The current position information receiving unit 202a may receive time information such as the acquisition time of the current position information associated with the current position information transmitted from the terminal device 100. In the present embodiment, the terminal device 100 may be specified using the identification information, and the current position information receiving unit 202a may receive the identification information transmitted together with the current position information. The identification information may be acquired by analyzing the path of the network 300 or the like.

  The current position history storage unit 202b is a current position history storage unit that stores the history of the current position information received by the current position information receiving unit 202a in the position history database 206b. Here, the current position history storage unit 202b may store the history of the current position information received by the current position information receiving unit 202a in the position history database 206b in association with the time information. For example, the current position history storage unit 202b receives time information such as an acquisition time of the current position information received together with the current position information by the current position information receiving unit 202a, or current position information by the current position information receiving unit 202a. Time information such as the reception time may be stored in the position history database 206b in association with the current position information. The current position history storage unit 202b may store the identification information of the terminal device 100 received or acquired by the current position information receiving unit 202a in association with the current position information.

  Further, the speed direction calculation unit 202c is based on the displacement of the current position from the previous time based on the history of the current position information stored in the position history database 206b by the current position history storage unit 202b. It is a speed direction calculation means for calculating at least one. For example, the speed direction calculation unit 202c may calculate the direction from the previous current position to the current current position based on the history of the current position information stored in the position history database 206b, and corresponds to the current position information. The speed may be calculated by dividing the distance from the previous current position to the current current position by the time from the previous time to the current time on the basis of the time information stored additionally. Further, the speed direction calculation unit 202c may further calculate acceleration from the calculated change in speed.

  Further, the movement group determination unit 202d determines from the movement status of the current position indicated by the history of the current position information stored in the position history database 206b by the current position history storage unit 202b based on the network data stored in the network database 206a. These are movement group determination means for determining a movement group among the plurality of terminal devices 100-1 to 100-n. For example, the movement group determination unit 202d has the current position indicated by the current position information stored in the position history database 206b within a predetermined range (hereinafter referred to as “determination target area”) from the link of the network data. When at least one of acceleration, speed, and direction calculated by the speed direction calculation unit 202c or stored as current position information in the position history database 206b is the same or within a predetermined error range, You may determine with the same movement group. For example, the movement group determination unit 202d is within the determination target region from the current position based on the current position information of the terminal device 100 with respect to any one terminal device 100, and the speed and direction are the same or predetermined. Other terminal devices 100 that are within the error range may be searched from the position history database 206b. Further, the movement group determination unit 202d may use the traffic network data stored in the network database 206a as network data, and can be used at the current time based on the timetable information stored in the timetable database 206c. It may be limited to traffic network data of various transportation facilities.

  Here, the “determination target area” is an area that is a determination target of the movement group, and as an example, is an area having a predetermined width and length along the link of the network data. For example, the determination target area may be a width considering the width, road width classification, the number of lanes, and the like specified in the network data, or the length of a train, a bus, etc. specified in the traffic network data. Furthermore, the determination target region may be expanded not only to the region where the transportation facility as described above will exist, but also to a region including the positioning error range of the current position information. Here, the positioning error range may be a range indicating the radius or the like of the positioning error range in association with the current position information regarding longitude, latitude, and the like. As an example, when positioning by GPS is used, a positioning error range is set large at a point where reflection (multipath) of position information signals from GPS satellites is likely to occur due to surrounding buildings. A positioning error range may be set small at a point where the sky view is flat and the position information signal from the GPS satellite is easily received. Further, at each point, the positioning error range may be determined according to the number of GPS satellites that can receive the position information signal and the weather conditions. The positioning error range information may be stored in the storage unit 206 in advance, and the control unit 202 of the server apparatus 200 periodically sends the latest data via the network 300 to an external device (for example, a positioning error providing server). Etc.) and the information on the positioning error range stored in the storage unit 206 may be updated. In addition, the movement group determination unit 202d may calculate a positioning error range by applying a known positioning accuracy calculation technique. Note that, similarly to the positioning error range related to the current position described above, the predetermined error ranges for acceleration, velocity, and direction may be acquired using the above-described processing, technology, and the like.

