Description

  The present invention relates to a movement path output control program, a movement path output control method, and an information processing apparatus.

  In recent years, it has been proposed to perform an OD (Origin Destination) survey for investigating the origin and destination of a vehicle based on probe data collected by a probe car. In the OD survey, the traffic route information between the start and end points is mapped on a road map such as a digital road map (DRM: Digital Road Map), so that personal information, company information, sales information, etc. regarding the vehicle are specified. For this reason, for example, it has been proposed to protect personal information, company information, sales information, etc. relating to vehicles by deleting data corresponding to a range of a certain distance centering on the origin and end point of the probe data. In addition, it has been proposed to protect personal information by superimposing a mask image on a point where personal information or the like on a moving route may be specified.

Note that the internal configuration of the control unit 130 is not limited to the configuration illustrated in FIG. 1, and may be another configuration as long as the information processing described below is performed.

  The acquisition unit 131 acquires operation information from each vehicle 5 via the base station 6, the network N, and the communication unit 110. The acquisition unit 131 stores the acquired operation information in the operation information recording unit 121. In addition, for example, when the acquisition unit 131 is instructed to start acquisition of operation information from each vehicle 5 by an administrator of the server device 100, the acquisition unit 131 continues to acquire operation information until an instruction to stop acquisition is given, The storage of the acquired operation information in the operation information recording unit 121 is continued.

  The generation unit 132 refers to the operation information storage unit 121 and generates OD data and route data. Here, a case where the generation unit 132 generates OD data and route data for the vehicle 5 with the vehicle ID “0001” will be described as an example. The generation unit 132 extracts the operation information of the vehicle 5 with the vehicle ID “0001” from the operation information read from the operation information storage unit 121. When the speed of the operation information is 0 km / h, that is, when the time when the vehicle 5 is stopped is, for example, 5 minutes or longer, the generation unit 132 sets the date and time when the vehicle 5 stops as the previous trip end date and time. Next, the generation unit 132 sets the date and time when the speed of the operation information is greater than 0 km / h, that is, the date and time when the vehicle 5 starts moving as the next trip start date and time. Furthermore, the generation unit 132 sets the time when the speed of the operation information is next 0 km / h, for example, 5 minutes or more, and the date and time when the vehicle 5 stops as the trip end date and time. In addition, the stop time of the vehicle 5 for determining the switching of a trip can be made into arbitrary time.

  When the start date / time and end date / time of the trip are determined, the generation unit 132 assigns a trip number, for example, “T1020” to the trip. Trip No. may be given when the trip start date and time is determined. Further, the generation unit 132 determines a trip start zone, for example, “Shibuya-ku, Tokyo 1 ward” based on the location information of the trip start date and time, and based on the location information of the trip end date and time, for example, “Tokyo Metropolitan Ota-ku 4 wards” is decided. That is, the generation unit 132 is a specifying unit that specifies the departure zone and the arrival zone. The generation unit 132 associates the vehicle ID and the trip No with the trip start date / time, the trip start zone, the trip end date / time, and the trip end zone, and stores them in the OD data storage unit 122. Moreover, the production | generation part 132 memorize | stores trip No. of the produced | generated OD data in the record of the corresponding operation information of the operation information storage part 121. FIG.

  Subsequently, the generation unit 132 generates route data based on the extracted operation information of the vehicle 5 with the vehicle ID “0001”. The generation unit 132 maps the date / time, position information, and speed of the operation information of the vehicle 5 on the digital road map. The generation unit 132 can use an existing technique for mapping on a digital road map, that is, map matching. As a result of mapping, the generation unit 132 generates a road link ID of the road where the vehicle 5 is located, a link entry date / time indicating the date / time when the vehicle entered the link, a link entry date / time indicating the date / time of exiting the link, and a link And the average speed of driving. The generation unit 132 stores the road link ID, the link entry date / time, the link exit date / time, and the average speed in the route data storage unit 123 in association with the vehicle ID and the trip No. In addition, the generation unit 132 stores the secondary mesh No to which the link belongs and the link distance that is the distance from the incoming node to the outgoing node of the link in the route data storage unit 123 in association with the vehicle ID and the trip No. To do.

