Boarding / alighting judgment device, boarding / alighting judgment method and boarding / alighting judgment program

The present invention relates to a boarding / alighting determination device, a boarding / alighting determination method, and a boarding / alighting determination program.

A mobile phone or an in-vehicle navigation device can receive radio waves from a GPS (Global Positioning System) artificial satellite and know its own position information. There is known a technique for determining whether or not a pedestrian is in a vehicle by comparing the position information of a mobile phone carried by a pedestrian with the position information of a navigation device mounted on the vehicle.

The boarding / alighting determination method of Patent Document 1 determines that a pedestrian is in the vehicle when the mobile phone exists within a radius n centered on the vehicle. Further, the boarding / alighting determination method determines that a pedestrian is not in the vehicle when the mobile phone does not exist within a radius m (m> n) centered on the vehicle. In the position information notification system of Patent Document 2, when the mobile terminal device exists in the vicinity of the vehicle and the moving speed of the mobile terminal device exceeds the threshold value, the pedestrian is not walking on the sidewalk but is in the vehicle. Judge that you are on board.

The vehicle in the above-mentioned

Patent Documents

1 and 2 is an automobile. Similarly, in railway vehicles, there is a need to know whether or not a user (passenger) is in the vehicle. Many railway stations are equipped with gate devices such as ticket gates. Many users have the gate device read the transportation IC card at the boarding station and the getting-off station. Then, it can be estimated that the user was in the vehicle from the boarding station to the getting-off station.

This conventional method attempts to know the boarding section from the reading result of the gate device at each station, and not only does not assume that the fare will be charged according to the difference in the waypoints, but also fraud such as boarding a kiseru. Can't deal with. In addition, railway operators bear a large amount of costs for maintaining equipment such as deposit machines, ticket gates, and checkout machines. If the user can accurately determine the boarding section simply by getting on and off the vehicle, the equipment maintenance cost will be greatly reduced.

The technologies of

Hereinafter, a mode for carrying out the present invention (referred to as “the present embodiment”) will be described in detail with reference to figures and the like. The boarding / alighting determination device of the present embodiment is applied to a vehicle traveling on a railway line and a user thereof. However, this is only an example, and the present invention can be applied to other means of transportation such as a fixed-route bus. A base where users get on and off transportation is generally called a "stop". The “station” of the present embodiment is an example of a stop.

(Getting on and off judgment device)
FIG. 1 is a diagram showing a configuration of a boarding / alighting determination device. The boarding / alighting determination device 1 is a general computer, and includes a central control device 11, an input device 12 such as a mouse and a keyboard, an output device 13 such as a display, a main storage device 14, an auxiliary storage device 15, and a communication device 16. These are connected to each other by a bus. The auxiliary storage device 15 stores departure time information 31, vehicle position information 32, station position information 33, user information 34, and transfer information 35 (all of which will be described in detail later).

The determination preparation unit 21 and the boarding / alighting determination unit 22 in the main storage device 14 are programs. The central control device 11 reads these programs from the auxiliary storage device 15 and loads them into the main storage device 14, thereby realizing the functions of the respective programs (details will be described later). The auxiliary storage device 15 may have a configuration independent of the boarding / alighting determination device 1. The boarding / alighting determination device 1 can communicate with the operation management system 5, the train control system 6, and the radio base station 7 via the network 2. The radio base station 7 can communicate with the vehicle 3 and the mobile terminal device 4.

The operation management system 5 is a delay information which is a difference between which vehicle is scheduled to arrive and depart at which station when and which station (scheduled timetable information), which vehicle actually arrives and departs when and which station (actual timetable information), and the difference between the two. , And manage accident information, etc. The train control system 6 originally controls the start / stop of the vehicle, the traveling speed, the opening / closing of the entrance / exit door, the air conditioning in the vehicle, and the like, and also controls the traffic lights of the line section. Often, the crew drives the vehicle. In this case, the train control system 6 performs auxiliary control such as speed monitoring and emergency braking operation.

