The real time clock has a function of calculating the current date and time.

  The departure time notification system 1 performs notification processing for notifying the user of the departure time based on the above hardware configuration. The storage device 130 of the mobile terminal 10 and the storage device 220 of the server device 20 each store a program for performing this notification processing (referred to as a notification processing program). In the departure time notification system 1, the control device 110 of the mobile terminal 10 executes the notification processing program to control each device shown in FIG. 3, and the control device 300 of the server device 20 executes the notification processing program. By controlling each device shown in FIG. 4, the following functions are realized.

  FIG. 5 is a diagram showing functions realized in the departure time notification system 1. First, functions realized in the mobile terminal 10 will be described. The mobile terminal 10 includes a measurement data generation unit 101, a movement stillness determination unit 102, a communication unit 103, a notification unit 104, an attribute data generation unit 105b, and a scheduled data extraction unit 106c. Among these, the attribute data generation unit 105b and the scheduled data extraction unit 106c are functions that are not used in the present embodiment, and will be described in later embodiments.

  The measurement data generation unit 101 includes GPS position information measured by the positioning device 160 shown in FIG. 3, that is, a terminal position and a positioning error, a time when the terminal position is measured (hereinafter referred to as “measurement time”), and a mobile terminal. Measurement data indicating a user ID (referred to as “001” in the present embodiment) defined for 10 is generated. The measurement data generation unit 101 generates this measurement data a predetermined number of times at intervals of several seconds to several tens of seconds (the measurement data generated in this way is referred to as one set of measurement data), and the generation is started from several minutes. Repeat at intervals of several tens of minutes. In this embodiment, the measurement data generated twice with an interval of 5 seconds is set as one set, and the measurement data generation unit 101 repeatedly generates one set of measurement data every 5 minutes. The measurement data generation unit 101 supplies the generated measurement data to the moving stillness determination unit 102. The measurement data generation unit 101 is a function realized by the control device 110 and the positioning device 160 in cooperation.

  The moving stillness determination unit 102 is a unit that determines whether the mobile terminal 10 is moving or stationary based on the measurement data generated by the measurement data generation unit 101. When the distance between the two terminal positions indicated by one set of measurement data is equal to or greater than the threshold, the moving stillness determination unit 102 determines that the mobile terminal 10 is moving, and the distance is less than the threshold. It is determined that the mobile terminal 10 is not moving, that is, is stationary. When the moving stationary determination unit 102 determines that the mobile terminal 10 is moving (that is, determines that the mobile terminal 10 is moving), the moving stationary determination unit 102 supplies the communication unit 103 with the newer one of the two measurement data used for the determination. However, if it is determined that the mobile terminal 10 is stationary (that is, it is determined that the mobile terminal 10 is stationary), no measurement data is supplied to the communication unit 103. The moving stillness determination unit 102 is a function realized by the control device 110 and the storage device 130 in cooperation.

  When the measurement data is supplied from the moving stillness determination unit 102, the communication unit 103 transmits the supplied measurement data to the server device 20. That is, the communication unit 103 transmits measurement data when the movement / stillness determination unit 102 determines movement, and does not transmit measurement data when it is determined to be stationary. Thereby, compared with the case where measurement data is transmitted regardless of whether the mobile terminal 10 is moving, the load on the communication path used when the measurement data is transmitted from the mobile terminal 10 to the server device 20 Less. In addition, the communication unit 103 receives data transmitted from the server device 20. The data received by the communication unit 103 is, for example, the notification data described above. When receiving the notification data, the communication unit 103 supplies the notification data to the notification unit 104. The communication unit 103 is a function realized by the control device 110 and the communication device 170 in cooperation.

  The notification unit 104 is a means for notifying the user of the departure time and the station indicated by the notification data supplied from the communication unit 103. For example, the notification unit 104 displays a character string representing the departure time or the station on the display surface of the display device 140 illustrated in FIG. When the user sees these character strings displayed on the display surface, the user is notified of the departure time and the station indicated by the notification data. In this case, the control device 110 and the display device 140 cooperate to function as the notification unit 104. The notification unit 104 may notify the user by causing the voice input / output device 150 to output a voice representing the departure time or station indicated by the notification data. In this case, the control device 110 and the voice input / output device 150 cooperate to function as the notification unit 104.

Specifically, the acquisition unit 320 acquires the terminal position and the measurement time indicated by the latest measurement data among the measurement data held in the server device 20. The latest measurement data here is measurement data transmitted from the mobile terminal 10 during the period in which the mobile terminal 10 is moving (the period in which the moving stationary determination unit 102 determines that the mobile terminal 10 is moving). If the mobile terminal 10 is stationary (the period during which the mobile stationary determination unit 102 determines that it is stationary), it is the latest measurement data transmitted from the mobile terminal 10 in the past. It is. The acquisition unit 320 performs the operation of acquiring the terminal position and the measurement time in this manner at an interval of a predetermined time (in this embodiment, 5 minutes). In the notification process, the departure time is notified to the user based on the terminal position and the measurement time acquired by the acquisition unit 320. The acquisition unit 320 is a function realized by the control device 300, the communication device 210, and the storage device 220 in cooperation. When the measurement data is supplied from the communication unit 310, the acquisition unit 320 stores the measurement data in the measurement data storage unit 221. The measurement data transmitted from the mobile terminal 10 in the past is the measurement data stored in the measurement data storage unit 221. Moreover, the acquisition part 320 will supply the measurement data which show the acquired terminal position and measurement time to the path | route extraction part 330, if said operation | movement of acquisition is performed.

The measurement data storage unit 221 stores the measurement data supplied from the acquisition unit 320. The measurement data storage unit 221 functions as an acquisition result storage unit that stores the terminal position and measurement time indicated by the stored measurement data, that is, the terminal position and measurement time acquired by the acquisition unit 320 in association with each other. .
The route extraction unit 330 includes a route estimation unit 331 and a spatially identical route determination unit 332. Measurement data is supplied from the acquisition unit 320 to the route estimation unit 331. The route estimation unit 331 estimates a route along which the mobile terminal 10 moves based on the terminal position indicated by the supplied measurement data. Hereinafter, a method by which the route estimation unit 331 estimates a route will be described with reference to FIGS. 6 and 7.

The table of FIG. 6 shows GPS position information measured at three times of measurement dates t ₁ , t ₂ and t ₃ , that is, the terminal position and positioning error (unit: m). The terminal position is indicated by latitude and longitude, respectively. Specifically, the latitude x ₁ is the measurement time t _1, longitude y _1, the positioning error 100 m, latitude x ₂ is the measurement time t _2, longitude y _2, the positioning error 140m is the measured time t ₃ latitude It is shown that x ₃ , longitude y ₃ , and positioning error 80 m are measured.

FIG. 7 is a diagram illustrating an example of a route estimated by the route estimation unit 331. In FIG. 7, east, west, south, and north are indicated by arrows. FIG. 7 shows position information (p _n , t _n ) represented by GPS position information _pn and measurement date and time t _n . n is 1, 2 and 3 in this example. Specifically, the position information (p _n , t _n ) is indicated by a square whose side is twice the positioning error with the terminal position as the center. Each side of this square is along the east-west direction and the north-south direction, respectively. For example, the position information (p ₁ , t ₁ ) is indicated by a 200 m square area whose length of one side centered on the terminal position (x ₁ , y ₁ ) is twice the positioning error (100 m). Yes.

FIG. 7 shows a minimum rectangle MBR (Minimum Bounding Rectangle) _{n- (n + 1)} that includes two pieces of position information (p _n , t _n ) with consecutive measurement times. n is 1 and 2 in this example. For example, MBR _1-2 is the smallest rectangle that contains location information (p ₁ , t ₁ ) and (p ₂ , t ₂ ). Each MBR is represented by, for example, the latitude and longitude of the northwest corner and the latitude and longitude of the southeast corner. In the case of MBR _1-2 , it is represented by the latitude and longitude of the northwest corner W1 and the southeast corner W2 shown in FIG. The latitude of W1 is a latitude 140 m north of x ₂ , and the longitude of W 1 is a longitude 100 m west of y ₁ . Further, the latitude of W2 is a latitude 100 m south of x ₁ , and the longitude of W2 is a longitude 140 m east of x ₂ . Likewise, the latitude and longitude of a corner W3 and W4 in the MBR _2-3 (W4 and W2 common corner) can also be represented respectively by using the GPS position information p ₂ and p _3.

Adjacent MBRs include one position information in both. For example, MBR _1-2 and MBR _2-3 include position information (p ₂ , t ₂ ) in both. Therefore, these MBRs are continuous without leaving. The route estimation unit 331 estimates a polygon formed by these MBRs as the route r ₁ . The route r ₁ is obtained by connecting the terminal positions acquired by the acquisition unit 320 from when the mobile terminal 10 starts moving to when it ends. The route r ₁ is represented by, for example, the latitude and longitude of the angles W1, W2, W3, and W4 of each MBR described above. The route estimation unit 331 estimates the route every time new measurement data is supplied after the supply of the measurement data from the acquisition unit 320 is started. The route estimation unit 331 supplies the route storage unit 222 with data indicating the estimated route, that is, data indicating the latitude and longitude of these corners. Hereinafter, the route estimated by the route estimation unit 331 is referred to as an “estimated route”. Data indicating a route such as an estimated route is referred to as “route data”. The route data is represented by the latitude and longitude of the corners of each MBR described above. The route estimation unit 331 supplies route data indicating the estimated route and data indicating position information used when estimating the estimated route (that is, measurement data) to the spatially same route determination unit 332.

The spatially identical route determination unit 332 determines whether or not the estimated route described above is the same as the route on which the mobile terminal 10 has moved in the past (hereinafter referred to as “past route”). The past route referred to here is a route indicated by route data stored in the route storage unit 222 before the measurement time acquired by the acquisition unit 320. When making this determination, the spatially identical route determination unit 332 stores the route data indicating the past route and the measurement data storage unit 221 stored in the past, that is, before the measurement time acquired by the acquisition unit 320. Use measurement data.
8 and 9 are diagrams for explaining a determination method performed by the spatially identical route determination unit 332. 8 and 9, the past route r ₁ and each position information shown in FIG. 7 are indicated by a two-dot chain line. Further, FIG. 8 shows an estimated route r ₁₁ represented by four pieces of position information (p _n , t _n ) from 11 to 14 as n, and in FIG. An estimated route r ₂₁ represented by three position information (p _n , t _n ) is shown.

