Further, “the head of a section” means a point that reaches the first in the section when moving along the route.

  FIG. 4 is a diagram illustrating an example of an image displayed on the display panel 202 in step S420 of FIG. In FIG. 4, the route R0 including the sections S11, S12, and S21 starting from the current position PP represented by an arrow-shaped icon and displayed on the map is displayed. Since the current position PP is on the ground (the first floor), the section S11 is a section that passes through the second floor, and therefore is displayed narrower than the other sections S12 and S21 that are located on the ground in the same manner as the current position. And since section S12 is a walk section, since section S21 is a section which should get on a railroad, S12 and S21 are displayed with a different color. Here, the section S12 is displayed in brown, and the section S21 is displayed in orange. A boarding station mark Msr, which is a red circle, is displayed at the connection point Pc where the end of the section S12 and the beginning of the section S21 are connected.

The “current position” when displaying the route in step S420 is the current position when the current position information is acquired (see step S410). Therefore, when the user moves after the current position information is acquired, the “current position” when displaying the route may be a position different from the actual current position.

  Here, the connection point Pc is on the same floor as the current position PP (the ground, ie, the first floor). However, even when the connection point is on a different level (for example, the second floor) from the current position, the boarding station mark is displayed in the same size and color as when the connection point is on the same ground as the current position.

  By setting it as such an aspect, a user operates the fixed mark (red circle) displayed at the connection point of the section currently displayed with a different color, and sees the timetable in the point (station). The mark can be manipulated in anticipation of possible. Therefore, the user can easily display and view the timetable information of the transportation means in the section restricted by the timetable from the state in which the route is displayed on the screen. The display of the timetable will be described later. Furthermore, in this embodiment, the display content is reminded to the user by the display by a fixed color. For this reason, the display of the route does not become complicated as compared with the case where a part of the displayed information and the summary are displayed on the screen in advance.

  The station mark is displayed in a color (red) different from the preceding and following sections (brown and orange). For this reason, it is difficult for the user to overlook the station mark displayed superimposed on the display of the map image and various information. Therefore, according to this route guidance system, it is possible to effectively notify the user that the section restricted by the timetable starts from there.

  In addition, the mark which is a red circle is displayed not only at the station where the vehicle of the transportation system operated along the timetable is to be boarded but also at the station where the transfer is to be performed in the route. A mark displayed at a station where a transfer is to be performed is referred to as a “transfer station mark” in order to distinguish it from a transfer station mark. Further, when calling the transfer station mark and the transfer station mark without distinction, they are called “station marks”.

  In step S425 of FIG. 3, main control unit 210 of mobile phone 200 determines whether or not the station mark has been operated. For example, if the station mark is tapped using the touch panel 206a, or the cursor is moved to the station mark using the cursor key 206b and clicked, the determination result in step S425 is Yes, and the process Advances to step S430. On the other hand, if such an operation has not been performed, the process proceeds to step S495.

  In step S430, the display of the boarding information created based on the information regarding the transportation means used from the point where the station mark is displayed is displayed. More specifically, the main control unit 210 of the mobile phone 200 uses the timetable server 170 to obtain information on the position of the first connection point that is ahead of the current position on the route and information on the current time. Then, the main control unit 210 acquires information on the timetable at the boarding station at the connection point after the current time from the timetable server 170. Then, the main control unit 210 displays the timetable of the boarding station on the display panel 202.

  FIG. 5 is an example of an image displayed on the display panel 202 of the mobile phone 200 in step S430 of FIG. In step S430 in FIG. 3, the departure time Ttd of a predetermined number of trains near the estimated arrival time of the means of transportation used from the point where the station mark is displayed, the destination Tte, whether it is an express or express train, In addition, for the first train, the timetable information display Tt1 including the mark Ttf indicating the first train is displayed.

