It may include an information server 200, a pedestrian terminal 300, and a vehicle-mounted terminal 400.

The enforcement device 100, traffic information server 200, pedestrian terminal 300, and vehicle-mounted terminal 400 may communicate with each other through the network 20. The network 20 refers to a connection structure that allows information exchange between nodes such as terminals and servers. Examples of such networks 20 include the 3rd Generation Partnership Project (3GPP) network, Long Term Evolution) network, 5G network, WIMAX (World Interoperability for Microwave Access) network, Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area) Network), wifi network, Bluetooth network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc., but are not limited thereto.

In the description of the embodiment of the present application, the traffic information server 200 is configured to receive information about a vehicle (regulation violation object) that violates the right turn-related regulations detected by the enforcement device 100 from the enforcement device 100. You can. By way of example, the traffic information server 200 may be a server for collecting various types of traffic situation information on the road, a server operated by the police to crack down on violations of laws by driving vehicles, etc., but is not limited thereto.

For example, the pedestrian terminal 300 includes a smartphone, a SmartPad, a tablet PC, etc., as well as a Personal Communication System (PCS), a Global System for Mobile communication (GSM), a Personal Digital Cellular (PDC), and a PHS (Personal Communication System). Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal It can be any type of wireless communication device, such as:

In addition, in the description of the embodiment of the present application, the vehicle-mounted terminal 400 is mounted on the vehicle of a subscriber who has subscribed to driver's insurance, such as a black box terminal, navigation module, high-pass module, or connected car mobility service module, and is used to drive the vehicle. It can be understood as a concept that broadly includes various devices that can collect driving information.

For example, among the vehicle-mounted terminals 400, the connected car mobility service module is mounted inside the vehicle to provide remote start services such as Blue Link and UVO, remote air conditioner control services, etc., and is used for other vehicles, traffic, and communications. It can refer to a terminal that communicates with infrastructure, pedestrian terminals, etc. in real time and helps driver convenience and traffic safety.

Additionally, according to the implementation example of the present application, the vehicle-mounted terminal 400 may refer to a user terminal (not shown) held by a driver or passenger riding in the vehicle.

Additionally, according to an embodiment of the present application, the enforcement device 100 may be provided on an infrastructure structure (not shown) provided at a predetermined intersection. In this regard, infrastructure structures (not shown) are, for example, Internet of Things (IoT) equipment, speed detectors, toll gate equipment, high-pass terminals, surveillance cameras, and signal controllers installed at the intersection, and communicate with vehicles. It can be understood as a concept that broadly includes various devices that can collect driving information on possible or adjacent roads and vehicles traveling on the road.

Hereinafter, with reference to FIGS. 2 and 3, the process for determining whether there is a violation of the regulations associated with temporary stopping when turning right (hereinafter referred to as 'first requirement') will be described.

Figure 2 is a conceptual diagram to explain the judgment process as to whether or not the first requirement is violated.

Referring to FIG. 2 , the control device 100 may identify a target vehicle 1 approaching through the surveillance target lane 11, which is a right-turn lane at the intersection, while the vehicle signal at the intersection is a stop signal.

For reference, in the description of the embodiment of the present application, the surveillance target lane 11 may mean the rightmost lane of the intersection.

According to an embodiment of the present application, the enforcement device 100 derives the lighting information of the traffic light structure 12 on the intersection associated with the driving of the target vehicle 1 from the image photographed to include the traffic light structure 12 at the intersection. It can be determined whether the vehicle signal is a stop signal. In this regard, the enforcement device 100 includes a camera module (not shown) for acquiring images reflecting various traffic conditions at the intersection including lighting information of the traffic light structure 12, or an infrastructure structure (not shown). ) The image may be acquired from separate camera modules 14a and 14b provided in the camera.

As another example, the enforcement device 100 obtains the lighting information of the traffic light structure at the intersection where the target vehicle 1 is located from the traffic light structure or a signal controller (traffic signal control device) provided at the intersection, thereby stopping the vehicle signal at the intersection. You can determine whether it is a signal or not.

Meanwhile, the enforcement device 100 monitors vehicles that have entered within a preset first distance (d ₁ ) along the monitoring target lane 11 from the stop line (L) of the intersection for violations of the first requirement. It can be identified as the target vehicle (1), which is the target object for the vehicle.

