  The terminal device 200 is an information processing apparatus having a function of intermittently acquiring probe information intermittently by, for example, a GPS (Global Positioning System) or the like, and transmitting the probe information to the information processing apparatus 100 via the network 400. As shown in FIG. 1, the terminal device 200 displays a main control unit 220 including a CPU and a memory, a communication unit 240 for connecting to the network 400, an input unit 210 such as a touch panel for receiving an operation from a user, and a screen. It is preferable that the display unit 250 includes a positioning unit 260 that measures current position information.

  Probe information refers to information including user ID, positioning time, latitude / longitude, and the like. Here, as an interval at which the terminal device 200 transmits the probe information to the information processing system 10, for example, an interval of 5 minutes or an interval of 10 minutes can be considered, but it is not limited thereto. Also, it does not matter whether the interval is regular or irregular.

  Specifically, the terminal device 200 is a mobile phone (whether it is a so-called smart phone or a feature phone), a tablet, a notebook PC (Personal Computer), a PDA (Personal Data Assistance), a game machine, Although a car navigation apparatus etc. are assumed, it is not restricted to these. For example, it may be a terminal device such as a desktop PC which does not have portability. It is desirable that the user can use the navigation service by installing a navigation application (hereinafter referred to as a navigation application) on the terminal device 200. The navigation service is a service provided by the information processing apparatus 100 for providing a route guidance to a destination for the user.

  Each configuration of the information processing apparatus 100 for realizing such a navigation service will be described. As shown in FIG. 1, the information processing apparatus 100 includes an input unit 110, a control unit 120, a storage unit 130, and a communication unit 140.

  The input unit 110 is configured to receive an operation from a manager of the information processing apparatus 100, and can be realized by a keyboard, a mouse, a touch panel, or the like.

  The communication unit 140 is configured to connect the information processing apparatus 100 to the network 400. For example, the communication unit 140 can be realized by a LAN card, an analog modem, an ISDN modem, or the like, and an interface for connecting them with the processing unit via a transmission path such as a system bus. Further, the display unit 150 is configured of a display or the like.

  The control unit 120 includes an arithmetic processing unit 121 such as a CPU and an MPU, a memory 122 such as a RAM, and an image processing unit (not shown). The arithmetic processing unit 121 operates various functional units by executing a program stored in the storage unit 130 based on various inputs. This program may be stored in a recording medium such as a CD-ROM, or may be distributed via a network 400 and installed on a computer. The memory 122 is for temporarily storing a server program and various data required for operations and the like during execution of processing in the program.

  The storage unit 130 is configured by a storage device such as a hard disk, and stores various programs necessary for executing the processing in the control unit 120, data required for executing the various programs, and the like. Specifically, as for storage part 130, it is desirable to have behavior analysis information DB131 and house information DB132.

  In the behavior analysis information DB 131, analysis results of probe information collected from the terminal device 200 are accumulated. Specifically, the analysis unit 1211 to be described later analyzes information such as positioning time and latitude / longitude included in the probe information for each user, and the behavior analysis information DB 131 includes a mesh including the user's home, work location It is desirable to store mesh etc.

  A mesh is a plurality of divided areas obtained by dividing a map based on latitude and longitude. In the present embodiment, although the mesh is described as a square area, the present invention is not limited to this, and the shape and size of the mesh divided area can be appropriately set according to the specification and design. For example, the shape of the mesh can be an area surrounded by a polygon such as a quadrangle, a hexagon, a rhombus, or a curve such as a circle. Also, the size of the mesh may not be constant. For example, the size of the mesh can be set large if the user wants to specify a mesh frequently staying, while the size of the mesh can be set small if it is desired to specify a store or the like frequently visited by the user. Also, for example, the mesh in the urban area may be made smaller (more finely). In addition, the size of the mesh may be changed for each area according to the demographic information (for example, the mesh of the area with a large population may be reduced), or the size may be set based on the classification of municipality, residential area type, etc. . In addition, although a 25-meter square mesh is desirable in this embodiment, it is not limited to this.

  FIG. 2A is a diagram showing an example of the behavior analysis information DB 131. As shown in FIG. As shown in FIG. 2A, in the behavior analysis information DB 131, the user ID, the home mesh, and the work area mesh are registered in association with each other. In the example of FIG. 2A, the minimum latitude and longitude of the mesh and the maximum latitude and longitude of the mesh are registered as the mesh. However, the present invention is not limited thereto. For example, a mesh code may be registered. The latitude and longitude of the home and the latitude and longitude of the work location may be registered instead of the home mesh and the work location mesh.

