Description

  The present invention relates to a moving means determining device, a moving means determining method, and a program.

  In recent years, many mobile terminals have a GPS (Global Positioning System) function. Conducting behavior analysis using data obtained by using the GPS function has been studied (see Patent Document 1). By using the GPS function, it is possible to perform a behavior analysis with higher accuracy than a conventional questionnaire survey. For example, it is possible to estimate the place of stay of the tourist and to determine the means of transportation used by the tourist.

  In Patent Literature 1, a moving means is determined by comparing a speed between measured values with a predetermined threshold value in a moving trajectory recorded by GPS or the like.

JP 2003-242169 A

  In the method of Patent Document 1, since the speed between the measured values is compared with a predetermined threshold, the train or the bus stops at the station or the stop even when actually riding the train or the bus. As a result, there is a possibility that the moving means is erroneously determined to be on foot because the speed is lower than the threshold value.

  Further, an error may occur in the positioning data depending on the position of the GPS satellite, the environment of the surveyed site, and the like, and the speed as the determination criterion may not be accurately calculated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In the embodiment of the present invention, a description will be given of a moving means determination device that determines a moving means of a behavior investigation subject. The moving means determination device is a device that measures and records the movement trajectory of the behavior investigation target using GPS, a beacon, Wi-Fi (Wireless Fidelity), or the like, and determines the movement method of the behavior investigation target from the movement trajectory. The travel mode determination device uses the travel route and travel speed in the travel trajectory of the behavior survey target, the time constraints of the timetable of the transportation system in the target area, and the spatial constraints of the route map to determine the positioning error. Is determined in a robust manner.

  Terms used in the embodiments of the present invention are defined as follows.

  The positioning point is data including the position coordinates and the positioning time of the behavior survey target measured by the terminal possessed by the behavior survey target using GPS, beacon, Wi-Fi, or the like.

  The movement trajectory is a set of positioning points extracted in a period specified for each behavior investigation target person.

  A stop is a place where passengers get on and off such as a railway station and a bus stop.

  The route is a predetermined operation route such as a railway or a bus.

  A segment is a set of time-series continuous positioning points on the same route.

  The route type is a moving means determined by the moving means determination device, and in the embodiment of the present invention, it is assumed that a railway, a bus, or a foot is the moving means.

  FIG. 1 is a functional block diagram of a moving means determination device 100 according to an embodiment of the present invention. The travel mode determination device 100 includes a positioning point information storage section 101 as a storage section capable of storing information such as a database, a route geographic information storage section 103, a travel mode determination reference table storage section 105, a route timetable, And an information storage unit 107. Further, the moving means determination device 100 includes a nearby route search unit 111 as a functional unit capable of performing information processing, a moving means determination unit 113, and a determination result output unit 115.

  FIG. 2 is a diagram illustrating an example of information stored in the positioning point information storage unit 101. The positioning point information accumulating unit 101 accumulates a movement trajectory that is a set of positioning points including the position coordinates and the positioning time measured by the terminal of the behavior investigation target person. For example, the positioning point information accumulating unit 101 accumulates the ID of the behavior investigation target person, positioning coordinates (latitude and longitude), and positioning time. As described below, a candidate route route in the vicinity of the behavior research target is determined from the relationship between a set of positioning points, which are movement trajectories, and spatial constraints on the route, and the candidate route route is determined by the positioning point information. It is stored in the storage unit 101. When there is no candidate route route near the behavior investigation target, information indicating that the route is outside the route or on foot is stored in the positioning point information storage unit 101.

  FIG. 3 is a diagram illustrating an example of information stored in the route geographic information storage unit 103. The route geographic information storage unit 103 stores route routes of transportation means such as buses and railways as a set of position coordinates. For example, the route geographic information storage unit 103 stores a route name, a route type (railway or bus), a location type (section or stop), and a latitude / longitude at a certain position on the route.

  FIG. 4 is a diagram illustrating an example of information stored in the moving means determination reference table storage unit 105. The moving means determination criterion table storage unit 105 stores a value serving as a reference for determining the moving means. For example, the moving means determination reference table storage unit 105 stores a determination speed upper limit value and a determination speed lower limit value for each route type. In the example illustrated in FIG. 4, when moving at a moving speed between the lower limit of the determination speed of 10 km / h and the upper limit of the determination speed of 120 km / h, there is a high possibility that the railway is used. Indicates that The determination speed upper limit value and the determination speed lower limit value may be obtained by, for example, measuring the distribution of the average speed for each route type, and the fixed average for each route type stored in the route timetable information storage unit 107. It may be obtained from the speed. As a result, in the following embodiment, a threshold for classifying a walk or other railway or bus is set to 10 km / h. Also, a threshold for classifying railways and buses is set to 20 km / h. The threshold values (10 km / h and 20 km / h) set in this manner may also be stored in the moving means determination reference table storage unit 105.