When the route data and the measurement data are supplied from the route estimation unit 331, the spatially identical route determination unit 332, based on each piece of position information indicated by the measurement data, the above-described square area indicating the position information and the past The distance from the route r1 is calculated. For example, in the case of the estimated route r ₁₁ , any position information partially or entirely overlaps with the past route r 1, and thus the distance from the past route r 1 is 0 m. When the total of the distances is equal to or less than a threshold TH _d (TH _d is, for example, 200 m), the spatially identical route determination unit 332 determines that the route represented by the position information and the past route r ₁ are the same route. judge. In the case of the estimated route r ₁₁ , the spatially identical route determination unit 332 determines that the estimated route r ₁₁ and the past route r ₁ are the same route because the total distance is 0 m and is equal to or less than the threshold TH _d . In the case of the estimated route r ₂₁ , the distance between the square area indicating the position information (p ₂₁ , t ₂₁ ) and (p ₂₃ , t ₂₃ ) and the past route r1 is 200 m and 100 m, respectively. The spatially identical route determination unit 332 determines that the estimated route r ₂₁ and the past route r ₁ are not the same route because the sum (300 m) of these distances is greater than the threshold value TH _d .

  The spatially identical route determination unit 332 performs the above determination using route data indicating all past routes stored in the route storage unit 222. In this way, a path (this is referred to as “same path”) determined by the spatially identical path determination unit 332 to be the same as the estimated path from the past paths indicated by the path data stored in the path storage unit 222. Will be extracted. This same route is a past route whose distance from the estimated route is less than a threshold value. In this embodiment, the distance to the estimated route here is the sum of the distance between the square area indicated by the position information included in the estimated route and the past route. The route extraction unit 330 functions as route extraction means for performing such extraction when the terminal position is acquired by the acquisition unit 320. The route extraction unit 330 is a function realized by the cooperation of the control device 300 and the storage device 220 shown in FIG.

  The spatially identical route determination unit 332 supplies the route data indicating all the same routes to the route update unit 340 and the specifying unit 350 together with the measurement data used for this determination and the route data indicating the estimated route. In addition, when there is no identical route, that is, when it is determined that the estimated route is not the same as all past routes, the spatially identical route determination unit 332 communicates data indicating that the departure time cannot be extracted. The measurement data used for the determination and the route data indicating the estimated route are supplied to the route update unit 340 through the unit 310.

  Data is supplied to the route update unit 340 from the spatially same route determination unit 332 every predetermined time (5 minutes in this embodiment) until transmission of measurement data by the mobile terminal 10 is completed. If the route data indicating the same route is not included in the last supplied data among the series of data supplied in this way, the route update unit 340 obtains the route data indicating the supplied estimated route. Stored in the route storage unit 222. The route data stored in the route storage unit 222 will be route data indicating the past route thereafter. That is, the route data stored in the route storage unit 222 originally indicates the route represented by the measurement data.

On the other hand, when the last supplied data includes route data indicating the same route in the series of data, the route update unit 340 indicates the route data stored in the route storage unit 222. The same route (eg, past route r ₁ ) is updated using position information corresponding to the estimated route (eg, estimated route r ₁₁ ) indicated by the route data supplied together. Hereinafter, a case where the past route r ₁ is updated using position information included in the estimated route r ₁₁ will be described with reference to FIGS. 10 and 11. The route update unit 340 updates the past route r ₁ by a method using the position information included in the estimated route r ₁₁ that overlaps the position information included in the past route r ₁ (this is the first information). Thereafter, the past route r ₁ is updated by a method using non-overlapping methods (this is called a second updating method).

FIG. 10 is a diagram for explaining the first update method. In FIG. 10A, the position information (p ₁ , t ₁ ) and (p ₁₅ , t ₁₅ ) overlap, the position information (p ₂ , t ₂ ) and (p ₁₃ , t ₁₃ ) overlap, and the position information ( It is shown that p ₃ , t ₃ ) and (p ₁₁ , t ₁₁ ) overlap. Route update unit 340, when the direction of position information of the estimated route r ₁₁ which overlaps the previous position information of the route r ₁ may positioning error is small, that is small area of square area, the position of the last path r ₁ replacing the information in the position information of the estimated route r _11. In addition, the route update unit 340 adds the measurement time of the position information with the larger positioning error among the position information to the position information with the smaller positioning error.

FIG. 10B shows the past route r ₁ after the above replacement and addition have been performed. The route update unit 340 replaces the position information (p ₁ , t ₁ ) with (p ₁₅ , t ₁₅ ) and replaces the position information (p ₂ , t ₂ ) with (p ₁₃ , t ₁₃ ). The route updating unit 340, positional information (p _15, t _15), are added (p _13, t ₁₃₎ and (p _3, t ₃₎ in the measurement time t1, t ₂ and t _11, respectively. As a result, the position information was updated to (p ₁₅ , t ₁₅ , t ₁ ), (p ₁₃ , t ₁₃ , t ₂ ) and (p ₃ , t ₃ , t ₁₁ ). The past route r ₁ includes MBR _15-13 including position information (p ₁₅ , t ₁₅ , t ₁ ) and (p ₁₃ , t ₁₃ , t ₂ ), and position information (p ₁₃ , t ₁₃ , t ₂ ). ₂ ) and MBR _{13-3 including} (p ₃ , t ₃ , t ₁₁ ).

FIG. 11 is a diagram for explaining the second update method. FIG. 11A shows the past route r ₁ updated in FIG. 10 and the position information (p ₁₂ , t ₁₂ ) and (p ₁₄ , t ₁₄ ). These pieces of position information are not overlapped with the position information included in the past route r ₁ among the position information included in the estimated route r ₁₁ . The route update unit 340 identifies m pieces of position information (m is 2 for example) from the pieces of position information included in the past route r ₁ that are close to the terminal position of the position information (p ₁₂ , t ₁₂ ). Next, the route update unit 340 calculates the length of a line segment that connects the terminal position of each identified position information and the terminal position of the position information adjacent to the position information. In this example, position information (p ₃ , t ₃ , t ₁₁ ) and (p ₁₃ , t ₁₃ , t ₂ ) are specified, the length of a line segment L1 connecting these terminal positions, and position information (p ₁₃ , t _13, t ₂₎ and _{(p 15, t 15, t} 1) and the length of the line segment L2 (respectively l ₁ and l ₂ connecting the terminal position) is calculated. FIG. 11B shows a line segment for which the route update unit 340 calculates the length.

Subsequently, the route update unit 340 connects from the terminal position of each specified position information to the terminal position of the adjacent position information as described above via the terminal position of the position information (p ₁₂ , t ₁₂ ). The length of the line segment is calculated. Specifically, a line segment L3 connecting the terminal positions of the position information (p ₃ , t ₃ , t ₁₁ ) and (p ₁₂ , t ₁₂ ), the position information (p ₁₃ , t ₁₃ , t ₂ ) and ( the length of the p _12, t ₁₂ and the line segment L4 connecting the terminal position of) the position information _{(p 15, t 15, t} 1) and (p _12, line L5 connecting the terminal position of t ₁₂₎ Is calculated. The lengths of the line segments L3, L4, and L5 are assumed to be l ₃ , l _4, and l ₅ , respectively. Route update unit 340, when obtained by way of the terminal position of the position information (p _12, t _12), towards a change in the length of the line segment is smaller, adds the positional information (p _12, t _12). In this example, it is assumed that (l ₃ + l ₄ ) −l ₁ <(l ₄ + l ₅ ) −l ₂ . That is, the terminal of the position information (p ₁₃ , t ₁₃ , t ₂ ) from the terminal position of the position information (p ₃ , t ₃ , t ₁₁ ) via the terminal position of the position information (p ₁₂ , t ₁₂ ). The change in the length of the line segment is smaller when connected to the position. Therefore, the route update unit 340 adds the position information (p ₁₂ , t ₁₂ ) between the position information (p ₃ , t ₃ , t ₁₁ ) and the position information (p ₁₃ , t ₁₃ , t ₂ ). Similarly, the route updating unit 340 adds position information (p ₁₄ , t ₁₄ ) between the position information (p ₁₃ , t ₁₃ , t ₂ ) and the position information (p ₁₅ , t ₁₅ , t ₁ ). To do. FIG. 11C shows the past route r ₁ after the position information is added in this way.

By updating by the second updating method, the past route r ₁ is transferred to MBR _15-14 including position information (p ₁₅ , t ₁₅ , t ₁ ) and (p ₁₄ , t ₁₄ ), and position information. MBR _{14-13 including} (p ₁₄ , t ₁₄ ) and (p ₁₃ , t ₁₃ , t ₂ ), and positional information (p ₁₃ , t ₁₃ , t ₂ ) and (p ₁₂ , t ₁₂ ) are included. Updated to be represented by MBR _13-12 and MBR _12-3 containing location information (p ₁₂ , t ₁₂ ) and (p ₃ , t ₃ , t ₁₁ ). The route update unit 340 overwrites and stores the route data indicating the updated past route over the route data indicating the past route before update stored in the route storage unit 222.

  As described above, by updating using the first update method, the position information included in the past route is replaced with one with higher accuracy (with less positioning error). In addition, by performing the update by the second update method, the interval between the position information included in the past route is reduced, and the density of the position information representing the past route is increased. In other words, the position information is a data group for approximating a line called a past route. By the above update, the accuracy of those data groups is improved and the number of the data groups is increased, so that the approximated past route becomes closer to the actual route. That is, the past route indicated by the route data stored in the route storage unit 222 is updated closer to the actual route. As described above, the route update unit 340 and the route storage unit 222 cooperate to provide a route connecting the terminal positions acquired by the acquisition unit 320 from the start to the end of the movement of the mobile terminal 10, that is, the past. It functions as route storage means for storing routes.