Vehicle 3 is a train of one train. Trains in urban areas may include more than 10 cars. The vehicle 3 has a GPS device 42 at an intermediate point between its front and rear lengths. The vehicle 3 stores the GPS application 41 as software for controlling the GPS device 42 at an arbitrary location. The GPS device 42 receives radio waves from a plurality of artificial satellites (not shown) and calculates its own position information (latitude and longitude). The mobile terminal device 4 is carried by each user. The mobile terminal device 4 has a GPS device 43. The mobile terminal device 4 stores a GPS application 44 as software for controlling the GPS device 43. The GPS device 43 receives radio waves from a plurality of artificial satellites and calculates its own position information.

The GPS device 42 of the vehicle 3 and the GPS device 43 of the mobile terminal device 4 transmit their own position information to the boarding / alighting determination device 1 via the radio base station 7 and the network 2.

(Positional relationship between user and vehicle)
FIG. 2 is a diagram for explaining the positional relationship between the user and the vehicle. At the time of boarding 51a, the user 45 is just before boarding the vehicle 3 at a certain station. At this point, the boarding / alighting determination device 1 acquires the position information of the GPS device 42 of the vehicle 3 and the position information of the GPS device 43 of the mobile terminal device 4, and displays the results on the output device 13 in FIG. 52a. ..

The circle 46 is a circle centered on the position of the GPS device 42 and having the front-rear length of the vehicle 3 as the diameter. The circle 47 is a circle centered on the position of the GPS device 43. The diameter of the circle 47 can be set arbitrarily, but it is desirable that the diameter of the circle 47 is smaller than that of the circle 46 from the viewpoint of visibility. The movement locus 53 is a locus in which the GPS device 42 of the vehicle 3 moves. Here, the circle 47 is outside the circle 46. This indicates that the user 45 is not in the vehicle 3. The position of the vehicle 3 is represented by a circle 46 instead of an elongated rectangle or the like because the direction of the vehicle 3 changes variously (360 degrees) according to the route condition of the line section.

At 51b during boarding, user 45 is boarding vehicle 3. At this point, the boarding / alighting determination device 1 acquires the position information of the GPS device 42 of the vehicle 3 and the position information of the GPS device 43 of the mobile terminal device 4, and displays the results on the output device 13 in FIG. 52b. .. Here, the circle 47 is inside the circle 46. This indicates that the user 45 is in the vehicle 3.

At the time of getting off 51c, the user 45 has just got off from the vehicle 3 at another station. At this point, the boarding / alighting determination device 1 acquires the position information of the GPS device 42 of the vehicle 3 and the position information of the GPS device 43 of the mobile terminal device 4, and displays the results on the output device 13 in the schematic diagram 52c. .. Here, the circle 47 is outside the circle 46. This indicates that the user 45 is not in the vehicle 3.

(User movement at the station)
FIG. 3 is a diagram illustrating the movement of the user at the station. The platform 62 of station a is arranged along the track 61. “P01” and the like in FIG. 3 are user IDs as identifiers that uniquely identify the user. In the present embodiment, since the user and the mobile terminal device 4 have a one-to-one correspondence, the user ID is also an identifier that uniquely identifies the mobile terminal device 4. Users P01, P02 and P03 are waiting for the vehicle to arrive on platform 62. Users P04 and P05 are approaching platform 62.

It is assumed that the users P01, P02, P03 and P04 are logged in to the boarding / alighting determination device 1, and the user P05 is not logged in. Login is to establish communication for the purpose of transmitting position information between the GPS device 43 of the mobile terminal device 4 and the boarding / alighting determination device 1. Further, it is assumed that the boarding / alighting determination device 1 has acquired the position information of station a in advance. At this time, the boarding / alighting determination device 1 can display the users P01, P02, P03 and P04 on the output device 13 against the background of the track 61 and the platform 62. The boarding / alighting determination device 1 cannot display the user P05. In FIG. 3, the display of the mobile terminal device 4 is omitted (the same applies to FIGS. 4 and 5).

