  First, the control unit 113 of the information collecting unit 110 in the server 100 selects a complex facility (hereinafter, also referred to as “target facility”) that is a target for maintaining store location information (step S151). Next, the control unit 113 collects the probe information group in the mobile phone 200 in which the store occupying the target facility is set as the destination (target store) from the probe information DB 114 of the storage device 118 (step S152). . Next, the control unit 113 determines whether or not the number of probe information groups in the target facility stored in the probe information DB 114 is greater than a predetermined value (step S153). When the number of probe information groups is equal to or less than the predetermined value (step S153: NO), the control unit 113 does not perform store location information maintenance on the target facility, and sets all remaining complex facilities as information maintenance targets. It is determined whether it has been selected (step S156), a new target facility is selected (step S151), and the processing of step S152 and step S153 is performed similarly. When the number of probe information groups is greater than the predetermined value (step S153: YES), the control unit 113 detects a common area CM in the target facility, for example, a facility such as an escalator or a toilet (step S160). Details of the common area CM detection process in the target facility will be described later. The common area CM corresponds to a specific area in the present invention.

  Next, the control unit 113 selects a target store (hereinafter referred to as “target store”) from which the store position in the target facility is estimated (step S154), and estimates the position of the target store (step S170). Details of the process of estimating the position of the target store will be described later.

  Next, the control unit 113 selects all stores that move into the target facility as the target stores, and determines whether the store position has been estimated (step S155). When all the stores are not selected in step S155 (step S155: NO), the control unit 113 selects a new target store (step S154), and estimates the position of the target store (step S170). When all stores in the target facility are selected as target stores in step S155 (step S155: YES), the control unit 113 determines whether all complex facilities are selected as target facilities (step S156). When all the complex facilities are not selected in step S156 (step S156: NO), the control unit 113 selects a new target facility (step S151), and similarly performs the processing after step S152. When all the complex facilities are selected in step S156 (step S156: YES), the process of maintaining the information on the store location in the complex facility is ended.

A-5. Common area CM detection processing in a complex facility:
FIG. 7 is an explanatory diagram showing a flow of processing (step S160 in FIG. 6) for detecting the common area CM in the complex facility. In this process, the control unit 113 of the information collection unit 110 in the server 100 detects a common area CM in the complex facility by performing statistical processing on a plurality of probe information groups stored in the probe information DB 114 of the storage device 118. To do.

  First, the control unit 113 selects one probe information group for performing statistical processing from the probe information DB 114 (step S161). Next, the control unit 113 performs statistical processing on the selected probe information group and extracts a stay position candidate CA of the mobile phone 200 (step S180). Details of the process of extracting the stay position candidate CA performed by the control unit 113 will be described later.

Yes.

  Next, it is determined whether the process of extracting the stay position candidate CA of the mobile phone 200 has been performed on all the probe information groups in the target facility (step S162). When processing is not performed for all the probe information groups in step S162 (step S162: NO), the control unit 113 selects a new probe information group (step S161), and stay position candidates. CA is extracted (step S180). When processing has been performed for all the probe information groups in step S162 (step S162: YES), the control unit 113 uses the common region CM from the plurality of stay position candidates CA extracted from the plurality of probe information groups. Is calculated (step S163). In this embodiment, the process of extracting the stay position candidate CA is performed for all the probe information groups. However, in other embodiments, the probe information group used for calculating the common area CM is selected. May be. For example, when the destinations in a plurality of probe information groups are the same and there is a bias, specifically, when more than half of the stored probe information groups are set with a specific store as the destination The common area CM may be calculated by selecting a probe information group so that the set destination is not biased. This is to prevent the destination from being erroneously determined as the common area.

  FIG. 9 is an explanatory diagram showing an example of the common area CM calculated in the complex facility. FIG. 9 shows a plurality of stay position candidates CA extracted from a plurality of probe information groups with different destination stores. The stay position candidates CA extracted from a certain probe information group are CA1a, CA2a, CA3a, and CA4a, similarly to the stay position candidates CA shown in FIG. In FIG. 9, the stay position candidates CA extracted from another probe information group are indicated as CA1b, CA2b, and CA3b. Further, stay position candidates CA extracted from different probe information groups are indicated as CA1c, CA2c, CA3c. Some of the plurality of stay position candidates CA overlap each other in the target facility. For example, the stay position candidates CA2a, CA2b, and CA2c form a region CM0 where all overlap. Further, the stay position candidates CA4a and CA3c form an overlapping region different from the region CM0. In the present embodiment, among a plurality of stay position candidates CA extracted from a plurality of probe information groups with different target stores, the stay positions are extracted as stay position candidate CAs of a predetermined number or more of mobile phones 200 and their stay positions. A region CM0, where all candidate CAs overlap, is calculated as a common region CM. In other embodiments, the calculation of the common area CM can be variously modified.

