Abstract

PROBLEM TO BE SOLVED: To provide a server for specifying transportation to be used by a user while reducing power consumption on a communication terminal side.SOLUTION: Two or more pieces of positional information acquired from a mobile terminal 10 carried by a user are acquired in the transportation facility specifying server 20. A moving route is estimated from the positional information of the mobile terminal 10. A station used by the user of the mobile terminal 10 is specified on the basis of the estimation result and information indicating the position of the station (point) of the transportation stored in a traffic network information storage part 27. The transportation used by the user of the mobile terminal 10 is specified on the basis of the information of the station.

Information is distributed to communication terminals.

JP 2011-148415 A

  However, the system described in Patent Document 1 has the following problems. That is, in the system described in Patent Document 1, the communication terminal acquires position information, for example, every second, and compares the position information with the route of public transportation to identify the transportation facility used by the user. Although it is shown, if the position information is acquired with high frequency in this way, the power consumption of the communication terminal increases. For this reason, there is a possibility that it is difficult to continuously use the system described in Patent Document 1, for example, only for navigation during sightseeing.

  The present invention has been made in view of the above, and a used transportation facility identification server, a transportation facility identification system, and a transportation facility identification system that can identify a transportation facility used by a user while suppressing power consumption on the communication terminal side. The purpose is to provide a method for identifying the transportation system used.

  In order to achieve the above-mentioned object, the use transportation facility specifying server according to the present invention is a use transportation facility specifying server that specifies a use transportation facility used by a user of a mobile terminal, and is a traffic that the user may use. Traffic network information holding means for holding traffic network information including information indicating the position of a use point for using an institution, and position information acquisition means for acquiring a plurality of position information related to the terminal from the mobile terminal; , A movement route estimation means for estimating a movement route of the mobile terminal from the plurality of position information acquired by the position information acquisition means, a movement route of the mobile terminal estimated by the movement route estimation means, and the traffic Usage point identification that identifies the usage point used by the user of the mobile terminal based on information indicating the location of the usage point included in network information And, based on the use points used by the user of the mobile terminal specified by the use point specifying means and the transport network information, use transport means specifying means for specifying the use transport means of the mobile terminal, It is characterized by providing.

  In addition, the method of identifying a used transportation facility according to the present invention holds transportation network information including information indicating the position of a use point for starting or ending the use of a transportation that a user of a mobile terminal may use. A transportation network identifying method for retaining a transportation network information holding means for identifying a transportation facility used by the user, and for identifying a transportation facility used by the transportation facility identification server. From the position information acquisition step, the position information acquisition step to estimate the movement route of the mobile terminal from the position information acquisition step, and the movement route estimation step Based on the movement route of the mobile terminal and the information indicating the position of the use point included in the traffic network information, the user of the mobile terminal Based on the use point specifying step for specifying the used point used, the plurality of position information acquired in the position information acquisition step, and information indicating the position of the use point included in the traffic network information, Based on the use point specifying step for specifying the use point used by the user of the mobile terminal, the use point used by the user of the mobile terminal specified in the use point specifying step, and the traffic network information, And a used transportation mode specifying step for specifying a used transportation system of the mobile terminal.

  According to the above-mentioned use transportation facility specifying server and use transportation facility specification method, the travel route of the mobile terminal is estimated based on a plurality of pieces of position information acquired from the mobile terminal and information indicating the position of the use point of the transport facility. In addition, after identifying the use point used by the mobile terminal from the travel route, the use transportation system used by the user of the mobile terminal is specified based on the information of the use point. In this way, only the transportation use point is specified from the location information of the mobile terminal, and the use transportation used by the user of the mobile terminal is specified based on the use point. Compared with the case where the transportation system used by the user is identified by comparing with the route map, the transportation system used can be identified from less information. Accordingly, it is possible to reduce the number of times of acquisition of the location information for specifying the used transportation facility in the mobile terminal, and it is possible to reduce the information transmitted to the used transportation facility specifying server. It is possible to specify the transportation facility used by the user while suppressing power consumption on the communication terminal side. In addition, the information used in the used transportation facility specifying server can be reduced, and the processing efficiency can be improved.

A usage point within a range may be specified as the usage start point, and a usage point within a range of the usable distance from an end point of movement by a mobile terminal may be specified as the usage end point.

