(Embodiment)
Exemplary embodiments of a presentation device, a presentation method, and a presentation program according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram illustrating an example of a functional configuration of the presentation device according to the embodiment. A presentation device 100 according to the embodiment includes an acquisition unit 101, a route determination unit 102, and a presentation unit 103. In the embodiment, a single server has each of these functions. As will be described later, a plurality of servers distributed for each function in FIG. 1 may be used, or a single client (terminal) may have the function of the presentation device 100 without using a server.

  The acquisition unit 101 acquires event information including an event type, an event holding range (an influence range that affects route search determination), and a holding time zone. The types of events include, for example, a fireworks display and an international soccer game. The event holding range is set, for example, in latitude and longitude, administrative districts, etc., and the event organizer etc. sets the range centering on the event location in advance and notifies in advance in order to regulate traffic etc. . The event holding time zone is a date and time zone, and includes, for example, a date and time zone (for example, 16:00 to 18:00).

  The acquisition unit 101 acquires this event information via a network such as the Internet. As the event information, for example, the acquisition unit 101 acquires information distributed by VICS (Vehicle Information and Communication System: registered trademark).

  The route determination unit 102 has a route search function for generating a guide route. For example, based on information such as the user's current location and destination input at the time of a route search request from the user's terminal, the route search from the current location to the destination (road) is performed with reference to map information (map database) To do. At this time, based on the cost such as the travel time or the travel distance, for example, a route search is made for a route having a low search cost (can be reached in a short time or distance). At this time, a plurality of routes can be output as candidates in order of search cost.

  Then, when a part of the route searched for passes the road (evaluation target road) within the holding range within the event holding date and time (holding time zone), the route determining unit 102 guides the route according to the type of the event. Change the contents of. For example, in the case of a certain event type, the route searched at least during the event holding time zone with the cost of the evaluation target road being increased is determined as the guidance route. In the case of another certain event type, the route searched without considering the event information in the holding time zone is determined as the guide route.

  The route determination unit 102 stores and holds the participant behavior prediction information in which the event information acquired by the acquisition unit 101 is associated with the congestion status of roads (evaluation target roads) within the holding range for each event information. The participant behavior prediction information is, for example, a list of the congestion situation of roads (evaluation target roads) within the holding time zone or outside the holding time zone for each event.

  Based on the participant behavior prediction information (details will be described later) including the event information, the route determination unit 102 determines the guidance route when passing through the road (evaluation target road) within the holding range within and outside the event holding time zone. Change the contents.

  Here, it will be described that the congestion state varies depending on the event range within and outside the event time period due to different event types.

  First, the case where it is possible to pass through the holding range without congestion even within the holding time period depending on the event type will be described. For example, if the event type is a fireworks display, the participants are watching the fireworks within the time period, and there is little movement of participants (cars) within the holding range, and there is little congestion within the holding range (participants Therefore, the route determination unit 102 determines the route searched without considering the event information during the holding time period as the guide route.

  On the other hand, there are many movements of participants (cars) entering or leaving the holding area outside the holding time period (referring to a predetermined period before the start time and a predetermined period after the end time) (participant behavior prediction information) Therefore, the route determination unit 102 determines, as a guide route, a route that avoids at least the holding range outside this holding time period.

  Similarly, even if the event type is an international football match, participants are watching in the stadium during the holding time, and there is little movement of participants (cars) within the holding range, and congestion within the holding range. Since there are few (participant behavior prediction information), the route determination unit 102 determines the route searched without considering the event information as the guidance route during the holding time period.

  On the other hand, because there are many movements of participants (cars) entering or leaving the holding range outside the holding time period (predetermined period before the start time and predetermined period after the end time) (participant behavior prediction information) The route determination unit 102 determines, as a guide route, a route that avoids at least the holding range in the holding time zone.

  Also, if the event type is a sports team winning parade, both within and outside the holding time period (predetermined period before the start time and predetermined period after the end time) are within the holding range, or from the holding range Since there are many movements of participants (cars) leaving (participant behavior prediction information), the route determination unit 102 determines, as a guide route, a route that avoids the holding range both in the holding time zone and outside the holding time zone.

