The destination means 11 calculates a travel time along a retrieved route from a current place to the destination and a travel time along a route from the destination to the scheduled place and determines whether the user can arrive in the scheduled time even when stopping by the destination on the basis of the travel time to the destination and the travel time from the destination to the scheduled place.

Description

  The present invention relates to a schedule support system that performs notification / suggestion based on a preset schedule.

  In recent years, various types of driving assistance have been realized, one of which is a navigation function for guiding a route to a destination. The navigation function is not limited to in-vehicle devices, and can be used on mobile terminals such as smartphones and tablets.

  Conventionally, as a navigation function, an apparatus for monitoring a movement state with respect to a movement plan set by a traveler has been disclosed (for example, see Patent Document 1). In this device, a traveler's allowable arrival time is held for each destination, and deviation from the travel plan is determined based on the allowable arrival time.

Japanese Patent No. 3232967

  By the way, recently, schedules of users such as meetings have been unified through cloud computing (network) in PCs, smartphones, tablets, in-vehicle navigation devices, and the like. Therefore, it is conceivable to provide guidance according to the schedule on the assumption that the schedule includes information such as location and date / time.

  However, if the conventional technology is applied as it is, the technology is merely related to the movement to the place on the schedule (hereinafter referred to as “schedule place”), and at the time already scheduled at the time of starting the movement (hereinafter referred to as “schedule time”). It may not be in time. In other words, it is important to pay attention to actions before the schedule in order to provide guidance according to the schedule.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a schedule support system capable of supporting the achievement of the schedule in consideration of the user's behavior before the schedule. is there.

  In the schedule support system (1) of the present invention made to achieve the above object, a schedule for each user is stored in the schedule storage unit (21). The schedule includes a schedule location that is a scheduled location and a schedule time that is a scheduled time. The schedule time is generally composed of date and time information. Of course, when only the schedule of the day is targeted, it may be configured only with time information.

  For example, the schedule support system may be composed of a center (3) and a terminal device (5). This is because it is conceivable to store the schedule in the center when using cloud computing. On the other hand, information input from the user and information output to the user are performed via the terminal device. However, the terminal device may include the schedule storage unit, and the invention may be realized by the terminal device alone.

  In the present invention, when a new destination prior to the schedule is set, the determination means (11) determines whether the schedule time is in time even after passing through the destination, and based on the determination result, Notification by the notification means (12) is performed.

  In this way, it is possible to support the achievement of the schedule in consideration of the user's behavior before the schedule.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the schedule support system 1 of the present embodiment includes a center 3 and a terminal device 5.

  The center 3 is configured around the processing execution unit 10. The processing execution unit 10 is a so-called computer that includes a CPU, ROM, RAM, I / O, and a bus line connecting them. The processing execution unit 10 includes a schedule storage unit 21, a map information storage unit 22, a traffic information storage unit 23, a facility information storage unit 24, a general-purpose storage unit 25, and a center side interface (hereinafter “center side I / F”). 26) is connected.

  Each of the storage units 21 to 25 is configured to store information, and is embodied as, for example, a hard disk drive (HDD). Of course, although the memory | storage parts 21-25 were divided and illustrated, you may make it memorize | store various information in one memory | storage device.

  The schedule storage unit 21 stores a user's schedule. This schedule includes personal identification information, and also includes schedule location, schedule time, and contact information for schedule adjustment. This schedule is transmitted from the terminal device 5 and stored. As will be described later, a destination or the like is also input from the terminal device 5, but a terminal device for inputting a schedule and a terminal device for inputting a destination or the like may be configured separately. For example, a terminal device for inputting a schedule is an office PC, and a terminal device for inputting a destination or the like is a navigation device mounted on a vehicle.

  The map information storage unit 22 stores map data. This map data is the same as that used in conventional navigation devices, and includes road data, map matching data, guidance data, and the like. Based on this map data, the process execution unit 10 calculates a route search and a travel time of the searched route.

  The traffic information storage unit 23 stores traffic information that changes every moment. The traffic information includes traffic jam information, accident information, regulation information, and the like. The processing execution unit 10 can recalculate the travel time of the searched route based on the traffic information.

The facility information storage unit 24 stores facility information related to various facilities. The facility information includes the type of facility, and a facility that is an alternative candidate can be searched as will be described later.
The general-purpose storage unit 25 is configured to store, for example, a set destination or a temporary calculation result.

