Description

Traffic control system for managing vehicle around crosswalk}

The present invention relates to a traffic control system for vehicle management in a crosswalk, and more particularly, to prevent a traffic accident in advance by providing warning information about a traffic violation vehicle around the crosswalk through an electric signboard. It relates to a traffic control system for vehicle management at crosswalks that helps prevent traffic congestion due to tail-biting in advance by identifying expected vehicles and providing relevant information through electronic signage.

Recently, traffic accidents due to non-observance of the speed limit or non-compliance with the stop line, and traffic congestion due to non-compliance with the stop line and tail biting are increasing near crosswalks.

Accordingly, a traffic control system for preventing traffic accidents is being developed. Most of these traffic control systems measure the speed of a vehicle approaching the crosswalk through the camera, and the speed of the vehicle measured through the camera. is displayed on a display installed near the crosswalk.

Such an existing traffic control system can provide a warning to the driver by displaying the color of the speed in red through the display when the speed of the vehicle exceeds the prescribed speed, which can induce the driver to reduce the speed of the vehicle.

However, the existing traffic control system cannot provide a warning about speed deceleration by specifying the vehicle through the display when a specific vehicle among a plurality of vehicles entering the crosswalk is driving over the prescribed speed. There are frequent cases of driving without recognizing that the displayed speed is the speed of the vehicle, and ignoring the warning through such a display.

In addition, the existing traffic control system raises the driver's awareness and complies with the stop line by raising the awareness of the driver and reporting the offending vehicle by providing an image of the violation case generated by shooting a vehicle that violates the stop line or biting through the camera to the central server. induces and prevents tail biting.

However, this method only induces the driver to be aware of the stop line observance and crackdown on tail-biting violations. As a result, the operation of the existing traffic control system depends only on the driver's consciousness and provides a direct warning to induce the driver. Since it is not provided, it is inevitable that the driver is frequently unaware of the violation if there is no direct warning about enforcement.

Accordingly, there is a problem that cannot prevent traffic accidents and traffic congestion due to intrusion of the stop line and tail biting in advance only with the existing traffic control system that expects drivers to drive with caution at all times without specifying and warning the vehicle directly. have.

In addition, despite the frequent occurrence of cases in which the driver inadvertently violates the tail biting by getting caught at a stop signal while the preceding vehicle passing through the crosswalk is stopped by the preceding vehicles, the existing traffic control system prevents the driver from being bitten. There is a problem in that traffic congestion cannot be prevented in advance because it does not provide any information about possible situations.

Therefore, it is necessary to develop a system that can support efficient traffic control by proactively preventing traffic accidents and traffic congestion in advance by providing a direct warning to vehicles that may cause traffic accidents and traffic congestion in these crosswalks. is becoming

The traffic signal controller 10 transmits a traffic light control signal to the traffic light 1 for controlling the traffic light 1 for guiding whether the crosswalk can be walked or whether the vehicle can pass for the crosswalk. , a traffic signal of the traffic light 1 may be controlled, and the traffic light control signal may also be transmitted to the control module 100 .

The control module 100 may identify a traffic signal currently displayed on the traffic light 1 based on the traffic light control signal received from the traffic signal controller 10, and the current traffic signal is a walking enable signal for a crosswalk. It can be determined whether or not

At this time, the traffic light 1 may be a walking traffic light for guiding whether a pedestrian can walk in a crosswalk or a vehicle traffic light (or a driver's traffic light) for guiding whether a vehicle passes the crosswalk, and the control module 100 ), preset setting information for whether walking is possible for each of a plurality of different traffic signals that can be displayed in the traffic light 1 is set in advance, and the control module 100 controls the traffic light according to the traffic light control signal based on the setting information.

As shown, the camera unit 20 may generate an image of a vehicle approaching the crosswalk and provide it to the control module 100 .

In addition, the traffic signal controller 10 may transmit the traffic light control signal to the control module 100 when generating a traffic light control signal for controlling a traffic signal of a traffic light guiding whether a crosswalk can be walked (S1) .

Also, the control module 100 may identify the current traffic signal displayed on the traffic light based on the traffic light control signal received from the traffic signal controller 10 .

Also, the control module 100 may compare the current traffic signal with the preset setting information to determine whether the current traffic signal is a walkable signal for the crosswalk.

