The navigation system according to the present embodiment includes a function as an automatic speed violation control information providing device that provides information regarding an automatic speed violation control device (orvis device) that affects a running vehicle.

  FIG. 1 is a diagram showing an overall configuration of a navigation system according to the present embodiment. As shown in the figure, the system includes a user terminal device 1 that can be carried by a user of the system and a server 3 that can communicate with the user terminal device 1.

  The user terminal device 1 may be a terminal device including a portable computer having a communication function, and may be, for example, a mobile phone, a portable information terminal, or a portable personal computer. The server 3 may be configured by a general-purpose computer system, for example. The user terminal device 1 and the server 3 can communicate via wired and wireless networks (not shown). The individual components or functions in the user terminal device 1 and the server 3 described below are realized by executing a computer program, for example.

  The user terminal device 1 includes an input device 101 such as a push button, a pointing device, or a touch panel, a display device 102 such as a liquid crystal display or an organic EL display, and an otowo speaker 103 as a user interface. Further, the user terminal device 1 includes, as internal functions, a route search engine 11, an orbis selection unit 13, an alarm target orbis data storage unit 15, a display control unit 16, a sound output control unit 17, and an alarm determination unit. 18 and a GPS processing unit 19.

  The display device 102 and the speaker 103 are output means for outputting automatic speed violation control information based on the installation position of the orvis device stored in the alarm target orvis data storage unit 15.

  The server 3 includes an orvis data storage unit 31, a map image data storage unit 33, a search area setting unit 35, and an orbis extraction unit 37 as internal functions.

  The orbis data storage unit 31 stores orbis data relating to installation conditions of each orvis device. In the present embodiment, the orbit data generated by the external system is captured and stored in the orvis data storage unit 31. The Orbis data includes, for example, an installation position where each of a plurality of Orbis devices is installed, and an installation direction indicating a traveling direction of a road to be controlled. Furthermore, the orbis data may include the road type of the road that each orvis is subject to control.

  FIG. 2 shows an example of the Orvis data 310. As shown in the figure, the Orbis data 310 includes an Orbis ID 311, an installation position 313, a road type 315, and a control lane direction 317 as data items. The Orbis ID 311 is identification information of each Orbis device. The installation position 313 indicates the position where the Orbis device is installed in latitude and longitude. The road type 315 indicates the type of road that the Orvis device is subject to crackdown. The road type 315 indicates, for example, whether it is a general road or a highway. The control lane direction 317 indicates the traveling direction of the road on which the Orbis device controls. As for the traveling direction, for example, a round of 360 ° with reference to true north may be indicated by a numerical value of 0 to 359.

  Returning to FIG. 1, the map image data storage unit 33 stores image data of a map image provided to the user by the user terminal device 1. In the present embodiment, the map image data storage unit 33 stores map image data in advance. When receiving a request from the user terminal device 1, the map image data stored in the map image data storage unit 33 is transmitted to the user terminal device 1.

  The search area setting unit 35 sets a search area including an area around the route set by the route search engine 11 of the user terminal device 1. For example, the search area setting unit 35 acquires route data indicating the route set by the route search engine 11. The route data is, for example, data in which a plurality of nodes passing from a departure place to a destination are arranged with data indicating node positions (latitude and longitude) in the order of passage. Note that the search area setting unit 35 may be installed in the user terminal device 1.

  FIG. 3 shows an example of the route data 500. The route data 500 includes a route order 501, a node ID 503, and a node position 505 as data items. The order 501 is an order of nodes constituting a route from the departure place (S) to the destination (G). The node ID 503 is identification information of a node included in the route. The node position 505 is the position of each node, and is indicated by latitude and longitude.

  Returning to FIG. 1 again, the search area setting unit 35 may set a search area by combining a plurality of rectangles centered on a point on the route. For example, the search area setting unit 35 may select points on the route at predetermined intervals, and set a search area by combining a plurality of rectangles (unit areas) centered on the selected points. Details of the search area setting will be described later.

  The orbis extraction unit 37 extracts one or more orbis devices installed in the search area set by the search area setting unit 35 as candidate orbis devices. For example, the Orbis extraction unit 37 specifies the Orbis ID 311 using the Orbis apparatus whose installation position 313 is within the search area as a candidate Orbis apparatus. The search area setting unit 35 acquires data records related to the orbis ID 311 of the candidate orbis device from the orbis data 310 and transmits these to the user terminal device 1 as candidate orvis data 900. The orbis data storage unit 31 and the orbis extracting unit 37 may be mounted on the user terminal device 1.