The center side I / F 26 is configured to perform data communication with the terminal device 5. Data communication with the terminal device 5 is performed through a wireless line.
The terminal device 5 is configured to be capable of data communication with the center 3 described above. The terminal device 5 is embodied as, for example, a smartphone, a tablet, a notebook PC, an in-vehicle navigation device, or the like. Smartphones and tablets are not limited to being mounted on vehicles, but can also be used on public transportation or on foot.

  The terminal device 5 is configured around the control unit 31. The control unit 31 is a so-called computer including a CPU, a ROM, a RAM, an I / O, and a bus line connecting them. A terminal-side interface (hereinafter referred to as “terminal-side I / F”) 32, an input unit 33, and a display unit 34 are connected to the control unit 31.

The terminal-side I / F 32 is configured to perform data communication with the center 3, and data communication via the network is performed via the center-side I / F 26 of the center 3.
The input unit 33 is a configuration for a user to input information, and is embodied as a physical push button switch. When the terminal device 5 is a smartphone or a tablet, the touch panel is configured integrally with the display unit 34.

The display unit 34 is a configuration for informing the user of information, and is generally considered to be configured by a color liquid crystal display device.
Next, the notification process will be described based on the flowcharts of FIGS. This notification process is repeatedly executed at predetermined time intervals by the process execution unit 10 of the center 3.

In the first S100, the current date and time are acquired. This current date and time is a starting point for calculating the arrival time at the schedule location.
In subsequent S110, it is determined whether or not there is a destination setting request. When a destination is set via the input unit 33 of the terminal device 5 due to the start of the navigation function in the terminal device 5, a destination and destination setting request is transmitted from the terminal side I / F 32 to the center 3. The center 3 receives the destination and the destination setting request via the center side I / F 26. If it is determined that there is a destination setting request (S110: YES), the process proceeds to S120. On the other hand, when it is determined that there is no destination setting request (S110: NO), the subsequent processing is not executed and the notification processing is terminated.

In the next S120, the destination is stored. In this process, the destination transmitted from the terminal device 5 is stored in the general-purpose storage unit 25.
In subsequent S130, a route search to the destination is performed. This process searches for the route to the destination stored in S120, and is performed based on the map data in the map information storage unit 22.

  In the next S140, the travel time to the destination is calculated. This process calculates the travel time when moving to the destination along the route searched in S130. The travel time is also calculated based on the map data in the map information storage unit 22.

  In subsequent S150, the required achievement time is estimated. This process estimates the time required for the user to complete the business at the destination. For example, in the case of a shopping center, it may be possible to set a required time for each facility such as 1 hour and store it in the facility information storage unit 24. Further, for example, it is conceivable to store the required time averaged by probing the past facility usage time for each user in the facility information storage unit 24.

  In next S160, the schedule is searched. This process searches the schedule storage unit 21 for the future schedule that is closest to the present time. When the schedule is clogged and the schedule is set continuously, it is presumed that the movement from the first schedule location to the next schedule location is usually set so as to be movable with time. Therefore, the schedule targeted in the notification process is the future schedule closest to the present time.

  In subsequent S170, it is determined whether there is a target schedule. If it is determined that there is a schedule (S170: YES), the process proceeds to S180 in FIG. On the other hand, if it is determined that there is no schedule (S170: NO), the subsequent processing is not executed and the notification processing is terminated.

  In S180, which is shifted to when it is determined that there is a schedule, a route search to the schedule location is performed. This process searches for a route from the destination to the schedule location searched in S160.

  In subsequent S190, the travel time to the schedule location is calculated. This process calculates the travel time when traveling from the destination to the scheduled location along the route searched in S180.

In the next S200, the schedule time is acquired. The schedule time is composed of a date and time, and is stored in the schedule storage unit 21.
In continuing S210, it is judged whether it is in time for schedule time. In this process, it is determined whether or not the sum of the travel time from the current location to the destination and the travel time from the destination to the schedule location plus the current time does not exceed the schedule time. If it is determined that the scheduled time is in time (S210: YES), the process proceeds to S230. On the other hand, when it is determined that it is not in time for the schedule time (S210: NO), the notification level 1 is stored in the general-purpose storage unit 25 in S220, and then the process proceeds to S250.

  In S230, it is determined whether the scheduled time including the required achievement time is in time. This process determines whether or not the travel time from the current location to the destination, the achievement time at the destination, and the travel time from the destination to the scheduled location plus the current time does not exceed the scheduled time. Judgment. If it is determined that the scheduled time including the required achievement time is in time (S230: YES), the notification process is terminated without executing the subsequent processes. On the other hand, if it is determined that the required achievement time is included, the schedule time is not met (S230: NO), the notification level 2 is stored in the general-purpose storage unit 25, and then the process proceeds to S250.

