[Technical field]

[0001] The present disclosure relates to an information providing system and an information providing method. [Background technology]

[0002] Conventionally, there is a technology for supporting the crackdown on traffic violations (for example, Patent Document 1). Patent Document 1 discloses a display device that identifies a traffic violation using, for example, information from the detection results of a radar for detecting speed, and displays the type of traffic violation and information on the violator identified from an image. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2016 / 113974 Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, for example, on narrow roads in residential areas, passersby may feel danger from the movement of vehicles. However, narrow roads often do not have surveillance cameras installed, and even if a traffic violation is committed, it is difficult to crack down on it. [Means for solving the problem]

[0005] The present disclosure can be realized in the following forms.

[0006] (1) According to one embodiment of the present disclosure, an information provision system is provided. The information provision system includes a receiving unit that receives danger information indicating that a passerby traveling on a road has recognized a dangerous motion of a vehicle, the danger information including location information of the dangerous motion, date and time information of the recognition of the dangerous motion, and content information of the dangerous motion, a storage unit that stores the received danger information, an identifying unit that uses the received danger information to identify a danger area in which the occurrence frequency of the dangerous motion is higher than a predetermined reference frequency, and a providing unit that provides information on the danger area. According to this embodiment, the providing unit provides information on the danger area identified using the danger information provided by the passerby, thereby encouraging the crackdown on traffic violations in the danger area. (2) In the above embodiment, the identification unit may execute a counting process for counting the number of past cases of danger information within a predetermined location range, and a determination process for determining the location range as the danger area when the counted number of cases of danger information is greater than a predetermined threshold. According to this embodiment, the identification unit can identify the danger area by executing the counting process and the determination process. In addition, since the identification unit determines a limited location range as a danger area, the area in which traffic violations are regulated can be narrowed down to the limited location range by appropriately setting the location range. (3) In the above embodiment, the position range may be a range surrounded by a circle having a predetermined radius. According to this embodiment, for example, a range including an intersection where a dangerous action is likely to be performed can be specified as a dangerous area. (4) In the above embodiment, the center of the circle may be a position indicated by the position information of the latest danger information received by the receiving unit. According to this embodiment, the identifying unit can identify a danger area by using the latest danger information. Therefore, for example, when the number of danger information cases increases suddenly, it is possible to increase the possibility of providing the user with information on the danger area soon after the sudden increase. (5) In the above embodiment, the location range is a range of the road having a predetermined route length, and at least one of a traffic signal and a pedestrian crossing may not be installed on the road in the location range. According to this embodiment, for example, a road that is likely to become a shortcut can be identified as a dangerous area. (6) In the above embodiment, the identification unit may, in the counting process, count the number of the past danger information for each predetermined time period, and, in the identification process, identify the danger area for each time period using a threshold value that is set individually for each time period. According to this embodiment, the time period during which traffic violations are regulated can be narrowed down to a limited time period. (7) In the above embodiment, the information on the danger area may be map information showing the range of the danger area. According to this embodiment, the user can check the danger area on a map. This can improve the convenience of the information providing system. (8) In the above embodiment, the receiving unit may further receive terminal location information provided from an information terminal device, the terminal location information indicating a current location of the information terminal device, and the providing unit may transmit an alarm to the information terminal device in a first case where the current location is located within the danger area and in a second case where the current location is located outside the danger area and the distance between the current location and the danger area is shorter than a predetermined reference distance. According to this embodiment, a user of the information terminal device can recognize or avoid a danger area without having to check the danger area against the current location by himself / herself. In addition to the information provision system described above, the present disclosure can be realized in the form of an information provision method or program, a non-transitory tangible recording medium on which the program is recorded so as to be readable by a computer, and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] A. Embodiment: 1 is an explanatory diagram showing a schematic configuration of an information providing system 10. The information providing system 10 includes an information terminal device 100 used by passersby, and a server 200. The information providing system 10 is a system that uses danger information provided by passersby via the information terminal device 100 to provide dangerous area information 224, which is information on dangerous areas identified by the server 200. The information providing method is realized by performing a reception step performed by the reception unit 112, a dangerous area identification process, and a provision step performed by the provision unit 212, which will be described later.

