  The user does not always perform the route search after determining the destination. For example, when traveling, the destination area is decided first, and detailed sightseeing spots are often examined while moving, or are often decided in consideration of time, weather, and the like locally. In this case, in the terminal device of Non-Patent Document 1 that needs to select a tourist spot in advance as a destination, or a general route search device that performs a route search by setting a departure point and a destination, the route search is performed. There is a problem that is difficult.

  Also, in Patent Document 1, when an area different from an administrative area, such as an area introduced in a guidebook, is set as a destination, the destination cannot be set by an address or a telephone number, so route guidance is received. There is a problem that can not be.

  The present invention has been made in view of the above problems, and its purpose is to provide a route search device, a route search system, and a route that can appropriately search for a route to a sightseeing spot without setting a detailed destination. A search method and a route search program are provided.

  According to one aspect of the present invention, the route search system includes information acquisition means, search condition setting means, reference point acquisition means, and route search means. The information acquisition unit acquires area information indicating an area in which an area is set based on position information of a plurality of spots. The search condition setting means receives a search condition setting including a departure place and the area information by a user. The reference point acquisition unit acquires reference point information indicating a reference point included in the area corresponding to the area information set by the user. The route search means generates route information by using a route network information to perform a route search using a reference point indicated by the acquired reference point information from the departure point as a transit point or a destination.

  According to the present invention, the user selects one of the predetermined sightseeing areas, and the route to the reference point in the sightseeing area is searched, so that it is appropriate even without setting a specific destination. You can search for routes to sightseeing spots.

  Embodiments according to the present invention will be specifically described below with reference to the drawings.

(First embodiment)
FIG. 1 is a schematic block diagram of a route search system according to the first embodiment of the present invention. The route search system includes a terminal device 1 and a server (route search device) 2. As illustrated, the terminal device 1 communicates with the server 2 via the network 3.

  The terminal device 1 is used by a user and is, for example, a mobile electronic device such as a mobile phone, a smartphone or a tablet terminal, or a stationary electronic device such as a car navigation device. The network 3 may be either a wired line or a wireless line, and the type and form of the line are not limited.

  The terminal device 1 includes a communication unit 11 and a control unit 12.

  The communication unit 11 is an interface that transmits and receives information between the control unit 12 and the server 2 via the network 3.

  The control unit 12 includes an operation input unit 121, a display unit 122, a search condition setting unit 123, a search request transmission unit 124, and an information reception unit 125.

  The operation input unit 121 is an interface for a user to input an operation to the terminal device 1, and is, for example, a keyboard, a touch pad, a dial button, or the like in a mobile electronic device, or a touch panel or a microphone in a stationary electronic device.

  The display unit 122 displays a screen for setting search conditions, search results, and the like, and is a liquid crystal display, for example. In addition to the display unit 122, a voice output unit that outputs voice for route guidance may be provided.

  The search condition setting unit 123 sets a search condition by receiving conditions such as information regarding a departure place, a destination, and time via the operation input unit 121 from the user. In the present embodiment, area information to be described later can also be selected as a search condition.

  The search request transmission unit 124 transmits a search request including a search condition to the server 2 and requests the server 2 to perform a route search based on the search condition.

  The information receiving unit 125 receives information transmitted from the server such as route information and map information from the communication unit 11 via the network 3 and displays the information on the display unit 122.

  On the other hand, the server 2 includes a communication unit 21, a storage unit 22, and a control unit 23.

  The communication unit 21 is an interface that transmits and receives information to and from the terminal device 1 via the network 3.

  The storage unit 22 stores a map database 221 including map information, a route network database 222 including route network information, and an area database 223 including area information.

  The map information includes map data and facility information related to facilities associated with the map data. The map data indicates maps of vehicle roads such as general roads, toll roads, and expressways. The route network information is information that defines a traffic network such as a railroad or a bus or a road network. Information on the transportation network includes route information, timetable information, toll information, etc. of transportation facilities. The information on the road network is expressed by a combination of node data that is a node on the road network expression such as an intersection and link data that is a road section between nodes.

  FIG. 2 is a diagram illustrating an example of the structure of the area database 223 that is one of the features of the present embodiment. The area database 223 includes area information and reference points.