  Here, when the current position of the current position information is within a predetermined range (determination target area) from the link of the network data, the movement group determination unit 202d further includes the time of the time information associated with the current position information. May be a condition for determining the same movement group (hereinafter referred to as a “movement group determination condition”). That is, the current position information transmitted from the plurality of terminal devices 100 may not be completely synchronized in the acquisition time, so there is a time difference in the timing of the acquired current position information between the plurality of terminal devices. Even in some cases, if it is in the determination target area within a predetermined time in consideration of the time difference, it may be added to the determination target of the same movement group.

  In addition, the movement group determination unit 202d may use a movement group determination condition that the current position stops at a stop position such as a station or a stop (bus stop) defined by the traffic network data stored in the network database 206a. Here, the movement group determination unit 202d does not set the determination condition for the movement group even when the current position stops at a stop position such as a traffic light, a stop sign, or a railroad crossing defined by road network data. That is, for example, when a user uses a bus as a transportation facility, the bus follows traffic rules on the road in the same manner as a general vehicle. For this reason, the movement group determination unit 202d does not consider the movement group when the current position stops at a common stop position with a general vehicle, but stops at a stop position (bus stop, station, etc.) specific to the relevant transportation It is determined as a moving group determination target.

  The movement group determination unit 202d stores the information of the movement group determined as described above (for example, identification information (ID) of the terminal device 100, the number of users, a history of the current position, etc. constituting the movement group). It may be stored in the unit 206.

  Also, the delay determination unit 202e compares the history of the current position information of at least one terminal device 100 belonging to the movement group determined by the movement group determination unit 202d with the timetable information stored in the timetable database 206c. Thus, it is a delay determining means for determining the transportation and the delay of the transportation. For example, the delay determination unit 202e uses the current position information of one terminal apparatus 100 among a plurality of terminal apparatuses 100 constituting the same movement group as the representative position information, and displays the time information associated with the representative position information. By comparing the displacement of the time and the current position with the time and position of the transportation system based on the timetable information stored in the timetable database 206c, the transportation system (such as a train or bus) used by the mobile group is compared. Route number) and delay information of the relevant transportation (presence / absence of delay, delay time, delay section, etc.) may be determined. Here, the delay determination unit 202e may use, as the representative position information, the average or the center of gravity of the plurality of current positions indicated by the current position information of the plurality of terminal devices 100 that constitute the same movement group.

  The determination result transmission unit 202f also determines the determination result of the movement group determined by the movement group determination unit 202d (for example, identification information (ID) of the terminal device 100 constituting the movement group, the number of users, delay information, etc. ) To the terminal device 100. Here, the determination result transmission unit 202f may transmit the determination result to the terminal device 100 configuring the mobile group, or may transmit the determination result to the terminal device 100 not configuring the mobile group. For example, the determination result transmission unit 202f may transmit advertisement information based on the determination result to the terminal device 100 that configures the mobile group. Delay information such as the above may be transmitted. In addition, the determination result transmission unit 202f may transmit a determination result (such as congestion status and delay information) to an external device (for example, a traffic information server that provides traffic information).

  The route search condition receiving unit 202g is route search condition receiving means for receiving a route search condition transmitted from the terminal device 100 and including at least a departure place and a destination.

  The route search unit 202h searches for a route from the departure place to the destination that satisfies the route search condition received by the route search condition reception unit 202g based on the network data stored in the network database 206a. This is route search means for calculating route information of a route. Here, the route search unit 202h obtains the route information of the route from the departure point to the destination that satisfies the route search condition received by the route search condition reception unit 206g based on the network data stored in the network database 206a. Alternatively, the calculation may be performed so as to avoid the delay interval determined by the delay determination unit 202e and the congestion interval based on the determination result (number of users, etc.) determined by the movement group determination unit 202d. Note that the route search unit 202h not only calculates route information of a route that avoids a delay interval or a congestion interval, but also indicates delay information (delay time, etc.), congestion status, etc. in association with the calculated route information route. Information may be stored in the route information. In addition, the route search unit 202h may search for a route that satisfies these specified conditions when the route search conditions further include specified information such as departure time, arrival time, waypoint, moving means, route used, and the like. Good. The route information calculated by the route search unit 202h includes departure point information / destination information, required time (for example, time including delay time), travel distance, departure time, arrival time (for example, delay time). Information such as added time, weather information, transportation means information, waypoints, waypoint passage times, and routes used.

