Description

  The present invention relates to a navigation device for guiding a recommended travel route to a user in response to a search request for a recommended travel route including a starting point and a destination, and a navigation program for causing the navigation device to control operations.

  Conventionally, a navigation device is known as a device for supporting the arrival of a moving body such as a vehicle or a human at a destination. For example, the navigation device derives the current position of the moving body by GPS (Global Positioning System), and obtains a recommended moving route by route search processing based on the current position information of the moving body and the road map information.

  In such a navigation device, a route recommended for moving to a destination using a transportation system (particularly public transportation) such as a railroad or a route bus (for example, a boarding point, a transfer point, and a getting-off point) There is a route that guides the user on a route indicated by the above.

  Some navigation devices that perform such guidance notify the user of last train transfer guidance information in consideration of the travel time to the nearest station of the user's destination (see Patent Document 1).

For example, the output unit 40 outputs an image display device (display device, monitor) that displays image information and audio information. Audio output device (speaker device). The image display device displays road map information, route information, current location information of the user, etc. on the display screen, and also displays the recommended travel route to the destination on the display screen, so that the route can be visually confirmed. Is notified. Here, the “recommended travel route” includes not only a route shown as an image on the map but also a route that can be specified by a character string indicating the name of the waypoint, the moving direction, and the like.

  The sensor unit 50 has a function of measuring the current position of the navigation device 100 (that is, the current position of the user). For example, the sensor unit 50 receives a GPS signal transmitted from a GPS satellite, and positions based on the GPS signal. A GPS sensor that measures the distance, a speed sensor that measures the amount of movement (distance) from the initial position, a gyro sensor that measures the traveling (movement) direction, and the like.

  A GPS sensor is a so-called GPS receiver, receives a GPS signal radiated from a GPS satellite, measures a distance (pseudo distance) between the GPS satellite and the GPS receiver itself, and receives a plurality of satellites. Are simultaneously received to calculate the current position (GPS positioning solution) of the GPS receiver itself.

  The communication processing unit 12 has a function of executing processing for transmitting and receiving various types of information by the communication unit 60.

  The route search unit 13 has a function of executing a process for searching for a recommended movement route according to the search condition. In this example, the route search unit 13 includes a railway route search unit that searches for a recommended movement route (railway route) when moving using a railroad, and a recommended movement route (usable route that does not limit the moving means to a railroad). And an available route searching unit for searching (not shown). Here, since a well-known technique is used for the search for the railway route (the search from the current position to the station and the recommended travel route including the transfer route from the boarding station to the getting-off station), the detailed explanation here is Omitted. The search for available routes will be described in detail later (see FIG. 7). For ease of explanation, hereinafter, “transfer” refers to a change in the type of transportation (for example, a change from a train to a bus. For example, a train drop-off position, a ticket gate, a station exit, the next transportation The user moves in the order of the route up to, the next transportation entrance, the ticket gate, and the boarding position.) In addition, the route does not change, but the route changes (for example, a train connection). That is, for example, it means that the user moves in the order of the alighting position, the platform of the next route, and the boarding position.

  The determination unit 14 has a function of executing processing for determining whether or not the recommended travel route searched by the route search unit 13 satisfies a predetermined usage condition. In this example, the determination unit 14 refers to the usage conditions set by the provider or the user of the navigation device 100, for example, and determines whether the searched recommended travel route satisfies the usage conditions. The usage condition information indicating the usage conditions (for example, the railway usage conditions used as the search conditions for the railway route and the usable conditions used as the search conditions for the available routes) is stored in a predetermined storage area of the storage unit 20, for example. It shall be.

  The search unit 15 has a function of executing a process for searching for facilities based on the set search conditions. In this example, the search unit 15 sets a search condition according to the user's situation, for example, according to a predetermined rule (for example, a rule indicated by a circle with a predetermined radius centered on the current position). Search for facility information that satisfies the specified search conditions. Moreover, the search part 15 searches the facility information which satisfy | fills the set search conditions, when a search condition is set by the user.

  The guide unit 16 has a function of executing processing for guiding the recommended travel route searched for and the searched POI information (including facility information) to the user. In this example, the guidance unit 16 performs guidance for the user by displaying part or all of the recommended travel route and facility information on the display screen of the display device.

  As shown in FIG. 2, the storage unit 20 includes a road map information storage unit 21, a user information storage unit 22, a facility information storage unit 23, and a railway related information storage unit 24.

