In the following, for ease of understanding, an embodiment in which the present invention is realized using an information processing apparatus will be described as an example. However, as described above, the present invention is not limited thereto.

  FIG. 1 is a system configuration diagram of an information processing system 10 including an information processing apparatus 100 according to the present embodiment. As shown in FIG. 1, the information processing apparatus 100 and the terminal apparatus 200 are set to be communicable with each other via a network 400 such as the Internet or a dedicated line, thereby configuring a map display system. The network 400 is configured by a wireless network or a wired network. Examples of communication networks include mobile phone networks, PHS (Personal Handy-phone System) networks, wireless LAN (Local Area Network), 3G (3rd Generation), LTE (Long Term Evolution), 4G (4th GenerationMex), (Registered Trademark), infrared communication, Bluetooth (Registered Trademark), wired LAN, telephone line, power line network, IEEE 1394, and other networks.

  The terminal device 200 is an information processing device having a function of intermittently acquiring probe information using, for example, GPS (Global Positioning System) or the like and transmitting the probe information to the information processing device 100 via the network 400. As illustrated 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 that receives an operation from a user, and a screen. It is preferable to include a display unit 250, a positioning unit 260 that measures current position information, and the like.

  The probe information is information including a 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, a 5-minute interval, a 10-minute interval, or the like is conceivable, but is not limited thereto. It does not matter whether the interval is regular or irregular.

  Specifically, the terminal device 200 includes 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, A car navigation device or the like is assumed, but is not limited thereto. For example, it may be a terminal device such as a desktop PC that 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) in the terminal device 200. The navigation service refers to a service provided by the information processing apparatus 100 that provides route guidance to a destination for a user.

  Each configuration of the information processing apparatus 100 for realizing such a navigation service will be described. As illustrated 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 an administrator 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, and the like, and an interface for connecting them to the processing unit via a transmission line such as a system bus. The display unit 150 includes a display or the like.

  The control unit 120 includes an arithmetic processing unit 121 such as a CPU or 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 recorded in the storage unit 130 based on various inputs. This program may be stored in a recording medium such as a CD-ROM, or distributed via the network 400 and installed in a computer. The memory 122 is for temporarily storing various types of data necessary for computation and the like during execution of processing in the server program and the program.

  The storage unit 130 is configured by a storage device such as a hard disk, and records various programs necessary for executing processing in the control unit 120, data necessary for executing the various programs, and the like. Specifically, it is desirable that the storage unit 130 includes a behavior analysis information DB 131 and a housing information DB 132.

  In the behavior analysis information DB 131, analysis results of probe information collected from the terminal device 200 are accumulated. Specifically, an analysis unit 1211 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 and a workplace. It is desirable to accumulate meshes.

  A mesh refers to a plurality of divided areas obtained by dividing a map based on latitude and longitude. In the present embodiment, the mesh is described as a square area, but the present invention is not limited to this, and the shape and size of the mesh divided area can be appropriately set according to specifications and design. For example, the mesh shape can be a region surrounded by a polygon such as a quadrangle, a hexagon, or a rhombus, or a curve such as a circle. Moreover, the size of the mesh may not be constant. For example, when the user wants to specify a frequently staying mesh, the size of the mesh can be set large. On the other hand, when the user wants to specify a store or the like frequently visited, the mesh size can be set small. For example, the urban mesh may be made smaller (finer). In addition, the size of the mesh may be changed for each region according to demographic information (for example, the mesh in a region with a large population is made smaller), or the size may be set based on the classification of the municipality, the type of residential land, etc. . In this embodiment, a 25-meter square mesh is desirable, but the present invention is not limited to this.

  FIG. 2A is a diagram illustrating an example of the behavior analysis information DB 131. As shown in FIG. 2A, in the behavior analysis information DB 131, a user ID, a home mesh, and a work place mesh are associated and registered. In the example of FIG. 2A, the minimum latitude / longitude and maximum latitude / longitude of the mesh are registered as a mesh, but the present invention is not limited to this, and for example, a mesh code may be registered. Note that the latitude and longitude of the home and the latitude and longitude of the work place may be registered instead of the home mesh and the work place mesh.

  FIG. 2B is a diagram illustrating an example of the housing information DB 132. As shown in FIG. 2B, 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 that is determined to be a residential area by processing of the determination unit 1212 described later. As information indicating the position of the residential area, it is desirable that, for example, the minimum latitude and longitude of the mesh, the maximum latitude and longitude, a mesh code, and the like are registered, but the present invention is not limited to this. For example, administrative boundary polygons and addresses may be registered as information indicating the position of a residential area.

  Furthermore, as illustrated in FIG. 1, the arithmetic processing unit 121 preferably includes an analysis unit 1211, a determination unit 1212, a specification unit 1213, a guide unit 1214, and a search unit 1215 as functional units. .

  The analysis unit 1211 analyzes the home mesh where the user is home from the probe information acquired from the terminal device 200 within a certain period. The analysis unit 1211 registers the analysis result in the behavior analysis information DB 131. Specifically, the analysis unit 1211 can analyze a mesh where the user is staying at night from the positioning time and latitude / longitude included in the probe information, and register the mesh as a home mesh in the behavior analysis information DB 131. Moreover, the analysis part 1211 can analyze the mesh in which the user is staying in the daytime of a weekday, and can register it in action analysis information DB131 as a work place mesh. The analysis unit 1211 may analyze the position of the home or work place by using the latitude and longitude instead of the mesh, and register the latitude and longitude indicating the home position and the work place position in the behavior analysis information DB 131.

