[0050] According to records, the earliest traffic lights originated in the United Kingdom in the early 19th century. At that time, in York City in central England, red and green clothes represented different identities of women. Among them, women in red clothes meant that they were married, while women in green clothes meant that they were unmarried. Later, accidents of carriages running over people often occurred in front of the Parliament Building in London, so people were inspired by the red and green clothes. On December 10, 1868, the first member of the signal light family was born in the square of the Parliament Building in London.

[0051] With the development of cities and the popularization of transportation, traffic safety issues have become increasingly prominent. Many people ignore traffic safety rules during traffic participation, resulting in frequent accidents. The emergence of some new transportation tools and technologies has also caused differences in the conditions of traffic safety belts, and has also brought new challenges to some common problems, such as preventing red light running.

[0052] The traffic control system provided by the embodiment of the present application is as follows: Figure 1 As shown, the system includes a traffic signal for controlling a traffic light 1; the system also includes:

[0053] A plurality of blocking devices 2 are respectively arranged along the zebra crossing of each road near the intersection, and are connected one-to-one with the signal output terminals of the traffic signal, and are used to move to a position allowing vehicles to pass, or to a position preventing vehicles from passing, according to the traffic control signal of the traffic signal;

[0054] An image recognition device, connected to the controller, for photographing pedestrian movement information along the zebra crossing and vehicle movement information along the road, and sending the information to the controller;

[0055] A controller connected to the blocking device 2, used to output a first braking control signal when a collision is predicted based on pedestrian movement information and vehicle movement information; the first braking control signal is used to control the blocking device 2 of the corresponding road to move to a position that blocks the vehicle from passing;

[0056] Among them: the control priority of the brake control signal is greater than that of the traffic control signal.

[0057] It should be noted that, for ease of understanding, Figure 1 An exemplary display method of two one-way four-lane roads is adopted to more intuitively display the positional relationship between the barrier device 2 and the traffic light 1 as well as the lanes and zebra crossings.

[0058] Specifically, the traffic signal sends a control signal to the barrier device 2 according to a preset control cycle of controlling the traffic light 1, so as to control the barrier device 2 located on each road to have the same action cycle as the traffic light 1.

[0059] Furthermore, when the traffic light 1 on one of the roads is controlled by the traffic signal machine to be in a green light cycle, the blocking device 2 on the corresponding road may be in a state of allowing vehicles to pass; and when the traffic light 1 on one of the roads is in a green-red light cycle, the blocking device 2 on the corresponding road may be in a state of preventing vehicles from passing.

[0060] Specifically, the image recognition device may include multiple cameras, each camera is used to photograph a first preset length of road in each road, a zebra crossing set on the road, and a second preset length perpendicular to the zebra crossing and extending outside the zebra crossing.

[0061] Furthermore, the first preset length of the road includes at least the road between two stop lines marked on the road; the second preset length aims to obtain pedestrian movement information to predict whether pedestrians and vehicles will collide, and can be set during the implementation process.

[0062] In one embodiment, an intersection may include eight traffic lights (not shown in the figure), which are used to connect to eight signal output terminals of a traffic signal machine. Each traffic light at the above-mentioned intersection is used to control a road and is provided with a blocking device. The blocking devices are respectively connected to and controlled by the signal output terminals of the traffic signal machine connected to the traffic lights in a one-to-one correspondence.

[0063] In one embodiment, Figure 2 As shown, the image recognition device may include a plurality of cameras 3, which are respectively arranged on the main body of the hydraulic lifting device of each barrier device.

[0064] Specifically, when collecting data of a first preset length of road in any road through camera 3, since camera 3 is arranged on the barrier device, and the barrier device is arranged on the side of the zebra crossing of the road close to the intersection, the camera 3 on the barrier device cannot capture the pedestrian movement information of the zebra crossing where the barrier device is located. Therefore, the camera 3 set on the barrier device on the other side of the intersection of the same lane can capture the zebra crossing on this side.