Illustratively, according to an embodiment of the present application, the first distance (d ₁ ) may be preset to a distance of 150 m from the stop line (L), but is not limited to this, and is not limited to the number of lanes at the intersection, the intersection It may be variable considering the traffic volume, speed limit of the road, weather (road surface condition), time of day, etc.

Additionally, the control device 100 may determine whether the first requirement associated with a temporary stop when turning right is violated based on speed change information of the identified target vehicle 1.

Specifically, the enforcement device 100 may detect the entry of the target vehicle 1 into the target area A, which is within a preset distance from the stop line L among the areas of the lane 11 to be monitored.

Figure 3 is a conceptual diagram showing the target area associated with the lane to be monitored and the determination of whether or not the first requirement is violated.

Referring to FIG. 3, the target area (A) is an area of the surveillance target lane 11 whose separation distance from the stop line (L) is the second distance (d ₂ ), and is the above-mentioned first distance (d ₁ ). is a reference distance set to detect the presence of a target vehicle (1) approaching the intersection through the surveillance target lane (11), while the second distance (d2) is a target vehicle (1) that is detected (identified). This may be a distance for specifying the target area (A) for specifically determining whether or not the first requirement is violated, as an area located immediately before making a right turn.

In other words, the second distance (d ₂ ) may be set to a smaller value than the first distance (d ₁ ). For example, the second distance (d ₂ ) is preset with respect to the first distance (d ₁ ). It may be determined as a value multiplied by a ratio (for example, 1/10, etc.), but is not limited to this. As another example, the second distance (d ₂ ) is determined by a fixed standard distance such as 15m, or, depending on the implementation of the present invention, the number of lanes at the intersection, the traffic volume at the intersection, the speed limit on the road, and the weather (road surface condition) ), it may be variable considering the time zone, etc.

Additionally, the enforcement device 100 may obtain speed change information about the target vehicle 1 entering the target area A. In other words, the enforcement device 100 tracks the change in speed of the target vehicle 1 over time from the time the target vehicle 1 enters the target area A, and creates a time series representing the change in speed of the target vehicle 1. You can obtain an enemy sequence.

Illustratively, the enforcement device 100 acquires speed change information of the target vehicle 1 based on a speed measurement sensor (e.g., lidar sensor, laser detector, etc.) provided at the intersection or by a camera module. Speed change information of the target vehicle 1 may be obtained through analysis of the acquired image information.

In addition, the control device 100 determines whether the first requirement is violated by determining whether the target vehicle 1 maintains a stopped state for more than a preset reference time based on the obtained speed change information of the target vehicle 1. It can be figured out.

More specifically, the enforcement device 100 may determine that the first requirement is violated when the target vehicle 1 passes the stop line (L) without reaching a stop state or remains stopped for less than a preset reference time. there is.

In this regard, the stopped state means a state in which the speed of the vehicle is 0 (including a state in which the speed can be considered to be practically 0), and the first requirement is that the vehicle must stop temporarily before turning right according to the signal at the intersection. Since it corresponds to the requirements of Article 25 of the Road Traffic Act, the enforcement device 100 determines whether the first requirement is violated based on the speed change information of the target vehicle 1 and states that the vehicle is stopped for more than a preset reference time. You can monitor whether a right turn is made after maintaining (pause).

Meanwhile, in the description of the embodiment of the present application, the reference time, which is the standard for determining whether the first requirement is violated, takes into account the driver's perception reaction process (PIEV) and allows the driver of the vehicle to respond to unexpected situations that may occur at an intersection. The length can be determined by considering the time required to respond. For example, the standard time may be set to 2.5 seconds, but is not limited to this. The standard time may be determined by the number of lanes at the intersection, traffic volume at the intersection, speed limit on the road, weather (road surface condition), time zone, and related laws ( It may be subject to change in consideration of the guidelines specified in the regulations, etc.

