Description

Technical Field

[0001] This application relates to the field of intelligent transportation technology, and in particular to a vehicle traffic control method, system and electronic device. Background Technology

[0002] Roads have various lanes. Lanes allowing traffic in only one direction are called one-way lanes, such as left-turn lanes, straight-ahead lanes, and right-turn lanes. Lanes allowing traffic in multiple directions are called mixed lanes, such as U-turn + left-turn lanes, left-turn + straight-ahead lanes, and straight-ahead + right-turn lanes. At intersections with both one-way and mixed lanes, especially intersections with both one-way and right-turn lanes, right-turning vehicles are significantly affected by straight-ahead vehicles when there are no traffic control measures. While straight-ahead vehicles are waiting for the green light, right-turning vehicles can only queue up. Furthermore, right-turning vehicles weave through the straight-ahead traffic, needing to turn right during the straight-ahead green light. At this time, non-motorized vehicles and pedestrians on the right are also crossing, slowing their speed and causing congestion, reducing traffic efficiency. Furthermore, the simultaneous crossing with straight-ahead non-motorized vehicles and pedestrians on the right also poses a safety hazard.

[0003] In summary, existing technologies cannot effectively manage the mixed lanes on the right side of intersections, affecting vehicle traffic and reducing the efficiency of vehicle traffic in the mixed lanes. This, in turn, increases the risk of traffic accidents involving right-turning vehicles and non-motorized vehicles and pedestrians going straight. Summary of the Invention

[0004] This application provides a vehicle traffic control method, system, and electronic device to improve the traffic efficiency of right-turning vehicles in a mixed lane that combines straight-ahead and right-turn traffic.

[0005] This application provides a vehicle traffic control method, including:

[0006] Obtain key information of a road intersection scene, wherein the key information of the road intersection scene includes: the driving direction information of the lanes in the road intersection scene, and the information of the traffic lights used to control the passage of vehicles in the lanes;

[0007] Based on the aforementioned key information, determine whether the following preset conditions are met:

[0008] The driving direction information of the lanes in the road intersection scenario includes: the driving direction of the first lane and the driving direction of the second lane; wherein, the first lane supports at least one driving direction, the second lane supports at least two driving directions, and both the first lane and the second lane support going straight; the driving direction supported by the second lane also includes turning right;

[0009] The traffic light is green.

[0010] When the preset conditions are met, before the traffic light changes from the current green light to the red light or the yellow light, control information is output to enable straight-going vehicles in the second lane to change lanes into the first lane.

[0011] The above method enables lane guidance for straight-going vehicles entering the mixed straight-going and right-turn lanes. When the straight-going light is red, straight-going vehicles are prohibited from stopping in the mixed lane waiting area to wait for the green light, thus solving the problem of right-turning vehicles queuing and improving the traffic efficiency of right-turning vehicles in the mixed straight-going and right-turn lanes.

[0012] In some embodiments, the key information of the road intersection scene also includes: information on the virtual waiting line preset on the second lane, wherein the virtual waiting line is a virtual waiting line generated in advance on the first lane and the second lane in the road intersection scene image captured by the image acquisition device based on the virtual and real boundary line information between the first lane and the second lane;

[0013] The preset conditions also include:

[0014] The vehicles traveling straight in the second lane did not pass the virtual waiting line.

[0016] In some embodiments, the key information of the road intersection scenario also includes: lane stop line information;

[0017] The control information is output at a first moment before the traffic light changes from the current green light to the red light or the yellow light. The first moment is spaced from the moment the traffic light changes from the current green light to the red light or the yellow light by a first duration. The first duration is determined based on the length of the solid line between the first lane and the second lane, and the average speed of vehicles passing through the second lane. The length of the solid line is the length of the solid line between the virtual waiting line and the stop line of the lane.

[0018] In some embodiments, the method further includes:

[0019] When the traffic light is red, before the traffic light changes from red to green, control information is output to allow straight-going vehicles in the first lane and / or the second lane to pass through the first lane.

