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

FIG. 1 is a block diagram showing an example of a functional configuration of the presentation device according to the embodiment. The presentation device 100 according to the embodiment includes an acquisition unit 101, a routing 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 of FIG. 1 may be used, or a single client (terminal) may have the function of the presentation device 100 without using the server.

The acquisition unit 101 acquires event information including the type of event, the holding range of the event (the range of influence affecting the route search determination), and the holding time zone. Types of events include, for example, fireworks displays and international soccer games. The range of the event is set by, for example, latitude / longitude, administrative area, etc., and the organizer of the event sets the range around the event location in advance and announces it in advance due to the regulation of road traffic. .. The holding time zone of the event is a date and time and a time zone, and is composed of, for example, a date and a time zone (for example, 16:00 to 18:00, etc.).

The acquisition unit 101 acquires this event information via a network such as the Internet. For example, the acquisition unit 101 acquires the event 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 the information such as the user's current location and destination input from the user's terminal when requesting a route search, the route search (road) from the current location to the destination is performed by referring to the map information (map database). do. At this time, for example, a route with a low search cost (which can be reached in a short time or a distance) is searched based on a cost such as a travel time or a travel distance. At this time, a plurality of routes can be output as candidates in the order of search cost.

Then, when a part of the route searched route passes through a road (evaluation target road) within the holding range within the holding date and time (holding time zone) of the event, 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, at least the holding range is determined as the guide route in the holding time zone of the event after increasing the cost of the evaluation target road. Further, in the case of a certain other event type, the route searched without considering the event information during the holding time zone is determined as the guide route.

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

The route determination unit 102 determines the guidance route when passing through the roads (evaluation target roads) within the holding range inside and outside the event holding time zone based on the participant behavior prediction information (details will be described later) including the event information. Change the content.

Here, it will be described that the congestion state differs depending on the holding time zone and inside and outside the holding time zone due to the different event types.

First, depending on the type of event, cases where the event range can be passed without congestion even within the event time zone and cases where the event cannot be passed will be described. For example, if the event type is a fireworks display, participants are watching fireworks during the holding time, and the movement of participants (cars) within the holding range is small and the congestion within the holding range is low (participants). (Corresponding to the behavior prediction information), the route determination unit 102 determines the route searched for in the holding time zone without considering the event information as the guide route.

On the other hand, outside the holding time zone (pointing to the predetermined period before the start time and the predetermined period after the end time), many participants (cars) move into or out of the holding range (participant behavior prediction information). Therefore, the route determination unit 102 determines as a guide route at least a route that avoids the holding range outside this holding time zone.

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

On the other hand, outside the holding time zone (predetermined period before the start time and predetermined period after the end time), many participants (cars) move into or out of the holding range (participant behavior prediction information). The route determination unit 102 determines as a guide route at least a route that avoids the holding range during the holding time zone.

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

When the route determination unit 102 determines as a guide route a route that passes through or avoids the holding range outside the above-mentioned holding time zone (a predetermined period before the start time and a predetermined period after the end time), the route determination unit 102 refers to the start time zone. The roads within the holding range are divided into multiple time zones (called outside time zones) before and after the start, and based on the stage-specific congestion (participant behavior prediction information) of the outside time zone for each event type. It is possible to change the content of the guidance route when passing through (evaluation target road).

For example, the route determination unit 102 has a large congestion in the outside time zone 1 (less than 1 hour before the start) before the start, a low congestion in the outside time zone 2 (1 hour or more and less than 2 hours before the start), and an outside 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 guidance route when passing through the road (evaluation target road) within the holding range during each outside time zone change.

In addition, the route determination unit 102 uses a setting (participant behavior prediction information) that uniformly increases the passing cost (degree of ease of passage) for all roads (evaluation target roads) within the holding range, and also types of events. Depending on the setting, the amount of increase in the passing cost between the central part and the peripheral part of the holding range may be set differently. For example, in the case of a fireworks display, the central part of the holding range is crowded with participants, so the passing cost is increased because it is difficult to pass, and the peripheral part is easier to pass, so the increased passing cost is reduced.

Further, the route determination unit 102 can change the size of the event holding range according to the type of the event. For example, in the case of a fireworks display, participants are watching fireworks during the holding time, and the movement of participants (cars) within the holding range is small and the congestion within the holding range is low (participant behavior prediction information). ) Therefore, the size of the holding range will not be changed during the holding time zone.

On the other hand, outside the holding time zone (a predetermined period before the start time and a predetermined period after the end time), many participants (cars) move into or out of the holding range, so the predetermined period outside the holding time zone. Makes a change (referred to as an influence range) to expand the holding range (for example, by a predetermined block to the outside). If there is a change in the holding range, the route determination unit 102 considers the changed holding range (influence range) and determines whether or not there is a passage with respect to the influence range as a guide route.

