Description

  The present invention relates to a portable terminal, a guidance display system, and a program for guiding an optimum route from a user's current position to a destination.

  In recent years, for example, a technique for guiding an optimal route to a destination designated by a user is known.

  For example, there has been proposed an apparatus (system) called an intelligent passenger assistance apparatus that guides a user (railway user) including seat reservation. According to this device, for example, by registering in advance the time for the user to walk to the station, the home departure time can be presented from the walking time and the departure time of the train.

  In addition, for example, when a user who is a pedestrian walks to a transportation boarding point that he / she wants to use and walks from a destination point of transportation to a destination point, the user only specifies the destination point. Thus, a technique (hereinafter referred to as Prior Art 1) for searching for a route with the lowest cost including a walking section is disclosed (see, for example, Patent Document 1). According to this prior art 1, the optimum route is calculated by comparing the distances from the departure point of the user to a plurality of stations and selecting the optimal boarding station from the plurality of stations.

Also, for example, by acquiring the current position information of the mobile terminal used by the user, calculating the estimated arrival time by searching for the route from the current position to various facilities, and setting the cancellation time based on that, it is possible to accurately A technique that enables reservation and cancellation (hereinafter referred to as Prior Art 2) is disclosed (for example, see Patent Document 2).
JP 2000-258184 A JP 2006-268720 A

  However, in the above-described intelligent passenger assistance device, since the walking time is registered in advance, it is not possible to provide a flexible service such as changing the train used by the user according to the user's walking situation, for example. .

  In the above-described prior art 1, for example, it is possible to statically select an optimal boarding station, but guidance on which train the user should use at the selected station, for example, which train can be used, etc. I can't do it. Moreover, in prior art 1, an optimal boarding station cannot be selected according to a user's walking speed etc., for example.

  In the above prior art 2, the estimated arrival time is calculated using the current position of the user, the map information, and the time information of the transportation, and therefore, for example, the arrival time based on the walking speed of the user cannot be calculated. .

  Further, for example, in a system for navigating to a boarding station where a user gets on a train, only the one that handles the boarding station as a point is known, and when the user gets on from a station on which a plurality of routes get on, the user Nothing is known to guide you from where you can get on.

  Accordingly, an object of the present invention is to provide a portable terminal, a guidance display system, and a program that can perform optimum route guidance to a destination by accurately predicting the time of arrival at a station to be used by a user. There is to do.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram mainly showing a functional configuration of the mobile terminal according to the present embodiment. This portable terminal is held by a user and has a communication function for performing communication via a network, for example.

  A mobile terminal 10 shown in FIG. 1 includes an input unit 11, a position detection unit 12, a boarding station route calculation unit 13, a movement speed calculation unit 14, a movement history storage unit (first storage means) 15, and a section storage unit (second storage). Storage means) 16, arrival time calculation unit 17, transit route calculation unit 18, and guidance display unit 19.

  In the present embodiment, the input unit 11, the position detection unit 12, the boarding station route calculation unit 13, the moving speed calculation unit 14, the arrival time calculation unit 17, the connection route calculation unit 18, and the guidance display unit 19 are connected to the mobile terminal 10, for example. It is assumed that the program stored in a memory (not shown) that is configured is executed by a computer (not shown) of the mobile terminal 10 executing the program. This program can be stored in advance in a computer-readable storage medium and distributed. Moreover, this program may be downloaded to the portable terminal 10 via a network.

  In the present embodiment, the movement history storage unit 15 and the section storage unit 16 are stored in the memory that configures the mobile terminal 10 described above, for example.

  The input unit 11 inputs destination information indicating a destination designated by a user who holds (uses) the mobile terminal 10. The input unit 11 inputs priority item information indicating priority items including, for example, the required time to the destination designated by the user, the fare or the number of transfers. The priority item is an item that is prioritized when, for example, a transit route described later is acquired. That is, for example, when the required time is specified as a priority item, a transit route with a short required time is preferentially acquired.

  The priority items may include, for example, the number of steps for transfer or the moving distance when transferring. The user can specify a destination, a priority item, and the like by operating the mobile terminal 10. Note that the destination specified by the user includes, for example, a station or a location such as an address.

  The position detection unit 12 receives, for example, position information indicating the current position of the mobile terminal 10 by radio waves from GPS (Global Positioning System) hygiene, thereby periodically determining the current position of the user who holds the mobile terminal 10 and moves. Detect. For example, when the destination information is input by the input unit 11, the position detection unit 12 periodically detects the current position of the user. The user holding the mobile terminal 10 moves by walking, for example. Note that the user may move by, for example, a bicycle or a wheelchair.

  The boarding station route calculation unit 13 acquires map information indicating a map around the current position detected by the position detection unit 12 from the outside of the mobile terminal 10. In this case, the boarding station route calculation part 13 receives map information via a network, for example. The boarding station route calculation unit 13 is used to arrive at the destination indicated by the destination information input by the input unit 11 based on the current position detected by the position detection unit 12 and the acquired map information. Determine the station (hereinafter referred to as the boarding station). In the present embodiment, for example, when there are a plurality of routes even at the same station, it is handled as a different boarding station for each route.