[0020] In some embodiments, the control information is output and displayed through a preset display screen.

[0021] In some embodiments, the key information further includes: information on the virtual waiting line preset on the second lane, information on the stop line of the lane, and vehicle passage instruction information currently displayed on the preset display screen;

[0022] The method further includes:

[0023] When the display screen currently shows a vehicle passage instruction message that straight-going vehicles should enter the first lane to wait, and there is a target vehicle passing through the virtual parking line in the second lane, the first image of the target vehicle is captured.

[0024] When the target vehicle crosses the stop line, a second image of the target vehicle is captured;

[0025] When the target vehicle passes through the preset virtual right-turn line at the intersection, the first and second images of the target vehicle are deleted; when the target vehicle passes through the preset virtual straight line or virtual left-turn line at the intersection, the third image of the target vehicle is captured, and the capture information of the target vehicle is reported. The capture information includes the first, second, and third images of the target vehicle.

[0026] Another vehicle traffic control method provided in this application embodiment is applied to an information notification device, and the method includes:

[0027] Before the traffic light changes from green to red or yellow, control information is output; the control information is used to instruct vehicles going straight in the second lane to change lanes into the first lane.

[0028] The first lane supports at least one direction of travel, the second lane supports at least two directions of travel, and both the first lane and the second lane support going straight; the second lane also supports right turns.

[0029] In some embodiments, the straight-going vehicle does not pass through a preset virtual waiting line on the second lane. The virtual waiting line is a virtual waiting line generated in advance on the first lane and the second lane in the road intersection scene image captured by the image acquisition device based on the virtual and real boundary line information between the first lane and the second lane.

[0030] This application provides a vehicle communication control system, comprising: an image acquisition device, a server, and an information notification device; wherein,

[0034] Based on the aforementioned key information, determine whether the following preset conditions are met:

[0035] The driving direction information of the lanes in the road intersection scenario includes: the driving direction of the first lane and the driving direction of the second lane; wherein, the first lane supports at least one driving direction, the second lane supports at least two driving directions, and both the first lane and the second lane support going straight; the driving direction supported by the second lane also includes turning right;

[0036] The traffic light is green.

[0037] When the preset conditions are met, before the traffic light changes from the current green light to the red light or yellow light, control information for causing straight-going vehicles in the second lane to change lanes into the first lane is output to the information notification device.

[0038] The information notification device is used to receive the control information and output the control information before the traffic light changes from the current green light to the red light or the yellow light.

[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0071] This application provides a vehicle traffic control method, system, and electronic device to improve the traffic efficiency of right-turning vehicles in a mixed lane that combines straight-ahead and right-turn traffic.

[0072] The methods, systems, and electronic devices are based on the same concept in the application. Since the methods and devices solve problems in similar ways, the implementation of the devices and methods can refer to each other, and the repeated parts will not be described again.

[0073] The terms "first," "second," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein.

[0074] The following examples and embodiments are to be understood as illustrative only. While this specification may refer to "a," "an," or "some" examples or embodiments in several places, this does not mean that every such reference relates to the same example or embodiment, nor does it mean that the feature applies only to a single example or embodiment.

Furthermore, terms such as "comprising" and "including" should be understood not to limit the described embodiments to consisting only of those features mentioned; such examples and embodiments may also include features, structures, units, modules, etc., not specifically mentioned.

[0075] The various embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that the order in which the embodiments are presented in this application represents only a chronological order and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0076] The technical solution provided in this application only uses intersection scene information and does not require vehicle system expansion support to control straight-going vehicles entering the "straight + right-turn mixed lane". Specifically, when the straight-going light is red, it prohibits straight-going vehicles from stopping in the mixed lane waiting area to wait for the green light, thus preventing right-turning vehicles from queuing. Furthermore, this application also provides a method for capturing images of straight-going vehicles that do not enter the mixed lane waiting area as required, to warn and penalize violating vehicles.

[0077] This application requires the use of intersection scene information, so the applicable scenarios and required scene information will be explained before the specific system introduction.

