Description

Technical Field

[0001] This invention relates to the field of intelligent transportation vehicle-road cooperative technology, specifically to a sign management optimization system and method. Background Technology

[0002] With the rapid development of communication technology, control technology, and sensors, the intelligentization of vehicles and roads has been promoted. Intelligent connected vehicles refer to vehicles equipped with advanced on-board sensors, controllers, actuators, and other devices, and integrated with modern communication and network technologies to realize intelligent information exchange and sharing between vehicles, roads, people, and cloud nodes. This enables vehicles to have functions such as complex environment perception, intelligent decision-making, and collaborative control, and can achieve safe, efficient, comfortable, and energy-saving driving.

[0003] ITS (Intelligent Transportation Systems) vehicle communication systems utilize advanced wireless communication technology to create intelligent transportation sensor networks that enable information exchange between vehicles, road infrastructure, other vehicles, and pedestrians. This system fills the gap in vehicle communication capabilities within transportation systems, allowing vehicles to perceive the road environment, and enabling pedestrians and control centers to perceive vehicle operating status. This improves traffic management, enhances driving safety, and achieves energy conservation and emission reduction.

[0004] Traditional traffic signs are directional signs supported by pillars and mounted above the side of the road. Types of signs include warning signs, prohibitory signs, instruction signs, and guide signs. These signs provide important information to road users with their simple and clear graphics and text. However, the limitations of traditional traffic signs are also obvious: they can only present information in a fixed way and cannot be adjusted according to real-time traffic conditions. In complex traffic environments, this fixed method of instruction can sometimes confuse drivers, making it difficult for them to accurately identify the sign information.

[0005] Vehicle-to-Infrastructure (IVICS) systems are an important component of Intelligent Transportation Systems (ITS). These systems digitize information from roadside equipment such as signs and transmit it directly to vehicles, promoting the development of autonomous driving and improving traffic management. It is foreseeable that future transportation systems will not only include vehicle intelligence but also encompass the development of vehicle-to-infrastructure cooperation.

[0006] There are many types of signs; a single road may have multiple different types of signs, and signs may also differ between different roads. Furthermore, traffic authorities may issue temporary signs based on actual conditions or emergencies, such as road construction, traffic congestion, and weather changes. Given the complexity of sign information, its management is particularly important to ensure the accuracy and timeliness of the information displayed. Summary of the Invention

[0007] The purpose of this invention is to propose a sign management optimization system and method. This technical solution can optimize sign management and ensure the accuracy and timeliness of sign information.

[0008] To achieve the above objectives, in a first aspect, embodiments of this disclosure provide a signage management optimization system, comprising:

[0009] The sign creation module is used to add sign information and signage impact path information. Sign information includes sign type, sign name, signage location information, radius of effect, application scenario, and effective time. It is also used to filter associated devices based on signage location information, radius of effect, impact path, and application scenario, generate sign illustrations based on sign type and sign name, and generate release strategies based on effective time.

[0010] The sign management module is used to dynamically and continuously broadcast the current sign release status, provide global reminders for the latest signs, and also to query and edit signs.

[0011] Beneficial effects of the basic solution: This technical solution generates sign illustrations by using sign type and sign name, ensuring the accuracy of the generated sign illustrations. By filtering associated devices based on sign location information, radius of influence, path of influence, and application scenario, it ensures that the signs are published in the correct area of ​​influence. Combined with the generated publishing strategy, it ensures the accuracy of the sign information. At the same time, selecting effective associated devices for publishing also ensures the real-time nature of the sign information.

[0012] The sign management module can broadcast and remind managers of the status of signs, making it easier for them to understand the current sign conditions and verify the accuracy of the sign information. At the same time, the sign management module can also edit the sign information and correct any errors in a timely manner, further ensuring the accuracy of the sign information.

[0013] As a preferred embodiment, the marker creation module selects the start and end positions of the path through a graphical editor, obtains, records, and converts them into WGS84 coordinate format in sequence.

[0014] The graphical editor allows for convenient, intuitive, and accurate selection of the start and end points of the path, facilitating editing and verification by administrators. Furthermore, coordinate format conversion ensures information accuracy and consistency, enabling users to share and exchange information across various applications.

[0015] As a preferred embodiment, the equipment management module is used to generate an electronic fence based on the location information, radius of action, and sign influence path information, and to filter associated equipment according to the equipment installation location to form a first equipment list; it is also used to filter associated equipment from the first equipment list to form a second equipment list according to the sign application scenario and the current online status of the equipment; and it is also used to manually filter associated equipment from the second equipment list to form a third equipment list.

