(Step S204), the first route data and the map data are read from the buffer BF, and the map represented by the map data and the first route represented by the first route data are appropriately displayed (step S204). Step S206).

  Next, the CPU 211 selects a region of interest to be displayed on the display panel 202 using the region information included in the first route information and the first route data), and guides the region of interest and the region of interest. Guidance information is displayed on the display panel 202 (step S208). In the first embodiment, the CPU 211 selects all candidate attention areas represented by the area information received from the route search server 100 as attention areas. Note that the CPU 211 may simply display the characteristic data and feature data of the attention area extracted from the area information as the guidance information in the display of the attention area and the guidance information, or the characteristic data and feature data of the attention area. May be used to generate and display guidance information in a form including buttons and various guidance messages that can be selected.

  Next, the CPU 211 determines whether to set a feature as a transit point (step S210). Specifically, the CPU 211 displays the details of the attention area on the display panel 202 according to the user's operation, and when the user searches and browses the feature details (that is, when the feature details are displayed on the screen). ) Is displayed on the screen for allowing the user to determine whether the feature searched by the user is to be used as a transit point, and if the user selects via the feature searched by the user (step S210: YES) Then, the feature selected by the user is set as a stop feature, that is, a transit point (step S212). In the setting of waypoints, without letting the user individually select features, for example, a screen is displayed to allow the user to determine whether or not to search for a second route that passes through the area of interest. If the user selects to search for the second route, the user may select a feature and set the selected region as a transit point. Further, in selecting the waypoint, the map may be moved to display the area area, and it may be determined whether or not the feature is set as the waypoint according to whether or not the feature is selected. In the setting of waypoints, if there is a region of interest outside the first route, the feature is determined after the user determines whether to search for the second route before viewing the feature details. You may be able to browse and select.

  The CPU 211 generates a second route search request including a search condition including a departure point, a destination, and a waypoint, and transmits the request to the route search server 100 (step S214). The CPU 211 obtains second route information including second route data representing the second route searched for by the route search server 100 and area information of an area at least partially included in a predetermined range of the second route. The received second route and guidance information are displayed on the display panel 202 (step S218).

  The CPU 211 determines whether to set a plurality of features as transit points, that is, whether to set another feature as a transit point in addition to the features set as transit points in step S210 (step S220). If it is determined that the selected feature is to be selected as the transit point (step S220: YES), the process is repeated from step S212 to set another feature as the transit point.

  If the CPU 211 determines that the feature is not set as a transit point (step S210: NO) and determines that the plurality of features are not set as the transit point, in other words, only one feature is selected. If it is set as a waypoint (step S220: NO), the process is terminated.

A4-2. Sample screen:
With reference to FIG. 10 and FIG. 11, the example of a map display screen of the mobile terminal 200 will be described. FIGS. 10 and 11 are explanatory diagrams illustrating screen transitions during route search of the mobile terminal 200 in the first embodiment. In FIGS. 10 and 11, the description of the map represented by the map data is omitted for the sake of simplicity. 10 and 11 show a state in which the display panel 202 is directed sideways.

  FIG. 10A shows an example of a screen during the first route search. On the screen WD, the departure point SP, the destination EP, the first route RT1, the attention areas 322, 324, 325 and the guidance information MSG1 are displayed. When any attention area (attention area 322 in FIG. 10) is selected by the user via the key input unit 205 (area selection means), the screen shown in FIG. 10A is displayed. The guidance information MSG1 is a message for guiding the selected attention area, and is generated using the area information stored in the buffer BF. On the screen WD, for example, as shown in FIG. 10A, the area of the attention area 322 is displayed on the map, and guidance information MSG1 for guiding the attention area 322 is displayed. In the guidance information MSG1, in addition to the characteristics of the region of interest (“gourmet”), selection means (for searching / instructing feature data representing a specific feature from feature data of a plurality of features included in the region) The “investigate store” button in FIG. 10A) is included.

  When the “search shop” button is selected by the user on the screen WD shown in FIG. 10A, the CPU 211 of the mobile terminal 200 displays the screen WD shown in FIG. Specifically, the CPU 211 extracts the genre of the feature included in the attention area 322 from the feature data stored in the buffer BF, and generates and displays the guidance information MSG2 including the selection button.

  In the screen WD shown in FIG. 10B, for example, when “Japanese food” is selected by the user, the CPU 211 of the mobile terminal 200 displays the screen WD shown in FIG. Specifically, the CPU 211 extracts the name of the feature classified in the selected genre from the features included in the attention area, generates the guidance information MSG3, and displays it. At this time, it may be displayed as a “recommended store list” in the guidance information MSG3.