FIG. 4 is also a diagram illustrating the movement of the user at the station. Vehicle 3 arrived at station a, and users P01 and P02 boarded vehicle 3 from platform 62. User P03 did not get on the vehicle 3. Users P04 and P05 are even closer to platform 62 than in FIG. Then, other than the user P05, the user is logged in to the boarding / alighting determination device 1. After that, the vehicle 3 departed from station a toward the next station (in the direction of travel 63), and eventually the tail end of the vehicle 3 reached the end of the platform 62.

At this time, the boarding / alighting determination device 1 can display the users P01, P02, P03 and P04 on the output device 13 against the background of the track 61, the platform 62 and the vehicle 3. The boarding / alighting determination device 1 cannot display the user P05. The circle 46 is a circle centered on the position of the GPS device 42 of the vehicle 3 and having the front-rear length of the vehicle 3 as the diameter. The users P01 and P02 in FIG. 4 correspond to the circle 47 in 51b during boarding in FIG.

FIG. 5 is also a diagram illustrating the movement of the user at the station. Vehicle 3 arrived at station b, and user P01 got off from vehicle 3 to platform 64. The user P02 remains in the vehicle 3. User P03 continues to stand by at platform 62 at station a. Users P04 and P05 are in substantially the same positions as in FIG. It is highly possible that the users P04 and P05 happen to be in the vicinity of station a for a purpose other than the purpose of getting on the vehicle 3. Users other than user P05 are logged in to the boarding / alighting determination device 1. After that, the vehicle 3 departed from station b toward the next station, and eventually the tail of the vehicle 3 reached the end of the platform 64.

At this time, the boarding / alighting determination device 1 can display the users P01, P02, P03 and P04 on the output device 13 against the background of the track 61, the platform 62, the platform 64 and the vehicle 3. The circle 46 is a circle centered on the position of the GPS device 42 of the vehicle 3 and having the front-rear length of the vehicle 3 as the diameter. The user P02 in FIG. 5 corresponds to the circle 47 in the boarding 51b of FIG. 2, and the user P01 corresponds to the circle 47 in the disembarking 51c of FIG.

In general, the movement of the user while the vehicle is stopped at the station and the door is open is not simple. A user gets on a vehicle from a platform and then immediately gets off the same platform again. One user disembarks from a vehicle to the platform and then immediately re-boardes the same vehicle. Such movements often occur due to misunderstandings or schedule changes of users, but to ensure safety during congestion and regular driving, users who do not plan to get off at the station are once disembarked on the platform. I often let them do it.

Then, the timing of confirming that a certain user has boarded or disembarked (at the time of boarding / alighting confirmation) becomes a problem. The entrance door may be reopened immediately after it is closed. Therefore, the time when the boarding / alighting door is closed is not suitable as the time when boarding / alighting is confirmed.

The user can jump on or off from the unlocked door of the passenger car deck with a part of the vehicle hanging on the platform. Such a phenomenon is rarely seen in Japan today, but it is common in some developing countries. Therefore, the time when such jumping and the like is definitely impossible is suitable as the time when getting on and off is confirmed.

The time when boarding / alighting is confirmed in the present embodiment is the time when the tail of the vehicle reaches the end of the platform immediately after the vehicle departs from the station, that is, the time when the vehicle completely leaves the station. By defining the boarding / alighting confirmation time point in this way, the effect that the circle 46 indicating the position of the vehicle 3 does not overlap with the platform also occurs.

(Departure time information)
FIG. 6 is a diagram showing an example of departure time information 31. In the departure time information 31, the line section name is in the line section name column 102, the vehicle ID is in the vehicle ID column 103, and the departure time column 104 is associated with the line section ID stored in the line section ID column 101. The departure time is memorized.

The line section ID in the line section ID column 101 is an identifier that uniquely identifies the line section. A line section is a line of vehicles that can be moved without changing trains. A railroad operator may have multiple lines.
The line section name in the line section name column 102 is the name of the line section.

