Optionally, referring to fig. 2, fig. 2 is a partial structural schematic diagram of an alternative traffic grooming system according to the present application. The traffic grooming system 20 further includes a crossing object 203, and the acquisition device 201 is disposed on the crossing object 203, so that the acquisition device 201 has a preset distance from the ground, and thus scene information in a certain range can be acquired.
Alternatively, the intersection object may be a utility pole, a signal light pole, a pole that limits the height of the vehicle, and the like.
Optionally, the acquisition device and the processor may directly communicate via a network; the processor and the vehicle may communicate over a network.
Optionally, the processor may be a server, a desktop computer, a notebook computer, or other processing devices capable of performing data processing.
The following describes a specific embodiment of a traffic grooming method of the present application, and fig. 3 is a schematic flow chart of a first alternative traffic grooming method of the present application, and the present specification provides the method operation steps as in the embodiment or the flow chart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In practice, the system or server product may be implemented in a sequential or parallel manner (e.g., parallel processor or multi-threaded environment) according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 3, the method may include:
s301: and acquiring scene information of a first preset range of the intersection by using acquisition equipment.
In an alternative embodiment, the first preset range and the second preset range may include a range with the acquisition device as an origin and a preset distance as a radius, or a range extending in a certain specific direction with a preset shape, where the specific direction may be one or more of the front, the back, or the side of the acquisition device, and the preset shape may be a fan shape or a shape similar to a fan shape.
In one possible embodiment, the collecting device is arranged on the signal lamp; the acquisition equipment is convenient to acquire the scene information of the first preset range of the intersection where the signal lamp is located.
Optionally, the acquisition device may be a camera, a laser radar, a millimeter wave radar, or the like, which is capable of acquiring and identifying object information within a preset range. The number of the collecting devices can be one or more according to the requirement. Generally, the range of the laser radar is smaller than that of a millimeter wave radar, the millimeter wave radar can detect the length of a vehicle queued in a lane, and the camera can accurately identify image information, such as information of the vehicle, people, license plate numbers, construction areas and the like, so that the type of an event which is easy to cause traffic jam, namely a scene condition described below, can be conveniently and accurately judged subsequently.
Optionally, a detection principle based on a laser radar is known, and the detection is realized based on the emission of laser by a target object, so that when a first vehicle in a lane is a higher and wider vehicle, such as a truck, a van and the like, the laser radar cannot detect a trolley behind the vehicle, and a detection blind area is further caused; in order to avoid the situation, in the embodiment of the application, the acquisition equipment comprises a plurality of cameras, a plurality of laser radars and a plurality of millimeter wave radars, and the accuracy of the scene information can be effectively ensured through the supplement of the millimeter wave radars and the cameras.
In order to improve the data processing efficiency and ensure that a driver can know traffic information in time; optionally, the processor is located on the intersection object, so that the real-time performance of information processing can be improved, for example, for a ghost probe scene, a pedestrian appears in front of a bus, but a car behind the bus cannot see the pedestrian, and of course, the processor can also be a remote device according to needs.
Optionally, the scene information includes a picture, a video and point cloud data of a target object (a vehicle, a person or an object) within a preset range.
In this embodiment, a plurality of scene conditions can be determined based on the scene information, and the influence degrees of different scene conditions on traffic congestion are slightly different, so as to better dredge traffic or avoid traffic congestion, the scene conditions are divided into three types, the first type is that traffic congestion exists; the second is that there is construction on the lane; the third is that there is or may be a risk accident.
The three scene conditions will be described below.
For the first category of scenario conditions, the following is set forth.
S302: and if the traffic jam condition in the first preset range is determined according to the scene information, determining jammed lane information.
In an alternative embodiment where it is determined that a traffic congestion condition exists within the first predetermined range based on the context information, the processor may acquire a video of a first preset range by using the camera, acquire point cloud data of the first preset range by using the millimeter wave radar and the laser radar, thereby determining the number of vehicles in the target lane or intersection, the distance between the vehicles and the running speed of the vehicles, if the running speed is less than or equal to the preset speed, one or more conditions that the number of vehicles is greater than the preset number or the distance between the vehicles in the preset number is less than or equal to the preset distance are satisfied, the traffic jam condition in the first preset direction can be confirmed, and the number of the congested lanes can be confirmed based on the judgment condition, and of course, the judgment condition is not limited as required.
Optionally, in some scenarios, it is not very accurate to perform identification only according to the queuing length, for example, the first vehicle is a large vehicle, but a plurality of vehicles are immediately followed by the first vehicle, but only one large vehicle can be detected in actual detection, and thus it is not very accurate to determine the queuing length.
In one possible embodiment, the lane information includes the location of the lanes and the number of lanes. The position of the lane may include the position of the lane in the current lane direction, and if there are 3 lanes in the lane direction, the position of the lane includes left, middle, and right sides, for example.
S303: generating a first regulation and control instruction based on the congested lane information, wherein the first regulation and control instruction is used for indicating vehicles in a second preset range of the intersection to travel towards a target direction; the target lane indicated by the target direction and the lane in which the vehicle is running are positioned in different directions of the intersection, and the target lane is an uncongested lane; the second predetermined range is greater than or equal to the first predetermined range.
Optionally, the first control instruction may be a voice message broadcasted to the vehicle, or may be a lane driving road sign indication picture displayed on a crossing display screen or a vehicle display screen, and as described in the above example, when a lane in front of a crossing is occupied or a congestion exists, at this time, a road sign indication of a straight lane in a straight lane behind the crossing may be changed to a left turn or a right turn on the display screen, so as to prevent the vehicle in the current lane from directly driving into a congested lane through the crossing, and further increase the congestion of the traffic, it should be noted that the two lanes before and after the crossing on one straight line are used as an example, and actually crossed lanes are a first lane and a second lane, respectively, when the first lane is a congestion lane, and the vehicle in the second lane needs to drive to the first lane by a left turn or a right turn, the left turn or right turn road sign corresponding to the second lane may be changed to be directly, to alleviate traffic congestion.