  The road map information storage unit 21 is a storage medium that stores map information divided into a predetermined grid (in this example, a rectangular range divided by a constant latitude width and latitude width). In addition to being stored in the road map information storage unit 21, this map information can be stored in an auxiliary storage device as a removable medium called an SD memory card, a CD-ROM, a DVD-ROM, or the like. Further, the map information may be downloaded via a communication network such as the Internet. In addition, the road map information storage unit 21 manages roads by representing nodes and links as road information indicating traffic regulation, road configuration, and the like. It is a storage medium for storing. That is, the route search unit 11 acquires information necessary for the route search process from the road map information storage unit 21. Hereinafter, information in which map information and road information are appropriately associated is referred to as “road map information”. Note that there are a plurality of types of road map information depending on the scale of the map and the corresponding range, and the road map information may be appropriately used depending on the environment setting.

  The user information storage unit 22 is a storage medium that stores information (user information) related to the user of the navigation device 100. The user information is information used for the navigation device 100 to provide useful information to the user.

  FIG. 3 is an explanatory diagram illustrating an example of a storage state of user information in the user information storage unit 22. As shown in FIG. 3, the user information in this example includes a current position, a home address, a station nearest to the home, an upper limit required time, and an upper limit required amount.

  Here, the current position is the current position of the user, and is a position that is a starting point when performing a route search. The route search may be configured to accept an input of the departure place by the user.

  Also, the nearest home station is the nearest station to the home address set by the user. In addition, the setting of the nearest station is good also as a structure which sets the station which a user uses, and it is good also as a structure which the control part 10 sets based on the home address set by the user. A plurality of home addresses and nearest stations may be registered.

  The upper limit required time is a time set as an upper limit of a required time of a route that can be used as a recommended travel route by the user. The upper limit required amount is an amount set as the upper limit of the required amount of the route that can be used as the recommended travel route by the user. In this example, the upper limit example that allows the same value will be described. However, time or money that does not allow the same value may be set as the upper limit in the user information. Until the upper limit required time or the upper limit required amount is set by the user, these values may not be included in the user information, or an initial value may be included.

  The facility information storage unit 23 is a storage medium that stores information about facilities (facility information). In addition, in this example, the case where the facility information (for example, information regarding an accommodation facility, a karaoke box, a cartoon cafe, a pub, a family restaurant, etc.) relating to facilities that can be provided to a user who missed the last train is stored is an example. I will explain. However, the storage unit 20 may include a storage medium that stores POI information indicating guidance objects that are not limited to facilities.

  FIG. 4 is an explanatory diagram illustrating an example of a storage state of facility information in the facility information storage unit 23. As shown in FIG. 4, the facility information in this example includes a facility name, position information, a usage fee, and a genre.

  Here, the usage fee is a fee required for using the facility. Assume that the usage fee is set in advance (for example, an average budget or usage fee for each hour). Note that the usage fee may be updated according to the user's operation, for example, by allowing the user to register the usage fee in the past as the usage fee.

  The railway-related information storage unit 24 is a storage medium that stores various information (railway-related information) related to railways such as station addresses, route maps, and timetables. In this example, the route search unit 13 searches for a railroad route with reference to railroad related information.

  Next, an outline of the navigation processing in this example will be described with reference to the drawings.

  FIG. 5 is an explanatory diagram for explaining an outline of the navigation processing. As shown in FIG. 5, in the navigation processing in this example, a route (railway route) that uses a railroad as a recommended route from the current position P to home H is searched. Then, when the current position P is departed on foot from the current time, the user misses the last train when it is determined that the last train cannot reach the nearest station 514 of the home H (the station that the user usually uses). It is determined that the return can be made cheaply by other means of transportation (for example, a train, a taxi, a bus, and a walk on another route). That is, for example, a station 511 having a train that can be boarded from the current position P is searched, and a recommended travel route from the home H through which the train that can be boarded to the nearest station (for example, the station 512) is searched. Further, in the navigation processing in this example, the route UR1 using a taxi from the station 512 to the home H (or the vicinity of the home H such as the nearest station 514) is searched, and the usage fee is calculated. If the total fee (the sum of the train and taxi usage fees) exceeds the set amount (the upper limit required amount in this example; see FIG. 3), a facility near the current position P (for example, an accommodation facility) 521-524) and guide the user. When searching for the route UR1, the route UR2 that travels from the current position P (or the taxi stand around the current location) to the home H by using a taxi is searched, the usage fee is calculated, and the route UR1 is combined. It is good also as a structure which alert | reports to a user. Further, the route differs from the route UR1 within a range not exceeding the upper limit required time and the upper limit required amount of money (for example, the user moves from the current position P to the station 511 on foot, and takes a train from the station 511 to the home H from the station 512). It is good also as a structure which travels to the station 513 which is distant from the station, searches for a route UR3) from the taxi stand around the station 513 to the home H, and guides the searched plurality of routes to the user.

