Summary of the Invention

Problems to be Solved by the Invention

[0006] A common problem with typical school zones is that only pre-defined areas are subject to speed limits and traffic direction restrictions, making it impossible to impose regulations on other areas. This is also the case in Patent Document 1, where only areas meeting certain conditions, such as being within a specified range from the school facility's main gate, densely populated residential areas, or general roads or narrow streets, are designated as school zones. Furthermore, there is another problem: warnings targeting unnecessarily large areas reduce the effectiveness of the warning.

[0007] In addition to pedestrians, there is also a need to monitor all types of mobile devices, such as bicycles and delivery robots, to ensure their safe movement.

[0008] The present invention aims to provide a warning area setting device, a warning area notification system, a notification warning area setting method, and a recording medium that can more effectively contribute to improving the safety of moving objects. [Means for solving the problem]

Embodiments for Carrying Out the Invention

[0015] First, an overview of an embodiment of the present invention will be described with reference to the drawings. Note that the reference numerals in the drawings attached to this overview are for convenience and are attached to each element as an example to assist understanding, and are not intended to limit the present invention to the illustrated embodiments. Also, the connection lines between the blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional ones. The one-way arrow schematically shows the flow of the main signal (data) and does not exclude bidirectionality. The program is executed via a computer device, and the computer device includes, for example, a processor, a storage device, an input device, a communication interface, and a display device as required. Also, this computer device is configured to be able to communicate with devices inside or outside the device (including computers) via a communication interface, whether wired or wireless. Also, ports or interfaces are provided at the input / output connection points of each block in the figure, but the illustration is omitted.

[0016] In one embodiment of the present invention, as shown in FIG. 1, it can be realized by a warning area notification system 10 including a detection means 11, an area setting means 12, and a notification means 13.

[0017] More specifically, the detection means 11 detects a moving object located in a predetermined monitoring area. As the moving object, a pedestrian, a bicycle, an unmanned transport vehicle, a specific vehicle, etc. can be considered.

[0018] The area setting means 12 determines the range of the warning area based on the arrangement of the mobile body within the monitoring area.

[0019] The notification means 13 transmits a notification to a vehicle entering the warning area to inform it of the presence of the warning area.

[0020] Figure 2 shows a map of a school and its surrounding area in a certain region. The circle with a radius of 500m in the figure indicates the area used to define the school zone. Area MA, shown by a dashed line, indicates the monitoring area where the detection means 11 detects moving objects.

[0021] Figure 3 shows an example of a warning area set by the area setting means 12. The five face marks, represented by the symbol P in the figure, represent pedestrians. In the example in Figure 3, the area setting means 12 determines a warning area that covers the location of a moving object, as shown in Figure 3. The notification means 13 sends a notification to vehicles entering such a warning area to inform them of the presence of the warning area. This notification may also include information such as the presence of pedestrians and speed limits, in addition to the presence of the warning area.

[0022] Furthermore, the aforementioned warning area is updated in accordance with changes in the arrangement of moving objects. For example, if, after a predetermined time has elapsed from the state shown in Figure 3, the arrangement of moving objects as shown in Figure 4 is obtained, the area setting means 12 expands the warning area according to the arrangement of moving objects. By changing the shape (range) of the warning area in accordance with changes in the arrangement of moving objects in this way, it becomes possible to appropriately warn vehicles entering the warning area.

[0023] Of course, the warning area may be reduced in size or deleted. For example, if the arrangement of the moving object as shown in Figure 3 is obtained after a predetermined time has elapsed from the state shown in Figure 4, the area setting means 12 may return the warning area to its original size. Also, as shown in Figure 2, if there is no moving object, the area setting means 12 may delete the warning area.

[0024] As described above, by setting a warning area based on the position of the moving object and providing necessary warnings, the safe movement of the moving object can be achieved. The warning area notification system 10 shown in Figure 1 can also be composed of two devices: a warning area setting device equipped with a detection means 11 and an area setting means 12, and a notification device equipped with a notification means 13.

[0025] [First Embodiment] Next, a first embodiment of the present invention will be described in detail with reference to the drawings. Figure 5 is a diagram showing the configuration of the warning area notification system of the first embodiment of the present invention. Referring to Figure 5, the configuration includes a plurality of cameras 500, a warning area notification system 100, and a vehicle 300 to which notifications based on the warning area will be sent.

[0026] Camera 500 is installed at various locations within the monitoring area that is monitored by the warning area notification system 100, and provides the warning area notification system 100 with the images it has captured. Various types of security cameras and traffic flow monitoring cameras installed near intersections and roads can be used as cameras 500. Alternatively, a multi-functional terminal with a camera, known as a smart pole, can also be used as camera 500.

[0027] The warning area notification system 100 includes a detection means 101, an area setting means 102, a notification means 103, a warning area information storage means 104, a vehicle detection means 105, a map information storage means 106, and a warning area setting rule storage means 107.

