Description

Technical Field

[0001] This invention relates to the field of traffic diversion equipment technology, and more specifically, to a smart traffic diversion device and method. Background Technology

[0002] Smooth traffic flow is a core cornerstone for efficient urban operation, unleashing economic vitality, and improving people's well-being. Its importance is reflected in multiple dimensions, including economic, environmental, social, and safety aspects. With the rapid development of urban economies, the number of motor vehicles on the road is increasing daily, making traffic management increasingly important. Traffic guidance equipment, by endowing the traffic system with the capabilities of perception, interconnection, analysis, prediction, and control, fully ensures traffic safety, maximizes the effectiveness of traffic infrastructure, and improves the operational efficiency and management level of the traffic system, thus providing support for smooth travel.

[0003] In practical use, traffic lights may malfunction due to power outages, damage, repairs, or replacement needs. In such cases, temporary emergency traffic signal equipment is required for traffic guidance. However, existing emergency traffic signal equipment is mostly designed for common intersections or T-junctions, with indicator lights only installed in fixed directions. When facing irregular or asymmetrical intersections, the indicator lights cannot align with the roads to be directed, making it difficult to meet the needs of lane signal indication and traffic guidance at intersections.

[0004] Meanwhile, irregular intersections often have complex road layouts and adjacent roads are too close together. This makes the traffic lights on adjacent roads highly similar in direction, which can easily cause confusion and misjudgment for drivers when making quick judgments. Existing emergency traffic signal equipment is difficult to effectively avoid this inherent defect in its design. If each irregular intersection is equipped with a dedicated emergency traffic signal device that is perfectly matched to it, the deployment process will not only be time-consuming and labor-intensive, but will also seriously delay the critical timeliness of traffic management. Furthermore, the large variety of equipment and the complexity of transportation and scheduling will significantly increase the overall operating and logistics costs.

[0005] Therefore, there is an urgent need for a smart traffic diversion device and method to solve the aforementioned problem of how to deal with irregular and asymmetrical intersections in emergency traffic diversion. Summary of the Invention

[0006] The purpose of this invention is to provide a smart traffic guidance device and method, which can adjust the device settings according to road information and control the working status of indicator lights, warning lights and arc-shaped light shields according to traffic status information, so as to avoid misleading vehicle drivers by similar intersection indicator lights.

[0007] The embodiments of the present invention are implemented as follows: This invention provides an intelligent traffic guidance device, comprising a main support rod and a control assembly. The main support rod is equipped with multiple indicator components, each including a fixed ring disk with a rotating ring disk rotatably connected to it. The rotating ring disk is equipped with a first driving mechanism for rotating the rotating ring disk around the main support rod. An indicator light and a camera are located on the outer side of the rotating ring disk; the camera collects traffic information at the intersection. Arc-shaped light-shielding plates are hinged to both sides of the indicator light, extending in an arc along the circumference of the rotating ring disk, with their rotation axis parallel to the axis of the rotating ring disk. A second driving mechanism is located on the rotating ring disk for driving the arc-shaped light-shielding plates to rotate. A warning light is located on the side of the arc-shaped light-shielding plate closest to the indicator light; when the arc-shaped light-shielding plate rotates to be perpendicular to the indicator light, the light emission direction of the warning light is consistent with that of the indicator light. The control assembly includes a communication unit for receiving traffic flow information from nearby roads. The control assembly controls the indicator light, warning light, first driving mechanism, and second driving mechanism to operate based on the traffic information and traffic flow information.

[0008] In some embodiments of the present invention, the arc-shaped light-shielding plate has a plurality of vertically spaced light-transmitting gaps; when the arc-shaped light-shielding plate is rotated to be perpendicular to the indicator light, the extending direction of the vertically spaced light-transmitting gaps points towards the indicator light.

[0009] In some embodiments of the present invention, the above-mentioned arc-shaped light-shielding plate is a louver structure, the louver structure includes blades, the vertical light-transmitting gap is composed of two blades, and the tilt angle of the blades can be adjusted.