[0016] By defining electronic fences, associated devices within the sign's effective area can be quickly and accurately identified, forming a first device list. Further filtering yields a second device list, ensuring the effectiveness of sign placement. A third device list allows for the selection and deployment of devices based on special circumstances or actual situations. This multi-layered filtering ensures the accuracy and real-time nature of sign placement.

[0017] As a preferred embodiment, the logo management module monitors the publishing status of the logo creation module in real time and triggers a global reminder when there is a new publishing event in the logo publishing submodule.

[0018] This technical solution can provide real-time alerts for the release of new signs, facilitating the verification of information such as the type, name, and effective date of the signs, thus ensuring their accuracy.

[0019] As a preferred embodiment, the sign management module is used to query the distribution of currently valid signs, and also to retrieve signs based on sign information or retrieve sign information based on signs.

[0020] This technical solution enables a quick understanding of the status of published signs, while the two-way search also facilitates rapid searching and management of signs from multiple perspectives.

[0021] As a preferred embodiment, the logo management module is also used to query the logo information history and can directly import the queried history into the logo creation module.

[0022] When creating a previously created sign, the sign creation module can directly import historical records through the sign record submodule, improving the efficiency of sign creation. It can also ensure the real-time release of signs when there is an urgent need to release some signs. At the same time, since most sign information uses historically effective sign information, there is no need to add them again, which also ensures the accuracy of the signs.

[0023] As a preferred embodiment, the sign management module is also used to display the sign history in a list format and to edit one or more existing signs. Editing operations include canceling signs, deleting history records, and clearing sign content.

[0024] This technical solution allows for the editing of signs, facilitating timely corrections when errors occur. It also enables the organization of sign history records, making sign management and optimization easier.

[0025] As a preferred option, the sign management module sets reminder priorities for different sign information based on actual conditions.

[0026] It can prioritize displaying important reminders during busy or emergency situations, thus facilitating more effective management of a large number of notification messages.

[0027] Secondly, this disclosure provides a sign management optimization method, which utilizes a sign management optimization system. Attached Figure Description

[0028] Figure 1 This is a structural diagram of the signage management optimization system. Detailed Implementation

[0029] The technical solution of this application will be further described in detail below through specific embodiments:

[0030] In the description of this invention, it should be noted that the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0031] Example 1

[0032] Reference Figure 1 The signage management optimization system includes:

[0033] The logo creation module includes an information addition submodule, a path management submodule, a device management submodule, and a logo publishing submodule.

[0034] The information addition submodule is used to add sign information, which includes, but is not limited to, sign type, sign name, sign location information, radius of effect, application scenario, and effective time.

[0035] The path management submodule is used to add information about the impact of signs on the path. Using a graphical editor, users can select the start and end points of the impact path. The graphical editor runs on the map page, providing users with an intuitive and real-time map display. It supports selecting the start and end points on the map page and can also obtain the coordinate information of the selected points.

[0036] After selection, the map page displays the added impact path points and line segment information, as well as a diagram of the equipment locations along the path. This information display method is very intuitive, allowing users to clearly see the direction of the impact path and each key point. The map page supports zooming to full-screen display. After addition, the impact path point information edited by the path management submodule is saved, recorded sequentially, and converted to WGS84 coordinate format to ensure the accuracy and consistency of the information, facilitating information sharing and exchange in various applications.

[0037] The equipment management submodule requires that sign information dissemination be completed through associated devices. Associated devices include in-vehicle communication equipment and roadside equipment. In-vehicle communication equipment communicates with intelligent connected vehicles, sending sign information to the in-vehicle terminal to alert the driver or provide sign information reference for the autonomous driving (cruise) system. Roadside equipment can utilize intelligent traffic signs, and sign information can be directly displayed in the scene or accompanied by corresponding voice prompts through the roadside terminal.

[0038] The equipment management submodule first generates an electronic fence based on information such as the location of the action point, the radius of action, and the influence path information of the sign. The electronic fence can be rectangular, circular, or an irregular shape. It then filters and associates equipment according to the equipment installation location, forming a first equipment list. This list contains various information about the equipment, including its model and functional status.