  The route update unit 340 stores the user ID, the route ID indicating the route, and the number of passages in the use route storage unit 224. Specifically, in the series of data described above, when the last supplied data does not include route data indicating the same route, the route update unit 340 determines the estimated route indicated by the supplied route data. Is stored in the use route storage unit 224 together with the user ID indicated by the measurement data supplied together. That is, this estimated route is stored in the use route storage unit 224 as a new route. At this time, the route update unit 340 stores “1” as the number of passages in association with the route ID. On the other hand, when route data indicating the same route is included in the last supplied data, the route update unit 340 associates with the route ID of the same route already stored in the use route storage unit 224. Add 1 to the number of passes. In this way, each time the same route with respect to the estimated route when the movement of the mobile terminal 10 is extracted, the number of times of passage increases by 1 assuming that the mobile terminal 10 has passed the same route. As described above, the use route storage unit 224 functions as a number of times storage unit that stores a route and the number of times the route and the mobile terminal 10 have passed in association with each other.

  FIG. 12 is a table showing an example of information stored in the use route storage unit 224. In this table, information of “user ID”, “route ID”, and “passing count” is shown. Other information shown in this table will be described later. In this example, three “route IDs” “Z1”, “Z2”, and “Z3” are shown, and the “number of times of passage” associated with each is “10”, “6”, “2”. It has become. That is, among these routes, it is shown that the route Z1 is most used by the user. Further, since these routes are routes along which the mobile terminal 10 has moved, the “user ID” is both “001”.

Returning to FIG. The specifying unit 350 includes a destination predicting unit 351, a spatially overlapping station specifying unit 352, a getting-on / off station specifying unit 353, and a use route / transfer station specifying unit 354. The destination prediction unit 351 is supplied with route data indicating the same route and route data indicating the estimated route from the spatially same route determination unit 332.
When there are a plurality of route data indicating the supplied same route, the destination predicting unit 351 predicts which of the same routes indicated by the route data the mobile terminal 10 moves to the destination. . For example, when the route data indicating the routes Z1, Z2, and Z3 shown in FIG. 2 is supplied as the same route, the destination predicting unit 351 uses the route associated with each route ID in the use route storage unit 224. The destination of the same route with the highest number of times is predicted as the destination of the user who owns the mobile terminal 10. The destination here is the terminal position of the end point of the same route, and specifically, from the two terminal positions at the end of the same route, from the terminal position with the oldest measurement time in the estimated route. It is the remote terminal location. The destination predicting unit 351 supplies data indicating the predicted result, that is, route data indicating the same route toward the predicted destination, to the spatially overlapping station specifying unit 352 together with route data indicating the estimated route.

The spatially overlapping station specifying unit 352 is a unit that specifies a station that spatially overlaps with the same route indicated by the supplied route data. The spatial overlap station specifying unit 352 uses data stored in the traffic network storage unit 223 in order to perform this specification.
The traffic network storage unit 223 stores data indicating station information (referred to as station data). Specifically, the station data is data indicating a route ID, route name, station ID, station name, route order, adjacent station, station group ID, latitude, and longitude. For example, in the example shown in FIG. 2, the route ID is “A” (route ID of route A) or “B” (route ID of route B). Further, the station ID in that case is, for example, “A_A1” (the station ID of the A1 station on the route A) or “B_B1” (the station ID of the B1 station on the route B). The station group ID is assigned to a station that can be transferred to another route. For example, a station group ID “A3B1” is assigned to each of the A3 and B1 stations, and a station group ID “A7C1E1” is assigned to each of the A7, C1, and E1 stations. The traffic network storage unit 223 functions as a position storage unit that stores a station position, which is a station position. In the present embodiment, the station position is represented by latitude and longitude.

  The spatially overlapping station specifying unit 352 specifies a station in which the station position is included in the same route indicated by the supplied route data as a station that spatially overlaps the same route. Note that the spatially overlapping station specifying unit 352 determines that the station overlaps the area of a square centering on the station position (for example, one side is 200 m and each side is along the east-west direction and the north-south direction) and the route. May be specified as a spatially overlapping station. In addition, the spatial overlap station specifying unit 352 expresses a station as a polygonal area indicating an accurate spatial range, and when the same route overlaps with the area, specifies the station as a spatially overlapping station. May be. The spatial overlap station specifying unit 352 supplies the station data indicating the specified station to the boarding / exiting station specifying unit 353 together with the route data supplied from the destination prediction unit 351.

  When there are a plurality of supplied station data, the boarding / exiting station specifying unit 353 specifies the boarding station and the getting-off station from the stations indicated by the station data. The boarding station here is a station where the user first gets on the train on the same route, and the getting-off station is a station where the user finally gets off the train on the same route. Specifically, the getting-on / off-station specifying unit 353 specifies the station closest to the starting point of the same route as the boarding station, and specifies the station closest to the end point of the same route as the getting-off station. Here, the starting point of the same route is the one at the end opposite to the above-mentioned end point out of the two terminal positions at the end of the same route.

  In addition, the boarding / alighting station specifying unit 353 uses the distance from the start point (or end point) as a usable distance, which is a distance obtained by adding a predetermined distance to the distance between the start point (or end point) of the same route and the nearest station. A station smaller than the possible distance may be specified as a boarding station (or a stop station). Moreover, when starting movement from the starting point along the same route indicated by the route data, the boarding / exiting station specifying unit 353 first identifies a station that overlaps the same route as a boarding station, and finally selects a station that overlaps the same route. It may be specified as a stop station. The getting-on / off-station specifying unit 353 adds a flag indicating that it has been specified to the specified boarding station and station data of the getting-off station, along with the station data and the route data supplied from the spatially overlapping station specifying unit 352, and the route used -Supply to transfer station specific part 354.

  Further, as shown in FIG. 12, the boarding station specifying unit 353 stores the specified boarding station and the ID of the boarding station (referred to as “boarding station ID” and “boarding station ID”) in the use route storage unit 224. . In FIG. 12, route IDs “Z1”, “Z2”, and “Z3” are associated with “boarding station ID” of “A_A1”, and “B_B3”, “ “Get-off station IDs” of “C_C3” and “D_D5” are associated with each other. In this manner, the boarding / exiting station specifying unit 353 stores the station ID of the specified boarding station as the boarding station ID in the use route storage unit 224 in association with the route ID of the route indicated by the supplied route data. The station ID of the exit station is stored in the use route storage unit 224 as the exit station ID.

  The used route / transfer station specifying unit 354 uses a route (hereinafter referred to as “used route”) used when moving from the boarding station specified by the getting-on / off station specifying unit 353 to the getting-off station, and the used route. The station (hereinafter referred to as “transfer station”) where the train is changed when the train is transferred is identified. The use route / transfer station specifying unit 354 uses a route search algorithm such as A * (A-star), for example, on the train route from the boarding station to the getting-off station specified by the upper and lower car station specifying unit 353. In addition, the route having the minimum total cost is detected from the routes passing through the stations specified by the spatially overlapping station specifying unit 352. In this way, by using the set of stations specified by the spatially overlapping station specifying unit 352, the time required for the search can be reduced by narrowing the search range as compared with the case where the route is searched for all stations as a range. It can be shortened. Then, the used route / transfer station specifying unit 354 specifies the used route used in the detected route. The used route / transfer station specifying unit 354 stores data indicating the specified used route (for example, route ID) in the used route storage unit 224 as shown in FIG. In FIG. 12, “use route IDs” “A, B”, “A, C” and “A, B, D” are associated with the route IDs “Z1”, “Z2” and “Z3”. It has been.

  Moreover, when there are a plurality of specified use routes, the use route / transfer station specifying unit 354 specifies a transfer station at which transfer of the use routes is performed. Specifically, the use route / transfer station specifying unit 354 specifies a station having the same station group ID as a transfer station among the stations stored in the traffic network storage unit 223 in association with the specified use route. To do. As described above, the specifying unit 350 includes the station positions stored in the traffic network storage unit 223 among the plurality of stations included in the same route extracted by the route extraction unit 330 and along the same route. When moving, it functions as a specifying means for specifying a station (boarding station or transfer station) where the user gets on the train. In addition, when there are a plurality of identical routes extracted by the route extraction unit 330, the specifying unit 350 determines the number of times that the mobile terminal 10 has passed the station position stored in the traffic network storage unit 223 in the same route. Identify the stations that are included in the most common route. The specifying unit 350 uses the number of passages stored in association with the same route by the use route storage unit 224 as the number of times of passage here. The identifying unit 350 is a function realized by the control device 300 and the storage device 220 shown in FIG. The use route / transfer station specifying unit 354 stores the transfer station ID indicating the specified transfer station in the use route storage unit 224 as shown in FIG.

  In FIG. 12, “transfer station ID” of “A_A3 = B_B1”, “A_A7 = C_C1” and “A_A3 = B_B1, B_B4 = D_D3” is associated with the route IDs “Z1”, “Z2”, and “Z3”. It is associated. This “transfer station ID” represents a transfer station as a transfer source and a transfer station as a transfer destination. If “A_A3 = B_B1”, the A3 station indicated by “A_A3” is the transfer source station, and the B1 station indicated by “B_B1” is the transfer destination station. The use route / transfer station specifying unit 354 stores the data indicating the use route and the transfer station in the use route storage unit 224 as described above, and, for example, the “route ID” associated with the stored data and its data The time extraction unit 360 is notified that storage has been performed.

  The time extraction unit 360 includes a standard transfer time determination unit 361 and a transfer station / transfer station departure time specifying unit 362. The standard transfer time determination unit 361 is notified from the use route / transfer station specifying unit 354. When the standard transfer time determination unit 361 receives this notification, the standard transfer time determination unit 361 out of the time required for transfer at the transfer station corresponding to the notified route ID (hereinafter referred to as “transfer time”) is a standard one. (Hereinafter referred to as “standard transfer time”). The transfer time here is the time from the arrival of the transfer-source train at the transfer station to the departure of the transfer-destination train from the transfer station. The transfer time varies depending on the walking speed of the user who performs the transfer, the position of the vehicle to be boarded, and the time zone (a time zone with a large number of trains and a time zone with a small number of trains). The standard transfer time is a transfer time determined such that the distance from other transfer times is as small as possible. The standard transfer time determination unit 361 determines this standard transfer time using data stored in the timetable storage unit 225, for example.

  The timetable storage unit 225 is a time storage unit that stores a station ID of each station and a plurality of departure times (so-called departure times in a timetable) at which trains depart from the stations in association with each other. The timetable storage unit 225 also stores the time when the train arrives at the station (referred to as arrival time) in association with the station ID of each station. These departure time and arrival time are stored in advance in the timetable storage unit 225 based on information provided by the company that operates the train. Further, the timetable storage unit 225 stores the transfer travel time corresponding to each transfer station in association with the transfer station ID. This transfer travel time is, for example, the time it takes for an adult to normally walk from the platform of A3 station to the platform of B1 station (for example, at 60 m / min) if the transfer is from station A3 to station B1. It is.