  In S250, a notification instruction according to the notification level is performed. Notification level 1 is a case where only the travel time is taken into account and the schedule time is not met, for example, “If you move to the destination you set this time, you may not be in time for the next XX schedule”. It is possible to do it. In addition, the notification level 2 is a case where the scheduled time is not in time if the required achievement time is included. For example, “There is a schedule for the next XX, so the time for implementing the purpose of the required □□ at the destination set this time. May be only about ΔΔ minutes ”. Note that a notification instruction is transmitted from the center 3 to the terminal device 5, whereby notification to the user is performed via the display unit 34 of the terminal device 5.

Next, the alternative guidance process will be described based on the flowcharts of FIGS. This alternative guidance process is executed by the process execution unit 10 of the center 3 following the above-described notification process.
In first S300, it is determined whether or not there is a notification level. This process corresponds to S220 and S240 in FIG. 3, and when the notification level 1 or 2 is stored in the general-purpose storage unit 25, an affirmative determination is made. If it is determined that there is a notification level (S300: YES), the process proceeds to S310. On the other hand, when it is determined that there is no notification level (S300: NO), the subsequent processing is terminated without executing the subsequent processing.

  In S310, an alternative candidate facility is searched. This process searches for facilities that can be alternative candidates from the facility information stored in the facility information storage unit 24. Assuming that there are a plurality of alternative candidate facilities, a search is performed from facilities close to the route along the route from the current location to the schedule location. If the route goes through an alternative facility, the travel time will be shorter.

  In subsequent S320, it is determined whether or not an end condition is satisfied. Here, an affirmative determination is made when all the facilities that can be candidates for the route are searched or when a necessary number of facilities are found. If it is determined that the end condition is satisfied (S320: YES), the process proceeds to S390. On the other hand, when it is determined that the termination condition is not satisfied (S320: NO), the process proceeds to S330.

  In S330, one facility near the route along the route searched in S310 is acquired as an alternative candidate facility. Next, when S330 is executed, one facility closest to the next is acquired.

  In subsequent S340, it is determined whether or not the facilities are of the same type. The purpose of determining whether or not the facility is the same type of facility is that if the destination is originally a shopping center, the facility for shopping is searched for the purpose of shopping. This process determines whether or not the type of alternative candidate facility acquired in S330 is the same as the destination facility type. If it is determined that the facility types are the same (S340: YES), the process proceeds to S350. On the other hand, when it is determined that the facility types are not the same (S340: NO), the processing from S320 is repeated. In the present embodiment, a facility having the same type as the destination facility is determined. Of course, alternative facility types that can be substituted for each facility type may be prepared in advance in a table or the like. .

  In S350, the route to the alternative candidate facility is searched. This process searches for a route from the current location to the alternative candidate facility acquired in S330, and is performed based on the map data in the map information storage unit 22.

  In subsequent S360, the travel time to the alternative candidate facility is calculated. This process calculates the travel time when traveling to the alternative candidate facility along the route searched in S350. The travel time is also calculated based on the map data in the map information storage unit 22.

In the next S370, the route to the schedule location is searched. This process searches for a route from the alternative candidate facility to the schedule location.
In subsequent S380, the travel time to the schedule location is calculated. This process calculates the travel time when traveling from the alternative candidate facility to the schedule location along the route searched in S370. After the process of S380 is completed, the process proceeds to S410 in FIG.

  In S410, when passing through the alternative candidate facility, it is determined whether the scheduled time including the required achievement time is in time. In this process, whether the travel time from the current location to the alternative candidate facility, the achievement time at the alternative candidate facility, and the travel time from the alternative candidate facility to the schedule location, plus the current time, does not exceed the schedule time. It is to judge whether or not. When it is determined that the scheduled time including the required achievement time is in time (S410: YES), the substitute level A is stored in the general-purpose storage unit 25, and then the processing from S320 in FIG. 4 is repeated. On the other hand, if it is determined that the scheduled achievement time is not included when the required achievement time is included (S410: NO), the process proceeds to S430.