  By using the above aspect, even when there are a plurality of transportation facilities or usage points that the user may use, the usage points within the usable distance range are used as the usage start points or usage end points. By applying to the specification of the use transportation system, it is possible to prevent the user from specifying the use transportation system incorrectly.

  In addition, when the specified use start point includes a plurality of use points included in the same route, the use transportation means specifying means removes the use points other than the closest use point from the use start point and specifies When the usage end point includes a plurality of usage points included in the same route, a mode other than the usage point closest to the end point can be removed from the usage end point.

  By using the above aspect, it is possible to avoid the use points included in the same route from being included in the use start point and the use end point, so it is possible to specify the use transportation facility with higher accuracy. It becomes.

<Configuration of used transportation system identification system>
FIG. 1 is a schematic configuration diagram illustrating a configuration of a use transportation facility specifying system according to the present embodiment. As shown in FIG. 1, the use transportation facility specifying system 1 includes a mobile terminal 10 and a use transportation facility specifying server 20. Information is transmitted and received between the mobile terminal 10 and the use transportation facility specifying server 20 by wireless communication via the mobile communication network. This use transportation system specifying system 1 provides, for example, a server that provides traffic information (for example, delay information) related to public transportation, and regional information (for example, store information) according to the position of the mobile terminal 10. This is applied to servers that And the function which the information according to the position of the mobile terminal 10 is provided by the use transportation system specific server 20 by transmitting the information which shows the position of the own machine from the mobile terminal 10 to the use transportation system identification server 20 is provided. Have.

  Public transportation systems to which the use transportation system specifying system 1 according to the present embodiment can be applied include trains, expressways, airplanes, and the like. In the use transportation system specifying system 1 described below, a user uses a train. Will be described. When the user uses a train, the user performs getting on, getting off, and changing at the “station”, and thus corresponds to a point for the station to use the train, that is, a use point. In the use transportation facility specifying server 20 according to the present embodiment, it is determined from the location information through which station (use point) the user has used the transportation facility, and after identifying the station through which the user has passed, It is characterized by specifying the transportation facility used by the user.

  The mobile terminal 10 included in the use transportation system specifying system 1 is used by a user, and specifically, realized as a device having a communication function such as a mobile phone and a PDA (Personal Digital Assistance). Further, the mobile terminal 10 according to the present embodiment has a function of acquiring position information of the own device. As a method of acquiring position information, for example, by receiving signals from three or more GP (Global Positioning System) satellites in the sky, the position of the receiving terminal (mobile terminal 10) (based on the position information of the GPS satellites ( Specifically, GPS positioning is used to determine latitude, longitude, and altitude. Further, the used transportation facility specifying server 20 included in the used transportation facility specifying system 1 is used by an information provider who provides information to the mobile terminal 10.

  As illustrated in FIG. 2, the mobile terminal 10 includes hardware such as a CPU (Central Processing Unit) 101, a RAM 102, a ROM 103, an operation unit 104, a wireless communication unit 105, a display 106, and an antenna 107. The functions of the mobile terminal 10 are exhibited by the operation of these components. Further, as shown in FIG. 3, the use transportation facility specifying server 20 includes a CPU 201, a RAM (Random Access Memory) 202 and a ROM (Read Only Memory) 203 which are main storage devices, a communication module 204 for performing communication, and a hard disk. It is comprised as a computer provided with hardware, such as auxiliary storage devices 205. And the function of each apparatus is exhibited when these components operate.

  Returning to FIG. 1, the mobile terminal 10 and the used transportation facility specifying server 20 included in the used transportation facility specifying system 1 will be described in detail.

  The mobile terminal 10 includes a positioning unit 11 (positioning unit), a moving stillness determination unit 12, a communication unit 13 (position information transmission unit), and a display unit 14.

  The positioning unit 11 has a function of acquiring position information (latitude, longitude, altitude, etc.) for specifying the position of the mobile terminal 10 based on the operation of the mobile terminal 10 by the user. The position information acquisition method by the positioning unit 11 may be the above-described GPS positioning, for example, a cell that uses information specifying the position of the area where the mobile terminal 10 is located as the position information of the mobile terminal 10. Positioning or the like may be used. Acquisition of the position information of the mobile terminal 10 by the positioning unit 10 is continuously performed a plurality of times. For example, the acquisition of the continuous position information may be performed periodically at a predetermined interval (for example, every 5 minutes) in the mobile terminal 10. The position information acquired by the positioning unit 11 is sent to the moving stillness determination unit 12.