The vehicle ID in the vehicle ID column 103 is an identifier that uniquely identifies the vehicle. The vehicle of this embodiment is a train composed of one or a plurality of vehicle bodies. The physically same vehicle may drive back and forth between the terminal stations many times during the day. In this case, even if the vehicles are physically the same, a different vehicle ID is assigned each time the vehicle is turned back.
The departure time in the departure time column 104 is the departure time of the vehicle at each station (arrival time only at the terminal station). Although not represented in FIG. 6, the departure time is actually stored in seconds.

The departure time information 31 is created by the operation management system 5 for each line section and for each up and down route. The departure time information 31b in FIG. 6 is the departure time information 31 for the “B line”. In Japan, unless there are special circumstances, the vehicle operates on a regular basis according to the departure time information 31 created in advance. However, due to congestion, accidents, bad weather, etc., the future part of the departure time information 31 created in advance may be reviewed. The operation management system 5 always maintains the departure time information 31 of each line section in the latest state after the review.

(Vehicle position information)
FIG. 7 is a diagram showing an example of vehicle position information 32. In the vehicle position information 32, the line section ID is in the line section ID column 112, the latest position acquisition time is in the latest position acquisition time column 113, and the position information column is associated with the vehicle ID stored in the vehicle ID column 111. The position information is stored in 114, and the home departure time after departure is stored in the home departure time column 115 after departure.

The vehicle ID in the vehicle ID column 111 is the same as the vehicle ID in FIG.
The line section ID in the line section ID column 112 is the same as the line section ID in FIG.
The latest position acquisition time in the latest position acquisition time column 113 is the latest time when the position information of the vehicle is acquired. “#” Indicates a different value abbreviated (the same applies hereinafter).

The position information in the position information column 114 is the position information (latitude and longitude) of the GPS device 42 of the vehicle 3.
The post-departure platform departure time column 115 of the post-departure platform departure time column 115 is the time between the time when the vehicle 3 departs from the station and the time when boarding / alighting is confirmed. The boarding / alighting determination device 1 calculates the platform departure time after departure based on the front-rear length of the vehicle 3, the length of the platform, and the speed (acceleration). The time to leave the platform after departure differs for each vehicle and each station. The boarding / alighting determination device 1 stores in the relevant column the post-departure platform departure time calculated based on past experience for each vehicle and each station. Therefore, "#" in the column is an n-dimensional vector. n is the number of stations belonging to the line section. In order to simplify the process, the departure time from the platform after departure may be constant for each line section regardless of the vehicle and the station. In this case, "#" is a one-dimensional scalar.

(Station location information)
FIG. 8 is a diagram showing an example of station position information 33. In the station position information 33, the station name is in the station name column 122, the position information is in the position information column 123, and the line section ID is in the line section ID column 124 in association with the station ID stored in the station ID column 121. It is remembered.
The station ID in the station ID column 121 is an identifier that uniquely identifies the station.
The station name in the station name column 122 is the name of the station.

The position information in the position information column 123 is the position information (latitude and longitude) of the station.
The line section ID in the line section ID column 124 is the same as the line section ID in FIG. In some cases, a plurality of line section IDs are stored in the column (in the case of a transferable station).

(User information)
There are two types of user information created by the boarding / alighting determination device 1. One is the user information (at the time of login) 34 in FIG. 9, and the other is the user information (at the time of boarding / alighting confirmation) 34b in FIGS. 10, 11 and 12. The boarding / alighting determination device 1 creates a record of user information (at the time of login) 34 for each user when the mobile terminal device 4 of each user is logged in. After that, the boarding / alighting determination device 1 tracks the stop of a specific vehicle at each station, and collects user information (boarding / alighting confirmation time) 34b for each user related to the vehicle each time the boarding confirmation time arrives. create. The structure of each column of both is the same.