  The route timetable information storage unit 107 stores a timetable for each route (not shown). For example, the route timetable information accumulation unit 107 accumulates information included in a normal timetable, such as a route name, a stop, and a departure time.

  The nearby route search unit 111 acquires the movement trajectory of the behavior investigation target from the positioning point information storage unit 101, and the movement trajectory acquired in a predetermined range exists in the route route of the route geographic information storage unit 103. In this case, it is determined that the route is a candidate route. The route type and the route name of the candidate route route are associated with the movement locus in the positioning point information storage unit 101. When there are a plurality of candidate route routes, the route type and the route name of the plurality of candidate route routes are associated with the movement locus in the positioning point information storage unit 101. When there is no route route in the vicinity, the route type of outside the route or walking is associated with the movement locus in the positioning point information storage unit 101.

  FIG. 5 shows an example in which the nearby route search unit 111 determines the route as a candidate route. Here, a range within 50 m from the stop is defined as a stop (in a railway station or a bus stop), and a range within 50 m from a route route is defined as between stops (between railway stations or between bus stops). The nearby route search unit 111 can determine whether the movement trajectory of the behavior investigation target person exists within the stop or between the stops. When the movement locus moves between the stops, the route route is determined to be a candidate route route. At this time, a positioning error may be considered. Examples of the positioning error will be described below.

In order to determine the distance to the candidate route route, the nearby route search unit 111 determines the latitude and longitude of the positioning points stored in the positioning point information storage unit 101 and the latitude and longitude of the route route stored in the route geographic information storage unit 103. longitude is calculated as follows distance D _i between the stop field or line route and positioning point.

D _i = (d _i + d _{i + 1} ) / 2
Here, _Di is the distance [m] between any positioning point i and the stop or route route, and _di and di _{+ 1} are the distances between any of the positioning points i and i + 1 and the stop or route route. Distance [m]. Incidentally, as shown in FIG. 6, if there is a vertical line between the end points of the line route (stop field), d _i and d _{i + 1} is the length of the perpendicular line to the line route (distance), and the end point of the route Route (retention If there is no vertical line between play), d _i and d _{i + 1} is the distance to the nearest vertex of the line route.

In the following description, the distance _{D i} determined for the train station and _{D station,} the distance _{D i} determined for railway routes and _{D rail,} the distance _{D i} determined for bus stop D and _busstop, the distance _{D i} determined for bus routes and _{D busroute.}

  As shown in FIG. 7, even if the vehicle is within 50 m from the stop and the route route, it is not determined as a candidate route route when it is considered that the vehicle has returned to the same stop (railway station or bus stop).

As shown in FIG. 8, in consideration of the positioning error at the stop, for example, when the sum of the elapsed times of the positioning points existing outside the 50 m area of the stop is less than θ _s (s), Assume it was present. As a result, when the movement locus exists within a range of 50 m from the route route, it is determined to be a candidate route route. For example, θ _s is set to be three times the average acquisition interval of the positioning points included in the target stop section and the preceding and following stop sections.

As shown in FIG. 9, in consideration of the positioning error in the route, for example, when the sum of the elapsed times of the positioning points existing outside the 50 m range of the route route is less than θ _s (s), the route is determined to be the candidate route route. I do.

  As shown in FIG. 10, even if a positioning error is considered, if there is no positioning point in the stop, it is not determined as a candidate route route.

  As shown in FIG. 11, even if the positioning error is considered, if there is no positioning point in a certain stop in the route route and there is a positioning point outside the stop, it is not determined as a candidate route route.

  The moving means determination unit 113 calculates a moving speed calculated from the moving trajectory, and determines the moving means of the behavior investigation target person based on the calculated moving speed. When there is a candidate route route, the moving means determination unit 113 calculates the moving speed from the movement trajectory in the candidate route route, and based on the calculated moving speed, the behavior investigation target person uses the moving means of the candidate route route. It is determined whether the vehicle is moving (in the case where there are a plurality of candidate route routes, which moving means is used) and whether the vehicle is moving on foot.

  Hereinafter, the moving means determination algorithm in the moving means determination unit 113 will be described in detail with reference to FIGS.