[0078] This application embodiment applies to intersections with at least two lanes, including a first lane and a second lane. The first lane supports at least one direction of travel, and the second lane supports at least two directions of travel. Both the first and second lanes support straight-ahead traffic. Specifically, for example, the first lane can be a one-way lane or a mixed lane; the second lane is a "straight-ahead + right-turn mixed lane," and both the first and second lanes support straight-ahead traffic. For example, an intersection has two lanes, one is a "left-turn + straight-ahead mixed lane," and the other is a "straight-ahead + right-turn mixed lane," both of which support straight-ahead traffic. Figure 1 This is a road intersection scenario that includes a "straight one-way lane" and a "straight + right turn mixed lane". All lanes support straight-through vehicles, while only the rightmost lane supports right-turning vehicles. If there are straight-through vehicles waiting for the green light, right-turning vehicles need to follow the queue.

[0079] The embodiments of this application are as follows: Figure 2 The example shown illustrates a two-lane road intersection with a "straight one-way lane" and a "straight + right turn mixed lane" (actual scenarios are not limited to this one; please refer to the above description of applicable scenarios).

[0080] against Figure 2 The key information of the road intersection scenario shown in the embodiments of this application is as follows: Figure 3 As shown, it includes:

[0081] Traffic light information, namely, the change information of traffic lights at intersections (such as the change order of each color of the traffic light, the time when the currently lit traffic light is lit, the duration of the light, the interval between two consecutively lit traffic lights of different colors, etc.).

[0082] Lane travel direction information, that is, the specific travel direction information of each lane corresponding to the intersection;

[0083] Lane stop line information, that is, the stop line information of each lane at the intersection (specifically including the position information of the stop line);

[0084] Lane boundary information, such as information on dashed and solid lines between adjacent lanes (specifically, including the position information of dashed lines between adjacent lanes and the position information of solid lines between adjacent lanes).

[0085] According to traffic rules: if the lane divider is dashed, it is permissible to move from one lane to the other (i.e., lane changing is allowed); if the lane divider is solid, it is not permitted to move from one lane to the other (i.e., lane changing is not allowed). Based on the information about dashed and solid lane dividers, a "virtual waiting line" (e.g., a line where the lane divider changes from dashed to solid) can be generated near the point where the lane divider changes from dashed to solid (e.g., the intersection of a dashed and solid line). Figure 4 (as shown); and an electronic screen for displaying the "straight-through vehicle passage instruction" signal is pre-set near the "virtual waiting line" (refer to the waiting signal electronic screen set at the intersection with the waiting area). For example, the electronic screen is set in front of the "virtual waiting line" (that is, on the side close to the road intersection, which is the direction of vehicle movement. The specific location can be determined according to actual needs. This application embodiment does not impose any restrictions).

[0086] As can be seen, the "virtual waiting line" and the electronic screen used to display the "straight-through vehicle passage instruction" signal are extended information for key information in conventional road intersection scenarios in this application embodiment.

[0087] For ease of explanation in the following description, the "straight-ahead one-way lane" will be referred to as lane one, the "straight-ahead + right-turn mixed lane" as lane two, the "virtual waiting line" as the waiting line, and the electronic screen used to display the "straight-ahead vehicle passage instruction" signal as the display screen. The final scenario diagram is as follows: Figure 4 As shown.

[0088] Should Figure 4 In the scenario shown, both the first and second lanes allow straight-through vehicles to pass, but these vehicles must proceed according to traffic signals. The second lane also allows right-turning vehicles to pass, unrestricted by traffic signals; that is, as long as no straight-through vehicles are stopped in the second lane waiting for the green light, right-turning vehicles can proceed. Based on this, this application provides a method to instruct straight-through vehicles to stop in the first lane and wait for the green light, thus ensuring the smooth flow of traffic in the second lane and preventing right-turning vehicles from queuing due to straight-through vehicles stopping in the second lane, which would reduce the traffic efficiency of the second lane. Specific vehicle traffic control methods include, for example:

[0089] Step 1, see Figure 5 According to the traffic light rules, at time T1 before the traffic light changes from green to red (or yellow), the control display screen updates the vehicle passage instruction information to "Straight-going vehicles please enter the first lane to wait," instructing straight-going vehicles in the second lane that have not yet crossed the waiting line to change lanes and enter the first lane to stop and wait. This ensures that there are no vehicles waiting in the second lane, and also prevents right-turning vehicles from queuing. Therefore, right-turning vehicles can pass directly in the second lane, improving the right-turning capacity of the second lane. Here, T1 is the first moment before the light changes (from the current green light to red or yellow light), and the interval between the first moment and the light change is a first duration. The specific value of the first duration can be determined according to actual needs, and this application embodiment does not impose any restrictions, as long as it ensures that vehicles traveling in the second lane can change lanes to the first lane. For example, if a vehicle traveling in the second lane has not yet reached the area corresponding to the solid line between the first and second lanes, it can cross the dashed line between the first and second lanes to enter the first lane.

[0090] If the display screen only updates its information when the traffic light changes from green to red (or yellow), vehicles that have already crossed the second lane's waiting line may not have enough time to cross the stop line and will have to stop in the second lane, causing right-turning vehicles to queue and affecting the effectiveness of the solution. Therefore, in some embodiments, the time it takes for a vehicle to cross from the waiting line to the stop line can be estimated based on the length of the solid lines in the two lanes at the intersection and the average speed of vehicles; this is the first duration. Different durations can also be set and optimized at the intersection. For example, if the first duration is 3 seconds, the display screen updates its information 3 seconds before the traffic light changes from green to red (or yellow). If many vehicles cross the waiting line before the information changes but do not have enough time to cross the stop line before the red light turns on, the value of the first duration can be increased in real time, such as to 4 seconds, 5 seconds, or even longer, to ensure that as few vehicles as possible do not have enough time to cross the stop line before the red light turns on.

[0091] Step 2, see Figure 6 At time T2, before the traffic light turns green, the display screen updates the message "Straight-through vehicles may enter the second lane," allowing straight-through vehicles in the first lane that have not yet crossed the waiting line to change lanes and enter the second lane; or, see [link to other documentation]. Figure 7If there are no vehicles in the second lane, or if there is still remaining capacity (e.g., few right-turning vehicles and no queuing), the updated display message "Straight-going vehicles may enter the second lane" allows vehicles going straight in the first lane (without crossing the virtual waiting line) to safely change lanes into the second lane. At this time, both straight-going and right-turning vehicles in the second lane can proceed, and straight-going vehicles in the second lane do not need to change lanes to the first lane. T2 refers to the second moment before the light changes (from red to green), and the interval between the second moment and the light change is a second duration. The specific value of the second duration can be determined according to actual needs, and this embodiment does not impose any restrictions.

[0092] Vehicles changing lanes from the first lane to the second lane, or vehicles traveling straight in the second lane, require a certain amount of time to travel from the waiting line to the stop line, and are not subject to traffic lights before reaching the stop line. Therefore, in some embodiments, the second duration can be adjusted to ensure that the traffic light changes from red to green, or is about to change from red to green, when the vehicle approaches the stop line after changing lanes, thus minimizing the time that straight-going vehicles spend in the second lane after changing lanes. The second duration can be determined by referring to the value of the first duration (e.g., taking the same value), or it can be determined using the same evaluation and adjustment method as the first duration.

[0093] Considering that some vehicles that fail to follow signs and enter the first lane to wait for traffic going straight may remain stopped in the second lane, obstructing right-turning vehicles, some embodiments provide a method for capturing vehicles that fail to wait as instructed. The captured vehicles can be sent to their owners as a warning or as evidence for penalties. See also... Figure 8 Specific methods for capturing images of vehicles violating traffic rules include, for example:

[0094] Step 1: When the vehicle is traveling in the second lane and its rear end passes the waiting line ( Figure 8 Near point A, if the traffic instruction on the display screen reads "Straight-going vehicles please enter the first lane to wait," it indicates that the vehicle may not be following the instructions, and a pre-capture image (the first image) should be taken. The pre-captured image must include vehicle information (license plate, etc.) and the instruction information on the display screen.