FIG. 9 is a diagram showing an example of user information (at the time of login) 34. 10, FIG. 11, and FIG. 12 are diagrams showing an example of user information (at the time of boarding / alighting confirmation) 34b. In the user information (login time) 34 and the user information (boarding / alighting confirmation time) 34b, the login state is displayed in the login status field 132 in association with the user ID stored in the user ID field 131, and the position acquisition time is displayed. The position acquisition time is stored in column 133, the line section ID is stored in the line section ID column 134, the section is stored in the section column 135, and the boarding / alighting status is stored in the boarding / alighting status column 136.

The user ID in the user ID column 131 is an identifier that uniquely identifies a user (passenger). As described above, the user ID is also an identifier that uniquely identifies the mobile terminal device 4.
The login status of the login status column 132 is either "logged in" or "non-logged in". The boarding / alighting determination device 1 creates a "non-login" record for a user who is scheduled to log in afterwards due to pre-registration or the like, even if there is no login.
The position acquisition time in the position acquisition time column 133 is the time when the position information of the user is acquired. The position acquisition time is the login time in the user information (login time) 34, and the time in the user information (boarding / alighting confirmation time) 34b at the time of boarding / alighting confirmation.

The line section ID in the line section ID column 134 is the same as the line section ID in FIG. However, "outside the station" indicates that the user is outside the station.
The section in the section column 135 is either "station name" or "station name-station name". For example, "a station" indicates that the user is on the platform of that station. “A station to b station” indicates that the user is in a vehicle traveling from a station to b station.

The boarding / alighting status in the boarding / alighting status column 136 is either "Unknown", "Before boarding", "During boarding", or "Getting off". "Unknown" indicates that the user's operation is unknown because the user was at the station but the vehicle did not arrive at the station. “Before boarding” indicates that the user did not board the vehicle that arrived due to reasons such as a different destination. "On board" indicates that the user is on the vehicle between the station and the next station as a result of getting on the vehicle at that station. "Getting off" indicates that the user got off the vehicle at the station.

The "-" in each column of the user information 34 (34b) indicates that the login status of the record is "non-login" or the line section ID is "outside the station". Indicates that the information cannot be defined.

The position acquisition time in FIG. 9 is different for each user, such as "t01", "t02", "t03" and "t04". This is because the login time differs for each user. The position acquisition time “t1” in FIG. 10 is common to each user. This is because the boarding / alighting determination device 1 collectively acquires the position information of all users regarding the vehicle at the time when boarding / alighting is confirmed for the station a. The same applies to FIGS. 11 and 12. “T2” is the time when boarding / alighting is confirmed for station b, and “t3” is the time when boarding / alighting is confirmed for station c. Regarding the context of the time, "t01, t02, t03, t04 <t1 <t2 <t3" holds. The larger the value, the later the time. However, the context between t01, t02, t03 and t04 is not particularly limited.

Through FIGS. 9 to 12, we will look at the movement of the user P01 as an example.
-User P01 intended to pay the fare by automatic deduction from the designated account at a later date without purchasing a ticket and using a transportation IC card when boarding the vehicle from station a. User P01 walked to station a.
-At time point t01, the user P01 arrived at the platform of station a and logged in to the boarding / alighting determination device 1 from the mobile terminal device 4 (record 137 in FIG. 9). At time t01, no vehicle has arrived at the platform.

-The vehicle arrived at station a, and user P01 got on the vehicle. Shortly after the vehicle departed for the next station b, at time point t1 (t01 <t1), the tail of the vehicle reached the end of the platform. At time point t1, user P01 is between station a and station b (record 138 in FIG. 10).
-The vehicle arrived at station b, and user P01 got off the vehicle. Shortly after the vehicle departed for the next station c, at point t2 (t1 <t2), the tail of the vehicle reached the end of the platform. At time t2, user P01 is at station b (record 139 in FIG. 11).

-User P01 logged out shortly after getting off the vehicle at station b.
The vehicle arrived at station c, and other users got on and off. Shortly after the vehicle departed for the next d station, at time point t3 (t2 <t3), the tail of the vehicle reached the end of the platform. At time point t3, the boarding / alighting determination device 1 has no information about the user P01 (record 140 in FIG. 12).