  At this time, the boarding station route calculation unit 13 determines the boarding station based on, for example, the first rule or the second rule. In the first rule, for example, a station that is close to the current position detected by the position detection unit 12 is determined as a boarding station.

  On the other hand, according to the second rule, for example, when a train is boarded from each station at n stations (n is an integer of 2 or more) in order of increasing distance from the current position detected by the position detection unit 12, The station that takes a short time to the destination (the nearest station) is determined as the boarding station. This required time includes, for example, the time required to move from the current position to the boarding station and the required time from the boarding station to the destination. In this case, the time required to move from the current position to the boarding station is calculated, for example, by dividing the distance from the current position to the boarding station by a predetermined speed (initial value). The distance from the current position to the boarding station is included in the map information acquired by the boarding station route calculation unit 13, for example. In addition, the required time from the boarding station to the destination can be acquired by inquiring, for example, an information center.

  Here, the boarding station is determined according to the required time. However, for example, a station with a low fare may be determined as the boarding station. The required time or fare can be obtained from, for example, an information center provided outside. In addition, the boarding station may be determined based on the priority item specified by the user, not limited to the required time or fare.

  The boarding station route calculation unit 13 determines a boarding station based on, for example, one of the first rule and the second rule selected by the user. For example, when the above priority item is designated, the first rule or the second rule is selected by the user. Moreover, the structure by which the 1st rule or the 2nd rule is preset as a rule which determines a boarding station may be sufficient. Note that the number of boarding stations to be determined is not necessarily one, and a plurality of stations may be determined as boarding stations.

  The boarding station route calculation unit 13 determines a route (hereinafter referred to as a boarding station route) having the shortest distance from the current position detected by the position detection unit 12 to the boarding station based on the acquired map information. To calculate. If there are a plurality of ticket gates (entrances) at the boarding station, the route to the ticket gate closest to the platform (boarding position) of the route used by the user is calculated as the boarding station route.

  The movement speed calculation unit 14 calculates the speed at which the user holding the mobile terminal 10 moves based on the current position periodically detected by the position detection unit 12. The moving speed calculation unit 14 is an average speed information indicating an average (average speed) of speeds at which the user moves in each section (path section) in which the route calculated by the boarding station route calculation unit 13 is divided. Is stored (accumulated) in the movement history storage unit 15.

  The movement history storage unit 15 includes a section number (section identification information) for identifying a section of a route (boarding station route) that the user has traveled in the past, and an average (at the time) the user has moved in the past in the section. Average speed information indicating the speed is stored in association with each other. The average speed information stored in the movement history storage unit 15 is stored every time a speed (average speed) is calculated by the movement speed calculation unit 14. Hereinafter, the section number for identifying the section is simply referred to as the section number of the section.

  In the section storage unit 16, section length information indicating the section number stored in the movement history storage unit 15 and the distance (section length) of the section identified by the section number is stored in advance.

  The arrival time calculation unit 17 includes the boarding station route calculated by the boarding station route calculation unit 13, the speed calculated by the moving speed calculation unit 14 (the moving speed of the user at the current position), and the section number of the section of the boarding station route. Is determined by the boarding station route calculation unit 13 on the basis of the average speed information stored in the movement history storage unit 15 and the section length information stored in the section storage unit 16 in association with the section number. The time of arrival at the boarding station (hereinafter referred to as arrival time) is calculated. Details of the process of calculating the arrival time will be described later.

  The transit route acquisition unit 18 inquires, for example, an information center about the transit route of the train from the boarding station determined by the boarding station route calculation unit 13 to the destination input by the input unit 11. Thereby, the connecting route acquisition unit 18 acquires a connecting route from the information center via the network. At this time, the connection route acquisition unit 18 acquires a train connection route suitable for the priority item indicated by the priority item information input by the input unit 11. In addition, for example, the mobile terminal 10 can calculate the connection route without inquiring of the information center by holding various information such as a train timetable necessary for calculating the connection route, for example, by the mobile terminal 10. There is a general method for obtaining a transit route by inquiring of an information center as described above.

  The guidance display unit 19 includes the current position detected by the position detection unit 12, the map information acquired by the boarding station route calculation unit 13, the boarding station route and arrival time calculation unit 17 calculated by the boarding station route calculation unit 13. The arrival time calculated by the above is displayed (output) to the user.

  FIG. 2 shows an example of the data structure of the movement history storage unit 15 shown in FIG. As illustrated in FIG. 2, the movement history storage unit 15 stores a user ID, a section number, an average speed (information), and a date and time in association with each other.

  The user ID is identification information for identifying a user who uses the mobile terminal 10, for example. The section number is identification information for identifying the section in which the user identified by the user ID has moved. The average speed indicates an average speed at which the user identified by the user ID has moved through the section identified by the section number. The date / time indicates the date / time when the user identified by the user ID moves in the section identified by the section number.

  In the example illustrated in FIG. 2, the movement history storage unit 15 stores the user ID “1”, the section number “1”, the average speed “V1”, and the date and time “2008/2/21 14:25” in association with each other. ing. In this case, it is indicated that the user identified by the user ID “1” moved the section identified by the section number “1” at the average speed “V1” at 14:25 on February 21, 2008. .

