at long distances, flashing light to enhance the warning signal at medium distances, and switching back to constant light at close distances, the guide lights precisely define the lanes to facilitate driver operation. This progressive coordination provides drivers with a continuous and well-defined visual cue at night.

[0024] To avoid glare and visual fatigue, the spacing between the LED beads in the guide light 1 is 2–10 cm, and the brightness of each individual LED bead is greater than 600 lx. This appropriate spacing ensures the driver's visual comfort.

[0025] To extend the service life of the guide light 1, the guardrail includes a double-wave corrugated beam guardrail 4, a triple-wave corrugated beam guardrail 5, and a concrete guardrail 6. The guide light 1 is installed on the straight section between the crests of the waves on the guardrail panels of the double-wave corrugated beam guardrail 4 and the triple-wave corrugated beam guardrail 5, while the guide light 1 is installed on the flat surface of the concrete guardrail 6. This ensures that the performance of the guide light 1 is not affected as much as possible when the guardrail is impacted, and also facilitates the stable installation of the guide light 1.

[0026] The luminous warning component 2 includes a warning sign body 11, on which a luminous label with text is provided. The luminous label with text is positioned as "Merging area ahead, please slow down" or "Diverging area ahead, please slow down". The warning sign body is mounted on a bracket 8. The reflective warning and power supply system share a bracket 8.

[0027] To ensure reflectivity, the reflective guide component 3 uses a combination of white and yellow glass microsphere reflective materials. The retroreflective brightness coefficient of the white glass microsphere reflective material is ≥150. The retroreflective brightness coefficient of the yellow glass microsphere reflective material is ≥100. .

[0028] The power supply system is installed on the bracket 8. The power supply system includes a solar power supply system 13, a mains power supply system, and a power control box 12 that is connected to the solar power supply system 13 and the mains power supply system for easy switching of the power supply system according to actual needs.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