  Next, the operation of the navigation device 100 in this example will be described with reference to the drawings. Note that detailed descriptions of processes not particularly related to the present invention may be omitted.

  FIG. 6 is a flowchart illustrating an example of navigation processing executed by the navigation device 100. In the navigation process, a process for guiding information according to whether or not the railway can be used is performed.

  The navigation process in this example is started in response to the control unit 10 receiving a navigation process execution request from the user of the navigation device 100, for example.

  In the navigation process, first, the control unit 10 sets a destination (step S101). In this example, the control unit 10 sets the home address included in the user information as the destination. In addition, it is good also as a structure which the control part 10 receives the setting of the destination by a user.

  When the destination is set, the control unit 10 searches for a route (railway route) whose main moving means is a railroad (step S102). In this example, the control unit 10 searches for a walking route to a station around the current position, searches for a transfer route from the station around the current position to the nearest station, and finds a route from the current position to the nearest station. Specify as a railway route. The navigation device 100 may be configured to omit the route search from the nearest station to the home address.

  When searching for the railway route, the control unit 10 determines whether the search result satisfies the railway use condition (step S103). In this example, the control unit 10 uses a condition including “use only a vehicle that travels on a railway available to the user after the search time” as the railway use condition. Here, the “search time” may be a time (current time) when the control unit 10 receives a request for execution of the navigation process, or may be a time (specified time) specified by the user. In addition, the content of “the vehicle that travels on the railroad that can be used by the user” is not particularly limited. For example, “it is a train before the last train after the search time” or “the number of transfers and types of routes after the search time” It is desirable that the conditions are set in advance or by the user in consideration of user convenience, such as “the vehicle must satisfy the conditions set by the user”.

  If it is determined that the search result satisfies the railway use condition (Y in step S103), the control unit 10 proceeds to the process in step S104 described later. On the other hand, if it is determined that the search result does not satisfy the railway use condition (N in step S103), the control unit 10 uses a recommended movement route that is not limited to the railway, based on the available condition corresponding to the user. Processing for searching for a possible route (available route search processing) is executed (step S200). The available route search process will be described later in detail (see FIG. 7).

  When the available route search process is executed, the control unit 10 displays the search result (step S104). In this example, the control unit 10 displays on the display screen of the display device a search result screen indicating a railroad route that satisfies the railroad use condition or an available route searched in the available route search process (not shown).

  When the search result is displayed, the control unit 10 determines a route (guidance route) to guide the user (step S105). In this example, the control unit 10 displays an outline of a route as a search result so as to be selectable, and determines the route selected by the user as a guide route.

  When the guide route is determined, the control unit 10 starts route guidance (step S106), and ends the processing here. In this example, the control unit 10 displays the details of the route selected by the user on the display screen. The control unit 10 may guide the user to the destination (home address or home nearest station) based on the current position of the user and the recommended travel route information (guide route information) indicating the guide route. . In this case, for example, the navigation device 100 may display a part of the recommended travel route including the current position and guide the user by appropriately outputting sound near an intersection or the like.

  Note that the order and contents of the steps constituting the navigation process are not limited to those shown in FIG. 6. For example, in the process of step S <b> 104, the control unit 10 selects a railway route that does not satisfy the railway use condition, Search results according to the user's situation, such as a configuration to display selectable rail routes that do not satisfy or a configuration in which the control unit 10 searches for a rail route that satisfies the rail usage conditions when searching for a rail route (step S102). Any configuration can be used as long as it can provide. In this case, for example, when the control unit 10 is able to search for a railway route (that is, when a railway route that satisfies the railway usage condition is found), the searched railway route is displayed and the railway route cannot be searched. The available route search process may be executed.