  FIG. 4 is a schematic diagram showing the route set by the route search engine 11 and the arrangement of the Orbis device for the route. FIG. 5 is an explanatory diagram of a search area in the situation shown in FIG. Hereinafter, setting of the search area 600 and extraction of the orvis will be described with reference to FIGS. 4 and 5.

  First, FIG. 4 shows a route R that goes through the nodes N1 to N6 in this order from the departure point (S) to the destination (G). On the way, between the nodes N4 and N5 is a highway. Further, in FIG. 4, the orbis devices O <b> 1 to O <b> 11 are displayed with arrows indicating the enforcement lane direction 317 at positions corresponding to the respective installation positions 313. The road type 315 of the Obis devices O6 and O7 is a highway, and the other is a general road.

  In such a case, the search area setting unit 35 sets the search area 600 by arranging rectangular unit areas 601 to 612 centering on a plurality of points on the route R as shown in FIG. The center points of the rectangular unit areas 601 to 612 may be set on the route R every predetermined distance. Here, the rectangular unit areas 601 to 612 are all square, but may be rectangular. When the search area setting unit 35 sets the search area by combining the unit areas so that the search area from the departure point to the destination is not interrupted, the narrowest part of the search area has a predetermined distance or more. In addition, the length of one side of the square and the distance between the center points of each square may be determined.

  FIG. 6 is an explanatory diagram showing the relationship between the length of one side of the unit area and the distance between the center points of the unit area. A relationship between the length of one side of the unit area and the distance between the center points of the unit area will be described with reference to FIG.

In the figure, when the two unit areas 613 and 614 having the points on the route R as the center points C1 and C2 are arranged so as to overlap, the width of the overlapping area (the hatched area in the figure) is the narrowest. That is, a case is shown in which the diagonal lines of the two unit areas coincide with each other. When a plurality of rectangular unit areas are combined and continuous so that the search area is not interrupted, the width of the search area 600 is the narrowest when the positional relationship shown in FIG. At this time, the distance from the route R in the place where the search area 600 is the narrowest is a, the length of one side of the square is b, and the distance between the center points is X. At this time, the following equation holds.

  Here, if the distance a at which the distance from the route R is the shortest is 500 m and the length b of one side of the square is 3 km, the distance X between the center points is about 3.24 km. Further, the length b of one side of the square may vary depending on the region. For example, in urban areas, the length b of one side of the square may be shorter than in the suburbs. The determination as to whether it is an urban area or a suburb may be made based on, for example, the number of predetermined map symbols (for example, convenience stores) existing within a predetermined range in the map.

  Returning to FIG. 1 again, for each unit area, the orbis extraction unit 37 determines whether or not an orbis device exists in each unit area, and extracts orbis devices that exist in all search areas. . For example, based on the latitude and longitude of the two vertices located at the opposite corners of each unit area, the orbis extraction unit 37 identifies the orbis ID 311 of the orvis device whose installation position 313 falls within that unit area. In the example of FIG. 5, among the Orbis devices O1 to O11, the Orbis devices O4, O5, and O8 are outside the search area 600, and the other Orbis devices (O1 to O3, O6, O7, and O9 to O11) are candidate orbis. Extracted as a device.

  The user terminal device 1 includes a route search engine 11, an orbit selection unit 13, an alarm target orbis data storage unit 15, a display control unit 16, a sound output control unit 17, an alarm determination unit 18, and a GPS processing unit 19. And have.

  The route search engine 11 sets a route from the departure point to the destination. For example, when the route search engine 11 receives a route search request specifying a departure place and a destination from the input device 101, the route search engine 11 performs a route search from the specified departure place to the destination. When a plurality of routes are searched, one of them is set according to the user's selection. For example, in the route search request, the starting point and the destination may be specified by latitude and longitude. As the route search engine 11 used in the present embodiment, a well-known route search engine used in a general navigation system or the like may be used. The route search engine 11 transmits route data 500 of the set route to the server 3. The route search engine 11 may be mounted on the server device 3.

  The orbis selecting unit 13 selects one or more orbis devices extracted by the orvis extracting unit 37 of the server 3 that matches the installation direction and the traveling direction of the road in the route section corresponding to the installation position. To do.