[0010] In some embodiments of the present invention, a telescopic connecting rod is provided on the rotating ring disk, and the back of the indicator light is hinged to the telescopic connecting rod; the telescopic connecting rod adjusts the distance between the indicator light and the fixed ring disk by telescopic adjustment.

[0011] In some embodiments of the present invention, the main support rod is provided with a first vertical slide groove, the fixed ring disk is slidably connected to the first vertical slide groove and is provided with a third driving mechanism, the third driving mechanism being used to drive the fixed ring disk to move on the first vertical slide groove.

[0013] In some embodiments of the present invention, an outer cylinder is further included, a middle cylinder is slidably sleeved on the inner side of the outer cylinder, and an inner cylinder is slidably sleeved on the inner side of the middle cylinder; a fixing post is disposed on the inner side of the outer cylinder, and the top of the second sliding post is connected to the inner cylinder; an indicator component is detachably connected to the top of the inner cylinder; and a first vertical groove is disposed on the outer side of the inner cylinder.

[0014] This invention provides a smart traffic guidance device and method, specifically including the following steps: The camera collects traffic information at the intersection, and the first drive mechanism drives the rotating disc to rotate and adjust the direction of the indicator lights according to the traffic information; wherein, the traffic information includes the intersection geometry, traffic signs and markings, lane occupancy rate and vehicle queue length. If the angle between the light-emitting directions of the two indicator lights is less than 60°, the indicator light of the relevant indicator light will work and the second drive mechanism will rotate the arc-shaped light shield to be perpendicular to the indicator light so that vehicles at adjacent intersections cannot see the indicator light. The system receives traffic flow information from nearby roads via a communication unit. This traffic flow information includes lane occupancy and vehicle queue length at nearby intersections. The control component controls the indicator lights to guide traffic based on road condition and traffic flow information.

[0015] In some embodiments of the present invention, when the indicator light is in operation, the blade angle of the arc-shaped light shield is rotated and adjusted so that the vertical light-transmitting gap faces the vehicles at the intersection on the adjacent side.

[0016] In some embodiments of the present invention, the height spacing between the two indicator components is adjusted according to the angle between the light emission directions of their indicator lights; the smaller the angle, the greater the height spacing between the two indicator components.

[0017] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: Existing emergency traffic signal equipment cannot provide targeted pedestrian and vehicle guidance based on intersections and nearby road conditions, cannot adjust traffic lights to suit different road conditions, and has poor signal indication; moreover, it cannot avoid misleading situations caused by traffic lights at similar intersections. This invention provides a smart traffic guidance device and method, including a main support rod and a control assembly. The main support rod is equipped with multiple indicator components, each including a fixed ring disk with a rotating ring disk rotatably connected to it. The rotating ring disk is equipped with a first driving mechanism for rotating the rotating ring disk around the main support rod. An indicator light and a camera are located on the outer side of the rotating ring disk; the camera collects traffic information at the intersection. Arc-shaped light-shielding plates are hinged to both sides of the indicator light, extending in an arc along the circumference of the rotating ring disk, with their rotation axis parallel to the axis of the rotating ring disk. A second driving mechanism is located on the rotating ring disk for driving the arc-shaped light-shielding plates to rotate. A warning light is located on the side of the arc-shaped light-shielding plate closest to the indicator light; when the arc-shaped light-shielding plate rotates to be perpendicular to the indicator light, the light emission direction of the warning light is consistent with that of the indicator light. The control assembly includes a communication unit for receiving traffic flow information from nearby roads. The control assembly controls the indicator light, warning light, first driving mechanism, and second driving mechanism to operate based on the traffic information and traffic flow information.