  The timetable storage unit 225 stores transfer movement times of 5 minutes, 10 minutes, and 3 minutes in association with transfer station IDs “A_A3 = B_B1”, “A_A7 = C_C1”, and “B_B4 = D_D3”. . The standard transfer time determination unit 361 determines the transfer movement time associated with the transfer station ID described above and stored in the timetable storage unit 225 as the standard transfer time corresponding to the transfer station ID. The standard transfer time determination unit 361 supplies data representing the determined standard transfer time to the transfer station / transfer station departure time specifying unit 362 in association with the transfer station ID and the route ID.

  The transfer station / transfer station departure time specifying unit 362 uses the data supplied from the standard transfer time determining unit 361 and the data stored in the use route storage unit 224 and the timetable storage unit 225 to specify the specifying unit 350. The departure time at the boarding station and the transfer station specified by is specified. Specifically, the boarding station / transfer station departure time specifying unit 362 starts from the current time from the boarding station (for example, A1 station) corresponding to the supplied route ID (for example, Z1) to the stop station (for example, B3 station). When departing, the departure time at the boarding station A1 and the departure time at the transfer station B1 are specified.

  FIG. 13 is a diagram for explaining the departure time specified by the departure / departure station departure time specifying unit 362. FIG. 13 shows an example of the departure time of a train to be boarded when moving along the route Z1. In this description, it is assumed that the current time is 8:59. In FIG. 13, the departure times of the A1 and B1 stations and the arrival times of the A3 and B3 stations are shown for eight trains after 9 o'clock. The departure time of the A1 station is every 5 minutes, such as “9:00”, “9:05”, “9:10”, and so on. Since the current time is 8:59, the departure station / transfer station departure time specifying unit 362 is the departure time after the current time among the departure times of the A1 station, which is the boarding station, and close to the current time The three departure times are identified in order. In this case, the boarding / transfer station departure time specifying unit 362 specifies “9:00”, “9:05”, and “9:10” indicated by the arrow M1 in FIG. 13 as the departure time of the boarding station.

  Next, the boarding station / transfer station departure time specifying unit 362 specifies the arrival time at which the train departing from the boarding station at the specified departure time arrives at the A3 station as the transfer station. In this example, the boarding / transfer station departure time specifying unit 362 specifies “9:11”, “9:16”, and “9:21” indicated by the arrow M2 as arrival times at the transfer station. Subsequently, the transfer station / transfer station departure time specifying unit 362 specifies the departure time of a train departing from the B1 station which is a transfer station. The transfer station / transfer station departure time specifying unit 362 is, for example, the standard transfer time (5 minutes) later than the middle arrival time (in this case, “9:16”) among the three arrival times of the specified A3 station. The departure time closest to this time (in this case, “9:24”) is specified after the time (that is, 9:21). The departure / departure station departure time specifying unit 362 specifies departure times before and after the specified departure time of “9:24” (in this case, “9:19” and “9:29”). Thus, the departure time indicated by the arrow M3 is specified. Next, the departure station / transfer station departure time specifying unit 362 has three arrival times (indicated by an arrow M4 indicated by an arrow M4) at which the train departing from the B1 station arrives at the B3 station which is the departure station at the three specified departure times. 31 ”,“ 9:36 ”, and“ 9:41 ”) are specified as arrival times at the getting-off station, respectively.

  As described above, the time extraction unit 360 is the same extracted by the route extraction unit 330 from a plurality of departure times stored in the timetable storage unit 225 in association with the boarding station and the transfer station specified by the specifying unit 350. It functions as time extraction means for extracting the departure time of the train on which the user gets when moving along the route. Here, the movement along the same route is a movement in which boarding at the boarding station is started after the time when the boarding station / transfer station departure time specifying unit 362 specifies the departure time. In addition, when the mobile terminal 10 moves along the same route extracted by the route extraction unit 330, the time extraction unit 360 changes the time required for the change in a plurality of ways. A plurality of departure times are extracted respectively. The time extraction unit 360 is a function realized by the control device 300 and the storage device 220 shown in FIG.

The departure station / transfer station departure time specifying unit 362 associates the specified departure station and departure time at the transfer station, the station IDs of these stations, and the route IDs of the trains that depart at these departure times. The data is supplied to the communication unit 310. Hereinafter, this data indicating the information including the departure time is referred to as “departure time data”. Moreover, the transfer station / transfer station departure time specifying unit 362 sets the arrival times at the specified transfer station and the getting-off station, the station IDs of these stations, and the route IDs of the train lines that arrive at these arrival times, respectively. The associated data is supplied to the communication unit 310. Hereinafter, this data indicating information including the arrival time is referred to as “arrival time data”.
The communication unit 310 functions as a transmission unit that transmits the departure time data and arrival time data supplied from the boarding / transfer station departure time specifying unit 362 to the mobile terminal 10.

[Operation]
The departure time notification system 1 performs the notification process described above based on the above configuration. Hereinafter, the operation of each device in the notification process will be described.
FIG. 14 is a sequence chart showing operations performed by the mobile terminal 10 and the server device 20 in the notification process. When the user performs a predetermined operation on the operation device 120 illustrated in FIG. 3, the mobile terminal 10 starts the notification processing program (step S <b> 10). When the notification processing program is activated, the mobile terminal 10 first generates one set of measurement data as described above (step S11). Step S11 is an operation performed by the measurement data generation unit 101 shown in FIG. Next, when it is determined that the mobile terminal 10 is moving based on the generated set of measurement data, the mobile terminal 10 transmits to the server device 20 the measurement time of the measurement data that is newer ( Step S12). Step S <b> 12 is an operation performed by the movement stillness determination unit 102 and the communication unit 103 in cooperation.

  The server device 20 starts the departure time extraction process when the measurement data is received for the first time in step S12 (step S13). The operation in step S13 is performed only when measurement data is received for the first time. The departure time extraction process is a process in which the server device 20 extracts information such as a departure time based on measurement data. The server device 20 performs this departure time extraction process (step S30), and transmits the departure time data and arrival time data described above to the mobile terminal 10 (step S14). Step S14 is an operation performed by the communication unit 310 shown in FIG. When receiving the departure time data and arrival time data in step S14, the mobile terminal 10 displays the departure time indicated by these departure time data and the arrival time indicated by the arrival time data on the display surface (step S15). Step S15 is an operation performed by the notification unit 104.

  Subsequently, the mobile terminal 10 determines whether or not an operation for terminating the notification processing program (referred to as an end operation) has been performed (step S16), and if it has not been performed (step S16: NO) ), It is determined whether or not a predetermined time (5 minutes in the present embodiment) has elapsed since the operation of step S11 was performed (step S17). If the mobile terminal 10 determines that the predetermined time has not elapsed (step S17: NO), it performs the operation of step S16 again, and if it determines that the predetermined time has elapsed (step S17: YES). Then, the operation of step S11 is performed again. Step S17 is an operation performed by the measurement data generation unit 101 shown in FIG. In this way, the mobile terminal 10 generates measurement data every predetermined time and transmits the generated measurement data to the server device 20 until the end operation described above is performed.

  If the mobile terminal 10 determines that the termination operation has been performed (YES) in step S16, the mobile terminal 10 terminates the notification processing program (step S18), and sends data indicating that the program has been terminated to the server device 20. Transmit (step S19). Upon receiving this data, the server device 20 ends the departure time extraction process (step S20). After step S13, the server device 20 repeatedly executes the departure time extraction process until the process ends in step S20. Accordingly, the operations in steps S14 and S15 are also repeatedly executed. In step S12, measurement data may not be transmitted when it is determined that the mobile terminal 10 is stationary. However, the departure time extraction process is performed regardless of whether or not the measurement data is received in step S12. It has become. The departure time extraction process will be described in detail with reference to FIGS. 15 to 18.

  FIG. 15 is a flowchart illustrating an operation performed by the server device 20 in the departure time extraction process. The server device 20 first acquires the terminal position indicated by the latest one of the positional information of the mobile terminal 10 held (that is, stored in the storage device 220) (step S31). Step S31 is an operation performed by the acquisition unit 320 illustrated in FIG. Next, the server device 20 performs route extraction processing using the acquired terminal position (step S32). Step S32 is an operation performed by the route extraction unit 330.

  FIG. 16 is a flowchart illustrating an operation performed by the server device 20 in the route extraction process. First, the server apparatus 20 estimates a route along which the mobile terminal 10 moves based on the acquired terminal position (step S321). Step S321 is an operation performed by the route estimation unit 331. Next, the server device 20 compares any of the routes traveled by the mobile terminal 10 in the past with the route estimated in step S321, and determines whether these are the same (step S322). The route traveled by the mobile terminal 10 in the past is a route indicated by route data stored in the route storage unit 222.

  Then, the server device 20 determines whether there is data indicating an undetermined path among the path data stored in the path storage unit 222 (that is, whether there is an undetermined path) (step). S323). If the server apparatus 20 determines YES in step S323, the server apparatus 20 returns to step S322 to perform the operation. If NO, the server 20 ends the route extraction process. Steps S322 and S323 are operations performed by the spatially same path determination unit 332. Thereby, the route determined to be the same as the route estimated in step S321 is extracted from all the past routes.

After performing the route extraction process in step S32, the server device 20 performs a station / route identification process (step S33).
FIG. 17 is a flowchart illustrating an operation performed by the server device 20 in the station / route identification process. First, when there are a plurality of routes extracted by the route extraction process, the server device 20 predicts which route will be moved to the destination (step S331). Step S331 is an operation performed by the destination prediction unit 351 shown in FIG. Next, the server device 20 specifies a station that spatially overlaps the predicted route (step S332). Step S332 is an operation performed by the spatial overlap station specifying unit 352.

  Subsequently, when there are a plurality of stations identified in step S332, the server device 20 identifies the boarding station and the getting-off station from those stations (step S333). Step S333 is an operation performed by the boarding / alighting station specifying unit 353. And the server apparatus 20 specifies the use route used by the path | route which moves from the boarding station specified in step S333 to a getting-off station, and when there are two or more specified use routes, the transfer station which transfers those use routes is specified. Specify (step S334). Step S334 is an operation performed by the use route / transfer station specifying unit 354. After performing the operation of step S334, the server device 20 ends the station / route identification processing.

