  FIG. 2 is a diagram illustrating an example of a route search request transmitted from the user terminal 12 to the facility search server 20 along the route. As shown in FIG. 2, the route search request includes information necessary for searching for a route, such as a departure point, a destination, a latitude / longitude of a waypoint, and priority conditions. The route search request also includes a user ID that is a user identifier. Note that the identifier of the user terminal 12 may be included instead of the user ID.

  FIG. 3 is a diagram illustrating an example of a facility search request transmitted from the user terminal 12 to the facility search server 20 along the route. The facility search request is for searching for a facility along the route to be searched, and includes, for example, a genre code and a name for specifying the facility as shown in FIG. The facility search request also includes a user ID that is an identifier of the user. Similar to the facility search request, the identifier of the user terminal 12 may be included instead of the user ID.

  Returning to FIG. 1, the map server 14 provides map data for displaying a map, and includes a map information storage unit 40 and a map information search unit 42. The map information search unit 42 receives from the user terminal 12 a map acquisition request in which a map center point, range, scale, and the like are set, acquires map data corresponding to the request from the map information storage unit 40, and receives the user terminal. 12 can be transmitted. Note that the map server 14 can be accessed not only from the user terminal 12 but also from other information processing apparatuses such as the facility search server 20 along the route.

  The route search server 16 provides route information indicating a route from the departure point to the destination in response to a search request, and includes a route information storage unit 50 and a route information search unit 52. The route information search unit 52 receives a route search request in which information such as a departure place, destination, and waypoint is set from the facility search server 20 along the route, and receives route information corresponding to the request from the route information storage unit 50. It can be acquired and transmitted to the facility search server 20 along the route.

  FIG. 4 is a diagram illustrating an example of route information transmitted from the route search server 16 to the route along facility search server 20. As shown in FIG. 4, in the route information, in addition to the distance and required time of the searched route, the fee required for the expressway, etc., the latitude / Position information (link position information) such as longitude, shape data including the type of each line, and guidance information for performing guidance such as a right turn or a left turn at an intersection are included. Here, the type included in the shape data indicates the type of line, and examples of the type of automobile road include a general road and a highway.

  Returning to FIG. 1, the facility search server 18 provides facility information indicating a facility (POI: Point of Interest) in response to a facility search request, and includes a facility information storage unit 60 and a facility information search unit 62. Composed. The facility information search unit 62 receives a facility search request in which information such as the name, genre, and mesh code of the facility is set from the facility search server 20 along the route, and receives facility information corresponding to the request from the facility information storage unit 60. It can be acquired and transmitted to the facility search server 20 along the route. Here, the mesh code is an identifier of a mesh area (also simply referred to as “mesh”) obtained by dividing an area on the map into a mesh shape by latitude and longitude.

  FIG. 5 is a diagram illustrating an example of the structure of the facility information storage unit 60. As shown in FIG. 5, the facility information stored in the facility information storage unit 60 includes position information (facility position information), name, address, telephone number, genre code, mesh code, and adjacent mesh code. . Here, the genre code is information for identifying the genre of the facility, such as a convenience store, a restaurant, or a gas station. In the mesh code, the mesh code of the mesh area where the facility exists is set. In the adjacent mesh code, the code of the mesh area adjacent to the mesh area where the facility exists is set. In the adjacent mesh code, codes for all adjacent mesh areas are not set, but codes for mesh areas determined to be within a predetermined threshold distance or time from the facility are set.

  FIG. 6 is a diagram for explaining adjacent mesh regions set in facility information. In FIG. 6, the facility X belongs to the mesh area A. Therefore, the mesh code of the mesh area A is set as the mesh code of the facility information of the facility X. In addition, the facility X is located within a broken-line circle indicating that it is within a predetermined distance from the center of the mesh region B adjacent to the mesh region A. That is, although the facility X is outside the mesh region B, it is determined that it is located near the mesh region B. In this case, the mesh code of the mesh region B is set in the adjacent mesh code of the facility information of the facility X. In addition, although the example which determines an adjacent mesh area | region by the linear distance from the center of a mesh area | region was shown here, the determination method is not restricted to this. For example, the determination may be made based on the distance from the intersection in the mesh region, or may be made based on the moving time by a predetermined moving means. Moreover, you may use the distance which considered the road and the route instead of a linear distance. In addition, a mesh code of a plurality of mesh regions can be set as the adjacent mesh code. Further, the mesh code of the mesh area to which the facility belongs and the mesh code of the adjacent mesh area may be managed by one data item.