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

  Further, when determining the number of houses, the determination unit 1212 can use a home mesh, a home latitude / longitude, a house polygon (data indicating the shape of each house), and the like. For example, when determining using a home mesh, the determination unit 1212 refers to the behavior analysis information DB 131 and counts the number of home meshes that are partly included in the determination target area as the number of houses. At this time, even if the meshes are the same, it is desirable to count them as different home meshes if the linked user IDs are different. When determining using home latitude and longitude, the determination unit 1212 refers to the behavior analysis information DB 131 and counts the number of home latitudes and longitudes whose latitude and longitude are included in the determination target area as the number of houses. Further, when the determination is made using the house polygon, the determination unit 1212 refers to the database in which the house polygon is stored, and counts, for example, the number of house polygons including a center point and a representative point as the number of houses in the determination target area. It is desirable to do. The database storing the house polygons may be configured on the storage unit 130 or may be configured on a system outside the information processing system 10.

  For example, the determination unit 1212 can determine that the area is a residential area when the determination target area includes the number of houses equal to or greater than a threshold value. Furthermore, the determination unit 1212 may determine whether or not the area is a residential area based on the density of the houses included in the determination target area.

  Further, the determination unit 1212 determines whether the determination target area is a residential area based on the number of residential polygons having a representative point or center point at a position less than a predetermined distance from a representative point or center point of a certain house polygon. You may do that. In this case, if the houses are concentrated in one place in the determination target area, it can be determined as a residential area even if the density of the entire area is low. Therefore, for example, it is effective when determining a residential area in a depopulated area such as the countryside.

  The determination unit 1212 can also register the area specified by the user in the housing information DB 132 of the storage unit 130 as a residential area.

  The specifying unit 1213 specifies the current position of the user based on the position information acquired from the user terminal device 200. The specifying unit 1213 preferably specifies the current position of the user from the latitude and longitude information included in the probe information received from the terminal device 200 via the communication unit 140.

  The guide unit 1214 notifies the terminal device 200 based on the distance between the identified current position and the stored residential area. The guidance unit 1214 guides the route to the destination set by the user, and notifies the user together with the route guidance when the user enters or exits the residential area. It is desirable to do. For example, the guide unit 1214 refers to the housing information DB 132 and notifies when the distance from the boundary on the traveling direction of the stored residential area to the identified current position is within a predetermined distance. Can do. Further, the guide unit 1214 determines whether or not the current position is included in the residential area. If not, the guidance unit 1214 notifies the user that the residential area will be entered. You can be notified of leaving. At this time, it is desirable for the guidance unit 1214 to make a notification together with the route guidance, for example, “This is right ahead. Note that the notification performed by the guide unit 1214 is preferably a 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 refers to a unit that presents a recommended route to the destination in response to a route search request from the user. It is desirable to use the weight information of each route for this route search. For the weight information parameter, it is possible to use information such as distance, whether it is a general road or a toll road. The higher the weight, the easier the route may be recommended.

  Next, the flow of the housing information DB 132 creation process of the information processing apparatus 100 will be described with reference to FIG. Each processing step included in the processing flow described below can be executed in any order or in parallel as long as there is no contradiction in the processing contents. These steps may be added. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided 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 apparatus 200 for a certain period. The accumulated probe information for a certain 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). Note that the analysis unit 1211 may analyze the latitude and longitude where the home is located, and 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 the 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 residential polygons included in the area N (S107). The determination unit 1212 desirably extracts the area N in units of meshes or 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 house polygons included in the area N, and the area N is a house based on whether the calculated density is equal to or greater than a threshold value. It can also be determined whether the city.

  When determining that the area N is a residential area (S107: YES), the determining unit 1212 registers the area N as a residential area in the residential information DB 132 (S109). By repeating the processes from S105 to S109, the determination unit 1212 creates the house information DB 132.

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

  When the destination setting is accepted (S201), the search unit 1215 searches for a route to the destination, and presents a recommended route to the user according to the weighting of each route (S203). When the user starts moving, the communication unit 140 receives probe information from the terminal device 200 (S205). The specifying unit 1213 specifies the current position of the user from the latitude and longitude included in the received probe information (S207). Next, the guide unit 1214 determines whether or not 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 ends.

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

  When 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 guide unit 1214 notifies that it will soon leave the residential area in addition to the route guidance (S225). When the current position is not included in the residential area (S223: NO), the guide unit 1214 provides route guidance and notifies that the residential area will be entered soon (S235). Specifically, for example, it is desirable to provide two-step guidance such as “It is right ahead. The processes from S205 to S235 are repeated until the goal is reached.

  Thus, according to the information processing apparatus 100 according to the present embodiment, when the user enters the residential area, the user can be alerted by giving a notification.

[Other embodiments]

  For example, in the above-described embodiment, the configuration in which the determination unit 1212, the specification unit 1213, the guide unit 1214, the search unit 1215, and the house information DB 132 are mounted on the information processing apparatus 100 has been described. However, the present invention is not limited to this, and some or all of these functional units may be mounted on the terminal device 200.

  Further, in the above-described embodiment, as an example, the guide unit 1214 notifies the user when the distance from the boundary in the traveling direction of the stored residential area to the identified current position is within a predetermined distance. The configuration to be described was explained. However, it is not limited to this, For example, it is good also as a structure which registers the distance used as a threshold value about each residential area in the housing information DB132. In this case, when the identified current position is not included in the residential area, the guide unit 1214 enters the residential area when the distance between the current position and the center point of the residential area is less than the threshold value. May be notified. When the current position is included in the residential area, the guide unit 1214 may notify the escape from the residential area when the distance between the current position and the center point of the residential area is equal to or greater than a threshold value.