For example, when the traffic light controlled by the traffic signal controller 10 is a walking traffic light, the control module 100 displays the current traffic signal according to the traffic light control signal received from the traffic signal controller 10 is displayed on the walking traffic light. If it is a green walking signal, it can be determined that the corresponding walking signal is a walkable signal, and if the current traffic signal displayed on the walking traffic light according to the traffic light control signal is a red walking prohibition signal, it is determined that it is not a walkable signal or walking is prohibited signal can be judged.

In addition, the control module 100 may operate to detect a vehicle that violates the stop line when the current traffic signal is a walkable signal (S2).

To this end, the control module 100 performs image analysis on the image received from the camera unit 20, and identifies one or more objects corresponding to one or more vehicles appearing in the image through the image analysis. It can be tracked (S3).

In this case, various well-known image analysis algorithms for object identification and object tracking may be set and applied to the control module 100 , and these image analysis algorithms are configured in the control unit or the image analysis unit configured in the control module 100 . can be

In addition, the control module 100 controls the current traffic signal for each one or more objects corresponding to one or more vehicles identified through image analysis of the image received from the camera unit 20 in a state in which the current traffic signal is a walkable signal. It is possible to determine whether the stop line shown in the image has been violated.

In this case, the control module 100 may identify a stop line area corresponding to a stop line in the image or a stop line area corresponding to the image may be preset in the control module 100 .

Accordingly, the control module 100 may detect a specific object corresponding to a vehicle that violates a stop line among the one or more objects identified in the image in a state in which the current traffic signal is a walkable signal (S4).

For example, the control module 100 detects an object area for each of the one or more objects from the image, compares the object area with the stop line area, and sets a specific object corresponding to the object area overlapping the stop line area with the stop line. It can be detected as an intruding vehicle.

In addition, the control module 100 may generate a still image of the specific object by extracting it from the image when detecting a specific object corresponding to the vehicle that violates the stop line (S5).

For example, the control module 100 identifies the object area of the specific object, crops the object area from the image, or makes a still image of a preset reference size based on the object area of the specific object. A still image including a specific object may be generated by cropping the image.

In addition, the control module 100 may identify the license plate of a specific vehicle corresponding to the specific object through image analysis from the still image or the image when detecting a specific object that violates the stop line, and from the identified license plate Through image analysis, the vehicle number information of the specific vehicle may be recognized and vehicle number information may be generated (S5).

In addition, the control module 100 generates first expression information including the specific vehicle-related vehicle number information generated according to the detection of a specific object that violates the stop line, the still image, and a preset stop line violation message (S6) It can be transmitted to the electronic signboard control terminal 40 (S12).

In this case, the stop line violation message may be a message such as "Let's obey the stop line."

In addition, the electronic sign control terminal 40 transmits the first expression information to the electric sign 30 when receiving the first expression information from the control module 100 and displays the first expression information through the electric sign 30 Through this, the driver of a specific vehicle that has violated the stop line is displayed through the electronic display 30, his/her vehicle through the still image of his/her specific vehicle, vehicle number information of the specific vehicle, and the stop line violation message. It is possible to induce not to violate the stop line by providing it to recognize that it is a vehicle that violates the stop line, and through this, it is possible to prevent a traffic accident caused by a vehicle violating the stop line in advance.

At this time, the control module 100 determines a stop line through image analysis of the image received from the camera unit 20 from the time the traffic light control signal for the walkable signal is received until the next traffic light control signal is received. The first expression information may be generated for each one or more objects corresponding to one or more intrusive vehicles and transmitted to the electronic signboard control terminal 40 .

In addition, when the plurality of first expression information received from the control module 100 is plural, the electric sign control terminal 40 alternately (alternately or alternately) at a preset time interval for the plurality of first expression information (30) can be output and displayed.

Alternatively, the electronic signboard control terminal 40 may align the plurality of first expression information and display them all through the electric signboard 30 .

In addition, the control module 100 may set the object for which the first expression information is generated as the object of interest in the image and track the object of interest through image analysis, and when the object of interest does not invade the stop line Deletion request information including vehicle number information of the object of interest for preventing the first expression information corresponding to the object of interest from being output through the electric sign 30 may be transmitted to the electric sign control terminal 40 .

