Description

Technical Field

[0001] This invention relates to the field of vehicle driving technology, and specifically to a road traffic control method, device, and system. Background Technology

[0002] In urban traffic management systems, traffic control is an important means of ensuring road traffic safety and smooth flow in response to special circumstances such as traffic accidents, road construction, or large-scale events. In related technologies, it is necessary to wait for traffic police to arrive at the traffic control section and complete a series of manual operations such as placing traffic control objects like traffic cones before traffic control can begin. This results in low timeliness of traffic control. Therefore, how to improve the timeliness of traffic control has become a problem that needs to be solved. Summary of the Invention

[0003] In view of this, the present invention provides a road traffic control method, apparatus and system to solve the problem of low timeliness of traffic control.

[0004] In a first aspect, the present invention provides a road traffic control method applied to an intelligent traffic control platform. The method includes: generating traffic control description information for a target vehicle based on received traffic control configuration information of a target controlled road segment, wherein the traffic control description information describes the traffic control implemented on the target controlled road segment and includes traffic elements involved in the traffic control implemented on the target controlled road segment; and sending the traffic control description information to the target vehicle to display the control information on the target vehicle, wherein the control information is used to remind the driver of the target vehicle to drive the vehicle according to the traffic control description information when the target vehicle is on the target controlled road segment.

[0005] The road traffic control method provided by this invention involves an intelligent traffic control platform generating traffic control description information for target vehicles based on the received traffic control configuration information of the target controlled road segment. This description information includes the traffic elements involved in traffic control on the target controlled road segment. The traffic control description information is then sent to the target vehicles for display, reminding the drivers to follow the description information when the vehicles are on the target controlled road segment. This allows the intelligent traffic control platform to automatically implement traffic control based on the traffic control configuration information set by traffic police lines, eliminating the need for police personnel to be present, thus saving manpower costs. It also eliminates the need to wait for traffic police to arrive at the controlled road segment and for manual operations such as placing traffic cones, resulting in high efficiency. Furthermore, the traffic control configuration information can be adjusted at any time to modify the traffic control method, improving the flexibility of traffic control. The traffic control is independent of the presence of roadside equipment, making it highly applicable.

[0006] In one optional implementation, the traffic control configuration information further includes at least traffic control configuration information corresponding to different vehicle types set for the current traffic control scenario, wherein the vehicle type is reported by the vehicle to the intelligent traffic control platform, and the step of generating traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road segment includes: generating traffic control description information of the vehicle type to which the target vehicle belongs based on the received traffic control configuration information of the target controlled road segment.

[0007] This invention can generate corresponding traffic control description information for different vehicle types based on traffic control configuration information set for different traffic control scenarios and different vehicle types, and distribute it to the corresponding types of vehicles. This enables different traffic control measures to be taken for different types of vehicles, avoiding the current situation where traffic police can only find target vehicles by sight and guide them through traffic flow, as well as the difficulties in guidance and missed checks caused by the current situation.

[0008] In one optional implementation, the traffic control configuration information further includes configuration information for a fixed time period. The step of generating traffic control description information for the target vehicle based on the received traffic control configuration information for the target controlled road segment includes: when the current time is within the fixed time period, generating traffic control description information for the target vehicle based on the received traffic control configuration information for the target controlled road segment.

[0009] This invention sets up corresponding timed automatic control for road sections that require long-term control, achieving precise adaptation of time-based control, avoiding delays caused by manual operation and reducing repetitive manual control.

[0010] In one optional implementation, generating traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road segment includes: when the traffic control scenario in the traffic control configuration information corresponding to the fixed time period is a traffic congestion scenario and the vehicle density corresponding to the target controlled road segment is greater than a preset density threshold, generating traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road segment, wherein the vehicle density corresponding to the target controlled road segment is calculated based on the spatial range of the target controlled road segment and real-time vehicle data.

[0011] This invention only implements traffic control when actual congestion is detected on the target controlled road section, thereby achieving precise management of congestion problems, avoiding waste of traffic management resources, improving the efficiency and effectiveness of traffic management, and avoiding unnecessary traffic control when traffic conditions are normal, thus reducing interference with normal traffic order.

[0012] In one optional implementation, the intelligent traffic control platform and vehicles interact via a vehicle-to-everything (V2X) network. The traffic control configuration information includes at least channelization length, lane layout information, and traffic light configuration information. The step of generating traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road segment includes: generating static road structure information and vehicle trajectory standards conforming to V2X standards based on the lane layout information and channelization length; and generating virtual traffic light equipment and corresponding dynamic signal timing information conforming to V2X standards based on the traffic light configuration information of the target controlled road segment.