(Processing procedure)
FIG. 13 is a flowchart of the processing procedure. As a premise for starting the processing procedure, it is assumed that the vehicle position information 32 (however, the latest position acquisition time column 113 and the position information column 114 are blank) is stored in the auxiliary storage device 15 in the latest state.

In step S201, the determination preparation unit 21 of the boarding / alighting determination device 1 acquires the departure time information 31 (FIG. 6). Specifically, the determination preparation unit 21 acquires the departure time information 31 from the operation management system 5. The operation management system 5 maintains the departure time information 31 in the latest state reflecting delays due to congestion and the like.

In step S202, the determination preparation unit 21 acquires the station position information 33 (FIG. 8). Specifically, the determination preparation unit 21 acquires the station position information 33 from the operation management system 5. Unless there is a new station or a station renovation, the contents of the station location information 33 will not change. Therefore, the determination preparation unit 21 may omit the step when the previously acquired station position information 33 can be used as it is.

In step S203, the determination preparation unit 21 determines whether or not the login has been accepted. Specifically, when the determination preparation unit 21 accepts a login from any of the users (step S203 “Yes”), it proceeds to step S204, and in other cases (step S203 “No”), it waits as it is. .. Here, for the sake of simplification of the explanation, it is assumed that the login is accepted from the user P01 at the station a. At this time, the mobile terminal device 4 of the user P01 transmits the user ID "P01" and the current position information to the boarding / alighting determination device 1.

In step S204, the boarding / alighting determination unit 22 of the boarding / alighting determination device 1 creates user information (at the time of login) 34 (FIG. 9). Specifically, first, the boarding / alighting determination unit 22 creates a record 137 of user information (at the time of login) 34.
Second, the boarding / alighting determination unit 22 refers to the departure time information 31 acquired in step S201, and identifies a vehicle arriving at station a immediately after the current time point t01. The vehicle identified here is referred to as the "tracked vehicle". It is assumed that the vehicle ID of the vehicle to be tracked is "01-001".

In step S205, the boarding / alighting determination unit 22 determines whether or not the departure time of the station has arrived. Specifically, the boarding / alighting determination unit 22 proceeds to step S206 when the time at the time of boarding / alighting determination at station a of the tracked vehicle arrives (step S205 “Yes”), and proceeds to other cases (step S205 “No”). ), Wait as it is.

Incidentally, the boarding / alighting determination unit 22 refers to the vehicle position information 32 (FIG. 7) and the station position information 33 (FIG. 8), acquires the departure time of the tracked vehicle at station a after departure, and obtains the departure time information 31 (departure time information 31 (FIG. 8). With reference to FIG. 6), the departure time of the tracked vehicle at station a is acquired. Then, the boarding / alighting determination unit 22 sets the time at the time of boarding / alighting determination as the time obtained by adding the departure time after departure to the departure time.

In step S206, the boarding / alighting determination unit 22 acquires the position information of the vehicle. Specifically, the boarding / alighting determination unit 22 acquires the current position information of the GPS device 42 of the tracking target vehicle.
In step S207, the boarding / alighting determination unit 22 acquires the user's position information. Specifically, the boarding / alighting determination unit 22 acquires the current position information of the GPS device 43 of the mobile terminal device 4 operated by the user P01.

In step S208, the boarding / alighting determination unit 22 compares the position information of the user with the position information of the vehicle. Specifically, first, the boarding / alighting determination unit 22 uses a circle 46 (FIG. 2) centered on the point of the position information acquired in step S206 and having the front-rear length of the tracked vehicle as the diameter, for example, an auxiliary storage device. Draw on a map (not shown) stored in advance by 15.
Secondly, the boarding / alighting determination unit 22 draws a circle 47 (FIG. 2) having a diameter “d” centered on the point of the position information acquired in step S207 on the map. The "d" here is preferably sufficiently smaller than the front-rear length of the tracked vehicle. In extreme cases, d = 0 may be set. At this time, the circle 47 becomes the point itself of the position information.

