Description

Technical Field

[0001] This invention relates to the field of traffic control technology, specifically to a traffic flow diversion control system and guidance method for urban traffic intersections. Background Technology

[0002] In modern intelligent transportation environments, transportation systems need to be able to rationally allocate traffic flow to reduce road congestion, reduce time costs for road users, and reduce traffic accidents. Quickly alleviating or resolving existing traffic congestion is a crucial component of intelligent transportation. Current methods for resolving traffic congestion primarily focus on prevention, using road condition monitoring to predict congestion in advance and then using intelligent navigation and route planning to inform drivers of road conditions in advance so they can avoid congested areas. However, these methods have drawbacks: they are insufficient for resolving existing congestion and cannot address queuing congestion at diversion points; furthermore, road condition alerts are delayed, meaning vehicles may have already entered congested areas after receiving congestion warnings and cannot change routes. Even if the monitoring system promptly warns of traffic congestion, vehicles at diversion points often have no way to avoid it due to the need to change lanes, inevitably leading to congestion. The current solution to existing traffic congestion mainly involves quickly dispatching traffic police to the congestion points to direct and disperse the congested vehicles. However, this method wastes police resources, is slow, and can lead to insufficient police force during peak hours and weekends when urban traffic is congested. In addition, existing urban traffic diversion methods are difficult to effectively divert traffic by combining real-time traffic flow with traffic lights and lane guidance, and their effectiveness is generally limited.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a textile dye mixing device [CN202110319299.7], which includes a monitoring unit, a computing unit, a communication unit, and a road guidance light device. The control method includes: the monitoring unit collects vehicle information in the monitoring area and transmits it to the computing unit; the computing unit runs a congestion judgment algorithm to analyze the road congestion situation in a timely manner and reports the road conditions to the traffic management platform; the computing unit starts a vehicle turning recognition algorithm; outputs individual turning intention data for each vehicle; the server runs an intelligent path planning algorithm: generates a turning guidance light control strategy within the monitoring area based on the vehicle turning intention data; and converts all path plans into control information for the road guidance light device.

[0004] The above solution addresses to some extent the problems of delayed traffic diversion and waste of resources caused by manual traffic control in existing technologies. However, the solution still has many shortcomings. For example, existing urban traffic congestion diversion methods are difficult to effectively divert traffic by combining real-time traffic flow with traffic lights and lane guidance, and their effectiveness is generally limited. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a traffic flow diversion control system for urban traffic intersections.

[0006] The purpose of this invention is to address the above-mentioned problems by providing a method for traffic flow diversion and guidance at urban traffic intersections.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a traffic flow diversion control system for urban traffic intersections, including a traffic flow monitoring mechanism connected to a traffic light control platform.

A sliding solar panel that can be linked with the sliding protective structure is provided on one side of the indicator column. Multi-way lane guide lines corresponding to each lane are provided at the intersection.

[0008] This application achieves the goal of resolving congestion in advance by using a traffic flow monitoring agency to monitor road sections that are about to become congested in real time, and by controlling and adjusting the four-way traffic signal lights at the previous intersection through a traffic light control platform, and by coordinating with multi-way lane guide lines to divert vehicles from the previous road section, thus preventing too many vehicles from entering the next congested road section. The application is effective.

[0009] In the aforementioned traffic flow diversion control system for urban traffic intersections, the traffic flow monitoring mechanism includes an infrared remote sensing camera for monitoring the length of traffic flow within the lanes, and a traffic flow speed sensor is installed at the intersection.

The automatic diversion control mode adjusts the four-way traffic signal indicator lights at the previous intersection based on the real-time traffic flow information of the traffic flow database of the next road segment obtained by the traffic flow monitoring agency. The manual diversion control mode actively adjusts the traffic signal indicator lights using the operating platform and mobile terminal. The four-way traffic signal indicator lights are equipped with a signal receiving module for receiving control signals, a positioning module, and a fault detection module.

The traffic signal display screens are divided into daily guidance mode and diversion guidance mode, and the traffic diversion switch screens are used to display the activation status of the daily guidance mode and the diversion guidance mode, wherein:

[0012] ① If a red light is displayed on the traffic diversion switch screen, it means that the diversion guidance state of the traffic signal indicator screen is not enabled. Use the normal guidance state and disable the diversion guidance state.

[0013] ② If a green light is displayed on the traffic diversion switch screen, it means that the diversion guidance mode of the traffic signal indicator screen is in use and the daily guidance mode is disabled.

[0014] The traffic diversion switch screen has a status switching countdown module.

[0015] In the above-mentioned traffic flow diversion control system for urban traffic intersections, the indicator light column is provided with several annular mounting slots, and the four-way traffic signal indicator lights are fixed in the annular mounting slots through the mounting connection part.