[0013] In an optional implementation, the method further includes: comparing the target vehicle trajectory on the target controlled road segment with the traffic control description information to obtain a judgment result indicating whether the target vehicle is driving in accordance with the traffic control description information when on the target controlled road segment; if the judgment result indicates that the target vehicle is not driving in accordance with the traffic control description information when on the target controlled road segment, performing corresponding abnormal driving processing on the target vehicle.

[0014] This invention can compare the driving trajectory of a target vehicle with traffic control description information, and can promptly and accurately determine whether the target vehicle is driving illegally and take appropriate action. By handling vehicles driving abnormally, dangerous behaviors can be corrected in a timely manner, reducing the probability of traffic accidents and protecting the lives and property of all participants on the road.

[0015] In an optional implementation, the method further includes: if there are roadside devices in the target controlled road segment that can perform traffic control, sending traffic control configuration information to the road traffic signal controller in the roadside device.

[0016] Secondly, the present invention provides a road traffic control device applied to an intelligent traffic control platform. The device includes: a traffic control generation module, used to generate traffic control description information for a target vehicle based on received traffic control configuration information of a target controlled road segment. The traffic control description information describes the traffic control implemented on the target controlled road segment and includes traffic elements involved in the traffic control implemented on the target controlled road segment; and a traffic control distribution module, used to distribute the traffic control description information to the target vehicle to display the control information on the target vehicle. The control information is used to remind the driver of the target vehicle to drive the vehicle according to the traffic control description information when the target vehicle is on the target controlled road segment.

[0017] Thirdly, the present invention provides a road traffic control system, the system including an intelligent traffic control platform, the intelligent traffic control platform including a controller, the controller including a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the road traffic control method of the first aspect or any corresponding embodiment described above.

[0018] In one optional implementation, the system further includes roadside equipment for receiving traffic control configuration information sent by the intelligent traffic control platform when it is operating normally, and for implementing traffic control on target vehicles based on the traffic control configuration information.

[0019] The road traffic control method provided by this invention involves an intelligent traffic control platform generating traffic control description information for target vehicles based on the received traffic control configuration information of the target controlled road segment. This description information includes the traffic elements involved in traffic control on the target controlled road segment. The traffic control description information is then sent to the target vehicles for display, reminding the drivers to follow the description information when the vehicles are on the target controlled road segment. This allows the intelligent traffic control platform to automatically implement traffic control based on the traffic control configuration information set by traffic police lines, eliminating the need for police personnel to be present, thus saving manpower costs. It also eliminates the need to wait for traffic police to arrive at the controlled road segment and for manual operations such as placing traffic cones, resulting in high efficiency. Furthermore, the traffic control configuration information can be adjusted at any time to modify the traffic control method, improving the flexibility of traffic control. The traffic control is independent of the presence of roadside equipment, making it highly applicable. Attached Figure Description

[0028] 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] With the development of autonomous driving, the single-vehicle intelligence route and the vehicle-road-cloud route are showing a trend of integration. The development of single-vehicle intelligence is much faster than that of vehicle-road-cloud because vehicle-road-cloud relies on the deployment of equipment, which is very costly. The numerous data sources of vehicle-road-cloud are both its advantage and disadvantage. The data sources are difficult to coordinate and be consistent, and the authenticity, legality and timeliness of the data are difficult to guarantee. In addition, the current deployment rate of roadside equipment is low, and the cost of adding equipment at non-intersections is huge.

[0030] According to an embodiment of the present invention, a road traffic control method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] This embodiment provides a road traffic control method that can be used in an intelligent traffic control platform. The intelligent traffic control platform is configured geographically and utilizes regional edge clouds to ensure data real-time performance. The platform type and specific module composition of the intelligent traffic control platform are not limited, as long as they can execute the road traffic control method. Figure 1As shown, the intelligent traffic control platform designed in this embodiment of the invention can be divided into a road traffic center signal control platform and a traffic control platform. The road traffic center signal control platform provides users (i.e., traffic police and other road workers) with a platform to set traffic control configuration information, so that users can submit traffic control configuration information, such as traffic lights, road information (e.g., construction, accidents, road unevenness, and number of lanes), based on their current traffic control needs for a certain road segment. The data source comes from the road traffic center signal control platform to ensure the authenticity and legality of the data. The traffic control platform can interact with the road traffic center signal control platform to generate traffic control description information based on the traffic control configuration information sent by the road traffic center signal control platform, and establish a network connection with vehicles to realize the distribution of traffic control description information and the receipt of vehicle driving information reported by vehicles. The vehicles are vehicles with positioning, network connectivity, and traffic control software installed.