  Similarly, the user ID “1”, the section number “2”, the average speed “V2”, and the date and time “2008/2/21 14:28” are stored in the movement history storage unit 15 in association with each other. In the movement history storage unit 15, user ID “1”, section number “3”, average speed “V3”, and date and time “2008/2/21 14:34” are stored in association with each other.

  In the example illustrated in FIG. 2, only the past movement history of the user identified by the user ID “1” is shown. However, for example, a user other than the user identified by the user ID “1” may identify the mobile terminal 10. When used, the section number, average speed, and date / time are stored in association with a user ID (for example, user ID “2”) for identifying the user.

  FIG. 3 shows an example of the data structure of the section storage unit 16 shown in FIG. As shown in FIG. 3, the section storage unit 16 stores section numbers, start points, end points, and section lengths in association with each other.

  The section number is the same as the section number stored in the movement history storage unit 15 described above. The start point indicates the point where the section identified by the section number starts, and the end point indicates the point where the section ends. The section length indicates the section length (section distance) identified by the section number.

  In the example illustrated in FIG. 3, the section storage unit 16 stores a section number “1”, a start point “A point”, an end point “B point”, and a section length “L1” in association with each other. In this case, the section identified by the section number “1” is “Point A” to “Point B”, and the section length is “L1”.

  Similarly, section number “2”, start point “B point”, end point “C point”, and section length “L2” are stored in the section storage unit 16 in association with each other. The section storage unit 16 stores a section number “3”, a start point “C point”, an end point “D point”, and a section length “L3” in association with each other.

  Next, the processing procedure of the mobile terminal 10 shown in FIG. 1 will be described with reference to the flowchart of FIG.

  First, the input unit 11 inputs destination information indicating a destination designated by the user by operating the mobile terminal 10, for example (step S1).

  Further, the input unit 11 inputs priority item information indicating a priority item designated by the user (step S2). This priority item includes the required time to the destination, the fare, the number of transfers, the number of steps for transfer, the distance traveled at the time of transfer, and the like.

  At this time, the user can select either the first rule or the second rule as a rule for determining the boarding station described above. In the following description, it is assumed that the first rule is selected.

  Next, the position detection unit 12 detects the current position of the user holding the mobile terminal 10 using radio waves from, for example, GPS hygiene (step S3).

  The boarding station route calculation unit 13 acquires map information indicating a map around the current position detected by the position detection unit 12 from the outside. The boarding station route calculation part 13 acquires map information via a network, for example.

  The boarding station route calculation unit 13 determines a boarding station to be used for the user holding the mobile terminal 10 to arrive at the destination based on the current position detected by the position detection unit 12 and the acquired map information. (Step S4). Here, the boarding station route calculation unit 13 determines, as the boarding station, a station that is close to the current position detected by the position detection unit 12, for example, based on the first rule described above. At this time, the boarding station route calculation unit 13 may determine a plurality of stations as boarding stations.

  The boarding station route calculation unit 13 calculates a route (boarding station route) having the shortest distance from the current position detected by the position detection unit 12 to the station based on the acquired map information (step). S5).

  Next, the moving speed calculation unit 14 calculates a moving speed (moving speed) of the user based on the current position of the user periodically detected by the position detection unit 13 (step S6). The calculated speed is stored in the movement history storage unit 15 as a movement history.

  Here, with reference to FIG. 5, the process in which the movement speed calculation part 14 calculates a user's movement speed is demonstrated concretely.

  In the example shown in FIG. 5, it is assumed that the user is at the current position 100, for example. Further, it is assumed that there are an X station 101 of A electric railway and a Y station 102 of B electric railway near the current position 100 of the user.

  Here, it is assumed that the user is moving from the current position 100 toward the X station 101, for example. In this case, for example, it is assumed that the current position of the user detected by the position detection unit 12 at time t1 is the coordinates (a1, g1). Further, it is assumed that the current position of the user detected by the position detection unit 12 at the time t2 after a predetermined time has elapsed from the time t1 is the coordinates (a2, g2). Hereinafter, the coordinates (a1, g1) at time t1 are expressed as t1 (a1, g1). Similarly, coordinates (a2, g2) at time t2 are expressed as t2 (a2, g2).

  In this case, the moving speed calculation unit 14 calculates the moving distance of the user from t1 (a1, g1) and t2 (a2, g2). Here, it is assumed that the calculated moving distance of the user is L.

  Thereby, the moving speed calculation unit 14 calculates a speed (average speed) V between the moving distances L of the user. Specifically, the speed V is calculated by L / (t2-t1).

  Returning to the flowchart of FIG. 4 again, the arrival time calculation unit 17 determines the boarding station route calculated by the boarding station route calculation unit 13, the speed calculated by the moving speed calculation unit 14, the user ID for identifying the user, and the boarding. Based on the average speed information stored in the movement history storage unit 15 in association with the section number of the section of the station route and the section length information stored in the section storage unit 16 in association with the section number The time (arrival time) at which the user arrives at the boarding station determined by the route calculation unit 13 is calculated (step S6).