  Further, tabs T11 to T13 are displayed on the display panel 202. When the tab T11 is designated, timetable information for weekdays (Monday to Friday) is displayed on the display panel 202. When the tab T12 is designated, the timetable information for Saturday is displayed on the display panel 202. When the tab T13 is designated, timetable information on Sundays and holidays is displayed on the display panel 202. In the example of FIG. 5, timetable information for weekdays (Monday to Friday) is displayed on the display panel 202. The display panel 202 also shows a button Bc for deleting the display of the timetable information in addition to the display of the boarding information.

  In step S435 in FIG. 3, it is determined whether or not a button for deleting the timetable display has been pressed. More specifically, the main control unit 210 of the mobile phone 200 determines whether or not the “close” button Bc displayed on the display panel 202 has been tapped or clicked. If the “close” button Bc is tapped or clicked, the process proceeds to step S440. If the “close” button Bc is not tapped or clicked, the process returns to step S430, and the timetable information as the boarding information is continuously displayed.

  In step S440, the main control unit 210 of the mobile phone 200 deletes the timetable information from the display panel 202 and returns to the state where the current position and route are displayed on the map image (see FIG. 4).

  In step S495, the main control unit 210 of the mobile phone 200 determines whether or not the current position acquired in step S410 is within a predetermined distance from the destination. When the current position is within a predetermined distance from the destination, the main control unit 210 ends the route guidance (step S400 in FIG. 2). If the current position is not within a predetermined distance from the destination, the process returns to step S410.

  FIG. 6 is a diagram showing another example of the image displayed on the display panel 202 in step S420 of FIG. In FIG. 6, a route R0 including sections S21, S22, and S23 is displayed superimposed on the map. The section S23 is a section that uses a railroad on a different route from the sections S21 and S22 so far. The starting point of the section S23 corresponds to the transfer station St. A transfer station mark Mst, which is a red circle, is displayed at the start point of the section S23. The display of the transfer station mark Mst is the same as the display of the transfer station mark Msr.

  FIG. 7 is a diagram illustrating another example of an image displayed on the display panel 202 of the mobile phone 200 in step S430 in FIG. 3 when the transfer station mark Mst is tapped. In step S430 in FIG. 3, as described above, the departure time of a predetermined number of trains from the estimated arrival time of the means of transportation used from the point where the station mark is displayed (that is, the transfer station St), and the destination In addition, it is distinguished whether it is a limited express, an express train or a stop at each station, and if it is the first train, a timetable display Tt2 including a mark indicating the first train is displayed. The functions of the tabs T11 to T13 displayed in the example of FIG. 7 are as described in the example of FIG.

  By setting it as such an aspect, the user can see the timetable in the point (station) by operating a fixed mark (red circle) also about a transfer station. Therefore, the user can easily display the timetable information of the transportation means in the section restricted by the timetable from the state where the route is displayed on the screen. Since the user is reminded of the display content by color, the display of the route is not complicated compared to the case where a part of the displayed information and the summary are displayed on the screen in advance.

  Note that the mobile phone 200 in the present embodiment corresponds to a “route display device” in “means for solving the problems”. The display panel 202 corresponds to a “display unit”. The command input unit 206 corresponds to an “input unit”. The main control unit 210 of the mobile phone 200 corresponds to a “control unit”. The sections S21, S22, and S23 correspond to the “first type section”. The section S11 corresponds to a “second type section”. The boarding station mark Msr corresponds to a “mark”. The GPS unit 201 and the communication unit 205 (telephone communication unit 205a and LAN communication unit 205b) correspond to a “current position acquisition unit”.

B. Second embodiment:
In the second embodiment, a predetermined process is performed after step S440 in FIG. 3 and after the determination of No in step S425 and before step S495.
Other points of the second embodiment are the same as those of the first embodiment.