  The moving stillness determination unit 12 has a function of determining whether or not the mobile terminal 10 is moving based on the position information acquired by the positioning unit 11. The determination as to whether or not the mobile terminal 10 is moving is made when the distance between two consecutive pieces of position information among the position information acquired by the positioning unit 11 is smaller than a predetermined threshold (predetermined value). Is determined to be stationary, and if it is larger, it is determined to be moving. In addition, when the position information includes a considerable positioning error, a method of determining whether the moving or stationary state is obtained by subtracting the positioning error from the distance between the positions of two consecutive points and then comparing with a threshold value. It may be used. In the mobile terminal 10, since only the position information of the time zone determined to be moving by the moving stationary determination unit 12 among the position information acquired by the positioning unit 11 is transmitted to the use transportation facility specifying server 20. Information is sent to the communication unit 13. In addition, when the moving and stationary determination unit 12 determines that the vehicle is stationary, the position information is not transmitted to the use transportation facility specifying server 20. Thereby, the transmission / reception amount of the positional information between the mobile terminal 10 and the use transportation system identification server 20 can be reduced.

  The communication unit 13 has a function of transmitting / receiving information to / from the use transportation facility specifying server 20. Specifically, the position information of the time zone determined to be moving by the moving stationary determination unit 12 is transmitted to the use transportation facility specifying server 20 and transmitted from the use transportation facility specifying server 20 based on the position information. Has a function of receiving received content. The content transmitted from the use transportation facility specifying server 20 is transmitted from the communication unit 13 to the display unit 14.

  The display unit 14 has a function of displaying the content transmitted from the use transportation facility specifying server 20. When the display unit 14 displays the content, the user of the mobile terminal 10 can check the content.

  Next, the use transportation facility specifying server 20 will be described. The use transportation facility specifying server 20 includes a communication unit 21 (position information acquisition unit), a position information storage unit 22, a movement route estimation unit 23 (movement route estimation unit), a spatially identical route determination unit 24 (movement route update unit), Travel route update unit 25 (travel route update unit), travel route storage unit 26 (travel route holding unit), traffic network storage unit 27 (traffic network information holding unit), spatial overlap station specifying unit 28 (use point specifying unit) , Boarding / departure station specifying unit 29 (use transportation means specifying means), traffic route specifying unit 30 (use transportation means specifying means), use route storage section 31, transfer point specifying section 32 (use transportation means specifying means), contents storage section 33 and a content distribution unit 34.

  The communication unit 21 has a function of transmitting / receiving information to / from the mobile terminal 10. Specifically, the mobile terminal 10 has a function of receiving position information transmitted from the mobile terminal 10 and transmitting content based on the position information from the mobile terminal 10 to the mobile terminal 10. The location information from the mobile terminal 10 received by the communication unit 21 is sent to the location information storage unit 22.

  The location information storage unit 22 has a function of storing location information transmitted from the mobile terminal 10. Information stored in the position information storage unit 22 is used by a movement route estimation unit 23, a spatially identical route determination unit 24, and a movement route update unit 25, which will be described later.

  The movement route estimation unit 23 has a function of estimating the movement route of the mobile terminal 10 based on the position information. As a method of estimating the movement route, for example, there are the following methods. Based on the position information from the mobile terminal 10, the movement route estimation unit 23 detects an area where the mobile terminal exists at every predetermined period, and assigns an area ID for identifying the area as shown in FIG. And accumulate. Here, the area where the mobile terminal exists is a circular area specified by latitude, longitude, and measurement error, but in order to simplify the process in the spatial same path determination unit described later, a rectangular area including the circular area May be expressed as Then, based on which area the mobile terminal 10 has moved in a series of moving actions of the mobile terminal 10 (referred to as movement during which it is continuously determined as “moving” from the position information). Estimate the travel route. For example, when the mobile terminal 10 moves along the route R1 shown in FIG. 5, it is assumed that the areas where the mobile terminal 10 is determined to exist based on the location information are E001, E003, and E005 in chronological order. . In this case, the movement route estimation unit determines that the route of E001 → E003 → E005 has been followed. Information related to the movement route estimated by the movement route estimation unit 23 is sent to the spatially identical route determination unit 24.