  For example, the orbis selection unit 13 first acquires the candidate orbis data 900 described above from the orbis extraction unit 37. Further, the orvis selection unit 13 acquires the route data 500 set by the route search engine 11. Then, the orbis selecting unit 13 selects an orvis device that affects the set route with respect to one or more orvis devices included in the candidate orvis data 900. A specific selection method will be described later. The orbis selection unit 13 may be mounted on the server device 3.

  The orbis device selected by the orvis selecting unit 13 is set as the alarm target orbis device, and the orbis data is stored in the alarm target orvis data storage unit 15. The data item of the orbit data stored here may be the same as the data item of the orvis data storage unit 31.

  With reference to FIG. 7, the selection method of an alarm target orbis apparatus is demonstrated in detail.

  First, the orbis selection unit 13 performs the following processing for each candidate orvis device included in the candidate orvis data 900. That is, the orbis selection unit 13 specifies the installation position 313 of the candidate orbis device. The orvis selecting unit 13 refers to the node position 505 in the route data 500 and extracts the nearest node (nearest node) from the installation position 313 of the candidate orvis device. Here, the orbis selection unit 13 specifies two links adjacent to the nearest node in the set route, and calculates the direction thereof. In the example of FIG. 6, the nearest node of the installation position 313 of a certain candidate orbis device is the node Nx, the adjacent links are links L1 and L2, and the directions thereof are V1 and V2. The directions of the links L1 and L2 may be obtained from the installation positions of the nodes Nx−1, Nx, and Nx + 1 as V1 and V2.

  If the candidate lane direction 317 of the candidate orbis device targeted here matches one or both of the directions V1 and V2 of the links L1 and L2, the orbis selection unit 13 selects the candidate orbis. . Here, “matching” means that the direction difference is within a predetermined range in addition to the case where the directions are completely matched. In the example of FIG. 7, the control lane direction 317 and the directions V1 and V2 of the links L1 and L2 are matched.

  In the example of FIG. 5, the Orbis devices O1, O7, O9, and O10 are selected by the matching in the above direction.

  The orbis selecting unit 13 automatically matches the road type and the road type of the road in the route section corresponding to the installation position among the one or more orbis devices extracted by the orbit extracting unit 37 of the server 3. Select a speed enforcement device. For example, among the Orbis devices that are determined to match the direction of the control lane 317 and the direction of the road in the corresponding route section as described above, the road type 315 further matches the type of the road in the corresponding route section. Choose one.

  In the example of FIG. 5, from the Orbis devices O1, O7, O9, and O10 having the same direction, the Orbis devices O1, O7, and O10 having the same road type are selected by the above-described road type matching. As a result, it is possible to extract only the Orbis device that affects the vehicle traveling on the set route, that is, the section within the route that is the target of control.

  In this embodiment, the link adjacent to the nearest node is a route section corresponding to the installation position 313 of the candidate orbis device, but the installation position 313 of the candidate orbis device and the route section are associated with each other by other methods. May be. For example, a plurality of (for example, two or three) nodes may be selected in the order closer to the installation position 313 of the candidate orbis device, and the link between these nodes may be a corresponding route section, or the installation location 313 of the candidate orbis device It is also possible to use the nearest link as the corresponding route section.

  The alarm target orbis data storage unit 15 stores the orbis data included in the candidate orbis data 900 for the orvis device selected by the orbis selecting unit 13. Orvis data stored in the alarm target orvis data storage unit 15 does not need to be matched with nodes or links, and may exist independently of other data.

  The GPS processing unit 19 detects the current position of the user terminal device 1 based on a GPS signal received by a GPS antenna (not shown). This current position is specified by latitude and longitude, for example. The GPS processing unit 19 measures the current position at a predetermined timing such as when receiving an instruction from the user at a predetermined time interval. In the present embodiment, the current position is specified using GPS, but other than this, for example, radio waves transmitted from a base station of a mobile phone, radio waves transmitted from a base station of a wireless LAN, etc. May be used to identify the current position.

  The display control unit 16 causes the display device 102 to display various screens. For example, the display control unit 16 causes the display device 102 to display a map image based on the map image data acquired from the server 3. At that time, a route display indicating the route set by the route search engine 11 and a current position display indicating the current position detected by the GPS processing unit 19 may be displayed superimposed on the map image. Further, during navigation, the map image to be displayed on the display device 102 may be scrolled as the current position of the user terminal device 1 moves, and the traveling direction may be on the screen. A heading-up display that rotates the map image may be performed.