[0065] Furthermore, when the cameras 3 on both sides of the intersection of the same road obtain corresponding images, the image recognition device can obtain a panoramic image of the entire road by superimposing or fusing the two images, and obtain pedestrian movement information and vehicle movement information based on the panoramic image.

[0066] The above-mentioned traffic control system can execute the control signal of the traffic signal through the blocking device, so as to enforce traffic control through the blocking device when the traffic signal controls the red light to instruct people to pass, so as to avoid the occurrence of traffic accidents; it can also obtain the movement information of pedestrians and vehicles through the image recognition device, and judge whether there are pedestrians crossing the road when the blocking device allows vehicles to pass through the pedestrian movement information and vehicle movement information, and protect pedestrians by lowering the blocking device to a position that blocks vehicles from passing when a collision is predicted, thereby effectively improving the control effect through compulsory control measures.

[0067] In an exemplary embodiment, the traffic control system further includes:

[0068] A sound collection device is connected to the controller and is used to collect sound information of special vehicles and send it to the controller; the special vehicles include police vehicles or ambulances; the sound information includes sound direction and sound distance;

[0069] The controller is also used to predict the sending cycle of the traffic control signal corresponding to the road where the special vehicle is located according to the sound direction, and predict the arrival time of the special vehicle at the intersection according to the sound distance, and is also used to send a second braking control signal to the blocking device when it is judged according to the sending cycle and the arrival time that the corresponding blocking device is in a position to block the vehicle when the special vehicle arrives at the intersection; the second braking control signal is used to control the blocking device to move to a position allowing the vehicle to pass;

[0070] Wherein: the control priority of the first braking control signal is greater than that of the second braking control signal, and the control priority of the second braking control signal is greater than that of the traffic control signal.

[0071] Specifically, when special vehicles are performing emergency tasks, they usually turn on their sirens to prompt road users to give way. Therefore, the sound information emitted by them can be acquired and identified through the sound collection device. Big data training or other known means can be used to enable the sound collection device to effectively identify the sound direction and sound distance of the special vehicle through sound.

[0072] Specifically, when the controller recognizes the sound information of the special vehicle and determines the direction of the sound, it can determine which road the barrier device installed on should give way to the special vehicle through action.

[0073] Furthermore, the time when the special vehicle arrives at the blocking device is obtained by judging the distance of the special vehicle, and then the blocking device is judged to be in a state of allowing the vehicle to pass or blocking the vehicle to pass at the time of the arrival of the special vehicle according to the control cycle of the traffic signal received by the blocking device, and when the special vehicle is in a position to block the vehicle from passing when it arrives at the intersection, a second braking control signal is sent to the blocking device.

[0074] Furthermore, the control priority of the second brake control signal is lower than that of the first brake control signal, so that when the pedestrian does not cross the zebra crossing, the barrier device continues to protect the pedestrian to avoid collision, and after the pedestrian crosses the zebra crossing, the special vehicle is given way as soon as possible. It is understandable that the special vehicle has its own warning lights and sirens, and pedestrians will give way as soon as possible after seeing them, but since there may be special circumstances where pedestrians do not give way as soon as possible, the barrier device is controlled with the protection of pedestrians as the first priority.

[0075] In addition, in the case where no pedestrians cross the road, if the blocking device is in a state of blocking vehicles from passing according to the control of the traffic signal, when a special vehicle arrives, the blocking device gives way to the special vehicle based on the second brake control signal.

[0076] In one embodiment, Figure 2 As shown, the barrier device further includes a solar panel 4, which is disposed on the top of the barrier device to provide energy for the barrier device.

[0077] For example, the solar panel 4 uses pyrene-based materials to convert solar energy into electrical energy through the photovoltaic effect, and stores the electrical energy through the battery function, thereby realizing the storage and utilization of solar energy and storing the electrical energy generated during the day or on sunny days for use when needed.