[0018] This invention utilizes a rotating ring disk rotatably connected to a fixed ring disk of the indicator component, allowing the rotating ring disk to rotate around a main support rod under the action of a first driving mechanism. Multiple cameras corresponding to indicator lights on the indicator components can accurately collect road and traffic status information. The indicator lights can adjust their orientation according to the specific conditions of the intersection, enabling this invention to adapt to irregular and asymmetrical intersections. Simultaneously, this invention features curved light shields hinged to both sides of the indicator lights. When the angle between two adjacent roads and the intelligent traffic guidance device is small, the curved light shields rotate to be perpendicular to the indicator lights, and the indicator lights on the curved light shields activate and are positioned on either side of the indicator lights. This allows them to alert vehicles in the corresponding lanes of the indicator lights and effectively focus their attention through flashing. Through spatial positioning and temporal synchronization, this helps drivers distinguish the corresponding indicator lights, effectively reducing the misjudgment rate at intersections. Furthermore, the curved light shields effectively prevent vehicles in adjacent roads from observing the indicator lights and warning lights, further avoiding misjudgments. In addition, the indicator lights installed on the curved sunshade are not only positioned on both sides of the indicator lights when in operation, but also maintain a certain distance from the indicator lights. This allows the driver's attention to naturally shift from the indicator lights to the indicator lights, reducing cognitive load, while also preventing the indicator lights from affecting the indicator light source and causing observation obstacles.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] Example: Please refer to Figure 1-8 This embodiment provides a smart traffic guidance device, which includes a main support rod 2 and a control assembly. Multiple indicator components 1 are mounted on the main support rod 2. Each indicator component 1 includes a fixed ring disc 6, on which a rotating ring disc 7 is rotatably connected. The rotating ring disc 7 is equipped with a first driving mechanism for rotating the rotating ring disc 7 around the main support rod 2. An indicator light 12 and a camera 13 are mounted on the outer side of the rotating ring disc 7. The camera 13 is used to collect traffic information at the intersection. Arc-shaped light-shielding plates 42 are hinged to both sides of the indicator light 12, and the arc-shaped light-shielding plates 42 are arranged along the circumferential arc of the rotating ring disc 7. The arc-shaped light shield 42 extends in shape, with its rotation axis parallel to the axis of the rotating ring disk 7. A second drive mechanism is provided on the rotating ring disk 7 to drive the arc-shaped light shield 42 to rotate. An indicator light 41 is provided on the side of the arc-shaped light shield 42 near the indicator light 12. When the arc-shaped light shield 42 rotates to be perpendicular to the indicator light 12, the light emission direction of the indicator light 41 is consistent with that of the indicator light 12. The control component includes a communication unit, which is used to receive road condition information of nearby roads. The control component controls the operation of the indicator light 12, the indicator light 41, the first drive mechanism, and the second drive mechanism according to the road condition information and traffic flow information.

[0025] Existing emergency traffic signal equipment cannot provide targeted pedestrian and vehicle guidance based on intersections and adjacent road conditions, nor can it adapt the indicator lights 12 to different road conditions, resulting in poor signal indication. Furthermore, it cannot prevent misleading situations caused by indicator lights 12 at similar intersections. This invention addresses this by rotatably connecting a rotating ring 7 to the fixed ring 6 of the indicator component 1. This rotating ring 7 can rotate around the main support rod 2 under the action of a first driving mechanism. Multiple cameras 13 corresponding to the indicator lights 12 on the indicator components 1 can accurately collect road and traffic information. The indicator lights 12 can adjust their orientation according to the specific conditions of the intersection, allowing this invention to adapt to irregular and asymmetrical intersections.