  The display control unit 16 may further perform an orbis display at a position corresponding to the installation position on the map image for the alarm target orvis device stored in the alarm target orvis data storage unit 15. An example of the Orvis display on the map image is shown in FIG. In the example shown in the figure, the orbis display 710 is superimposed on the map image on the normal navigation screen 700. Thereby, the user who has seen the map image during navigation can visually grasp the presence of the orvis installed along the route.

  The sound output control unit 17 performs control for outputting sound such as voice or music from the speaker 103. For example, the sound output control unit 17 outputs a predetermined sound when the alarm determination unit 18 determines that an alarm output is necessary. In the present embodiment, it is possible to output an alarm using sounds of various modes such as voice, music, and warning sound. For example, an interface screen 800 as shown in FIG. 9 can be displayed on the display device 102 to allow the user to select which output mode to use. The sound output control unit 17 causes the speaker 103 to output the sound selected on the interface screen 800.

  The alarm determination unit 18 determines whether or not it is necessary to output information (alarm) for notifying the presence of Orbis. For example, the alarm determination unit 18 has the current position detected by the GPS processing unit 19 upstream of the installation position of the alarm target orvis device, and the detected current position and the installation position of the alarm target orvis device. It is determined whether the distance is equal to or less than a predetermined distance. That is, the alarm determination unit 18 determines that an alarm output from the speaker 103 is necessary at this time. The distance at which the alarm output is required may be longer on the expressway than on the general road. The alarm determination unit 18 may determine that the alarm needs to be output until the current position detected by the GPS processing unit 19 passes the position of the target orvis device.

  A processing procedure in the navigation system having the above configuration will be described with reference to a flowchart.

  FIG. 10 shows a navigation preparation process executed before starting navigation.

  First, the server 3 acquires orbis data via a predetermined interface means and stores it in the orvis data storage unit 31 (S11). This process can be omitted when the Orvis data is already stored in the Orvis data storage unit 31.

  Next, in the user terminal device 1, when a route search request is input from the user via the input device 101, the route search engine 11 performs a route search in response to the route search request and sets a route (S13). ).

  When the route data 500 indicating the route set here is transmitted from the user terminal device 1 to the server 3, the server 3 performs a search for the search area setting unit 35 to search for the Orbis device existing in the vicinity of the route. An area is set (S15).

  The Orbis extraction unit 37 refers to the Orbis data storage unit 31 and extracts the Orbis device in the search area set in Step S15 (S17). The orbis device extracted here is a candidate orbis device that is a candidate for an alarm target. Candidate orvis device data 900 is transmitted to user terminal device 1.

  In the user terminal device 1, the orbis selecting unit 13 selects an alarm target orvis device that affects a vehicle traveling on the set route from the candidate orbis devices (S19). Data of the selected alarm target orvis device is stored in the alarm target orvis data storage unit 15.

  As a result, it is possible to extract only the Orbis device that controls the set route from the Orvis data independent of the route search engine or the road map. Thereby, the Orvis data can be updated to the latest data at a timing different from that of the route search engine or the road map.

  FIG. 11 is a flowchart illustrating a processing procedure for the user terminal device 1 to output an alarm from the speaker 103 during navigation.

  The GPS processing unit 19 detects the current position (S31).

  The alarm determination unit 18 refers to the alarm target orvis data storage unit 15 to determine whether or not the alarm target orvis device exists within a predetermined distance ahead of the current position (S33). If there is no alarm target orbis within a predetermined distance ahead of the current position, the process returns to step S31.

  When the alarm target orbis exists within a predetermined distance ahead of the current position (S33: Yes), the sound output control unit 17 outputs a predetermined alarm from the speaker 103 (S35).

  The user terminal device 1 performs the above processing until the navigation ends (S37).

  Thus, during navigation, it is possible to notify the presence of an Orbis device whose control target is the route ahead of a vehicle running with the user terminal device 1 mounted thereon.

  The above-described embodiments of the present invention are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to those embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.

  In addition, although the navigation system according to the present embodiment is configured to be distributed in the user terminal device 1 and the server 3, it may be realized by mounting all functions in the user terminal device 1. Or even if it is a case where it comprises with user terminal unit 1 and server 3, you may perform functional allocation of a mode different from this embodiment to user terminal unit 1 and server 3.