  Although FIG. 6 shows a quadrangular mesh area, the shape of the mesh area is not limited to a quadrangular shape. Moreover, it is good also as the area | region which overlaps between adjacent mesh area | regions being provided. In this case, it is possible to determine that a facility located near the boundary of a certain mesh region is also included in a mesh region adjacent to this mesh region. Thereby, similarly to the example of FIG. 6, mesh codes of a plurality of mesh areas can be associated with facility information of one facility.

  FIG. 7 is a diagram illustrating an example of a facility search request transmitted from the facility search server 20 along the route to the facility search server 18. As shown in FIG. 7, the facility search request includes a mesh code, a genre code, and a name. In response to such a facility search request, the facility information search unit 62 of the facility search server 18 searches for facility information that matches the conditions set in the facility search request, and transmits the search result to the facility search server 20 along the route. To do. Specifically, the facility information search unit 62 extracts facility information in which each mesh code set in the facility search request is set as a mesh code of the facility information or an adjacent mesh code, and the genre code and the name match. . Only one of the genre code and the name may be set, or both may not be set. Moreover, it is good also as selecting whether an adjacent mesh area | region is included in search object. The mesh code is structured according to the order of the mesh area, and the facility information in which the mesh code of the lower mesh area is set using the mesh code of the upper mesh area set in the facility search request. Can also be extracted.

  Returning to FIG. 1, the facility search server 20 along the route searches for the route and the facility using the route search server 16 and the facility search server 18 in response to the route search request and the facility search request from the user terminal 12, and the search result. Is transmitted to the user terminal 12, and a route search unit 70, a search route information storage unit 72, a facility search unit 74, a mesh region specifying unit 76, a search facility information storage unit 78, a line specifying unit 80, and a facility information output unit 82 is comprised. In addition, each part which comprises the facility search server 20 along a path | route can be implement | achieved by using storage areas, such as a memory and a memory | storage device, or running the program memorize | stored in memory.

  The route search unit 70 receives a route search request transmitted from the user terminal 12. The route search unit 70 acquires route information from the route search server 16 by transmitting a route search request from the user terminal 12 to the route search server 16. That is, the route search unit 70 acquires route information by indirectly referring to the route information storage unit 50 of the route search server 16. Then, the route search unit 70 stores the acquired route information in association with the user ID included in the route search request in the search route information storage unit 72 and transmits it to the user terminal 12.

  The facility search unit 74 acquires the facility information from the facility search server 18 by generating the facility search request illustrated in FIG. 7 and transmitting it to the facility search server 18 in response to the facility search request from the user terminal 12. . That is, the facility search unit 74 acquires facility information by indirectly referring to the facility information storage unit 60 of the facility search server 18. The facility search unit 74 stores the acquired facility information in the search facility information storage unit 78 in association with the user ID included in the facility search request. The facility search unit 74 acquires route information associated with the user ID included in the facility search request from the search route information storage unit 72, and specifies a mesh code corresponding to the route indicated by the route information. By specifying using the unit 76, the facility search request illustrated in FIG. 7 can be generated.

  The mesh region specifying unit 76 specifies a mesh region on the route based on the route information stored in the search route information storage unit 72, and outputs a mesh code of the specified mesh region. Here, the size of the mesh region may be determined in advance, or may be changed according to a request from the user terminal 12. For example, size information for designating the size of the mesh area may be set in the facility search request transmitted from the user terminal 12. Further, as will be described later, the mesh area specifying unit 76 can change the size of the mesh area in accordance with the number and density of facilities along the searched route and specify the mesh area on the route again. is there.

  FIG. 8 is a diagram for explaining an outline of processing for specifying a mesh region on a route. First, the mesh area specifying unit 76 configures a route based on the route information stored in the search route information storage unit 72 (1). Next, the mesh area specifying unit 76 selects a line between two points constituting the route (2). The mesh area specifying unit 76 creates a rectangle of the selected line (3), and specifies a mesh area including the created rectangle (4). Since the mesh region is defined by a predetermined rule based on latitude / longitude, the mesh region specifying unit 76 may specify the target mesh region based on the latitude / longitude information included in the route information. Is possible. The mesh area specifying unit 76 obtains a mesh area that overlaps the line selected in (2) within the mesh area specified in (4) (5), and leaves only the mesh area that overlaps the line (6). And the mesh area | region on a path | route is specified by performing the process of (2)-(6) about each line which comprises a path | route.