[0009] The server 200 is configured as a computer including a CPU 210, a communication unit 202, and a storage unit 220. The communication unit 202 includes a circuit for communicating with the information terminal device 100 via the Internet 80. The CPU 210 controls the overall operation of the server 200 by executing a program stored in the storage unit 220. The CPU 210 includes an identification unit 211 and a provision unit 212. The identification unit 211 and the provision unit 212 are functional units that are realized by the CPU 210 executing a program stored in the storage unit 220. The identification unit 211 identifies a dangerous area where the occurrence frequency of dangerous actions is higher than a predetermined reference frequency. The provision unit 212 performs a provision step of providing information on the dangerous area. In addition to the program executed by the CPU 210, the storage unit 220 stores map information 222, a danger information database 223, and dangerous area information 224. The map information 222 stores road network data that indicates the connection state of roads using link data that indicates roads and node data that indicates intersections, bends, and dead ends.

[0010] The information terminal device 100 can access a server 200 connected to the Internet 80 via a communication carrier 70 or a wireless LAN. The information terminal device 100 is configured as a computer including a CPU 110, a storage unit 120, a positioning unit 114, a touch panel 126, and a communication unit 128. The information terminal device 100 is, for example, a mobile terminal such as a smartphone, a tablet terminal, or a notebook computer.

[0011] The positioning unit 114 includes a GNSS (Global Navigation Satellite System) receiver, and measures the latitude and longitude of the current position of the information terminal device 100 based on radio waves received from artificial satellites that make up the GNSS.

[0012] The touch panel 126 has a display function for displaying information and a reception function for receiving operations. The information terminal device 100 may also include other input devices such as various buttons, a joystick, and a touch pad.

[0013] The communication unit 128 includes a circuit for performing data communication with the server 200 via the communication carrier 70, wireless LAN communication, or the like.

[0014] The CPU 110 controls all the components of the information terminal device 100. A danger information application program (hereinafter, referred to as danger information application 121) is stored in the storage unit 120. The CPU 110 executes the danger information application 121 stored in the storage unit 120 to realize functional units such as a reception unit 112. These functional units may be realized by hardware such as a circuit.

[0015] The memory unit 120 stores map information 122. The CPU 110 acquires map information of the surrounding area of ​​the current position measured by the positioning unit 114 from the server 200 and stores the map information in the memory unit 220 when requested by the danger information application 121 or the like.

[0016] The reception unit 112 performs a reception process of receiving danger information indicating that a pedestrian traveling on a road has recognized a dangerous motion of a vehicle. The danger information includes position information indicating the position where the dangerous motion was performed, date and time information indicating the date and time when the dangerous motion was recognized, and content information indicating the content of the dangerous motion. As will be described later, the reception unit 112 displays an operation screen on the touch panel 126 to receive operations.

[0017] FIG. 2 is a diagram showing a main screen that is initially displayed when the danger information application 121 is launched. On the main screen, a first selection button WG11 for receiving input of danger information and a second selection button WG12 for receiving an instruction to provide danger area information 224 are displayed. When a passerby wants to input danger information, he or she taps the first selection button WG11 to select it. In the following description, "tapping to select" is simply referred to as "selecting". The second selection button WG12 is a selection button that is selected when a passerby wants to be provided with danger area information 224.

[0018] When the first selection button WG11 is selected, the reception unit 112 displays an input reception screen. Fig. 3 is a diagram showing the input reception screen. As shown in Fig. 3, the input reception screen displays a first input area WG21, a second input area WG22, a third input area WG23, a fourth input area WG24, an information input selection button WG25, and a send button WG26.