  The area information is not an administrative area but a name indicating an area set based on position information of a plurality of spots, and the position is associated with map information. In the following, a description will be given taking a sightseeing area including a plurality of sightseeing spots as an example. Tourist areas include, for example, a tourist area (“Ueno / Asakusa area”, etc.) that combines multiple areas for the convenience of tourists, and a wide area tourist area that includes multiple municipalities (“Shonan area in southern Kanagawa Prefecture”) ”,“ Toho area ”in the eastern part of Kagawa Prefecture), and sightseeing areas representing a specific area (such as“ Minami area ”around Osaka Namba Station). The area information may be an area name that has been used for a long time, or may be created based on a tourist guidebook or the like.

  The reference point is a point determined based on the relationship between spots included in the area, particularly the positional relationship, and is, for example, an arbitrary point included in the sightseeing area indicated by the area information. One or more reference points are defined for each area information. The reference point is, for example, a point where a representative facility or sightseeing spot in the area is located, a point where restaurants or accommodation facilities are densely located, a geographical center point, a point where a main station is located, or the like.

  The reference point is preferably a point that is easy to move to another spot in consideration of road conditions and transportation. Thereby, as will be described later, the area is first set as a destination or waypoint and moved to a reference point in the area, and then it can be efficiently moved to a spot designated as a visit destination.

  1 includes an information acquisition unit 231, a search request reception unit 232, a reference point acquisition unit 233, a route search unit 234, and an information transmission unit 235.

  The information acquisition unit 231 is an interface with the storage unit 22 that accesses the storage unit 22 and acquires information from various databases.

  The search request receiving unit 232 receives a search request including a search condition from the terminal device 1.

  The reference point acquisition unit 233 acquires the reference point corresponding to the selected area information from the area database 223 via the information acquisition unit 231 when the search condition includes area information.

  In response to the search request, the route search unit 234 performs a route search based on the route network information stored in the storage unit 22 and the search conditions, and generates route information indicating the route.

  The information transmission unit 235 transmits information such as map information, area information, and route information from the communication unit 21 to the information reception unit 125 of the terminal device 1 via the network 3.

  FIG. 3 is a sequence diagram illustrating an example of a processing operation of the route search system according to the first embodiment of the present invention. In FIG. 3, the user does not define a clear destination, but keeps in mind that the user selects a destination from the area information presented by the server 2.

  First, the information acquisition unit 231 of the server 2 acquires map information within a predetermined range and area information included in the range from the map database 221 and the area database 223 of the storage unit 22, respectively. And the information transmission part 235 transmits these to the terminal device 1 via the network 3 from the communication part 21 (step S31). The predetermined range is, for example, a rectangular range around the current position of the terminal device 1 or an arbitrary position set by the user. The user may set the scale of the map information in advance and adjust the range of the displayed map information. As the scale, for example, one of a plurality of predetermined scales is selected by the user.

  When the information receiving unit 125 of the terminal device 1 receives map information and area information from the communication unit 11 via the network 3 (step S11), the display unit 122 displays map information and an area selection button (step S12).

  FIG. 4 is a diagram illustrating an example of a screen including map information and area selection buttons displayed on the display unit 122. The display unit 122 in the figure is centered on Saitama Prefecture and displays map information over a wide area with a relatively small scale. In addition to the map information, an area selection button is displayed at the end of the display unit 122.

  When the user selects an area selection button via the operation input unit 121, the display unit 122 displays the area information superimposed on the map information (step S13).

  FIG. 5 is a diagram illustrating an example of a screen including map information and area information displayed on the display unit 122. In the figure, “Mizukami / Okutone / Sarugahara area”, “Maebashi / Takasaki area”, “Higashimatsuyama / forest park area” and “Saitama city / Kawaguchi / Toda area” are displayed as area information. Further, the area information may be further narrowed down so that only area information in an arbitrary prefecture is displayed.

  When the user selects the area information displayed via the operation input unit 121, the selected area information is set in the search condition setting unit 123 as a search condition (step S14). Further, the user sets a departure place in the search condition setting unit 123 via the operation input unit 121 (step S15). Note that the current position of the terminal device 1 may be automatically acquired and set as a departure place, or the departure place may be set prior to selection of area information. In addition, conditions such as departure or arrival time and waypoints may be further set.

  Subsequently, the search request transmission unit 124 transmits a search request including a search condition including the selected area information and the set departure place from the communication unit 11 to the server 2 via the network 3 (step S16).

