Secretariat of the Central Kyoto Metropolitan City Transportation Planning Council, “About the 4th Central Kyoto City Person Trip Survey (Interim Report)”, [online], [Search September 24, 2003], Internet <URL: http : //www.chukyo-pt.gr.jp/index.html> Ryuichi Mato et al. "Start / End Traffic Measurement System" Matsushita Technical Journal Vol.44 No.3 Jun.1998

However, the person trip survey requires a great deal of labor and time, so it cannot be done frequently, and has been conducted only once every few years. For this reason, there has been a demand for an apparatus and method that can acquire the same result as the person trip survey without using a questionnaire or the like.
In addition, since the OD traffic volume calculation device can only calculate the OD traffic volume of an automobile, there is an apparatus / method that can calculate the OD traffic volume for each moving means such as railroad, automobile, bicycle, and walking. It was desired.

  According to the present invention, the speed when the owner of the mobile terminal moves from O to D is calculated based on the position information acquired from the mobile terminal, and the owner of the mobile terminal is calculated based on the calculated speed. It is possible to determine which moving means is used for movement. Therefore, since it is possible to grasp from where to where and by what means of movement without carrying out distribution / collection work or the like of the questionnaire paper, the labor and time required for the investigation can be greatly reduced.

In addition, as labor and time are reduced, the same effects as the person trip survey can be achieved over a long period of time, which can greatly contribute to grasping and analyzing detailed traffic conditions.
The invention according to claim 2 is characterized in that the determining means determines which moving means has been used based on the maximum moving speed calculated by the calculating means.

  According to the present invention, it is possible to determine which moving means is based on the maximum moving speed calculated by the calculating means. The maximum moving speed for each moving means is unique for each car, bicycle, railway, etc., and the speed of each other is different, so the moving means is calculated using the maximum moving speed calculated by the calculating means. By performing the determination, it is possible to improve the reliability of the information of the moving means to be determined.

  According to a third aspect of the present invention, the moving means discriminating apparatus includes a change pattern storage means for storing a change pattern of the moving speed of the moving means, and the discriminating means is a moving means stored in the change pattern storage means. It is characterized by determining which moving means is used for movement based on the change pattern of the moving speed and the change pattern created from the moving speed calculated by the calculating means.

According to a fourth aspect of the present invention, the moving means discriminating apparatus includes a map data storing means for storing map data, and the discriminating means is position information relating to a moving route in the map data stored in the map data storing means. On the basis of the position information acquired by the acquisition means, it is determined what kind of movement means is used for movement.
According to the present invention, map data is stored in advance, and it is possible to determine what kind of moving means is based on the position information regarding the moving route in the map data and the position information acquired by the acquiring means. . When the acquired position information is on the moving route, the moving means used by the holder of the mobile terminal can be specified according to the moving route. For example, if the location information is on a track, the owner of the mobile terminal can be identified as using the railway, and if the location information is on the road, the owner of the mobile device uses a car. Can be identified. By determining the moving means in consideration of this specification, the reliability of the information of the moving means to be determined can be improved.

As described in claims 2 to 4, when determining which moving means the holder of the mobile terminal has moved based on the position information acquired by the acquiring means, there are various By discriminating based on a simple viewpoint, it is possible to increase the reliability of the information of the moving means to be discriminated and greatly contribute to grasping and analyzing the actual state of traffic.
According to a fifth aspect of the present invention, when the position information acquired by the acquisition means is the same position for a predetermined time period Tod or longer, the calculation means sets the position as O or D of the owner of the portable terminal. It is characterized by that.

When the fixed time Tod is, for example, several hours, it is natural that the owner of the mobile terminal thinks that he / she stays at the fixed point without moving by the moving means. OD information of the owner of the mobile terminal can be acquired by setting the point not using this moving means as O or D of the trip.
According to a sixth aspect of the present invention, the calculation means is configured such that the position information acquired by the acquisition means is the same position for a predetermined time Tstop or more while the owner of the mobile terminal moves from O to D. The position is set as the stop position of the holder of the portable terminal, and the speed is calculated for each stop position.

  If the fixed time Tstop is, for example, several minutes, it is considered that the moving means used by the owner of the mobile terminal is stopped. Tstop has a shorter stop time than Tod. Therefore, by introducing the concept of the stop position into the position information acquired from the mobile terminal, it is possible to know in detail from the position information acquired by the acquiring means to the state of the moving means used by the mobile terminal holder.