[0032] Figure 2 This is a flowchart of a road traffic control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0033] Step S201: Based on the received traffic control configuration information of the target controlled road segment, generate traffic control description information for the target vehicle.

[0034] The traffic control description information is used to describe the traffic control measures implemented on the target controlled road segment. The traffic control description information includes the traffic elements involved in the traffic control measures implemented on the target controlled road segment.

[0035] In this embodiment of the invention, when users (i.e., traffic police and other road workers) determine that traffic control is required on a target controlled road segment, they can directly set traffic control configuration information for the target controlled road segment through the intelligent traffic control platform. This traffic control configuration information may include, but is not limited to, the target controlled road segment, traffic lights, number of lanes, and road information (such as construction, accidents, uneven roads). As an example, the intelligent traffic control platform can generate traffic control description information for a target vehicle based on the received traffic control configuration information for the target controlled road segment. The target vehicle is the vehicle traveling on the target controlled road segment. The traffic control description information may include traffic elements involved in the traffic control implemented on the target controlled road segment, such as lane layout for the target vehicle and dynamic display of traffic lights (e.g., traffic light data is cyclical, so configuring the number of seconds for each state can simulate this; for example, configuring lane 1 with a red light of 30 seconds). If a green light lasts 10 seconds and a yellow light lasts 3 seconds, then the data for the next 3 seconds will be as follows: Lane 1, green light 10 seconds, lane 1, green light 9 seconds, lane 1, green light 8 seconds, then yellow light, red light, and then cycle back to green light, etc. This embodiment of the invention does not limit the method of generating traffic control description information for target vehicles based on traffic control configuration information. For example, the intelligent traffic control platform can generate corresponding virtual lane-level traffic lights, road layouts, and other traffic control description information based on traffic control configuration information. That is, it collects static and dynamic road data from traffic control configuration information, performs virtual road modeling and traffic light dynamic data modeling, and builds a virtual lane-level scene as traffic control description information. This is just an example; it enables lane control through lane and traffic light description information, eliminating the need for traffic cones and the limitations imposed by their placement. Furthermore, vehicles do not need to forcibly change lanes multiple times to compete for the open lane, reducing the risk of accidents.

[0036] Step S202: Send the traffic control description information to the target vehicle so that the control information can be displayed on the target vehicle.

[0037] Among them, the traffic control information is used to remind the driver of the target vehicle to drive the vehicle in accordance with the traffic control description information when the target vehicle is on the target controlled road section.

[0038] The intelligent traffic control platform of this invention can send the generated traffic control description information to the target vehicle, and the target vehicle can display the control information, such as... Figure 3 The example shown illustrates the traffic control measures displayed to the driver, who can then drive the vehicle according to the traffic control description information when driving on the target controlled road segment.

[0039] The road traffic control method provided by this invention involves an intelligent traffic control platform generating traffic control description information for target vehicles based on the received traffic control configuration information of the target controlled road segment. This description information includes the traffic elements involved in traffic control on the target controlled road segment. The traffic control description information is then sent to the target vehicles for display, reminding the drivers to follow the description information when the vehicles are on the target controlled road segment. This allows the intelligent traffic control platform to automatically implement traffic control based on the traffic control configuration information set by traffic police lines, eliminating the need for police personnel to be present, thus saving manpower costs. It also eliminates the need to wait for traffic police to arrive at the controlled road segment and for manual operations such as placing traffic cones, resulting in high efficiency. Furthermore, the traffic control configuration information can be adjusted at any time to modify the traffic control method, improving the flexibility of traffic control. The traffic control is independent of the presence of roadside equipment, making it highly applicable.

[0040] This embodiment provides a road traffic control method that can be used in an intelligent traffic control platform. Figure 4 This is a flowchart of a road traffic control method according to an embodiment of the present invention, such as... Figure 4 As shown, the flowchart includes the following steps:

[0041] Step S401: Based on the received traffic control configuration information of the target controlled road segment, generate traffic control description information for the target vehicle.

[0042] The traffic control description information is used to describe the traffic control measures implemented on the target controlled road segment. The traffic control description information includes the traffic elements involved in the traffic control measures implemented on the target controlled road segment.