  In the screen WD shown in FIG. 10C, for example, when a feature with the feature name “BBB” is selected by the user, the CPU 211 of the mobile terminal 200 pays attention as shown in FIG. Of the features included in the region 323, guide information MSG4 including the name, address, telephone number, etc. of the selected feature is displayed, and the route is re-searched through the selected store at the bottom of the screen. Guidance information MSG5 for allowing the user to select whether to do is displayed.

  When “Yes” is selected by the user on the screen WD shown in FIG. 11A, the CPU 211 of the mobile terminal 200 determines the feature selected by the user as a transit point, and sets the departure point SP. From the destination to the destination EP, a search request for the second route via the feature selected as the waypoint is transmitted to the route search server 100. In the first embodiment, the route search module 121 also functions as a route feature determination unit that determines the feature selected by the user and the MSG 5 that prompts the selection of the feature as a route feature. When the CPU 211 receives the search result of the second route, as shown in FIG. 11B, the CPU 211 designates the second route RT2 represented by the second route data and the via feature as shown in the screen WD. The guidance information MSG6 representing the feature “BBB” is displayed on the display panel 202. Furthermore, areas 322, 323, and 325 at least partially included in a predetermined range including the second route RT2 (corresponding to the candidate attention area determination range 310) are displayed on the screen WD. In FIG. 11B, for convenience of explanation, the first route RT1 is also shown. However, the first route RT1 may be hidden when the second route RT2 is displayed.

  According to the guidance information providing apparatus of the first embodiment described above, not only the area through which the first route RT1 passes, but also the region outside the first route RT1 but in the vicinity of the first route RT1. Can be presented. Therefore, since the user can easily obtain information on areas where it is easy to stop by when moving from the departure place to the destination, it is possible to effectively use time such as stopping by when there is enough time or when there is traffic, User convenience can be improved.

  In addition, according to the guidance information providing apparatus of the first embodiment, only the attention area in which a part of the area is included in the candidate attention area determination range is set as the guidance target. Therefore, it is possible to present an area where the user can drop in without making a great detour.

  Moreover, according to the guidance information providing apparatus of the first embodiment, various patterns of routes can be easily searched based on the guidance information. Therefore, the user can flexibly select the route from the departure place to the destination, so that convenience for the user can be improved.

B. Second embodiment:
In the first example, all the areas overlapping with the candidate attention area determination range 310 are determined as display targets. In the second embodiment, only when the first route does not pass through the area, all the areas overlapping with the candidate attention area determination range 310 are displayed. The system configuration in the second embodiment is the same as that in the first embodiment. However, in the second embodiment, when the first route passes through the area, the route search module 221 determines that the corresponding area is the attention area, and whether or not other areas are included in the candidate attention area determination range 310. Do not make any judgments. In the following embodiments, an area included in the candidate attention area determination range 310 is referred to as a “candidate attention area”.

  FIG. 12 is a flowchart for explaining the attention area selection processing in the second embodiment. This corresponds to the processing in step S208 of FIG. The CPU 211 determines whether there is a candidate attention area through which the first route passes by using the region information included in the route information and the first route data (step S330). When there is a candidate attention area through which the first route passes (step S330: YES), the CPU 211 selects the corresponding candidate attention area as the attention area (step S332). When the first route does not pass through the candidate attention area (step S330: NO), the CPU 211 selects all candidate attention areas as attention areas (step S334).

  According to the guidance information providing apparatus of the second embodiment, an area outside the route can be guided as the attention area only when there is no attention area in the middle of the route. Therefore, since the user can select a desired route from routes that pass through various regions outside the recommended route from the starting point to the destination, the convenience for the user can be improved.

  Further, according to the guidance information providing apparatus of the second embodiment, when the first route passes through the area, the guidance information of the area outside the route among the candidate attention areas is not displayed on the display unit. It is suitable for a user who thinks that guidance of an attention area that is not located on one route is unnecessary.

C. Third Example:
In the first example, all the regions including at least a part of the candidate attention region determination range are determined as the attention regions. In the third embodiment, when a highway is included in the first route, a region near a predetermined interchange is not selected as a region of interest for a region located near the highway on the first route. The predetermined interchange includes an entry / exit interchange recommended in the first route data, an interchange one ahead of the recommended ride interchange, and an interchange immediately before the recommended exit interchange. The predetermined interchange is not limited to the one described here, and an interchange desired by a user or a provider can be set. In the third embodiment, the system configuration is the same as that of the first embodiment. In the third embodiment, when the first route includes an expressway, the route search module 221 performs a predetermined interchange for a candidate attention area near the expressway among the areas included in the candidate attention area determination range. Do not select nearby candidate attention areas as attention areas. In the third embodiment, the “highway” includes a toll / free road provided with an interchange capable of getting on and off.