  The route information transmission unit 202i is route information transmission means for transmitting the route information calculated by the route search unit 202h to the terminal device 100 that is the transmission source of the route search condition.

May be acquired as the current position information of the person.

  Then, the current location information transmission unit 102b of the terminal device 100 transmits the current location information acquired by the current location information acquisition unit 102a to the server device 200 (step SA-2). Here, the current position information transmission unit 102b may transmit the time information of the acquisition time at which the current position information is acquired to the server apparatus 200 in association with the current position information. Further, the current position information transmission unit 102b may transmit the identification information of the terminal device 100 to the server device 200 together with the current position information. Here, the current position information transmission unit 102b may transmit the current position information to the server device 200 in accordance with the update of the current position information acquired by the current position information acquisition unit 102a.

The current location information receiving unit 202a may receive time information and identification information of an acquisition time transmitted together with the current location information, or may acquire identification information by analyzing a path of the network 300 or the like. Good.

  Then, the current position history storage unit 202b of the server device 200 stores the history of the current position information received by the current position information receiving unit 202a in the position history database 206b (step SA-4). Here, the current position history storage unit 202b may store the history of the current position information received by the current position information receiving unit 202a in the position history database 206b for each terminal device 100 (identification information thereof).

Then, the speed direction calculation unit 202c divides the calculated movement distance ΔL by a time ΔT (= t2−t1) from time t1 to time t2, thereby indicating a speed V (indicated by the length of the arrow in the drawing). May be calculated. The speed direction calculation unit 202c may further calculate acceleration from the calculated change in the speed V, and calculates the direction (direction) from the point (current position) at time t1 to the point (current position) at time t2. Thus, the velocity V may be expressed as a vector. The speed direction calculation unit 202c may store the acceleration, speed, and direction calculated in this way in the position history database 206b in association with the current position information at time t2.

  Returning to FIG. 3 again, the movement group determination unit 202d of the server device 200 moves the current position indicated by the history of the current position information stored in the position history database 206b based on the network data stored in the network database 206a. From these, the movement group among the plurality of terminal devices 100-1 to 100-n is determined (step SA-5). For example, the movement group determination unit 202d has the current position indicated by the current position information stored in the position history database 206b within a predetermined determination target area from the link of the network data, and is calculated by the speed direction calculation unit 202c. Or, when at least one of acceleration, velocity, and direction stored as current position information in the position history database 206b is the same or within a predetermined error range, it may be determined as the same movement group Good. Here, FIG. 5 is a diagram schematically illustrating an example of a movement group determination method by the movement group determination unit 202d. In FIG. 5, the positions of the square, triangle, and circle symbols that are painted black are based on the current position information of the plurality of terminal devices 100-1 to 100-n at a certain time (or within a predetermined time from the time). The point (current position) is shown. The length of the arrow indicates the speed (speed), and the direction of the arrow indicates the direction (direction). As shown in the figure, for easy understanding, the point logs (history of current position information) are classified into squares, triangles, and circles according to the speeds v1 to v3.

  As shown as an example in FIG. 5, first, the movement group determination unit 202d sets a predetermined range from the link of the traffic network data as a determination target region based on the current position indicated by the current position information, and then determines a predetermined time from the position history database 206b. A point log (a history of current position information) within (for example, a time from time t1 to t2) is extracted. For example, when train route network data is used as the traffic network data of the transportation facility, the movement group determination unit 202d determines the determination target region based on the width (track width), the train width, and the like specified in the route network data. May be set. In addition, the movement group determination unit 202d may set not only the region where the transportation facility is estimated to exist, but also a determination target region that is expanded to a region that takes into account the positioning error range of the current position information.

  Furthermore, the movement group determination unit 202d calculates the extracted point log (current position information history) in the determination target region, calculated by the speed direction calculation unit 202c, or stored as current position information in the position history database 206b. In addition, when there are a predetermined number or more of the same speed and direction (or within a predetermined error range), the terminal devices 100 are determined as the same movement group. Note that the broken line (block determination area) in FIG. 5 is a group of terminal devices that have the same speed (v3) and direction (rightward) and are determined to form the same movement group.