  FIG. 7 is a flowchart illustrating an example of an available route search process executed by the navigation device 100. In the available route search process, a process for searching for an available route, which is a recommended travel route when allowing the main travel means to include travel means other than railways, is performed.

  In the available route search process, first, the control unit 10 sets a moving means (step S201). In this example, the control unit 10 sets taxis, buses, and walks as moving means. In addition, it is good also as a structure which the control part 10 receives the setting of the moving means by a user. In addition, although the railway route includes movement on foot, walking as a movement means in the case of an available route can be a main movement means (for example, movement means including long-distance movement). Different from means. That is, when searching for a railway route in this example, the control unit 10 searches for a walking route to a station around the current position. On the other hand, when searching for an available route in the present example, the control unit 10 may change the target from the current position depending on the situation of the user (for example, in a situation where the transportation facility such as a railroad or a taxi has not been functioning for a while). Explore the walking route to the ground.

  When the moving means is set, the control unit 10 searches for a recommended moving route that is not limited to the railway as a usable route (step S202). In this example, the control unit 10 searches for a recommended moving route when moving from the current position to the home address in consideration of the set moving means. That is, the usable conditions are the same general conditions (for example, the shortest route) as in the case of searching for a railway route except that “the moving means is not limited to the railway”. It should be noted that the availability condition does not have to be a general recommended travel route search condition. For example, the availability condition may be set by the user. In this example, the control unit 10 estimates a time (required time) that may be required when the user moves along the searched available route and an amount (required amount) that may be required. These estimations may be configured to use information published by various transportation facilities, or may be configured to use an original calculation formula.

  In this example, control part 10 handles a taxi stand as a taxi boarding position. In addition, when the control part 10 uses a taxi as a moving means, it is good also as a structure which guides a user to which way it is good to catch a taxi while walking. In this case, for example, the control unit 10 may preferentially select a street through which a taxi can pass as a route moving on foot. Moreover, it is good also as a structure which guides from which side of the road the control part 10 should get on, for example, based on a user's present position and a recommended movement path | route, when a user gets on a taxi.

  When searching for an available route, the control unit 10 determines whether there is an available route whose required time does not exceed the upper limit required time in the search result (step S203). In this example, the control unit 10 refers to the user information and determines whether there is an available route whose required time does not exceed the upper limit required time. Moreover, the calculation result of the time considered to be necessary when moving the available route is an estimated value, and it is not an essential condition that it is a strict calculation method. Therefore, the detailed description here about the calculation method of required time is abbreviate | omitted.

  If it is determined that there is no available route whose required time does not exceed the upper limit required time in the search result (N in step S203), the control unit 10 determines the facility route that is a recommended travel route to the facility around the current position. Is executed (facility route search process) (step S300), and the process proceeds to step S104 in the navigation process (see FIG. 6). In this example, the control unit 10 displays the facility route searched in the facility route search process as a search result (step S104). The facility route search process will be described in detail later (see FIG. 8).

  On the other hand, if it is determined that there is an available route whose required time does not exceed the upper limit required time in the search result (Y in step S203), the control unit 10 sets the required amount in the available route to the upper limit required amount. It is determined whether there is an available route that does not exceed (step S204). In this example, the control unit 10 refers to the user information and determines whether there is an available route whose required amount does not exceed the upper limit required amount. Moreover, the calculation result of the amount considered to be necessary when moving the available route is an estimated value, and it is not an essential condition that it is a strict calculation method. Therefore, a detailed description of the required amount calculation method is omitted here.

  If it is determined that there is no available route whose required amount does not exceed the upper limit required amount (N in step S204), the control unit 10 proceeds to a process in step S300 described later (see FIG. 8).

  On the other hand, if it is determined that there is an available route whose required amount does not exceed the upper limit required amount (Y in step S204), the control unit 10 proceeds to the process of step S104 in the navigation process (see FIG. 6). In this example, the control unit 10 displays an available route whose required amount does not exceed the upper limit required amount as a search result (step S104).

  Note that the order and contents of the steps constituting the available route search process are not limited to those shown in FIG. 7. For example, in the process of step S <b> 104, the control unit 10 selects at least the upper limit required time and the upper limit required amount. A configuration in which an available route that does not satisfy any one of them can be selected as an available route that does not satisfy at least one of the upper limit required time and the upper limit required amount, or the control unit 10 searches for an available route. Sometimes (step S202), any configuration that can provide the user with a recommended travel route that replaces the railway route, such as a configuration that searches for an available route that satisfies the upper limit required time and the upper limit required amount of money. In this case, for example, when the control unit 10 can search for an available route (that is, when an available route satisfying the upper limit required time and the upper limit required amount is found), the searched available route is displayed and used. It is good also as a structure which performs a facility route search process, when a possible route cannot be searched.