  When the route determination unit 102 determines a route that passes or avoids the holding range outside the holding time period (a predetermined period before the start time and a predetermined period after the end time) as a guide route, The roads within the holding range based on the congestion (participant behavior prediction information) according to the stage of the outside time zone for each event type. The contents of the guide route when passing through (evaluation target road) can be changed.

  For example, the route determination unit 102 has a large congestion in the external time zone 1 (less than 1 hour before the start), a small congestion in the external time zone 2 (1 hour or more and less than 2 hours before the start), and an external time zone 3 (start). Based on the information (participant behavior prediction information) that there is no congestion (smooth) for the previous 2 hours or more), the contents of the guide route when passing the road (evaluation target road) within the holding range in each outside time zone change.

  In addition, the route determination unit 102 uses a setting (participant behavior prediction information) that uniformly increases the passage cost (degree of ease of passing) for all roads (evaluation target roads) within the holding range, as well as the type of event. Depending on the situation, the amount of increase in the passage cost of the central part and the peripheral part of the holding range may be set differently. For example, in the case of a fireworks display, since the participants are more concentrated in the center of the holding range, the passing cost is increased because it is difficult to pass, and the passing cost is increased because it is easier to pass in the peripheral part.

  In addition, the route determination unit 102 can change the size of the event holding range according to the type of event. For example, in the case of a fireworks display, the participants are watching fireworks during the event period, and there is little movement of participants (cars) within the event range, and there is less crowding within the event range (participant behavior prediction information) Therefore, the size of the holding range will not be changed during the holding time period.

  On the other hand, because there are many participants (cars) that enter or leave the holding area outside the holding time period (a predetermined period before the starting time and a predetermined period after the ending time), a predetermined period outside the holding time period. Performs a change (referred to as an influence range) that widens the holding range (for example, by a predetermined block outward). If there is a change in the holding range, the route determination unit 102 considers the changed holding range (influenced range) and determines whether or not there is a passage to the affected range as the guidance route.

  This range of influence is not limited to increasing / decreasing the area (range) based on the holding range, but may include a specific main road or road (link) leading to the holding range.

  Further, the route determination unit 102 may set an entry cost (degree of ease of entering / exiting) for each direction of entering / exiting the holding range according to the time zone based on the holding time zone of the event whose guide route is changed. For example, during the predetermined period before the start time of the event holding time zone, it is difficult to enter the holding range, so the entry cost in the direction to enter is high, and it is easy to get out of the holding range, so the entry cost in the direction to exit is low (participation) Behavior prediction information). The predetermined period after the end of the event time period is set at a cost opposite to that before the start time.

  As described above, the determination of the guidance route by the route determination unit 102 takes into consideration the holding range and various costs (participant behavior prediction information) from among a plurality of route candidates first searched by the route search (evaluation target). The route search may be performed in consideration of the holding range and various costs in addition to the determination including or excluding the passage of the road.

  The presentation unit 103 presents the guidance route determined by the route determination unit 102. For example, the guide route can be presented to the user by display or voice. Also, the result (guide route) determined by the route determination unit 102 based on the route search request is transmitted to the user's terminal via a network such as the Internet, and the terminal presents the guide route to the user by display or voice. be able to.

  In the above configuration example, the presentation device 100 is configured by a server and a guide route is transmitted to the user. However, each configuration of the presentation device 100 may be configured by a user terminal.

  FIG. 2 is a flowchart illustrating an example of a processing procedure of the presentation device according to the embodiment. The example of a process which the presentation apparatus 100 performs when a route search is requested | required from a user's terminal is shown.

  First, the presentation apparatus 100 acquires event information including an event type, an event holding range, and a holding time zone (step S201).

  Next, the presentation device 100 refers to map information (map database) based on information such as the user's current location and destination input at the time of a route search request from the user's terminal, and a route from the current location to the destination. Route search for (road).

  The presentation device 100 changes the content of the guide route according to the type of the event when a part of the route searched for passes the road (evaluation target road) within the holding range within the holding time zone of the event. (Step S202). Case 1 is a case where congestion is small when passing through a road (evaluation target road) within the holding range within the event holding time zone. In this case (step S202: Case 1), the presentation device 100 determines the route searched without considering the event information as the guide route (step S203).

  Case 2 is a case where the vehicle is congested when passing a road (evaluation target road) within the holding range within the event holding time zone. In this case (step S202: Case 2), the presentation apparatus 100 determines a route that avoids the holding range as a guide route (step S204).