  FIG. 10 is an explanatory diagram showing an example of the common area CM in the complex facility. In FIG. 10, the common area CM calculated by the control unit 113 includes a toilet in the common area CM1, a bench in the common area CM2, an escalator in the common area CM3, an elevator in the common area CM4, and a staircase in the common area CM5. ,It is shown. Note that the common area CM is not necessarily calculated. For example, the steps of the common area CM5 may not be calculated as the common area CM5 when there are few users of the mobile phone 200 to use.

  Next, the control unit 113 stores the calculated common area CM (step S164 in FIG. 7), and ends the process of detecting the common area CM in the target facility.

A-6. Extraction process of stay position candidate CA in complex facility:
Next, the process (step S180 in FIG. 7) of extracting the stay position candidate CA in the complex facility (target facility) from the probe information group in the mobile phone 200 will be described. FIG. 11 is an explanatory diagram showing a flow of processing for extracting the stay position candidate CA of the mobile phone 200 in the complex facility. FIG. 12 is an explanatory diagram showing an outline of the extraction of the stay position candidate CA in the complex facility. FIG. 12 shows a plurality of nodes that specify the position of the mobile phone 200 every 30 seconds in one probe information group in the mobile phone 200 in a part of the target facility. As shown in FIG. 12, stores ST11, ST12, ST13, ST14, and ST15 are occupying the target facility, and there is a passage wa adjacent to each store.

  The control unit 113 of the information collection unit 110 in the server 100 collects probe information of the mobile phone 200 that has entered the target facility every 30 seconds, thereby acquiring nodes at a plurality of points in time of the mobile phone 200. First, as illustrated in FIG. 12A, the control unit 113 extracts the first node NDt1 obtained from the plurality of probe information collected in the target facility in order to extract the stay position candidate CA. Is set as the estimation start node NDst (step S181 in FIG. 11).

  Next, the control unit 113 sets the node NDt7 of the probe information collected 180 seconds after the estimation start node NDst as the estimation end node NDed (step S182), and sets the estimation start node NDst and the estimation end node NDed as diagonal lines. An estimation target rectangle SQt1 having a rectangular shape as a vertex is set (step S183). In the present embodiment, the estimation target rectangle is set as one side of the estimation target rectangle as a line substantially parallel to the latitude line, but may be set by another method.

  Next, the control unit 113 calculates the number of nodes of the mobile phone 200 included in the set estimation target rectangle SQt1 (step S184). FIG. 12A shows that two nodes displayed with hatching excluding the estimation start node NDst and the estimation end node NDed are included in the estimation target rectangle SQt1. In this embodiment, the estimation end node NDed is set as a node 180 seconds after the estimation start node NDst. However, in another embodiment, for example, a node 240 seconds after the estimation start node NDst is set as the estimation end node NDed. Alternatively, the estimation start node NDst and the estimation end node NDed may be determined by other methods.

  Next, the control unit 113 determines whether or not the number of nodes of the mobile phone 200 included in the estimation target rectangle SQt1 is greater than or equal to a preset threshold value (step S185). This process can also be said to be a process for detecting that the user who owns the mobile phone 200 stays in a predetermined range area in the complex facility for a certain period or longer. In the present embodiment, 5 is set as the threshold value, but in other embodiments, a different value may be used. As illustrated in FIG. 12A, the number of nodes included in the estimation target rectangle SQt1 is two, which is less than the threshold value 5 (step S185: NO). SQt1 is not stored. Next, the control unit 113 sets each node (NDt1, NDt2,...) In all probe information collected at the target facility as an estimation start node NDst, and the nodes included in the set estimation target rectangle It is determined whether or not the number is compared with the threshold value (step S187). In the determination in step S187, the control unit 113 has only set the estimation target rectangle SQt1 for the node NDt1 and compared the threshold value with the number of nodes included in the estimation target rectangle SQt1 (step S187). Next, the node NDt2 is set as a new estimation start node NDst (step S181).