  The determination of the movement group by the movement group determination unit 202d as described above is preferably performed in a time zone that does not include the stoppage time of the transportation facility. In other words, if the transportation system is a train between stations, if it is a bus, it is determined by the point log from the stop to the stop. Can be determined. In order to prevent erroneous determination, it is determined that the movement status of the current position of the terminal device 100 determined to be a movement group is stopped at the same stop position (station or stop) in a predetermined time zone. It may be added to the conditions. Here, FIG. 6 is a diagram schematically illustrating a method of determining a moving group that is on a bus on a road.

  As shown in FIG. 6, the movement group determination unit 202d determines that the current position has stopped at a stop position such as a stop (bus stop) defined by the bus traffic network data stored in the network database 206a. It is good. Here, the movement group determination unit 202d does not make the same movement group even when the current position stops at a stop position such as a traffic light, a stop sign, or a railroad crossing defined by road network data. Also, the movement group determination unit 202d does not use the same movement group determination condition because it is predicted that the current position is a mere traffic jam even when the current position stops other than the stop position defined by the road network data or the like. . In this way, with regard to transportation such as buses, there are other users who ride on ordinary vehicles on the same road. As a result, it cannot be distinguished from the point log of other users who are traveling at the same speed and direction as the bus, which causes a misjudgment. Therefore, it is possible to more accurately determine a moving group on the same public transportation by limiting the moving group to those that stop at a stop position such as a stop defined in the traffic network data. .

  As described above, the movement group determination unit 202d determines the determination result of the determined movement group (identification information (ID) of the terminal device 100 configuring the movement group, the number of users, the number of movement groups, and the speed). Get congestion status). Here, the delay determination unit 202e of the server device 200 includes a history of current location information of at least one terminal device 100 belonging to the movement group determined by the movement group determination unit 202d, and a timetable stored in the timetable database 206c. The information and the information may be compared to determine the transportation facility and the delay of the transportation facility. For example, the delay determination unit 202e uses the current position information of one terminal apparatus 100 among a plurality of terminal apparatuses 100 constituting the same movement group as the representative position information, and displays the time information associated with the representative position information. The displacement of the time and the current position is compared with the time of the transportation and the position of the station based on the timetable information stored in the timetable database 206c, and the transportation (train or bus) used by the mobile group is compared. Route number), and delay information (delay presence / absence, delay route, delay section, delay time, etc.) of the transportation facility. Here, the delay determination unit 202e may use, as the representative position information, the average or the center of gravity of the plurality of current positions indicated by the current position information of the plurality of terminal devices 100 that constitute the same movement group.

  Returning to FIG. 3 again, the determination result transmission unit 202f of the server device 200 determines the determination result of the movement group determined by the movement group determination unit 202d (for example, the identification information (ID) of the terminal device 100 constituting the movement group, The number of users) is transmitted to the terminal device 100 (step SA-6). Here, the determination result transmission unit 202f may transmit the determination result (delay information such as presence / absence of delay, delay route, delay section, delay time, etc.) determined by the delay determination unit 202e to the terminal device 100. The determination result transmission unit 202f may transmit the advertisement information based on the determination result to the terminal device 100 configuring the mobile group, or may transmit the congestion status based on the determination result to the terminal device 100 not configuring the mobile group. Alternatively, the delay information may be transmitted to the terminal device 100 in which traffic information is registered in advance as a distribution target. In addition, the determination result transmission unit 202f may transmit a determination result (such as congestion status and delay information) to an external device (for example, a traffic information server that provides traffic information).

  Then, the determination result receiving unit 102c of the terminal device 100 receives the movement group determination result and delay information transmitted from the server device 200 (step SA-7). The determination result receiving unit 102c receives the received determination result (identification information (ID) of the terminal device 100 constituting the mobile group, the number of users, etc.), delay information (delay route, delay section, delay time, etc.), etc. May be stored in the storage unit 106.

  And the determination result output part 102d of the terminal device 100 outputs the determination result, delay information, etc. of the movement group received by the determination result receiving part 102c to the output part 114 (step SA-8). For example, based on the identification information (ID) of the moving group, the determination result output unit 102d outputs a display such as “Mr. May be. In addition, the judgment result output unit 102d is based on the delay information (delay route, delay section, delay time, etc.) “There is a delay of ○ minutes in the section from the A station to the B station on the XX line. Or the like may be output to the output unit 114. In addition, the determination result output unit 102d outputs to the output unit 114 a display such as “There is a traffic jam or congestion near C on the national highway No. ○”, a voice output, or the like according to the congestion state of the determination result. May be.