  When the search request receiving unit 232 of the server 2 receives a search request from the communication unit 21 via the network 3 (step S32), the reference point acquisition unit 233 refers to the area database 223 of FIG. 2 via the information acquisition unit 231. Then, a reference point corresponding to the area information included in the search request is acquired (step S33). When a plurality of reference points corresponding to the area information are determined, the reference point acquisition unit 233 acquires one of them. At this time, time information such as the season and time of departure, and attribute information such as the age and sex of the user registered in advance in the server 2 may be taken into consideration. For example, in autumn, the autumn leaves spot is used as a reference point, or the beach is used as a reference point for young users, while the hot spring is used as a reference point for elderly users.

  Next, the route search unit 234 acquires route network information from the storage unit 22 via the information acquisition unit 231, and using this, the reference point acquired by the reference point acquisition unit 233 from the departure point set by the user. A route search with the point as the destination is performed to generate route information (step S34). Then, the information transmission unit 235 transmits route information from the communication unit 21 to the terminal device 1 via the network 3 (step S35).

  When the information reception unit 125 of the terminal device 1 receives the route information from the communication unit 11 via the network 3 (step S17), the display unit 122 displays the route information indicating the route from the departure place to the above-described reference point ( Step S18).

  As described above, in the first embodiment, the area information is presented to the user from the server 2, and the user selects a desired area from the presented area information. Then, a route whose destination is the reference point of the area selected from the departure point is searched. Therefore, even when the user does not clearly determine the destination and determines only a tourist area different from the administrative division, route information to the tourist area can be presented to the user.

  As shown in FIG. 6, the area information may be defined hierarchically so that the area information can be selected according to the scale of the map information displayed on the display unit 122. For example, the area information can have a hierarchical structure according to the area size or a hierarchical structure according to the number of spots. In the case of a hierarchical structure corresponding to the size of the tourist area, for example, “Harajuku area” as upper area information indicating a wide tourist area, and “Takeshita street area as lower area information indicating a narrow tourist area in this area, for example. ”" Ura Harajuku area ". If you want to display a wide area map with a reduced map information scale, select the “Harajuku area”. If you want to display a detailed map with a larger scale, select the “Takeshita street area” according to the position of the displayed map information. ”Or“ Ura Harajuku area ”. Thus, the convenience of the user is improved by linking the scale and the area information area.

  In step S33 of the present embodiment, an example in which the reference point is included in the area database 223 in advance is shown. However, the reference point is not necessarily included in the area database 223. For example, each time an area is selected, the reference point acquisition unit 233 may calculate and acquire a reference point corresponding to the area in consideration of a user attribute, season, and the like. Alternatively, the reference point acquisition unit 233 may acquire the reference point from an external information distribution server.

(Second Embodiment)
In the first embodiment described above, the route search is performed using the selected area as the destination. On the other hand, in the second embodiment described below, a route search is performed using a selected area as a transit point.

  The schematic configuration of the route search system is the same as in FIG.

  FIG. 7 is a sequence diagram illustrating an example of a processing operation of the route search system according to the second embodiment of the present invention. In the present embodiment, it is assumed that the user has already set a departure place and a destination, and selects a sightseeing area as the waypoint. In the following description, differences from the first embodiment will be mainly described.

  First, the user sets a departure point and a destination in the search condition setting unit 123 via the operation input unit 121 (step S51). Subsequently, the search request transmission unit 124 transmits a search request including a search condition including the departure place and the destination from the communication unit 11 to the server 2 via the network 3 (step S52).

  When the search request receiving unit 232 of the server 2 receives a search request from the communication unit 21 via the network 3 (step S71), the route search unit 234 searches for a route from the departure point to the destination and generates route information. (Step S72). Then, the information transmission unit 235 transmits area information from the communication unit 21 to the terminal device 1 via the network 3 in addition to the route information and the map information around the route (step S73). Here, the information transmission unit 235 is an area information that indicates an area that is likely to stop from the departure point to the destination or an area around the destination, more specifically, for example, a predetermined range from a route from the departure point to the destination. It is desirable to transmit the area information within.

  When the information receiving unit 125 of the terminal device 1 receives route information or the like from the communication unit 11 via the network 3 (step S53), the display unit 122 displays map information, route information, and an area selection button. (Step S54). When the user selects the area selection button via the operation input unit 121, the display unit 122 displays the area information superimposed on the map information (step S55).

  FIG. 8 is a diagram illustrating an example of a screen including map information, route information, and area information displayed on the display unit 122. The point that the searched route information is also displayed is different from FIG. 5, and it can be seen from this screen how far each area is from the route.

  When the user selects the area information displayed via the operation input unit 121, the selected area information is set in the search condition setting unit 123 as a search condition (step S56). Subsequently, the search request transmission unit 124 sends a search request including a search condition including the selected area information as a transit point to the network 3 from the communication unit 11 in addition to the departure point and destination already set in step S51. To the server 2 (step S57).