[0026] Meanwhile, the present invention features curved light shields 42 hinged to both sides of the indicator light 12. When the angle between two adjacent roads and the intelligent traffic guidance device is small, the curved light shields 42 rotate to be perpendicular to the indicator light 12. The indicator lights 41 on the curved light shields 42 then operate and are positioned on both sides of the indicator light 12, allowing them to alert vehicles in the corresponding lanes of the indicator light 12 and effectively focus their attention through flashing. Through spatial positioning and temporal synchronization, this helps drivers distinguish the corresponding indicator light 12, effectively reducing the misjudgment rate at intersections. Furthermore, the curved light shields 42 effectively prevent vehicles in adjacent roads from observing both the indicator lights 41 and the indicator light 12, further preventing misjudgment. In addition, the indicator lights 41 on the curved light shields 42 are not only positioned on both sides of the indicator light 12 during operation but also maintain a certain distance from it. This allows the driver's attention to naturally shift from the indicator lights 41 to the indicator light 12, reducing cognitive load while preventing the indicator lights 41 from affecting the light source of the indicator light 12 and causing observation obstacles. Understandably, the second drive mechanism can be selected from common structural configurations available on the market, such as using a drive motor to rotate the arc-shaped light shield 42 via gear transmission.

[0027] In some embodiments of the present invention, the arc-shaped light shield 42 has multiple vertically spaced light-transmitting gaps 14; when the arc-shaped light shield 42 is rotated to be perpendicular to the indicator light 12, the extending direction of the vertically spaced light-transmitting gaps 14 points towards the indicator light 12. The arc-shaped light shield 42 can block the indicator light 12 and the warning light 41, avoiding misjudgment caused by observation from adjacent roads. However, complete blocking may prevent drivers on the side from accurately judging the signal status. For example, if they can only observe the corresponding indicator light 12, they may hesitate or mistakenly enter the intersection when the yellow light is flashing, indicating a long-term flashing warning to slow down or when the traffic light is changing. By setting vertically spaced light-transmitting gaps 14 on the arc-shaped light shield 42, drivers on adjacent roads can observe part of the light source of the indicator light 12 through the vertically spaced light-transmitting gaps 14, thereby judging the traffic status of adjacent lanes and avoiding misjudgment. At the same time, the vertically spaced light-transmitting gaps 14 effectively cut off the light from the indicator light 12 of non-corresponding lanes, forming a clear distinction from the corresponding indicator light 12 except for the warning light 41, effectively achieving the distinction of the corresponding indicator light 12, and isolating the warning without blocking observation.

[0028] In some embodiments of the present invention, the arc-shaped light shield 42 is a louver structure, which includes blades. The vertical light-transmitting gap 14 is composed of two blades, and the tilt angle of the blades can be adjusted. The louver structure of the arc-shaped light shield 42 allows for adjustment of the light-transmitting width and direction of the vertical light-transmitting gap 14 relative to adjacent lanes by rotating the blades, enabling targeted adjustments to adapt to similar intersections. It is understood that the arc-shaped light shield 42 adopts a commonly available louver structure and is equipped with a drive structure to control the rotation of the blades.

[0029] In some embodiments of the present invention, a telescopic connecting rod 11 is provided on the rotating ring disk 7, and the back of the indicator light 12 is hinged to the telescopic connecting rod 11; the telescopic connecting rod 11 adjusts the distance between the indicator light 12 and the fixed ring disk 6 by telescoping. The telescopic connecting rod 11 is a telescopic structure, which can not only prevent the indicator lights 12 on different fixed ring disks 6 from affecting each other, but also allow the indicator lights 12 to extend outward, increasing the distance between two adjacent indicator lights 12, further preventing misjudgment by the driver. By adjusting the tilt angle of the indicator light 12 through the hinge structure, the indicator light 12 is positioned directly facing the vehicle on the sloping road surface, further improving visibility.

[0030] In some embodiments of the present invention, a first vertical slide groove 4 is provided on the main support rod 2, and a fixed ring plate 6 is slidably connected to the first vertical slide groove 4 and provided with a third driving mechanism. The third driving mechanism is used to drive the fixed ring plate 6 to move on the first vertical slide groove 4. By providing the first vertical slide groove 4, the present invention allows the fixed ring plate 6 to be height-adjusted under the action of the third driving mechanism. Different height settings can effectively prevent drivers from confusing the indicator lights 12 of similar roads. Furthermore, different intersections have different road directions, obstacle distributions, and road slopes. The present invention uses indicator lights 12 whose height and direction can be adjusted individually to flexibly adjust according to the actual conditions of the intersection. With the help of the camera 13 monitoring the real-time situation of the intersection, the height of the indicator lights 12 can be adjusted in a targeted manner to make them easier for distant vehicles to identify.