  In the example of the first record illustrated in FIG. 4, the generation unit 132 associates the road link ID “11821184” with the link entry date and time “(blank) in association with the trip number“ T1020 ”of the vehicle 5 with the vehicle ID“ 0001 ”. Is stored in the route data storage unit 123. Further, the generation unit 132 associates the trip date “2013/09/20 12:11:15” and the average speed “23” with the trip number “T1020” of the vehicle 5 with the vehicle ID “0001”. And stored in the route data storage unit 123. Further, the generation unit 132 stores the secondary mesh No “533935” and the link distance “890” in the route data storage unit 123 in association with the trip number “T1020” of the vehicle 5 with the vehicle ID “0001”. To do. Here, the blank of the link entry date and time indicates that there is a trip start point in the middle of the link of the road link ID. Similarly, the blank of the date and time when the link is issued indicates that there is a trip end point in the middle of the link of the road link ID.

  Furthermore, the production | generation part 132 calculates the distance from a link entrance node for every record of operation information based on the map matching result of operation information. The generation unit 132 stores the calculated distance from the link entry node together with the road link ID in the corresponding operation information record of the operation information storage unit 121.

  Returning to the description of FIG. 1, upon receiving the designation information from the terminal device 10 operated by the analyst, the accepting unit 133 accepts designation of the vehicle 5 that outputs the travel route. Here, the designation of the vehicle 5 in the terminal device 10 may be designated by, for example, the vehicle ID or the number of the vehicle 5, or a vehicle that has displayed a map, selected a position on the map, and passed the selected position. You may make it select from the list of 5. For example, when the trip start zone (departure zone) and the trip end zone (arrival zone) are designated, the vehicle 5 at the terminal device 10 is designated as the start / end point of each zone. You may make it do. In addition, although the vehicle 5 to be designated is described as one vehicle in the following description, a plurality of vehicles 5 may be provided. The accepting unit 133 outputs the accepted designation information to the mask unit 134.

  The mask unit 134 is a mask processing unit that performs mask processing. When the designation information is input from the reception unit 133, the mask unit 134 refers to the operation information storage unit 121, and obtains the operation information of the starting point of the vehicle 5 based on the vehicle ID of the vehicle 5 specified by the specification information. get. For example, the mask unit 134 searches the operation information storage unit 121 sorted in order from the oldest date and time in order from the first record, and firstly, the operation information of the record with the matching vehicle ID is the operation information of the starting point of the vehicle 5. Get as. In addition, when there are a plurality of trips for the vehicle 5, the mask unit 134 first displays the operation information of the record having the same vehicle ID in each of the operation information with different trip numbers as the operation of the starting point of each trip. It may be acquired as information. In other words, the mask unit 134 is also an extraction unit that extracts the history information of the vehicle 5 designated from the operation information storage unit 121.

  Similarly, the mask unit 134 acquires operation information of the end point of the vehicle 5. The mask unit 134 searches, for example, the operation information storage unit 121 sorted in order from the oldest date and time in order from the top record, and finally, the operation information of the record with the matching vehicle ID is the operation information of the end point of the vehicle 5. Get as. In addition, when there are a plurality of trips for the vehicle 5, the mask unit 134 displays the operation information of the record whose vehicle ID finally matches among the operation information having different trip numbers, and the operation at the end point of each trip. It may be acquired as information.

  When acquiring the start / end operation information, the mask unit 134 calculates the distance from the start point to the link departure node of the link to which the start point belongs. Here, the calculation of the distance between the start and end points of the trip will be described. FIG. 5 is a diagram illustrating an example of calculating the distance from the starting point or the ending point. As shown in FIG. 5, the generation unit 132 generates route data 24 by map-matching the operation information 23 for a digital road map represented by the node 21 and the link 22, for example, and stores the route data 24 in the route data storage unit 123. Remember. The mask unit 134 calculates the distance, for example, every second based on the position information of each operation information 23 from the starting point 25 in the middle of the link to the link outgoing node 21A, and adds up the distance from the starting point to the linked outgoing node. Calculate the distance. The distance of the end point 26 portion can be the distance from the link entry node corresponding to the operation information of the trip end point 26, that is, the distance from the link entry node 21B to the end point 26 shown in FIG.

  The mask unit 134 refers to the route data storage unit 123 and acquires one piece of route data corresponding to the trip No. included in the operation information of the starting point of the vehicle 5 in order from the top. In the following description, the acquired route data is also simply referred to as a link. The mask unit 134 calculates the distance from the starting point. When acquiring the route data including the starting point, the mask unit 134 sets the calculated distance from the starting point to the linked node as the distance from the starting point. When acquiring the route data that does not include the starting point, the mask unit 134 calculates the distance from the new starting point by adding the link distance of the route data to the distance from the starting point.