  Next, the connection route acquisition unit 18 determines the train connection route from the boarding station determined by the boarding station route calculation unit 13 to the destination (or the nearest station of the destination) input by the input unit 11. Contact the information center. At this time, the transit route acquisition unit 18 uses the arrival time calculated by the arrival time calculation unit 17, the boarding station, the getting-off station (the destination or the nearest station of the destination) and the priority item information input by the input unit 11, for example. Send to the information center. Thereby, the transfer route acquisition unit 18 acquires a transfer route that is a transfer route from the boarding station to the alighting station and that is suitable for the priority item indicated by the priority item information (step S8).

  The guidance display unit 19 calculates the current position of the user detected by the position detection unit 12, the map information acquired by the boarding station route calculation unit 13, the boarding station route calculated by the boarding station route calculation unit 13, and the arrival time calculation. The arrival time calculated by the unit 17 and the connecting route acquired by the connecting route acquiring unit 18 are displayed for guidance to the user (step S9). Note that the present invention is not limited to the guidance display, and for example, a configuration in which guidance is provided by voice may be used.

  Here, it is determined whether or not the user has arrived at the boarding station (step S10). When the user arrives at the boarding station (YES in step S10), the process ends.

  On the other hand, when it is determined that the user has not arrived at the boarding station (NO in step S10), the process returns to step S3 and is repeated. Thereby, for example, the current position and arrival time displayed for guidance are updated as appropriate. For example, when the user is moving along the boarding station route, if the user's moving speed decreases due to, for example, weather or congestion, the arrival time is updated accordingly, and the updated arrival time is changed accordingly. The connecting route is displayed as guidance.

  For example, when a plurality of boarding stations are determined by the boarding station route calculation unit 13, for example, a configuration in which a plurality of boarding station routes are displayed for guidance may be used.

  FIG. 6 shows an example of a guidance display screen when guidance is displayed by the guidance display unit 19. In the example shown in FIG. 6, map information (hereinafter simply referred to as a map) 31 indicating a map around the current position of the user is displayed on the guidance display screen 30. In the example of the guidance display screen 30, for example, it is assumed that the current position of the user at the current time “9:50” is the current position 100 on the map 31. The destination specified by the user is assumed to be Z station.

  Here, for example, a case is assumed in which the boarding station route calculation unit 13 determines the X station 101 of A Electric Railway and the Y station 102 of B Electric Railway as the boarding stations. In this case, the guidance display screen 30 displays a boarding station route 101 a from the current position 100 of the user to the X station 101 and a boarding station route 102 a from the current position 100 to the Y station 102.

  For example, a case is assumed where it is better to use X station from the priority item specified by the user or the arrival time of the destination. In this case, the X station is the first candidate station, and the Y station is the second candidate station. Thereby, as shown in the guidance display screen 30, the boarding station route 101a from the current position 100 to the X station 101 which is the first candidate station is displayed, for example, by a solid line. On the other hand, the boarding station route 102a from the current position 100 to the second candidate station Y station 102 is displayed by, for example, a broken line. In addition, although demonstrated as what distinguishes the boarding station route to the 1st candidate station and boarding station route to the 2nd candidate station here with the continuous line and the broken line, if these can be distinguished, it will be another display method. There may be.

  As shown in FIG. 6, “X station estimated arrival time 10:02” is displayed on the guidance display screen 30 as the arrival time of the X station 101 which is the first candidate station. In addition, the guidance display screen 30 displays a transfer route (first candidate transfer route) from the X station 101 that is the first candidate station to the Z station that is the destination. Similarly, the guidance display screen 30 displays a transfer route (second candidate transfer route) from the Y station 102 as the second candidate station to the Z station as the destination.

In the example shown in FIG. 6, the guidance display screen 30 has a first candidate transit route as
1: Depart from A Electric Railway X Station 10:05 Express P bound for Q Station 10:22 Transfer
Q Departure from station 10:25 Ordinary R bound Z station 10:35
Is displayed. In addition, on the guidance display screen 30, as the second candidate transfer route,
2: Depart from B Electric Railway Y Station 10:10 Ordinary S bound Z Station 10:45
Is displayed. In addition, P, Q, R, and S displayed on this connection route each represent a station.

  Here, for example, it is assumed that the user's current position, arrival time, and the like are updated at “9:55” 5 minutes after the above-described guidance display screen 30 is displayed. In this case, it is assumed that the arrival time of the X station 101 calculated by the arrival time calculation unit 17 is updated to “10:06”.

  In this case, it is not possible to get on the “10:05” train on the first candidate transfer route displayed on the guidance display screen 30 shown in FIG. For this reason, as shown in the guidance display screen 30, for example, when the distance from the current position to the X station and the Y station is the same, and the estimated arrival times of the X station 101 and the Y station 102 are both “10:06”. For example, the second candidate transfer route (transfer route when using Y station 102) displayed on the above-described guidance display screen 30 based on the arrival time of the Z station that is the user's destination is the optimum route. It becomes. As a result, the first candidate station becomes Y station and the second candidate station becomes X station.

  As a result, for example, the second candidate transit route displayed on the guidance display screen 30 is displayed as the first candidate transit route.