Thirdly, the boarding / alighting determination unit 22 creates a determination result of "on board" or "not on board" according to the degree of overlap between the circle 46 and the circle 47. "On board" corresponds to the boarding / alighting status "On board". "Not boarded" corresponds to the boarding / alighting status "Before boarding" or "Getting off".

The boarding / alighting determination unit 22 creates a determination result of "boarding" when the degree of overlap between the circle 46 and the circle 47 is, for example, any of the following examples, and in other cases, "boarding". Create a judgment result of "not done".
<Example 1> The circle 46 completely includes the circle 47.
<Example 2> There is an overlapping portion between the circle 46 and the circle 47.
<Example 3> The area of the overlapping portion of the circle 46 and the circle 47 exceeds a predetermined threshold value.

In step S209, the boarding / alighting determination unit 22 updates the record of the vehicle position information 32 (FIG. 7). Specifically, the boarding / alighting determination unit 22 uses the current time and the position information acquired in step S206 as the latest position acquisition time column 113 and the record for the vehicle ID “01-001” in the vehicle position information 32 (FIG. 7). It is stored in the position information field 114.

In step S210, the boarding / alighting determination unit 22 creates user information (at the time of boarding / alighting confirmation) 34b (FIG. 10). Specifically, the boarding / alighting determination unit 22 creates a record 138 of user information (at the time of boarding / alighting confirmation) 34b.

In step S211 the boarding / alighting determination unit 22 determines whether or not the logout has been accepted. Specifically, when the determination preparation unit 21 receives the logout from the user P01 (step S211 “Yes”), the determination preparation unit 21 proceeds to step S212, and in other cases (step S211 “No”), returns to step S205. In step S205 after returning, the boarding / alighting determination unit 22 determines whether or not the time at the time of boarding / alighting determination at station b has arrived.

User P01 maintains a login until getting off at the destination station. While the login is maintained, the boarding / alighting determination unit 22 repeats the processes of steps S205 to S211. Then, the boarding / alighting determination unit 22 accumulates a record of user information (at the time of boarding / alighting confirmation) 34b for the user P01 each time the tracked vehicle departs from the station.

In step S212, the boarding / alighting determination unit 22 creates a movement locus of the user. Specifically, the boarding / alighting determination unit 22 traces the boarding / alighting status of the records of the user information (at the time of login) 34 and the accumulated user information (at the time of boarding / alighting confirmation) 34b, thereby passing through the boarding station of the user P01. Get a station and get off station. After that, the processing procedure ends. In another process, the movement locus of the user is used for charging the user and the like.

In the processing procedure of FIG. 13, for the sake of clarity of explanation, an example in which one user gets on one tracking target vehicle is described. Actually, the processes of steps S203 to S212 are executed in parallel for many users. However, if multiple users log in at the same station at the same timing, the tracked trains for those users will be the same.

The above processing procedure is based on the premise that the tracked vehicle departs from each station according to the departure time information 31 acquired in step S201. In Japan, the probability that vehicles will operate on time is very high. However, the vehicle spacing may be adjusted due to congestion or the like. Therefore, when the vehicle actually departs at each station, the GPS device 42 or the train control system 6 of the vehicle 3 may transmit a "departure signal" to the effect that the vehicle has departed to the boarding / alighting determination device 1. In this case, the process of step S205 is as follows.

In step S205, the boarding / alighting determination unit 22 determines whether or not the departure signal has been received. Specifically, when the boarding / alighting determination unit 22 receives the departure signal at station a of the tracked vehicle (step S205 “Yes”), the boarding / alighting determination unit 22 waits for the departure time from the platform after departure at station a to elapse, and then proceeds to step S206. move on. In other cases (step S205 “No”), the boarding / alighting determination unit 22 stands by as it is.

(Variable example of transfer)
Especially in urban areas, many lines intersect in a complicated manner to form a network. It is often possible to transfer at a transit station. Here, "transfer" means that a user gets off a vehicle and gets on another vehicle at a certain station.