  Further, the mask unit 134 refers to the route data storage unit 123 and acquires one piece of route data corresponding to the trip No. included in the operation information at the end point of the vehicle 5 in order from the last. The mask unit 134 calculates the distance from the end point. When acquiring the route data including the end point, the mask unit 134 sets the distance from the link entry node included in the operation information of the end point as the distance from the end point. When acquiring the route data not including the end point, the mask unit 134 calculates the distance from the new end point by adding the link distance of the route data to the distance from the end point. In the following description of the mask part 134, since the same processing is performed for each of the starting point and the ending point, the description will be made collectively as the starting point and the ending point.

  The mask unit 134 determines whether or not there is a branch in the link outgoing node (link incoming node in the case of an end point) of the acquired link. If there is no branch, the mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123 and acquires the next route data. When there is a branch, the mask unit 134 determines whether the distance from the start / end point exceeds the threshold. Here, the threshold value can be an arbitrary numerical value such as 100 m, 200 m, or 300 m, for example.

  When the distance from the start / end point does not exceed the threshold value, the mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123. The mask unit 134 adds the distance for the evaluated link to the distance from the start / end point. The mask unit 134 acquires one piece of next route data, and repeats the determination as to whether or not the distance from the start and end points exceeds the threshold value.

  When the distance from the start / end point exceeds the threshold, the mask unit 134 calculates the time from the start / end point. Here, the time from the starting point is calculated by subtracting the date and time of the operation information of the starting point from the link entry date and time of the route data. Further, the time from the end point is calculated by subtracting the link start date / time of the route data from the date / time of the end point operation information.

  The mask unit 134 determines whether or not the calculated time from the start and end points exceeds a threshold value. Here, the threshold value can be an arbitrary numerical value such as 30 seconds, 60 seconds, or 90 seconds, for example. The mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123 when the calculated time from the start and end points does not exceed the threshold value. The mask unit 134 acquires one piece of next route data. The mask unit 134 calculates the time from the start / end point in the same manner as described above, and repeats the determination of whether the time from the start / end point exceeds the threshold value.

  When the time from the calculated start / end point exceeds the threshold, the mask unit 134 ends the start / end mask process. When the mask process at the start / end point is completed, the mask unit 134 instructs the display control unit 135 to generate a display screen for confirming the route data and OD data to be output after the mask process is completed.

  Here, an example of the mask process will be described with reference to FIG. FIG. 6 is a diagram for explaining an example of mask processing. As shown in FIG. 6, for example, the trip 31 indicates a movement route when the vehicle 5 starts from the start point 32 and moves to the end point 33. At this time, the mask unit 134 masks, for example, three links 34 from the starting point 32. For example, the mask unit 134 masks the links 35 corresponding to three links from the end point 33. In the example of FIG. 6, even when the start point 32 and the end point 33 are masked by the trip start zone 36 and the trip end zone 37, the departure section and the arrival section of the vehicle 5 on the trip 31 can be determined.

  When the display control unit 135 is instructed to generate a display screen from the mask unit 134, the display control unit 135 reads out the route data and OD data to be output from the route data storage unit 123 and the OD data storage unit 122, respectively. The display control unit 135 generates a display screen for confirming the route data and OD data to be output based on the read route data and OD data. The display control unit 135 transmits the generated display screen to the terminal device 10 via the communication unit 110 or the like, and displays the display screen on a display unit (not shown) of the terminal device 10.

  FIG. 7 is a diagram illustrating an example of the display screen. As shown in FIG. 7, the display screen 41 displays, for example, a trip 42, a trip start zone 43, and a trip end zone 44 as a travel route on which mask processing has been performed. Thereby, the analyst can easily confirm that the movement history in the vicinity of the start / end point is masked. The display control unit 135 may display a plurality of trips on the display screen.

  When the display screen is confirmed by the analyst and the confirmed information is received from the terminal device 10, the display control unit 135 outputs the route data and the OD data, and transmits the route data to the terminal device 10, for example. Further, when outputting the route data and the OD data, the display control unit 135 may output the departure zone and the arrival zone, that is, the trip start zone and the trip end zone. That is, the display control unit 135 is an output unit that outputs a travel route on which mask processing has been performed, a departure zone, an arrival zone, and the like.

  Next, the operation of the movement route output system 1 of the embodiment will be described. First, the process which acquires operation information from each vehicle 5 and produces | generates OD data and route data is demonstrated.

  The acquisition unit 131 of the server device 100 acquires operation information from each vehicle 5 via the base station 6, the network N, and the communication unit 110. The acquisition unit 131 stores the acquired operation information in the operation information recording unit 121. The generation unit 132 refers to the operation information storage unit 121 and generates OD data and route data.