  FIG. 8 is a flowchart showing processing performed after step S440 of FIG. 3 and after determination of No in step S425 and before step S495. In step S455, the main control unit 210 of the mobile phone 200 is operated according to (i) the end of the second type section to be moved without using the transportation means operated according to the timetable, and the timetable. A range of a predetermined distance from the station (boarding station) at the connection point where the head of the first type section to be moved using means of transportation is connected (for example, a radius of 500 m centering on the station at the connection point) (Ii) Whether the current position is located within a predetermined distance range (for example, a circle with a radius of 500 m centering on the transfer station) from the station (transfer station) where the transfer means is to be transferred Determine whether or not. If the determination result is No, the process proceeds to step S495 in FIG. If the determination result is Yes, the process proceeds to step S460 in FIG.

  In step S460, the main control unit 210 of the mobile phone 200 displays on the display panel 202 a transfer guide as a travel table including the boarding time and the boarding time of the transportation means in the first type section.

  FIG. 9 is a diagram illustrating an example of an image displayed on the display panel 202 in step S460 of FIG. In FIG. 9, among the routes from the current position to the destination, the boarding station (here Shinagawa station), transfer station (here Tokyo station), and exit station (here Korakuen station) of the section using the railway, The itinerary table Rm displayed together with the boarding time and the getting-off time at each station is displayed. In the itinerary table Rm in FIG. 9, for example, a boarding station display Dp11 is associated with a boarding time display Dt11d, a classification of express or express or each station stop, and a display DI12 indicating the destination. . A display Dp12 indicating the departure time, a display Dt12d indicating the departure time, a display D23 indicating whether the train is a limited express, an express train or a stop at each station, and a destination DI23 are displayed in association with the transfer station display Dp12. The display Dt13a of the getting-off time is displayed in association with the display Dp13 of the getting-off station. In addition to the display of the transfer guidance, the display panel 202 also shows a button Bc for deleting the transfer guidance display.

  In this manner, when the user is receiving route guidance (S400 in FIG. 2), the user automatically gets close to the station where the use of the transportation means restricted by the timetable should start. Information on the time to get on can be obtained.

  In step S465 of FIG. 8, it is determined whether or not a button for deleting the transfer guidance display has been pressed. More specifically, the main control unit 210 of the mobile phone 200 determines whether or not the “close” button Bc displayed on the display panel 202 has been tapped or clicked. If the “close” button Bc has not been tapped or clicked, the process returns to step S460, and subsequently, a transfer guide as a itinerary is displayed. When the “close” button Bc is tapped or clicked, the process proceeds to step S495 in FIG. The processing after step S495 is the same as in the first embodiment.

C. Variations:
C1. Modification 1:
In the above embodiment, the communication unit 205 includes a telephone communication unit 205a as a functional unit that communicates with the outside via a mobile phone communication network, and a LAN communication unit as a functional unit that communicates with the outside through a wireless LAN. 205b (see FIG. 1). That is, a mobile phone communication network and a wireless LAN are cited as “wireless communication” using radio waves transmitted from a base station. However, the route guidance apparatus can also include a receiving unit of another aspect that can transmit and receive radio waves to and from a base station for wireless communication. For example, the route guidance device may include a receiving unit that can receive Bluetooth (trademark) radio waves. The route guidance device may be configured to be able to specify the current position based on the intensity of Bluetooth (trademark) radio waves transmitted from three or more devices and the location information of the transmission point. it can.

C2. Modification 2:
In the above embodiment, the main control unit 210 of the mobile phone 200 as the route guidance device is based on the radio wave intensity of four or more wireless LAN base stations or four or more mobile phone base stations. Estimate the position. However, the control unit of the route guidance apparatus can also estimate the current position based on the radio wave intensity of the three base stations.

C3. Modification 3:
In the above embodiment, the main control unit 210 of the mobile phone 200 specifies the current position of the mobile phone 200 based on the information on the strength of radio waves from a plurality of base stations and the location of each base station. However, for example, the base station specifies the current position of the mobile phone 200 based on the radio wave transmitted from the mobile phone 200 as the route guidance device, and transmits the current position to the mobile phone 200, whereby the current position is acquired. It can also be set as an aspect. In addition, the position of the route guidance device may be specified based on a plurality of radio waves communicated between one base station and the mobile phone 200 as the route guidance device.