  In S430, it is determined whether or not the schedule time is met. This process is to determine whether or not the travel time from the current location to the alternative candidate facility and the travel time from the alternative candidate facility to the schedule location plus the current time does not exceed the schedule time. If it is determined that it is in time for the schedule time (S430: YES), it is stored in the general-purpose storage unit 25 as an alternative level B in S440, and then the processing from S320 in FIG. 4 is repeated. On the other hand, when it is determined that the schedule time is not met (S210: NO), the process proceeds to S390 in FIG. This is because when it is determined that the travel time alone is not in time, it is not necessary to consider the next facility further away from the route.

  When an affirmative determination is made in S320 in FIG. 4 or a negative determination is made in S430 in FIG. 5, the process proceeds to S390 in FIG. 4 to determine whether there is an alternative candidate facility. If there is no facility that can be an alternative candidate, a negative determination is made. If it is determined that there is an alternative candidate facility (S390: YES), an instruction to display the alternative candidate facility is issued in S400, and then the alternative guidance process ends. On the other hand, if it is determined that there is no alternative candidate facility (S390: NO), the process of S400 is not executed and the alternative guidance process is terminated.

  In S400, an alternative candidate facility is displayed on the display unit 34 of the terminal device 5 by transmitting a display instruction from the center 3 to the terminal device 5. In addition, the facility memorized as alternative level A is a facility that does not affect the next schedule and is displayed as a facility that has time to achieve the purpose of □□ at the destination that was initially set. . About facilities memorized as substitution level B, it is a facility that does not affect the next schedule, but it can secure about ▽▽ minutes to achieve the purpose of □□ at the destination that was initially set Display as a facility.

Next, the adjustment process will be described based on the flowchart of FIG. This adjustment process is executed by the process execution unit 10 of the center 3 following the above-described alternative guidance process.
In the first S500, it is determined whether or not a proposal for an alternative candidate facility has been accepted. This determination is affirmative when the user selects an alternative candidate facility as a destination via the input unit 33 after the alternative candidate facility is displayed in S400 in FIG. If it is determined that the alternative candidate facility has been accepted (S500: YES), route guidance to the alternative candidate facility is performed in S580, and then the adjustment process is terminated. On the other hand, when it is determined that the alternative candidate facility has not been accepted (S500: NO), the process proceeds to S510.

  In S510, route guidance to the destination is performed. This process performs route guidance to the set initial destination. This is because, by not accepting the proposal of the alternative candidate facility, it is considered that the movement to the destination is given priority over the next schedule for the user.

In subsequent S520, contact information is acquired. In this process, for example, information on the contact information of the person in charge of adjustment is acquired. Contact information is stored in the schedule storage unit 21.
In the next S530, an adjustment method is proposed. This process uses the contact information acquired in step S520 to propose a method for contacting. For example, it suggests whether you want to contact us by phone or email. Such a proposal is displayed on the display unit 34 of the terminal device 5 based on information from the center 3. When the user selects an adjustment method via the input unit 33, for example, a notification that the schedule is delayed is made. This communication may be performed automatically or manually. In the situation where the vehicle is moving, the former is effective.

  In subsequent S540, the adjustment result is acquired. For example, it is conceivable that the adjustment result confirms that the schedule is delayed, or delays the schedule time, for example.

  In the next S550, the development destination is searched. Deployment destinations are people other than the contact information acquired in S520, who need to be contacted. This expansion destination is also included in the contact information.

  In subsequent S560, it is determined whether there is a development destination. If it is determined that there is a deployment destination (S560: YES), a deployment method is proposed in S570, and then the adjustment process is terminated. The proposal of the expansion method is the same as the proposal of the adjustment method. On the other hand, when it is determined that there is no expansion destination (S560: NO), the process of S570 is not executed and the adjustment process is terminated.

Next, in order to facilitate understanding of the above-described notification process and alternative guidance process, a specific description will be added using FIG.
In the notification process, as shown in FIG. 7, a route R1 to the destination is searched (S130 in FIG. 2), and a travel time T1 to the destination is calculated (S140). Further, the required achievement time T2 at the destination is estimated (S150). Further, a future schedule closest to the present time is searched (S160), and if there is a schedule (S170: YES), a route R2 to the schedule location is searched (S180 in FIG. 3), and a travel time T3 is calculated ( S190). Then, it is determined whether or not the sum of the travel time T1 from the current location to the destination and the travel time T3 from the destination to the schedule location plus the current time does not exceed the schedule time (S210). Here, when it is not in time for the schedule (S210: NO), a notification instruction is given as notification level 1 (S220, S250). If it is in time for the schedule (S210: YES), the travel time T1 from the current location to the destination, the achievement time T2 at the destination, and the travel time T3 from the destination to the schedule location added to the current time However, it is determined whether or not the scheduled time is exceeded (S230). Here, if it is determined that the required achievement time T2 is included and the schedule time is not met (S230: NO), a notification instruction is given as notification level 2 (S240, S250).