  FIG. 8 is a flowchart illustrating an example of the OD data generation process. The generation unit 132 refers to the operation information storage unit 121 and acquires a record of the start point and end point of the operation information (step S1). The generation unit 132 determines a trip start zone and a trip end zone based on the position information of the start point and end point records (step S2). The generation unit 132 associates the vehicle ID and the trip No with the trip start date / time, the trip start zone, the trip end date / time, and the trip end zone, and stores them in the OD data storage unit 122 (step S3).

  Further, the generation unit 132 stores the road link ID, the link entry date / time, the link departure date / time, and the average speed in the route data storage unit 123 in association with the vehicle ID and the trip No. Further, the generation unit 132 stores the secondary mesh No to which the link belongs and the link distance of the link in the route data storage unit 123 in association with the vehicle ID and the trip No.

  Next, the mask process of the origin of route data will be described. FIG. 9 and FIG. 10 are flowcharts showing an example of the starting point masking process. The terminal device 10 transmits the designation information to the server device 100 by an analyst's operation. When receiving the designation information from the terminal device 10, the accepting unit 133 of the server device 100 accepts designation of the vehicle 5 that outputs the travel route. The accepting unit 133 outputs the accepted designation information to the mask unit 134.

  When the designation information is input from the reception unit 133, the mask unit 134 refers to the operation information storage unit 121, and obtains the operation information of the starting point of the vehicle 5 based on the vehicle ID of the vehicle 5 specified by the specification information. Obtain (step S11). When the mask unit 134 acquires the operation information of the starting point, the mask unit 134 calculates the distance from the starting point to the link outgoing node of the link to which the starting point belongs (step S12).

  The mask unit 134 refers to the route data storage unit 123 and acquires one piece of route data corresponding to the trip number included in the operation information of the starting point of the vehicle 5 in order from the top (step S13). The mask unit 134 calculates the distance from the starting point (step S14). The mask unit 134 determines whether or not there is a branch at the link output node of the acquired link (step S15). If there is no branch (No at Step S15), the mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123 (Step S16), and returns to Step S13.

  When there is a branch (Yes at Step S15), the mask unit 134 determines whether the distance from the starting point exceeds the threshold (Step S17). If the distance from the starting point does not exceed the threshold (No at Step S17), the mask unit 134 deletes the record of route data corresponding to the evaluated link from the route data storage unit 123 (Step S18). The mask unit 134 adds the distance for the evaluated link to the distance from the starting point (step S19). Further, the mask unit 134 acquires one piece of next route data (step S20), and returns to step S17.

  When the distance from the starting point exceeds the threshold (step S17: Yes), the mask unit 134 calculates the time from the starting point (step S21). The mask unit 134 determines whether or not the time from the calculated starting point exceeds a threshold value (step S22). When the time from the calculated starting point does not exceed the threshold (No at Step S22), the mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123 (Step S23). The mask unit 134 acquires one piece of next route data (step S24). The mask unit 134 calculates the time from the starting point (step S25), and returns to step S22. When the time from the calculated starting point exceeds the threshold (Yes at Step S22), the mask unit 134 ends the masking process at the starting point. Thereby, the movement history near the starting point of the route data can be masked.

  Next, an example of end point mask processing will be described. FIG. 11 and FIG. 12 are flowcharts showing an example of the endpoint mask process. When the designation information is input from the reception unit 133, the mask unit 134 of the server device 100 refers to the operation information storage unit 121 and based on the vehicle ID of the vehicle 5 designated by the designation information, the end point of the vehicle 5 The operation information is acquired (step S31).

  The mask unit 134 refers to the route data storage unit 123 and acquires one piece of route data corresponding to the trip No. included in the operation information at the end point of the vehicle 5 in order from the last (step S32). Note that when the mask processing of the starting point is performed first, the mask unit 134 refers to the route data storage unit 123 in which the route data for which the mask processing of the starting point is completed is stored. The mask unit 134 calculates the distance from the end point (step S33). The mask unit 134 determines whether or not there is a branch at the link entry node of the acquired link (step S34). If there is no branch (No at Step S34), the mask unit 134 deletes the route data record corresponding to the evaluated link from the route data storage unit 123 (Step S35), and returns to Step S32.

  When there is a branch (Yes at Step S34), the mask unit 134 determines whether the distance from the end point exceeds the threshold (Step S36). When the distance from the end point does not exceed the threshold (No at Step S36), the mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123 (Step S37). The mask unit 134 adds the distance for the evaluated link to the distance from the end point (step S38). Further, the mask unit 134 acquires one piece of next route data (step S39), and returns to step S36.