Additionally, if the enforcement device 100 determines that the target vehicle 1 violates the first requirement, the enforcement device 100 may transmit vehicle information of the target vehicle 1 to the traffic information server 200. In this regard, the enforcement device 100 is a vehicle that includes at least one of a report image captured to include the target vehicle 1 that violates the first requirement and vehicle number information of the target vehicle 1 identified from the report image. Information can be transmitted to the traffic information server 200, and the type and transmission method of vehicle information of the target vehicle 1 transmitted to the traffic information server 200 in accordance with the violation of the requirements in this way are determined by violation of the second requirement described later. It can be equally applied to .

In this regard, the control device 100 may be provided with reading means for identifying the vehicle number information of the target vehicle 1 from the report image, but is not limited thereto, and the control device 100 may only use the report image. A method of operating to transmit to the information server 200 and reading vehicle number information on the traffic information server 200 from the received tip image may also be considered.

In addition, according to an embodiment of the present application, if the control device 100 determines that the target vehicle 1 violates the first requirement, the control device 100 sends a warning to the vehicle for violation of regulations using the vehicle-mounted terminal 400 provided in the target vehicle 1. Warning/alarm signals can be transmitted accordingly. For example, the warning/alarm signal may include information about expected fines for violation of the first requirement.

Hereinafter, with reference to FIG. 4, the process for determining whether there is a violation of the regulations related to pedestrian protection when turning right (hereinafter referred to as 'second requirement') will be described.

Figure 4 is a conceptual diagram to explain the judgment process as to whether or not the second requirement is violated.

Referring to FIG. 4, the enforcement device 100 is a crosswalk provided around the surveillance target lane 11 (for example, a crosswalk disposed in front of the stop line L (vehicle travel direction) of the surveillance target lane 11. When the signal (such as a crosswalk placed on a sidewalk and/or a lane to be entered after turning right through the surveillance target lane 11) is a walking signal, the entry of the target vehicle 1 into the crosswalk can be detected.

According to an embodiment of the present application, the enforcement device 100 receives lighting information of the pedestrian traffic light structures 13a and 13b on an intersection associated with pedestrian traffic at the intersection from images captured to include the pedestrian traffic light structures 13a and 13b. By deriving it, it is possible to determine whether the crosswalk signal at an intersection is a pedestrian signal. In this regard, the camera module (not shown) of the enforcement device 100 or the camera modules 14a and 14b provided separately from the enforcement device 100 may capture images reflecting the pedestrian traffic light structures 13a and 13b. there is.

As another example, the control device 100 transmits the lighting information of the pedestrian traffic light structures 13a, 13b at the intersection where the target vehicle 1 is located to the pedestrian traffic light structures 13a, 13b or a signal controller (pedestrian signal control) provided at the intersection. It is possible to determine whether a crosswalk signal is a walking signal by obtaining it from a device, etc.

Additionally, the control device 100 may determine whether the second requirement related to pedestrian protection when turning right is violated based on pedestrian location information of the pedestrian 2 located on the crosswalk.

Specifically, the enforcement device 100 detects that the target vehicle 1 has entered the crosswalk, and the pedestrian 2 is in a preset direct collision at the reference time based on the pedestrian location information of the pedestrian 2 at the reference time. If located in area 21, it can be determined that the second requirement is violated.

Meanwhile, the control device 100 detects that the pedestrian (2) is located on the crosswalk at the reference time when the target vehicle (1) is detected to have entered the crosswalk, but the pedestrian (2) is located on the crosswalk based on the pedestrian location information. If it is determined to be located in the indirect conflict area (22), which is an area other than the conflict area (21), it can be determined that the second requirement has not been violated.

In this regard, the direct conflict area 21 of the crosswalk is the area within the crosswalk relatively close to the lane 11 to be monitored, and the indirect conflict area 22 is the area within the crosswalk relatively distant from the lane 11 to be monitored. As an area, unlike the indirect conflict area (22), if a vehicle attempts to turn right while a pedestrian is located in the direct conflict area (21), the vehicle may pose a threat to the pedestrian, so inside the direct conflict area (21) The target vehicle (1) that enters the crosswalk while the pedestrian (2) is located may be judged to have violated the second requirement.

Meanwhile, according to an embodiment of the present application, as shown in FIG. 4, the direct conflict area 21 and the indirect conflict area 21 are located far from the surveillance target lane 11 based on the walking direction in which the pedestrian crosses the crosswalk. Half of the area may be set as an indirect conflict area (21), and the other half area relatively close to the surveillance target lane (11) may be set as a direct conflict area (22), but is not limited to this, and may be set as a direct conflict area (21). And the area setting (for example, setting the area ratio, etc.) of the indirect conflict area 22 may be set in consideration of various environmental factors of the intersection.