[0019] The first input area WG21 is an area for receiving position information in which a dangerous motion is recognized. In the first input area WG21, selection buttons for receiving either "current location" or "input from map" are displayed. If the place where the dangerous motion was recognized is the current location, the passerby selects "current location." If the place where the dangerous motion was recognized is not the current location, the passerby selects "input from map." If "input from map" is selected, the reception unit 112 displays a map in the vicinity of the current location, and receives the tapped location on the map as the position information in which the dangerous motion was recognized.

[0020] The second input area WG22 is an area for receiving date and time information when the dangerous motion was recognized. The second input area WG22 displays selection buttons for receiving input of either "current time" or "select and input." If the date and time when the dangerous motion was recognized is approximately the current time, the passerby selects "current time." If the date and time when the dangerous motion was recognized is not the current time, the passerby selects "select and input." If "select and input" is selected, the reception unit 112 displays a date and time reception screen (not shown) for receiving the date and time, and accepts the date and time input on the date and time reception screen as date and time information when the dangerous motion was recognized.

[0021] The third input area WG23 is an area for receiving the details of the dangerous action. Selection buttons for receiving any one of "No temporary stop", "Excess speed", and "Other" are displayed in the third input area WG23. When the "Other" selection button is selected, the reception unit 112 displays a character input screen (not shown) for receiving character input, and receives the character information input to the character input screen as the details of the dangerous action.

[0022] "Failure to stop" refers to a dangerous behavior in which a vehicle does not stop at a place designated by law or where there is a stop sign, or a dangerous behavior in which a passerby feels that a vehicle is suddenly coming out. "Speeding" refers to a dangerous behavior in which a vehicle is traveling at a speed that exceeds the legal upper limit, or a speed that a passerby feels is dangerous. "Other" dangerous behaviors include, for example, the dangerous behavior of driving a vehicle while looking at a smartphone or swerving on a bicycle.

[0023] The fourth input area WG24 is an area for receiving the type of vehicle that performed the dangerous action. Selection buttons for receiving input of any one of "Automobile", "Two-wheeled vehicle", "Motorcycle", "Bicycle", and "Other" are input into the fourth input area WG24. When the "Other" selection button is selected, a character input screen for receiving character input (not shown) is displayed, and character information input into the character input screen is accepted as information on the type of vehicle.

[0024] When the information input selection button WG25 is selected, a character input screen (not shown) for accepting character input is displayed, and character information entered on the character input screen is accepted as other information. Other information refers to, for example, information identifying the vehicle, such as the model and color of the vehicle, and information identifying the person in the vehicle.

[0025] When the passerby has finished inputting all items, he / she selects the send button WG 26. When the send button WG 26 is selected, the reception unit 112 transmits the information, including the information on each area, received on the input reception screen to the server 200 as danger information.

[0026] When the server 200 receives the danger information, it executes a dangerous area identification process. Fig. 4 is a flowchart showing the procedure of the dangerous area identification process.

[0027] In step S10 as a storage step shown in FIG. 4, the identification unit 211 adds the received danger information to the danger information database 223 to update the danger information database 223. Hereinafter, the received danger information is also referred to as "latest danger information". FIG. 5 is a diagram for explaining the danger information database 223. As shown in FIG. 5, the danger information database 223 is a database in which the items "location", "date and time", "content", "vehicle", and "other" are grouped together. The value of "location" in the danger information database 223 is input with information input in the first input area WG21 of the input reception screen. The value of "date and time" in the danger information database 223 is input with information input in the second input area WG22 of the input reception screen. The value of "content" in the danger information database 223 is input with information input in the third input area WG23 of the input reception screen. The value of "vehicle" in the danger information database 223 is input with information input in the fourth input area WG24 of the input reception screen. The information input to the information input selection button WG25 on the input reception screen is input as the "other" value in the danger information database 223. One row in the danger information database 223 corresponds to one piece of danger information.

[0028] By performing the processing steps from step S12 to step S16 shown in Fig. 4, the identification unit 211 identifies a risk area where the occurrence frequency of risky actions is higher than a predetermined reference frequency. In this embodiment, the identification unit 211 obtains, as the occurrence frequency, the number N of risk information cases in the past three months in a location range including the location indicated by the latest risk information, and if the obtained number is greater than a threshold value Nth, identifies this location range as a risk area. This will be described in detail below.