  Thereafter, the presentation device 100 presents the guide route determined in step S203 or step S204 to the user by display or the like (step S205).

  Although not shown in the processing example of FIG. 2, the presentation device 100 also performs a process of changing the size of the event holding range according to the type of event. For example, in the event of watching and watching events, during the holding time period during the holding time period, because the movement of participants (cars) within the influence range that changed the holding range is less and there is less crowding within the influence range, Do not change the size of the affected area. On the other hand, because there are many movements of participants (cars) entering or leaving the affected area outside the holding time period (the predetermined period before the start time and the predetermined period after the end time), the predetermined period outside the holding time period. Changes the influence range (for example, by a predetermined block outward).

  According to the above embodiment, when a part of the route obtained by the user-requested route search passes the road within the holding range during the event holding time period, the holding range according to the type of the event. A route that passes through the road within the holding range is presented, or a route that avoids the road within the holding range is presented. Whether to present a route that passes the road within the holding range according to the type of event not only within the holding time zone but also outside the holding time zone (a predetermined period before the start time and a predetermined period after the end time) Alternatively, a route that avoids a road within the holding range can be presented. As a result, a route search according to the event type can be performed, and a route according to the congestion condition of the road in the holding range at the time of the event can be presented to the user.

  For example, if the event type is such that the road within the holding range during the holding period is easy to pass, the user can search for the guide route passing through the holding range and not showing the route avoiding the holding range. By following the route, you can reach the destination with reduced time and distance. Thereby, the reliability of the searched route can be improved and presented to the user.

  In addition, the size of the holding range can be changed according to the type of event and the holding time zone, and a route that takes into consideration the different holding ranges within the holding time zone (outside) can be presented for each event type. Furthermore, it becomes possible to present a route that takes into account the ease of passage of the central part and the peripheral part of the holding range within the holding range according to the type of event. It is possible to present a route that takes into account the degree of ease of entering and exiting depending on the direction of entering and exiting the holding range according to the type of event and the holding time zone. As a result, the reliability of the searched route can be further improved.

  Next, examples of the present invention will be described. In the embodiment, the navigation device 300 is mounted on the user's vehicle, the navigation device 300 requests a route search to the server 400 having the function of the presentation device 100, and the server 400 performs navigation as a response to the route search.

Also, a part of the function of the presentation unit 103 of FIG. 1 (function of transmitting a guide route to the user navigation device 300) can be realized using the communication I / F 414 of FIG.

  When the server 400 illustrated in FIG. 4 is configured to transmit the guidance route to the navigation device 300 of FIG. 3, for example, the navigation device 300 does not have a route search function and the current location necessary for the route search with respect to the server 400. Or a simple function having only a function of transmitting a route search request for a destination or the like and a function of displaying (presenting) the guide route corresponding to the event received from the server 400. Even when the navigation device 300 is configured to execute processing related to a normal route search, it is possible to receive and display (present) the guide route corresponding to the event without particularly adding hardware or the like.

(Example of presentation device presentation processing)
Next, a processing example in which the server 400 is used as the presentation device 100 and the server 400 transmits the above-described guidance route to the user (navigation device 300) will be described.

  FIG. 5 is a chart illustrating an example of participant behavior prediction information held by the server of the embodiment. The route determination unit 102 determines the guide route described above with reference to the participant behavior prediction information 500 described in FIG. For example, when a route based on the current location and the destination is searched, and there is a route that passes the holding range on the searched route at the time of the event, the participant behavior prediction information 500 determines whether or not to guide this route. To determine.

  The participant behavior prediction information 500 stored and held by the route determination unit 102 includes an event type 501 that is event information acquired from VICS and the like, and accompanying information 502. The accompanying information 502 is the date and time of the event, the time zone, and road regulation information (such as traffic closure) for the event range.

  In the participant behavior prediction information 500 of the example shown in FIG. 5, each information of the pre-start prediction information 511, the in-event prediction information 512, and the post-end prediction information 513 generated based on the event type 501 and the accompanying information 502. Is associated with each event. The route determination unit 102 stores and holds the participant behavior prediction information 500.

  Pre-start prediction information 511, in-event prediction information 512, and post-end prediction information 513 of the participant behavior prediction information 500 are an event date and time (holding time zone) for each event type including an event type 501 and accompanying information 502, respectively. It is the information which shows the congestion condition of the road (evaluation object road) in the holding range in.

