・ Operation of the map display system:
The map display system 10 provides a route guidance service to the user of the mobile terminal 200. A user of the route guidance service operates the mobile terminal 200 to set a departure place and a destination. The user may further set a waypoint that passes along the way from the departure point to the destination. The departure point may be the current position measured by the GPS receiver 201.

  The mobile terminal 200 transmits to the information providing server 100 coordinate information (latitude and longitude) that specifies the departure point, the destination, and if necessary, the waypoint. Based on the received information, the information providing server 100 collates / searches the route database 106 and, if necessary, the map database 156 of the map server 150, determines a guide route, and generates guide route information representing the guide route. .

  The guide route is a route from the departure point to the destination extracted from the traffic routes registered in the route database 106, and the guide route information is the coordinate information of a plurality of nodes ND that specify the guide route. This information describes the order on the route so that it can be specified. That is, a line connecting a plurality of nodes ND with line segments in order represents a guide route. Here, the guidance route information includes coordinate information of all the nodes ND on the guidance route. The guide route information further includes node attribute data of a plurality of nodes ND that specify the guide route and turn determination data that indicates whether or not each node ND that specifies the guide route is a turn point. Here, the “turned place” is an intersection that requires a turn such as a right turn or a left turn when the user (mobile terminal 200) travels on the guide route. The configuration for generating the guide route information by the information providing server 100 corresponds to the “guide route information generating unit” described in the application example 1. The guide route corresponds to the “route” in the description of application example 1.

  The information providing server 100 transmits the generated guide route information to the mobile terminal 200. The mobile terminal 200 requests and acquires map image data in a necessary range from the map server 150 based on the guide route information (here, in particular, coordinate information of the node ND included in the guide route information), and acquires the map image data and the guide Route guidance is executed using the route information.

  FIG. 3 is a conceptual diagram illustrating an example of a guidance route. In the example shown in FIG. 3, a guide route RT from the vicinity of the lower left end to the vicinity of the upper right end is set. The guide route RT shown in FIG. 3 passes through the hatched areas of the rectangular area MS set in the area database 108 in the order of the numbers added together with the hatching.

  FIG. 4 is a conceptual diagram showing an example of a screen displayed on the display panel when route guidance is executed. In the present embodiment, a map image display area MW and an information display area IW are displayed on the display panel 202 when performing route guidance. A map image is displayed in the map image display area MW. In the map image, the guide route RT is displayed in a color different from other roads, for example, in such a manner that it can be distinguished from other routes (roads and the like). In the map image display area MW, a current position display PP1 representing the current position of the user is superimposed and displayed based on current position information measured at predetermined intervals using the GPS receiver 201. A route guidance service is provided by displaying the map image display area MW. On the other hand, in this embodiment, various information related to the guide route RT is displayed in the information display area IW. The displayed contents will be described later.

・ Route information display processing:

  FIG. 5 is a flowchart showing the flow of the route information display process. When the route information display process is started, the main control unit 210 of the mobile terminal 200 acquires current position information representing the current position using the GPS receiver 201 (step S110). Here, the acquired current position information may be shared with the route guidance processing performed in parallel. The processing in step S110 corresponds to the “specific position information acquisition unit” described in application example 1. When the current position information is acquired, the main control unit 210 of the mobile terminal 200 transmits the current position information to the information providing server 100 of the server system 1000 (step S120).

  In the server system 1000, when the information providing server 100 receives the current position information (step S210), the control unit 104 of the information providing server 100 includes a guide route from the departure place to the destination based on the current position information. Then, a plurality of nodes to be displayed in the information display area IW are selected, and node attribute data of each selected node is acquired (step S220). Here, the plurality of nodes to be displayed are a predetermined number of bent nodes (hereinafter referred to as “first predetermined number”) close to the current position specified by the current position information. In other words, the predetermined condition to be displayed satisfies both that the node ND is i) a bent node and ii) is included in the first predetermined number of nodes close to the current position specified by the current position information. That is.

  A “bent node” is a node corresponding to a bent part. Further, the first predetermined number of bending nodes close to the current position are, for example, three forward bending nodes and two rear bending nodes. The three forward turn nodes are the turn nodes that pass first, second, and third when the guide route is traced forward (destination side) from the current position. The two rear turn nodes are the first and second turn nodes when the guide route is traced from the current position to the rear (starting side). Note that the number of forward turn nodes is not limited to the above three, and may be other numerical values. Further, the number of backward bending nodes is not limited to the above two, and may be other numerical values. Further, the number of backward bending nodes may be zero. That is, only a predetermined number of forward bent nodes may be displayed.