This range of influence is not limited to increasing or decreasing the area (range) based on the holding range, but may include roads (links) leading to a specific highway or expressway leading to the holding range.

Further, the route determination unit 102 may set the approach cost (degree of ease of entry / exit) for each direction of entry / exit to the holding range for each time zone based on the holding time zone of the event whose guidance route has 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 entering direction is high, and because it is easy to leave the holding range, the entry cost in the exit direction is lowered (participation). Person behavior prediction information). The specified period after the end of the event holding time will be the opposite of the cost before the start time.

As described above, the route determination unit 102 determines the guide route by considering the holding range and various costs (participant behavior prediction information) from among the plurality of route candidates initially searched by the route search (evaluation target). The decision is not limited to including or excluding the passage of the road, but the route search may be performed in consideration of the holding range and various costs.

The presentation unit 103 presents the guide route determined by the route determination unit 102. For example, the guidance route can be presented to the user by display or voice. Further, the result (guidance 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 guidance route to the user by display, voice, or the like. be able to.

In the above configuration example, the presentation device 100 is configured by the server and the guidance route is transmitted to the user, but each configuration of the presentation device 100 may be configured by the user's terminal.

FIG. 2 is a flowchart showing an example of a processing procedure of the presentation device according to the embodiment. An example of processing executed by the presenting device 100 when a route search is requested from a user's terminal is shown.

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

Next, the presenting device 100 refers to the map information (map database) based on the information such as the user's current location and destination input when the user's terminal requests the route search, and the route from the current location to the destination. Search the route (road).

Then, when a part of the route searched route passes through a road within the holding range (evaluation target road) within the holding time zone of the event, the presentation device 100 changes the content of the guidance route according to the type of the event. (Step S202). Case 1 is a case where the congestion is small when passing through a road (evaluation target road) within the holding range within the holding time of the event. In this case (step S202: Case1), the presenting device 100 determines the searched route as the guide route without considering the event information (step S203).

Case 2 is a case where it is crowded when passing through a road (evaluation target road) within the holding range within the holding time of the event. In this case (step S202: Case2), the presenting device 100 determines a route avoiding the holding range as a guide route (step S204).

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

Further, although not described in the processing example of FIG. 2, the presentation device 100 also performs a processing of changing the size of the holding range of the event according to the type of the event. For example, in the case of a watching / viewing event during the holding time, the movement of participants (cars) within the influence range where the holding range is changed is small and the congestion within the influence range is small, so during the holding time period, Do not change the size of the affected area. On the other hand, outside the holding time zone (a predetermined period before the start time and a predetermined period after the end time), many participants (cars) move into or out of the influence range, so the predetermined period outside the holding time zone. Makes a change that expands the range of influence (for example, by a predetermined block outward).

According to the above embodiment, when a part of the route obtained by the route search requested by the user passes through the road within the holding range during the holding time zone of the event, the holding range depends on the type of the event. Present a route that passes through the inner road, or present a route that avoids the road within the holding range. Also, whether to present a route that passes through the road within the holding range according to the type of event, not only within the holding time but also outside the holding time (predetermined period before the start time and predetermined period after the end time). Or, it is possible to present a route to avoid the road within the holding range. As a result, it is possible to search for a route according to the type of event, and it is possible to present to the user a route that matches the congestion status of the road within the holding range at the time of holding the event.

For example, if the event type is such that the road within the holding range can easily pass during the holding period, the user can search because the guide route passing through the holding range can be presented and the route avoiding the holding range is not presented. You will be able to reach your destination in less time and distance simply by following the route. As a result, 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 it becomes possible to present a route that considers different holding ranges within (outside) the holding time zone for each event type. Furthermore, depending on the type of event, it will be possible to present a route that takes into consideration the degree of ease of passage in the central and peripheral parts of the holding range within the holding range. It will be possible to present a route that considers the degree of ease of entry and exit for each direction of entry and exit to 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 the server 400 having the function of the presentation device 100 to search for a route, and the server 400 navigates as a response to the route search.

(Hardware configuration of server 400)
FIG. 4 is a block diagram showing an example of the hardware configuration of the server of the embodiment. When the server 400 is used as the presentation device 100, the server 400 has almost the same configuration as that in FIG.

In the case where the server 400 shown in FIG. 4 transmits a guide 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 required for the route search for the server 400. It may be a simple function having only a function of transmitting a route search request such as a destination or a destination and a function of displaying (presenting) a guide route corresponding to the event received from the server 400. Further, even in the case of the configuration in which the navigation device 300 executes the process related to the normal route search, it is possible to receive and display (present) the guide route corresponding to the event without adding any hardware or the like.