  For example, in the event type 501 “Festival”, the information of the pre-start prediction information 511 indicates that the congestion in the holding range before the holding time period (a predetermined period before the starting time) is “smooth (no congestion)”. . Further, the information of the during-event prediction information 512 indicates that the congestion in the holding range within the holding time period is “congested”. The post-end prediction information 513 indicates that the congestion in the holding range after the holding time period (a predetermined period after the end time) is “congested”.

  The pre-start prediction information 511, the in-event prediction information 512, and the post-end prediction information 513 of the participant behavior prediction information 500 are current congestion situations according to the event holding time period. The route determination unit 102 acquires and generates a road congestion situation transmitted from a vehicle (for example, the navigation device 300 as a probe car) that travels in the event holding range during the event holding time (including before and after). To do.

  Then, the route determination unit 102, when requesting a route search from the user, based on the participant behavior prediction information 500, event information (event type 501 and accompanying information 502), pre-start prediction information 511, in-event prediction information 512. Based on one of the post-end prediction information 513, when a part of the search route passes the event holding range during the event holding time period, the event passing range is passed as a guide route to be presented to the user. Whether or not (avoid).

  Further, the route determination unit 102 refers to event information held in the past, and based on attribute matching of the event type 501 (for example, the same event type 501), the pre-start prediction information 511 of the past event information “For example, , “Smooth”, in-event prediction information 512 “crowded”, and post-end prediction information 513 “crowded” may be generated.

  In addition, for each event information (event type) 501, the traffic jam time after the start of the event is determined according to the size of the holding range, and the respective periods of the pre-start prediction information 511 and the post-end prediction information 513 are generated for each event type. (For example, 30 minutes or 1 hour).

  Further, although not shown in the participant behavior prediction information 500 of FIG. 5, the participant behavior prediction information 500 further includes congestion by a plurality of time zones (outside time zones) before and after the start described above. The prediction information may be held. Also, for roads within the scope of the event (evaluation target roads), information on the settings (participant behavior prediction information) that are all uniform passage costs (degree of ease of passing) for each event type, and the center of the event scope And setting information with different passing costs in the peripheral portion may be held. Furthermore, information on the influence range in which the size of the event holding range is changed according to the type of event may be held. Furthermore, information on the entry cost (degree of ease of entering / exiting) for each direction of entering / exiting the holding range for each event time zone may be held.

(Guidance information presentation process by server)
FIG. 6 is a diagram for explaining guidance information presentation processing by a system including a server and a navigation device according to the embodiment. The server 400 collects event information performed in each area A to n. The size of each area A to n is set according to the holding range of the event, and is set in a range that is at least larger than the holding range Sa of the event.

  For example, the acquisition unit 101 of the server 400 indicates the congestion state of the road at the time of holding each event from the navigation device 300 provided in the vehicle 602 located in the event holding range Sa to Sn of each region A to n. Get from. The vehicle 602 transmits the position and the congestion state (for example, traveling speed) to the server 400 over time (functions as a probe vehicle that transmits information to the server 400).

  The acquisition unit 101 of the server 400 acquires event information by communication connection to a VICS (information center) 601 or the like.

  The route determination unit 102 of the server 400 has a database 102a, collects the congestion status of each region A to n acquired from each vehicle 602 for each event holding time, and stores it in the database 102a. And the server 400 produces | generates said participant action prediction information 500 based on the event information for every event, and the congestion condition according to each area An, and stores it in the database 102a.

  Thereby, the participant behavior prediction information 500 for each event held in the past is stored and held in the database 102a, and the participant behavior prediction information 500 reflecting the latest congestion situation for the currently held event is stored. It will be stored.

  Then, it is assumed that route guidance is requested from the user of a vehicle 612 (navigation device 300) to the server 400. In this vehicle 612, position information such as the current location and the destination is transmitted to the server 400. Thereby, the route determination unit 102 of the server 400 searches for the route of the vehicle 612.

  When the route determination unit 102 searches for a route, when a part of the route of the vehicle 612 passes an event (the event holding range Sb in the region B in the example of FIG. 6), the route determination unit 102 predicts the participant behavior. The guide route R to be presented to the vehicle 612 is determined with reference to the information 500 and transmitted to the navigation device 300 of the vehicle 612. As described above, the guide route R is a route that passes through the event holding range or a route that is avoided.