The server device 20 performs time extraction processing after performing the station / route identification processing in step S33 (step S34).
FIG. 18 is a flowchart illustrating an operation performed by the server device 20 in the time extraction process. First, the server device 20 determines a standard transfer time when a transfer is performed at the transfer station specified in the station / route specifying process (step S341). Step S341 is an operation performed by the standard transfer time determination unit 361. Then, the server device 20 specifies the boarding station specified in the station / route specifying process, the departure time at the transfer station, and the like (step S342), and ends the time extraction process. Step S342 is an operation performed by the boarding station / transfer station departure time specifying unit 362.

  The server device 20 transmits the departure time data indicating the departure time specified in the time extraction process in step S34 and the arrival time data indicating the arrival time to the mobile terminal 10 (step S35). Step S35 is an operation performed by the communication unit 310. Next, after performing the operation of step S31, the server device 20 determines whether or not a state in which measurement data is not received (non-reception state) has continued for a certain time (1 hour in the present embodiment) or more. (Step S36) When it is determined that the operation has not continued for a certain time (Step S36: NO), it is determined whether or not a predetermined time (5 minutes in the present embodiment) has elapsed since the operation of Step S31 was performed. (Step S37). When it is determined that the predetermined time has not elapsed (step S37: NO), the server device 20 performs the operation of step S36 again. When it is determined that the predetermined time has elapsed (step S37: YES), the server device 20 proceeds to step S31. Perform the operation again. In this way, the server device 20 performs the departure time extraction process at predetermined time intervals until the unreceived state continues for a certain time or more. In this embodiment, the server device 20 performs the departure time extraction process every predetermined time as described above. However, the server apparatus 20 may perform the departure time extraction process in response to an explicit departure time extraction request from the mobile terminal 10. Good.

  In step S31, if the measurement data is transmitted from the mobile terminal 10 every predetermined time, the terminal position and the measurement time indicated by the transmitted measurement data are acquired, and it is determined that the mobile terminal 10 is stationary. If the measurement data is not transmitted, the terminal position and the measurement time indicated by the measurement data transmitted last are acquired before it is determined to be stationary. If the server device 20 determines in step S36 that the unreceived state has continued for a certain period of time (YES), the departure time extraction process ends. As described above, the server device 20 notifies the user of the departure time and the arrival time for a certain period of time after the user finishes moving, but does not perform the notification after the certain period of time has elapsed. .

Information such as the departure time indicated by the departure time data transmitted in step S35 and information such as the arrival time indicated by arrival time data are displayed on the display screen of the mobile terminal 10 in step S15 shown in FIG.
FIG. 19 is a diagram illustrating an example of an image representing information such as a departure time displayed by the mobile terminal 10. On this display surface, images from G1 to G10 are displayed. The image G1 is a character string “A1 station → B3 station”, and represents that the train moves from the boarding station to the getting-off station. The image G2 is a character string of “A1 station”, “A3B1 station”, and “B3 station”, and represents a boarding station, a transfer station, and a stop station, respectively. The image G3 is character strings “route A” and “route B”, and represents a route from the transfer station to the transfer station and a route from the transfer station to the stop station.

  The image G4 is a character string “9:00”, “9:05”, and “9:10”, and represents the departure time at the boarding station (A1 station). The image G5 is character strings “9:11”, “9:16”, and “9:21”, and represents arrival times at the transfer station (A3 station). The image G6 is character strings “9:19”, “9:24”, and “9:29”, and represents the departure time at the transfer station (B1 station). The image G7 is a character string of “9:31”, “9:36”, and “9:41”, and represents arrival times at the getting-off station (B3 station).

  The image G8 represents character strings “3 minutes”, “8 minutes”, and “13 minutes”, and arrows superimposed on those character strings. These arrows extend from the character string “9:16” in the image G5 to the three character strings in the image G6. The image G8 represents the transfer time when the transfer indicated by the arrow is performed at the transfer station (A3B1 station). For example, if you get off the train that arrives at “9:16” at A3 station and you get on a train that leaves at “9:24” from B1 station, the transfer time is expressed as “8 minutes”. Yes. Thereby, the user can know whether it is better to run quickly or to walk slowly when changing at the A3B1 station. For example, when one train is delayed for some shopping, the user can also know how many minutes there are until the next train departure time.

  The image G9 has an arrow extending from a character string “9:05” of the image G4 toward a character string “9:16” of the image G5, and three character strings of the image G6 to three character strings of the image G7. There are three arrows that extend respectively. The image G10 is a character string of “required time on the arrow route”, “26 minutes”, “31 minutes”, and “36 minutes”, and moves from the boarding station to the getting-off station as indicated by the arrows in the images G8 and G9. It shows the time required for each. For example, if you get on a train that departs A1 station at "9:05" and get off at a train that arrives at B3 station at 9:36, it shows that the required time is 31 minutes. As a result, the user can know the difference in required time between when the transfer is made quickly at the transfer station and when the transfer is performed slowly.

Returning to FIG. When the server device 20 finishes the departure time extraction process in step S20, the server apparatus 20 performs a route storage process (step S40).
FIG. 20 is a flowchart illustrating an operation performed by the server device 20 in the path storage process. The server device 20 determines whether there is an identical route that matches the route estimated last in the departure time extraction process (step S41). Specifically, the server device 20 includes route data indicating the same route in the last supplied data among a series of data supplied from the spatially same route determination unit 332 to the route update unit 340 shown in FIG. If it is not included, it is determined that there is no identical route. When it is determined that the same route exists (step S41: YES), the server device 20 updates the same route as described above (step S42), and when it is determined that there is no same route (step S41: NO). ) The last estimated route is stored as a new past route (step S43), and the route storage process is terminated. This route storage process is an operation performed by the route update unit 340 and the route storage unit 222 in cooperation.

  According to the departure time notification system 1 of the present embodiment, if the user activates the notification processing program as described with reference to FIG. 14, the user performs an operation of inputting a character string representing the boarding station or the getting-off station. Even without this, it is possible to know information such as the departure time, transfer time, and required time described above. These pieces of information are displayed on the mobile terminal 10 by the departure time data transmitted from the server device 20. That is, the server device 20 notifies the user of information such as the departure time via the mobile terminal 10 by transmitting departure time data. From the above, the server device 20 can reduce the burden of operations performed by the user on the mobile terminal 10 when notifying the user of information such as the departure time.

[Second Embodiment]
In the first embodiment described above, the departure time notification system 1 determines the transfer travel time corresponding to each transfer station stored in the timetable storage unit 225 as the standard transfer time. In this embodiment, the departure time notification system 1 The standard transfer time is determined based on the transfer time calculated from the route. For this calculation, a transfer time calculation unit 370a shown in FIG. 5 is used. The transfer time calculation unit 370a calculates the time (transfer time) required to transfer trains on the past route. In the transfer time calculation unit 370a, the use route / transfer station specifying unit 354 stores the data indicating the use route and the transfer station in the use route storage unit 224, and the route ID associated with the stored data. Will be notified. Hereinafter, a case where the route ID “Z1” is notified will be described as an example. The transfer time calculation unit 370a first refers to the measurement data storage unit 221 and extracts the terminal position and measurement time measured in the past in the route indicated by the notified route ID.

  FIG. 21 is a diagram illustrating an example of terminal positions and measurement times in the past route Z1. In FIG. 21, eight terminal positions from H1 to H8 are shown. The terminal position H1 has a measurement time of 8:57. The subsequent terminal positions are measured every 5 minutes after 8:57, and the terminal position H8 has a measurement time of 9:32. Next, the transfer time calculation unit 370a has a distance between the A3B1 station and the first group (in this example, H1, H2, and H3) in which the distance from the A3B1 station gradually decreases among these terminal positions. The second group (also H4 and H5) and the third group (also H6, H7 and H8) in which the distance from the A3B1 station gradually increases are classified.

  The transfer time calculation unit 370a specifies the terminal position of the first group having the shortest distance from the A3B1 station (in this example, H3) as the position immediately before the transfer station (referred to as “immediate position”). Among the terminal positions of the third group, the one having the shortest distance from the A3B1 station (also H6) is specified as the position immediately after the transfer station (referred to as “immediate position”). And the transfer time calculation part 370a puts between the measurement time (9:07) of the last position among the arrival times of A3 station, and the measurement time (9:12) after that, It is specified as the time when the user arrived at the A3 station in the past transfer.

  FIG. 22 is a diagram illustrating an example of arrival time and departure time at the transfer station A3B1. The transfer time calculation unit 370a specifies 9:11 between 9:07 and 9:12 as the time when the user arrives at the A3 station. Moreover, the transfer time calculation part 370a is sandwiched between the measurement time (9:22) immediately after the departure time of the B1 station and the measurement time (9:17) immediately before it. Is specified as the time when the user departed from the B1 station in the past transfer. Then, the transfer time calculation unit 370a calculates the time (in this example, 8 minutes) between these identified times (the time when the user arrives and the time when the user leaves) as the transfer time in this transfer. .

  The transfer time calculation unit 370a calculates transfer times for all terminal positions and measurement times measured in the past on the route Z1. Then, the transfer time calculating unit 370a calculates the average of the calculated transfer times as the transfer time at the A3B1 station on the route Z1. In this case, the transfer time calculation unit 370a may average the transfer times for each time zone of the measurement time. As described above, the transfer time calculation unit 370 a functions as a calculation unit that calculates the transfer time in the route extracted by the route extraction unit 330. The transfer time calculation unit 370a performs this calculation based on the measurement time stored in the measurement data storage unit 221 in association with the terminal position included in the route. The transfer time calculation unit 370a is a function realized by cooperation of the control device 300 and the storage device 220 shown in FIG. The transfer time calculation unit 370a supplies data indicating the calculated transfer time to the standard transfer time determination unit 361. The standard transfer time determination unit 361 determines the transfer time indicated by the data supplied from the transfer time calculation unit 370a as the standard transfer time. As a result, the time extraction unit 360 determines the transfer time calculated by the transfer time calculation unit 370a when the mobile terminal 10 moves along the same route extracted by the route extraction unit 330. The departure time when extracting the time required for transfer is extracted.