  FIG. 2B is a diagram showing an example of the house information DB 132. As shown in FIG. As shown in FIG. 2 (B), in the housing information DB 132, information indicating the position of the residential area and the residential area ID are registered in association with each other. The residential area is an area determined to be a residential area by the processing of the determination unit 1212 described later. As information indicating the position of the residential area, for example, it is desirable that the minimum latitude longitude of the mesh and the maximum latitude longitude of the mesh, the mesh code, etc. be registered, but it is not limited thereto. For example, an administrative boundary polygon or an address may be registered as information indicating the position of a residential area.

  Furthermore, as shown in FIG. 1, it is preferable that the arithmetic processing unit 121 includes an analysis unit 1211, a determination unit 1212, a specifying unit 1213, a guiding unit 1214, and a searching unit 1215 as functional units. .

  The analysis unit 1211 analyzes a home mesh at a user's home from the probe information acquired from the terminal device 200 within a predetermined period. The analysis unit 1211 registers the analysis result in the behavior analysis information DB 131. Specifically, the analysis unit 1211 can analyze the mesh in which the user is staying at night based on the positioning time and the latitude and longitude included in the probe information, and can register it in the behavior analysis information DB 131 as a home mesh. Further, the analysis unit 1211 can analyze the mesh in which the user is staying on a weekday, and can register the mesh as a work area mesh in the behavior analysis information DB 131. The analysis unit 1211 may analyze the position of the home or work place not by the mesh but by the latitude and longitude, and may register the latitude and longitude indicating the home position and the work position in the behavior analysis information DB 131.

  The determination unit 1212 determines whether the area is a residential area based on the number of homes included in the area. The determination unit 1212 can use a mesh, an administrative boundary polygon, or the like as an area to be determined whether or not it is a residential area.

  Further, when determining the number of houses, the determining unit 1212 can use a house mesh, a house latitude longitude, a house polygon (data indicating the shape of each house), or the like. For example, in the case of determination using a home mesh, the determination unit 1212 refers to the behavior analysis information DB 131 and counts the number of home meshes partially included in the determination target area as the number of homes. At this time, even if the same mesh is used, it is desirable to count as another home mesh if the tied user IDs are different. When making a determination using home latitude and longitude, the determination unit 1212 refers to the behavior analysis information DB 131 and counts the number of home latitude and longitude where the latitude and longitude are included in the determination target area as the number of homes. Furthermore, when making a determination using house polygons, determination unit 1212 refers to the database in which house polygons are stored, and counts the number of house polygons in which the center point or representative point is included in the determination target area as the number of houses. It is desirable to do. The database in which the housing polygons are stored may be implemented on the storage unit 130 or may be implemented on a system outside the information processing system 10.

  For example, when the determination target area includes the number of houses equal to or greater than the threshold value, the determination unit 1212 can determine that the area is a residential area. Furthermore, the determination unit 1212 may determine whether the area is a residential area based on the density of the houses included in the determination target area.

  Furthermore, the determination unit 1212 determines whether or not the determination target area is a residential area based on the number of residential polygons having a representative point or a central point at a position less than a predetermined distance from the representative point or central point of a certain residential polygon. You may. In this case, if houses are concentrated in one place of the determination target area, it can be determined as a residential area even if the density is low in the entire area. Therefore, for example, it is effective when judging a residential area in a depopulated area such as a country.

  In addition, the determination unit 1212 may register the area designated by the user in the house information DB 132 of the storage unit 130 as a residential area.

  The identifying unit 1213 identifies the current position of the user based on the position information acquired from the terminal device 200 of the user. It is desirable that the specifying unit 1213 specify the current position of the user from the information of the latitude and longitude included in the probe information received from the terminal device 200 via the communication unit 140.