[0029] In step S12 as the counting process, the identification unit 211 refers to the danger information database 223 and counts the number N of danger information cases for the past three months in a location range including the latest location indicated by the location information included in the received danger information. In this embodiment, the location range is a range surrounded by a circle of a predetermined radius centered on the latest location. In this embodiment, the predetermined radius is 10 m. Note that the period to be counted is not limited to three months, and may be a period shorter or longer than three months.

[0030] In step S14, the identification unit 211 determines whether the number N is greater than a predetermined threshold Nth. In this embodiment, the threshold Nth is "10." If it is determined in step S14 that the number N is not greater than the predetermined threshold Nth, the identification unit 211 ends this processing routine. If it is determined in step S14 that the number N is greater than the predetermined threshold Nth, the identification unit 211 identifies the location range as a dangerous area in step S16 as an identification process and identification step.

[0031] In step S18, the identification unit 211 adds the dangerous area identified in step S16 to the dangerous area information 224 to update it, and ends this processing routine.

[0032] Fig. 6 is a diagram for explaining the dangerous area information 224. As shown in Fig. 6, the dangerous area information 224 is map information indicating the range of the dangerous area.

[0033] As described above, in this embodiment, the danger area information 224 is a circular area defined by a center position and a radius. At least 10 pieces of danger information are associated with the danger area. The danger area information 224 is provided by the providing unit 212 as electronic data to an information processing device connected to the Internet 80, for example, via the Internet 80. Note that the danger area information 224 is not limited to electronic data, and may be provided as a printed matter in which the danger area information 224 is printed. The danger area information 224 is provided, for example, to a police station that cracks down on traffic violations. This can encourage the police to crack down on traffic violations in the danger area.

[0034] The dangerous area information 224 may not be provided to police stations. The dangerous area information 224 may be provided to drivers of automobiles or, as described below, to passersby. Automobiles are required to stop at crosswalks where pedestrians are present. Therefore, by using the provided dangerous area information 224, drivers of automobiles can check dangerous areas where the content of the dangerous action is "not stopping temporarily" and where there is a crosswalk within the area, and can be careful not to not stop temporarily at the relevant crosswalk.

[0035] Moreover, the providing unit 212 of the server 200 provides the created danger area information 224 to the information terminal device 100. Specifically, when the second selection button WG12 displayed on the main screen shown in FIG. 2 is selected, the danger area information 224 is provided. The provided danger area information 224 may be information about the vicinity of the current location of the information terminal device 100, or may be partial danger area information 224 of an area registered in advance in a danger information application. When the danger area information 224 is provided, the information terminal device 100 displays map information showing the range of the danger area on the touch panel 126 as shown in FIG. 6. When the danger area information 224 is displayed on the touch panel 126, the danger area is displayed in red, for example. When the danger area is enlarged and displayed on the touch panel 126, details of each piece of danger information associated with the danger area information 224 are displayed. The details of the danger information are, specifically, the date and time included in the danger information, the contents of the dangerous action, and the like. By providing the danger area information 224, a passerby can recognize the danger area and can avoid the danger area. Providing the dangerous area information 224 to passersby is particularly beneficial when the passersby are vulnerable road users, such as elderly people or children.

[0036] According to the embodiment described above, the information provision system 10 includes a receiving unit 112 that receives danger information, a storage unit 120 that stores the danger information, an identifying unit 211 that identifies a danger area, and a providing unit 212 that provides danger area information 224 that is information on the danger area. The identifying unit 211 identifies a danger area where the occurrence frequency of a dangerous action is higher than a reference frequency. The provision of the danger area information 224 can encourage the crackdown on traffic violations.

[0037] Furthermore, in step S12 of the risk area identification process, the identification unit 211 tallies the number N of risk information cases in the past three months in a predetermined location range. If the number N is greater than a predetermined threshold Nth, in step S16, the identification unit 211 identifies the location range as a risk area. As a result, the identification unit 211 identifies a limited location range as a risk area, and therefore the area in which traffic violations are regulated can be narrowed down to the limited location range.