  As described above, the transfer time varies depending on the walking speed of the user, the position of the vehicle on which the user gets, the time zone, and the like. On the other hand, for the same user, the walking speed often does not change in many cases, and if the route is frequently used for commuting, attending school, etc., the position of the vehicle on which the user rides is also generally common. According to the present embodiment, the server device 20 calculates the transfer time in the past route, and determines the average of the calculated transfer times as the standard transfer time, so when any user determines the same standard transfer time. In comparison, the time closer to the transfer time when the user is transferring on the route can be determined as the standard transfer time. As a result, the server device 20 can notify the user of the departure time of the transfer destination train that is more likely to be used by the user than when the same standard transfer time is used by any user. Also, by calculating the transfer time for each time zone, for example, the commuting / commuting time zone may take more time to transfer because the station is more crowded than other time zones, but in such cases Even if it exists, it becomes possible to notify information with an appropriate transfer time. In addition, if the transfer time calculated by the transfer time calculation unit 370a is small, it is easily affected by an abnormal value such as accidentally running or shopping at the time of transfer, but such an increase in the number of times the route passes, The influence of outliers is reduced. That is, as the number of times the user uses the route increases, the possibility that the user uses a train that starts at the departure time notified by the server device 20 can be increased.

[Third Embodiment]
In the second embodiment described above, the departure time notification system 1 determines the standard transfer time based on the transfer time calculated from the past route, but in this embodiment, the departure time notification system 1 uses the attribute of the user who owns the mobile terminal 10 as an attribute. Based on this, the standard transfer time is determined. For this determination, the attribute data generation unit 105b and the attribute data acquisition unit 380b shown in FIG. 5 are used. The storage device 130 of the mobile terminal 10 stores data indicating user attributes. The user attributes here are the user's age (or date of birth), gender, address, and the like.

  The attribute data generation unit 105b is supplied with data indicating that from the movement / stillness determination unit 102 that has determined that the mobile terminal 10 is moving. When this data is supplied, the attribute data generation unit 105b generates attribute data (hereinafter referred to as “attribute data”) indicating a predetermined attribute among the attributes described above. The predetermined attributes here are age and sex. The attribute data generation unit 105 b supplies the generated attribute data to the communication unit 103. The communication unit 103 transmits the supplied attribute data to the server device 20 together with the measurement data supplied from the moving stillness determination unit 102. The communication unit 310 of the server device 20 supplies the received attribute data to the attribute data acquisition unit 380b.

  The attribute data acquisition unit 380b is an attribute data acquisition unit that acquires attribute data. In the present embodiment, the attribute data acquisition unit 380b acquires attribute data supplied from the communication unit 310. Note that the attribute data acquisition unit 380b may transmit request data for requesting attribute data to the mobile terminal 10 via the communication unit 310 when only measurement data is transmitted from the mobile terminal 10, for example. In this case, in the mobile terminal 10, the request data is supplied to the attribute data generation unit 105b via the communication unit 103, and the attribute data generated by the attribute data generation unit 105b according to the request for the request data is transmitted via the communication unit 103. It is transmitted to the server device 20. The attribute data acquisition unit 380b acquires the attribute data by receiving the attribute data via the communication unit 310. When the attribute is stored in the external device instead of the mobile terminal 10, the attribute data acquisition unit 380b may acquire the attribute data by transmitting request data to the external device. The attribute data acquisition unit 380b is a function realized by the control device 300 and the communication device 210 illustrated in FIG. The attribute data acquisition unit 380b supplies the acquired attribute data to the standard transfer time determination unit 361.

The standard transfer time determination unit 361 changes the standard transfer time based on the attribute indicated by the attribute data supplied from the attribute data acquisition unit 380b. The standard transfer time determination unit 361 performs this change using, for example, the following table.
FIG. 23 is a diagram illustrating an example of a table used by the standard transfer time determination unit 361. In this table, numerical values from “0.5” to “1.3” for each of the combinations of “male” and “female” with seven ages from “10s” to “70s and above” Are associated. For example, “1.1” for “male” for “10” and “0.8” for “female” for “50”. The standard transfer time determination unit 361 determines, as the standard transfer time, the attribute indicated by the attribute data and the numerical value corresponding to this table, excluding the transfer movement time stored in the timetable storage unit 225. For example, if the transfer travel time is 10 minutes and the attribute is “male” of “teens”, 10 minutes ÷ 1.1≈9 minutes is determined as the standard transfer time.

The standard transfer time determined as described above is a time according to the attribute indicated by the attribute data acquired by the attribute data acquisition unit 380b. As described above, the time extraction unit 360 determines that the attribute data acquired by the attribute data acquisition unit 380b is transferred when the mobile terminal 10 moves along the same route extracted by the route extraction unit 330. The departure time is extracted when the transfer time corresponding to the attribute shown is the time required for the transfer.
According to the present embodiment, since the server device 20 determines the standard transfer time according to the user's attributes, the user can follow the route in comparison with the case where any user determines the same standard transfer time. A time closer to the transfer time when transferring is determined as the standard transfer time. In addition, the server device 20 can determine the standard transfer time without being affected by the number of times the user has passed the route, the above-described abnormal value, or the like by using the user attribute.

[Fourth Embodiment]
In the first embodiment described above, the departure time notification system 1 predicts the destination based on the number of times the route has passed in the past, but in this embodiment, the departure time notification system 1 predicts the destination based on information representing the user's schedule. For this prediction, the schedule data extraction unit 106c and the schedule data acquisition unit 390c shown in FIG. 5 are used. The storage device 130 of the mobile terminal 10 stores a program for managing a user's schedule (schedule). When the control device 110 executes this program and the user operates the operation device 120, the storage device 130 stores data indicating the user's schedule (hereinafter referred to as “schedule data”). Specifically, the schedule data is a character string indicating the action scheduled by the user, the place where the schedule is executed, the time when the schedule is executed (hereinafter referred to as “schedule time”), and the like. The format of the schedule data is determined, and the position of the character string on the data indicates whether the character string represents an action, a place, or a scheduled time.

  The schedule data extraction unit 106c is supplied with data indicating that from the moving / still state determination unit 102 that has determined that the mobile terminal 10 is moving. When this data is supplied, the schedule data extraction unit 106c has a schedule time indicated by the schedule data in the schedule data described above after the current time, and a predetermined time (for example, 3 hours) from the current time. ) Is extracted before the elapsed time. For example, if the current date and time is 9:00 on May 1, the schedule data extraction unit 106c extracts schedule data including the date and time from 9:00 to 12:00 on May 1. The schedule data extracted in this way is data indicating a user's schedule in the latest three hours. The schedule data extraction unit 106 c supplies the extracted schedule data to the communication unit 103.

  The communication unit 103 transmits the supplied schedule data to the server device 20 together with the measurement data supplied from the moving stillness determination unit 102. The communication unit 310 of the server device 20 supplies the received schedule data to the schedule data acquisition unit 390c. The schedule data acquisition unit 390c functions as a schedule acquisition unit that acquires the location and the schedule time indicated by the supplied schedule data. The scheduled data acquisition unit 390c is a function realized by the control device 300 and the communication device 210 illustrated in FIG. The schedule data acquisition unit 390c supplies the acquired schedule data to the destination prediction unit 351. The destination prediction unit 351 performs the above-described destination prediction using the position of the location indicated by the schedule data supplied from the schedule data acquisition unit 390c. In order to perform this prediction, the storage device 220 of the server device 20 stores in advance a character string representing a location and the location of the location in association with each other.

When there are a plurality of route data supplied, the destination prediction unit 351 has the smallest distance from the end point of the route indicated by each route data to the position of the place indicated by the schedule data and is equal to or less than the threshold value Is predicted as the destination. Hereinafter, a case where route data indicating the routes Z1, Z2, and Z3 shown in FIG. 2 is supplied and the threshold value is set to 500 m will be described as an example. The destination prediction unit 351 calculates the distance between the position of the place indicated by the schedule data and the positions of the destinations Y1, Y2, and Y3 in each route, that is, the terminal positions of the end points of the routes Z1, Z2, and Z3. If the distances are 100 m, 4 km, and 5 km, respectively, the destination predicting unit 351 predicts Y1 having the smallest calculated distance and the distance being equal to or less than the threshold (500 m) as the destination. The destination prediction unit 351 notifies the mobile terminal 10 via the communication unit 310 that the departure time could not be extracted when all the calculated distances are larger than the threshold. When the destination predicting unit 351 predicts the destination as described above, the specifying unit 350 sets the scheduled time that is later than the current time and closest to the current time among the scheduled times acquired by the scheduled data acquiring unit 390c. Stations included in the same route to the associated location are specified.
According to the present embodiment, the server device 20 can notify the user of the departure time of the train on the route that passes when the user performs an action according to the schedule.

[Fifth Embodiment]
In the first embodiment described above, the departure time notification system notifies the user of the use route, departure time, and arrival time at each station specified by the specifying unit 350. In this embodiment, in addition to these, the vehicle is normal. Notifies the operation status of the route used, such as whether it is operating on the street or whether there is a delay in the departure time. In addition, the operation status includes thinning-out operation that reduces the number of vehicles, cancellation of mutual entry between different routes, and transfer transportation. These operating conditions are mainly provided by railway companies that operate the vehicles on the route.

  FIG. 24 is a diagram showing the configuration of the departure time notification system 1d in the present embodiment. The departure time notification system 1 d includes an operation status distribution server device 30. The operation status distribution server device 30 is operated by a railway company, and transmits data indicating the operation status of the vehicle of the railway company (referred to as “operation status data”) to a device defined by a contract or the like. If there are a plurality of railway companies for the route targeted by the departure time notification system, there will be a plurality of operation status distribution server devices 30. In this embodiment, there is one railway company for the target route. That is, the case where there is one operation status distribution server device 30 will be described as an example. The operation status distribution server device 30 transmits the operation status data when the operation status is updated and when requested by another device.