  FIG. 8 is a flowchart illustrating an example of facility route search processing executed by the navigation device 100. In the facility route search process, a process for searching for a facility route which is a recommended travel route when the destination is a facility around the current position is performed.

  In the facility route search process, first, the control unit 10 sets a facility search condition (step S301). In this example, the control unit 10 sets the current position and the facility genre set by the user as search conditions. The setting timing and setting contents of the facility search condition by the user are not particularly limited. For example, the control unit 10 may display a search condition setting screen by the user after searching for an available route. It is good also as a structure which receives the setting of a movement distance and a usage fee from a user.

  When the facility search condition is set, the control unit 10 searches for a facility that satisfies the set search condition (step S302). In this example, the control unit 10 refers to the facility information storage unit 23 and searches for a facility that satisfies the search condition.

  When the facility is searched, the control unit 10 displays the search result (step S303). In this example, the control unit 10 displays at least a part of the facility information indicating the searched facility on the display screen of the display device (not shown). In addition, the display method of a search result is not specifically limited, It is good also as a structure which displays the map image which has arrange | positioned the icon which shows the position of a facility, and when a search result contains a some facility, a predetermined priority rule ( For example, it is good also as a structure which displays the facility name of a specific number of facilities according to the order close | similar to a present position, or the order with a cheap usage charge.

  When the search result is displayed, the control unit 10 determines a facility (guidance facility) to be guided to the user (step S304). In this example, the control unit 10 determines the facility that has received the user's selection from the facilities displayed on the display screen as the guidance facility.

  When the guidance facility is determined, the control unit 10 searches for a facility route that is a recommended travel route from the current position to the guidance facility (step S305), and proceeds to the processing of step S104 in the navigation processing (see FIG. 6). In this example, the control unit 10 searches for a recommended movement route when the user moves on foot from the current position to the guidance facility. In this case, the control unit 10 may search for a recommended movement route when moving from the current position to the facility using a moving means other than walking (for example, a taxi).

  As described above, in the above-described embodiment, the navigation apparatus 100 that guides the recommended travel route to the user in response to the search request for the recommended travel route including the departure place and the destination is performed at the search time (for example, the current time). Time), departure location (for example, current location), and destination (for example, home address), a recommended route for traveling by rail from the departure location to the destination A search is made (for example, step S102), and it is determined whether or not the railroad route satisfies a predetermined railroad use condition (for example, only using a vehicle traveling on a railroad that can be used by the user after the search time). (E.g., step S103), if it is determined that the railway use condition is not satisfied, the available condition corresponding to the user (e.g., the shortest route in which the moving means is not limited to the railway) Search conditions that are set when the travel means is searched for an available route that is a recommended travel route that is not limited to the railway (for example, step S202) and the railway use condition is not satisfied. The facility is searched based on the information (for example, step S300), and the searched facility is guided (for example, steps S303, S304, S305), so that more effective information can be provided at the end of the train. .

  That is, for example, it is assumed that a user who intends to return to his / her home or accommodation by a train notices that he / she has missed the last train as a result of a route search using the navigation device 100. In such a case, the navigation apparatus 100 proposes how to return by other moving means (for example, a train running on a route different from the route searched by the user, a taxi, a bus, or walking). Since the use of facilities satisfying the search conditions is proposed, it is considered that the information is effective for the user.

  Although not particularly mentioned in the above-described embodiment, when the navigation device 100 determines that the search result does not satisfy the railway use conditions (for example, N in step S103), a screen indicating that is displayed. At the same time or immediately after, a screen for guiding the available route or the facility route may be displayed. In this case, for example, the navigation device 100 may display a screen indicating that the search result of the railway route does not satisfy the railway use condition after the search for the available route or the facility route is completed. By adopting such a configuration, it becomes possible to guide the available route and facility route to the user at a time when the user's interest is easily obtained.