  When the search request reception unit 232 of the server 2 receives a search request from the communication unit 21 via the network 3 (step S74), the reference point acquisition unit 233 receives the information acquisition unit 231 through the information acquisition unit 231 as in the first embodiment. By referring to the area database 223, a reference point corresponding to the area information included in the search request is acquired (step S75). Next, the route search unit 234 again performs a route search from the set departure point to the destination using the acquired reference point as a transit point, and generates route information (step S76). Then, the information transmission unit 235 transmits route information from the communication unit 21 to the terminal device 1 via the network 3 (step S77).

  When the information receiving unit 125 of the terminal device 1 receives the route information from the communication unit 11 via the network 3 (step S58), the display unit 122 uses the reference point of the tourist area selected in step S56 as a transit point. The route information from the destination to the departure point is displayed (step S59).

  As described above, in the second embodiment, the waypoint of the route from the preset departure point to the destination is selected from the area information presented from the server 2. Therefore, the user can easily select a sightseeing area to stop by on the route.

(Third embodiment)
In the first and second embodiments described above, the route to the reference point in the area selected by the user is searched. On the other hand, in the third embodiment described below, after searching for a route to the reference point, a spot in the sightseeing area is further presented to the user, and the route to the spot is searched again.

  FIG. 9 is a schematic block diagram of a route search system according to the third embodiment of the present invention. In FIG. 9, the same components as those in FIG. 1 are denoted by the same reference numerals, and different points will be mainly described below.

  FIG. 10 is a diagram showing an example of the configuration of the area database 223a stored in the storage unit 22a of the server 2a in FIG. As shown in the figure, the area database 223a is included in the sightseeing area indicated by the area information, and further includes spot information indicating spots to be visited and the number of times of selection. The spots are, for example, sightseeing spots, theme parks, restaurants, accommodation facilities, and the like, and their positions are associated with map information. The number of times of selection is the number of times that the spot information has been selected by the user so far, and is incremented each time it is selected. The number of selections is not limited to a specific user, and may be the number of selections by a plurality of users who use the route search system.

  In addition, it is good also considering the point of a typical spot in a spot, or the point where spots are crowded as a reference point.

  FIG. 10 shows an example in which one or a plurality of spot information included in the sightseeing area is included in the area database 223a based on the sightseeing area indicated by the area information. However, the attribute of each spot information may include area information indicating a sightseeing area where the spot is included.

  Further, the control unit 23a of the server 2a in FIG. 9 further includes a spot extraction unit 236. When receiving the spot selection request from the terminal device 1, the spot extraction unit 236 refers to the area database 223 a via the information acquisition unit 231 and extracts spot information corresponding to the area information.

  FIG. 11 is a sequence diagram illustrating an example of a processing operation of the route search system according to the third embodiment. Steps S11 to S17 and S31 to S35 are the same as those in the first embodiment shown in FIG.

  When the information receiving unit 125 of the terminal device 1 receives the route information from the communication unit 11 via the network 3, the display unit 122 displays a screen including a spot selection request button in addition to the route information from the departure point to the reference point. (Step S18 '). At this time, not only the route information but also the route guidance to the destination (reference point) may be started.

  FIG. 12 is a diagram illustrating an example of a screen including route information displayed on the display unit 122 and a spot selection request button. A spot selection button is further displayed at the end of the display unit 122. This figure is an example when “Higashimatsuyama / forest park area” is selected in step S14. When the user selects the spot selection request button via the operation input unit 121, a spot selection request is transmitted to the server 2 (step S19).

  When the search request reception unit 232 of the server 2 receives the spot selection request (step S36), the spot extraction unit 236 refers to the area database 223 of FIG. 10 via the information acquisition unit 231, and the sightseeing area selected in step S14 The spot information contained in is extracted (step S37). The spot extracting unit 236 may extract all spot information in the sightseeing area, or may extract only some spots in consideration of user attribute information and departure time information. Further, a predetermined number of pieces of spot information may be extracted in descending order of the number of selections in the area database 223 of FIG. Thereby, a spot with high popularity and evaluation can be preferentially presented to the user. When area information is included as an attribute of spot information, spot information including the sightseeing area selected in step S14 may be extracted as an attribute. The information transmission unit 235 transmits the extracted spot information to the terminal device 1 (step S38).

  When the information receiving unit 125 of the terminal device 1 receives the extracted spot information (step S20), the display unit 122 displays the spot information superimposed on the map information (step S21).