  FIG. 9 is a diagram for explaining a modified example of the process of specifying the mesh region on the route. Here, it is assumed that the processes (1) to (4) shown in FIG. 8 are performed. Thereafter, the mesh area specifying unit 76 creates a buffer for the line selected in (2) (5). Here, the line buffer is an area having a predetermined width including the line, and the width of the buffer can be changed according to a request from the user terminal 12, for example. Then, the mesh area specifying unit 76 obtains a mesh area that at least partially overlaps the buffer created in (5) within the mesh area specified in (4) (6), and selects only the mesh area that overlaps the buffer. Leave (7). And the process of (2)-(7) is performed about each line which comprises a path | route, and the mesh area | region on a path | route is specified. In this way, by creating a line buffer and specifying a mesh region, a mesh region that does not overlap with the line but is close to the line, such as mesh regions X and Y shown in FIG. Is possible.

  FIG. 10 is a diagram for explaining an overview of processing for searching for facilities in the identified mesh area. FIG. 10 shows the mesh region specified by the process shown in FIG. When the mesh region is specified in this way, the facility search unit 74 generates a facility search request in which the mesh code of the specified mesh region is set, and transmits the facility search request to the facility search server 18. Then, the facility search server 18 refers to the facility information storage unit 60 and searches for facility information that matches the conditions set in the facility search request. As described above, when searching for facility information, adjacent mesh codes may be considered. Further, when a plurality of mesh codes are set in the facility information or when adjacent mesh codes are set, if the same facility information is searched repeatedly, the facility search server 18 The facility information can be transmitted to the facility search server 20 along the route after the information is merged. The facility information searched in this way is transmitted from the facility search server 18 to the facility search server 20 along the route.

  Returning to FIG. 1, the line specifying unit 80 (route (link) specifying unit) refers to the searched route information storage unit 72 and the searched facility information storage unit 78, and the line corresponding to each searched facility and the line Identify attributes (route (link) attributes for each facility). Then, the line specifying unit 80 adds information indicating the attribute of the line specified for each facility to the facility information stored in the search facility information storage unit 78. The line attribute is information indicating the type of line (general road / highway, etc.), the distance from the facility to the line, the positional relationship between the facility and the line (left / right), and the like. This will be specifically described with reference to FIG.

  In the example shown in FIG. 11, the route indicated by the searched route information includes line L1 to line L5, and the facility indicated by the searched facility information includes facility P1 to facility P9. The line specifying unit 80 associates each facility with the line having the shortest distance based on the position information of each facility and the position information of each line. The position information of each line is information indicating the position of each line, and in this embodiment, is position information of the start point and end point of the line. For example, as illustrated in FIG. 11, the line specifying unit 80 can specify the line L1 as the line having the closest distance from the facility P1. The other facilities P1 are similarly linked to any of the lines L1 to L5.

  Further, the line specifying unit 80 specifies the attribute of the line associated with each facility. For example, if the line L1 is a route on a general road, the line specifying unit 80 can specify that the type of the line is “general” as the attribute of the line linked to the facility P1. The type of each line can be acquired from the route information. In FIG. 11, if the start point of the line L1 is N1 and the end point is N2, the facility P1 is located on the right side in the traveling direction on the line L1. In this case, the line specifying unit 80 can specify that the facility is located “right” of the line as the attribute of the line linked to the facility P1. The positional relationship between the facilities and the lines can be determined based on the position information of each facility and the position information of each line. Since the distance from the facility to the line is calculated when the line is specified, this result can be used as the line attribute.

  FIG. 12 is a diagram illustrating an example of facility information to which information indicating line attributes is added by the line specifying unit 80. As shown in FIG. 12, information indicating line attributes is added to the facility information of each facility. Although not shown in the example of FIG. 12, information for identifying the associated line may be added to the facility information of each facility.

  Returning to FIG. 1, the facility information output unit 82 transmits the facility information stored in the search facility information storage unit 78 to the user terminal 12 as a search result for the facility search request from the user terminal 12. That is, the facility information output unit 82 outputs the facility information acquired from the facility search server 18 in association with information indicating the link attribute of the link specified for each facility. At this time, the facility information output unit 82 can filter the facility information in consideration of the distance from the route.

  FIG. 13 is a diagram for explaining the outline of the facility information filtering process. Here, it is assumed that the route information and facility information shown in FIG. 10 have been acquired. In this state, the facility information output unit 82 first creates a buffer for the entire line (1). Here, the buffer for the entire line is an area having a predetermined width including the entire line, and the width of the buffer can be changed according to a request from the user terminal 12, for example. Then, the facility information output unit 82 leaves only the facility information of the facility included in the created buffer (2). In this way, by creating a buffer for the entire line and filtering the facility information, it is possible to exclude facilities that are more than a predetermined distance from the route. In the example illustrated in FIG. 13, among the facilities P1 to P9, the facility P2 and the facility P5 are excluded from the output targets because they are outside the buffer.