  When the node NDt2 is set as the estimation start node NDst, the control unit 113 performs the same process as in the case of the node NDt1. As illustrated in FIG. 12B, the control unit 113 sets the node NDt8 180 seconds after the node NDt2 as the estimation end node NDed (step S182), sets the estimation target rectangle SQt2 (step S183), and estimates The number of nodes included in the target rectangle SQt2 is calculated (step S184). Since the number of nodes included in the estimation target rectangle SQt2 is 9 and is equal to or greater than the threshold value 5 (step S185: YES), the control unit 113 stores the estimation target rectangle SQt2 (step S186). Note that the estimation target rectangle stored with the number of nodes included in the estimation target rectangle equal to or greater than the threshold corresponds to the estimation target region in the present invention.

  FIGS. 12C to 12G show the estimation target rectangle and the number of nodes included in the estimation target rectangle when the estimation start node NDst is set as the nodes NDt3, NDt4, NDt9, NDt14, and NDt16. . When the control unit 113 performs the same processing as when the node NDt1 and the node NDt2 are set as the estimation start node NDst, the control unit 113 stores the estimation target rectangles SQt3 and SQt9 (step S186), and the estimation target rectangles SQt4, SQt14 and SQt16 are not stored.

  When the control unit 113 compares the number of nodes included in the estimation target rectangle with the threshold for each node (NDt1, NDt2,...) In all collected probe information (step S187: YES). Next, it is determined whether there is an estimation target rectangle stored in the target facility (step S188). When there is no stored estimation target rectangle (step S188: NO), the control unit 113 ends the process of extracting the stay position candidate CA in the target facility for this probe information group.

  Since the control unit 113 stores the estimation target rectangles SQt2, SQt3, and SQt9 in the target facility (step S188: YES), next, the stay position candidates in the mobile phone 200 based on the estimation target rectangles SQt2, SQt3, and SQt9 CA is calculated (step S189).

  FIG. 13 is an explanatory diagram illustrating an example of the stay position candidate CA calculated in the complex facility. 13 shows each node of the probe information of the mobile phone 200 in a part of the complex facility (target facility), and the estimation target rectangles SQt2, SQt3, and SQt9 shown in FIG. In the present embodiment, as shown in FIG. 13, the control unit 113 calculates a region where all of the estimation target rectangles SQt2, SQt3, and SQt9 overlap as a stay position candidate CA. In other embodiments, the stay position candidate CA may be calculated by a different method from the estimation target rectangles SQt2, SQt3, and SQt9, and the calculation method can be variously modified.

  When calculating the stay position candidate CA in the target facility, the control unit 113 stores the stay position candidate CA (step S190 in FIG. 11), and ends the stay position candidate CA extraction process in the target facility.

A-7. Store location estimation process in the complex:
Next, a process for estimating a store position in a complex facility from a plurality of probe information groups in the mobile phone 200 will be described (step S170 in FIG. 6). FIG. 14 is an explanatory diagram showing a flow of processing for estimating the position of a store as a destination in a complex facility.

  FIG. 15 is an explanatory diagram showing an example of a movement route of the mobile phone 200 in the complex facility. FIG. 15 shows a route Rtb that is a moving route of the user of the mobile phone 200 in which the target store in the target facility is set. The probe information of the mobile phone 200 indicates that the user of the mobile phone 200 enters the first floor 1F at the target facility from the entrance Ent and goes up to the second floor 2F by the detected escalator of the common area CM3. After that, the user of the mobile phone 200 stays at the stay position candidate CA1a, then stops at the toilet in the common area CM1, stays at the stay position candidate CA2a, and then passes through the area Tb2 by the escalator in the common area CM3. Get off at. Thereafter, the user of the mobile phone 200 exits from the exit Exit via the region Tb1.