  The above is an example of the process of the position specifying system in the first embodiment. In the above example, a case has been described in which a mobile group that uses the same public transportation system is mainly determined using a transportation network such as a public transportation system. However, the present invention is not limited to this. It is also possible to detect a moving group or a congested area that is not using the same transportation system but is a lump (group) due to traffic congestion or congestion.

[Route information provision processing]
Next, an example in which the server apparatus 200 provides route information based on the determination result of the movement group and the delay information will be described as an example of the usage application of the determination result of the movement group determined as described above. Here, FIG. 7 is a diagram illustrating an example of route information providing processing in the first embodiment.

  First, the route search condition transmission unit 102e of the terminal device 100 transmits a route search condition including at least a departure place and a destination to the server device 200 (step SB-1). Here, the route search condition may be information such as a departure place and a destination stored in the storage unit 106 in advance, and information such as a departure place and a destination input by the user via the input unit 116. It may be. For example, the route search condition transmission unit 102e may set a position coordinate or the like input by the user via the input unit 116 as a departure point, a destination, or a waypoint. Further, the route search condition transmission unit 102e may set the current location information of the user of the terminal device 100 acquired by the current location information acquisition unit 102a as the departure point of the route search condition. For example, the route search condition transmission unit 102e causes the user to specify the coordinates on the map display screen displayed on the output unit 114 via the input unit 116 (for example, the designation operation of the touch panel type input unit 116). Etc. may be set as a departure point, a destination, or a transit point. Further, the route search condition transmission unit 102e may use the address, latitude / longitude, facility name, and the like input via the input unit 116 such as a keyboard as the starting point and destination of the route search condition.

  Then, the route search condition receiving unit 202g of the server device 200 receives the route search condition including at least the departure place and the destination transmitted from the terminal device 100 (step SB-2).

  Then, the route search unit 202h of the server device 200, based on the network data stored in the network database 206a, satisfies the route search condition received by the route search condition reception unit 206g and the route from the departure point to the destination. The route information is calculated so as to avoid the delay interval determined by the delay determination unit 202e and the congestion interval based on the determination result (number of users, etc.) determined by the movement group determination unit 202d (step SB-3). . For example, when calculating a route for walking, the route search unit 202h calculates route information so as to avoid a pedestrian crowded section determined by the movement group determination unit 202d using road network data. To do. The route searching unit 202h replaces the route information of the route that avoids the delay interval and the congestion interval with each other, calculates delay information (delay time, etc.), congestion status, etc. in association with the calculated route information route. The indicated information may be stored in the route information.

  Then, the route information transmission unit 202i of the server device 200 transmits the route information calculated by the route search unit 202h to the terminal device 100 that is the transmission source of the route search condition (step SB-4).

  Then, the route information receiving unit 102f of the terminal device 100 receives the route information transmitted from the server device 200 (step SB-5).

  Then, the route information output unit 102g of the terminal device 100 performs route guidance via the output unit 114 based on the route information received by the route information receiving unit 102f (step SB-6). Here, the route information output unit 102g controls the user to select, through the input unit 116, one route for executing route guidance from among the received route information regarding the plurality of routes, and the selected route. Route guidance may be executed for. Further, the route information output unit 102g may cause the output unit 114 to display a display screen in which the guide route of the route information and the current position based on the current position information of the terminal device 100 are superimposed on the map data. In addition, the route information output unit 102g outputs voice guidance data associated with the traveling direction at a guidance point such as a branch point on the guidance route included in the route information via the output unit 114 by voice output. Route guidance may be executed.

  The above is an example of the route information provision processing in the first embodiment.

[Processing of server apparatus 200 (server-driven type)]
Next, an example of the processing of the server device 200 in the second embodiment configured as described above will be described in detail with reference to FIG. FIG. 9 is a flowchart illustrating an example of processing of the server device 200 according to the second embodiment. As a premise, in the plurality of terminal devices 100, the position information signal received from the position transmission device 500 by the position acquisition unit 112 and the data such as the speed and direction acquired by the sensor of the position acquisition unit 112 are updated. The current position information acquisition unit 202j of the server apparatus 200 stores the current position information acquired based on the received position information signal or the like in the position history database 206b as needed. Yes.

