Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 shows a block diagram of a lane management system according to an embodiment of the present application. As shown in fig. 1, the lane management system of the present embodiment may include a Road end (Road end) and a Vehicle end (Vehicle end). The Road end may include Road Side equipment (RSU) and lane management equipment. In one example, as shown in fig. 1, the lane management device may be a Mobile Edge Computing (MEC) device. The vehicle end may include one or more vehicles. The roadside device can communicate with the vehicle within the communication range of the roadside device. The vehicle end and the road end can use a wireless communication mode to exchange data, and the road side equipment and the MEC can exchange data in an optical fiber mode and the like. In this embodiment, the target vehicle may be an autonomous vehicle or a non-autonomous vehicle operated by a driver.
In one example, the vehicle may include an On Board Unit (OBU) for broadcasting vehicle attribute information (vehicle information) including a vehicle number, a license plate number, a vehicle category, positioning information, and the like in real time through the wireless communication module, and receiving roadside device information of a roadside.
In one example, the vehicle end of the system may further include: the positioning module is used for providing real-time positioning information of the vehicle, wherein the real-time positioning information comprises position information, course angle, running speed and other information; the map matching device is used for judging whether the vehicle is in a state of needing to receive a lane control instruction according to the real-time positioning information of the vehicle; and the communication module is used for realizing the communication between the road end part and the vehicle end part.
In one example, the route end of the system may further include: the communication module is used for realizing the communication between the road end part and the vehicle end part and the communication between the road end part internal modules; the data processing module is used for analyzing the lane data and generating a control command; the map module is used for providing road high-precision map data of a range governed by the road side equipment; and the map matching module is used for judging whether the vehicle is in the vehicle management area or has the trend of entering the vehicle management area according to the vehicle coordinate position and the course angle.
fig. 2 shows an application scenario diagram of the lane management system according to the embodiment of the present application. In one example, the MEC may communicate with RSU0, RSU1, RSU2, and RSU3, and RSU0, RSU1, RSU2, and RSU3 may each communicate with an OBU of a respective communication range. That is, the roadside apparatus may continuously receive information of all vehicles within its signal coverage range, thereby detecting whether a vehicle has entered the control range of the roadside apparatus, i.e., determining whether the vehicle has arrived for the roadside apparatus. In this embodiment, the roadside apparatus may include a first roadside apparatus, such as RSU1, RSU2, and RSU3, and may further include a second roadside apparatus, such as RSU 0.
in one example, the roadside devices RSU1, RSU2, and RSU3 continuously receive vehicle information within a collection area (roadside devices RSU1, RSU2, and RSU3 communication range), and transmit the collected vehicle information to the MEC. The MEC obtains whether the lane (target lane) in the acquisition area needs to be controlled or not through calculation. If lane control is required, the target lane is determined as a controlled lane, and a control command (also called a control command) for the controlled lane is transmitted to the RSU0 in a command area (communication range of the roadside apparatus RSU 0). The RSU0, upon receiving the regulation command, broadcasts the regulation command to vehicles entering the instruction area. The vehicle entering the instruction area may issue a warning to the driver or a warning to the vehicle main control unit after receiving the control command from the RSU0 so that the main control unit controls the vehicle to avoid.
in one example, the roadside device may communicate with vehicles within its communication range to obtain vehicle information for those vehicles. In one embodiment, the vehicle information includes, but is not limited to, the location, speed, heading angle, vehicle number, vehicle type, license plate number of the vehicle.
An embodiment of the present application provides a lane management method, which may be applied to a first road side device. As shown in fig. 3, the lane management method includes:
And step S31, vehicle information of the vehicle in the communication range is received.
step S32 is a step of determining whether or not a vehicle enters the target lane based on the vehicle information.
If the determination result is yes, step S33 is to transmit the vehicle information of the vehicle entering the target lane to the lane management device.
the target lane is located in the communication range of the first road side device. The target lane may be a dedicated lane or a regulated lane (as shown in fig. 2), for example, when restricted access to the target lane is required, the target lane may be a dedicated lane or a regulated lane. The lane management apparatus may be the MEC described above. The exclusive lane may be a special purpose lane such as a bus lane, an emergency lane, or the like. The regulated lane may be a lane temporarily regulated at a specific time period and a specific road section.
In one embodiment, as shown in fig. 4, step S32 may include:
continuously receiving vehicle information sent by vehicles on a lane;
After receiving the vehicle information, sending the vehicle information to a map matching module;
and judging whether the vehicle enters the information collection area, and if so, sending the vehicle information to the MEC.
In one example, the RSUs of the vehicle information collection area each receive vehicle information within a respective signal coverage area, including vehicle number, license plate number, vehicle type, coordinate location, heading angle, speed, etc. In one example, this step may be implemented by RSU1, RSU2, and RSU3 in fig. 1, where it can be seen from fig. 1 that RSU1, RSU2, and RSU3 continuously receive vehicle information transmitted by vehicles in the lane.