[0043] Specifically, the intelligent traffic control platform and vehicles exchange information via the Internet of Vehicles. The traffic control configuration information includes at least channelization length, lane layout information, and traffic light configuration information. Step S401 includes:

[0044] Step S4011: Based on lane layout information and channelization length, generate static road structure information and vehicle trajectory standards that conform to the Internet of Vehicles standard.

[0045] Step S4012: Based on the traffic light configuration information of the target controlled road section, generate virtual traffic light equipment and corresponding dynamic signal timing information that conforms to the Internet of Vehicles standard.

[0046] like Figure 1As shown, the traffic control platform of this embodiment of the invention can interact with vehicles through a vehicle-to-everything (V2X) service platform. The traffic control configuration information includes at least the channelization length set by traffic police (by setting the channelization length, i.e., setting a no-lane-changing zone, vehicles can be guided to change lanes in advance and queue), lane layout information, and traffic light configuration information. Based on the lane layout information and channelization length, the intelligent traffic control platform can generate static road structure MAP information and vehicle trajectory standards that conform to the V2X standard. The vehicle trajectory standard is used to determine whether a vehicle has changed lanes illegally. It can also generate virtual traffic light equipment according to the traffic light configuration information of the target controlled road section, determine the traffic light data according to the equipment operation logic, generate dynamic signal timing SPAT information that conforms to the V2X standard, and finally send the corresponding V2X MAP SPAT message to the target vehicle.

[0047] In one optional implementation, traffic control description information of the target vehicle's type is generated based on the received traffic control configuration information of the target controlled road segment. The traffic control configuration information includes at least traffic control configuration information corresponding to different vehicle types set for the current traffic control scenario. The vehicle type is reported by the vehicle to the intelligent traffic control platform.

[0048] This invention allows for the setting of corresponding traffic control configuration information for different traffic control scenarios and vehicle types. These scenarios may include, but are not limited to, vehicle checks, traffic control, priority passage for special vehicles, and traffic accidents. Taking a four-lane road as an example, for traffic control scenarios... Figure 3 As shown, based on the configured number of lanes and red light duration, lanes ①, ②, ③, and ④ can be released in turn, with the released lanes displaying a green light and the other lanes displaying a red light. For different vehicle types corresponding to vehicle inspection scenarios, including the vehicle being inspected and other vehicle types, the traffic control configuration information for the vehicle being inspected can be set as follows: lanes ①, ②, and ③ are red, and lane ④ is flashing yellow, guiding the inspected vehicle to queue in lane ④ for inspection. For other vehicle types, the configuration information for lanes ①, ②, and ③ is set to green. For priority passage scenarios for special vehicles, including special vehicle types and other vehicle types, the traffic control configuration information for special vehicle types can be set as follows: lane ① is dark green, and lanes ②, ③, and ④ are green. For other vehicle types, lane ① is set to red, and lanes ②, ③, and ④ are set to green. This is just an example.

[0049] According to the traffic control configuration information corresponding to different vehicle types in the current traffic control scenario, the intelligent traffic control platform of this invention can generate traffic control description information corresponding to the vehicle type of the target vehicle, and then send the traffic control description information corresponding to the vehicle type to the target vehicle.

[0050] This invention can generate corresponding traffic control description information for different vehicle types based on traffic control configuration information set for different traffic control scenarios and different vehicle types, and distribute it to the corresponding types of vehicles. This enables different traffic control measures to be taken for different types of vehicles, avoiding the current situation where traffic police can only find target vehicles by sight and guide them through traffic flow, as well as the difficulties in guidance and missed checks caused by the current situation.

[0051] In some optional implementations, the traffic control configuration information may also include configuration information for a fixed time period. Generating traffic control description information for the target vehicle based on the received traffic control configuration information for the target controlled road segment includes: when the current time is within a fixed time period, generating traffic control description information for the target vehicle based on the received traffic control configuration information for the target controlled road segment.

[0052] Traffic control in this invention can be divided into temporary control and timed automatic control. For scenarios such as traffic accidents and vehicle checks, traffic police can use vehicle-mounted devices or handheld mobile devices to perform temporary control only once. The intelligent control platform is online, and the two can connect and interact if the handheld device has the necessary permissions. The form can be a webpage, an APP, etc. As an example, traffic police can upload traffic control configuration information of the target controlled road section to the intelligent traffic control platform through the handheld device. Then, the intelligent traffic control platform can generate traffic control description information and send it to the target vehicle.