[0039] The equipment management submodule is also used to filter associated equipment information based on the application scenario of the sign and the current online status of the equipment. For example, when the sign contains route indication information, the associated equipment information at the intersection is filtered and added to the equipment list; when the sign contains road construction information, the associated equipment near the construction site is filtered and added to the equipment list, forming a second equipment list.

[0040] The equipment management submodule also supports manual filtering of associated equipment, allowing you to manually filter the associated equipment in the second equipment list to create a third equipment list. The first, second, and third equipment lists all include the parameters of the equipment's issuing sign.

[0041] The logo publishing submodule is used to generate logo illustrations based on logo type and logo name, parse the published logo information reported by the current device based on the second or third device list and the device adaptation protocol corresponding to each device on the device list, insert the currently published logo information, and generate a distribution message.

[0042] The sign publishing submodule is also used to generate sign publishing strategies, that is, to adjust the frequency and timing of sign information publishing based on actual conditions. For example, the sign information for tidal flow lanes can be set to be published only when the tidal flow lane is in effect.

[0043] The flag management module includes a dynamic broadcast submodule, a global reminder submodule, a flag query submodule, and a flag record submodule.

[0044] The dynamic broadcast submodule is used to dynamically and continuously broadcast the current signage status, providing a real-time, efficient, and convenient work dashboard. This submodule can deliver signage status updates to administrators through various channels such as email, SMS, and mobile application push notifications.

[0045] The global alert submodule is used to provide global alerts for the latest pushed signs, supporting visual display. In one embodiment, a map area is used for display. The global alert submodule monitors the publishing status of the sign publishing submodule in real time and triggers an alert when the sign publishing submodule has a new publishing event.

[0046] The sign query submodule is used to query the distribution of currently valid warning signs, prohibitory signs, instruction signs, and directional signs. This submodule can also be used to retrieve sign information based on the sign itself, or to retrieve signs based on sign information.

[0047] The Sign Records submodule displays a list of sign history records. It allows users to view an overview of currently active signs, show sign locations, and edit existing signs, including canceling signs, deleting records, and clearing sign content. These operations can be performed on a single sign or in batches on multiple signs. The Sign Records submodule also supports historical record queries. When creating a previously created sign using the Information Addition submodule, users can directly import historical records through the Sign Records submodule. Furthermore, the Sign Records submodule supports exporting sign records as reports, charts, or other formats for further analysis and use.

[0048] This embodiment also provides a sign management optimization method, which utilizes the aforementioned system.

[0049] This embodiment also includes a storage medium storing a computer program, which, when executed by a processor, implements a sign management optimization method.

[0050] Example 2

[0051] The global alert submodule allows you to set alert priorities for different types of flag information, ensuring that important alerts are displayed first during busy or emergency situations. The global alert submodule sets priority weights based on flag type; timeliness priority weights based on the real-time nature and duration of flag release (e.g., newly released flags with short durations have higher priority than those with consistently high durations); and range priority weights based on the area of ​​the flag's geofence, prioritizing flags with a larger impact area. The global alert submodule assigns the first priority to each released flag based on these priority weights, facilitating more effective management of a large number of flag messages.

[0052] The sign publishing submodule will also set a priority weight value for sign effectiveness based on the vehicles' compliance with the published sign information. This will increase the priority of sign information with poor compliance and combine it with the first priority to obtain a second priority, which will be used to optimize the priority of sign publishing, thereby enabling drivers to obtain sign information more effectively.

[0053] The sign publishing submodule will also generate priority correction values ​​based on real-time traffic conditions within the electronic fence area of ​​the sign information. This will adjust the priority of sign information of the directional sign type, and further adjust the priority of directional sign information arriving at the affected path based on traffic flow conditions along that path within the electronic fence. Specifically, if traffic congestion occurs on the affected path, the priority correction value will be lowered; if traffic flow is low, the priority will be increased; and if traffic flow is normal, the priority will remain unchanged. This achieves real-time guidance of traffic to avoid congested sections and intelligent traffic management.

[0054] This embodiment also provides a sign management optimization method, which utilizes the aforementioned system.

[0055] This embodiment also provides a storage medium storing a computer program, which, when executed by a processor, implements a sign management optimization method.

[0056] Those skilled in the art will understand that implementing all or part of the processes in a signage management optimization method can be accomplished by a computer program instructing related hardware. The program can be stored in a non-volatile computer-readable storage medium. When executed, the program can include the processes of various embodiments of the signage management optimization method.