  In the route guidance processing performed in parallel, node attribute data of a plurality of nodes ND that specify the guidance route RT and bending determination data indicating whether or not the portion is a bending portion are stored as guidance route information. Therefore, in step S220, specifically, by extracting the node attribute data for the three forward turn nodes and the two back turn nodes from the stored guide route information, Get node attribute data.

  In this embodiment, the nodes close to the current position to be displayed are limited to the nodes corresponding to the bent portions as described above, but instead, all the nodes including the nodes not corresponding to the bent portions are included. It may be a node. Moreover, it is good also as what includes the node applicable to a bending location, and the node which shows a main intersection. The main intersection is an intersection included in a main road having a road width equal to or greater than a predetermined value. Further, it may include other nodes such as intersections that are confusing even if going straight.

  Next, the control unit 104 of the information providing server 100 determines a rectangular region MS to be provided with region feature information (hereinafter also simply referred to as “feature information”) to the mobile terminal 200 based on the current position information ( Step S230). Here, the current position indicated by the current position information in any of the sections between two adjacent nodes (hereinafter referred to as “bent node section”) in the plurality of nodes determined to be the display target in step S220. A rectangular area MS that is to be provided with the feature information of a plurality of rectangular areas MS set in the area database 108 and included in the bent node section determined to include the current position. It is determined.

  FIG. 6 is an explanatory diagram showing a case where a rectangular area MS to be provided with feature information is determined. In FIG. 6A, a thick line indicates the guide route GL. The guide route GL includes the current position Pn. As shown in FIG. 6A, the current position PN is included in a bent node section between a point P1 indicated by the first bent node and a point P2 indicated by the second bent node. The bent node section between P1 and P2 includes a first rectangular area MS1 and a second rectangular area MS2, as shown. Therefore, in the case shown in FIG. 6A, the first rectangular area MS1 and the second rectangular area MS2 are determined as the rectangular areas to be provided with feature information.

  On the other hand, in the case shown in FIG. 6B, the current position PN on the guide route GL is a bent node section between the point P1 indicated by the first bent node and the point P3 indicated by the third bent node. include. The bent node section between P1 and P3 includes only the first rectangular area MS1 as shown in the figure. Therefore, in the case shown in FIG. 6B, only the first rectangular area MS1 is determined as a rectangular area where the feature information is to be provided.

  Returning to FIG. 5, after executing step S230, the control unit 104 acquires the region attribute information Z3 and the sub region attribute information associated with the rectangular region MS determined in step S230 from the region database 108 (step S240). ). The acquired area attribute information Z3 and sub-area attribute information are the characteristic information of the rectangular area MS determined in step S230. As illustrated in FIG. 6A, when the plurality of rectangular areas MS are determined as the rectangular areas to be provided with the feature information, the feature information of each of the plurality of rectangular areas MS1 and MS2 is acquired, As illustrated in FIG. 6B, when one rectangular area MS1 is determined as a rectangular area that should provide feature information, the feature information of the one rectangular area MS1 is acquired.

  After execution of step S240, the control unit 104 determines each node attribute data for the plurality of nodes acquired in step S220 and one or more acquired in step S240 (hereinafter, this number is referred to as a “second predetermined number”). Each feature information of the rectangular area MS of the call is transmitted to the portable terminal 200 (step S250). Each node attribute data is transmitted in such a manner that the order on the guide route for each node ND specified by each node attribute data can be recognized. For example, each node attribute data is transmitted in the form of one file (node attribute file).

  FIG. 7 is an explanatory diagram conceptually illustrating an example of the node attribute file 50 transmitted from the control unit 104 of the information providing server 100 to the mobile terminal 200. In the node attribute file 50 shown in FIG. 7, each node attribute data is associated with the numbers -2, -1, +1, +2, and +3. The node attribute data associated with the number -2 is information about the second node on the rear side (departure side) from the current position, and the node attribute data associated with the number -1 is behind the current position. The node attribute data associated with the number +1 is information about the first node from the current position to the front side (destination side), and is the number +2. The associated node attribute data is information about the second node ahead of the current position, and the node attribute data associated with the number +3 is information about the third node ahead of the current position. is there.