  The navigation device 300 of the vehicle 612 presents the guide route R transmitted from the server 400 to the user by display or the like. As a result, the user can travel according to the guidance route R presented from the server 400 without considering the event holding range and time when requesting the route search, thereby being affected by traffic congestion due to the event. Without having to travel to the destination.

  FIG. 7 is a flowchart illustrating an example of a guidance information presentation process executed by the server of the embodiment. First, when a route search request including the current location and the destination is made from the user device (for example, the navigation device 300) to the server 400, the server 400 starts a route search process (step S701).

  At the time of route search, the server 400 (route determination unit 102) acquires the congestion status of the road in the event holding range from the VICS (information center) 601 or a vehicle in the vicinity of the event holding range, and the participant of the corresponding event. Action prediction information 500 is generated. Then, based on this participant behavior prediction information 500, the server 400 determines the congestion status of roads (evaluation target roads) within the event holding range when passing the searched route. In the example of FIG. 7, the server 400 (route determination unit 102) refers to the participant behavior prediction information 500, and the evaluation target road within the event holding range is outside the congestion range or outside the congestion time zone. It is determined whether it exists (step S702).

  Note that when the user searches for a route, the user's vehicle does not actually reach the event holding range. When searching for a route, the server 400 obtains a passing time when the user's vehicle passes near the event holding range. Then, the server 400 determines the congestion status of the road (evaluation target road) within the event holding range at this passage time (step S703).

  The server 400 (route determination unit 102) determines that the road (evaluation target road) in the event holding range at the passage time is not congested (step S703: Yes) or is congested in the determination in step S703. One of (Step S703: No) is determined. For example, if the evaluation target road is out of the congestion range or outside the congestion time zone, it is determined that the road is not congested (step S703: Yes). Further, if the evaluation target road is within the congestion range or the congestion time zone, it is determined that the road is congested (step S703: No).

  Then, if the determination result in step S703 is Yes, the server 400 (route determination unit 102) does not have to consider the influence of congestion when passing through the event holding range. The route is searched without changing (step S704).

  On the other hand, if the determination result in step S703 is No, the server 400 (route determination unit 102) needs to consider the influence of congestion when passing through the event holding range. Then, the cost is increased corresponding to the degree of congestion (step S705), and the route search in step S704 is executed including the change in the cost increase for the evaluation target road.

  The processing up to step S704 is executed for each road (link) on the route from the user's current location to the destination, and the server 400 (route determination unit 102) determines whether the searched route has reached the destination. (Step S706).

  When the searched route has reached the destination (step S706: Yes), the server 400 (route determining unit 102) evaluates the cost of the entire searched route (step S708), and ends the route search (step S709). . Thus, the server 400 (route determination unit 102) presents the searched route to the user as the guidance route R. At this time, the server 400 transmits the guide route R by communication to the user's navigation device 300, and the navigation device 300 presents the received guide route R to the user by display or the like. When the searched route has not reached the destination (step S706: No), the next evaluation target road (link) is acquired from the map DB (step S707), and the process returns to step S703.

  The guide route R presented to the user includes a plurality of route candidates by time and distance based on the cost evaluated in step S708, and the user selects the guide route R by time and distance from the route candidates. be able to.

(Display example of guidance route R)
FIG. 8 is a diagram illustrating an example of presentation of guidance information according to the embodiment. The guidance information shown in FIG. 8 is a map screen near the event holding range displayed by the navigation device 300 of the user. As shown in the figure, on the map screen, the event holding range Sb is displayed together with the road, and the guide route R received from the server is displayed. Also, information on what kind of event it is, such as the type of event, may be displayed in characters.

  In the example shown in FIG. 8, the guide route R passes through the holding range during the event holding period. This event type is “appreciating / watching” shown in FIG. 5 and the congestion status indicated by the during-event prediction information 512 is “smooth”, so that the holding range Sb of the event being held at the time of 19:00 is set as the event type. It is a route to pass. Even during the event period, as shown in the participant behavior prediction information 500 in FIG. 5, the congestion status in the event range during the event period varies depending on the event type, so the guide route R varies depending on the event type. become.

