FIG. 2 conceptually shows the contents of the map database 156, the car route database 106, the train route database 107, the walking route database 108, and the facility database 109 described above.

  The map database 156 stores data (map image data) representing a map image transmitted to the mobile terminal 200 in a vector data format. The map image data may be stored in a raster data format such as a bitmap format or a JPEG data format instead of the vector data format. The map image data includes data representing the shape of topography, buildings, roads, and the like.

  Different types of route data are stored in the three types of route databases 106, 107, and 108. The vehicle route database 106 stores route data related to a route (a roadway) through which a vehicle can pass among traffic routes existing in an area corresponding to the map image represented by the map image data. The train route database 107 stores route data related to a route (railway) through which a train passes among traffic routes existing in an area corresponding to the map image represented by the map image data.

Based on the closed polygon CP, the area occupied by the facility can be calculated.

・ Operation of the map display system:
・ Information display processing:
FIG. 3 is a flowchart showing the processing steps of the information display processing. When the information display application is activated on the portable terminal 200, the portable terminal 200 and the server system 1000 cooperate to execute information display processing.

  The main control unit 210 of the mobile terminal 200 uses the GPS receiver 201 to acquire current position information indicating the current position. Then, main controller 210 periodically transmits the current position information to server system 1000 (step S110). Since the number of users of the mobile terminal 200 is not one, but the number of users is large, the server system 1000 periodically acquires the current position information of a large number of mobile terminals 200. The control unit 104 of the information providing server 100 generates and manages train user information based on a large number of current position information transmitted periodically (step S210).

  FIG. 4 is a flowchart showing the processing steps of train user information generation processing for generating train user information. The control unit 104 of the server system 1000 searches for an existing mobile terminal 200 along the train route (step S211). Specifically, the control unit 104 refers to the train route database 107, identifies a train route that is a target of train user information generation processing, and is within a predetermined distance range from the route (for example, within 2 m from the route) ) Is searched based on the acquired current position information.

  The control unit 104 generates a movement vector that represents a change in the current position of each searched mobile terminal 200 (step S212). Specifically, the movement vector represents the movement direction and movement speed of the mobile terminal 200. Specifically, the control unit 104 generates a movement vector based on a plurality of current position information transmitted from the same mobile terminal 200 in time series.

  The control unit 104 groups the mobile terminals 200 that are close to each other and whose movement vectors are within a predetermined range as the mobile terminals 200 that exist in the same train (step S213). FIG. 5 is a diagram for describing grouping of the mobile terminals 200. For example, the predetermined range of the movement vector is set to an error range that can be regarded as moving at the same speed in the same direction along the route of the target train.

  The control unit 104 identifies a train corresponding to a group of portable terminals 200 (hereinafter referred to as the same train group) present in the same train with reference to the timetable database 110 (step S214). In the timetable database 110, for example, the departure time at each train station is recorded for each train route, so the timetable database 110 and the current time and the position on the route of the same train group are referred to. For example, trains corresponding to the same train group can be identified.

  The control part 104 produces | generates the train characteristic information showing the characteristic of the identified train (step S215). The train characteristic information includes the speed of the train, the number of train cars, and the level of congestion of the train (the density of people in the train). The speed of the train is represented by, for example, an average value of the speeds represented by the movement vectors of the mobile terminals 200 belonging to the corresponding same train group. The number of train vehicles is estimated from the distribution in the direction along the route of the position of the mobile terminal 200 belonging to the corresponding same train group. For example, as shown in FIG. 5, when the points TP representing the position of the mobile terminal 200 are distributed over the length of three trains along the link LK representing the route, The number of vehicles is estimated to be three. The level of congestion of the train is estimated using, for example, the number of mobile terminals 200 belonging to the corresponding same train group distributed per length of one train along the route. For example, if the number of mobile terminals 200 per train is equal to or less than a first predetermined value, the congestion level is 1 (not congested), and if it exceeds the first predetermined value and is equal to or less than the second predetermined value. If congestion level 2 (congested) exceeds a second predetermined value, it is determined that congestion level 3 (very crowded) (first predetermined value <second predetermined value). .

  The control unit 104 repeats the train user information generation process described above for each train route to be managed at regular intervals, and manages the train operation status for the train route to be managed.

  Returning to FIG. 3, the description will be continued. The control unit 104 determines whether or not an accident has occurred in the train operation status (step S220). For example, (a) when the mobile terminal 200 belonging to the same train group stops at a position other than the station, or (b) the position of the mobile terminal 200 belonging to the same train group is recorded in the timetable database 110. When the operation is delayed for a predetermined time or more than the scheduled operation, (c) when the position of the mobile terminal 200 belonging to the same train group has been stopped for a certain time or more, the control unit 104 determines that an accident has occurred. Judgment can be made. Of course, it can be determined that an accident has occurred even when a plurality of events among (a), (b), and (c) occur simultaneously. If the control part 104 judges that the accident has not generate | occur | produced (step S220: NO), it will return to step S210 and will continue production | generation and management of train user information.