[0095] Step 2: When the vehicle is traveling in the second lane and the front of the vehicle touches the stop line ( Figure 8 Near point B, take another pre-capture image (the second image). If the vehicle did not capture the first image, no image needs to be captured when passing point B.

[0096] Step 3: When the vehicle crosses the stop line and touches the virtual straight line ( Figure 8(Near point C) This indicates that the vehicle proceeded straight through the intersection without following the instructions on the display screen. Capture the third image to complete the image capture. If the first and second images were not captured, no image capture is required when the vehicle passes point C.

[0097] Step 4: When the vehicle crosses the stop line and touches the virtual right-turn line ( Figure 8 (Near point D in the middle) This indicates that the vehicle is turning right through the intersection. The information displayed on the screen is invalid for right-turning vehicles. There is no need to capture the target vehicle. The pre-capture of the first and second images is canceled, and the capture event ends.

[0098] Step 5: Once the three images are captured, it indicates that the vehicle did not follow the instructions on the display screen, constituting a traffic violation. The three captured images are uploaded to the traffic system as evidence of the violation. The traffic system can choose to push the violation information to the vehicle owner as a warning, reminding the owner to follow the instructions when passing through the intersection in the future; or it can use it as the basis for a traffic violation penalty to punish the vehicle owner.

[0099] A more detailed process for capturing and processing images of vehicles violating traffic rules is as follows: Figure 9 As shown, it includes the following steps:

[0100] S901. Determine if there is a vehicle traveling in the second lane. If yes, proceed to step S902; otherwise, end this capture processing procedure.

[0101] S902. Detect the vehicle (hereinafter referred to as the target vehicle) traveling in the second lane to pass the waiting line, that is, detect whether the target vehicle has passed the waiting line in the second lane. When the rear of the target vehicle passes the waiting line, execute step S903.

[0102] S903. Determine the traffic indication status of the signal on the display screen. If the signal on the display screen is "Straight-going vehicles please enter the first lane to wait", then proceed to step S904; otherwise, if the signal on the display screen is "Straight-going vehicles may enter the second lane to pass", then end this capture processing procedure.

[0103] S904. Take the first snapshot of the target vehicle to obtain the first image of the target vehicle.

[0104] The pre-capture described in this application embodiment is actually a capture, but the image captured at this time does not necessarily mean that it will be output as the final result. It may be deleted after subsequent processing steps. Therefore, the capture at this time is called pre-capture.

[0105] S905. Detect the front of the target vehicle touching the stop line. When the target vehicle is driving in the second lane and its front touches the stop line, execute step S906.

[0106] S906. Capture the target vehicle again to obtain a second image of the target vehicle that was previously captured.

[0107] S907. When the target vehicle crosses the stop line, determine whether the target vehicle touches the direction line. The type of direction line includes: virtual straight line, virtual right turn line, and virtual left turn line. If the target vehicle touches the virtual right turn line, proceed to step S910. If the target vehicle touches the virtual straight line or virtual left turn line, proceed to step S908.

[0108] In this embodiment of the application, the direction line refers to a virtual direction line set at a road intersection (e.g., Figure 8 The virtual straight lines and virtual right-turn lines shown are similar to the virtual waiting lines mentioned above; they are not actual road markings.

[0109] S908. Perform a third capture on the target vehicle to obtain the third image of the target vehicle.

[0110] S909. Capture and report information about the target vehicle, for example, upload three captured images of the target vehicle as evidence of a traffic violation to the traffic system.

[0111] S910. Cancel the first and second images pre-captured for the target vehicle, where cancellation is, for example, a deletion operation.