  Further, in the above-described embodiment, the case where the navigation device 100 performs the available route search process has been described. However, the configuration in which the navigation device 100 searches for a facility by omitting the available route search process (or the available route). The facility may be searched separately). That is, when the navigation device 100 searches for a railroad route (for example, step S102) and determines that the search result (that is, the railroad route) does not satisfy the railroad use conditions, the facility is based on the set search conditions. (For example, step S300), and the searched facility may be guided (for example, steps S303, S304, S305). By adopting such a configuration, it becomes possible to guide a user to an effective facility at the time of the last train regardless of a search result of available routes.

  In the above-described embodiment, the navigation device 100 determines whether the searched available route can be moved in a time less than the upper limit required time or an amount less than the upper limit required amount (for example, steps S203 and S204). The facility is searched based on the set search condition (for example, step S301) (for example, step S302) in response to the determination that it is not movable (for example, N in step S203, N in S204). Therefore, it is possible to provide useful information that can compare the case where the user uses a moving means other than the railway and the case where a user uses a facility such as an accommodation facility. Note that the navigation device 100 may use an element (for example, walking distance) that can set an upper limit for the user in addition to time and money as an element for determining whether or not to search for a facility.

  In the above-described embodiment, the case where the facility search condition includes the usage fee has been described. However, the navigation apparatus 100 includes the upper limit required amount that is the upper limit of the required amount of the route that the user can use as the recommended travel route. Facility information stored in the facility information storage unit 23, including a user information storage unit 22 that stores user information, and a facility information storage unit 23 that stores facility information that is information about facilities including usage charges and location information. It is good also as a structure which searches the plant | facility information which shows the plant | facility whose usage fee does not exceed upper limit required amount from among. By adopting such a configuration, it becomes possible to guide a facility in a price range according to the user without accepting the setting of the usage fee by the user when searching for the facility.

  In the above-described embodiment, the railroad use condition includes using only a vehicle that travels on the railroad that can be used by the user after the search time, and the navigation device 100 can be used from the departure place (for example, the current position). A station that can be moved and that satisfies the specific conditions of the route to the destination (for example, home address) is specified as a disembarking station. A non-railway route (for example, an available route) that is a recommended travel route when moving from the destination to the destination is searched (for example, step S202), and the time and amount required for using the non-railway route are estimated. (For example, step S202), based on the estimated time and price, it is determined whether or not the route from the departure point including the non-railway route to the destination is an available route. (For example, step S203, S204) since a configuration, it is possible to provide useful information that can select a route the user in consideration of the balance of time and money.

  In the above-described embodiment, when user information has already been created, that is, for example, as a setting in the previous stage, registration of a home address (for example, search for a station around the home or calculation of a taxi usage fee) ), Set the walking distance to your home (for example, you do n’t have to take a taxi if you ’re at a station within the set range), set the price (for example, use to search for routes within the set amount), Initial setting of distance setting (for example, used to search for a station that can take a train from the current location. Specifically, for example, if the distance is set to 1 km, the station can be reached within about 15 minutes and the train is in time) In the case of the configuration, each setting is described afterwards (for example, after searching for a plurality of recommended travel routes, a user's setting operation is accepted, and information is set based on the set user information. It may be configured Komu Ri.

  In the above-described embodiment, the case where the navigation device 100 displays the search result has been described. However, in response to the navigation device 100 receiving a request for starting the navigation process, a train that the user can still board is used. Extract, search for the nearest station in your home, search for the nearest station for trains that can be boarded from your current location (especially search for the time required), and check whether you can walk from your nearest station If it is judged that walking is possible, the route to the home is also searched, the fee when using a taxi from the nearest station to the home is calculated, whether the calculation result falls within the set amount, and it does not fit If it is determined that, part or all of the process of searching for accommodations near the current location, karaoke boxes, manga cafes, taverns, family restaurants, etc. , Without requiring a user operation) is performed, it may be configured to output the result.

  Although not specifically mentioned in the above-described embodiment, the navigation device 100 updates the value of at least one of the upper limit required time and the upper limit required amount based on the current position and the destination of the user. It is good also as a structure. In this case, for example, the user information includes the time or amount per unit distance, and the navigation apparatus 100 calculates the upper limit required time or the upper limit required amount according to the distance between the current position and the destination, and according to the calculation result It is good also as a structure which updates user information.

  A management server (not shown) connected to the communication network may be configured to execute some or all of the various processes in the above-described embodiment. Moreover, it is good also as a structure provided with the memory | storage part which memorize | stores the various information in the embodiment mentioned above in the management server not shown connected to the communication network.