C4. Modification 4:
Map image data as image data stored in the map image database 158 of the server 150 may be stored as raster data or may be stored as vector data. The map image data transmitted to the mobile phone 200 as a terminal device carried by the user may be raster data or vector data. Further, one of map image data in the map image database 158 and map image data transmitted to the terminal device can be vector data and the other can be raster data.

C5. Modification 5:
In the above embodiment, the aspect of using the GPS has been described. However, the generation of the current position information is performed by using other satellite positioning systems (SATELLITE NAVIGATION SYSTEM) other than GPS, such as GLONASS (Global Navigation Satellite System) and Galileo. For example, the global navigation satellite system (GNSS) may be used. Further, for example, the generation of position information in the mobile terminal may be performed based only on the base station of the mobile phone. In such an aspect, the mobile terminal may be an aspect that does not include a receiver for a global navigation satellite system. Furthermore, the component which produces | generates position information in a mobile terminal can also be set as the aspect which uses together the system using a several system, for example, the system using a satellite positioning system, and the base station of a mobile telephone.

  In other words, the component that generates location information in the mobile terminal can be based on any principle or system operated by any institution as long as the current location information can be specified. Good.

C6. Modification 6:
In the above embodiment, the route network database 108 includes information on the hierarchy of points included in each arc. As a result, the route data generated with reference to the route network database 108 also includes information on the hierarchy of points included in the arcs constituting the route data. Here, the route network database may be configured to hold the hierarchy information of the node without holding the hierarchy information for the arc. Since both ends of the arc coincide with the node, the hierarchy of each section of the route can be specified even in such an aspect.

C7. Modification 7:
In the said embodiment, the 2nd type area which should move without using the means of transportation operated according to a timetable is an area which moves on foot. However, the second type section may include a section to be moved by taxi, or may include a section to be moved by a private car or bicycle.

C8. Modification 8:
In the embodiment described above, the section of the hierarchy different from the current position PP is displayed on the display panel 202 more narrowly than the section of the same hierarchy as the current position PP (see S11 in FIG. 4). However, a section located in a layer different from the current position can be displayed in a lighter color than a corresponding type of section located in the same layer as the current position. Here, “light color” means a color that has the same hue and satisfies either high brightness, low saturation, or both of a certain color.

  In such an aspect, for example, a first type section (for example, a section where a railroad is to be used) located in a layer different from the current position is included in the first type section located in the same layer as the current position. In comparison, it is displayed in a lighter color. In addition, the second type section (for example, a walking section) located in a layer different from the current position is displayed in a lighter color than the second type section located in the same layer as the current position.

  Note that the same display can be made without distinguishing between a section located in a layer different from the current position and a corresponding type of section located in the same layer as the current position.

C9. Modification 9:
In the above-described embodiment, the main control unit 210 uses the transportation means operated according to the timetable, and the second type of section to be moved without using such transportation means. The section of the seed is displayed in a different color (see step S420 in FIG. 3 and FIG. 4). However, the first type section and the second type section are displayed in different display modes by changing at least one of the displayed graphic components such as shape, pattern, size, etc., not limited to color. can do. For the two sections, “the display mode is the same” means (a) the same color, (b) the same thickness, (c) the same size, (D) It is included that at least a part of each display is occupied by a repeating pattern, and the basic elements of the repeating pattern have the same shape.

  In the above embodiment, the transfer station mark Mst has the same color and shape as the transfer station mark Msr, which is a red circle. However, the transfer station mark may be a mark having a different shape or a different size from the (transfer station) mark. However, the transfer station mark is preferably represented in the same color as the (transfer station) mark. With such an aspect, the user can operate the transfer station mark displayed on the map in anticipation that information on the means of transportation restrained by the timetable is presented.