  FIG. 13 is a diagram illustrating an example of a screen including route information and spot information displayed on the display unit 122. In the drawing, “spot A” and “spot B” are displayed as spot information. A list may be displayed in order of increasing selection number, or spot information may be displayed in association with a position on map information.

  When the user selects one or more of the spot information displayed via the operation input unit 121, the selected spot information is set in the search condition setting unit 123 as a search condition (step S22). Subsequently, the search request transmission unit 124 transmits the selected spot information to the server 2 from the communication unit 11 via the network 3 (step S23).

  When the search request receiving unit 232 of the server 2 receives the selected spot information (step S39), the number of selections in FIG. Then, the route search unit 234 uses the route network information to perform again the route search using the spot indicated by the selected spot information as the destination from the departure point set by the user, and the route obtained by the search. Is generated (step S40). Then, the information transmission unit 235 transmits the route information from the communication unit 21 to the terminal device 1 via the network 3 (Step S41).

  When the information receiving unit 125 of the terminal device 1 receives the route information from the communication unit 11 (step S24), the display unit 122 displays the route information (step S25).

  Thus, in 3rd Embodiment, after a user selects a sightseeing area, the spot information contained in the sightseeing area is further shown to a user. Therefore, the user can set a destination in more detail and simply and can search for a route to the destination.

  In the present embodiment, the spot selected by the user is set as the destination, but the selected spot may be set as the waypoint as in the second embodiment.

  Further, in the area database 223a of FIG. 10, the number of selections is stored for each spot, but in addition to (or instead of) the number of selections, the evaluation of the user who uses this route search system is stored, and the spot extraction unit 236 is stored. May extract spots in consideration of evaluation. In addition, the area database 223a stores the category of the spot (eating / playing, etc.) and the theme (historic walking / healing trip / location tour, etc.), and the spot extracting unit 236 determines whether the spot is extracted by the user. Depending on the type setting, spots may be extracted as appropriate. Moreover, you may extract the spot which can go within predetermined time.

  Furthermore, in the present embodiment, a spot is determined for each area information, but a model course may be determined for each area information and stored in the area database 223a. In this case, the control unit 23a has a model course extraction unit (not shown). The model course is determined by a plurality of spots in the same tourist area and the order of their visit. Then, the user may request the server 2a to search for a model course instead of selecting a spot in step S22. As a result, a route including the model course is searched, and a recommended course can be presented to a person who has not decided a destination.

  A plurality of model courses may be defined for each area, a plurality of model courses may be presented to the user, and one of them may be selected by the user, and the user's attribute information and departure time information may be selected. In consideration, one model course may be presented from the server 2.

  Moreover, although the example of a screen (FIG. 4 etc.) in each embodiment has shown the example in which area information and spot information are displayed as a text, you may display a photograph and an image | video. This makes it easier to understand the atmosphere and appearance of area information and spot information.

  Furthermore, in each embodiment, information on a period (season) that is a highlight may be added to the area information and spot information. Then, highlight area information and spot information may be highlighted based on the time information at the time of departure.

  The present invention can also work with a plurality of guidebooks. That is, the contents of guidebooks each having its own area database are stored in the storage unit of the server 2 in advance, and when the user selects one of the guidebooks, the area database of the selected guidebook is used. A route search may be performed.

  Further, a guidebook display button is provided in the terminal device 1, and when area information or spot information is selected, a configuration in which it is possible to request the display unit 122 to display a page containing the corresponding page or detailed information is displayed. Good.

  Furthermore, the spots included in one area do not necessarily have to be related.

  1 and FIG. 9 is an example, and at least a part of the configuration requirements in the servers 2 and 2a may be in the terminal device 1, or conversely, at least one of the configuration requirements in the terminal device 1. The part may be in the server 2 or 2a. For example, the storage unit 22 (or 22a) and the control unit 23 (or 23a) in the server 2 are provided in the terminal device 1 to configure a route search device that can search for a route only by the terminal device 1 without communication. May be. In this case, the search request transmission unit 124, the search request reception unit 232, and the like may be omitted as appropriate according to the configuration. Further, the server 2 may be configured using a plurality of devices. For example, only the storage unit 22 may be provided in a separate device.

  At least a part of the route search system described in the above-described embodiment may be configured by hardware or software. When configured by software, a program for realizing at least a part of the functions of the route search system may be stored in a recording medium such as a flexible disk or a CD-ROM, and read and executed by a computer.