  The spatially identical route determination unit 24 has a function of determining whether or not the travel route estimated by the travel route estimation unit 23 is the same as the route traveled by the mobile terminal 10 in the past. This is determined based on whether or not the travel route specified from the information stored in the travel route storage unit 26 matches the travel route estimated by the travel route estimation unit 23. Judgment of whether the movement route specified from the information stored in the movement route storage unit 26 matches the movement route estimated by the movement route estimation unit 23 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2010-160797. It can be realized by the described technique. The result determined by the spatially identical route determination unit 24 is sent to the movement route update unit 25.

  In the movement route update unit 25, information related to the movement route stored in the movement route storage unit 26 is updated based on the determination result by the spatially same route determination unit 24.

  An example of information related to the travel route stored in the travel route storage unit 26 is shown in FIG. As shown in FIG. 6, the movement route storage unit 26 stores the movement route indicated by the departure area, the transit area, and the arrival area, and the number of movements (the number of times of use) of the movement route. When the spatial route determination unit 24 determines that the travel route of the mobile terminal 10 is the same as the past travel route, that is, when the travel route is already stored in the travel route storage unit 26. Then, the movement route update unit 26 adds 1 to the number of movements of the movement route. On the other hand, if the spatially identical route determination unit 24 determines that the movement route of the mobile terminal 10 is a new route, the movement route update unit 26 stores the new movement route in the movement route storage unit 26. The In this way, information related to the travel route of the mobile terminal 10 is stored in the travel route storage unit 26. Using the information related to the travel route of the mobile terminal 10 stored in the travel route storage unit 26, the transportation system used by the mobile terminal 10 to be described later is specified. By updating the movement route, more accurate information can be provided using the information.

  The traffic network storage unit 27 has a function of storing traffic network information including information indicating the position of a usage point for starting or ending the use of a transportation that a user may use. In the present embodiment, since movement by train is assumed, as information related to a “station” that is a use point for starting or ending use of a train, information specifying a route to enter the station, Information for specifying an adjacent station and information for specifying the position of the station are stored. Specifically, as shown in FIG. 7, route ID (information identifying a route), route name, station ID (information identifying a station), station name, route order (order of stations on the route), adjacent station ( A station ID that identifies an adjacent station), a station group ID (used when there is a transferable station), a latitude, and a longitude are stored in association with each other.

  Here, an outline of a method for specifying the use transportation facility in the use transportation facility specifying server 20 according to the present embodiment will be described with reference to FIG. FIG. 8 is a diagram for explaining an example of a method for identifying a used transportation facility. Here, it is assumed that the use transportation facility specifying server 20 grasps that the mobile terminal 10 stays in the areas of E001, E003, and E005 as a precondition for identifying the use transportation facility. On the other hand, the transportation network storage unit 27 of the use transportation facility specifying server 20 stores information related to A01 to A12 (information indicating the position of the central station of the rectangular area and the size of the rectangular area) as information relating to the station. Suppose you were. In addition, a rectangular area created by the continuous areas E001 and E003 in the area where the mobile terminal 10 stays is E101, and a rectangular area created by the areas E003 and E005 is E102. This E101 is a movement route that is estimated to have passed when the user (mobile terminal 10) has moved from the area E001 to E003. Similarly, E102 is a movement route that is estimated to have passed when the user (mobile terminal 10) has moved from area E003 to E005.

  Here, by using the use transportation facility specifying server 20 to specify that the area E101 estimated as the travel route of the user (mobile terminal 10) and the station areas A01, A02, A03, A07 and A10 overlap, the user can It is estimated that A01, station A02, station A03, station A07 or station A10 was used. From this, the user may have used any of the routes A to C. In addition, by specifying that the area E102 and the station areas A04, A05, A08, and A09 overlap in the use transportation facility specifying server 20, the user specifies that the station A04, the station A05, the station A08, or the station A09 has been used. Is done. Here, since the station A06 is not included in the area E102 estimated to be the user's travel route, it is considered that the user may have used the route A or the route B instead of the route C.