  On the other hand, when the control unit 104 determines that an accident has occurred (step S220: YES), the control unit 104 specifies the accident information target terminal (step S230). The accident information target terminal is a terminal that is a target of accident information to be described later, among many mobile terminals 200 that are currently transmitting position information to the server system 1000.

  FIG. 6 is a diagram for explaining determination of the accident information target terminal. For example, the control unit 104 recognizes, as an accident information target terminal, the mobile terminal 200 existing in the train in the accident spillover range where the influence of the generated accident is estimated to spill over. The accident spillover range can be, for example, within a train passing through a position where the accident has occurred with a predetermined probability or more. For example, as shown in FIG. 6, it is assumed that a train T1 stops at an accident in a place where an annular route C1 and two substantially straight routes L1 and L2 that intersect the route C1 and intersect each other exist. It is assumed that no accident has occurred in the other trains T2 to T7.

  In FIG. 6, the arrows shown inside the trains T1 to T7 represent the traveling direction of the train. In such a case, for example, the probability that the train T3 passes through the accident occurrence point (the location where the train T1 exists) is 1 (100%) because there is no branch from the current position of the train T3 to the accident occurrence point. Is done. On the other hand, since the train T2 may branch in three directions (station S13, station S4, and station S2) at the station S1, the probability that the train T3 passes through the accident occurrence point is 1/3 ( About 33 percent). Similarly, the probability that the trains T4, T6, and T7 pass through the accident occurrence point is 1/3. On the other hand, the probability of the train T5 passing through the accident occurrence point is 1/3 × 1/3 = 1/9 (about 11%) because the station S4 and the station S10 may branch in three directions. . Here, if the probability as a threshold is 20%, the mobile terminal 200 existing in the trains T2 to T4, T6, and T7 is determined to be an accident information target terminal, and the mobile terminal 200 existing in the train T5. The terminal 200 is determined not to be an accident information target terminal.

  The control unit 104 generates accident information, and transmits the generated accident information to the accident information target terminal (step S240). Accident information includes, for example, data of a train where an accident occurred and a train route image where the train where the accident information target terminal exists (for example, a map image of the area), trains and stations existing on the image. Data representing the degree of congestion of the train and the station, the number of vehicles on the train, the elapsed time since the occurrence of the accident, and data representing the contents of the accident. The content of the accident is acquired by, for example, the control unit 104 accessing a site (for example, a homepage of a railroad company) opened by an operation manager (for example, a railroad company) that operates the train in which the accident occurred.

  Instead, it may be obtained by accessing a site such as a blog established by the user of the mobile terminal 200. The degree of congestion at a station is determined based on, for example, the number (density) of mobile terminals 200 per area at the station. The range of the station can be recognized by the closed polygon CP stored in the facility database 109, and the control unit 104 can calculate the area of the station by the closed polygon CP. Further, the control unit 104 can calculate the mobile terminal 200 per area in the station by counting the number of mobile terminals 200 present in the closed polygon CP of the station and dividing the number by the area of the station. The degree of congestion at a station is represented by a plurality of levels (for example, three levels) using a predetermined threshold value, similarly to the degree of congestion at a train.

  The mobile terminal 200 that has become the accident information target terminal receives the accident information (step S120). When the accident information is received, the mobile terminal 200 presents the received accident information to the user (step S130). Specifically, the mobile terminal 200 displays accident information on the display panel 202.

  FIG. 7 is a first diagram showing the accident information displayed on the display panel 202. As an initial screen for displaying the accident image, first, an image of a train route where the train where the accident information target terminal exists, the train where the accident occurred, and the train where the accident information target terminal exists is displayed. In the example shown in FIG. 7, in the displayed image, an image of the train T6 where the mobile terminal 200 as the accident information target terminal is present is displayed. In addition, an image of the train T1 where the accident occurred is displayed together with a simple content of the accident. Here, the simple contents of the accident include a user interface that accepts whether or not to display the details of the accident from the user. When the display of the details of the accident is instructed by the user, further detailed accident information is displayed.

  FIG. 8 is a second diagram showing the accident information displayed on the display panel 202. As detailed accident information, as shown in FIG. 8, the type of accident (for example, personal injury), the elapsed time since the occurrence of the accident, the vicinity of the position where the accident occurred, and the mobile terminal 200 as the accident information target terminal exist. The degree of congestion of trains and stations near is shown. For example, the degree of congestion is displayed by displaying corresponding train and station images in different colors depending on the level. For example, the example shown in FIG. 8 shows that images of trains and stations are displayed in darker colors as the degree of congestion increases. Furthermore, as shown in FIG. 8, the number of vehicles of each train is displayed in the corner of the image of each train. In addition to the contents shown in FIG. 8, when the user of the mobile terminal 200 uses transportation, information relating to transportation used by the user himself, for example, the user himself / herself uses it. You may display the delay time with respect to the scheduled operation time of a transportation.