  In the alternative guidance process, a facility near the route is searched (S310 in FIG. 4). When a plurality of alternative candidate facilities are searched, the facilities are sorted in order from the facility closest to the route along the route from the current location to the schedule location. In FIG. 7, the alternative candidate facility X, the alternative candidate facility Y, and the alternative candidate facility Z are rearranged in this order. If the alternative candidate facility X is of the same type as the destination (S340: YES), the route R3 to the alternative candidate facility X is searched (S350), and the travel time T4 to the alternative candidate facility X is calculated (S360). ). Further, the route R4 from the alternative candidate facility to the schedule location is searched (S370), and the travel time T5 to the schedule location is calculated (S380). Then, the travel time T4 from the current location to the alternative candidate facility, the achievement achievement time T2 at the alternative candidate facility, and the travel time T5 from the alternative candidate facility to the schedule location plus the current time do not exceed the schedule time. Is determined (S410 in FIG. 5). When it is determined that the schedule including the required achievement time T2 is in time (S410: YES), the substitute level A is set. If it is determined that the scheduled achievement time T2 is not included when including the required achievement time T2 (S410: NO), the travel time T4 from the current location to the alternative candidate facility A and the travel time T5 from the alternative candidate facility to the schedule location are currently It is determined whether the time added does not exceed the schedule time (S430). If it is determined that the schedule time is reached (S430: YES), the substitute level B is set.

  Similarly, when the same processing is performed in the order of the alternative candidate facility Y → the alternative candidate facility Z →..., The processing is performed for all the alternative candidate facilities, or the necessary number of alternative candidate facilities is found (S320: YES), an instruction to display alternative candidate facilities is given in accordance with the alternative level (S400).

  As described above in detail, in the present embodiment, the schedule storage unit 21 stores a schedule for each user. This schedule includes personal identification information, and also includes schedule location, schedule time, and contact information for schedule adjustment.

  Then, when there is a destination setting request (S110: YES in FIG. 2), the center 3 stores the destination (S120) and determines whether or not it is in time for the schedule even after passing through the destination (S210). , S230). The notification level is stored according to the determination result (S220, S240), and notification based on this is instructed (S250).

  That is, when a schedule location that is a scheduled location and a schedule storage unit 21 that stores a schedule including a schedule time that is a scheduled time for each user, and a new destination prior to the schedule is set, A determination unit 11 that determines whether the scheduled time is in time even after passing through the destination, and a notification unit 12 that performs notification based on a determination result by the determination unit 11 are provided.

Accordingly, it is possible to support the achievement of the schedule in consideration of the user's behavior before the schedule.
Specifically, after storing the destination (S120 in FIG. 2), the route to the destination is searched (S130), and the travel time to the destination is calculated (S140). If the schedule exists (S170: YES), the route from the destination to the schedule location is searched (S180 in FIG. 3), and the travel time to the schedule location is calculated (S190). Then, it is determined whether or not the travel time from the current location to the destination and the travel time from the destination to the schedule location plus the current time does not exceed the schedule time (S210). That is, the judging means 11 calculates the travel time along the route searched from the current location to the destination, calculates the travel time along the route from the destination to the schedule location, and calculates the travel time to the destination and the destination. Based on the travel time from the ground to the schedule location, it is determined whether or not the schedule time can be met even after passing through the destination. Thereby, it is possible to support the achievement of the schedule in a relatively simple manner in consideration of the user's behavior before the schedule.

  Also, the required achievement time at the destination is estimated (S150 in FIG. 2), and the travel time from the current location to the destination, the required achievement time at the destination, and the travel time from the destination to the scheduled location are currently calculated. It is determined whether the time added does not exceed the schedule time (S230 in FIG. 3). That is, the judging means 11 estimates the required achievement time required to achieve the purpose at the destination, and based on the travel time to the destination, the travel time from the destination to the scheduled place, and the desired achievement time, Even if the job is achieved on the ground, it is determined whether or not it is in time for the scheduled time. Thus, the achievement of the schedule can be supported in consideration of the user's behavior before the schedule including the required achievement time at the destination.