[0078] In one embodiment, Figure 2 As shown, the sound collection device may include a plurality of sound collection units 5, each of which is respectively arranged on each barrier device, for analyzing the sound distance and sound direction of a special vehicle respectively, and sending them to the controller for fusion judgment.

[0079] Specifically, the sound can be collected according to each sound collection unit 5, and the direction of the sound can be determined according to the sound intensity collected by each sound collection unit 5. Then, the correspondence between the intensity of the sound and the distance can be further trained and analyzed by establishing a model, so as to finally realize the acquisition of the sound direction and sound distance by the sound collection device.

[0080] In an exemplary embodiment, the traffic control system further includes:

[0081] A plurality of indicator lights are arranged on the barrier device in a one-to-one correspondence and connected to the controller, and the indicator lights are used to flash in a preset flashing mode when receiving a first braking control signal or a second braking control signal corresponding to the barrier device; the preset flashing mode is used to instruct pedestrians to pay attention to avoidance;

[0082] The buzzer is connected to the controller and is used to sound according to a preset sounding mode when receiving the first brake control signal or the second brake control signal; the preset sounding mode is used to instruct pedestrians and vehicles to pay attention.

[0083] Specifically, the indicator light may be a yellow warning light to be distinguished from a police warning light.

[0084] Specifically, when the blocking device is braked, it means that the blocking device will not operate according to the predetermined operating rules; in this case, the indicator light should be used to remind pedestrians to pay attention and avoid.

[0085] On the other hand, due to the complex environment of the intersection, only the indicator lights are used to alert pedestrians at the zebra crossing. Participants on other roads cannot observe the indicator lights in time when turning right, etc. Therefore, a buzzer can be used to remind all traffic participants at the entire intersection to pay attention and avoid traffic accidents.

[0086] In an exemplary embodiment, Figure 3 As shown, the barrier device includes:

[0087] A plurality of barrier ropes 24 of the same width as the road;

[0088] Two sets of support structures are vertically arranged on both sides of the road to form installation stations for installing barrier ropes 24; each barrier rope 24 is installed at an equal distance at the installation station;

[0089] The hydraulic lifting device 22 is transmission-connected to the supporting structure and connected to the controller.

[0090] Specifically, the barrier rope 24 may be made of a material including high strength and wear resistance;

[0091] For example, the barrier cord 24 may be made of polyester fiber.

[0092] Specifically, the support structure is configured to be connected to a transmission mechanism within the hydraulic lifting device 24 .

[0093] The second aspect of the present application also provides a traffic control method, which is applied to a controller in a traffic control system as provided in the first aspect of the present application, such as Figure 4 As shown, the method includes the following steps 202 to 204.

[0094] in:

[0095] Step 202: receiving pedestrian movement information captured by an image recognition device along a zebra crossing and vehicle movement information captured along a road.

[0096] Specifically, the pedestrian movement information captured along the zebra crossing may include pedestrian movement information at both ends of a vertical extension line of the zebra crossing and pedestrian movement information on the zebra crossing.

[0097] Further, the vehicle movement information photographed along the road may include an extension line between vehicle stop lines on both sides of an intersection on a road and vehicle movement information between the vehicle stop lines.

[0098] Step 204, outputting a first braking control signal when a collision is predicted based on pedestrian movement information and vehicle movement information; the first braking control signal is used to control the blocking device of the corresponding road to move to a position that blocks vehicles from passing; the control priority of the first braking control signal is greater than the traffic control signal output by the traffic signal machine for controlling the blocking device to move to a position that allows vehicles to pass, or to a position that blocks vehicles from passing.

[0099] In an exemplary embodiment, Figure 5 As shown, the pedestrian movement information includes the number of pedestrians and the pedestrian position of each pedestrian at a preset time interval, and the method further includes the following steps 302 to 306. Among them:

[0100] Step 302, obtaining pedestrian movement information on a road corresponding to a target blocking device; the target blocking device includes a blocking device that moves from a position that blocks vehicle passage to a position that allows vehicle passage.