  Further, as shown in FIG. 8, since the station A03 is also a transfer station between the route A and the route B, there is a possibility that the user has changed from the route A to the route B at the station. In addition, since the station A09 on the route A and the station A08 on the route B are both included in the area E102, it is difficult to determine which of the route A and the route B is used only from the estimation of the moving route. is there. However, it is presumed that it is more common to use the route A from the station A01 to the station A05 as a route with a small number of transfers and a short route. Therefore, when the use transportation facility is specified, a route using the route A is derived by calculation using a route search algorithm.

  The used transportation facility identification server 20 according to the present embodiment identifies the transportation facility used by the user by the above process. That is, based on the area where the mobile terminal 10 stayed specified by the location information of the mobile terminal 10 is estimated, the movement route of the mobile terminal 10 is estimated (a rectangular area formed by two consecutive areas is derived) By verifying whether the travel route and the station area of each route of the transportation system overlap, the mobile terminal 10 estimates the station that the mobile terminal 10 seems to have traveled through, and determines the transportation system used from the information of the station. Identify. Further, as in the case of routes A and B in FIG. 8, when it is not possible to identify the transportation system used only by estimating the travel route, a route that is generally considered to be used by the user is derived using a route search algorithm, A method of identifying the user's transportation means for the transportation means of the route is used.

  Note that when the movement route of the mobile terminal 10 is determined to be the same as the past movement route by the spatially same route determination unit 24, that is, when the movement route is already stored in the movement route storage unit 26. When estimating the movement route of the mobile terminal 10 (rectangular area to be the movement route: when deriving the areas E101 and E102 in FIG. 8), when the mobile terminal 10 has moved on the same route in the past The position information that is stored in the movement route storage unit 26 can be used for the estimation of the movement route. Thereby, it is possible to estimate the movement route with higher accuracy.

  The above points will be described with reference to FIG. In the example shown in FIG. 9, as in FIG. 8, the use transportation facility specifying server indicates that the mobile terminal 10 stayed in the areas E001, E003, and E005 as a precondition for use transportation facility identification. Suppose that it was grasped at 20. Here, if the spatial route determination unit 24 determines that the travel route of the mobile terminal 10 is the same as the travel route used in the past, it is stored in the travel route storage unit 26. It is possible to use past position information. Here, it is assumed that information specifying the area E021 and the area E022 illustrated in FIG. 9 is stored in the movement route storage unit 26 as the position information related to the movement route of the mobile terminal 10. By combining the position information (E001, E003, E005) obtained during the movement of the mobile terminal 10 this time with the information of the areas E021 and area 022 stored in the movement path storage unit 26, FIG. A rectangular area different from the rectangular area shown is formed. Specifically, as shown in FIG. 9, a rectangular area E201 is formed from the area E001 and the area E021. Similarly, the area E021 and the area E003 form a rectangular area E202, the area E003 and the area E022 form a rectangular area E203, and the area E022 and the area E005 form a rectangular area E204.

  The rectangular areas E201 to 204 formed in this way are areas indicating a movement route estimated to have passed when the mobile terminal 10 moves, but are compared with the rectangular areas E101 and 102 shown in FIG. The area of the rectangular areas E201 to 204 is reduced. As a result, comparing FIG. 8 and FIG. 9, in FIG. 9, the station area A08 that identifies the station A08 included in the route B is a moving route (rectangular areas E201 to E201). 204). Therefore, since the station A08 included in the route B is not included in the estimation result of the travel route, the use transportation facility specifying server 20 can determine that the user has used the route A instead of the route B. In this way, it is determined whether the mobile terminal 10 is the same as the past travel route, and the used transportation facility is specified based on the result, thereby more accurately identifying the used transportation facility based on the travel route. It becomes possible. In this case, since the specific ratio of the used transportation facility using the route search algorithm is reduced, the accuracy of identifying the transportation facility used by the mobile terminal 10 is improved.