[0053] This invention can set up corresponding timed automatic control for road sections that require long-term control. For example, for road sections with long-term congestion, traffic control can be implemented according to the configured peak hours. Traffic police can set fixed time period configuration information in the traffic control configuration information. When the current time is within a fixed time period, the intelligent traffic control platform can generate traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road section, thereby realizing automatic control.

[0054] This invention sets up corresponding timed automatic control for road sections that require long-term control, achieving precise adaptation of time-based control, avoiding delays caused by manual operation and reducing repetitive manual control.

[0055] In one optional implementation, when the traffic control scenario in the traffic control configuration information corresponding to a fixed time period is a traffic congestion scenario and the vehicle density corresponding to the target controlled road segment is greater than a preset density threshold, traffic control description information for the target vehicle is generated based on the received traffic control configuration information of the target controlled road segment. The vehicle density corresponding to the target controlled road segment is calculated based on the spatial range of the target controlled road segment and real-time vehicle data.

[0056] In this embodiment of the invention, vehicles report their location information to the intelligent traffic control platform in real time. Based on the congestion situation of the target controlled road segment, the intelligent traffic control platform can obtain the spatial range (such as the length of the road segment) and real-time vehicle data of the target controlled road segment before automatic control is implemented. It can also calculate the vehicle density on the target controlled road segment and determine whether the vehicle density is greater than a preset density threshold. If the vehicle density is greater than the preset density threshold, it indicates that there is congestion on the target controlled road segment. Then, based on the traffic control configuration information of the target controlled road segment, it can generate traffic control description information for the target vehicle to execute traffic control. If the vehicle density is not greater than the preset density threshold, it indicates that there is no congestion on the target controlled road segment, and traffic control can be omitted.

[0057] This invention only implements traffic control when actual congestion is detected on the target controlled road section, thereby achieving precise management of congestion problems, avoiding waste of traffic management resources, improving the efficiency and effectiveness of traffic management, and avoiding unnecessary traffic control when traffic conditions are normal, thus reducing interference with normal traffic order.

[0058] Step S402: Traffic control description information is sent to the target vehicle to display the control information on the target vehicle. The control information serves as a reminder to the driver of the target vehicle to drive according to the traffic control description information when the target vehicle is on the target controlled road section. For detailed explanation, please refer to the above embodiment; it will not be repeated here.

[0059] In one optional implementation, the trajectory of the target vehicle on the target controlled road segment is compared with the traffic control description information to obtain a judgment result indicating whether the target vehicle is driving in accordance with the traffic control description information when it is on the target controlled road segment; if the judgment result indicates that the target vehicle is not driving in accordance with the traffic control description information when it is on the target controlled road segment, the target vehicle is subjected to corresponding abnormal driving processing.

[0060] like Figure 1 As shown, in this embodiment of the invention, the target vehicle can report its location information to the traffic control platform in real time. The traffic control platform filters and generates the target vehicle's trajectory based on the reported location information. This trajectory can be compared with the traffic control description information to obtain a judgment result indicating whether the target vehicle is driving in accordance with the traffic control description information when it is on the target controlled road segment. For example, whether the vehicle ran a red light or illegally changed lanes in the channelized area. This is just an example. If the traffic control platform's judgment result indicates that the target vehicle is not driving in accordance with the traffic control description information, the abnormal driving information of the target vehicle corresponding to the traffic control description information can be fed back to the road traffic center signal control platform. The road traffic center signal control platform can then impose corresponding penalties on the target vehicle based on the abnormal driving information.

[0061] This invention can compare the driving trajectory of a target vehicle with traffic control description information, and can promptly and accurately determine whether the target vehicle is driving illegally and take appropriate action. By handling vehicles driving abnormally, dangerous behaviors can be corrected in a timely manner, reducing the probability of traffic accidents and protecting the lives and property of all participants on the road.

[0062] In one alternative implementation, if there are roadside devices capable of traffic control in the target controlled section, the traffic control configuration information is sent to the road traffic signal controller in the roadside device.

[0063] like Figure 1 As shown, the road traffic control system of this invention includes an intelligent traffic control platform and existing roadside equipment to implement traffic control. When no roadside equipment is detected on the target controlled road segment, traffic control on the target controlled road segment can be implemented through the intelligent traffic control platform. If there is roadside equipment on the target controlled road segment that can perform traffic control, but the roadside equipment is old and lacks network connectivity, the traffic control configuration is sent to the road traffic signal controller in the roadside equipment, and traffic control on the target controlled road segment can be implemented through the intelligent traffic control platform. If there is roadside equipment on the target controlled road segment that can perform traffic control, and the roadside equipment has network connectivity, traffic control can be implemented through the roadside equipment.