  As shown in FIG. 9, first, the current location information acquisition unit 202j of the server device 200 acquires the current location information of the user based on the location information signal and the like transmitted from each terminal device 100 (step SC- 1). Here, the current position information acquisition unit 202j receives, from the terminal device 100, information such as the acceleration, speed, and direction (azimuth) of the terminal device 100 detected by the direction sensor, the acceleration sensor, or the like of the position acquisition unit 112. May be included in the current position information.

  Then, the current position history storage unit 202b of the server device 200 stores the history of the current position information acquired by the current position information acquisition unit 202j in the position history database 206b (step SC-2). Here, the current position history storage unit 202b may store the history of the current position information received by the current position information receiving unit 202a in the position history database 206b for each terminal device 100 (identification information thereof). The current position information may be stored in the position history database 206b in association with the time information of the acquisition time at which the current position information is acquired. Here, when the current position information does not include information such as acceleration, speed, direction, etc., the speed direction calculation unit 202c based on the current position information history stored in the position history database 206b, Depending on the displacement of the position, at least one of acceleration, speed, and direction may be calculated and stored in the current position information.

  Based on the network data stored in the network database 206a, the movement group determination unit 202d of the server device 200 uses a plurality of movement states of the current position indicated by the history of the current position information stored in the position history database 206b. The movement group in the terminal device 100 is determined (step SC-3). For example, the movement group determination unit 202d has the current position indicated by the current position information stored in the position history database 206b within a predetermined determination target area from the link of the network data, and is calculated by the speed direction calculation unit 202c. Or, when at least one of acceleration, velocity, and direction stored as current position information in the position history database 206b is the same or within a predetermined error range, it may be determined as the same movement group Good. Here, when the current position of the current position information is within the determination target area from the link of the network data, the movement group determination unit 202d further determines that the time of the time information associated with the current position information is within a predetermined time. It is good also as a judgment condition of a movement group. In addition, the movement group determination unit 202d may use a movement group determination condition that the current position stops at a stop position such as a station or a stop (bus stop) defined by the traffic network data stored in the network database 206a.

By comparing the displacement of the time and the current position with the time and position of the transportation system based on the timetable information stored in the timetable database 206c, the transportation system (such as a train or bus) used by the mobile group is compared. Route number) and delay information of the relevant transportation (presence / absence of delay, delay time, delay section, etc.) may be determined. Here, the delay determination unit 202e may use, as the representative position information, the average or the center of gravity of the plurality of current positions indicated by the current position information of the plurality of terminal devices 100 that constitute the same movement group.

  Then, the display screen generation unit 202m of the server device 200 generates a display screen indicating the determination result of the movement group determined by the movement group determination unit 202d (Step SC-4). As an example, the display screen generation unit 202m determines, based on the determination result of the movement group determined by the movement group determination unit 202d (for example, identification information (ID) of the terminal device 100 configuring the movement group) , XX is on board ”may be generated, and depending on the congestion status based on the determination result of the mobile group (number of users making up the mobile group, etc.) A display screen including a notation such as “congestion or congestion is occurring in the vicinity of C on National Route ○” may be generated. Further, the display screen generation unit 202m determines that “in the section from the A station to the B station on the line XX, based on the delay information (delay route, delay section, delay time, etc.) determined by the delay determination unit 202e. A display screen including a notation such as “There is a minute delay” may be generated. In addition, the display screen generation unit 202m may generate a display screen including an advertisement based on the determination result of the movement group and the delay information.

  Then, the display control unit 202n of the server device 200 transmits the control data including the display screen generated by the display screen generation unit 202m to the terminal device 100, so that the display is performed via the display unit 118 of the terminal device 100. A screen is displayed (step SC-5).

  The above is an example of the process of the server apparatus 200 in the second embodiment. Note that the server device 200 may repeatedly perform the above-described processing. For example, when the determination result of the movement group determined according to the update of the current position information is changed, the server device 200 is based on the changed determination result. A display screen may be generated and displayed on the display unit 118 of the terminal device 100.