The invention according to claim 7 is characterized in that the calculating means calculates, as the connecting position, a stop position where the front and rear moving means are replaced (different) at each stop position.
According to the present invention, the stop position in which the moving means at the front and rear are replaced among the stop positions can be set as the transit position. If the moving means are different at a certain time Tstop, it is considered that the owner of the mobile terminal has changed the moving means such as changing from walking to railway. Therefore, by introducing the concept of transit position to the information acquired from the mobile terminal, the mobile terminal holder used it even when multiple moving means were included while moving from O to D Since each moving means can be distinguished, it can greatly contribute to grasping and analyzing the actual state of traffic.

As described above, by using the moving means discriminating apparatus according to claims 1 to 7, the moving means can be automatically discriminated using a portable terminal such as a mobile phone, PHS, or PDA. In other words, the same effect as the person trip survey can be achieved.
In addition, by determining the means of transportation based on information obtained from a mobile terminal based on various viewpoints, it is possible to increase the reliability of the identified means of transportation and greatly contribute to the understanding and analysis of traffic conditions. it can.

The invention according to claim 8 is the speed when the position information is acquired from the mobile terminal, and the owner of the mobile terminal moves from O (departure point) to D (destination) based on the acquired position information. The moving means discriminating method is characterized in that, based on the calculated speed, it is discriminated which moving means the holder of the portable terminal has moved.
According to the present invention, an effect similar to that of the first aspect can be achieved.

Based on the calculated speed, it is determined which moving means the owner of the portable terminal has moved, and the OD traffic volume for each moving means determined by the determining means is determined. It is an OD traffic volume calculation method characterized by calculating.

  According to the present invention, the same effect as that of the ninth aspect can be achieved.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram showing a system to which a moving means discriminating apparatus and an OD traffic amount calculating apparatus according to an embodiment of the present invention are applied.
In this system, radio base stations 11a to 11c (hereinafter, collectively referred to as “radio base station 11”) for acquiring position information of the mobile terminal 12 and the mobile terminal 13 with GPS (Global Positioning System). ), The monitoring control device 10 for monitoring and controlling the radio base station 11, the moving means discriminating apparatus 1 for determining the moving means from the acquired position information, and calculating the OD traffic volume, and the OD traffic volume The calculation device 2 is included.

  Each radio base station 11 cooperates with other radio base stations, based on a recognition code such as a telephone number acquired from the mobile terminal 12 and a reception time difference thereof, and positional information (latitude, longitude, altitude) of the mobile terminal 12. Etc.) can be calculated. Further, the moving speed of the holder of the GPS-equipped mobile terminal 13 can also be calculated based on the position information acquired from the GPS-equipped mobile terminal 13 (see JP-A-7-38951). Hereinafter, the portable terminal 12 and the GPS-equipped portable terminal 13 are collectively referred to as a “portable terminal”.

  The moving means discriminating device 1 discriminates the moving means from the position information management section 7 for managing the acquired position information, the position information storage section 3 for storing the position information, and the acquired position information. When the moving means discriminating section 8 for creating the OD information, the map data storage section 4 for storing the map data referred to when the moving means is discriminated, and the moving means are discriminated. A change pattern storage unit 6 for storing a change pattern of the moving speed of the moving unit referred to in FIG. 5; an OD information storage unit 5 for storing the OD information created by the moving unit determination unit 8; Is provided.

The location information of the mobile terminal acquired by each radio base station 11 is stored in the location information storage unit 3 via the monitoring control device 10 and the location information management unit 7.
The OD traffic volume calculation device 2 includes an OD traffic volume calculation unit 9 for calculating the OD traffic volume from the OD information created by the moving means determination unit 8.
FIG. 2 is a flowchart for explaining the control operation of the moving means discriminating apparatus 1.

The position information management unit 7 extracts the position information of the same recognition code from the position information stored in the position information storage unit 3 at regular intervals such as one day, one week, or one month. Step S1).
An example of the extracted position information is shown in FIG. In this example, the position information of the GPS mobile terminal 13 with the identification code “12A8G329X” is extracted. A recognition code is transmitted every 15 seconds from the mobile terminal 13 with GPS having the identification code “12A8G329X” to each wireless base station 11, and the position information calculated based on this recognition code is updated every 15 seconds. Is stored in the position information storage unit 3. This position information is composed of latitude, longitude, altitude, speed and direction.