[0018] In the aforementioned traffic flow diversion control system for urban traffic intersections, the sliding solar panel includes a solar panel with an indicator light column facing south. The lower back of the solar panel is provided with an automatic retraction rod and the upper back is provided with an elastic connector.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1-10As shown, a traffic flow diversion control system for an urban traffic intersection includes a traffic flow monitoring mechanism 1, which is connected to a traffic light control platform 2. The traffic light control platform 2 is connected to a four-way traffic signal indicator 3 located at the intersection. The four-way traffic signal indicator 3 is installed on an indicator pillar 4, and the indicator pillar 4 has a built-in sliding protective structure 5. A sliding solar panel 6 that can be linked with the sliding protective structure 5 is provided on one side of the indicator pillar 4. A multi-way lane guide line 8 is provided at the intersection and is connected to each lane 7.

[0038] Traffic flow monitoring agency 1 monitors the traffic flow of the next road segment in real time. When congestion occurs, traffic light control platform 2 adjusts the four-way traffic signal indicator 3 at the intersection of the previous road segment to prevent the traffic flow of the previous road segment from continuing to merge. At the same time, it adjusts the four-way traffic signal indicator 3 at the intersection of the congested road segment so that the congested lane can quickly divert traffic according to the direction of the four-way traffic signal indicator 3 and the multi-way lane guide line 8, thereby achieving the purpose of alleviating congestion.

[0039] The traffic flow monitoring mechanism 1 includes an infrared remote sensing camera 11 for monitoring the length of traffic flow in lane 7, and a traffic flow speed sensor 12 is installed at the intersection. The traffic flow speed sensor 12, the infrared remote sensing camera and the traffic flow database 13 of the traffic flow monitoring mechanism 1 are connected, and the traffic flow database 13 transmits data to the traffic light control platform 2 through a wireless module.

[0040] The traffic flow speed sensor 12 is used to determine the speed of the traffic flow, the infrared remote sensing camera detects the length of the traffic flow, and the traffic light control platform 2 determines in advance whether congestion will occur based on the length of the traffic flow and the speed of the traffic flow.

[0041] Obviously, the traffic light control platform 2 has an automatic diversion control mode and a manual diversion control mode. The automatic diversion control mode adjusts the four-way traffic signal indicator 3 at the previous intersection based on the real-time traffic flow information of the traffic flow database 13 of the next road segment by the traffic flow monitoring agency 1. The manual diversion control mode actively adjusts the traffic signal indicator 3 using the operation platform 21 and the mobile terminal 22. The four-way traffic signal indicator 3 is equipped with a signal receiving module 31 for receiving control signals, a positioning module 32 and a fault detection module 33. The positioning module 32 and the fault detection module 33 are connected to the traffic light control platform 2 through the signal sending module 34.

[0042] The positioning module 32 is used to locate the four-way traffic signal indicator 3, which facilitates timely location in case of malfunction. The manual diversion control mode is used for traffic flow guidance and diversion in special situations, such as traffic accidents or special vehicles passing by. It adjusts the four-way traffic signal indicator 3 at the previous intersection to prevent traffic from the previous road segment from merging into the next congested road segment.

[0043] In detail, the four-way traffic signal indicator 3 includes traffic signal display screens 36 facing each intersection, traffic diversion switch screens 35 on both sides of the traffic signal display screens 36, diversion directional markings on the traffic signal display screens 36 corresponding to each lane 7, and the diversion directional markings on the traffic signal display screens 36 corresponding to each lane 7 are divided into three directions. The traffic signal display screens 36 are divided into daily guidance mode and diversion guidance mode, and the traffic diversion switch screens 35 are used to display the activation status of the daily guidance mode and the diversion guidance mode.

[0044] ① If a red light is displayed on the traffic diversion switch screen 35, it means that the diversion guidance state of the traffic signal indicator screen 36 is not enabled, and the normal guidance state is used and the diversion guidance state is disabled.

[0045] ② If a green light is displayed on the traffic diversion switch screen 35, it means that the diversion guidance state of the traffic signal indicator screen 36 is in use and the daily guidance state is disabled.

[0046] Lane 7 here can be driven according to the direction indicated by the three-way indicator. The three-way indicator can guide vehicles in a lane in three directions at the same time, or multiple three-way indicator signs can be used to guide multiple lanes in a single direction. The guidance and diversion method can be flexibly changed as needed.

[0047] The traffic diversion switch screen 35 is equipped with a status switching countdown module.

[0048] Preferably, the indicator light column 4 is provided with several annular mounting grooves 41, and the four-way traffic signal indicator light 3 is fixed in the annular mounting groove 41 through the mounting connection part 42. One end of the mounting connection part 42 is provided with a plug-in connection groove 421, and both ends of the plug-in connection groove 421 are provided with clamping rubber 422. The annular mounting groove 41 is provided with a fixing groove 423, and the fixing groove 423 is provided with several fixing connection holes 424. A wire hole 425 is provided between the fixing connection holes 424.

[0049] Specifically, the annular mounting groove 41 is provided with annular fixing brackets 411 on the upper and lower sides. The annular fixing brackets 411 are provided with a plurality of positioning holes 412 around the circumference. The mounting connection part 42 is provided with a fixing connection part 426 at the end away from the insertion connection groove 421. The fixing connection part 426 is provided with a connecting through hole 427. The fixing connection part 426 and the connecting through hole 427 are provided with a plurality of mounting holes 428 corresponding to the positioning holes 412 around the circumference.