[0038] Moreover, the location range is a range surrounded by a circle with a predetermined radius. Therefore, a range including an intersection where a dangerous action is likely to be performed can be specified as a dangerous area. Furthermore, in step S12 of the dangerous area specification process, the specification unit 211 counts the number N of dangerous information for the past three months in a location range surrounded by a circle centered on the latest location. Then, if the number N is greater than a predetermined threshold value Nth, in step S16, the specification unit 211 specifies the location range as a dangerous area. This allows the specification unit 211 to specify a dangerous area using the latest dangerous information, so that when the number of dangerous information items increases suddenly, it is possible to increase the possibility of providing the user with information on the dangerous area without any time lapse from the time when the number of dangerous information items increases suddenly.

[0039] Moreover, the danger area information 224 is map information showing the range of the danger area. Therefore, a user to whom the danger area information 224 is provided can check the danger area on the map, and the convenience of the information providing system 10 can be improved.

[0040] B. Other embodiments: (B1) In the above embodiment, the number N of dangerous information in the past three months is calculated as the occurrence frequency of the dangerous action. The occurrence frequency of the dangerous action is not limited to the number of dangerous information in a predetermined period. For example, the time interval at which the dangerous information is transmitted may be calculated as the occurrence frequency, and if the time interval is shorter than a reference interval, the location range may be identified as a dangerous area.

[0041] (B2) In the above embodiment, when the information terminal device 100 provides danger information, the identification unit 211 executes the danger area identification process. The time when the danger area identification process is executed is not limited to this. The identification unit 211 may execute the danger area identification process periodically, for example, once a week. By adjusting the time when the danger area identification process is executed, for example, for each region, so that it does not overlap, it is possible to avoid an increase in calculation load caused by the concentration of the execution time of the danger area identification process when a large amount of danger information is provided in a short period of time. In addition, when the identification unit 211 executes the danger area identification process periodically, the number N obtained in step S12 may be stored and accumulated in the storage unit 120 in association with the date and time when the danger area identification process was executed. This makes it possible to create information on the transition of the number N of danger information. In this case, instead of a method of tallying up the number of past danger information in a predetermined position range, an area where danger information is concentrated may be identified as a danger area.

[0042] (B3) In the above embodiment, the location range in step S12 is a range of a circle with a predetermined radius centered on the latest position. As another form of the location range in step S12, it may be a range of a circle with a predetermined radius centered on a preset position. For example, by setting the center position at an intersection, it is possible to identify an intersection where a dangerous action is likely to be performed as a dangerous area. Also, as another form of the location range in step S12, it may be a range of a road in a section where at least one of a traffic signal and a pedestrian crossing is not installed, and the road may have a predetermined route length. FIG. 7 is a diagram for explaining another embodiment of the location range. As shown in FIG. 7, the location range AR indicated by the dashed line is a range where neither a traffic signal nor a pedestrian crossing is installed, and the route length PL is a predetermined length. The route length PL is, for example, 500 m. Roads without traffic signals or pedestrian crossings may be shortcuts to main roads, and by setting such roads as the location range, it is possible to identify roads that are likely to be shortcuts as dangerous areas. Furthermore, as the location range, in addition to traffic signals and pedestrian crossings, roads where no surveillance cameras are installed may be set.

