Description

Pedestrian notification system when vehicle turns right}

The present invention relates to a technology capable of preventing a pedestrian traffic accident when a vehicle turns right at an intersection.

According to the current traffic laws, when a vehicle turns right at an intersection, the vehicle may pass through the right-turn crosswalk even if it is a green pedestrian signal for the crosswalk (hereinafter referred to as 'right-turn crosswalk') after the right turn, but in the process If you cause a personal accident, you will be held criminally responsible.

In order to solve this problem, there are cases where a right turn signal light is installed to display a pedestrian signal of a right turn crosswalk and provide a right turn vehicle driver. However, since the conventional right turn signal light only displays a walking signal for a right turn crosswalk, it is difficult to identify a pedestrian crossing without permission even with a red pedestrian signal.

In particular, when the driver does not know when the pedestrian signal of the right-turning crosswalk is converted, the red-to-green signal is changed to a green one, and when an unexpected situation occurs, such as a pedestrian who is waiting for a signal, rushes to the right-turning crosswalk, the driver predicts this Failure to do so may result in an accident.

1 to 6 , the pedestrian notification system 100 when the vehicle turns right according to an embodiment of the present invention includes a body unit 110 , a display unit 120 , a camera 130 , and a system controller ( 140).

The main body 110 is installed on the sidewalk before the vehicle turns right at the intersection. The main body 110 is formed in the form of a rectangular column, and the lower end thereof may be fixed to the sidewalk. In the main body 110 , one of the four corners of the outer periphery is partially flattened, so that the display unit 120 may be mounted in the depressed portion 111 .

The body unit 110 may be fixed to the sidewalk in a state where the screen of the display unit 120 is inclined toward the driver of the right-turning vehicle. Accordingly, the driver can see the screen of the display unit 120 well when turning right. As another example, the main body 110 is formed in a circular column shape, and the outer peripheral portion is partially flattened, so that the display unit 120 may be mounted in the depressed portion, so the exemplary embodiment is not limited thereto.

The display unit 120 is mounted on the body unit 110 in a state where the screen is inclined toward the driver of the right-turning vehicle. Accordingly, the screen of the display unit 120 may be easily visible to the driver's view of the right-turning vehicle. The display 120 may be configured to display notification information as text. For example, the display unit 120 may be formed of an LED signboard or the like. The display unit 120 is electrically connected to the system controller 140 . The display unit 120 is controlled by the system controller 140 .

The display unit 120 may display the presence or absence of a pedestrian in the right turn crosswalk 10 that is a crosswalk after the vehicle right turn. When the system controller 140 is linked with the local traffic signal controller 20 , the display unit 120 may display a signal change of the right turn crosswalk 10 .

For example, as shown in FIGS. 5 and 6 , the display unit 120 may display various characters such as “a person is present when turning right”, “caution for pedestrian safety”, and “a walking signal when turning right”. Accordingly, the driver of the right-turning vehicle may prevent a traffic accident by decelerating and driving with caution before turning right according to the notification information displayed through the display unit 120 .

The camera 130 is mounted on the main body 110 to always photograph the right turn crosswalk 10 . The camera 130 provides the image acquired in real time to the system controller 140 to check whether or not there is a pedestrian crossing the right-turning crosswalk 10 . The camera 130 makes it possible to check the presence or absence of a pedestrian crossing the right-turn crosswalk 10 even if there is no pedestrian traffic light on the right-turn crosswalk 10 .

In addition, when a traffic accident occurs or an accident such as disappearance or kidnapping occurs, the camera 130 can help to solve the case by the obtained image, and furthermore, it can prevent various crimes. The camera 130 may be an IP camera or a CCTV camera. An IP camera is a camera used to connect to the wired or wireless Internet.

The camera 130 may be connected to the system controller 140 by wire or wireless. The camera 130 is controlled by the system controller 140 . If there is no street light in the vicinity of the camera 130, the camera 130 may obtain a clear image by illuminating the right-turn crosswalk with infrared rays at night or in a low-illumination place. Although the camera 130 is illustrated as being mounted on the side of the main body 110 , it is also possible to be mounted on the upper end of the main body 110 .

The system controller 140 determines whether there is a pedestrian in the right-turn crosswalk 10 based on the information captured by the camera 130, and displays the presence or absence of a pedestrian in the right-turn crosswalk 10 through the display unit 120. . The system controller 140 stores the image provided from the camera 130 in the storage unit and analyzes it for each set section to determine whether or not a pedestrian is crossing the right-turning crosswalk 10, and then displays the determination result through the display unit 120. can The system controller 140 may be built in the main body 110 .