For example, the area ratio of the direct conflict area (21) and the indirect conflict area (22) is determined by the number of lanes at the intersection, traffic volume at that intersection, speed limit on that road, weather (road surface conditions), time of day, and accident frequency at that intersection. , it may be variable considering the number of pedestrians waiting to cross the crosswalk, the speed of pedestrians moving on the crosswalk, etc.

More specifically, with regard to setting the area ratio of the direct conflict area 21 and the indirect conflict area 22 in relation to the movement speed of pedestrians, for example, when it is identified that there is a pedestrian running at high speed and crossing the crosswalk. The direct conflict area 21 may be set relatively wide.

In addition, if it is determined that the target vehicle 1 violates the second requirement, the enforcement device 100 may transmit vehicle information of the target vehicle 1 to the traffic information server 200, and the transmission process of this vehicle information can be performed equally as in the case of violation of the first requirement mentioned above.

In addition, according to an embodiment of the present application, if the control device 100 determines that the target vehicle 1 has violated the second requirement, the control device 100 detects a violation of the regulations with the vehicle-mounted terminal 400 provided in the target vehicle 1. Warning/alarm signals can be transmitted accordingly. For example, the warning/alarm signal may include information about expected fines for violation of the second requirement.

In addition, according to an embodiment of the present application, if the control device 100 determines that the target vehicle 1 violates the second requirement, the pedestrian located at the intersection (for example, crossing the crosswalk, or A danger notification signal can be transmitted to the pedestrian terminal 300 owned by a pedestrian (such as a pedestrian located in the conflict area 21) at the time. As an example, the danger notification signal may be transmitted together with vehicle information of the target vehicle 1 that violates the second requirement.

Figure 5 is a schematic configuration diagram of a right-turn vehicle control device according to an embodiment of the present application.

Referring to FIG. 5 , the enforcement device 100 may include an identification unit 110, a determination unit 120, and a communication unit 130. Also, referring to Figure 5, the identification unit 110 includes an access identification unit 111 and an entry identification unit 112, and the determination unit 120 includes a first determination unit 121 and a second determination unit ( 122) may be included.

The approach identification unit 111 can identify the target vehicle 1 approaching through the surveillance target lane 11, which is a right-turn lane at the intersection, while the vehicle signal at the intersection is a stop signal.

In addition, the entry identification unit 112 may detect the entry of the target vehicle 1 into the crosswalk when the signal of the crosswalk provided around the surveillance target lane 11 is a walking signal.

The first judgment unit 121 may determine whether the first requirement associated with a temporary stop when turning right is violated based on the speed change information of the target vehicle 1.

Specifically, the first judgment unit 121 detects the entry of the target vehicle 1 into a target area within a preset distance from the stop line L among the areas of the lane 11 to be monitored and sends the target vehicle 1 to the target vehicle 1. By obtaining the speed change information for the target vehicle 1 and determining whether the target vehicle 1 maintains the stopped state for more than a preset reference time based on the obtained speed change information of the target vehicle 1, whether the first requirement is violated is determined. It can be figured out.

At this time, the first judgment unit 121 may determine that the first requirement has been violated if the target vehicle 1 passes the stop line (L) without reaching a stop state or remains stopped for less than the standard time. .

Additionally, the second judgment unit 122 can determine whether the second requirement related to pedestrian protection when turning right is violated based on pedestrian location information of pedestrians located on the crosswalk.

Specifically, the second judgment unit 122 determines that the pedestrian (2) at the reference point is preset at a direct conflict area ( 21), the target vehicle (1) can be judged to have violated the second requirement.

If the communication unit 130 determines that the target vehicle violates at least one of the first requirement and the second requirement, the communication unit 130 may transmit vehicle information of the target vehicle 1 to the traffic information server 200.

According to an embodiment of the present application, the communication unit 130 sends vehicle information including at least one of a report image captured to include the target vehicle 1 and license plate number information of the target vehicle identified from the report image to a traffic information server ( 200), etc.