[0028] The detection means 101 detects pedestrians as moving objects located in the monitoring area based on images acquired from the camera 500 and identifies their positions. The position of a pedestrian can be determined based on the installation location of the camera 500 and the position and size of the pedestrian in the image. In this embodiment, pedestrians are detected from the camera 500, but for example, if the warning area notification system 100 can obtain location information from a mobile terminal carried by a pedestrian, that information may be used to detect the pedestrian and their position. For example, a method in which a roadside unit communicates with a mobile terminal via short-range wireless communication to detect moving objects and their attributes can also be employed.

[0029] The map information storage means 106 stores map information including the monitoring area that is monitored by the warning area notification system 100.

[0030] The warning area setting rule storage means 107 stores rules for setting warning areas based on the pedestrian placement detected by the detection means 101. One example of such a rule is setting warning areas based on the presence and density of pedestrians within the grid (section) set up within the aforementioned monitoring area. A specific method for setting warning areas will be explained later along with the operation of the warning area notification system 100.

[0031] The area setting means 102 sets a warning area on the map read from the map information storage means 106, based on the pedestrian placement detected by the detection means 101 using the rules. The area setting means 102 stores the set warning area in the warning area information storage means 104.

[0032] The warning area information storage means 104 provides the vehicle detection means 105 with information about the warning area.

[0033] The vehicle detection means 105 detects a vehicle that has entered a warning area based on the image acquired from the camera 500 and the warning area information acquired from the warning area information storage means 104. The vehicle detection means 105 requests the notification means 103 to send a notification to the vehicle that has entered the warning area to inform it of the presence of the warning area.

[0034] Based on a request from the vehicle detection means 105, the notification means 103 transmits a notification to vehicles entering the warning area via roadside units or base stations installed around roads and at intersections, informing them of the presence of the warning area. The notification means 103 can selectively transmit notifications to vehicles entering the warning area by broadcasting a notification containing information identifying the target vehicle, allowing the vehicle to recognize that the notification is for it. Alternatively, the notification means 103 can transmit a notification directly to a vehicle entering the warning area via unicast. In this case, the vehicle detection means 105 reads identification information such as the vehicle's license plate number and uses that identification information to obtain the vehicle's communication address from an external server.

[0035] Next, the operation of this embodiment will be described in detail with reference to the drawings. Figure 6 is a flowchart showing the operation (updating of the warning area) of the warning area notification system 100 of the first embodiment of the present invention. Referring to Figure 6, first the warning area notification system 100 acquires image data from the camera 500 (step S001).

[0036] Next, the warning area notification system 100 detects pedestrians and other persons, identifies their location, and understands their distribution (placement) (step S002).

[0037] The warning area notification system 100 updates the warning area based on the distribution (placement) of pedestrians (step S003).

[0038] Figure 7 illustrates an example of how the Warning Area Notification System 100 sets up a warning area. The monitoring area MA in Figure 7 is divided into three 3x3 grids (sections). For example, if a rule is established that a grid (section) should be set as a warning area if there are m or more pedestrians (m≧1) in that grid (section), the Warning Area Notification System 100 will select the grids (sections) labeled Z1 and Z2 in Figure 7, where pedestrians P1 to P5 are located, and set them as warning areas. In this way, the warning area can be set by selecting an area where the density of moving objects is above a predetermined value. The threshold value m can be changed as appropriate depending on the type of moving object, the purpose of the warning, etc.

[0039] Furthermore, the warning area can also be defined by excluding areas where the density of moving objects is below a predetermined value. For example, if there are n or fewer pedestrians per grid (section) (n≧0), the warning area can be defined by excluding that grid (section) from the warning area. In the example in Figure 7, the warning area can be defined by excluding grids (sections) Z3 to Z9 from the entire monitoring area MA where pedestrians P1 to P5 do not exist. The threshold value n can be changed as appropriate depending on the type of moving object, the purpose of the warning, etc., and for example, a value of 1 or greater can be set.

[0040] The warning area notification system 100 performs the above-described warning area update process at predetermined intervals and updates the warning area according to the distribution (placement) of pedestrians. Note that the grid (sections) shown in Figure 7 is merely an example, and it is possible to set a finer grid (section) depending on the position detection accuracy of the detection means 101, etc.

[0041] Figure 8 is a flowchart illustrating the operation (notification based on a warning area) of the warning area notification system 100 according to the first embodiment of the present invention. Referring to Figure 8, first the warning area notification system 100 acquires image data from the camera 500 (step S101).

[0042] Next, the warning area notification system 100 detects vehicles that have entered the warning area, identifies their location, and understands their distribution (placement) (step S102).

[0043] Next, the warning area notification system 100 sends a notification to a vehicle that has entered the warning area to inform it of the presence of the warning area (step S103). This notification may include information such as the speed limit and the presence of pedestrians that apply in the warning area, in addition to informing the vehicle that it has entered the warning area.

[0044] As explained above, according to this embodiment, it is possible to dynamically set a warning area according to the distribution (arrangement) of pedestrians and to warn vehicles entering that warning area. Furthermore, in the embodiment described above, an example was given in which a warning area is set around a school as shown in Figure 7, but this warning area can be operated as an area equivalent to a school zone. In this case, compared to the fixed school zone described in the background art, this embodiment allows roads without pedestrians (children) to be excluded from the warning area, regardless of whether they are included in the conventional school zone or not. Moreover, this embodiment has the remarkable effect of allowing roads with pedestrians (children) to be included in the warning area, regardless of whether they are included in the conventional school zone or not.