  14 to 16 are diagrams illustrating examples of screens displayed on the user terminal 12 based on the route information and the facility information received from the facility search server 20 along the route. Here, it is assumed that the facility information after filtering illustrated in FIG. 13 is transmitted to the user terminal 12. As illustrated in FIG. 14, the control unit 32 of the user terminal 12 can display the route information and the facility information acquired from the facility search server 20 along the route on the display unit 36 together with the map. At this time, when the facility information includes a plurality of genres, the control unit 32 can display the genre of each facility information in an identifiable manner. In addition, the control unit 32 can display the type of genre included in the facility information, and can display only the facility information of the genre selected by the user. Further, the control unit 32 can acquire map data necessary for displaying route information and facility information from the map server 14. In addition, it is good also as the facility search server 20 along a route | route acquiring the map data required when displaying route information and facility information from the map server 14, and transmitting to the user terminal 12. FIG.

  And since the information which shows a link attribute is contained in the facility information transmitted to the user terminal 12, it is possible to select the displayed facility by using this information. For example, in the screen shown in FIG. 14, all three of “route left side”, “route right side”, and “high-speed nearest” are selected. In this case, the control unit 32 of the user terminal 12 displays any facility whose line attribute “left / right” value associated with the facility information is “left” or “right”. In addition, the control unit 32 of the user terminal 12 displays any facility whose line attribute “type” value associated with the facility information is “general” or “high-speed”.

  On the screen shown in FIG. 14, when the selection of “route right side” is canceled, the control unit 32 of the user terminal 12 causes the facility whose line attribute “left / right” value associated with the facility information is “right”. Is excluded from the display target. An example of the screen displayed thereby is shown in FIG. As shown in FIG. 15, the facilities P1 and the facilities P4 displayed on the screen of FIG. 14 are excluded from the display targets because they are on the right side of the route.

  In addition, when the selection of “high-speed nearest” is canceled on the screen shown in FIG. 14, the control unit 32 of the user terminal 12 sets the value of the “type” of the line attribute associated with the facility information to “high-speed”. Are excluded from the display target. An example of the screen displayed in this way is shown in FIG. Here, it is assumed that the lines L2 to L4 in the route shown in FIG. 13 are highways. In this case, as shown in FIG. 16, facilities P3, facility P4, facility P6, and facility P7 displayed on the screen of FIG. 14 are excluded from the display target because the associated links are expressways. Has been.

  Thus, since the link attribute is associated with the facility information, the user terminal 12 can select the facility to be displayed according to the link attribute. The screens shown in FIGS. 14 to 16 do not show an interface for selecting the facility to be displayed according to the distance from the link, but the line attributes are similar to the line attributes “left and right” and “distance”. The facility to be displayed may be selectable also by “distance”. Further, in the user terminal 12, for example, by selecting the displayed facility information, it is possible to confirm detailed information on the facility or set the facility as a transit point.

  FIG. 17 is a flowchart illustrating an example of a route search process in the route facility search server 20. The route search unit 70 receives a route search request from the user terminal 12 (S1701). In response to the route search request, the route search unit 70 transmits a route search request to the route search server 16 (S1702), and receives route information from the route search server 16 (S1703). Then, the route search unit 70 adds the user ID set in the route search request to the received route information and stores it in the search route information storage unit 72 (S1704), and transmits the route information to the user terminal 12. (S1705).

  FIG. 18 is a flowchart illustrating an example of a flow of facility search processing in the facility search server 20 along the route. The facility search unit 74 receives a facility search request from the user terminal 12 (S1801). The facility search unit 74 acquires route information corresponding to the user ID set in the facility search request from the search route information storage unit 72 (S1802), and uses the mesh region specifying unit 76 to identify the mesh region on the route. It is specified (S1803). When the mesh region is specified, the facility search unit 74 generates a facility search request in which the mesh code of the specified mesh region is set and transmits it to the facility search server 18 (S1804). Information is received (S1805). The facility search unit 74 adds the user ID set in the facility search request to the received facility information and stores it in the search facility information storage unit 78 (S1806).

  When the facility along the route is searched, the line identifying unit 80 identifies the line having the closest distance for each facility based on the location information included in the route information and the location information included in the facility information. The line attribute of the line is specified (S1807). The line specifying unit 80 adds the line attribute of the specified line to the facility information stored in the search facility information storage unit 78 (S1808).