In an additional aspect, the system controller 140 may display the signal change of the right turn crosswalk 10 through the display unit 120 based on the signal information received from the local traffic signal controller 20 . Here, the system controller 140 may display a signal change of the right-turn crosswalk 10 through the display unit 120 upon receiving a yellow signal among the vehicle traffic lights of the right-turn crosswalk 10 .

In detail, in general, when a vehicle traffic light is signaled by three-color lights of red, yellow, and green, a caution and warning to reduce speed are transmitted through a yellow signal before a red stop signal. Pedestrian traffic lights are displayed with red and green bicolor lights, and there is no yellow signal. In the right turn crosswalk 10 , the pedestrian traffic light is changed to a green signal when the corresponding vehicle traffic light is changed from a yellow signal to a red signal.

Accordingly, when the display unit 120 displays the right-turn walking signal at the time when the vehicle traffic light of the right-turn crosswalk 10 is changed to a yellow signal before the red stop signal, the driver of the right-turning vehicle is in the right-turn crosswalk 10 You will know the signal change of the right turn crosswalk 10 before the waiting pedestrian.

Therefore, before the pedestrian traffic light is changed to a green signal, the driver makes a right turn with caution while decelerating with a margin for the signal change time of the vehicle traffic light according to the notification information provided through the display unit 120 . As a result, the driver can prevent a right turn accident because the driver can prepare for the pedestrian to jump out quickly when the signal is changed after only looking at the walking signal of the pedestrian traffic light.

In addition, the system controller 140 can determine the presence of a pedestrian crossing the right-turn crosswalk 10 without permission from the red walking signal and display it through the display unit 120, so that the driver can check the presence of pedestrians and signal changes when the driver turns right. Accidents can be prevented by recognizing them in advance.

As another example, the system controller 140 may receive the pedestrian traffic light signal of the right-turn crosswalk 10 from the local traffic signal controller 20 and display the walking signal through the display unit 120 .

On the other hand, the system controller 140 may be connected to the monitoring server through a wireless communication network. When the monitoring server receives a request from the outside, it can access the pedestrian notification system 100 when the vehicle turns right and monitor the area around the crosswalk 10 in real time through an image.

Specifically, the monitoring server may consist of a police control room. When the vehicle turns right, the pedestrian notification system 100 is formed to have a unique IP, and when an accident is received in the vicinity, the monitoring server connects to the pedestrian notification system 100 when the vehicle turns right and monitors the accident site in real time even from a distance By making it possible to do so, it is possible to expedite the command for handling the incident.

The monitoring server can also be built inside the police vehicle, and when a damage report is received, it connects to the pedestrian notification system 100 when a nearby vehicle turns right, and can be dispatched while checking the scene of the accident and the face of the perpetrator in real time.

In addition, the monitoring server may receive the received image, extract a face image of the pedestrian through a face recognition algorithm, and compare the extracted face image with registered face image data to recognize the pedestrian face.

Accordingly, when infants or the elderly with dementia who are difficult to own mobile devices such as smartphones go missing, the monitoring server recognizes the missing person's face based on pre-registered face data, and passes the pedestrian notification system when the vehicle turns right. By enabling a search according to the movement path and automatically requesting help, it is possible to easily find the missing person.

Although not shown, an RFID reader may be mounted on the main body 110 . The RFID reader includes a reader unit for recognizing the RFID tag information mounted on the accessory of the pedestrian to obtain the location information of the pedestrian, and a transmitter for transmitting the location information of the pedestrian to a preset mobile communication terminal through a mobile communication network.

When an RFID tag with unique identification information is mounted on an accessory of a person to be protected, such as a child or the elderly with dementia, the reader detects the RFID tag whenever the person passes by the pedestrian notification system 100 when the vehicle turns right to know the location of the protected person. Therefore, when it is transmitted to the mobile communication terminal of the guardian through the transmitter, the guardian can check the location of the protector in real time. In addition, after the maximum allowable distance is set for the RFID tag, if the RFID tag deviates from the set maximum allowable distance, the result may be transmitted to the mobile communication terminal of the guardian.

Although not shown, when the vehicle turns right, the pedestrian notification system 100 is equipped with a pedestrian traffic light and disposed on both sides of the right turn crosswalk 10 , so that it may also function as a pedestrian traffic light.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, it will be understood that this is merely exemplary, and that various modifications and equivalent other embodiments are possible therefrom by those skilled in the art. will be able Accordingly, the true scope of protection of the present invention should be defined only by the appended claims.