  The transfer station mark Mst and the transfer station mark Msr have a certain color (red) and shape (see step S420 in FIG. 3 and FIG. 4). However, the boarding station mark may have a certain shape and may be displayed in a manner in which other components (pattern and color) are different. Moreover, a boarding station mark has a fixed pattern, and the other structural elements (shape and color) of a display can also be displayed in a different aspect. That is, the boarding station mark can be displayed in a certain display mode in which at least one of the shape, pattern, and color is the same. Similarly, the transfer station mark can be displayed in a certain display mode in which at least one of the shape, the pattern, and the color is the same.

  In addition, between the boarding station mark and the transfer station mark and the section, “the display mode is the same” means that (a) the color is the same, and (b) the thickness of the outline display is the same. (C) At least a part of each display is occupied by a repetitive pattern, and the shape of the basic elements of the repetitive pattern is the same.

  In addition, in the present specification, “display with different colors” includes, for example, a mode in which two displays having the same shape are displayed with different single colors, and a single color with a part of one display. It is also included when a part of the corresponding part of the other display is displayed in that color and the other part of the corresponding part is displayed in another color.

  It should be noted that the transfer station mark may not be displayed for the transfer station, but may be a mark representing the transfer station, and a mark that displays information on the transportation facility used from the transfer station when operated.

C10. Modification 10:
In the said embodiment, the information regarding the means of transportation displayed when a predetermined mark is operated is a timetable (refer FIG. 5). However, the information on the transportation means displayed when the predetermined mark is operated can be other information. For example, as a display of information displayed when a mark is operated via the input unit, a map around a station of transportation means including a ticket gate can be used. Moreover, the display of information displayed when the mark is operated may be a display including a display at which a train to be used arrives and a display (number or map) of a wharf at which a ship to be used arrives.

C11. Modification 11:
In the above embodiment, in step S455 of FIG. 8, it is determined whether or not the current position is within a circle with a radius of 500 m centering on the boarding station or transfer station. Is displayed. However, the conditions for determining whether or not to display the itinerary can be other conditions. For example, the radius of a circle that defines a range including a station serving as a reference when displaying the itinerary can be set to other values such as 400 m, 300 m, and 200 m. In addition, the reference range when displaying the itinerary can be an area where the distance to the station along the route network is equal to or less than a predetermined value. Further, it is also possible to display an itinerary table when entering a polygon in an area including a station.

C12. Modification 12:
In the above embodiment, when the condition is satisfied in step S455 of FIG. 8, the itinerary table including all the first type sections (sections using the transportation facilities) included in the route is displayed (FIG. 9). However, the displayed itinerary table displays only the next first type section from the current position on the route among all the first type sections included in the route, and the current position has not yet reached. It is also possible to display only a part of the first type sections on the itinerary, such as displaying all the first type sections that are not present.

C13. Modification 13:
In the above embodiment, the route guidance system includes the map server 150, the timetable server 170, and the mobile phone 200 as its components. However, the mobile terminal that is carried by the user and that includes the GPS unit may be provided with functions of other components such as the map server 150 and the timetable server 170. Further, the map server 150 and the timetable server 170 may be the same server. The mobile terminal exemplified as the mobile phone 200 in the above embodiment may be a so-called feature phone or a smartphone, and may be a PDA (Personal Data Assistant) or another computer as a device that does not have a telephone function. it can. In other words, the portable terminal may be any device that can be carried by the user and can identify the current position.

  That is, the route guidance system as a map display device may be one device in which each component is housed in one housing. The route guidance system can also be configured as two or more devices whose constituent elements are connected to each other via a data communication line. For each function such as a function for generating route data and a function for selecting a specific area, one or more arbitrary functions can be assigned to each device. Each function may be realized by one device, or two or more devices may be realized in cooperation. In an aspect in which two or more components are connected by a communication line, the output unit that outputs information to the user is preferably carried by the user.

C14. Modification 14:
In the above embodiment, a part of the configuration realized by hardware may be replaced by software, and conversely, a part of the configuration realized by software may be replaced by hardware. For example, a part of the function of the application software can be executed by the control circuit.