  When the line attribute is added, the facility information output unit 82 creates a buffer for the entire line constituting the route based on the position information included in the route information, and filters the facility information (S1809). Then, the facility information output unit 82 transmits the facility information extracted by filtering to the user terminal 12 (S1810).

  In addition, when the number and density of searched facilities are less than a predetermined reference value, the mesh area specifying unit 76 can also specify a mesh area on the route using a higher (larger) mesh area. It is. On the other hand, when the number or density of searched facilities is equal to or higher than a predetermined reference value, the mesh area specifying unit 76 may specify a mesh area on the route using a lower (smaller) mesh area. Is possible. When the size of the mesh region is changed in this way, the facility search unit 74 can search for facility information again using the mesh code of the identified mesh region. In addition, the size change of the mesh area may be performed partially rather than the entire route. Note that the size of the buffer at the time of filtering can be changed in accordance with the size change of the mesh region. Further, when the size of the mesh area is partially changed, the buffer for filtering may be partially changed.

  The present embodiment has been described above. In this embodiment, the facility information of the facility along the route is output in association with the attribute of the link specified by the positional relationship between the facility and the route, that is, the link attribute of the facility. Therefore, for example, when the facility information is displayed on the user terminal 12, it is possible to select the facility to be displayed based on the attribute of the link. That is, according to the present embodiment, facility information for enabling display of facility information necessary for the user can be provided.

  Specifically, for example, as shown in FIG. 15, it is possible to display only the facilities on the left side of the route. Similarly, it is possible to display only the facilities on the right side of the route. For example, as shown in FIG. 16, it is also possible to select a facility to be displayed according to the type of link.

  Further, in this embodiment, instead of searching for facilities along the route based on many points on the route, the facility corresponding to the mesh region is searched after specifying the mesh region on the route. . As a result, the number of search processes is reduced, and the processing load when searching for facilities along the route can be reduced.

  Further, according to the present embodiment, it is possible to specify a mesh region on a route by setting a buffer for the route as shown in FIG. Since the mesh area is obtained by dividing the area on the map into a mesh shape, there may be a case where the mesh area does not overlap with the lines constituting the path even though the distance to the path is short. Therefore, by setting a buffer as shown in FIG. 9, it is possible to additionally specify a mesh region that is close to the route. As a result, the facility in the additionally specified mesh area is also searched, and the facility search accuracy can be improved.

  Further, according to the present embodiment, it is possible to filter the retrieved facility information by setting a buffer for the route as shown in FIG. As a result, it is possible to exclude a facility that is within the identified mesh region but has a distance from the route that is equal to or greater than a predetermined distance.

  Note that this embodiment is intended to facilitate understanding of the present invention and is not intended to limit the present invention. The present invention can be changed / improved without departing from the spirit thereof, and the present invention includes equivalents thereof.

  For example, in the present embodiment, the case of searching for a route for an automobile has been described as an example. However, the target route is not limited to this, and an arbitrary route can be targeted. For example, a route by train or bus or a route by foot may be included. Information corresponding to the type of route, such as trains, buses, and sidewalks, can be set as the type of each line in the route information. Thereby, for example, when a facility along the route of walking and train is searched, it is possible to exclude the facility along the train route from the display target.

  Also, for example, in this embodiment, the facility associated with the mesh region is searched after specifying the mesh region on the route, but a large number of points on the route can be obtained without using the mesh region. The facility along the route may be searched as a reference.

  Further, for example, in the present embodiment, the route search request and the facility search request are individually transmitted from the user terminal 12 to the facility search server 20 along the route. However, the search request in which the route search request and the facility search request are combined. May be transmitted from the user terminal 12 to the facility search server 20. In this case, the route along facility search server 20 executes route search and facility search as a series of processes in response to a search request from the user terminal 12, and collects route information and facility information obtained as a result to the user terminal 12. Can be sent.

  Further, for example, in this embodiment, the route search and facility search are performed in the route along facility search server 20, but a system configuration that does not use the route along facility search server 20 may be used. For example, when the user terminal 12 acquires route information from the route search server 16 and the user terminal 12 transmits the route information to the facility search server 18, the facility search server 18 searches for facilities along the route. Also good.

  The configuration of the route along facility search server 20 shown in the present embodiment is an example. For example, some or all of the functions of other servers such as the route search server 16, the facility search server 18, and the map server 14 are included. It may be included in the facility search server 20.