Referring to FIG. 2 again, when the position information of the portable terminal having the same recognition code is extracted, not all the position information stored in the position information storage unit 3 has been extracted (NO in step S2). The extracted position information is arranged in order of time, and it is determined whether or not the position information at the same position has been continuously detected for a predetermined time _Tod , for example, several hours or more. And when it is detected continuously more than _Tod , the same position is regarded as the position where the trip of the portable terminal holder was interrupted, and the position is D (destination) of the previous trip or the subsequent trip. Is calculated as O (departure point) (step S3).

When position information at the same position is continuously detected for several hours or more, it is considered that the holder of the portable terminal stays at a certain point without moving by the moving means. For this reason, the OD information of the owner of the portable terminal can be acquired by setting the position that has not moved to D of the previous trip or O of the subsequent trip.
In consideration of the fact that the position information acquired from the mobile terminal includes an error, when position information of the same position is detected continuously for more than _Tod , the position is set to D of the previous trip, Or, not only in the configuration to calculate as O of the subsequent trip, but when the position information of the position within a certain range is continuously detected for more than _Tod , the average value or median value of those positions is obtained from the previous trip. It may be configured to calculate D or O of subsequent trips.

Then, while the holder of the portable terminal moves from O to D, it is determined whether or not the position information at the same position has been continuously detected for a predetermined time T _stop , for example, several minutes. And when it is detected continuously for T _stop or more, the same position is regarded as a position where the moving means used by the portable terminal holder is stopped, and is calculated as a stop position M during the trip. (Step S4).

When the information acquired is the same for several minutes while the holder of the portable terminal moves from O to D, it is considered that the moving means used by the portable terminal holder is stopped. Therefore, by introducing the concept of the stop position and processing the position information acquired from the mobile terminal, it is possible to know in detail the state of the moving means used by the mobile terminal holder.
In consideration of the fact that the position information acquired from the mobile terminal includes an error, when position information T _{stop at} the same position is continuously detected, the position is calculated as the stop position M. However, the present invention is not limited to this, and it may be configured to calculate an average value or median value of the positions as the stop position M when position information of positions within a certain range is continuously detected.

  When the trip O and D and the stop position M are calculated, the differential for the respective positions between the stop positions of O and the stop position M, the stop position M and the stop position M, and the stop positions M and D is performed. As a result, the speed between the respective stop positions is calculated (step S5). The speed in the position information of the GPS mobile terminal 13 calculated by the radio base station 11 may be used without performing this differentiation process.

FIG. 4 is a graph schematically showing the speeds between the O and M, M and M, and M and D stop positions calculated from the position information of FIG.
Referring to FIG. 4, in this figure, the above-described trips O and D and stop positions M1 to M9 are entered. The speeds between the stop positions of O and M, M and M, and M and D are depicted as time relationships.

Referring to FIG. 2 again, when the speed between the respective stop positions is calculated, it is determined based on this speed what moving means the mobile terminal holder has moved (step S6). .
The moving means discriminating process is performed by the moving means discriminating unit 8, and the moving means discriminating unit 8 moves the map data stored in the map data storage unit 4 and the moving unit stored in the change pattern storage unit 6. The moving means is determined based on the change pattern of the moving speed for each.

The map data stored in the map data storage unit 4 includes a position on a map of a railway such as a railroad, a position on a map of a motorway such as a highway, and a map of a bicycle road such as a cycling road. The position, the position on the map of a pedestrian road such as pedestrian heaven, the position on the map of a general road, and the like are included.
The change pattern of the moving speed of the moving means stored in the change pattern storage unit 6 includes a change pattern of the moving speed of the railway, a change pattern of the moving speed of the automobile, a change pattern of the moving speed of the bicycle, and a moving speed of the pedestrian. The change pattern is included.

  The change pattern of the moving speed of each moving means includes a speed unit composed of an acceleration when the moving means accelerates, a constant speed when the moving means is constant speed, and a deceleration time when the moving means decelerates. . Some movement speed change patterns include three or more speed units. Each acceleration time, each constant speed time, and each deceleration time are different from each other. A specific example of the change pattern of the moving speed of each moving means is as follows.