  Hereinafter, the function of each part which implement | achieves said process is demonstrated. The spatial overlap station specifying unit 28 compares the movement route of the mobile terminal 10 stored in the movement route storage unit 26 with the information specifying the station stored in the traffic network storage unit 27, and moves the mobile terminal 10. It has a function to identify stations that overlap with the route. Specifically, information for identifying a station that spatially overlaps an area included in the travel route of the mobile terminal 10 is extracted from the station stored in the traffic network storage unit 27. Here, since the information stored in the traffic network storage unit 27 is information indicating one point of the station derived from the latitude and longitude as shown in FIG. 7, for example, the point specified by the latitude and longitude of the station There is a method in which a square area having a side of 200 m on both sides of east and west and north and south is defined as a “station area”, and overlapping stations are extracted depending on whether or not an area overlapping with this station area is included in the travel route. Information on the stations determined to be duplicated by the spatially overlapping station specifying unit 28 is sent to the boarding / exiting station specifying unit 29.

  The boarding / exiting station specifying unit 29 has a function of specifying a station that is a candidate of “boarding station” or “getting off station” from the stations determined to be on the moving route by the spatially overlapping station specifying unit 28. When the mobile terminal 10 moves through a plurality of stations in a series of moving actions, there is a high possibility that the use of transportation is started at a station near the starting point of the moving route, and the use of transportation at a station near the end of the moving route is used. It's likely that it was finished. The boarding / exiting station specifying unit 29 extracts boarding station candidates and stations of the getting-off station candidates from the above viewpoint. As a specific method, the station closest to the starting point of the moving route is extracted as one of the candidates for the “boarding station”, and the distance d between the station and the starting point of the moving route is calculated. Thereafter, a distance d + α obtained by adding a predetermined distance α to the distance d is set as an available distance (a distance estimated to be usable as a boarding station), and a station having a distance from the starting point smaller than the available distance is “ Further extraction as “boarding station candidates”. Similarly, a plurality of candidates are also extracted for the getting-off station using the distance from the end point of the moving route. In addition, if multiple candidates extracted by this method include multiple stations on the same route, it is generally considered that there is a low possibility of getting on or getting off at a station other than the nearest station, so the starting point or the ending point It is preferable to exclude stations other than the nearest station. Information regarding the boarding / alighting station specified in this way is sent to the traffic route specifying unit 30.

The traffic route specifying unit 30 is based on the information on the station determined to be on the moving route by the spatially overlapping station specifying unit 28 and the boarding station candidate and the getting-off station candidate specified by the getting-on / off station specifying unit 29. Thus, it has a function of specifying a route that can be reached from the boarding station candidate to the getting-off station candidate. As a specific method, for a station determined to be on the travel route, an adjacent station ID and a station group ID are acquired from the traffic network storage unit 27 in correspondence with the station ID of the station, and Dijkstra, A ^*, etc. The traffic route is identified using the route search algorithm. Then, the boarding station, the getting-off station, the use route, and the use station that minimize the total cost are specified. Conditions can be appropriately added to the route search algorithm. As an additional condition in the route search, for example, when the distance between the start point and the end point of the moving route is smaller than a predetermined threshold, the user does not use the express vehicle.

  Note that, in the method for specifying the use transportation facility of the present embodiment, a plurality of use transportation facilities are prepared. When using the route search algorithm, it is possible to perform route search more in line with the user's behavior by setting the cost between stations as appropriate, for example, the cost between stations when transfer occurs By adjusting, it is also possible to extract a plurality of movement routes having different merits such as a shortest movement route and a movement route with few transfers. In addition to the above method, as a method of extracting a plurality of movement routes, a method of extracting N cases from the top in order of decreasing total cost, or a value obtained by adding a predetermined amount of cost from a movement route having the smallest total cost A method of extracting a movement route having a small total cost can also be used. Thereafter, the travel route identifying unit 30 identifies the travel route considered to be used by the mobile terminal 10 this time.

  The used transportation facility of the mobile terminal 10 specified by the traffic route specifying unit 30 is stored in the used route storage unit 31. Moreover, the transfer point specific | specification part 32 has a function which specifies a transfer station among the use routes (utilization transportation) specified by the traffic route specific | specification part 30. FIG. Specifically, a station having the same station group ID among the used transportation facilities stored in the used route storage unit 31 is specified as a transfer station. As a result, an example of information stored in the use route storage unit 31 is shown in FIG. In the use route storage unit 31, in correspondence with a user ID (information for specifying the mobile terminal 10), a travel route ID (information for specifying the travel route), information for specifying the boarding station (boarding route ID and station ID), Information for specifying the getting-off station (getting-off route ID and station ID), use route ID (information for specifying the used transportation facility), and information for specifying the transfer station are stored. Information relating to the station specified as the transfer station is also sent to the content distribution unit 34 and used for content distribution.