  Here, FIG. 7 shows an example of the guidance display screen 40 when the guidance display on the guidance display screen 30 shown in FIG. 6 is updated as described above.

  In the example shown in FIG. 7, a map 31 indicating a map around the current user position is displayed on the guidance display screen 40, as with the guidance display screen 30 described above. In the map 31, for example, the current user position at the current time “9:55” is the current position 100a.

  The guidance display screen 40 displays “Y station arrival prediction time 10:06” as the arrival time of the first candidate station Y station 102.

  In addition, since the first candidate station has been changed from the X station 101 to the Y station 102 as described above, the boarding station route 102a from the current position 100a to the Y station 102 is displayed with a solid line on the guidance display screen 40, The boarding station route 101a from the current position 100a to the X station 101 is displayed by a broken line.

  On the guide table screen 40, the transfer route from the first candidate station Y station 102 to the destination Z station is displayed as the first candidate transfer route. Further, the transfer route from the X station 101 as the second candidate station to the Z station as the destination is displayed as the transfer route of the second candidate.

In the example shown in FIG. 7, the guidance display screen 40 has a first candidate transit route as
1: Departure from B Electric Railway Y Station 10:10 Ordinary S bound Z Station 10:45
Is displayed. In addition, the guidance display screen 40 has a second candidate transfer route,
2: Depart from A Electric Railway X Station 10:15 To Express T Arrival at U Station 10:32 Transfer
From U Station 10:36 Ordinary V bound Z Station 10:46
Is displayed. In addition, T, U, and V displayed on this connection route each represent a station.

  As described above, for example, when the arrival time at the X station 101 is updated from “10:02” to “10:06” based on the current position of the user, the moving speed of the user, and the like, FIG. The guide display screen 30 shown is updated to the guide display screen 40 shown in FIG.

  Next, the details of the processing procedure of the arrival time calculation unit 17 described above will be described with reference to the flowchart of FIG.

  First, the arrival time calculation unit 17 detects the current detected by the position detection unit 12 in a section in which the boarding station route calculated by the boarding station route calculation unit 13 is divided (hereinafter referred to as a boarding station route section). The average speed information stored in the movement history storage unit 15 is acquired in association with the section number (section identification information) of the section including the position and the user ID identifying the user holding the mobile terminal 10. This average speed information indicates the average speed at which the user identified by the user ID has moved in the past in the section identified by the section number stored in the movement history storage unit 15 in association with the average speed information. In addition, when the user has moved the section including the current position a plurality of times in the past, a plurality of pieces of average speed information is acquired. In this case, the arrival time calculation unit 17 acquires an average value of average speeds indicated by the acquired plurality of average speed information. Hereinafter, the acquired average value is used as an average speed (information).

  The arrival time calculating unit 17 calculates the ratio of the speed (the moving speed of the user at the current position) calculated by the moving speed calculating unit 14 to the average speed indicated by the acquired average speed information (step S21). That is, the arrival time calculation unit 17 calculates the ratio by dividing the speed calculated by the movement speed calculation unit 14 by the average speed indicated by the acquired average speed information.

  Next, the arrival time calculation unit 17 calculates the average speed indicated by the average speed information stored in the movement history storage unit 15 in association with the section number of the section for each section of the boarding station route. Multiply by a percentage. Thereby, the arrival time calculation part 17 calculates the estimated moving speed for every section of the boarding station route calculated by the boarding station route calculation part (step S22). This predicted moving speed is a predicted value of the moving speed of the user for each section. In addition, since the actual speed is calculated by the moving speed calculation unit 14 in the section including the current position detected by the position detecting unit 12, it is not necessary to calculate the predicted moving speed.

  The arrival time calculation unit 17 acquires, for each section of the boarding station route, section length information (hereinafter referred to as section length information of the section) stored in the section storage unit 16 in association with the section number of the section. . The arrival time calculation unit 17 divides, for each section of the boarding station route, the section length indicated by the acquired section length information of the section by the calculated predicted movement speed of the section. Thereby, the arrival time calculation part 17 calculates the time required when a user moves the said area for every area of a boarding station route (step S23). Note that, in a section including the current position detected by the position detection unit 12, the section length indicated by the section length information of the section is divided by the speed calculated by the moving speed calculation unit 14, thereby making the section a user. The time required to move is calculated.

  The arrival time calculation unit 17 adds the time required for movement for each section of the calculated boarding station route (step S24). As a result, the arrival time calculation unit 17 calculates the time required for the user to move from the current position of the user to the boarding station (hereinafter referred to as the time required for the boarding station).

  The arrival time calculation unit 17 calculates, for example, the time after the elapse of time required for the boarding station calculated from the current time as the arrival time (step S25).

  Here, with reference to FIG. 9, the processing procedure of the arrival time calculation part 17 is demonstrated concretely. Here, a case will be described in which the time at which the user at the current position 100 shown in FIG. 9 arrives at the X station 101 as the boarding station is calculated.