  As shown in FIG. 15, in the target facility, there are a region Tb1 and a region Tb2 directly above the region Tb1. In the present embodiment, the control unit 113 compares the number of nodes of the mobile phone 200 in the estimation target rectangle with a preset threshold when calculating the stay position candidate CA. A node whose time has elapsed is not counted as the number of nodes to be compared with the threshold even if included in the estimation target rectangle. That is, even if the control unit 113 passes through the region Tb2 and passes through the region Tb1 directly below the region Tb2 after passing through the region Tb2 in the probe information of the mobile phone 200, the node in the region Tb2 is The number of nodes counted in the estimation target rectangle in the region Tb1 is not included, and as a result, the region Tb1 and the region Tb2 are not extracted as the stay position candidates CA. In another embodiment, the setting may be such that the region Tb1 and the region Tb2 are extracted as the stay position candidates CA, and the region Tb1 and the region Tb2 are obtained by collecting probe information in the complex facility three-dimensionally. You may recognize as a separate area | region.

  In this process, first, the control unit 113 extracts a stay position candidate CA obtained by removing the common area CM from the stay position candidates CA in the target facility (step S171 in FIG. 14). The control unit 113 performs the detection of the common area CM in the target facility (the process of A-5) and the extraction of the stay position candidate CA (the process of A-6), and determines the stay position candidate CA excluding the common area CM. Can be extracted.

  FIG. 16 is an explanatory diagram illustrating stay position candidates CA extracted by excluding the common area CM in the complex facility. FIG. 16 shows a stay position candidate CA extracted from a plurality of probe information groups in which the same destination store is set and from which the common area CM is removed. In FIG. 16, the stay position candidates CA1a and CA2a extracted from the probe information group shown in FIG. 15, the stay position candidates CA1b, CA2b and CA3b extracted from different probe information groups, and the stay position candidates CA1c, CA2c and CA3c ,It is shown. Stay position candidates CA2a, CA2b, and CA2c extracted from different probe information groups with the same destination store each have overlapping regions. The control unit 113 estimates the overlapping area as an estimated position area CAst01 that is the position of the target store (step S172 in FIG. 14). The control unit 113 sets the intersection point on the diagonal line in the estimated position area CAst01 as the center Pst01 of the estimated position area CAst01.

  When the position of the target store cannot be estimated (step S173: NO), the control unit 113 ends the process of estimating the store position in the complex facility. When the position of the target store can be estimated (step S173: YES), the control unit 113 newly stores the position estimated in the facility information stored in the facility information DB 115 as the position information of the store ( Step S174). Next, the control unit 113 displays a position coordinate point for displaying the name of the target facility stored in advance in the facility information DB 115 on the map (name display position coordinate point in FIG. 3), and the estimated center Pst01 of the store. , Is determined whether or not (step S175). In step S175, when the position coordinate points to be determined are close to each other (step S175: YES), if the positions of each other are reflected on the map as they are, the name of the target facility and the name of the estimated store are obtained. It is displayed so that it is difficult for the user of the mobile phone 200 to recognize. Therefore, the control unit 113 performs a correction for shifting the display position of the name of the target store (the position coordinate point in the resident store information in FIG. 3) from the estimated store center Pst01, and the position coordinate point stored in the facility information DB 115 (Step S176). In step S175, when the position coordinate points to be determined are not close to each other (step S175: NO), the control unit 113 sets the facility so that the display position of the name of the target store is the estimated store center Pst01. The process of reflecting the position coordinate point stored in the information DB 115 and estimating the store position is terminated.

  FIG. 17 is an explanatory diagram showing an example of a complex facility displayed on a map. 17A and 17B, the shopping center SC is displayed based on the position coordinate points for generating the polygon of the complex facility shown in FIG. 3 in the map MAP image. The name of the complex and the name of each store occupying the complex are displayed on the inside. In FIG. 17A, the store positions of the stores ST01, ST02, ST03 occupying the complex facility can be estimated, and the names of the stores are displayed at position coordinate points that are the store positions. In FIG. 17B, the store position cannot be estimated in any of the stores ST01, ST02, and ST03, and the name of each store is displayed at the position coordinate point of the store registered in advance in the facility information DB 115. In the present embodiment, when the store name is displayed as an image on the map MAP, the name of each store is displayed at the store position in the complex facility. Even when the route guidance ends, the position of the destination store at the destination facility can be known.