[0101] Step 304 : predicting the movement trend of the corresponding pedestrian based on the pedestrian position at the preset time interval.

[0102] Specifically, pedestrian images can be captured multiple times at preset time intervals, and the pedestrian's movement trend can be predicted based on the pedestrian images when the blocking device moves from a position that blocks vehicles from passing to a position that allows vehicles to pass, so as to determine whether the pedestrian intends to run a red light.

[0103] Step 306: If it is determined based on the movement trend that the pedestrian begins to cross the zebra crossing, a prediction result of a collision is obtained.

[0104] If the pedestrian intends to run a red light, a prediction result of a collision is given, and the blocking device is timely controlled through a first braking control signal to protect the pedestrian.

[0105] In an exemplary embodiment, Figure 6 As shown, the vehicle movement information includes the number of vehicles and the vehicle position of each vehicle in the corresponding time interval, and the method further includes the following steps 402 to 404. Among them:

[0106] Step 402, if at the time point when the target blocking device moves from the position that blocks the passage of vehicles to the position that allows the passage of vehicles, the pedestrian position is identified as being on the zebra crossing based on the pedestrian movement information, then the pedestrian position of the corresponding pedestrian at a preset time interval and the vehicle position of each vehicle before the stop line at a preset time interval are obtained respectively.

[0107] It is understandable that when the traffic light changes from green to red, pedestrians may not have completely crossed the road. In this case, the movement trends of vehicles and pedestrians are predicted at the same time to calculate the movement speeds of pedestrians and vehicles, and further determine whether pedestrians can leave the zebra crossing before the vehicle reaches it.

[0108] Step 404, whether there is a time node at which the distance between the pedestrian and the vehicle is less than a first preset value among the time nodes of the time interval; if so, a prediction result of the occurrence of a collision is obtained.

[0109] Specifically, in the process of determining whether a pedestrian can leave the zebra crossing before a vehicle reaches the zebra crossing, a first preset distance needs to be reserved between the pedestrian and the vehicle as a safety distance to avoid special circumstances.

[0110] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0111] Based on the same inventive concept, the embodiment of the present application also provides a traffic control device for implementing the above-mentioned traffic control method. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above-mentioned method, so the specific limitations in one or more traffic control device embodiments provided below can refer to the above-mentioned limitations on a traffic control method, and will not be repeated here.

[0112] In a third aspect, the present application provides a traffic control device 700, such as Figure 7 As shown, the device comprises:

[0113] The receiving module 701 is used to receive the pedestrian movement information captured by the image recognition device along the zebra crossing and the vehicle movement information captured along the road;

[0114] The output module 702 is used to output a first braking control signal when a collision is predicted based on pedestrian movement information and vehicle movement information; the first braking control signal is used to control the blocking device of the corresponding road to move to a position that blocks the passage of vehicles; the control priority of the first braking control signal is greater than the traffic control signal output by the traffic signal machine, which is used to control the blocking device to move to a position that allows vehicles to pass, or to a position that blocks the passage of vehicles.

[0117] The prediction module is used to predict the movement trend of the corresponding pedestrian based on the pedestrian position at a preset time interval; if the pedestrian is judged to start crossing the zebra crossing based on the movement trend, a prediction result of the occurrence of a collision is obtained.

The acquisition module is further used to, if at a time node when the target blocking device moves from a position that blocks vehicle passage to a position that allows vehicle passage, it is identified according to the pedestrian movement information that the pedestrian is located on the zebra crossing, then the pedestrian position of the corresponding pedestrian at a preset time interval and the vehicle position of each vehicle before the stop line at a preset time interval are respectively acquired;

[0119] The traffic control device also includes: a judgment module, which is used to judge whether there is a time node in each time node of the time interval when the distance between the pedestrian and the vehicle is less than a first preset value; if so, a prediction result of the occurrence of a collision is obtained.