The change pattern of the moving speed of the railway is composed of three or less speed units. Furthermore, the average acceleration during each acceleration is 4 to 6 m / s ² , each acceleration time is 20 seconds or more, and each constant speed time is 30 seconds or more. Moreover, the average deceleration at each deceleration is 3 to 5 m / s ² , and each deceleration time is 40 seconds or more.
The change pattern of the moving speed of the automobile includes a plurality of speed units. Furthermore, the average acceleration at each acceleration is ² to 4 m / s ² , and the average deceleration at each deceleration is 1 to 3 m / s ² .

The change pattern of the moving speed of the bicycle includes a plurality of speed units. Furthermore, the average acceleration at each acceleration is 0 to ² m / s ² , and the average deceleration at each deceleration is 0 to 1 m / s ² .
The change pattern of the walking movement speed does not exist at the time of acceleration and deceleration, and is configured only at the constant speed.

FIG. 5 is a diagram illustrating a logical expression for explaining an example of the determination process of the moving unit.
Referring to FIG. 5, when the moving means determination process is started, first, the maximum moving speed between the respective stop positions is obtained. At this time, if the maximum movement speed is 0 km / h to 5 km / h, the logical signal V1 is obtained. If the maximum movement speed is 5 km / h to 15 km / h, the logical signal V2 is provided, and the maximum movement speed is 15 km / h to 60 km. If / h, the logic signal V3 is turned on, and if the maximum moving speed is 60 km / h to 100 km / h, the logic signal V4 is turned on.

  In general, the maximum movement speed for walking is 0 km / h to 5 km / h, the maximum movement speed for bicycles is about 5 km / h to 15 km / h, and the maximum movement speed for cars is 15 km / h to 60 km / h. On the other hand, the maximum travel speed of the railway is 60km / h to 100km / h. Thus, the maximum moving speed of the moving means is unique to each other and is different from each other. Therefore, by determining the moving means based on the maximum moving speed between the respective stop positions, it is possible to improve the reliability of the information of the moving means determined.

  And each position of the portable terminal between each stop position and each position on the movement route of the map data stored in the map data storage unit 4 are compared, and where the portable terminal is located. You are asked if you are. If the portable terminal is located on the track, the logical signal L1 is obtained. If the portable terminal is located on the road for exclusive use of the automobile, the logical signal L2 is obtained. If the portable terminal is located on the road for exclusive use of the bicycle, the logical signal L3 is obtained. However, if the mobile terminal is located on a pedestrian road, the logical signal L4 is turned on, and if the mobile terminal is located on a general road, the logical signal L5 is turned on. Here, the mobile terminal is located on the map data track or on the road. However, in consideration of the fact that the position information acquired from the mobile terminal includes an error, the mobile terminal The logic signals L1 to L5 may be turned on when the vehicle is located near the road.

For example, in the map data, when the mobile terminal is located on an automobile-only road, it can be determined that the mobile terminal holder is moving by car. Thus, by determining the moving means while referring to the position information of the mobile terminal and the position information regarding the moving route in the map data, the reliability of the information of the moving means to be determined can be improved.
Next, it is determined which movement means change pattern stored in the change pattern storage unit 6 is similar to the change pattern of the movement speed between the stop positions. For example, the change pattern of the moving speed is composed of 3 or less speed units, the average acceleration at each acceleration is 4-6 m / s ² , and each acceleration time is 20 seconds or more. If the constant velocity time is 30 seconds or more, the average deceleration at each deceleration is 3 to 5 m / s ² and each deceleration time is 40 seconds or more, the change pattern of the moving speed is It is determined that the pattern is similar to the railway change pattern, and the logic signal P1 is turned on.

Similarly, this is a moving speed change pattern including a plurality of speed units, the average acceleration at each acceleration is ² to 4 m / s ² , and the average deceleration at each deceleration is all 1 If it is ˜3 m / s ^2, it is determined that the change pattern of the moving speed is similar to the change pattern of the automobile, and the logic signal P2 is turned on.
Further, the movement speed change pattern includes a plurality of speed units, and the average acceleration at each acceleration is all 0-2 m / s ² and the average deceleration at each deceleration is all 0-1 m / s. if it is s ^2, the change pattern of the moving speed is determined to be similar to bicycle change pattern, a logic signal P3 is turned on.

In addition, when the change pattern of the moving speed is always constant, the change pattern is determined to be similar to the walking change pattern, and the logic signal P4 is turned on.
The change pattern of the moving speed for each moving means is unique and the change pattern is different from each other. Therefore, the determination is made by determining whether or not the change pattern of the movement speed between the stop positions is similar to the change pattern of the movement speed for each moving means stored in each change pattern storage unit 6. The reliability of the information of the moving means used can be improved.