  As described above, in the server 100 according to the present embodiment, store information is stored in the facility information DB 115 of the information collection unit 110 in association with various types of information about the complex facility and information on the complex facility at the store included in the complex facility. Has been. The map information DB 127 stores link information, node information, and map image data as image data. The control unit 123 of the route search unit 120 receives the probe information and the destination information of the mobile phone 200 transmitted from the mobile phone 200, searches the route using the complex facility having the destination store as the destination facility, and searches for the route. Route information to the target facility is transmitted to the mobile phone 200. The control unit 113 of the information collecting unit 110 collects probe information of the mobile phone 200 that has arrived at the target facility until the mobile phone 200 leaves the target facility, and stores the probe information in the probe information DB 114. Further, the control unit 113 estimates the position of the target store in the target facility based on the probe information collected from the mobile phone 200. Therefore, in the server 100 according to the present embodiment, the position of each store can be estimated in a complex facility where a plurality of stores are occupying, and convenience can be improved for a user who carries the mobile phone 200. In addition, when the complex facility is displayed on the map MAP, since the position where the name of the tenant is displayed is reflected in the position of each store, the user can easily recognize the position of the target store, and more up to the target store. You can arrive in a short time. Further, in order to enhance the facility information including the store location in the complex facility, the probe information of the mobile phone 200 of the user who uses the complex facility is collected without performing a detailed investigation, thereby Since the position can be estimated, the facility information can be constructed at a lower cost.

  Further, in the server 100 according to the present embodiment, the control unit 113 of the information collection unit 110 performs a common area detection process on the probe information collected from the plurality of mobile phones 200, thereby allowing the user in the complex facility to perform the process. The common area CM to be used is detected, and the position of the target store is estimated from the area excluding the common area CM in the complex facility. Therefore, in the server 100 in this embodiment, the position of the store in the complex facility is not erroneously estimated to the position of the common area CM such as a toilet, and the accuracy of the store position estimation can be improved.

  Moreover, in the server 100 in this embodiment, the control part 113 of the information collection part 110 receives the probe information of the mobile phone 200 every 30 seconds. In addition, the control unit 113 sets an estimation target rectangle when it is determined that the predetermined area in the complex facility has stayed for a certain period of time, and sets a region where the estimation target rectangle overlaps in one probe information group as a stay position candidate. Extract as CA. The control unit 113 estimates an area where the stay position candidates CA overlap in the probe information group in which the same destination store is set as the location of the destination store. Therefore, in the server 100 in this embodiment, the position of the target store can be estimated from the probe information group of the mobile phone 200 in which the target store is set, and it is not necessary to conduct a detailed investigation to know the store position in the complex facility. The store position can be easily estimated.

B. Variations:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

B1. Modification 1:
In the above embodiment, as shown in FIG. 13, the control unit 113 of the information collecting unit 110 in the server 100 calculates a region where all of the estimation target rectangles SQt2, SQt3, and SQt9 overlap as the stay position candidate CA. The method for calculating the stay position candidate CA is not limited to this, and various modifications can be made. For example, the estimation target rectangle having the largest number of nodes included in the estimation target rectangle may be calculated as the stay position candidate CA. In this calculation method, the estimation target rectangles SQt2, SQt3, and SQt9 shown in FIG. 13 include nine nodes having the largest estimation target rectangles SQt2 and estimation target rectangles SQt3. Calculate as position candidate CA. At this time, if the number of nodes included in the estimation target rectangle is the same, the stay position candidate CA may be determined according to the size of the area.

  Moreover, the control part 113 may calculate the area | region where most estimation object rectangles overlap among the set several estimation object rectangles as stay position candidate CA. In this modification, since the region where all of the estimation target rectangles in this embodiment overlap is calculated as the stay position candidate CA, for example, a certain estimation target rectangle SQt2 ′ and a different estimation target rectangle SQt3 ′ overlap. Even if it does not have a portion, the stay position candidate CA can be calculated.