  The moving means determination unit 113 determines that the movement trajectory of the behavior investigation target does not exist on the route route between the railway stations in the nearby route search unit 111 (S101: NO), and the movement trajectory of the behavior investigation target is between the bus stops. (S103: YES), it is determined that the transportation means is bw (bus or on foot) (S105). In addition, the moving means determination unit 113 determines that the movement trajectory of the behavior investigation target does not exist in the route route between the railway stations in the nearby route search unit 111 (S101: NO), and the behavior trajectory of the behavior investigation target is a bus. If it does not exist on the route route between the stops (S103: NO), it is determined that the transportation means is tbw2 (any of railway, bus, and foot) (S107). Here, the reason for determining that the means of transportation is tbw2 without deciding that it is walking is that the person to be investigated is waiting for a railroad or a bus at a stop (railroad station or bus stop), which is the end point of the segment, and then performing positioning. This is for accurately determining a moving means when a point has not been acquired.

  In addition, the moving means determination unit 113 determines that the movement trajectory of the behavior investigation target exists in the route route between the railway stations in the nearby route search unit 111 (S101: YES), and the movement trajectory of the behavior investigation target is a bus stop. If it is present on the route route between the two (S109: YES), it is determined that the transportation means is tbw1 (any one of railway, bus, and foot) (S111). In addition, the moving means determination unit 113 determines that the movement trajectory of the behavior investigation target exists in the route route between the railway stations in the nearby route search unit 111 (S101: YES), and the movement trajectory of the behavior investigation target is a bus stop. If the route does not exist (S109: NO), it is determined that the moving means is tw (railway or foot) (S113).

  If the moving means is tbw1 (S111), the moving means determination unit 113 determines the moving means in advance based on the threshold (10 km / h and 20 km / h) for determining the moving means and the moving speed in the candidate route route. Then, the means of movement of the behavior survey subject is determined.

The average traveling speed V _ave between the positioning points included in the section of the candidate route route can be calculated as follows.

V _ave = ΣV _i / n
However, V _ave is the candidate average speed of all the positioning points included in the route route interval [km / h], V _i is at a rate between positioning points included in the interval candidate routes route [km / h] , N is the total number of positioning points included in the section of the candidate route route.

If the average moving speed V _ave is equal to or higher than 20 km / h (S115: YES), the moving means determination unit 113 determines that the moving means is t (railroad) (S117). If the average moving speed V _ave is 10 km / h or more and less than 20 km / h (S115: NO, S119: YES), it is determined that the moving means is tb (railroad or bus) (S121). If the average moving speed V _ave is less than 10 km / h (S115: NO, S119: NO), it is determined that the moving means is bw (bus or foot) (S123).

  In the case where the moving means is tw (S113), the moving means determination unit 113 also determines the moving means on the basis of the previously calculated threshold (10 km / h) for determining the moving means and the moving speed in the candidate route route. Then, the means of movement of the behavior survey target person is determined.

If the average moving speed V _ave is equal to or greater than 10 km / h (S125: YES), the moving means determination unit 113 determines that the moving means is t (railroad) (S127). If the average moving speed V _ave is less than 10 km / h (S125: NO), it is determined that the moving means is w (walk) (S129).

  Next, a distinction between a bus and a walk will be described with reference to FIG.

  In the case of a bus, there are a section where the moving speed of the bus is slow and a section where the moving speed of the bus is fast depending on the location between the bus stops. Whether the moving speed of the bus is slow or fast is determined by acquiring the timetable of the candidate route route from the route timetable information storage unit 107, and selecting the section in the candidate route route where the behavior research target exists. If the scheduled speed of the bus is lower than the scheduled average speed of all sections, it is considered that the bus traveling speed is slow, and the scheduled speed of the section where the behavior survey target exists on the candidate route route is If the speed is faster than the average speed, it is regarded as a section where the moving speed of the bus is fast.

  Specifically, the set speed ATV of the section in which the behavior survey target exists on the candidate route route can be calculated as follows.

ATV = (L × 60) / (T _table × 1000)
Here, ATV is a specified speed [km / h] between the bus stops, L is a distance [m] between the bus stops, and T _table is a required time [minutes] between the bus stops in the timetable.