  In the present embodiment, the GPS receivers 201 of a large number of mobile terminals 200 and the control unit 104 of the server system 1000 that receives current position information from the mobile terminals 200 function as current position fluctuation information acquisition means. In the present embodiment, the control unit 104 of the server system 1000 functions as an operation status recognition unit, an abnormal spillover range determination unit, an abnormal information transmission unit, and an operation status information acquisition unit. In this embodiment, the timetable database 110 and the control unit 104 that refers to the timetable database 110 function as timetable information acquisition means.

  As described above, according to the present embodiment described above, the current position information of a large number of mobile terminals 200 is grouped in units of trains, and characteristics corresponding to the groups are presented to the user. As a result, the user can obtain useful information more conveniently. For example, as the characteristics of a group corresponding to a certain train, the image of the train is displayed in a color indicating the degree of congestion of the train, so the user avoids a congested train when changing trains, for example, It is easy to make decisions such as selecting a train that is not crowded.

  In addition, since a plurality of portable terminals 200 moving at substantially the same speed in the same direction along the route are grouped as portable terminals 200 held by users on the same train, the accuracy is high. Grouping is possible. In addition, train characteristics such as train speed and the number of vehicles can be accurately estimated based on the current position information of the mobile terminals 200 belonging to the same train group. In addition, since accident information is spontaneously transmitted to the accident information target terminal when an accident occurs, it is possible to automatically notify the accident information to a user who needs the accident information.

  Furthermore, since the operation status of the train can be recognized based on the movement vector representing the change in the current position of the mobile terminal 200 group, a new service for transmitting information related to the operation status of the train to the mobile terminal 200 can be provided. . Furthermore, since the operation status of the train is recognized with reference to the timetable database 110, the operation status can be recognized with higher accuracy. Furthermore, since the operation status information such as information on train abnormality is acquired from a site on the Internet and the train operation status is recognized, the operation status can be recognized with higher accuracy.

B. Variation:
-In the said Example, although the portable terminal 200 which exists in the same train is grouped as one group, the object of grouping is not restricted to a train unit. For example, the control unit 104 may group the mobile terminals 200 included in an area occupied by a facility (feature) such as a restaurant as one group. For example, when there is a mobile terminal 200 that has been stopped for a predetermined time or longer in a predetermined facility, the owner of the mobile terminal 200 is estimated to be a user of the facility. In addition, for example, when a plurality of mobile terminals 200 stopped from the inside of a predetermined store exist in a line, it is estimated that the store has a queue. Information for specifying the area occupied by the facility may be stored in the facility database 109 as a closed polygon CP, for example. For example, the control unit 104 may estimate facility characteristics such as restaurant congestion based on the number and speed of the mobile terminals 200 present in the facility. In this way, the mobile terminal 200 can present the characteristics of the facility in a manner that allows the user to discriminate such as displaying the color of the restaurant image in a different color depending on the degree of congestion. Then, for example, the user can use such group information as a reference when determining a restaurant to enter, which is convenient.

  In the above embodiment, the accident information target terminal is the mobile terminal 200 existing in the train. Instead of or in addition to this, the mobile terminal existing in a station within a predetermined distance from the accident occurrence position. The terminal 200 may be the accident information target terminal, or all the mobile terminals 200 existing within a predetermined distance from the accident occurrence position may be the accident information target terminals. Thus, the accident spillover range can be set arbitrarily.

  In the above embodiment, when an accident occurs, group characteristic information (in the embodiment, the degree of congestion of the train, the number of vehicles) is transmitted as accident information to the accident information target terminal. Instead, when the user operates and requests the mobile terminal 200, the group characteristic information (in the embodiment, the degree of congestion of the train, the number of vehicles) is transmitted to the mobile terminal 200. As good.

  -In the said Example, accident information transmitted to the portable terminal 200 contains the station information of a surrounding station, for example, the presence or absence of a restroom, the rest area (a coffee shop etc.) around a station in addition to group characteristic information. But it ’s okay. In this way, the user can easily select a measure corresponding to the accident, for example, to get off at the next station and take a break until the accident ends.

  In the above embodiment, when recognizing the operation status (including the abnormal status), in addition to the movement vector, the information of the timetable database 110 and the information acquired from the site on the Internet are used. It is possible to recognize the operation status without using it.

  -In the said Example, although the information regarding abnormality of a train operation is notified to a user by displaying it as an image on the display panel 202 of the portable terminal 200, instead of this, even if notified by voice good.

  In the above embodiment, part of the configuration realized by hardware may be replaced with software, and conversely, part of the configuration realized by software may be replaced by hardware. .

  The various databases 106 to 110 stored in the storage unit 105 may be appropriately combined as necessary. For example, the car route database 106 and the train route database 107 may be combined into one database. Moreover, various databases 106-110 are good also as one database.

  As mentioned above, although the Example and modification of this invention were demonstrated, this invention is not limited to these Example and modification at all, and implementation in a various aspect is possible within the range which does not deviate from the summary. It is.