FIG. 14 is a diagram illustrating stations where transfers are possible. Line R01 has 5 stations, Line R02 has 6 stations, Line R03 has 4 stations, and Line R04 has 4 stations. doing. Of these stations, station c is shared by lines R01 and R02, and station g is shared by lines R02 and R04. Line R03 is isolated from other lines. Stations c and g are transferable stations. Note that FIG. 14 is inconsistent with the example of FIG.

(Transfer information)
FIG. 15 is a diagram showing an example of transfer information 35. The transfer information 35 is a matrix in which the vertical axis and the horizontal axis are line section IDs. The names of transferable stations in the two lines are stored in the cells at the intersections of the vertical and horizontal axes. "X" indicates that there is no transferable station on the two lines. However, "x" does not mean that the two lines are isolated from each other. For example, "x" is stored in the cell at the intersection of R01 and R04, but if the transfer is performed twice, the cell can be moved back and forth between the two.

(Takeover of tracked vehicle)
FIG. 16 is a diagram illustrating the takeover of the tracked vehicle. The thin circles in contact with each station indicate the position information of the vehicle at the time of boarding / alighting determination. The thick circle indicates the position information of the user P01. The broken line arrow is the movement locus of the user P01.

User P01 boarded a vehicle at station a on line section R01, once disembarked from that vehicle at station c, and immediately boarded another vehicle on line section R02. The circle 46x indicating the position information of the vehicle departing from the c station of the line section R01 does not overlap with the circle 47 indicating the position information of the user P01. Therefore, the boarding / alighting determination unit 22 of the boarding / alighting determination device 1 recognizes that the user P01 is not on the vehicle (bound for the d station) departing from the c station of the line section R01.

The circle 46y indicating the position information of the vehicle departing from the c station of the line section R02 overlaps the circle 47 indicating the position information of the user P01 for the first time at this point. Therefore, the boarding / alighting determination unit 22 of the boarding / alighting determination device 1 recognizes that the user P01 is on the vehicle (bound for m station) departing from the c station of the line section R02. The amount billed for the fare differs depending on whether such movement of the user P01 is determined to be a series of movement loci or two separate movement loci on the same day. Of course, the latter is more expensive for one initial ride.

(Modified example of processing procedure for taking over the vehicle to be tracked)
When the station in step S205 is a transferable station such as station c, the boarding / alighting determination unit 22 executes the following processing in step S206 immediately after that.
-The boarding / alighting determination unit 22 acquires the position information of the vehicle in the line section R01 at the time of boarding confirmation.
-The boarding / alighting determination unit 22 sets the c station of the line section 02 between the time when the vehicle of the line section R01 arrives at the c station and the time when the predetermined transfer time (for example, 15 minutes) is added to the time. At least one vehicle in the up direction and one in the down direction (transfer candidate vehicle) to be departed is specified.
-The boarding / alighting determination unit 22 acquires the position information at the time of boarding confirmation of each transfer candidate vehicle.

Further, in step S207 immediately after that, the boarding / alighting determination unit 22 acquires the position information of the user P01 at the time when the boarding of each transfer candidate vehicle is confirmed.

Further, in step S208 immediately after that, the boarding / alighting determination unit 22 executes the following processing.
-The boarding / alighting determination unit 22 determines the degree of overlap between the position information of the user P01 and the position information of all the transfer candidate vehicles.
-If there is a transfer candidate vehicle whose position information overlaps with the position information of the user P01, the boarding / alighting determination unit 22 identifies the vehicle as the vehicle actually boarded (transferred) by the user P01. To do. If there are no overlapping vehicles, the user P01 determines that the vehicle has disembarked without changing trains.

(How to get location information)
In addition to GPS, there is an example of using an image acquired by a camera mounted on the vehicle as an example of acquiring the position information of the vehicle. The camera can capture the background (including the sign with the station name) from the car window. In addition to GPS, as an example of acquiring the position information of the user, there is an example in which the mobile terminal device 4 uses the position information of the wireless base station 7 for which communication has been established.