In one example, the map matching module determines whether the vehicle is within the RSU information collection area and the travel track is traveling toward the front of the area based on the coordinate position and the heading angle of the vehicle. In one example, this step may be implemented by the map matching module in FIG. 2.
In one example, the information forwarded to the MEC includes all vehicle information received by RSU1, RSU2, and RSU 3. In one example, this step may be implemented by the communication module in fig. 2.
as shown in fig. 5, the execution method of the map matching module may include:
Continuously receiving map messages;
When the map message comes, starting to receive the vehicle information;
When the vehicle information arrives, judging whether the vehicle is in a map area;
And when the vehicle running course angle is consistent with the road end passing direction, the map matching is successful.
in one example, the vehicle position may refer to vehicle coordinates in the vehicle information. The heading angle may refer to an angle between a vehicle traveling direction and an earth preparation direction, the heading angle being included in the vehicle information.
In one example, the above method steps may be implemented by the geographic matching module shown in FIG. 1.
an embodiment of the present application provides a lane management method, which may be applied to a second roadside device. As shown in fig. 6, the lane management method includes:
and step S61, vehicle information of the vehicle in the communication range is received.
And step S62, when the control command sent by the moving edge computing device is received, the control command is sent to the vehicles in the communication range.
Fig. 7 shows a flowchart of an example of the second roadside apparatus receiving and transmitting the policing command. As shown in fig. 7, in this example, the second roadside apparatus performs the task of receiving and transmitting the policing command by the following flow:
Continuously waiting for receiving the instruction;
When the command comes, the command is sent to the vehicles within the signal coverage range.
In one example, the MEC issues a regulatory command for the target lane to the RSU 0.
In one example, the RSU0 broadcasts a regulatory command for the target lane to the OBU via the wireless communication module. This broadcast communication process may be implemented by a communication module as in fig. 1.
An embodiment of the present application provides a lane management method, which may be applied to a lane management device (e.g., MEC). As shown in fig. 8, the lane management method includes:
step S81, generating a control command for a target lane according to vehicle information sent by first road side equipment corresponding to the target lane;
And step S82, determining a second road side device in the target area connected with the front end of the target lane.
And step S83, sending a control command to the second road side equipment so that the second road side equipment sends the control command to the vehicles in the communication range of the second road side equipment.
In one example, the target lane may be a regulated lane, set by the lane management system according to the instructions of the traffic authority. Whether to generate the control command for the target lane may also be determined based on the vehicle information transmitted by the first road-side device. The front end of the target lane is understood to be the region which is about to enter the target lane and is connected to the target lane, depending on the direction of travel of the vehicle. For example, an intersection that is about to enter the target lane, an entrance of the target lane, or the like. The MEC can receive vehicle information of each vehicle within a communication range of the first road side equipment and generate a control command for the target lane according to the vehicle information.
that is, the MEC may determine whether to generate a regulation command for the target lane according to the vehicle information of the vehicle within the first roadside device communication range, and transmit the regulation command to the second roadside device located in the target area at the front end of the target lane, so that the second roadside device transmits the regulation command to the vehicle within the second roadside device communication range.
in one example, the MEC sends a policing command to the second roadside device after determining the second roadside device. After receiving the regulation command, the second roadside device can transmit the regulation command to all vehicles within the coverage range of the signal in a broadcast mode.
in one embodiment, the first roadside apparatus may act as the second roadside apparatus. For example: when major activities occur, road control is often required to be actively and temporarily carried out, and at the moment, control commands can be sent through all roadside devices in the MEC communication range, so that control commands can be sent to all vehicles in the lane management system, and large-range road control is achieved. Therefore, the road can be flexibly regulated at the specified time and the specified road section.
That is, all roadside apparatuses may respectively perform the lane management method described above. That is, the first roadside apparatus and the second roadside apparatus may be interchanged according to different application scenarios or application times.
in one example, the vehicle end may send its own vehicle information to the road end, and may also receive a control command, so as to avoid or bypass a target lane corresponding to the control command. As shown in fig. 9, the method may include:
And sending the vehicle information of the vehicle, namely sending the vehicle information of the vehicle to the outside.
And judging whether a control command is received.
The map matching module judges whether the vehicle is in the RSU instruction area or not according to the coordinate position and the course angle of the vehicle, and the driving track is driving towards the front of the area.
It is determined whether the vehicle is traveling in the command area. And if the vehicle is judged to be running in the instruction area, prompting the vehicle to avoid a target lane corresponding to the control command through the OBU.
in one example, the own vehicle information may include vehicle number, coordinate position, traveling direction, current speed, and the like.