[0050] More specifically, the sliding protective structure 5 includes a sliding sleeve 51 disposed on the inner side of the indicator light column 4. A sliding connecting cylinder 52 is slidably disposed inside the sliding sleeve 51. A driving cylinder 53 for driving the sliding connecting cylinder 52 and the sliding sleeve 51 to move is disposed at the bottom of the indicator light column 4. An elastic telescopic tarpaulin 54 is disposed on the top of the sliding connecting cylinder 52. The elastic telescopic tarpaulin 54 is stored in the upper end of the sliding sleeve 51. When the sliding connecting cylinder 52 drives the elastic telescopic tarpaulin 54 to slide out of the sliding sleeve 51, the elastic telescopic tarpaulin 54 automatically extends. When the sliding connecting cylinder 52 drives the elastic telescopic tarpaulin 54 to slide into the sliding sleeve 51, the elastic telescopic tarpaulin 54 automatically retracts.

[0051] The indicator light column 4 has an arc-shaped limiting ring on its inner wall, and the bottom of the sliding sleeve 51 has an arc-shaped limiting ring corresponding to the limiting ring. When the sliding sleeve 51 is limited, the sliding connecting cylinder 52 is driven by the driving cylinder 53 to continue to slide upward, so that the elastic telescopic tarpaulin 54 is freed from the limitation of the sliding sleeve 51 and extends. The upper inner side of the sliding sleeve 51 has a groove for the sliding connecting cylinder 52 to slide.

[0052] In addition, the sliding solar module 6 includes a solar panel 61 with the indicator light column 4 facing south. The lower back of the solar panel 61 is provided with an automatic retraction rod 62 and the upper side is provided with an elastic connector 63. One end of the elastic connector 63 is connected to the sliding sleeve 51. The automatic retraction rod 62 is slidably connected to the reinforcing rib 64 provided at the bottom of the indicator light column 4. The inclined surface of the reinforcing rib 64 is provided with a sliding connection groove 65 into which the automatic retraction rod 62 can be inserted.

[0053] The bottom of the indicator light column 4 has an independent power supply module, which is connected to the power supply via a cable, and can be switched between solar power supply and cable power supply via a switch.

[0054] When the drive cylinder 53 drives the sliding connecting cylinder 52 to rise and fall, the solar panel 61 slides in conjunction. In rainy or snowy weather, the elastic telescopic tarpaulin 54 unfolds, and the solar panel 61 is in a vertical, off-duty state. In sunny weather, the elastic telescopic tarpaulin 54 retracts, and the solar panel 61 is in a tilted, usable state.

[0055] Furthermore, a sliding groove 66 is provided on one side of the indicator light column 4. The sliding groove 66 is connected to the sliding connecting groove 65. The upper part of the sliding groove 66 is the sliding groove 66, and the lower end is the closed groove.

[0056] Furthermore, the multi-directional lane guide line 8 includes a left-turn guide line 81, a right-turn guide line 82, and a straight-ahead guide line 83. The multi-directional lane guide line 8 uses light strips for guidance. The front end of the lane 7 is provided with a slow-moving yielding waiting area 71, and the lane 7 is provided with yielding reversing lanes 72 on both sides.

[0057] A method for guiding traffic flow diversion at urban intersections:

[0058] S1. Real-time monitoring of traffic flow in the next road segment is conducted through a traffic flow monitoring agency (1);

[0059] S2. When a lane or the entire road segment is about to become congested, the traffic light control platform 2 adjusts the four-way traffic signal indicator 3 of the previous road segment.

[0060] S3. Traffic flow in the lanes of the previous road segment merges into other road segments and is diverted according to the guidance of the multi-directional lane guide line 8 and the four-way traffic signal indicator 3.

[0061] In summary, the principle of this embodiment is as follows: the traffic flow monitoring mechanism 1 monitors the traffic flow of the next road segment in real time. When a lane or the entire road segment of the next segment is about to become congested, the traffic light control platform 2 adjusts the four-way traffic signal indicator 3 of the previous road segment to divert the traffic flow in the lane of the previous road segment to other road segments, thus avoiding merging into the soon-to-be-congested road segment. Secondly, the sliding solar panel 6 is linked with the sliding protective structure. In sunny weather, the solar panel 61 is activated and the elastic telescopic tarpaulin 54 is retracted. In rainy or snowy weather, the solar panel 61 is retracted and the elastic telescopic tarpaulin 54 is unfolded, which can effectively prevent damage to the four-way traffic signal indicator.

[0062] This application can also adjust the traffic flow of the current road segment in real time, or monitor the traffic flow of the previous road segment to guide the traffic flow of the next road segment in advance, so as to quickly clear the lanes and allow the congested traffic flow of the previous road segment to quickly merge in.