C1. Attention area selection processing:
FIG. 13 is a flowchart illustrating attention area selection processing in the third embodiment. This corresponds to the processing details of step S208 in FIG.

  The CPU 211 determines whether an expressway is included in the first route using the first route data stored in the buffer BF (step S500). When the highway is included in the first route (step S500: YES), the CPU 211 determines whether the candidate attention area is located in the vicinity of the highway of the first route (including the region overlapping the highway). Is determined (step S502). When the candidate attention area is in the vicinity of the expressway of the first route (step S502: YES), the CPU 211 selects a candidate attention area in the vicinity of the predetermined interchange among the candidate attention areas as the attention area (step S504). That is, in the third example, the CPU 211 does not determine a candidate attention area near the interchange other than the predetermined interchange among the candidate attention areas near the expressway included in the first route as the attention area. Of the candidate attention areas, candidate attention areas that are not located in the vicinity of the expressway are selected as attention areas.

  If the highway is not included in the first route (step S500: NO) and if all of the candidate attention areas are not located near the highway of the first route (step S502: NO), the CPU 211 is the candidate attention area. Are selected as attention areas (step S506).

  FIG. 14 is an explanatory diagram schematically illustrating a region of interest in the third embodiment. In FIG. 14, the detailed description of the map 300a is omitted for the sake of clarity. The route RT3 represents the first route represented by the first route data in the third embodiment. In the route RT3, the road HW indicated by the alternate long and short dash line represents a highway, and the interchanges IC1 to IC6 represent interchanges. Inter IC 1 represents a ride interchange recommended by the first route for getting on the expressway, and Inter IC 5 represents a descending interchange recommended by the first route for getting off the expressway. The candidate attention areas 351 to 355 represent areas existing in the attention area specification 310a that is a predetermined range including the route RT3 in the map 300a. The candidate attention area determination range 310a represents a range up to a position away from the route RT3 by a predetermined distance (for example, 5 km).

  The CPU 211 determines whether or not the areas 351, 354, and 355 in the vicinity of the expressway among the candidate attention areas 351 to 355 included in the candidate attention area determination range 310a are to be attention areas. That is, the CPU 211 has the interchange IC1 that is the recommended interchange based on the first route data among the interchanges IC1 to IC6 representing the interchange included in the first route data, and the next interchange of the inter IC1 with respect to the traveling direction. IC2 which is the IC2, the IC5 which is the descending interchange recommended by the first route data, and the area located in the vicinity of the four interchanges of the interIC5 which is the interchange immediately before the inter IC5 with respect to the traveling direction select. Specifically, the CPU 211 calculates the distance between each of the inter IC1, IC2, IC4, and IC5 and the center point of each candidate attention area, and the candidate attention areas 351 and 355 whose distances are less than or equal to a predetermined area are the attention areas. The candidate attention area 354 is not selected as the attention area. Note that the CPU 211 calculates the distance between each of the inter IC1, IC2, IC4, and IC5 and a predetermined predetermined feature in each candidate attention area, and selects the candidate attention area whose distance is equal to or less than the predetermined attention area. You may choose as

  Of the regions overlapping with the candidate attention region determination range 310a, the region 352 located in the IC6 that is the interchange ahead of the recommended descending interchange IC5 may not be displayed. Continuing to drive on the highway beyond the recommended descending interchange IC5 is considered to be less operational. Therefore, this makes it possible to hide areas that are considered unnecessary.

  As a result, as shown in FIG. 14B, regions 351, 353, and 355 are selected as attention regions and displayed on the display panel 202.

  According to the guidance information providing apparatus of the third embodiment described above, when the searched route includes an expressway, the area near the expressway is recommended for a ride interchange or a recommended ride interchange for the route. Only an area that is at least partially included in a predetermined range including four interchanges, one of which is the descending interchange recommended by the route and the interchange immediately before the descending interchange, can be displayed. In general, if a searched route includes an expressway, even if there is an area in the vicinity of the expressway, once you get on the expressway, you will rarely get off the expressway at an interchange away from the recommended descending interchange . If you get off at an interchange far from the recommended descending interchange, you will have to get on the highway again to get to the destination, which is costly. Therefore, according to the guidance information providing apparatus of the third embodiment, for a user heading to a destination on a route including a highway in the recommended route, an area that is easy to stop is displayed, and an area that is difficult to stop is not displayed. Can be configured. Therefore, it is possible to omit the display of areas that are highly likely to be unnecessary for the user, and to improve the convenience for the user.