[0112] It should be noted that in the embodiments of this application, the target vehicle can be continuously tracked and captured (for example, by combining with a target tracking algorithm), or the preset scene can be directly captured by a pre-set image acquisition device. Then, the captured images are used to identify the target and determine whether there are multiple images of the same target (vehicle with the same license plate number) in the multiple captured images. For example, if the same vehicle is not captured in the first and second images, then when the vehicle crosses the stop line and touches the virtual straight line, it is not necessary to capture an image.

[0113] In addition, in this embodiment of the application, different captured images can be captured by the same image acquisition device. For example, an image acquisition device that can rotate 360 ​​degrees can be set up at a road intersection, and the angle can be rotated at any time according to the control command to capture images at different positions.

[0114] Different captured images can also be acquired using different image acquisition devices. For example, at the intersection of a road, an image acquisition device can be set up to capture the first and second images directly opposite the second lane. Furthermore, at the intersection of the road, separate image acquisition devices can be set up to capture images of vehicles touching the virtual straight line, virtual right turn line, and virtual left turn line respectively. That is, separate image acquisition devices can be set up to capture images of vehicles touching the virtual straight line, virtual left turn line, and virtual right turn line respectively.

[0115] The specific settings for the camera to acquire images can be determined according to actual needs, and no restrictions are imposed in this application embodiment.

[0116] As can be seen from the above embodiments, the control end can be a backend server, or a frontend terminal such as a camera or traffic light. This application provides a vehicle traffic control method, see [link to relevant documentation]. Figure 10 ,include:

[0117] S101. Obtain key information of the road intersection scene, wherein the key information of the road intersection scene includes: the driving direction information of the lanes in the road intersection scene, and the information of the traffic lights used to control the passage of vehicles in the lanes.

[0118] The key information of the road intersection scene is obtained, for example, by monitoring the road intersection scene, specifically by obtaining key information of the road intersection scene through surveillance video and / or information provided by the traffic system.

[0119] S102. Based on the key information, determine whether the following preset conditions are met:

[0120] The driving direction information of the lanes in the road intersection scenario includes: the driving direction of the first lane and the driving direction of the second lane, wherein the first lane supports at least one driving direction, the second lane supports at least two driving directions, and both the first lane and the second lane support going straight; the driving direction supported by the second lane also includes turning right;

[0121] For example, in the scenario described above, the first lane is a straight-ahead lane, and the second lane is a mixed lane for both straight-ahead and right-turn traffic.

[0122] The traffic light is green.

[0123] Additionally, it should be noted that although the technical problem solved by the embodiments of this application is to improve the traffic efficiency of right-turning vehicles in a mixed straight-ahead and right-turn lane, and the corresponding description is based on the second lane as a mixed straight-ahead and right-turn lane, the embodiments of this application do not restrict the driving direction of each lane. In some scenarios, vehicles in a mixed straight-ahead and left-turn lane may be allowed to turn left when the light is red in the straight-ahead direction. Therefore, the technical solution provided by the embodiments of this application is also applicable, and the right turn can be replaced with a left turn. The corresponding technical problem solved is to improve the traffic efficiency of left-turning vehicles in a mixed straight-ahead and left-turn lane.

[0124] S103. When the preset conditions are met, at a first moment before the traffic light changes from the current green light to the red light or the yellow light, control information is output to enable straight-going vehicles in the second lane to change lanes into the first lane, wherein the first moment is spaced from the moment the traffic light changes from the current green light to the red light or the yellow light by a first duration.

[0125] It should be noted that the control information output to enable straight-going vehicles in the second lane to change lanes into the first lane is not limited to being based on information such as virtual waiting lines or indicator screens. The output of this control information can be controlled in advance by adjusting the length of the first duration. It is not limited to judging whether the vehicle is about to reach the virtual waiting line. Of course, it can also be combined with the position of the virtual waiting line to issue control information before the vehicle reaches the virtual waiting line.

[0126] In addition, the output of control information is not limited to display on a screen. It can also be used to send individual reminders to vehicles through vehicle positioning and vehicle networking, so as to notify the vehicles to change lanes.