  When each logic signal is obtained, the moving means is determined based on these signals. When the logic signal of the maximum movement speed is V3 or V4, the logic signal of the map data is L1, and the logic signal of the change pattern of the movement speed is P1, the owner of the mobile terminal is on the railroad (See FIG. 5A). Further, when the logic signal of the maximum movement speed is any one of V1 to V4, the logic signal of the map data is L2 or L5, and the logic signal of the change pattern of the movement speed is P2, the possession of the portable terminal It is determined that the person is in a car (see FIG. 5B).

  When the logic signal of the maximum movement speed is V1 or V2, the logic signal of the map data is L3 or L5, and the logic signal of the change pattern of the movement speed is P3, the owner of the mobile terminal rides a bicycle. (See FIG. 5C). When the logic signal of the maximum movement speed is V1, the logic signal of the map data is L4 or L5, and the logic signal of the change pattern of the movement speed is P4, the portable terminal holder moves on foot. (See FIG. 5D).

  Therefore, the maximum movement speed between each stop position is any of 15 km / h to 60 km / h, and the mobile terminal is located on the map data track, and the movement speed change pattern is Only when it is similar to the change pattern, it is determined that the owner of the mobile terminal is using the railway. In addition, the maximum movement speed between each stop position is any of 15 km / h to 60 km / h, and the mobile terminal is located on a road dedicated to automobiles or a general road of map data, and the movement speed Only when the change pattern is similar to the change pattern of the car, the holder of the mobile terminal determines that the car is being used.

  Furthermore, the maximum moving speed between each stop position is in the range of 0 km / h to 15 km / h, and the mobile terminal is located on a bicycle road or a general road of map data, and the moving speed Only when the change pattern is similar to the change pattern of the bicycle, it is determined that the owner of the mobile terminal is using the bicycle. In addition, the maximum movement speed between each stop position is any of 0 km / h to 5 km / h, and the mobile terminal is located on the pedestrian road or the general road of the map data, and Only when the change pattern of the moving speed is similar to the change pattern of the pedestrian, it is determined that the owner of the mobile terminal is using a car.

In this way, when determining what moving means the holder of the mobile terminal has moved based on the position information between the respective stop positions, the maximum moving speed, map data, and movement between the respective stop positions are determined. By performing discrimination based on the three viewpoints of the speed change pattern, the reliability of the discriminated information can be improved, which can greatly contribute to grasping and analyzing the actual state of traffic.
Referring to FIG. 2 again, when the moving means is determined, the connecting position N is calculated (step S7). The transfer position N is a stop position M in which the front and rear moving means are different.

  If the moving means are different after a lapse of a certain time Tstop for several minutes, it is considered that the holder of the portable terminal has changed the moving means at the stop position M. Therefore, by introducing the concept of transit position to the information acquired from the mobile terminal, the mobile terminal holder used it even when multiple moving means were included while moving from O to D Since each moving means can be distinguished, it can greatly contribute to grasping and analyzing the actual state of traffic.

FIG. 6 is a diagram schematically showing the moving means determined from the graph of FIG. 4 and the calculated transfer position N (the graph of FIG. 6 itself is the same as FIG. 4).
Referring to FIGS. 4 and 6, moving means determination unit 8 is based on the maximum moving speed, the map data, and the changing pattern of the moving speed, and the trip O to stop position M <b> 1, stop position M <b> 5 to stop position in FIG. 4. In M6 and stop position M9 to D of trip, it is determined that the owner of the mobile terminal is moving on foot. Further, at the stop position M1 to the stop position M5, it is determined that the owner of the mobile terminal is on the railroad, and at the stop position M6 to the stop position M9, it is determined that the owner of the mobile terminal is on the car.

Next, since the moving means has changed from walking to railway before and after the stop position M1, the stopping position M1 is set as the transit position N1, and the moving means has changed from railway to walking before and after the stop position M5. The stop position M5 is set as a transfer position N2. Similarly, the stop position M6 is set as the transfer position N3, and the stop position M9 is set as the transfer position N4.
Referring to FIG. 2 again, when the moving means is determined and the transfer position N is calculated, these pieces of information are accumulated (stored) in the OD information storage unit 5 as OD information (step S8).