  The average speed of all sections

とすると、ＡＴＶが

Then, ATV

以上である場合（Ｓ２０１：ＹＥＳ）、すなわち、バスの移動速度が速い区間では、移動手段がｂｗ１（バス又は徒歩）であると判定する（Ｓ２０３）。また、ＡＴＶが

If this is the case (S201: YES), that is, in a section where the moving speed of the bus is high, it is determined that the moving means is bw1 (bus or walking) (S203). Also, ATV

未満である場合（Ｓ２０１：ＮＯ）、すなわち、バスの移動速度が遅い区間では、移動手段がｂｗ２（バス又は徒歩）であると判定する（Ｓ２０５）。

If it is less than (S201: NO), that is, in a section where the moving speed of the bus is slow, it is determined that the moving means is bw2 (bus or walking) (S205).

When the moving means is bw1 (S203), if the average moving speed V _ave is 10 km / h or more (S207: YES), it is determined that the moving means is b (bus) (S209), and the average moving speed V _{ave is used.} Is less than 10 km / h, it is determined that the moving means is w (on foot) (S211).

  When the moving means is bw2 (S205), a threshold (10 km / h) for determining the moving means is multiplied by a coefficient as a threshold for classifying the bus and walking, and the moving means of the behavior survey person is Judge whether it is a bus or a walk. ATV

未満である場合、バスと徒歩を分類するための以下の閾値Ｖ'を定義する。

If less than, define the following threshold V 'for classifying buses and walking.

ただし、Ｖ'は平均速度閾値［ｋｍ／ｈ］であり、ＡＴＶは表定速度［ｋｍ／ｈ］であり、

Here, V ′ is an average speed threshold [km / h], ATV is a specified speed [km / h],

は全区間の平均表定速度［ｋｍ／ｈ］である。

Is the average set speed [km / h] of all sections.

At this time, if the average moving speed V _ave is equal to or higher than V'km / h (S213: YES), it is determined that the moving means is b (bus) (S215), and the average moving speed V _ave is V'km / h. If it is less than h (S213: NO), it is determined that the moving means is w (foot) (S217).

  Next, the distinction between a train and a bus will be described with reference to FIG.

  If the moving means is tb, that is, if the candidate route route includes the railway route and the bus route route, the moving means determination unit 113 determines the moving means based on the distance from the movement track to the candidate route route.

  At this time,

であれば（Ｓ３０１：ＹＥＳ）、移動手段がｔ（電車）であると判定する（Ｓ３０３）。

If it is (S301: YES), it is determined that the moving means is t (train) (S303).

であれば（Ｓ３０１：ＮＯ）、移動手段がｂ（バス）であると判定する（Ｓ３０５）。

If it is (S301: NO), it is determined that the moving means is b (bus) (S305).

  Next, with reference to FIG. 15, a description will be given of the determination of the moving means including the segment end points.

  When it is determined that the transportation means is t (train) or tbw2 (any of railway, bus, and foot), it is determined whether the end point of the segment is within 50 m from the railway station. When it is within 50 m from the railway station (S401: YES), it is determined that the moving means including the moving means at the end point of the segment is a train (S403).

  If the end point of the segment is not within 50 m of the railway station (S401: NO), or if the transportation means is b (bus), it is determined whether the end point of the segment is within 50 m of the bus stop. When it is within 50 m from the bus stop (S405: YES), it is determined that the moving means is a bus including the moving means at the end point of the segment (S407).

  When the end point of the segment is not within 50 m of the railway station and the bus stop (S401: NO, S405: NO), or when the moving means is w (on foot), the moving means including the moving means at the end point of the segment is on foot. Is determined (S409).

  In addition, in order to more accurately determine whether or not the moving means is on foot, data of an accelerometer provided in the terminal of the behavior investigation subject may be used. The moving means determination unit 113 estimates the possibility that the moving means is on foot by detecting vertical movements at regular intervals with an accelerometer, and the moving means is a moving means (train or bus) on the candidate route route. Or on foot. For example, when it is determined from the data of the accelerometer that the moving means is likely to be on foot, a threshold (10 km / h) for determining the moving means is set so that the possibility of being determined to be on foot is increased. And V ′) may be changed. For example, when the possibility of walking is higher than the predetermined probability due to the data of the accelerometer, the threshold value 10 km / h used in S119 and S125 of FIG. 12 may be increased. Similarly, when the possibility of walking is higher than the predetermined probability according to the data of the accelerometer, the threshold value for distinguishing between a bus and walking may be increased to 10 km / h in S207 of FIG. Similarly, when the possibility of walking is higher than a predetermined probability according to the data of the accelerometer, the threshold value V ′ for distinguishing between a bus and walking may be increased in S213 in FIG.

  The determination result output unit 115 outputs the result determined by the moving means determination unit 113.