[0064] When a target controlled road segment has roadside equipment, traffic control can be achieved through the roadside equipment. When there is no roadside equipment or the roadside equipment does not have network connectivity, traffic control can be achieved through an intelligent traffic control platform. This reduces the vehicle-road-cloud's dependence on roadside equipment, eliminates the need to increase the cost of adding roadside equipment, and provides a virtual data path with authenticity, legality, and timeliness to realize some scenarios with high timeliness requirements of vehicle-road-cloud.

[0065] This embodiment also provides a road traffic control system, such as Figure 5 As shown, the system includes an intelligent traffic control platform, which includes a controller. The controller includes a memory and a processor. The memory and the processor are interconnected. The memory stores computer instructions. The processor executes the computer instructions to perform the road traffic control method described above.

[0066] In one optional implementation, the road traffic control system further includes roadside equipment, used to receive traffic control configuration information sent by the intelligent traffic control platform when operating normally, and to implement traffic control on target vehicles based on the traffic control configuration information, such as... Figure 1 As shown, roadside equipment may include roadside units (RSUs) and road traffic signals.

[0067] This embodiment also provides a road traffic control device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0068] This embodiment provides a road traffic control device applied to an intelligent traffic control platform, such as... Figure 6 As shown, it includes: a traffic control generation module 601, used to generate traffic control description information for a target vehicle based on the received traffic control configuration information of the target controlled road segment. The traffic control description information describes the traffic control implemented on the target controlled road segment and includes the traffic elements involved in the traffic control implemented on the target controlled road segment; and a traffic control distribution module 602, used to distribute the traffic control description information to the target vehicle so that the control information can be displayed on the target vehicle. The control information is used to remind the driver of the target vehicle to drive the vehicle according to the traffic control description information when the target vehicle is on the target controlled road segment.

[0069] In some optional implementations, the traffic control configuration information may include at least the traffic control configuration information corresponding to different vehicle types set for the current traffic control scenario. The vehicle type is reported by the vehicle to the intelligent traffic control platform. The traffic control generation module 601 includes a vehicle type determination unit, which is used to generate traffic control description information of the vehicle type to which the target vehicle belongs based on the traffic control configuration information of the target controlled road segment received.

[0070] In some optional implementations, the traffic control configuration information also includes configuration information for a fixed time period. The traffic control generation module 601 includes a timed traffic control unit, which generates traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road segment when the current time is within a fixed time period.

[0071] In some optional implementations, the traffic control generation module 601 includes: a vehicle density calculation unit, used to generate traffic control description information for the target vehicle based on the received traffic control configuration information of the target controlled road segment when the traffic control scenario in the traffic control configuration information corresponding to a fixed time period is a traffic congestion scenario and the vehicle density corresponding to the target controlled road segment is greater than a preset density threshold. The vehicle density corresponding to the target controlled road segment is calculated based on the spatial range of the target controlled road segment and real-time vehicle data.

[0072] In some optional implementations, the intelligent traffic control platform and vehicles interact via the Internet of Vehicles (IoV). The traffic control configuration information includes at least channelization length, lane layout information, and traffic light configuration information. The traffic control generation module 601 includes: a trajectory standard generation unit, used to generate static road structure information and vehicle driving trajectory standards that conform to the IoV standard based on the lane layout information and channelization length; and a dynamic signal generation unit, used to generate virtual traffic light equipment and corresponding dynamic signal timing information that conforms to the IoV standard based on the traffic light configuration information of the target controlled road section.

[0073] In some optional implementations, the road traffic control device further includes: a trajectory comparison module, used to compare the trajectory of the target vehicle on the target controlled road segment with the traffic control description information to obtain a judgment result indicating whether the target vehicle is driving in accordance with the traffic control description information when it is on the target controlled road segment; and an abnormal driving processing module, used to perform corresponding abnormal driving processing on the target vehicle if the judgment result indicates that the target vehicle is not driving in accordance with the traffic control description information when it is on the target controlled road segment.

[0074] In some optional implementations, the road traffic control device further includes a roadside equipment control module, which sends traffic control configuration information to the road traffic signal controller in the roadside equipment if there is roadside equipment in the target controlled road section that can be used for traffic control.