  The content storage unit 33 has a function of storing information relating to stations and transportation facilities stored in the traffic network storage unit 27. An example of information stored in the content storage unit 33 is shown in FIG. As illustrated in FIG. 11, the content storage unit 33 stores information to be distributed in association with a station ID or route ID, and a distribution time zone. These pieces of information are used when the content distribution unit 34 distributes content to the mobile terminal 10.

  The content distribution unit 34 has a function of acquiring content from the content storage unit 33 based on the information related to the travel route / transportation used specified / extracted by the traffic route specifying unit 32 and distributing the content to the mobile terminal 10. Have. Specifically, it relates to the user's use transportation system of the mobile terminal 10 specified by the traffic route specifying unit 30, the boarding station, the getting-off station, and the transfer point of the user of the mobile terminal 10 specified by the transfer point specifying unit 32. Information is extracted from information stored in the content storage unit 33. Then, by transmitting this from the communication unit 21 to the mobile terminal 10, the content is distributed to the mobile terminal 10.

<Used transportation system identification method by used transportation system identification system>
Next, a method for specifying the use transportation facility by the use transportation system specifying system 1 will be described with reference to the sequence diagram shown in FIG.

  First, position information is acquired in the positioning unit 11 of the mobile terminal 10 (S01). This can be performed in the mobile terminal 10 periodically at predetermined intervals. The position information acquired by the positioning unit 11 of the mobile terminal 10 is subjected to a moving still determination by the moving still determination unit 12 (S02). As a result, the position information determined to be moving is transmitted from the communication unit 13 of the mobile terminal 10 to the use transportation facility specifying server 20 and received by the use transportation facility specifying server 20 (S03, position information acquisition). Step).

  When location information from the mobile terminal 10 is received by the communication unit 21 of the use transportation facility specifying server 20, the information is first stored in the location information storage unit 22, and the travel route estimation unit 23 estimates the travel route. (S04, movement route specifying step) Further, in the spatially identical route determination unit 24, it is determined whether the movement route is the same as the past movement route (S05, movement route update step). Based on this, the information stored in the movement route storage unit 26 is updated by the movement route update unit 25 (S06, movement route update step).

  Subsequently, by comparing the information stored in the traffic network storage unit 27 with the travel route estimated by the travel route estimation unit 23, the spatially overlapping station identification unit can be identified. 28 (S07, use point specifying step), the station that becomes the boarding / exiting station is specified by the boarding / exiting station specifying unit from among the stations identified as being spatially overlapped (S08, use point specifying step) ).

  Further, based on the above result, the traffic route specifying unit 30 specifies the traffic route used by the user of the mobile terminal 10 (S09, used transportation facility specifying step), and the transfer point specifying unit 32 determines the transfer point. Identification is performed (S10, used transportation facility identification step). As a result, the use transportation facility used by the user of the mobile terminal 10 is specified, and the content corresponding to the user transportation use is acquired from the content storage unit 33 (S11). This content is transmitted from the use transportation facility specifying server 20 to the communication terminal 10 via the content distribution unit 34 and the communication unit 21 (S12). When the content is received by the communication unit 13 of the communication terminal 10, the display unit 14 The content is displayed and notified to the user (S13).

  As described above, the positioning at the mobile terminal 10, the specification of the used transportation facility based on the positioning result at the mobile terminal 10 in the used transportation facility specifying server 20, and the used transportation facility specifying server 20 based on the specified result of the used transportation facility. Distribution of information to the mobile terminal 10 ends.