  The number makes it possible to recognize the order on the guide route for each node ND specified by each node attribute data, and further, 2 associated with both numbers by a number of -1 and a number of +1. It is possible to recognize that there is a current position between nodes for one node attribute data.

  Returning to FIG. 5, the feature information of the predetermined number of rectangular areas MS transmitted in step S <b> 250 can be recognized in the order on the guide route.

  When the mobile terminal 200 receives the node attribute data and the feature information of the rectangular area MS from the information providing server 100 (step S130), the main control unit 210 of the mobile terminal 200 describes the path describing each node attribute data. A guide graphic and a feature information graphic describing each feature information (region attribute information Z3 and sub-region attribute information) are displayed (step S140). The route guidance graphic and the route guidance graphic are displayed in the information display area IW shown in FIG.

  FIG. 8 is an explanatory diagram showing an example of display in the information display area IW. In the information display area IW, a first predetermined number (five) of rectangular route guide figures M1 to M5 are displayed. Node attribute data is described in each of the route guidance figures M1 to M5. The arrangement order of the node attribute data is based on the order on the guide route for each node ND specified by each node attribute data. That is, the route guidance figures M1 to M5 include node attribute data with numbers of −2, −1, +1, +2, and +3 in the node attribute file 50 illustrated in FIG. 7, that is, “XX intersection” and “◇◇ intersection”. ”,“ XX intersection ”,“ ΔΔ intersection ”,“ □□ intersection ”are described in this order.

  Furthermore, a second predetermined number of rectangular features are provided between the route guidance figures M2 and M3 in which both the node attribute data of the number -1 and the number +1 in the node attribute file 50 illustrated in FIG. 7 are described. An information graphic MX is displayed. Feature information is described in each of the feature information figures MX. In the case of the example of FIG. 6B, one feature information graphic MX in which feature information of one rectangular area MS1 that is the second predetermined number is described is displayed. That is, as shown in FIG. 8, the feature information graphic MX in which the feature information “It is a region with many Italian restaurants” including the node attribute data “Many Italian restaurants” is displayed. Here, only the region attribute information Z3 is described as the feature information in the feature information graphic MX. Instead, in addition to the region attribute information Z3, sub-regions such as “delicious”, “pizza”, and “pasta” The attribute information Z31 to Z33 can also be described together.

  Note that the feature information graphic MX is displayed larger than the route guidance graphics M1 to M5. Further, the current position display PP2 is superimposed on the feature information graphic MX. This is because the rectangular area MS corresponding to the feature information described in the feature information graphic MX includes the current position.

  The route guidance figures M1 to M5 and the feature information figure MX are connected by an arrow AR. As a result, the feature information graphic MX is displayed in association with the sequence of the route guidance graphics M1 to M5. As a result, the user can display the feature information graphic in a predetermined section (a section including the current position in the present embodiment) between the respective turn nodes corresponding to the node attribute data described in the route guidance patterns M1 to M5. It can be easily recognized that the region (specifically, the rectangular region MS) corresponding to the feature information described in MX is included.

  Further, the feature information graphic MX includes a button (user interface) SB for receiving a search processing execution instruction from the user. When the user operates the user interface SB to instruct search processing, search processing related to the feature information indicated in the feature information graphic MX is executed. In the example shown in FIG. 8, the feature information shown in the feature information graphic MX is “It is an area where there are many Italian restaurants”. For example, when a search processing instruction is accepted, the current position is included. As a search result of Italian restaurants existing in the rectangular area MS, a list of Italian restaurants is displayed in the information display area IW.

  Specifically, when the main control unit 210 of the mobile terminal 200 receives an instruction for search processing, the main control unit 210 transmits the search instruction to the information providing server 100. In response to the search instruction, the control unit 104 of the information providing server 100 searches the facility database 107 to extract information on the Italian restaurant existing in the rectangular area MS including the current position, and extracts the extracted information. To the portable terminal 200. The main control unit 210 of the mobile terminal 200 displays the returned information in the information display area IW, so that, for example, a list of Italian restaurants is displayed.

  Below the information display area IW, buttons BT1 and BT2 for turning on / off the display of characteristic area guidance, that is, the display of the characteristic information graphic MX are displayed. When the user instructs to select the [ON] button BT1, the feature information graphic MX is displayed together with the route guidance graphics M1 to M5 as described above. On the other hand, when the user instructs to select the [OFF] button BT2, only the route guidance graphics M1 to M5 are displayed without displaying the feature information graphic MX (the start graphic M0 in FIG. 12A is removed). State).