In one example, the regulatory command may be sent by the RSU corresponding to the intersection before entering the target lane (e.g., RSU0 in fig. 1).
In one embodiment, the determining whether to generate the regulation command for the target lane according to the vehicle information of the vehicle in the first roadside device communication range may include any one of the following manners: calculating the vehicle density in the target lane according to the vehicle information, and generating a control command when the vehicle density exceeds a first preset value; and calculating the average speed of the vehicles in the target lane according to the information of the vehicles, and generating a control command when the average speed exceeds a second preset value.
Specifically, the order of determining the vehicle density and the vehicle average speed may be adjusted according to actual conditions, that is, the vehicle density may be compared first and then the vehicle average speed may be compared, or the vehicle average speed may be compared first and then the vehicle density may be compared. Moreover, the vehicle density and the average speed of the vehicle can be simultaneously compared, and the vehicle density and the average speed of the vehicle can be comprehensively evaluated in a priority weighting mode, so that whether the control command needs to be generated or not can be determined.
In one example, as shown in fig. 10, when the judgment vehicle information has come, the repeatedly collected vehicle information is deduplicated. Because the coverage range of each roadside device may overlap, the vehicles are still in a running state in the road, and therefore the roadside devices are likely to acquire multiple sets of vehicle information of the same vehicle. In the process of filtering the vehicle information, the MEC can filter the vehicle information with the same number at the same time according to the vehicle number in the vehicle information.
After the vehicle information filtering step, the vehicle density in the designated area can be counted. The vehicle density may be the number of filtered vehicles received by the MEC. The calculation of the vehicle density can be updated typically 10 seconds. And comparing the vehicle density with a preset density threshold value to judge whether the lane control is required to be carried out on the target lane.
Meanwhile, whether lane control is required or not can be judged by calculating the average speed of the vehicle and comparing the average speed of the vehicle with a preset average speed threshold, wherein the average speed of the vehicle can be the average value of all filtered vehicles received by the MEC. The calculation of the average speed can be updated typically once in 10 seconds.
It should be noted that, in actual operation, whether to perform lane control may be determined by one of the vehicle density and the average speed, or may be determined by integrating the vehicle density and the average speed.
In one embodiment, as shown in fig. 11, the lane management method further includes:
And step S111, receiving vehicle information of vehicles in the communication range of each first road side device, wherein the vehicle information comprises vehicle types.
And S112, determining the violation vehicles from the vehicles according to the vehicle types corresponding to the vehicles and the preset passing vehicle types.
And S113, recording violation information of the violation vehicle, wherein the violation information comprises the license plate number of the violation vehicle.
In one example, as shown in fig. 12, the MEC continuously receives vehicle information sent by a plurality of first roadside devices, thereby determining whether a vehicle enters a monitoring area. The MEC can filter repeated vehicle information according to the unique vehicle number, calculate the vehicle density and the traffic flow speed in the whole vehicle information collection area (target lane), compare the obtained result with a preset threshold value, and issue a control command if the result exceeds the threshold value. When a control command is issued, if a vehicle enters a target lane, the MEC screens out the illegal vehicles entering the target lane through a preset vehicle type, and extracts vehicle numbers from the vehicle information of the illegal vehicles.
Fig. 13 is a flowchart showing an application example of the lane management method of the present application. As shown in fig. 13, the entire lane management process is as follows: OBU broadcast vehicle information, RSU receives this vehicle information broadcast after, judges whether in the collection region through map matching: if the vehicle is not in the acquisition area, continuously receiving the vehicle information; if in the acquisition area, the vehicle data is uploaded to the MEC. And after receiving the vehicle information, the MEC performs data processing to judge whether the vehicle needs to generate a control command: if the control command does not need to be generated, continuously receiving the vehicle information; if a policing command needs to be generated, a policing command is generated. After the control command is generated, the control command is sent to the RSU, the RSU transmits the command to the OBU, and the OBU judges whether the vehicle is in a command area or not through map matching after receiving the command: if the vehicle is not in the instruction area, directly ending; if the vehicle is in the command zone, an avoidance warning is issued to the vehicle.
in some application scenes, the traffic control of a special lane (such as a bus lane) is generally carried out by time-interval and region-by-region, and the current general method of traffic control departments is to draw a mark on a road or directly and manually set a roadblock, so that on one hand, the special lane cannot be flexibly configured, on the other hand, no matter whether the mark is drawn or the roadblock is set, manual materials are consumed, meanwhile, pollution can be caused, and the process of drawing the mark and setting the roadblock occupies the lane, thereby influencing the use efficiency of the lane. The solution of the application can realize flexible configuration of the special lane in the designated time period and the designated area, and improve the use efficiency of the lane.