[0043] (B4) In the above embodiment, in step S12, the number N of cases in the past three months is counted with the latest danger information as the base point. In step S12, the number of past danger information cases that include the time indicated by the date and time information in the same time zone as the time zone including the time indicated by the date and time information of the latest danger information may be counted. Then, in step S14, a threshold value set individually for each time zone may be used as the threshold value Nth. Specifically, a day is divided into, for example, four time zones, morning, afternoon, night, and night, and when the time indicated by the date and time information of the latest information is 9 o'clock included in the "morning time zone", the identification unit 211 counts the danger information included in the "morning time zone" that has the same time zone. Then, in step S14, the identification unit 211 compares the number N with the threshold value Nth set individually for the "morning time zone". Specifically, the morning, afternoon, night, and night are, for example, 5:00 to 11:00, 11:00 to 17:00, 17:00 to 23:00, and 23:00 to 5:00, respectively. According to this embodiment, the time for cracking down on traffic violations can be narrowed down to a limited time period. In addition, by setting the threshold value Nth for each time period individually, the threshold value Nth can be adjusted for each time period. For example, since it is expected that the number of dangerous information items is smaller in the "midnight time period" than in the "morning time period", the threshold value Nth for the "midnight time period" can be set in advance to be smaller than the threshold value Nth for the "morning time period". In addition, when it is desired to strengthen the crackdown on the "morning time period", which is the time period for commuting to work or school, the threshold value Nth for the "morning time period" can be set to be smaller. When the dangerous area identification process is periodically executed as in (B2) above, the identification unit 211 may, in the counting process, count the number N of past dangerous information items for each predetermined time period, and in the identification process, identify the dangerous area for each time period using the threshold value Nth that is individually set for each time period as the threshold value Nth. The dangerous area information 224 may be information for each time period. Moreover, when the second selection button WG12 (FIG. 2) is selected, the providing unit 212 may provide the danger area information 224 for the time period corresponding to the time when the second selection button WG12 (FIG. 2) is selected. For example, during the nighttime hours when visibility is poor, it is difficult for passersby to avoid dangerous vehicle movements.Therefore, at night, the provision of the night-time dangerous area information 224 is more beneficial since it allows passersby to avoid dangerous areas.

[0044] (B5) In the above embodiment, the information on the danger area is provided as map information. As a form of providing the information on the danger area, an alarm for calling attention may be provided to the information terminal device 100 when the current position of the information terminal device 100 is in the danger area or close to the danger area. Specifically, the receiving unit 112 further receives terminal position information indicating the current position of the information terminal device 100, which is position information provided from the information terminal device 100. The providing unit 212 transmits an alarm to the information terminal device 100 in a first case where the current position is located in the danger area, and in a second case where the current position is located outside the danger area and the distance between the current position and the danger area is shorter than a predetermined reference distance. The distance between the current position and the danger area is the shortest distance between the outer periphery of the danger area and the current position. The reference distance is, for example, 5 m. According to this form, the user of the information terminal device 100 can recognize or avoid the danger area without checking the danger area against the current position by himself. Furthermore, in the case where risk areas are identified for each time period as in (B4) above, the receiving unit 112 may compare the current location with the risk areas for the time period corresponding to the time at which the terminal location information is received from the information terminal device 100, and transmit an alarm in the first case or the second case above.

[0045] (B6) In the above embodiment, the dangerous areas are displayed on a map and provided as the dangerous area information 224. In another embodiment, the location of the dangerous area may be provided as text information such as an address. Furthermore, the providing unit 212 may create map information as the dangerous area information 224, organized by administrative region such as a city or town, or by school district such as an elementary school, and provide the map information to the government.

[0046] (B7) The server 200 may further include a route guidance unit that performs navigation to the destination, and the route guidance unit may create route information that avoids dangerous areas and provide it to the information terminal device 100. Specifically, the route guidance unit receives the current position and the location information of the destination from the information terminal device 100, and searches for a route from the current position to the destination, that is, a recommended route that avoids dangerous areas, using map information that excludes dangerous areas from the map information 222. Then, the recommended route is provided to the information terminal device 100. According to this embodiment, the user of the information terminal device 100 can reach the destination while avoiding dangerous areas. Also, in the case where dangerous areas are specified for each time period as in (B4) above, the route guidance unit may search for a recommended route that avoids dangerous areas using dangerous areas corresponding to the time when the current position and the location information of the destination are received from the information terminal device 100.

[0047] The present disclosure is not limited to the above-mentioned embodiment, and can be realized in various configurations without departing from the spirit of the present disclosure.