  The server device 20 communicates with the operation status distribution server device 30 via the network 2. As shown in FIG. 5, the server device 20 includes an operation status data acquisition unit 400d. The operation status data acquisition unit 400d is supplied with data indicating the specified use route from the use route / transfer station specifying unit 354. When this data is supplied, the operation status data acquisition unit 400d transmits request data for requesting operation status data of the usage route indicated by the data to the operation status distribution server device 30 via the communication unit 310. When receiving the request data, the operation status distribution server device 30 transmits the latest operation status data at the time of reception to the server device 20. The operation status data is supplied to the operation status data acquisition unit 400d via the communication unit 310. Thus, the operation status data acquisition unit 400d functions as an operation status data acquisition unit that acquires the operation status data. The operation status data acquisition unit 400d supplies the acquired operation status data to the communication unit 310 in association with the departure time data and arrival time data supplied to the communication unit 310 by the boarding / transfer station departure time specifying unit 362. .

The communication unit 310 transmits the departure time data, arrival time data, and operation status data to the mobile terminal 10 together. In this way, when the operation status data acquisition unit 400d acquires the operation status data of the train that departs at the departure time extracted by the time extraction unit 360, the communication unit 310 transmits the operation status data together with the departure time data. Functions as a transmission means.
FIG. 25 is a diagram illustrating an example of an image displayed by the mobile terminal 10 in the present embodiment. In this example, routes A, C, and D are operated as usual, and route B is transmitted to the mobile terminal 10 indicating operation status data indicating that there is a 15-minute delay in the departure time. To do. The image shown in FIG. 25 is different from the image shown in FIG. 19 in the image displayed at the position of the image G9. In FIG. 25, an image G11 of a character string “operating as usual” is displayed next to “Route A”, and an image G12 of a character string “delayed by 15 minutes” is displayed next to “Route B”. Yes. Thereby, the user can know the operation status in the route in which the departure time is notified.

[Modification]
Each embodiment mentioned above is only an example of implementation of the present invention, and may be changed as follows. Moreover, you may implement combining each embodiment mentioned above and each modification shown below as needed.

(Modification 1)
In each embodiment described above, the case of notifying the departure time of the train has been described as an example, but the departure time notification system may notify the departure time of another vehicle. In this case, “departure”, “ride”, “get off”, and “station” in each part shown in FIG. It can be expressed as In addition, the departure time notification system may notify the departure time of each vehicle on a route that travels using a plurality of types of vehicles such as trains, buses, and airplanes. In any case, the traffic network storage unit 223 stores data indicating information about each boarding location, similar to the station data described above, and the timetable storage unit 225 stores the departure time of each vehicle at each boarding location. Need only be stored.

(Modification 2)
In each embodiment described above, the positioning device of the mobile terminal measures the position of the mobile terminal 10 using GPS technology. However, the positioning device is not limited to this, and the position may be measured using other technologies. For example, the positioning device may use a technique for measuring a position using communication with a base station, as disclosed in JP-A-2006-80681. In addition, the positioning device is a technology called A-GPS (Assisted Global Positioning System) that combines GPS and position measurement by communication with a base station, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2011-223501. May be used. In short, the positioning device may measure the position using any technique as long as it can measure the position of the mobile terminal.

(Modification 3)
The movement stillness determination unit 102 of the mobile terminal 10 may determine whether or not the mobile terminal 10 is moving by a method different from the embodiment described above. For example, the number of times that the measurement data generation unit 101 performs measurement in one set is set to three or more instead of two, and the moving stationary determination unit 102 selects each of two sets of measurement data having consecutive measurement times. Using the distance between the positions indicated by the set of measurement data, the above-described movement and stationary determination are performed. Then, the moving stillness determination unit 102 determines that the mobile terminal 10 is moving if the determined result (for example, a majority) of the determination results is moving. In the position measurement using the GPS technology, even if the position is measured twice during movement, it may happen that the position measured twice does not change (or hardly changes) due to the influence of the positioning error. In this case, it is determined to be stationary despite the movement. On the other hand, by setting the number of times of position measurement to 3 times or more, the position is always unchanged during movement even if there is an influence of positioning error, compared to the case of measuring only twice. Is less likely to occur.

  On the other hand, although the mobile terminal 10 is stationary, it may be determined that the position measured due to the influence of the positioning error has changed and moved. For example, the moving stationary determination unit 102 determines that the mobile terminal 10 is moving when a value obtained by subtracting the total positioning error from the distance between the positions measured twice is equal to or greater than a threshold value. May be. As a result, as described above, it is less likely that the mobile terminal 10 is determined to be moving when it is stationary.

  Increasing the number of times the position is measured as described above also increases the power consumed by the mobile terminal 10. In addition, when the distance between the measured positions is equal to or greater than the threshold value, but is less than the threshold value as a result of subtracting the total positioning error (this is referred to as “when the influence of the positioning error is large”), actually. There is also a possibility that the mobile terminal 10 is moving. Therefore, the moving stationary determination unit 102 normally performs determination using position information measured twice, and when the influence of the positioning error is large, the measurement data generation unit 101 is requested to perform the third measurement. The determination may be made using the position information measured for the third time and the third time. Note that the moving stillness determination unit 102 may request the number of measurements to be two or more, and may request further measurement if the influence of the positioning error is large even if the third measurement result is used. Good. Thereby, it is possible to determine whether or not the mobile terminal 10 is moving even when the influence of the positioning error is large while suppressing the power consumed by the mobile terminal 10.

(Modification 4)
The acquisition unit of the server device may acquire the terminal position and the measurement time by a method different from the above-described embodiments. For example, when the measurement data transmitted from the mobile terminal 10 does not include the measurement time, the acquisition unit acquires the current time when the measurement data is supplied from the communication unit 310 as the measurement time. To do. When the mobile terminal does not include the positioning device 160, the acquisition unit, for example, transmits data indicating the communication state between the mobile terminal and the base station from the mobile terminal or the base station. . The acquisition unit acquires the position of the mobile terminal calculated from the communication state indicated by the data and the position of the base station that performs the communication. In other words, this is a method of measuring the position using the above-described communication with the base station not on the mobile terminal side but on the server device side. In short, the acquisition unit only needs to function as an acquisition unit that acquires the terminal position, which is the position of the mobile terminal 10 possessed by the user, and the measurement time at which the terminal position is measured.

(Modification 5)
The route extraction unit of the server device may extract the route by a method different from the method in each of the embodiments described above (this is referred to as “first extraction method”). For example, the route extraction unit is not the distance between the square area indicating the position information included in the estimated route as in the first extraction method and the past route, but the total distance between the terminal position included in the estimated route and the past route. May be determined to be equal to or less than the threshold TH _d (this is referred to as “second extraction method”). In addition, the route extraction unit may determine the same route when the sum of the distances between the past route and the portion farthest from the past route in the square area described above is equal to or less than the threshold TH _d (this This is referred to as “third extraction method”). In the first extraction method, the sum of the distance between the square area and the past route represents the distance between the estimated route and the past route. In the second extraction method, the sum of the distance between the terminal position and the past route is: In the third extraction method, the sum of the distances between the past route and the farthest part of the square area and the past route represents the distance between the estimated route and the past route, respectively.

  In the first extraction method, the route is extracted on the assumption that the influence of the positioning error appears most in the direction away from the past route. In other words, the positioning error is used so that the distance from the past route is minimized. In the second extraction method, since the distance to the past route is larger than that in the first extraction method, it is difficult to determine the same route. In the third extraction method, it is more difficult to determine the same route compared to the second extraction method. In other words, in the order of the first, second, and third extraction methods, the criteria for determining the same route are becoming stricter.

For example, if the distance along the route from the start point to the end point of the route (referred to as “route distance”) is short, the number of position information is small, so even if the route is actually different, the total distance to the past route is in some cases it becomes smaller than the threshold TH _d. On the other hand, if the long path distance, due to the large number of location information, actually be the same route, there is a case where the sum of the distance between the last path becomes equal to or higher than the threshold TH _d. For example, if the distance l ₁₁ <l ₁₂ <l ₁₃ and the path distance is 0 or more and less than l ₁₁ , the route extraction unit determines the same route by the third extraction method, and the route distance is l ₁₁ or more and l _12. If the path distance is less than or equal to l _{12 and} less than l ₁₃ , the same route is determined by the first extraction method. Thereby, the route extraction unit can reduce the determination of different routes as the same route when the route distance is short, and can reduce the determination of the same route as a different route when the route distance is long.

(Modification 6)
In each embodiment and each modification described above, the route extraction unit of the server device extracts the same route based on the distance between the estimated route and the past route (this is referred to as “distance extraction method”). The same route may be extracted by this method. For example, the route extraction unit calculates, as the degree of coincidence, the ratio of the area of the estimated route that overlaps the past route to the total area, and the calculated degree of coincidence is greater than or equal to a threshold (for example, 0.9) In addition, the past route may be extracted as the same route as the estimated route (this is referred to as a “ratio extraction method”). Here, the degree of coincidence is the degree to which the estimated route matches the past route.

  When a user who is going to move along a certain past route starts to depart after starting to move, in the distance extraction method, if the distance from the past route increased by the detour exceeds the threshold, in that case The estimated route will not be extracted as the same route thereafter. Even in such a case, if the ratio extraction method is used, even if this past route is no longer extracted as the same route, the degree of coincidence increases when the detour or the like ends and becomes equal to or more than the threshold value. It can be extracted as a route.

  As described above, the route extraction unit may extract a past route whose degree of separation from the estimated route (specifically, the total distance) is less than a threshold value as the same route as in the distance extraction method. As in the ratio extraction method, past paths whose degree of coincidence with the estimated path (specifically, the ratio of overlapping areas) is equal to or greater than a threshold may be extracted as the same path. Here, if the sign (plus) of the degree of separation from the estimated route is reversed (minus), the degree of agreement with the estimated route can be obtained. For example, the route extraction unit may extract a past route having a degree of coincidence equal to or greater than a threshold (eg, 0 m) using a value obtained by subtracting the total distance from the estimated route from a predetermined distance (eg, 200 m) as the degree of coincidence. Good. In this case, the past route is not extracted when the total distance from the estimated route exceeds 200 m. That is, extraction similar to that in the above-described embodiment is performed. As described above, the route extraction unit may be any device that functions as a route extraction unit that extracts a past route whose degree of coincidence with an estimated route is equal to or greater than a threshold value.

(Modification 7)
In the above-described embodiment, when there are a plurality of identical routes extracted by the route extraction unit 330, the specifying unit 350 has the same route that the mobile terminal 10 has passed through the same route, that is, one identical route. Although a station whose station position is included in the route is specified, a station whose station position is included in a plurality of identical routes may be specified. For example, the specifying unit 350 specifies a station whose station position is included in the same route up to the order determined from the number of times that the mobile terminal 10 has passed the most among a plurality of the same routes. The specifying unit 350 uses the number of passages stored in association with the same route by the use route storage unit 224 as the number of times of passage here.