[0045] [Second Embodiment] Next, a second embodiment in which the above-mentioned warning area notification system 100 sets a warning area for each type of moving object will be described in detail with reference to the drawings. Figure 9 is a diagram showing the configuration of the warning area notification system of the second embodiment of the present invention. The differences from the first embodiment shown in Figure 5 are the detection means 111, the area setting means 112, and the warning area setting rule storage means 117. The other configurations are the same as in the first embodiment, so the following will focus on explaining the differences.

[0046] The detection means 111 of this embodiment is capable of identifying the attributes or type of a moving object, in addition to its presence.

[0047] Furthermore, the warning area setting rule storage means 117 of this embodiment stores warning area setting rules set for each attribute or type of moving object.

[0048] Furthermore, the area setting means 112 of this embodiment sets different warning areas based on the attributes or types of moving objects identified by the detection means 111, by referring to the rules stored in the warning area setting rule storage means 117.

[0049] Figure 10 shows an example of a warning area set by the warning area notification system 100a of the second embodiment. In the example in Figure 10, the warning area notification system 100a detects bicycle B as a moving object and sets a warning area WA using rules for bicycles. By setting such a warning area WA, it is possible to set a warning area that takes bicycles into consideration during morning and evening commuting hours.

[0050] Figure 11 shows another example of a warning area set by the warning area notification system 100a of the second embodiment. In the example in Figure 11, the warning area notification system 100a detects the delivery robot AVG as a mobile entity and sets a warning area WA using rules for the delivery robot. By setting such a warning area WA, it is possible to set a warning area that takes into consideration the delivery robot AVG, which travels at low speeds on sidewalks and other areas to make deliveries.

[0051] Figure 12 shows another example of a warning area set by the warning area notification system 100a of the second embodiment. In the example in Figure 12, the warning area notification system 100a detects a platoon of vehicles V1 as a moving object and sets a warning area WA using rules for the platoon of vehicles V1. In the example in Figure 12, the warning area notification system 100a sets a warning area that extends in the direction of travel of the platoon of vehicles V1. This makes it possible to provide early warnings to vehicles approaching from the road in the direction of travel of the platoon of vehicles V1.

[0052] As described above, according to this embodiment, it is possible to set up warning areas according to the type and attributes of the moving object and to warn approaching vehicles.

[0053] [Third Embodiment] Next, a third embodiment in which the warning area setting function and the notification function of the above-mentioned warning area notification system 100 are distributed to separate devices will be described in detail with reference to the drawings. Figure 13 is a diagram showing the configuration of the warning area notification system of the third embodiment of the present invention. The difference from the first embodiment shown in Figure 5 is that the warning area notification system 100 is composed of two devices: a warning area setting device 110 and a notification device 120. The functional elements of each device are the same as in the first embodiment, so their explanation will be omitted.

[0054] According to this embodiment, multiple notification devices 120 can be deployed to a single warning area setting device 110. The notification devices 120 are distributed within the monitoring area, and each detects the entry of a vehicle into the area assigned to it and issues a notification. Therefore, even when there are many target vehicles, it is possible to prevent delays in notifications based on the warning area.

[0055] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and further modifications, substitutions, and adjustments can be made without departing from the basic technical concept of the present invention. For example, the network configuration, the configuration of each element, and the data representation form shown in each drawing are examples to aid in understanding the present invention, and the present invention is not limited to the configurations shown in these drawings.

[0056] For example, in the first to third embodiments described above, examples were given of pedestrians, bicycles, delivery robots, and platooning vehicles as the target of the moving objects, but other moving objects can also be targeted for detection by the warning area notification system. Also, in the embodiments described above, pedestrians were uniformly targeted for detection, but for example, the warning area may be set up to target vulnerable road users such as children and the elderly.

[0057] In the embodiment described above, all vehicles entering the warning area were uniformly subject to notification. However, it is also possible to configure the system to select and notify specific vehicle types or vehicles with specific characteristics. For example, by making vehicles with beginner driver or elderly driver marks the target of notification, it becomes possible to provide warnings specifically to these vehicles. Furthermore, by making vehicles exceeding a certain speed or vehicles exhibiting dangerous signs such as swerving the target of notification, it becomes possible to provide warnings specifically to these vehicles.

[0058] (Regarding hardware configuration) In each embodiment of this disclosure, each component of each device represents a functional unit block. Some or all of each component of each device is realized by any combination of an information processing device 900 and a program, for example, as shown in Figure 14.

This program 904 can also be recorded on a computer-readable (non-transitive) recording medium.

[0061] There are various variations in how each device is implemented. For example, each device may be implemented by any combination of a separate information processing device 900 and a program for each component. Alternatively, multiple components of each device may be implemented by any combination of a single information processing device 900 and a program. That is, each part (processing means, function) of the warning area notification system shown in the first to third embodiments described above can be implemented by a computer program that causes a processor mounted on the device to execute the above-described processing using its hardware.