As an example, the control module 100 generates first expression information for a specific object and transmits it to the electric sign control terminal 40, and then based on the first expression information, the specific object can be set as an object of interest, , when the vehicle corresponding to the object of interest does not invade the stop line region by reversing as a result of image analysis of the image received from the camera unit 20, vehicle number information according to the first expression information set in response to the object of interest The deletion request information included therein may be transmitted to the electronic signboard control terminal 40 .

At this time, the control module 100 matches the vehicle number information included in the first expression information with the object of interest identified in the image and sets (tagging) the object of interest, so that the vehicle number information included in the first expression information can be used as tag information.

Accordingly, the electronic sign control terminal 40 deletes the first expression information corresponding to the vehicle number information included in the deletion request information when the deletion request information is received, so that the deleted first expression information is the electric sign 30 You can make it invisible via .

Meanwhile, when the current traffic signal is not a walkable signal or a walking prohibition signal, the control module 100 may operate to detect a speeding vehicle among vehicles approaching the crosswalk (S2).

Accordingly, the control module 100 may identify one or more vehicles and one or more objects respectively corresponding to one or more vehicles appearing in the image through image analysis as described above in the image received from the camera unit 20 (S7) , by tracking the one or more objects, it is possible to calculate the location of the vehicle and the speed of the vehicle for each object (S8).

In addition, the control module 100 selects a specific object corresponding to a specific vehicle having a speed greater than or equal to a preset preset speed among vehicles approaching the crosswalk, a speed calculated for the specific object and a preset reference value corresponding to the prescribed speed can be identified based on (S9).

In addition, the control module 100 may generate the vehicle number information by identifying the license plate of the specific object through image analysis of the image for the specific object, which is a vehicle violating the regulation speed above a preset reference value. (S10).

In addition, the control module 100 generates second expression information including the vehicle number information obtained for the specific object, speed information of the specific object, and preset speed information for the preset speed (S11) It can be transmitted to the electric sign control terminal 40 (S12).

In addition, the electric sign control terminal 40 transmits the second display information to the electric sign 30 when receiving the second display information from the control module 100 and transmits the second display information through the corresponding electric sign 30 . can be displayed and displayed, and a driver driving a vehicle that violates the regulation speed approaching the crosswalk checks his or her license plate number and the second display information about the speed violation through the electronic sign 30 to check the regulation speed at the crosswalk. may be encouraged to comply.

At this time, the control module 100 analyzes the image of the image received from the camera unit 20 from the time when a traffic light control signal for a traffic signal other than the walkable signal is received until the next traffic light control signal is received. The second expression information may be generated for each one or more objects corresponding to one or more vehicles violating the prescribed speed through , and transmitted to the electric sign control terminal 40 .

At this time, when the plurality of second expression information received from the control module 100 is the plurality of second expression information, the electric sign control terminal 40 alternately (alternately or alternately) at a preset time interval (alternately or alternately) the electric sign board (30) can be output and displayed.

Alternatively, the electric sign control terminal 40 may align the plurality of second expression information and display all of them through the electric sign 30 .

In the above-described configuration, the control module 100 may transmit the signal light control signal to the electric sign control terminal 40 upon receiving the traffic light control signal.

In the above-described configuration, the control module 100 identifies all vehicles approaching the crosswalk (to pass the crosswalk) and all objects respectively corresponding to them from the image regardless of whether or not the speed is violated, and the identified The second expression information including vehicle number information, speed information, and prescribed speed information for each object may be generated and transmitted to the electronic signboard control terminal 40 .

In addition, the electric sign control terminal 40 can display the second display information received every time the second display information is received from the control module through the electric sign 30, and the electric sign control terminal 40 also has a prescribed speed. When receiving the second expression information set in advance and the speed information included in the second expression information exceeds the preset speed, the second expression information related to the regulation speed violation including the speed information exceeding the prescribed speed is displayed on the electronic board 30 ), the speed information included in the second expression information related to the regulation speed violation is displayed through the electric sign 30 in red, and the vehicle number information included in the second expression information related to the regulation speed violation is displayed through the display board to blink. (30) can be displayed.

In addition, the electronic signboard control terminal 40 may preset a plurality of different display modes corresponding to a plurality of different traffic light control signals, respectively.