<Effects of used transportation facility identification system and utilization transportation facility identification method>
According to the above-mentioned used transportation system specifying system 1 (used transportation system specifying server 20) and the used transportation system specifying method by this used transportation system specifying system 1, a plurality of pieces of position information acquired from the mobile terminal 10 carried by the user are used. Acquired by the transportation facility specifying server 20 and the moving route of the mobile terminal 10 is specified from this information. Then, after identifying the station used by the mobile terminal 10 based on the movement route of the mobile terminal 10 and the information indicating the position of the transportation station (use point) stored in the traffic network information storage unit 27, Based on the information of the station, the transportation facility used by the user of the mobile terminal 10 is specified. Thus, since only the use point of transportation is specified from the position information of the mobile terminal 10, and the use transportation used by the user of the mobile terminal 10 is specified based on the use point, for example, the position information and traffic Compared with the case where the transportation system used by the user is identified by comparing with the route map of the organization, the transportation system used can be identified from less information. Accordingly, it is possible to reduce the number of times of acquisition of the location information for specifying the used transportation facility in the mobile terminal, and it is possible to reduce the information transmitted to the used transportation facility specifying server. It is possible to specify the transportation facility used by the user while suppressing power consumption on the communication terminal side. In addition, the information used in the used transportation facility specifying server can be reduced, and the processing efficiency can be improved.

  In addition, the above-mentioned use transportation facility specifying server 20 specifies the use transportation facility using the route search algorithm after the boarding / exiting station specifying unit 29 specifies the boarding / exiting station. Therefore, even when there is little information obtained from the mobile terminal such as location information, it is possible to specify more accurately since the use transportation system is specified after the use section is specified in advance from the getting-on / off station.

  In addition, the above-mentioned use transportation facility specifying server 20 may be configured such that a plurality of boarding station candidates and alighting station candidates are selected. In this case, even if there are multiple transportation facilities or usage points that the user may use, use transportation points within the range of non-use distance are used as usage start points or use end points. By applying to the above, it is possible to prevent erroneous specification of the user's transportation system. In addition, if there are multiple stations on the same route that are used start points (boarding station candidates) or end points (getting off station candidates), other than the points closest to the starting point or ending point of the moving route on the same route By adopting a configuration that excludes the use point, the use point can be specified with higher accuracy.

  Further, in the above-described use transportation facility specifying server 20, the travel route storage unit 26 holds information related to the travel route estimated by the travel route estimation unit 23, and the travel route traveled in the past by the travel route update unit 25. Update information related to. Therefore, it is possible to estimate the travel route with higher accuracy based on the past travel route, and it is possible to specify the transportation system used based on this result.

  In addition, in the above-described use transportation facility specifying system 1, only the position information determined to be moving by the mobile terminal 10 is transmitted to the use transportation facility specifying server 20. Thereby, it can suppress transmitting the positional information on the time slot | zone presumed that the mobile terminal 10 is not moving to the utilization transportation organization specific server 20. FIG. Therefore, an increase in the amount of communication between the mobile terminal 10 and the use transportation facility specifying server 20 can be suppressed.

  As mentioned above, although preferred embodiment of this invention was described, the utilization transportation system specific system 1 which concerns on this invention can perform a various change.

  For example, all the functions related to the use transportation facility specifying server 20 may be included in one device, or each function may be distributed to different devices. For example, in the above embodiment, a case has been described in which the content according to the user's used transportation system is distributed in the used transportation facility specifying server 20, but the device that distributes the content and the server that identifies the used transportation facility are different devices. It may be.

  Moreover, although the said embodiment demonstrated the case where a utilization transportation was a train, the utilization transportation identification server and utilization transportation identification method which concern on this invention are applicable also to another transportation. For example, when the use transportation is a toll road such as an expressway, the entrance / exit of the toll road can be used as a use point for starting or ending use of the toll road. Further, when the transportation system used is an air route such as an airplane, the airport can be used as a use point for starting or ending use of the air route. Moreover, it is good also as an aspect which identifies a utilization transportation means combining said various transportation means.

  Moreover, although the said embodiment demonstrated the aspect which extracts a some station as a boarding station candidate and a boarding station candidate, and specifies a use transportation system, each boarding station candidate and a boarding station candidate are each extracted without extracting a plurality of stations. It is good also as an aspect which designates each station (For example, the nearest station from a starting point and an end point is designated as a boarding station and a getting-off station).

  Further, in the above embodiment, a mode is described in which the travel route is estimated, the information stored in the travel route storage unit 26 is updated, and then, the travel route used by the user is specified using the travel route information. However, a configuration using a past movement route is not essential. That is, it is also possible to perform a process of estimating a travel route based on only a plurality of pieces of position information transmitted from the mobile terminal 10 and specifying a use transportation facility.