[0127] In some embodiments, the key information of the road intersection scene also includes: information on the virtual waiting line preset on the second lane, wherein the virtual waiting line is a virtual waiting line generated in advance on the first lane and the second lane in the road intersection scene image captured by the image acquisition device based on the virtual and real boundary line information between the first lane and the second lane;

[0128] The preset conditions also include:

[0129] The vehicles traveling straight in the second lane did not pass the virtual waiting line.

[0130] In some embodiments, the virtual waiting line is located at the intersection of the solid and dashed lines between the first lane and the second lane, and is perpendicular to the extension direction of the second lane.

[0131] In some embodiments, the key information of the road intersection scenario further includes: lane stop line information; wherein, the stop lines of each lane are consistent;

[0132] The control information is output at a first moment before the traffic light changes from the current green light to the red light or the yellow light. The first moment is spaced from the moment the traffic light changes from the current green light to the red light or the yellow light by a first duration. The first duration is determined based on the length of the solid line between the first lane and the second lane, and the average speed of vehicles passing through the second lane. The length of the solid line is the length of the solid line between the virtual waiting line and the stop line of the lane.

[0133] In some embodiments, the method further includes:

[0134] When the traffic light is red, at a second moment before the traffic light changes from red to green, control information is output to allow straight-going vehicles in the first lane and / or the second lane to pass through the first lane. The second moment is separated from the moment the traffic light changes from red to green by a second duration, and the first duration may be the same as or different from the second duration.

[0135] In some embodiments, the control information is output and displayed through a preset display screen.

[0136] The output is used to control vehicles traveling straight in the second lane to change lanes into the first lane, for example, the display screen updates the display message "Straight-going vehicles, please enter the first lane and wait".

[0137] The output is used to control information that allows straight-going vehicles in the first lane and / or the second lane to pass through the first lane, such as updating the display screen to show the instruction "Straight-going vehicles may enter the second lane".

[0138] The display screen is, for example, positioned near a virtual waiting line.

[0139] In some embodiments, the key information further includes: information on the virtual waiting line preset on the second lane, information on the stop line of the lane, and vehicle passage instruction information currently displayed on the preset display screen;

[0140] The method further includes:

[0141] When the display screen currently shows the vehicle passage instruction information that straight-going vehicles should enter the first lane to wait, and there is a target vehicle in the second lane that has passed the virtual stop line (for example, the rear of the vehicle passes the virtual stop line), the first image of the target vehicle is captured.

[0142] When the target vehicle passes the stop line (for example, when the front of the vehicle touches the stop line), a second image of the target vehicle is captured;

[0143] When the target vehicle passes through the preset virtual right-turn line at the intersection, the first and second images of the target vehicle are deleted; when the target vehicle passes through the preset virtual straight-ahead line or virtual left-turn line at the intersection, a third image of the target vehicle is captured, and the capture information of the target vehicle is reported. The capture information includes the first, second, and third images of the target vehicle. Of course, the capture information may also include other information, such as time, location, information displayed on the indicator screen, traffic light information, etc.

[0144] In summary, the technical solution provided in this application utilizes only road intersection scene information to indicate the passage lanes for straight-going vehicles entering the "straight + right-turn mixed lane." Specifically, when the straight-going light is red, it prohibits straight-going vehicles from stopping in the mixed lane waiting area to wait for the green light, thus resolving the issue of right-turning vehicles queuing. For straight-going vehicles that fail to follow the instructions and stop in the mixed lane waiting area, a violation capture method is provided to warn or penalize violating vehicles.

[0145] Accordingly, see Figure 11 On the control information display end, such as the information notification device side, an embodiment of this application provides a vehicle traffic control method, including:

[0147] S202. Output the control information before the traffic light changes from the current green light to the red light or yellow light.

[0148] In some embodiments, the straight-going vehicle does not pass through a preset virtual waiting line on the second lane. The virtual waiting line is a virtual waiting line generated in advance on the first lane and the second lane in the road intersection scene image captured by the image acquisition device based on the virtual and real boundary line information between the first lane and the second lane.