[0031] Existing emergency traffic signal equipment can only guide pedestrians and vehicles according to pre-set programs, and cannot effectively achieve traffic flow management. It cannot provide targeted guidance based on the intersection and adjacent road conditions, often resulting in a continuous influx of vehicles into already congested areas, further exacerbating the congestion. Even with emergency signal equipment, high-traffic intersections often require real-time police intervention, wasting manpower and resources. This invention addresses this by using a camera 13 to collect vehicle information at the intersection, and a control component to precisely adjust the indicator light 12 based on lane occupancy and queue length. The control component can also control the rotation of the rotating structure based on road information collected by the camera, thus guiding traffic flow through the indicator light 12. Furthermore, the camera can collect vehicle information at the intersection, and the control component can precisely adjust the indicator light 12 based on lane occupancy and queue length.

[0032] In some embodiments of the present invention, the first driving mechanism includes a first driving motor 10, which is mounted on a fixed ring disk 6. A rotating gear ring 8 is fixedly mounted on a rotating ring disk 7. The output shaft of the first driving motor 10 is provided with a first gear 9, which meshes with the rotating gear ring 8.

[0033] In some embodiments of the present invention, the third driving mechanism includes a second driving motor 39, which is mounted on the fixed ring disk 6. The output shaft of the second driving motor 39 is provided with a second gear 40, and the first vertical slide groove 4 is provided with a vertical rack 5. The second gear 40 meshes with the vertical rack 5. The second driving motor 39 drives the second gear 40 to rotate, thereby causing the fixed ring disk 6 to adjust its height on the main support rod 2.

[0034] The indicator component 1 is provided with at least 4 units. The provision of at least 4 indicator components is suitable for most road conditions. If a few multi-way intersections require the use of this device, the ease of installation and disassembly can be adjusted by adding indicator components 1 to improve its applicability.

[0035] In some embodiments of the present invention, the upper surface of the bottom component 3 is provided with a storage groove 15 for accommodating the indicator component 1 and the main support rod 2, and the main support rod 2 is hinged to the bottom component 3; an auxiliary rod 38 is hinged to the bottom component 3, and one end of the auxiliary rod 38 is detachably connected to the telescopic rod. Emergency traffic signal equipment often faces transportation issues. Currently existing emergency equipment has a fixed structure and occupies a large space during transportation, requiring specialized work vehicles for transportation. Deploying specialized work vehicles when a single intersection malfunctions wastes resources; while during large-scale power outages, the transportation capacity of a single vehicle is limited by the space occupied by the emergency equipment, making transportation and setup extremely inconvenient. The storage groove 15 on the upper surface of the bottom component 3 allows the indicator component 1 and the main support rod 2 to be stored in the storage groove 15 when the device is not in use, facilitating the transportation of the device. Furthermore, the top of the bottom component 3 is detachably equipped with a top cover 5 to protect the indicator light 12 below; the top cover 5 can be set as a photovoltaic panel and equipped with a matching circuit to supplement the energy supply structure.

[0036] Different intersection conditions require indicator lights 12 at different heights to avoid obstruction by trees or other obstacles. When the intersection is unobstructed, a higher indicator light 12 makes it easier for vehicles at a distance to see it in advance. The telescopic pole is hinged at both ends to the indicator component 1 and the bottom component 3, respectively. This allows the telescopic pole to retract and fold down when needed for transport or storage, reducing the overall thickness of the device for easier storage and placement on frequently used vehicles. The auxiliary rod 38 provides support for the telescopic pole when it is vertical, ensuring its stability. Understandably, the hinge structure can be a commonly available design, and the hinge structure includes a fixing device to secure it when rotation is not required, preventing unnecessary rotation.