  FIG. 18 is an explanatory diagram showing an example of the stay location candidate CA of the mobile phone 200 ′ extracted in the complex facility. FIG. 18 shows a plurality of nodes that specify the position of the mobile phone 200 every 30 seconds in the probe information of the mobile phone 200 ′ in a part of the target facility. In FIG. 18, the control unit 113 of the information collecting unit 110 in the server 100 sets the estimation start node NDst as the node NDt2 ′, and sets the estimation end node NDed as the node NDt8 ′ 180 seconds after the node NDt2 ′. . In the estimation target rectangle SQt2 ′ set by the estimation start node NDst and the estimation end node NDed in this modified example, the number of nodes included in the estimation target rectangle SQt2 ′ is 6, and is greater than or equal to a preset threshold value of 5 or more. is there. However, as shown in FIG. 18, the estimation target rectangle SQt2 'is on the passage wa, and is not desirably extracted as the stay position candidate CA of the mobile phone 200' and considered in the store position estimation process. Therefore, in this modification, in the estimation target rectangle SQt2 ′ set by the estimation start node NDst and the estimation end node NDed, a numerical value obtained by dividing the length of the other short side from the length of the long side is a predetermined value. In the above case (for example, 4 or more), the control unit 113 regards the estimation target rectangle SQt2 ′ as the passage wa and does not calculate the stay position candidate CA. In this modified example, when the store position is estimated, the passage wa can be excluded in advance, so that the store position can be estimated with high accuracy by estimating the store position.

  In addition, when a certain estimation target rectangle SQt is extremely small and a small estimation target rectangle SQt is continuously set for a certain time or more, the estimation target rectangle SQt may not be calculated as the stay position candidate CA. For example, when the user of the mobile phone 200 is waiting for another user, the estimation target rectangle SQt is an extremely small rectangle for a certain period of time. At this time, the estimation accuracy of the store position can be improved by not calculating the estimation target rectangle SQt as the stay position candidate CA. Further, even if the estimation target rectangle SQt is a small rectangle depending on the business form of the destination store, it may be detected as the stay position candidate CA. For example, when the destination store set in the mobile phone 200 is a restaurant or a bookstore, the same location may stay for a certain time or longer. Therefore, the store position estimation accuracy can be further improved by changing the detection method of the stay position candidate CA according to the relationship between the size of the estimation target rectangle SQt and the business form of the target store.

B2. Modification 2:
FIG. 19 is an explanatory diagram illustrating an example in which a complex facility is divided into regions at predetermined intervals. In FIG. 19, the complex facility is divided into regions at intervals of L1 substantially parallel to the parallels and L2 substantially parallel to the meridians. In this modification, the stay position candidate CA is extracted differently from the above embodiment, and the control unit 113 extracts the stay position candidate CA by the same method as the above embodiment, and then the position of the divided region (mesh) in the complex facility. A specific mesh is extracted as a stay position candidate CA by weighting according to the area of the mesh or the like. Specifically, the stay position candidate CM00 shown in FIG. 19 extracted by the same method as in the above embodiment overlaps with the mesh CM21 and the mesh CM22. In this case, since the stay position candidate CM00 overlaps with the mesh CM22 in a larger area than the mesh CM21, the mesh CM22 is extracted as the stay position candidate CA. In addition, the method for extracting the stay position candidate CA is not limited to the method in the above-described embodiment and this modification, and can be variously modified. For example, in FIG. 19, both the mesh CM 21 and the mesh CM 22 where the stay position candidates CM 00 overlap may be extracted as the stay position candidates CA.

  Further, as shown in FIG. 19, by dividing the complex facility into regions, the stay position candidate CA can be extracted based on the time spent on a specific mesh. Specifically, probe information including position information in the mobile phone 200 ′ is first collected in the mesh CM 31, and then exits the mesh CM 31 and collects probe information including position information of the mobile phone 200 ′ in a different mesh. Is done. In this case, the control unit 113 can calculate the time that the mobile phone 200 ′ has stayed in the mesh CM 31 based on the number of nodes included in the mesh CM 31.

  FIG. 20 is an explanatory diagram showing an example of the relationship between the stay position candidate CA and the stay time of the mobile phone 200 ′ in the complex facility. FIG. 20 shows the relationship between the position coordinates of the stay position candidate CA and the time during which the mobile phone 200 ′ stays at the stay position candidate CA in the region-divided complex facility shown in FIG. 19. As shown in FIG. 20, when the divided mesh is 2 minutes or longer, the control unit 113 extracts the mesh as a stay position candidate CA. In this modification, unlike the case where the stay position candidate CA is extracted based on the number of nodes included in the estimation target rectangle in the above embodiment, the stay time in the stay position candidate CA is also used for estimating the destination store. A high store position can be estimated.