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

FIG. 5 is a chart showing an example of participant behavior prediction information held by the server of the embodiment. At the time of route search, the route determination unit 102 determines the above-mentioned guidance route with reference to the participant behavior prediction information 500 shown in FIG. For example, if a route is searched based on the current location and the destination, and there is a route that passes through the holding range at the time of holding the event on this searched route, whether or not to guide this route is determined by the participant behavior prediction information 500. To determine by referring to.

Participant behavior prediction information 500 stored in memory by the route determination unit 102 includes event type 501, which is event information acquired from VICS or the like, and incidental information 502. The accompanying information 502 is the date and time of the event and the road regulation information (closed road, etc.) of 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 routing unit 102 stores and retains the participant behavior prediction information 500.

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 the holding date and time (holding time zone) for each event type consisting of the event type 501 and the accompanying information 502, respectively. It is information which shows the congestion situation of the road (the road to be evaluated) within 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 zone (predetermined period before the starting time) is "smooth (no congestion)". .. In addition, the information of the forecast information 512 during the event indicates that the congestion in the holding range within the holding time zone is "congestion". Further, the post-end prediction information 513 indicates that the congestion in the holding range after the holding time zone (predetermined period after the ending time) is "congestion".

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 the current congestion situations according to the event holding time zone, respectively. The route determination unit 102 acquires and generates a road congestion status transmitted from a vehicle (for example, a navigation device 300 as a probe vehicle) traveling in the event holding range during the event holding time zone (including before and after). do.

Then, when the user requests the route search, the route determination unit 102 includes event information (event type 501 and incidental information 502), pre-start prediction information 511, and in-event prediction information 512 based on the participant behavior prediction information 500. , When a part of the search route passes through the event holding range during the event holding time zone based on any of the information of the post-end prediction information 513, the event passing range is passed as a guidance route presented to the user. Decide whether or not (to avoid).

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

In addition, the congestion time after the start of the event is determined for each event information (event type) 501 according to the size of the holding range, and each period of the pre-start prediction information 511 and the post-end prediction information 513 is 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 is further congested by a plurality of stages of time zones (outside time zones) before and after the start described above. Prediction information may be retained. In addition, for roads within the holding range (evaluation target roads), information on settings (participant behavior prediction information) with uniform passage costs (degree of ease of passage) for each type of event, and the center of the holding range It is possible to hold the information of the setting that the passing cost of the peripheral portion is different from that of the peripheral portion. Further, the information of the influence range in which the size of the event holding range is changed according to the type of the event may be retained. Furthermore, information on the entry cost (degree of ease of entry / exit) for each direction of entry / exit to the holding range for each time zone of the event may be retained.

(Presentation processing of guidance information by the server)
FIG. 6 is a diagram illustrating a process of presenting guidance information by a system including a server and a navigation device of an embodiment. The server 400 collects event information performed in each region A to n. The size of each region A to n is set according to the holding range of the event, and is set at least in a range larger than the holding range Sa of the event.

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

Further, the acquisition unit 101 of the server 400 communicates with VICS (information center) 601 or the like to acquire event information.

The route determination unit 102 of the server 400 has a database 102a, and collects the congestion status for each region A to n acquired from each vehicle 602 for each event holding time and stores it in the database 102a. Then, the server 400 generates the participant behavior prediction information 500 based on the event information for each event and the congestion status for each region A to n, and stores the participant behavior prediction information 500 in the database 102a.

As a result, the database 102a stores and holds the participant behavior prediction information 500 for each event held in the past, and the participant behavior prediction information 500 that reflects the latest congestion status of the event currently being held is stored. It will be stored.

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

Then, when a part of the route of the vehicle 612 passes through an event (event holding range Sb in region B in the example of FIG. 6) when the route is searched by the route determination unit 102, 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 is transmitted to the navigation device 300 of the vehicle 612. As described above, the guide route R may be a route that passes through the event holding range or a route that avoids the event.

The navigation device 300 of the vehicle 612 presents the guidance route R transmitted from the server 400 to the user by display or the like. As a result, the user is affected by the traffic congestion caused by the event by traveling according to the guidance route R presented by the server 400 without considering the event holding range and holding time when requesting the route search. You will be able to drive to your destination without having to.

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

At the time of route search, the server 400 (route determination unit 102) acquires the road congestion status in the event holding range from VICS (information center) 601 and vehicles near the event holding range, and participates in the corresponding event. The behavior prediction information 500 is generated. Then, the server 400 determines the congestion status of the road (evaluation target road) within the holding range of the event when passing through the searched route based on the participant behavior prediction information 500. 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 out of the congestion range or outside the congestion time zone. It is determined whether or not there is (step S702).