  In the example shown in FIG. 9, the section of the boarding station route from the current position 100 to X station 101 is a section identified by section number n (hereinafter referred to as section n), a section identified by section number n + 1. (Hereinafter referred to as section n + 1), a section identified by section number n + 2 (hereinafter referred to as section n + 2), a section identified by section number n + 3 (hereinafter referred to as section n + 3), and a section number n + 4 It is assumed that it is a section (hereinafter referred to as section n + 4).

  Here, FIG. 10 is a diagram showing a correspondence relationship for each section (section n, section n + 1, section n + 2, section n + 3 and section n + 4) of the above-described boarding station route.

  As shown in FIG. 10, it is assumed that the section length of the section n is Ln. Further, it is assumed that the average speed in the section n is Vn. Hereinafter, similarly, the section length of the section n + 1 is assumed to be Ln + 1, and the average speed of the section n + 1 is assumed to be Vn + 1. The section length of the section n + 2 is Ln + 2, and the average speed of the section n + 2 is Vn + 2. Assume that the section length of the section n + 3 is Ln + 3, and the average speed of the section n + 3 is Vn + 3. Assume that the section length of the section n + 4 is Ln + 4, and the average speed of the section n + 4 is Vn + 4.

  First, the arrival time calculation unit 17 acquires an average speed of a section including the current position 100 among sections (section n, section n + 1, section n + 2, section n + 3, and section n + 4) of the boarding station route. In the example illustrated in FIG. 9, the current position 100 of the user is included in the section n. Therefore, the arrival time calculation unit 17 acquires the average speed Vn of the section n.

  Here, as shown in FIG. 10, the moving speed of the user at the current position 100 calculated by the moving speed calculation unit 14 is assumed to be Wn (hereinafter referred to as a measured moving speed Wn of the section n). In addition, since the section n + 1, the section n + 2, the section n + 3, and the section n + 4 are sections where the user moves from now on, there is no measured moving speed.

  Next, the arrival time calculation unit 17 calculates the ratio of the measured moving speed Wn in the section n to the average speed Vn in the section n. Here, the ratio Wn / Vn is calculated by the arrival time calculation unit 17.

  The arrival time calculation unit 17 multiplies the average speed of the section by the calculated ratio Wn / Vn for each section of the boarding station route other than the section n including the current position 100. Thereby, the arrival time calculation unit 17 calculates the predicted moving speed for each section of the boarding station route.

  Specifically, as shown in FIG. 10, by multiplying the average speed Vn + 1 of the section n + 1 by Wn / Vn, the predicted movement speed Vn + 1 * Wn / Vn of the section n + 1 is calculated. Similarly, the predicted travel speed Vn + 2 * Wn / Vn for the section n + 2, the predicted travel speed Vn + 3 * Wn / Vn for the section n + 3, and the predicted travel speed Vn + 4 * Wn / Vn for the section n + 4 are calculated.

  The arrival time calculation unit 17 divides the section length of the section by the predicted movement speed of the section for each section of the boarding station route. Thereby, the arrival time calculation unit 17 calculates the time required for the user to move in the section of the boarding station route (hereinafter referred to as a predicted required time of the section).

  Here, as shown in FIG. 10, by dividing the section length Ln + 1 of the section n + 1 by the predicted movement speed Vn + 1 * Wn / Vn of the section n + 1, the predicted required time Ln + 1 * Vn / (Vn + 1 * Wn) of the section n + 1 is obtained. Calculated. Similarly, the estimated required time Ln + 2 * Vn / (Vn + 2 * Wn) for the interval n + 2, the estimated required time Ln + 3 * Vn / (Vn + 3 * Wn) for the interval n + 3, and the estimated required time Ln + 4 * Vn / (Vn + 4 * Wn) for the interval n + 4 Is calculated.

  For the section n including the current position 100, the estimated required time Ln / Wn of the section n is calculated by dividing the section length Ln of the section n by the movement measurement speed Wn.

  The arrival time calculation unit 17 calculates the estimated required time for each section, that is, the predicted required time Ln / Wn for the section n, the predicted required time Ln + 1 * Vn / (Vn + 1 * Wn) for the section n + 1, and the predicted required for the section n + 2. The total of time Ln + 2 * Vn / (Vn + 2 * Wn), predicted required time Ln + 3 * Vn / (Vn + 3 * Wn) of section n + 3 and predicted required time Ln + 4 * Vn / (Vn + 4 * Wn) of section n + 4 from the current position 100 It is calculated as the estimated required time to the X station 101 which is the boarding station.

  Thereby, the arrival time calculation unit 17 calculates, for example, the time after the predicted required time has elapsed from the current time to the X station 101 from the current time as the arrival time (estimated arrival time).

  As described above, by modifying the accumulated user's past movement history (Vn, Vn + 1, Vn + 2, Vn + 3 and Vn + 4) with the measured movement speed Wn, the predicted travel time is predicted, for example, weather, physical condition, accompanying person Even when conditions such as the above change, it is possible to calculate a more accurate arrival time according to the current situation of the user.

  Here, a case has been described in which the time at which the user at the current position 100 arrives at the X station 101 has been described. For example, the same applies even when the time at which the user at the current position 100 arrives at the Y station 102 is calculated. Is calculated as follows.