  As a result, during the event holding period, the route for avoiding the event holding range Sb was conventionally guided. However, as shown in FIG. 8, for example, based on the event holding time and the passage time. The route passing through the event holding range Sb during the event holding period can be presented to the user as the guide route R. In this case, the user can efficiently reach the destination while saving time and distance without performing unnecessary avoidance.

  Further, not limited to the above example, the server 400 (route determination unit 102) can determine the guidance route R in more detail using other information stored in the participant behavior prediction information 500. For example, as the participant behavior prediction information 500, the congestion of the outside time zone 1 (less than 1 hour before the start) before the start of the event, the congestion of the outside time zone 2 (1 hour to less than 2 hours before the start), When there is information that there is no congestion (smooth) in outside time zone 3 (2 hours or more before the start), refer to this and pass roads within the holding range (evaluation target road) in each outside time zone The contents of the guide route R can be changed.

  Furthermore, the server 400 (the route determination unit 102), as other information stored in the participant behavior prediction information 500, sets all of the roads (evaluation target roads) within the holding range to a uniform passing cost for each event type. The contents of the guide route R when passing through the road (evaluation target road) within the holding range can be changed with reference to the setting of different passing costs between the central part and the peripheral part of the holding range.

  FIG. 9 is a diagram illustrating another example of presentation of guidance information according to the embodiment. In the above embodiment, as shown in FIG. 8, the event holding range is configured to be presented to the user using the holding range acquired from the VICS (information center) 601 or the like as it is. In the example shown in FIG. 9, not only the event holding range Sb but also an influence range Sba that is a predicted congestion occurrence area that changes at each event holding time is displayed. For example, the holding range Sb and the influence range Sba may be displayed simultaneously by different display colors or by changing the display transparency.

  In the event, the traffic jam occurrence prediction area Sba is changed by a participant who enters and exits the holding range Sb on the basis of the holding time. The example shown in FIG. 9 is the case of the current time (16:10) immediately after the event holding time (end time 16:00). As described above, at the time immediately after the end of the event, a large number of event participants move outward from the event holding range Sb. In such a case, the server 400 (route determination unit 102) sets a range wider than the event holding range Sb by a predetermined block (for example, one block) as an influence range Sba that means a predicted congestion occurrence area.

  The server 400 holds this influence range information as accompanying information of the corresponding event type “parade” in the participant behavior prediction information 500 shown in FIG. Then, the server 400 (route determination unit 102) searches for a route using the event influence range Sba as an evaluation target road during the route search. Thus, conventionally, the route for avoiding only the event holding range Sb has been guided. However, according to the embodiment, as shown in the example of FIG. It is determined whether or not the route included in the influence range Sba before and after the holding period is passed.

  In addition, many participants enter the holding range Sb before the start based on the event time, and many participants exit the holding range Sb after the end. For example, the server 400 (route determination unit 102) increases the entry cost of the road (link) in the direction that enters the influence range Sba before the start of the holding time (it is difficult to enter), and the road (link) that exits the influence range Sba. ) To lower the entry cost (easy to get out) and search for a route. Further, the server 400 (route determination unit 102) lowers the entrance cost of the road (link) in the direction entering the influence range Sba after the holding time ends (easy to enter), and the road (link) in the direction from the influence range Sba. ) To increase the entry cost (difficult to come out) and search for a route. These approach costs can be included in the participant behavior prediction information 500 and held.

  According to the above, presenting a route that takes into consideration that the event influence area will be larger than the event range based on the movement of event participants before and after the event start and after the event is over Will be able to. Thereby, even when the user passes the vicinity of the holding range before and after the holding time, the user can efficiently reach the destination while saving time and distance.

  As described above, according to the present invention, it is possible to present a guide route in consideration of the event holding period and the holding range based on the type of event. Thereby, when the event holding range can be passed without congestion, a route that does not avoid the holding range can be presented to the user.

  Further, it is possible to present a route that takes into account that the event influence area becomes larger than the holding range based on the movement of event participants before and after the start of the event.

  In the above embodiment, the user receives the guidance information from the server using the navigation device. However, the guidance information can also be received using another smartphone or the like. In the embodiment, the server performs the route search and the generation of the guidance information. However, the navigation device has the above-described server function without providing the server, and the navigation device generates the route search and the guidance information. And it is good also as a structure which shows to a user.

  The presentation method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