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

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

When 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, so that the cost of the road to be evaluated due to the event holding The route is searched without making any changes (step S704).

On the other hand, when 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, so that the evaluation target road accompanying the event holding The cost is increased according to the degree of congestion (step S705), and the route search according to 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 reaches the destination (step S706: Yes), the server 400 (route determination unit 102) evaluates the cost of the entire searched route (step S708) and ends the route search (step S709). .. As described above, the server 400 (route determination unit 102) presents the searched route to the user as the guide route R. At this time, the server 400 transmits the guidance route R to the user's navigation device 300 by communication, and the navigation device 300 presents the received guidance route R to the user by display or the like. If 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 guidance 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 guidance route R by time and distance from the route candidates. be able to.

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

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

As a result, during the event holding period, the route for avoiding the event holding range Sb has been conventionally guided, but for example, as shown in FIG. 8, based on the event holding time and passing time. , The route passing through the event holding range Sb during the holding period of the event can be presented to the user as the guide route R. In this case, the user can efficiently reach the destination by 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 guide route R in more detail by 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 is large, and the congestion of the outside time zone 2 (1 hour or more and less than 2 hours before the start) is small. If there is information that there is no congestion (smooth) in the outside time zone 3 (2 hours or more before the start), refer to this and when passing through the road (evaluation target road) within the holding range in each outside time zone The content of the guidance route R can be changed.

Further, the server 400 (route determination unit 102) sets the passage cost of all the roads within the holding range (evaluation target roads) to be uniform for each event type as other information stored in the participant behavior prediction information 500. , The content of the guidance route R when passing through the road (evaluation target road) within the holding range can be changed by referring to the setting that the passing cost is different between the central part and the peripheral part of the holding range.

FIG. 9 is a diagram showing another presentation example of the guidance information according to the embodiment. In the above embodiment, as shown in FIG. 8, as for the holding range of the event, the holding range acquired from VICS (Information Center) 601 or the like is used as it is and presented to the user. In the example shown in FIG. 9, not only the event holding range Sb but also the influence range Sba, which is a congestion occurrence prediction area that changes every time the event is held, is displayed. For example, the holding range Sb and the influence range Sba may be displayed at the same time by changing the display color or changing the transparency of the display.

The event is based on the holding time, and the congestion occurrence prediction area Sba changes depending on the participants entering and leaving the holding range Sb. In the example shown in FIG. 9, it is the case of the current time (16:10) immediately after the event holding time (end time 16:00). In this way, at the time immediately after the event is finished, 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 predetermined block (for example, one block) wider than the event holding range Sb as the influence range Sba which means the congestion occurrence prediction area.

The server 400 holds the information of the influence range as the incidental 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 the evaluation target road at the time of route search. As a result, conventionally, a route for avoiding only the event holding range Sb has been guided, but according to the embodiment, the event is based on the holding time and the passing time of the event, as shown in the example of FIG. It is decided whether or not to pass the route included in the influence range Sba before and after the holding period of.

In addition, many participants enter the holding range Sb before the start of the event based on the holding time of the event, and many participants leave the holding range Sb after the event ends. For example, the server 400 (route determination unit 102) increases the entry cost (difficult to enter) of the road (link) in the direction of entering the influence range Sba before the start of the holding time, and increases the entry cost (difficult to enter) of the road (link) in the direction of exiting the influence range Sba. ) Lower the entry cost (easy to get out) and search for a route. Further, the server 400 (route determination unit 102) lowers the entry cost (easy to enter) of the road (link) in the direction of entering the influence range Sba after the end of the holding time, and the road (link) in the direction of exiting the influence range Sba. ) Increase the entry cost (difficult to get out) and search for a route. These entry costs can be included in the participant behavior prediction information 500 and retained.

According to the above, it is necessary to present a route that takes into consideration that the affected area of the event will be larger than the holding range based on the movement of event participants before and after the event starts and after the event is held and outside the holding period. Will be able to. As a result, the user can efficiently reach the destination by saving time and distance even when passing near the holding range before and after the holding time.

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

In addition, it will be possible to present a route that takes into consideration that the affected area of the event will be larger than the holding range based on the movement of the event participants before the start of the event and after the end of the event.

Further, in the above embodiment, the user receives the guidance information from the server using the navigation device, but the guidance information can also be received by using another smartphone or the like. Further, in the embodiment, the server is configured to perform the route search and the generation of the guidance information, but the navigation device has the above-mentioned server function without providing the server, and the navigation device performs the route search and the generation of the guidance information. And may be configured to present to the 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 executed by being recorded on a computer-readable recording medium such as a hard disk, flexible disk, CD-ROM, MO, or DVD, and read from the recording medium by the computer. Further, this program may be a transmission medium that can be distributed via a network such as the Internet.