  In addition to the method described above, for example, the total of the section lengths (Ln, Ln + 1, Ln + 2, Ln + 3, and Ln + 4) of the section of the boarding station route, that is, the prediction required by dividing the distance of the boarding station route by the measured moving speed Wn. Time may be calculated, and the arrival time may be calculated from the estimated required time.

  In the present embodiment, the movement speed calculation unit 14 has been described as calculating the movement speed of the user based on the current position (change) of the user holding the mobile terminal 10 that is periodically calculated. The method for calculating the moving speed of the user is not limited to this. For example, when the user is moving using a bicycle or a wheelchair, the moving speed of the user may be calculated using an instruction value of a speedometer provided on the bicycle or wheelchair.

  Moreover, the moving speed calculation part 14 may be the structure which calculates an average moving speed from the information of movement between base stations of portable communication terminals, such as a mobile telephone or PHS (Personal Handy-phone System), for example.

  Here, with reference to FIG. 11, for example, the process of calculating the average moving speed from the information on the movement of the mobile communication terminal between base stations will be described.

  Here, for example, a case where the average moving speed when the user at the current position 100 moves toward the X station 101 as the boarding station will be described. As shown in FIG. 11, it is assumed that base stations 201 to 203 are installed around the current position 100, for example.

  Also, as shown in FIG. 11, the distance between the base station 201 and the base station 202 is assumed to be l1. Further, the distance between the base station 202 and the base station 203 is assumed to be l2.

  Here, it is assumed that the time when the user moves between the base station 201 and the base station 202 is t1, and the time when the user moves between the base station 202 and the base station 203 is t2. In this case, for example, only the data of movement between adjacent base stations does not provide an accuracy sufficient to obtain the speed. Therefore, by using l1, l2, t1, and t2, the average moving speed V is, for example, (l1 + l2) / Calculated by (2 * (t2-t1)).

  Next, processing after the user holding the mobile terminal 10 arrives at the boarding station while confirming the boarding station route displayed on the guidance display screen, for example, will be described.

  As described above, when the user arrives at the boarding station according to the boarding station route displayed on the guidance display screen, the user uses the train while confirming the connection route displayed on the guidance display screen. It will move to the ground (or the nearest station of the destination).

  As described above, when the user is moving along the boarding station route, the moving speed and arrival time of the user are periodically calculated, and the connection route according to the arrival time is updated. However, for example, when the user is on the train from the boarding station, the arrival time of the train has already been acquired as a connection route, so the moving speed and arrival time of the user are calculated, and the connection route is updated. There is no need. Therefore, for example, from the viewpoint of reducing power consumption of the mobile terminal 10, after the user arrives at the boarding station (that is, while the user is using the train), the mobile speed that the mobile terminal 10 has is calculated. It is preferable to stop the functions of the calculation unit 14, the arrival time calculation unit 17, and the transit route acquisition unit 18 (hereinafter referred to as the function of the mobile terminal 10 starting from the calculation of the moving speed).

  Hereinafter, the first to third methods will be described as methods for stopping the function of the mobile terminal 10 starting from the calculation of the moving speed after the user arrives at the boarding station.

  First, the first method assumes a case where the mobile terminal 10 has a function of a boarding card used when the train uses (gets on or gets off), and uses the function of the boarding card. Is the method. According to the first method, when the mobile terminal 10 enters the boarding station using the boarding card function of the mobile terminal 10 from the ticket gate provided at the boarding station, the user arrives at the boarding station. The function of the portable terminal 10 starting from the calculation of the moving speed is stopped as the person getting on the train. On the other hand, when the user arrives at the nearest station (disembarking station) of the destination and exits from the disembarking station using the function of the boarding card of the mobile terminal 10 from the ticket gate at the disembarking station, the mobile phone starts from the calculation of the moving speed. The stop of the function of the terminal 10 is released (resumed).

  Next, the second method is a method of using a radio station installed for guidance, advertisement, broadcasting or the like in a train, for example. According to the second method, when the mobile terminal 10 receives radio waves (for example, infrared light, ultrasonic waves, etc.) of a radio station installed in the train, for example, the user is assumed to have boarded the train. The function of the portable terminal 10 starting from the movement speed calculation is stopped. On the other hand, when radio waves installed in the train are no longer received, it is assumed that the user got off the train, and the suspension of the function of the mobile terminal 10 starting from the calculation of the moving speed is cancelled.

  Further, the third method is a method of using mobile terminals held by many users assuming that there are many users holding mobile terminals such as mobile phones in the train. According to the third method, the mobile terminal 10 recognizes a mobile terminal that exists in the vicinity of the mobile terminal 10, and the majority of the recognized mobile terminals (for example, 80% or more) remain unchanged. If there is, it is assumed that the user holding the mobile terminal 10 gets on the train, and the function of the mobile terminal 10 starting from the movement speed calculation is stopped. On the other hand, when the recognized mobile terminal changes greatly, it is assumed that the user holding the mobile terminal 10 got off, and the suspension of the function of the mobile terminal 10 starting from the calculation of the moving speed is released.

  Note that the method of stopping the function of the mobile terminal 10 starting from the calculation of the moving speed is not limited to the first to third methods described above, and other methods may be used.