D. Variations:
In the first to third embodiments, the mobile terminal as the guidance information providing device exchanges information with the route search server as the route search device and provides the guidance information. For example, the guidance information providing device May perform route search and route information acquisition. In this case, it is good also as the following aspects.

A guidance information provision method executed by a guidance information provision system that provides a route from a departure place to a destination,

Notification control means for executing control for notifying the route and the guidance information by the notification means;
A guidance information providing device comprising:

  In order to obtain route information, the guidance information providing device has map data, and based on this, the route search and the region information are obtained, and the route search and the region information are obtained by referring to the map data of other devices. A mode of acquiring a route search result and area information by causing a route search to be executed by another device is also included.

  According to the above-described modification, route search and guidance information can be displayed without exchanging information with the route search device, which is preferable. Moreover, you may provide with the computer program which functions a computer as such a guidance information provision apparatus.

-In the third embodiment, it is determined that the area near the interchange just before the getting-on / off interchange, the one ahead of the getting-on / off interchange, and the area near the interchange, but two, three, etc. before and after the getting-on / off interchange, An interchange that is a standard for determining the area to be displayed may be set flexibly.

In the third embodiment, an area located in the vicinity of the interchange on the expressway is targeted for display, but instead of the expressway, transportation such as a train, a bus, an airplane, Similarly, when using a ship, the area can be narrowed down and displayed. In other words, if transportation is included in the recommended route, only the area near the recommended boarding / exiting station or bus stop is displayed, and information on the area near the recommended boarding / exiting point or near the bus stop is not displayed. You may comprise as follows. For example, when there is a stop point such as a train, but the route includes transportation that passes without stopping at that point, the area near the pass point is included in the candidate attention area determination range 310a. Even if it is, it is good also as not selecting as an attention area. In addition, for example, the user may set the presence or absence of a commuter pass in advance, select an area including an ascending / descending point in a commuter pass section as an attention area, and use it as a guidance target.

In the first embodiment, the feature selected by the user is determined as the via feature, but for example, the via feature in the area may be defined in advance. For example, in the case where there are a plurality of features in the area in addition to the feature existing in the center of the region or one point of the largest road in the region, all of them may be used as the via features, The center of gravity of the feature may be defined as the via feature. Alternatively, a rank may be set in advance for the feature, and one of the features having the highest rank may be defined as the via feature. In this way, the user can acquire a route passing through the area simply by selecting the area, and can save the user from having to specify the via feature.

The regional characteristics are not limited to those described in the first to third embodiments, but may include gender, age, etc., such as “for women” and “for teens”. For example, if it is an area where beauty salons and esthetic shops are gathered, it may be simply “reputed beauty salon area”, “area for women in their 20s and 50s”, “beauty area”, or the like. In this case, by having the user's behavior pattern or the user's personal information input in advance by the user, various types of guidance information can be provided to the user's mobile terminal with a simple system configuration.

In the first embodiment, all types of areas are displayed, but only predetermined types of areas may be displayed. In this case, for example, an area to be displayed as an area may be set by the user in advance, or may be selected by the user in the course of route search processing. In this way, it is possible to suppress complication of the screen due to the display of a large number of area information.

The mobile terminal as the guidance information providing device further includes a determination unit that determines whether the first route passes through at least one area, and the determination unit determines that the first route does not pass through the region. Then, the attention area may be determined. In this way, when there is no attention area on the first route, it can be determined whether there is an attention area outside the route. Therefore, when there is an attention area through which the first route passes, it is not necessary to perform a process of selecting an area other than the attention area as the attention area, so that the processing load of the map device can be reduced.

In the first embodiment, the route search server 100 includes, in the route information, regional information of a region that includes at least a part in the candidate attention region determination range. For example, at least a part of the candidate attention region determination range includes The route information may include not only the included region but also the region information of the region included in the map including the searched route. In this way, the mobile terminal is not included in the predetermined range (candidate attention area specifying range) including the first route, but the mobile terminal stores information on the region included in the predetermined range including the second route. Can be easily displayed on the display. Therefore, the user can easily check the guidance information in the vicinity of the second route, and the convenience can be improved.