  FIG. 9 is an explanatory diagram illustrating another example of display in the information display area. This example shows only the main part of the display of the information display area, and corresponds to the portion between the route guidance graphic M2 and the route guidance graphic M3 in FIG. This example is a case where two rectangular regions MS are acquired as rectangular regions to which feature information is to be provided in step S240, that is, in the case of the example in FIG. 6A.

  As shown in the figure, there are many “Italian restaurants” in the first rectangular area MS1 between the route guidance graphic M2 described as “◇◇ intersection” and the route guidance graphic M3 described as “xx intersection”. ”And the second feature information graphic MX2 describing the feature information“ Many Chinese restaurants ”in the second rectangular area MS2 are displayed. . The first feature information graphic MX1 and the second feature information graphic MX2 are displayed in the order in which the front-rear relationship in the guide route of the first and second rectangular areas MS1 and MS2 can be recognized. In other words, the second feature information graphic for the second rectangular area MS2 is closer to the route guidance graphic M2 in which the first feature information graphic MX1 for the first rectangular area MS1 is described as “◇◇ intersection”. MX2 is displayed on the side close to the route guidance figure M3 in which “XX intersection” is described. As described above, the number of feature information graphics acquired as the rectangular area to be provided with the feature information in step S240 is displayed between the route guide graphics M2 and M3.

  Returning to FIG. When the route guidance graphic and the feature information graphic are displayed, the main control unit 210 of the mobile terminal 200 determines whether or not a predetermined time has passed (step S150). When the predetermined time has not elapsed (step S150: NO), the main control unit 210 waits for the elapse of the predetermined time. When a certain time has elapsed (step S150: YES), main controller 210 returns to step S110 and repeats the above-described processing.

  As a result, the contents of the route guidance graphic and the feature information graphic displayed in the information display area IW correspond to the movement of the current position of the user (mobile terminal 200), that is, the position by the GPS receiver 201 of the mobile terminal 200. It is updated according to the positioning result. For example, when the current position of the user moves from the state shown in FIG. 8 into a bent node section between the node described in the route guidance graphic M3 and the node described in the route guidance graphic M4, the route guidance shown in FIG. The contents of the figure M3 are moved to the position of the route guidance figure M2 in FIG. 8, and the contents shown in the feature information figure MX in FIG. 8 are the feature information about the rectangular area MS included in the moved bent node section. Switch to That is, as the user moves along the guidance route RT, the contents of the route guidance graphic and the feature information graphic displayed in the information display area IW are updated with an image scrolling in the direction of the arrow in FIG. The feature information graphic shows the feature information about the rectangular area MS included in the bent node section including the current position.

  According to the embodiment described above, the route guidance figures M1 to M5 indicating the turning points (folding nodes) in the guide route RT are displayed on the display unit in the order in which they match the order on the guide route RT. It can be easily recognized that the area corresponding to the feature information described in the feature information graphic MX is included in the bent node section including the position. As a result, for example, it is possible to search for a place to detour or a place to take a break in accordance with the characteristics of the area, so that it is possible to provide a route guidance service with higher added value to the user.

B. Variations:
・ First modification:
In the above embodiment, when a plurality of rectangular areas MS exist in the bent node section including the current position, a plurality of feature information figures MX corresponding to each rectangular area are displayed. Thus, only one feature information graphic may be displayed.

  FIG. 10 is an explanatory diagram illustrating an example of display of the information display area in the first modification. This example shows only the main part of the display of the information display area, and corresponds to the portion between the route guidance graphic M2 and the route guidance graphic M3 in FIG. As shown in FIG. 10, one feature information graphic MXX is displayed between the route guidance graphic M2 described as “◇◇ intersection” and the route guidance graphic M3 described as “xx intersection”. In the feature information figure MXX, feature information of two rectangular areas MS1 and MS2 (corresponding to the example of FIG. 6A) selected as the rectangular areas to be provided with the feature information is described together. That is, the feature information of the first rectangular area MS1 that “there are many Italian restaurants” and the feature information of the second rectangular area MS2 that “there are many Chinese restaurants” are described together.