  The guiding unit 1214 notifies the terminal device 200 based on the distance between the identified current position and the stored residential area. The guide unit 1214 guides the user to the route to the destination set by the user, and when the user enters the residential area or exits the residential area, the notification is sent together with the route guidance. It is desirable to do. For example, the guiding unit 1214 refers to the housing information DB 132, and notifies when the distance from the boundary on the moving direction of the stored residential area to the current position specified is within a predetermined distance. Can. Furthermore, the guide unit 1214 determines whether or not the current position is included in the residential area, and if it is not included, the notification to enter the residential area from now on is included in the residential area You can be notified that you will leave the At this time, it is desirable that the guide unit 1214 notify the route guidance together with the route guidance, such as “This is the right. I will enter the residential area ahead”. The notification performed by the guiding unit 1214 is preferably voice, but is not limited to this. For example, characters may be displayed on the display unit 250 of the terminal device 200.

  The search unit 1215 presents a recommended route to a destination in response to a route search request from the user. It is desirable to use weight information of each route for this route search. As parameters of this weight information, it is possible to use information such as distance, general road or toll road. The larger the weight, the easier the route may be recommended.

  Next, the flow of the house information DB 132 creation process of the information processing apparatus 100 will be described using FIG. 3. Note that each processing step included in the flow of processing described below can be arbitrarily changed in order or can be executed in parallel, as long as no contradiction occurs in the processing content. Step may be added. In addition, while the steps described as one step can be divided into a plurality of steps and executed for convenience, those described into a plurality of steps for convenience can be grasped as one step.

  First, the information processing apparatus 100 accumulates probe information transmitted from the terminal device 200 for a certain period. The accumulated probe information for a fixed period is analyzed by the analysis unit 1211 (S101). The analysis unit 1211 identifies the mesh staying at night from the probe information, and registers it in the behavior analysis information DB 131 as a home mesh (S103). The analysis unit 1211 may analyze the latitude and longitude where the home is located, and may register the home latitude and longitude in the behavior analysis information DB 131. The analysis unit 1211 repeats the processes of S101 and S103, and registers home meshes of a plurality of users in the behavior analysis information DB 131.

  Next, the determination unit 1212 extracts an arbitrary area N (S105), and determines whether the area N is a residential area based on the number of home meshes or housing polygons included in the area N (S107). It is desirable that the determination unit 1212 extract the area N in units of meshes or in units of administrative boundary polygons. The determination unit 1212 calculates the density of the area N from the area of the area N and the number of home meshes or housing polygons included in the area N, and the area N is a house based on whether the calculated density is equal to or more than a threshold. It can also be determined whether it is a town or not.

  If the determination unit 1212 determines that the area N is a residential area (S107: YES), the area N is registered as a residential area in the housing information DB 132 (S109). The determination unit 1212 creates a house information DB 132 by repeating the processes from S105 to S109.

Next, the flow of the route guidance process of the information processing apparatus 100 will be described using FIG. 4.
The user operates the terminal device 200 to activate the navigation application installed in advance. Furthermore, the terminal device 200 is operated to set a destination. The setting of the destination may be performed by specifying the latitude and longitude, or may be performed by specifying an arbitrary point on the map.

  When receiving the setting of the destination (S201), the searching unit 1215 searches for a route to the destination, and presents the recommended route to the user according to the weighting (S203). When the user starts moving, the communication unit 140 receives probe information from the terminal device 200 (S205). The identifying unit 1213 identifies the current position of the user from the latitude and longitude included in the received probe information (S207). Next, the guiding unit 1214 determines whether the user has reached the destination based on the identified current position (S209). If the destination has been reached (S209: YES), the route guidance process is ended.

  On the other hand, when the destination has not been reached yet (S207: NO), the guide unit 1214 refers to the house information DB 132, and is within a predetermined distance from the current position, and on the traveling direction of the recommended route. It is determined whether there is an area boundary (S211). If the boundary of the residential area is not within the predetermined distance from the current position in the traveling direction of the recommended route (S211: NO), the guiding unit 1214 performs normal route guidance (S213).

  If the boundary of the residential area is within a predetermined distance from the current position (S211: YES), the guide unit 1214 checks whether the current position is included in the residential area (S223). When the current position is included in the residential area (S223: YES), the guiding unit 1214 notifies that the user is about to leave the residential area in addition to the route guidance (S225). If the current position is not included in the residential area (S223: NO), the guide unit 1214 gives a route guidance and then notifies that the residential area will be approached soon (S235). Specifically, it is desirable to perform two-step guidance such as, for example, "This is the right. I will enter the residential area ahead". The processes of S205 to S235 are repeated until the goal is reached.

  As described above, according to the information processing apparatus 100 according to the present embodiment, when the user enters a residential area, a notice can be issued by performing notification.