[0037] In some embodiments of the present invention, the main support rod 2 includes a fixed column 16, a second vertical slide groove 19 is provided on the fixed column 16, a first sliding column 17 is slidably connected to the second vertical slide groove 19, a third vertical slide groove 20 is provided on the first sliding column 17, and a second sliding column 18 is slidably connected to the third vertical slide groove 20; a drive shaft 21 and a transmission shaft 25 are provided on the first sliding column 17, a transmission belt 22 is provided on the drive shaft 21 and the transmission shaft 25, and a third drive motor 26 is provided on the drive shaft 21; a first connecting block 23 is provided at the top of the fixed column 16 and is fixedly connected to the transmission belt 22, and a second connecting block 24 is provided at the bottom of the second sliding column 18 and is fixedly connected to the transmission belt 22. The third drive motor 26 drives the drive shaft 21 to rotate, which can drive the transmission belt 22 to move, thereby causing the first sliding column 17 and the second sliding column 18 to move up or down, so that the indicator component 1 on the main support rod 2 can be adjusted in height; and the main support rod 2 has a simple structure and is easy to inspect, repair and replace.

[0038] In some embodiments of the present invention, an outer cylinder 27 is further included, with a middle cylinder 28 slidably sleeved on the inner side of the outer cylinder 27, and an inner cylinder 29 slidably sleeved on the inner side of the middle cylinder 28; a fixing post 16 is disposed on the inner side of the outer cylinder 27, and the top of the second sliding post 18 is connected to the inner cylinder 29; an indicator component 1 is detachably connected to the top of the inner cylinder 29; and a first vertical sliding groove 4 is disposed on the outer side of the inner cylinder 29. The outer cylinder 27, middle cylinder 28, and inner cylinder 29, which are sleeved together, can effectively protect the main support rod 2 inside.

[0039] In some embodiments of the present invention, the bottom component 3 includes a base 36, and a friction base 35 is provided on the lower end surface of the base 36; a movable structure 37 is provided on the bottom of the base 36, and the friction base 35 and the movable structure 37 are connected by a telescopic column; the telescopic column includes an outer column 30, an inner column 31 is slidably sleeved on the outer column 30, a fourth drive motor 32 is provided on the outer column 30, a threaded rod 33 is provided on the output shaft of the fourth drive motor 32, and a threaded hole 34 is provided on the inner column 31 and threadedly connected to the threaded rod 33. The friction base 35 provided on the lower end surface of the base 36 can prevent unnecessary movement of the device; the provision of the telescopic column allows the telescopic column to extend when the device needs to be fixed, and the friction base 35 to support the device and prevent movement; when the device needs to be moved, the telescopic column retracts, the friction base 35 retracts, and the movable structure 37 contacts the ground to move the device. The fourth drive motor 32 controls the rotation of the threaded rod 33, causing the inner column 31 to extend and retract relative to the outer column 30. This not only enables extension and retraction but also prevents the telescopic column from shrinking due to the weight of the device, thus ensuring structural stability.

[0040] In some embodiments of the present invention, a remote controller is also included. The remote controller is communicatively connected to the control component for controlling the indicator light 12 and the moving structure 37. The remote controller allows traffic controllers to directly control the movement of the device and the changing of the indicator light 12, thus preventing personnel from being placed in dangerous areas at intersections.

[0041] This invention provides a smart traffic diversion method, which specifically includes the following steps: The camera collects traffic information at the intersection, and the first drive mechanism drives the rotating disc to rotate and adjust the direction of the indicator lights according to the traffic information; wherein, the traffic information includes the intersection geometry, traffic signs and markings, lane occupancy rate and vehicle queue length. If the angle between the light-emitting directions of the two indicator lights is less than 60°, the indicator light of the relevant indicator light will work and the second drive mechanism will rotate the arc-shaped light shield to be perpendicular to the indicator light so that vehicles at adjacent intersections cannot see the indicator light. The system receives traffic flow information from nearby roads via a communication unit. This traffic flow information includes lane occupancy and vehicle queue length at nearby intersections. The control component controls the indicator lights to guide traffic based on road condition and traffic flow information.