  In the present embodiment, when the schedule is affected (S300 in FIG. 4: YES), the facility information stored in the facility information storage unit 24 is searched for a facility that can be a replacement candidate (S310), and each replacement is performed. It is determined whether or not the candidate facility is in time for the schedule time even after passing through the alternative candidate facility (S430 in FIG. 5). Then, an instruction to display an alternative candidate facility in time for the schedule time is given (S400 in FIG. 4), and a proposal is made to the user via the terminal device 5. That is, when the determination unit 11 determines that the schedule time is affected, the search unit 13 searches for an alternative candidate facility that may be an alternative candidate for the destination, and is searched by the search unit 13. The alternative determination means 14 for determining whether the schedule time is met even after passing through the alternative candidate facility, and the suggestion means 15 for proposing an alternative candidate facility based on the determination result by the alternative determination means 14. . As a result, an alternative candidate facility that is in time for the schedule is proposed, so the effect of schedule achievement support stands out.

  Specifically, the route to the alternative candidate facility is searched (S350 in FIG. 4), and the travel time to the alternative candidate facility is calculated (S360). Further, the route from the alternative candidate facility to the schedule location is searched (S370), and the travel time from the alternative candidate facility to the schedule location is calculated (S380). Then, it is determined whether the travel time from the current location to the alternative candidate facility and the travel time from the alternative candidate facility to the schedule location plus the current time does not exceed the schedule time (S430 in FIG. 5). ). In other words, the alternative determination unit 14 calculates the travel time along the route from the current location to the alternative candidate facility, and calculates the travel time along the route from the alternative candidate facility to the schedule location. Based on the travel time and the travel time from the alternative candidate facility to the schedule location, it is determined whether or not the schedule time can be met even after passing through the alternative candidate facility. As a result, an alternative candidate facility that is in time for the schedule is proposed, so the effect of schedule achievement support stands out.

  Further, it is determined whether or not the retrieved alternative candidate facility is the same type of facility as the destination (S340 in FIG. 4), the travel time from the current location to the alternative candidate facility, the travel time from the alternative candidate facility to the schedule location Then, it is determined whether or not the required achievement time added to the current time does not exceed the schedule time (S410 in FIG. 5). That is, the alternative determination means 14 determines an alternative candidate facility that is estimated to be able to achieve the use at the destination, and also travels to the alternative candidate facility, travel time from the alternative candidate facility to the schedule location, and achieves the use. Based on the time, it is judged whether or not the schedule time can be met even if the replacement candidate facility is achieved. As a result, an alternative candidate facility that is in time for the schedule including the required achievement time in the alternative candidate facility is proposed, so that the effect of schedule achievement support stands out.

  Furthermore, in this embodiment, when a user accepts a proposal for an alternative candidate facility (S500 in FIG. 6: YES), route guidance to the alternative candidate facility is performed (S580), and an alternative candidate facility proposal is accepted. If not (S500: NO), route guidance to the initial destination is performed (S510). In other words, when the alternative candidate facility proposed by the proposing means 15 is selected by the user, guidance is provided to the alternative candidate facility, and when the alternative candidate facility is not selected by the user, guidance is provided to the destination. Means 16 are further provided. Thereby, even if a schedule exists, it is possible to provide support that respects the user's intention.

  Then, when performing route guidance to the destination, it will not be in time for the schedule, so contact information is acquired (S520 in FIG. 6), and contact with related parties by phone or e-mail is semi-automatically performed. (S530 to S570). That is, the schedule includes contact information, and when the alternative candidate facility is not selected by the user, the schedule is provided with a contact means 17 that notifies that the schedule time is not met based on the contact information. As a result, sufficient care is taken when it is difficult to achieve the schedule.

As described above, the present invention is not limited to the embodiment described above, and can be implemented in various forms without departing from the technical scope thereof.
(A) In the above-described embodiment, the notification process, the alternative guidance process, and the adjustment process are executed at the time of departure with the first departure point as the current location. On the other hand, the traffic information that changes from moment to moment may be read from the traffic information storage unit 23, and the same processing as in the above embodiment may be performed during the movement. In this way, it is possible to deal with traffic information that changes from time to time, and a more detailed service is realized.

  (B) In the above embodiment, the center 3 executes each process. However, the terminal device 5 may execute a part or all of the processes. Even if it does in this way, the same effect as the above-mentioned embodiment is produced.

  (C) In the above embodiment, the target schedule in the notification process is the future schedule closest to the present time. On the other hand, the same processing may be performed for the second, third,... Schedules. For example, when it is not in time for the first schedule, it may be notified that the second schedule is in time.