B3. Modification 3:
As shown in FIG. 2, the control unit 113 of the information collection unit 110 in the server 100 may change the method for extracting the stay position candidate CA based on the facility information stored in advance in the facility information DB 115. . For example, when the business mode of the target store set in the mobile phone 200 is eating and drinking, it is considered that there is little change in the position of the mobile phone 200 in the target store. For this reason, in this modification, the estimation target rectangle setting method and the threshold value to be compared with the number of nodes included in the estimation target rectangle are changed. Thereby, since the store position is estimated using facility information such as the business form of the store stored in advance, it is possible to estimate the store position with higher accuracy.

  Further, in the above embodiment, the position of the target store is estimated from the probe information of the mobile phone 200 in which the target store is set. However, using the probe information of the mobile phone 200 ′ in which the target store is not set, The common area CM may be calculated. Even if the destination store is not set, the mobile phone 200 'may pass through the common area CM. Therefore, in this modified example, more probe information of the mobile phone 200 can be collected and the accuracy of position estimation of the common area CM can be increased. By using these, it is possible to estimate the store position with higher accuracy.

B4. Modification 4:
Moreover, although the said embodiment demonstrated and demonstrated the store in a complex facility as an example, the complex facility in this invention is not restricted to complex facilities, such as shopping center SC, Various deformation | transformation is possible. For example, it may be an office building in which a plurality of offices are occupying, or a building in a station attached to the premises of a train station.

  In the above-described embodiment, the mobile phone 200 receives the position information of the mobile phone 200 measured by the GPS unit 201 and generates probe information. However, the mobile phone 200 is configured by wireless communication such as wireless LAN or mobile communication. The current position may be specified and probe information may be generated. In addition, by measuring the three-dimensional position of the mobile phone 200 by GPS, wireless LAN, or the like, it is possible to know the number of floors where the mobile phone 200 is located in the complex facility. This makes it possible to estimate the store position with higher accuracy in the complex facility.

  In the above embodiment, as shown in step S237 and step S238 in FIG. 4, when the mobile phone 200 arrives at the destination facility, the route guidance of the mobile phone 200 ends. However, the route guidance method is not limited to this, and various modifications are possible. Is possible. For example, route guidance may be performed to the destination store instead of the destination facility. If the location of the destination store has not been estimated, guidance may be provided to the arrival point of the destination facility where the destination store stored in advance is located. Further, when the server 100 performs a route search (step S132 in FIG. 4), it is determined whether or not the position of the target store is estimated, and if the position is estimated, the purpose is Route guidance to the target store, not to the facility, may be performed, and if position estimation is not performed, route guidance to the target facility may be performed.

  In the above embodiment, as shown in step S243 of FIG. 5, the timing of completing the collection of the probe information of the mobile phone 200 is determined based on whether the mobile phone 200 has left the target facility. The collection of probe information may be controlled. For example, after it is determined that the user of the mobile phone 200 has arrived at the destination store, the operation unit 206 of the mobile phone 200 may be operated to end the transmission of the probe information to the server 100. In this modified example, since the collection of probe information is completed when arriving at the destination store, the store location can be estimated with higher accuracy in the complex facility. Further, the server 100 may collect probe information for a predetermined time after arrival at the destination facility and the route guidance is completed, for example, 30 minutes. Since the user of the mobile phone 200 that sets the destination store as the mobile phone 200 can predict that he / she will go to the destination store at an early stage after arriving at the destination facility, the store location can be estimated with higher accuracy.

  Further, in the above embodiment, when the map is displayed on the map in step S176 of FIG. 14, if the position coordinate point of the name display of the complex facility shown in FIG. 3 and the estimated center Pst01 of the store are close, the store However, the relationship between the display position of the complex facility name and the display position of the store name can be variously modified. For example, the display position of the name of the complex facility may be changed by displaying the display position of the store name on the estimated center Pst01 of the store. Alternatively, the estimated store center Pst01 and the store name display position may be stored separately in the facility information DB 115, and the display position may be changed as appropriate according to the scale of the map.

  In addition, among the constituent elements in the above-described embodiment, elements other than the elements described in the independent claims are additional elements, and can be omitted or combined as appropriate.