  As described above, in this embodiment, the moving speed at the current position of the user is calculated, and the arrival time at which the user arrives at the boarding station is calculated according to the moving speed, thereby improving the accuracy of the arrival time. Can do. Thereby, in this embodiment, it becomes possible to perform the optimal route guidance to the destination by accurately predicting the time of arrival at the station (boarding station) to be used by the user.

  Moreover, in this embodiment, since a user's present position and a user's moving speed are calculated regularly, the arrival time which arrives at a boarding station can be updated in real time. Thereby, for example, when it is necessary to update the transit route of the train displayed on the guidance display screen, the optimum transit route is acquired according to the updated arrival time, and the transit route is displayed as guidance. . Therefore, in the present embodiment, it is possible to provide the user with accurate guidance on the boarding station route to the train and the train connection route.

  Moreover, in this embodiment, after a user arrives at a boarding station, it becomes possible to stop the function of the portable terminal 10 which starts from a movement speed calculation by the above-mentioned 1st-3rd method, for example. Thereby, for example, while the user is on the train, the power consumption of the mobile terminal 10 and the like can be reduced by stopping unnecessary functions (functions of the mobile terminal 10 starting from the calculation of the moving speed).

  In this embodiment, as described above, the arrival time of the boarding station is calculated based on the average speed at which the user has moved in the past in the section of the boarding station route. When moving (passing) for the first time, the past movement history (average speed) is not stored. In this case, for example, a configuration using past movement history of a user other than this user may be used.

  Moreover, in this embodiment, although demonstrated that the portable terminal 10 was provided with the movement history storage part 15 and the area storage part 16, the said movement history storage part 15 and the area storage part 16 were provided in the above-mentioned information center, You may be the structure which calls and uses these at any time.

  In the present embodiment, the mobile terminal 10 includes a boarding station route calculation unit 13, a movement speed calculation unit 14, a movement history storage unit 15, a section storage unit 16, an arrival time calculation unit 17, and a connection route acquisition unit 18. However, the configuration may be such that each of the units 13 to 18 is provided in a server such as a web, and the mobile terminal 10 and a guidance display system including the server are provided. In this guidance display system, the current position (information indicating) detected by the position detection unit 12 of the mobile terminal 10 is transmitted to the server, and the server calculates the boarding station route calculation unit 13 and the movement based on the current position. Processing of the speed calculation unit 14, the arrival time calculation unit 17, and the transit route acquisition unit 18 is executed. Information (guidance information) such as the boarding station route and arrival time obtained in this way is transmitted from the server to the portable terminal 10, and the guidance information is output (displayed) by the guidance display unit 19 of the portable terminal 10.

  Further, in the present embodiment, for example, a case where a train is used to move to a destination, that is, a case where a station is used has been described, but the present invention can be applied even when other transportation such as an airport is used. It is.

  Further, in the present embodiment, it has been described that the boarding station route from the current position of the user to the boarding station is displayed. However, for example, when the destination is not a station, that is, when it is a point such as an address, for example. When arriving at the nearest station of the destination, it is also possible to display the route from the nearest station to the destination in the same way as the boarding station route.

[Modification]
Next, a modification of the present embodiment will be described with reference to FIG.

  FIG. 12 is a block diagram mainly showing a functional configuration of the mobile terminal according to the present modification. The same parts as those in FIG. 1 described above are denoted by the same reference numerals, and detailed description thereof is omitted. Here, parts different from FIG. 1 will be mainly described.

  As shown in FIG. 12, the mobile terminal 300 includes a remote input unit 301. In this embodiment, the remote input part 301 shall be implement | achieved when the computer of the said portable terminal 300 runs the program stored in the memory which comprises the portable terminal 300, for example. This program can be stored in advance in a computer-readable storage medium and distributed. Moreover, this program may be downloaded to the portable terminal 300 via a network.

  The remote input unit 301 inputs (receives) destination information designated by a user other than the user who holds (uses) the mobile terminal 300 from the outside of the mobile terminal 300, for example. That is, in this modification, for example, destination information is remotely input from the outside. In this case, the remote input unit 301 inputs destination information by using a communication function that the mobile terminal 300 has. Similarly, the remote input unit 301 inputs priority item information indicating a priority item from the outside. As described above, the priority items include required time, fare, number of transfers, and the like.

  As described above, according to this modification, a user other than the user who holds (uses) the mobile terminal 300, for example, a staff member of the service center or the family of the user who holds the mobile terminal 300, for example, specifies the destination. Thus, the destination information indicating the destination can be remotely input. Therefore, according to this modification, the user holding the mobile terminal 300 can input (receive) the destination information from the outside without inputting the destination. Thereby, the user can arrive at the destination by the optimal route only by following the guidance displayed on the mobile terminal 300.

  In this modification, the remote input unit 301 is described as being replaced with the input unit 11 in the above-described embodiment, but the remote input unit 301 is further provided in addition to the input unit 11. It doesn't matter.

  Note that the present invention is not limited to the above-described embodiment or its modification, but can be embodied by modifying the components without departing from the scope of the invention in the implementation stage.