  In this case, the time extraction unit 360 extracts departure times on the plurality of identified same routes, and departure time data indicating the departure times is transmitted to the mobile terminal 10. For example, the mobile terminal 10 may display the departure times on the same route as indicated by the departure time data side by side on one screen, or display the departure times on one same route for each screen. The screen may be switched by an operation such as dragging. According to this modification, it is possible to notify the user of departure times on a plurality of the same route that the user may move, and further, the user may move on the same route. It can be relatively high.

(Modification 8)
The specifying unit 350 may consider a time zone when specifying a station according to the number of times the mobile terminal 10 has passed. Specifically, the specifying unit 350 includes a time zone including the time when the terminal position included in the estimated route is measured (hereinafter referred to as “current time zone”) and a time zone in which the mobile terminal 10 passes the same route ( (Hereinafter referred to as “past time zone”), for example, the number of passages of the same route is compared after weighting such that the passage is counted as two times. In this case, the use route storage unit 224 stores each route, the time zone in which the mobile terminal 10 has passed the route, and the number of times the mobile terminal 10 has passed the route in the time zone in association with each other. .

  FIG. 26 is a table showing an example of information stored in the use route storage unit 224. In this table, in addition to what is shown in FIG. 12, “time zone” is shown. In the “time zone”, three time zones “4 o'clock to 10 o'clock”, “10 o'clock to 17 o'clock”, and “17:00 to 4 o'clock” are shown. Each route ID “Z1”, “Z2”, and “Z3” is associated with the “number of passes” for each time zone. For example, “Z1” has “5” as the number of passages from “4 to 10:00”, “0” as the number of passages from “10:00 to 17:00”, and “5” as the number of passages from “17:00 to 4”. " “Z2” has “6” as the number of passages from “10:00 to 17:00”, and “0” as the number of passages in other time zones. In addition, “Z3” has “0” as the number of passages from “4 to 10:00” and “1” as the number of passages in other time zones.

  When the routes Z1, Z2, and Z3 are extracted as the same route and the current time zone is “10:00 to 17:00”, the specifying unit 350 passes these routes associated with this time zone. After the number of times is doubled, the number of passes in each time zone is totaled. As a result, the total number of passes through the paths Z1, Z2, and Z3 is “10”, “12”, and “3”, respectively. The specifying unit 350 specifies a station included in the route Z2 that is the same route having the largest total number of times of weighting as described above. Note that the specifying unit 350 may specify a station whose station position is included in a plurality of identical routes, as in the above-described modification. Further, the specifying unit 350 may not only increase the number of times of passage in the current time zone but also weight the number of times of passage in time zones other than the current time zone. For example, if the number of passes in a time zone other than the current time zone is multiplied by 0, only the number of passes in the same time zone as the current time zone is compared. In short, the specifying unit 350 weights the number of passes stored in the use route storage unit 224 in association with the time zone including the measurement time used in the extraction of a plurality of the same routes by the route extraction unit 330, It only needs to be able to identify the station.

  The route Z1 shown in FIG. 26 is often used during commuting or returning home, but is not likely to be used during daytime. On the other hand, although the route Z2 is often used during the daytime, it is highly likely that the route Z2 is not used during the time of commuting or returning home. If the current time zone is the daytime zone, there is a high possibility that the route along which the user moves is the route Z2. According to this modification, it is possible to identify a station included in a route having a high possibility of being used in the time zone from among routes having a possibility of being used depending on the time zone.

(Modification 9)
When using the route search algorithm, the use route / transfer station specifying unit 354 may add a condition that, for example, the express train is not used when the distance between the start point and the end point of the route is smaller than the threshold. In addition, the used route / transfer station specifying unit 354 detects routes having different merits, such as a route having the shortest distance traveled or a route having the least number of transfers by adjusting the cost between stations. May be. In addition, the use route / transfer station specifying unit 354 may detect a predetermined number of routes in order from the lowest total cost as well as the lowest total cost.

(Modification 10)
In each embodiment described above, the boarding station / transfer station departure time specifying unit 362 specifies the departure time at the boarding station in the case of departure from the current time from the boarding station to the getting-off station. You may specify the departure time of the train which a user gets on, when moving along the same route which the route extraction part 330 extracted after the acquired measurement time. Between the time when the measurement data generation unit 101 measures the terminal position and the time when the boarding station / transfer station departure time specifying unit 362 performs the operation of specifying the departure time, the operation of each unit shown in FIG. 10 and the server device 20 are communicating. For this reason, the measurement time, that is, the time when the terminal position is measured is different from the time when the departure station / transfer station departure time specifying unit 362 specifies the departure time (referred to as “specific time”). .

  For example, when the user activates the notification processing program and the terminal position is measured, the user is in front of the station, but when the boarding station / transfer station departure time specifying unit 362 specifies the departure time, the user has already boarded the train. It can happen. In such a case, even if the departure time after the specific time is specified, the departure time of the train on which the user actually got on is not notified. According to this modification, even when the user moves from the measurement time to the specific time, the time before the movement, that is, the departure time after the measurement time is notified, so the user can get on The train departure time can be notified. Note that when the departure station / transfer station departure time specifying unit 362 specifies the modified example while the mobile terminal 10 is stationary, the departure times of vehicles that have already started may be extracted. Therefore, when the mobile terminal 10 is stationary, that is, when no measurement data is transmitted from the mobile terminal 10, the boarding station / transfer station departure time specifying unit 362 displays the current time as in each embodiment. The departure time may be specified using.

(Modification 11)
In each embodiment described above, the transfer station / transfer station departure time specifying unit 362 specifies the departure time of the transfer station, the arrival time of the transfer station, the departure time of the transfer station, and the arrival time of the departure station. However, one or two of each may be specified, or four or more may be specified. For example, the transfer station / transfer station departure time specifying unit 362 specifies the departure time of the transfer station and the arrival time of the transfer station three by three, and specifies the departure time of the transfer station and the arrival time of the disembarkation station by five each. . An image displayed by the mobile terminal 10 when this specification is performed will be described with reference to FIG.

  FIG. 27 is a diagram illustrating an example of an image displayed by the mobile terminal 10 in the present modification. In the example shown in FIG. 19, an arrow extending from the character string “9:05” toward the character string “9:16” is displayed as the image G9. For example, the user points this arrow to the right. By dragging, an image G13 which is an arrow extending from the character string “9:10” toward the character string “9:21” is displayed. This represents notification of the time when the user gets on a train that leaves the A1 station at 9:10. In this case, the arrival time of the A3 station is 9:21, and the character strings “9:24”, “9:29”, and “9:34” that are the departure times of the trains that depart from the B3 station at the following time. The image G14 is displayed.

  Also, an image G15 is displayed that represents the character strings “3 minutes”, “8 minutes”, and “13 minutes” that are the time required for each transfer, and the arrows superimposed on those character strings. Image G15 represents the transfer time when the transfer indicated by the arrow is performed at the transfer station (A3B1 station), similarly to image G8 shown in FIG. Further, an image G16 representing the arrival time at the B3 station and an image G17 representing the required time when moving as indicated by the arrows are displayed. When the arrow of the image G13 is dragged to the left side to display an image of an arrow extending from the character string “9:00” toward the character string “9:16”, the mobile terminal 10 Displays the departure times of three different destination trains when the train departs A1 station at 9:00. According to this modification, the user can check the departure time of a train that can be changed even when the train on the boarding station is changed.

(Modification 12)
The departure station / transfer station departure time specifying unit 362 does not specify the departure time at the boarding station when the departure station departs from the departure station at a certain time, but determines all departure times at the departure station. You may specify. In this case, in the mobile terminal 10, when the user moves along the route extracted by the route extraction unit 330, all the trains to be boarded at the boarding station and the transfer station specified by the specifying unit 350 are displayed. Departure time data indicating the departure time is transmitted. For example, the mobile terminal 10 drags the images G4 and G6 shown in FIG. 19, that is, the departure time at the A1 station that is the boarding station and the departure time at the A3B1 station that is the transfer station, to the left and right, respectively. The departure time until the last train is displayed.

  In short, the time extraction unit 360 has moved along the route extracted by the route extraction unit 330 from a plurality of departure times stored in the timetable storage unit 225 in association with the station specified by the specification unit 350. In this case, it is only necessary to extract the departure time of the train on which the user gets. The departure / departure station departure time specifying unit 362 may perform the same specification for the arrival time. In that case, the mobile terminal 10 displays the transfer time and the required time as in the example shown in FIG. Even when the departure time notification system of this modification is used, if the user activates the notification processing program, the user does not need to perform an operation of inputting a character string representing the boarding station or the getting-off station. It is possible to know information such as departure time, transfer time, and required time at the boarding station.

(Modification 13)
In the departure time notification system 1, the departure time of the train on which the user gets on when moving along the route extracted by the route extraction unit 330 and the arrival time of the train on which the user gets off in the same case are given to the user. Although notified, only the departure time may be notified. In that case, for example, when the specifying unit 350 moves along the above route, the user may specify only the station on which the user gets on the train and may not specify the station to get off, or the time extracting unit 360 may Only the departure time of the train on which the user gets on may be extracted, and the arrival time of the train on which the user gets off may not be extracted. Further, the communication unit 310 may transmit only the departure time data described above and may not transmit the arrival time data. In either case, the mobile terminal 10 displays the departure time of the train on which the user is likely to get on. Therefore, the user can move in time for the departure time, or set the time until the departure time. It can be used effectively.

(Modification 14)
In addition to the server device, the mobile terminal, and the departure time notification system, the present invention can also be understood as a method for realizing the processing performed by them. The processing here is, for example, the processing shown in FIG. 14 performed by the mobile terminal or the processing shown in FIG. 14 to FIG. 18 and FIG. 20 performed by the server device. Further, the present invention can also be understood as a program for causing a computer including a storage device such as a server device to function as each unit shown in FIG. Such a program may be provided in the form of a recording medium such as an optical disk storing the program, or may be provided in a form such that the program is downloaded to a computer via a network such as the Internet, and the program can be installed and used. You may do.