Accordingly, when the traffic light control signal is the walkable signal, the electronic signboard control terminal 40 switches to the first display mode among the plurality of display modes, and when the first expression information is received, the first expression information is After dividing the display area of the electric sign 30 into a plurality of division areas according to the corresponding first display mode, the vehicle number information included in the first expression information, the still image, and a preset stop line violation message are respectively displayed. The display may be displayed in the divided areas that are different according to the first display mode.

In addition, the electric sign control terminal 40, when the traffic light control signal is not a walkable signal, after switching to a second display mode among the plurality of display modes, corresponds to the second expression information when receiving the second expression information After dividing the display area of the electric sign 30 into a plurality of divided areas according to the second display mode being It can be displayed in the different divided areas according to the display mode.

In the above configuration, the electronic signboard control terminal 40 transmits preset speed information and a preset guide message while the first expression information is not received from the control module 100 in the state in which the first display mode is set. It can be expressed through the electric sign 30 .

In this case, the guide message may include various messages such as "child protection area", "illegal parking, stopping".

Through the above-described configuration, the present invention determines whether the current traffic signal currently displayed on the traffic light is a walkable signal based on the traffic light control signal provided from the traffic signal controller 10, and a vehicle that invades a stop line in a walkable signal state. By displaying the expression information including the still image for the specific vehicle through the electronic sign board 30, the driver of the vehicle that violates the stop line can be made aware that the stop line is being violated, so that the vehicle concerned about the accident due to the stop line violation can be directly detected. In addition to being able to control the vehicle by providing a warning by specifying a vehicle approaching the crosswalk at speeding speed in the state of a pedestrian prohibition signal, the driver of the specified vehicle can be directly controlled by inducing attention to driving. Traffic accidents can be effectively prevented in advance through direct control of vehicles that are concerned about accidents at crosswalks due to speeding or speeding.

In particular, the present invention specifies the vehicle number of a vehicle that violates the stop line or a speeding vehicle through the electric sign 30 and displays it through the electric sign 30, so that the driver of the vehicle corresponding to the corresponding vehicle number through the electric sign 30 Since a direct warning can be provided to easily recognize that the vehicle is violating traffic laws, it can support direct control of the driver of the vehicle.

On the other hand, the control module 100 can prevent traffic congestion in advance by preventing the tail biting of the vehicle near the crosswalk, which will be described in detail with reference to FIGS. 4 and 5 .

As shown, the control module 100 may calculate the signal period of the traffic light based on the traffic light control signal received from the traffic signal controller 10 .

For example, the control module 100 is configured to provide a walkable signal (green of a pedestrian traffic light) in relation to a traffic light controlled by the traffic signal controller 10 based on a traffic light control signal received from the traffic signal controller 10 . A signal period for each traffic signal of at least one of a signal or a red signal of a traffic light for a vehicle), a walking prohibition signal (a red signal of a pedestrian traffic light or a green signal of a traffic light for a vehicle), and a caution signal (yellow signal) may be calculated.

In addition, the control module 100 performs image analysis on the image received from the camera unit 20 when the traffic light control signal received from the traffic signal controller 10 is not a walkable signal or a walking prohibition signal. The vehicle location may be tracked for each of the identified one or more vehicles and one or more objects corresponding to each other, and the vehicle speed may be calculated for each object according to the location tracking for each object.

In addition, the control module 100 identifies a stop line area (or stop line position) through the image analysis, and then performs tail biting based on the stop line area, the vehicle position for each object, the vehicle speed for each object, and the signal period. may detect the expected object, identify the license plate of the detected object, and then recognize the vehicle number from the identified number plate to generate vehicle number information.

In addition, the control module 100 transmits the third expression information including the vehicle number information generated according to the detection of the object expected to be tailed and a preset notification message for tail biting prevention in relation to the tail biting. It can be generated to correspond to the detected object and transmitted to the electronic signboard control terminal 40 .

In this case, the notification message may be a message such as "Stop at the stop line (or before the stop line)."

In addition, the electronic signboard control terminal 40 may transmit the third expression information to the electric sign 30 upon receiving the third expression information to display the third expression information through the electric sign 30 .

As an example for this, the control module 100 counts the time from the time of change to a traffic signal that is not a walkable signal or a traffic signal corresponding to a walking prohibition signal based on the traffic light control signal received from the traffic signal controller 10 . Thus, it is possible to determine in real time the remaining time until the signal is changed to a walkable signal according to the signal period.