In order to further alleviate the traffic jam, in a possible embodiment, after step S303, the method further includes: generating a second regulation and control instruction based on the congested lane information, wherein the second regulation and control instruction is used for instructing signal lamp control equipment to adjust the time length of a signal lamp of a target intersection, which is displayed as a first color, to a first target time length, and the time length of the signal lamp of the target intersection, which is displayed as a second color, to a second target time length; the first target time length is longer than the original time length of the signal lamp displayed as the first color; the second target time length is less than the original time length of the signal lamp displayed as a second color; the first color indicates that the vehicle is to stop waiting; the second color is indicative of vehicle passability; the target intersection is the first N intersections of the intersection, and N is an integer greater than or equal to 1.
Alternatively, the first color may be set to a color with strong warning property such as red, yellow, etc., and the second color may be set to green.
The traffic jam condition is relieved, and meanwhile the running order of vehicles is guaranteed. Optionally, intersections before the intersection may be sorted according to distances from the intersection, and a first target time length of the first color and a second target time length of the second color of each intersection are respectively set, where the longer the distance from the intersection to the target intersection is, the longer the time of the first target time length is, and the shorter the second target time length is, for example, when N is 2, the first target time length of the first 2 intersections may be 60 seconds, the second target time length may be 20 seconds, the first target time length of the first 1 intersection may be 50 seconds, and the second target time length may be 25 seconds. Therefore, the traffic speed is gradually slowed down, and serious congestion conditions and event traffic are avoided.
It should be noted that, for information with low processing efficiency requirement, data processing may be performed based on the cloud, and for information with high processing efficiency and timeliness requirement, processing may be performed based on a processor located at the intersection.
For the second category of scenario conditions, the following is set forth. Referring to fig. 4, fig. 4 is a schematic flow chart of a second alternative traffic grooming method according to the present application. After step S301, the method further includes:
s401: and if the fact that construction exists in the first preset range is determined according to the scene information, obtaining lane information occupied by the construction.
To improve the efficiency of data acquisition. In a possible embodiment, the lane information occupied by the construction in step S401 may be specifically described as: acquiring the information of the lane occupied by the construction by using the acquisition equipment or the communication equipment; the communication equipment is used for sending the lane information occupied by the construction to the acquisition equipment; the communication equipment is arranged on an enclosure which is positioned at the edge of the area occupied by the construction.
In an embodiment of acquiring the information of the lane occupied by construction by using the acquisition equipment, a video can be acquired by using a camera, and the construction scene and the construction area are determined by using a recognition algorithm, so that the information of the lane occupied by construction is determined.
S402: generating a second regulation and control instruction based on the lane information occupied by the construction, wherein the second regulation and control instruction is used for instructing signal lamp control equipment to regulate the time length of a signal lamp of a target intersection, which is displayed as a first color, to a first target time length, and the time length of the signal lamp of the target intersection, which is displayed as a second color, to a second target time length; the first target time length is longer than the original time length of the signal lamp displayed as the first color; the second target time length is less than the original time length of the signal lamp displayed as a second color; the first color indicates that the vehicle is to stop waiting; the second color is indicative of vehicle passability; the target intersection is the first N intersections of the intersection, and N is an integer greater than or equal to 1.
In order to further improve the traffic evacuation efficiency and avoid that the vehicle is always in the parking waiting state when the number of lanes occupied by the construction is all occupied, optionally, after step S402, the method may further include: and generating a first regulation and control instruction based on the lane information occupied by the construction.
For the third category of scenario conditions, the following is set forth. Referring to fig. 5, fig. 5 is a schematic flow chart of a third alternative traffic grooming method according to the present application. After step S301, the method further includes:
s501: and if the traffic accident exists in the first preset range according to the scene information, determining the risk level of the traffic accident.
Optionally, the risk level may be determined based on preset time for handling the traffic accident, the number of occupied lanes, and subsequent secondary accident influence factors that may occur, or one of the conditions is met, that is, the condition is determined to be the corresponding risk level, and the higher the risk level is, the more severe the influence caused by the traffic accident is, the longer the handling time is.
In this embodiment, the traffic accident may be a collision accident, or a chemical gas leakage or explosion accident. Of course, the present invention may also include a hidden traffic accident, for example, a high temperature weather, a vehicle with flammable and explosive articles is driven on a lane, if the leakage and the information that an explosion may occur are not detected, the risk level of the accident may be defined as a lower level, and then only a warning information sending vehicle needs to be generated to prompt the driver.
Optionally, the mode of determining whether the leakage exists may be to arrange a gas detector near the lane, and the collision accident or the explosion accident may be determined based on the above-mentioned acquisition devices such as the camera.
S502: if the risk level is less than the preset level, warning information is generated and sent to the vehicle; otherwise, generating accident information and sending the accident information to an emergency management organization.
It should be noted that no matter the risk level of the accident, the generated warning information and the accident information need to be reported to the traffic management platform, and if the risk level is greater than the preset level, the warning information and the accident information can be pushed to relevant organizations such as medical rescue, fire fighting and the like according to the field identification condition. Based on the needs, the first regulation and control instruction and the second regulation and control instruction can be generated so as to avoid secondary accidents and traffic jam; the method and the system can realize notification and alarm of other traffic participants through various modes based on cooperation and control of vehicles, roads and clouds; on the basis of providing the traffic dispersion efficiency, the manpower is also saved.