7 is a diagram illustrating an example of a mode in which the information illustrated in FIG. 6 is stored as OD information. FIG. 8 illustrates another example of a mode in which the information illustrated in FIG. 6 is stored as OD information. FIG.
The OD information storage unit 5 stores, as OD information, the time, latitude, longitude, and altitude of the O, D, and connecting position for each trip, and information on the moving means used by the mobile terminal holder between these positions. (See FIG. 7). Further, by dividing one trip for each connecting position, a trip for each moving means may be created and stored as separate OD information for each trip (see FIG. 8). In this way, by determining what kind of moving means the holder of the mobile terminal has used for each transit position, what kind of person is moved from where to what kind of moving means It is possible to grasp in more detail which time zone it moved. Therefore, it can greatly contribute to grasping and analyzing detailed traffic conditions.

FIG. 9 is a flowchart for explaining the control operation of the OD traffic volume calculation device 2, and FIG. 10 is an illustrative view for explaining an example of a traffic volume calculation method.
One OD information stored in the OD information storage unit 5 is extracted by the OD traffic amount calculation unit 9 at regular intervals such as one day, one week, or one month (step S11).
In FIG. 10, a specific area (for example, the central part of Tokyo or the central part of Osaka) is divided into 1 km × 1 km areas, and area codes 1 to 25 are added to the respective areas. Moreover, the OD traffic volume calculation part 9 has memorize | stored the positional information on each area, and can each count the OD traffic volume which moved from the position included in the area code 1 to the position included in each area code 1-25. . Similarly, the OD traffic volume moved from the position included in each area code 2-25 to the position included in each area code 1-25 can be counted.

If all the OD information has not been extracted (No in step S12), the area code of the area including the O position of the extracted OD information is changed to the area code of the area including the position of D. The count value of the moved OD traffic is incremented by one (step S13).
Therefore, for example, as shown in FIG. 10, OD information 1 and OD information 2 are extracted, the area code of the area including the O position of OD information 1 is 1, and the position of D is included. When the area code of the area is 2, the count value of the OD traffic volume moved from the area code 1 to the area code 2 is increased by one. Further, when the area code of the region including the O position of the OD information 2 is 2 and the area code of the region including the position of D is 25, the OD moved from the area code 2 to the area code 25. The traffic count is incremented by one.

  As described above, the moving means determination device 1 calculates the speed when the owner of the mobile terminal moves from O to D based on the position information acquired from the mobile terminal, and based on the calculated speed. It is possible to determine which moving means the holder of the mobile terminal has moved using. Therefore, it is possible to grasp which person moved from where to where, by what means of transportation, and in what time zone without distributing / collecting questionnaires. And time can be greatly reduced. With this reduction in labor and time, the same results as the person trip survey can be achieved on a long-term basis without using questionnaires.

In addition, the OD traffic volume calculation device 2 can calculate the OD traffic volume for each moving means such as a railroad, an automobile, a bicycle, and a walking by using the information on the moving means determined by the moving means determination device 1. it can.
The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.

This is a logical expression for performing such determination processing.

  Each of FIGS. 11A to 11D does not have the logic signals P1 to P4 related to the change pattern of the moving speed, as compared to the logic expressions of FIGS. 5A to 5D. As described above, the present invention is based on the information acquired from the mobile terminal, based on the maximum moving speed between each stop position and each position on the moving route of the map data stored in the map data storage unit. The structure which performs this may be sufficient. In addition, a configuration in which the moving means is determined based only on the maximum moving speed between the stop positions may be employed.

  For example, the OD traffic volume calculation unit divides a specific area into 1km x 1km areas, calculates not only the OD traffic volume between the areas, but also provides each area every several km. OD traffic volume may be calculated, an area may be set for each municipality, OD traffic volume between each municipality may be calculated, or an area may be set for each prefecture to calculate OD traffic volume between prefectures. . Moreover, the structure which performs these calculations in combination may be sufficient.

Further, instead of determining the moving means based on the maximum moving speed between the stop positions, the moving means may be determined based on the average speed between the stop positions, or the instantaneous speed between the stop positions may be used. The moving means may be determined according to the appearance frequency of the instantaneous speed.
In addition, instead of the configuration in which the OD information storage unit is provided in the moving means determination device, a configuration in which the OD information storage unit is provided in the OD traffic amount calculation device may be employed.