  Specifically, a character string “Italian cuisine” corresponding to the feature information of the first rectangular region MS1 and a character string “Chinese cuisine” corresponding to the feature information of the second rectangular region MS2 are feature information graphics. It is described in MXX. Note that the feature information graphic MXX includes buttons (user interfaces) SB1 and SB2 that individually correspond to both feature information. When the user operates the user interfaces SB1 and SB2 to instruct search processing, search processing related to the corresponding feature information is executed.

  According to the illustration of FIG. 10, the character string “Italian cuisine” corresponding to the feature information of the first rectangular area MS1 corresponds to the feature information of the second rectangular area MS2 on the lower side (route guidance graphic M2 side). The character string “Chinese cuisine” is displayed on the upper side (route guidance graphic M3 side), so that the context in the guidance route of the first and second rectangular regions MS1 and MS2 can be recognized. It is. Alternatively, the order of the above description may be irrelevant to the context of the corresponding rectangular area in the guide route.

  Furthermore, it is good also as a structure which registers a user's preference beforehand and determines the order of description of the feature information in the said feature information figure MXX in consideration of the said user's preference. In addition, the history of past user interface operations on feature information figures is accumulated, and feature information that is highly likely to be selected by the user from the accumulated result is displayed on the upper side (side that is easy to see). It is good also as composition to do.

  According to the first modified example described above, a route guidance service with higher added value can be provided in the same manner as in the embodiment. In particular, in this modified example, when a plurality of rectangular areas to which feature information is to be provided are selected, a compact display is possible.

・ Second modification:
In the above embodiment, only the feature information graphic MX for the rectangular area MS existing in the bent node section including the current position (specific position) is displayed, but instead, it exists in the bent node section. Although not shown, a feature information graphic for a rectangular region MS located nearby may also be displayed. An example of these will be described as a second modification with reference to FIG.

  FIG. 11 is an explanatory diagram showing an example of display in the information display area IWX of the second modification. As shown in the figure, in the information display area IWX of the second modified example, the same content as the information displayed in the information display area IW of the above-described embodiment is displayed. , NMX2 is displayed. In the peripheral feature information figure NMX1 displayed on the left side of the feature information figure MX, feature information about the rectangular area MS located on the left side in the traveling direction with respect to the rectangular area MS existing in the bent node section including the specific position. It has been described. In the peripheral feature information figure NMX2 displayed on the right side of the feature information figure MX, feature information about the rectangular area MS located on the right side in the traveling direction with respect to the rectangular area MS existing in the bent node section including the specific position. It has been described.

  According to the second modified example described above, it is possible to know the feature information of the surrounding area away from the guidance route, and to provide a route guidance service with higher added value. In the second modification, when there is not enough feature information to be displayed on the feature information graphic MX, only the peripheral feature information graphics NMX1 and NMX2 may be displayed without displaying the feature information graphic MX. The peripheral feature information figures NMX1 and NMX2 can also be said to be displayed in association with the route guidance figures M1 to M5.

・ Third modification:
In the above-described embodiment, the feature information graphic MX is displayed larger than the route guidance graphics M1 to M5, so that the feature information is easily noticeable. Instead, the feature information graphic MX is replaced with the route guidance graphics M1 to M1. The feature information graphic may be displayed in a color different from that of the route guidance graphic with the same size as M5. As a result, the feature information can be made conspicuous without enlarging the display area. Further, the feature information graphic MX may be configured to be larger than the route guidance graphics M1 to M5 and displayed in a color different from the route guidance graphics, and according to this configuration, the feature information may be made more conspicuous. it can. Furthermore, the feature information graphic MX may be smaller than the route guidance graphics M1 to M5 and displayed in a color different from the route guidance graphics.

In the above embodiment, the predetermined area that is the target of the feature information graphic MX is the predetermined area that is included in the bent node section that includes the current position. It may be a predetermined area included in the next (turned) turn node section on the guide route. According to this configuration, it is possible to know the feature information of the area ahead of the current position. In addition, it is good also as a 2nd bending node area instead of the following (1st) bending node area. A predetermined area including a point ahead by a predetermined distance (for example, 500 m) from the current position on the guide route may be the target of the feature information graphic MX. In short, a predetermined area determined based on the current position can be the target of the feature information graphic MX.

-5th modification:
In the above-described embodiment, the predetermined area to be the target of the feature information graphic MX is selected based on the current position. However, instead of this, the selection may be made based on the position indicated by the user. . This example will be described as a fifth modification with reference to FIG.