[0042] In some embodiments of the present invention, when the indicator light is in operation, the blade angle of the arc-shaped light shield is rotated and adjusted so that the vertical light-transmitting gap faces the vehicles at the intersection on the adjacent side.

[0043] Specifically, after the intelligent traffic guidance device reaches the corresponding intersection, it collects road information through camera 13, and the connecting rod 11 in the indicator component 1 adjusts its direction according to the intersection geometry. Camera 13 collects intersection information such as traffic flow, vehicle speed, lane occupancy, and vehicle queue length. The control component controls the indicator lights to guide traffic flow and prevent congestion at intersections caused by vehicle stagnation based on road and traffic information. After observing through the camera, the angle between the adjacent road and the intelligent traffic guidance device is used to determine whether there is a possibility of misjudgment by the adjacent indicator light 12. If the angle is less than 60°, the indicator light 41 is activated and the arc-shaped light shield 42 is rotated to be perpendicular to the indicator light 12 to prevent adjacent lanes from seeing the indicator light 41. At the same time, the blades on the arc-shaped light shield 42 rotate, allowing drivers of vehicles on adjacent roads to observe the indicator light 12 through the vertical light transmission gap 14.

[0044] In some embodiments of the present invention, the height spacing between the two indicator components is adjusted according to the angle between the light emission directions of their indicator lights; the smaller the angle, the greater the height spacing between the two indicator components. The height spacing between the two indicator components is inversely proportional to the angle, further preventing driver misjudgment.

[0045] In some embodiments of the present invention, when the queue length of vehicles at an adjacent intersection exceeds the average queue length of vehicles on the road corresponding to that intersection, the passage time of the traffic guidance indicator light at the adjacent intersection is shortened, so that the traffic guidance at the intersection can be coordinated with the road conditions of the adjacent road, and avoid the situation where the traffic guidance at the intersection exceeds the capacity limit of the adjacent road, causing congestion.

[0046] In summary, the embodiments of the present invention provide a smart traffic guidance device and method. The present invention rotatably connects a rotating ring disk 7 to the fixed ring disk 6 of the indicator component 1, so that the rotating ring disk 7 can rotate around the main support rod 2 under the action of the first driving mechanism; the cameras 13 corresponding to the indicator lights 12 on the multiple indicator components 1 can accurately collect road information and traffic status information, and the indicator lights 12 can adjust their orientation according to the specific conditions of the intersection, so that the present invention can adapt to irregular and asymmetrical intersections. Meanwhile, the present invention features curved light shields 42 hinged to both sides of the indicator light 12. When the angle between two adjacent roads and the intelligent traffic guidance device is small, the curved light shields 42 rotate to be perpendicular to the indicator light 12. The indicator lights 41 on the curved light shields 42 then operate and are positioned on both sides of the indicator light 12, allowing them to alert vehicles in the corresponding lanes of the indicator light 12 and effectively focus their attention through flashing. Through spatial positioning and temporal synchronization, this helps drivers distinguish the corresponding indicator light 12, effectively reducing the misjudgment rate at intersections. Furthermore, the curved light shields 42 effectively prevent vehicles in adjacent roads from observing both the indicator lights 41 and the indicator light 12, further preventing misjudgment. In addition, the indicator lights 41 on the curved light shields 42 are not only positioned on both sides of the indicator light 12 during operation but also maintain a certain distance from it. This allows the driver's attention to naturally shift from the indicator lights 41 to the indicator light 12, reducing cognitive load while preventing the indicator lights 41 from affecting the light source of the indicator light 12 and causing observation obstacles.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