  When the distance from the end point exceeds the threshold (step S36: Yes), the mask unit 134 calculates the time from the end point (step S40). The mask unit 134 determines whether or not the calculated time from the end point exceeds the threshold value (step S41). When the calculated time from the end point does not exceed the threshold (No at Step S41), the mask unit 134 deletes the record of the route data corresponding to the evaluated link from the route data storage unit 123 (Step S42). The mask unit 134 acquires one piece of next route data (step S43). The mask unit 134 calculates the time from the end point (step S44), and returns to step S41. When the calculated time from the end point exceeds the threshold (Yes at Step S41), the mask unit 134 ends the end point mask process. Thereby, the movement history near the end point of the route data can be masked.

  When the mask process at the start / end point is completed, the mask unit 134 instructs the display control unit 135 to generate a display screen for confirming the output route data and OD data for which the mask process is completed.

  Next, output processing for outputting route data and OD data will be described. FIG. 13 is a flowchart illustrating an example of output processing. When instructed to generate a display screen from the mask unit 134, the display control unit 135 of the server device 100 reads out the route data and OD data to be output from the route data storage unit 123 and the OD data storage unit 122, respectively. The display control unit 135 generates a display screen for confirming the route data and OD data to be output based on the read route data and OD data (step S51).

  The display control unit 135 transmits the generated display screen to the terminal device 10 via the communication unit 110 or the like, and displays the display screen on a display unit (not shown) of the terminal device 10 (step S52). When the analyzer confirms the display screen and receives the confirmed information from the terminal device 10 (step S53), the display control unit 135 outputs the route data and the OD data (step S54) and transmits it to the terminal device 10, for example. To do. Thereby, since the movement route output system 1 can mask the movement history in the vicinity of the start and end points of the route data, the route data used for the OD investigation can be collected while maintaining the trade secret of each company that the vehicle 5 enters and exits.

  Thus, when the server apparatus 100 outputs the travel route of the vehicle based on the travel history of the vehicle 5, the server apparatus 100 performs a mask process for masking the travel history in the vicinity of the departure point and / or the arrival point in the travel history. Then, the movement path on which the mask process has been performed is output. As a result, it is possible to collect data in which the trade secrets of each company are retained.

  Further, when the server device 100 outputs the movement route of the vehicle based on the movement history of the vehicle 5, the server device 100 specifies a departure block including a departure point or an arrival block including an arrival point among a plurality of blocks. . In addition, the server apparatus 100 outputs the travel route on which the mask process has been performed, and outputs the departure section and the arrival section together. As a result, it is possible to determine the starting and ending zones while maintaining the trade secret of each company that the vehicle 5 enters and exits, and it is possible to collect route data used for the OD investigation.

  Further, the server apparatus 100 performs the masking process on the departure point and / or the point included in the range of the predetermined road distance from the arrival point. As a result, since the route data is separated from the departure point or the arrival point by a predetermined road distance, it is possible to collect route data useful for OD investigation while maintaining the trade secret of each company that the vehicle 5 enters and leaves.

  In addition, the server apparatus 100 has a movement history including time information, and performs mask processing in a range from a time at the departure point to a time at which a predetermined time has elapsed and / or from a time at the arrival point to a predetermined time. Execute for a range up to a time that is only back. As a result, the route data is separated from the departure point or the arrival point by the distance traveled by the vehicle 5 until a predetermined time elapses, so that it is useful for OD investigation while maintaining the trade secrets of the companies that the vehicle 5 enters and exits. Route data can be collected.

  In addition, the server device 100 performs the masking process on a starting point and / or a point where a road from the arrival point branches a predetermined number of times. As a result, since there are a plurality of candidate locations for departure points or arrival points, it is possible to collect route data useful for OD investigation while maintaining the trade secret of each company that the vehicle 5 enters and exits.

  In addition, when a departure zone and an arrival zone of a plurality of zones are designated, the server apparatus 100 sets the designated departure zone as a departure point and the designated arrival zone as an arrival point. A process of extracting history information of the vehicle 5 is performed. As a result, it is possible to collect the route data useful for the OD investigation while maintaining the trade secret of each company that the vehicle 5 enters and exits for the vehicle 5 that moves between the designated departure point and arrival point.

  In the above embodiment, the mask processing range is determined based on the road branch, distance, and time. However, the present invention is not limited to this. For example, mask processing may be executed from a starting point or arrival point to a point passing a predetermined number of signals, or mask processing may be executed up to the boundary point of the starting or arriving zone. Good. Thereby, it becomes difficult to specify the departure point or the arrival point, and it is possible to collect the route data useful for the OD investigation while maintaining the trade secret of each company that the vehicle 5 enters and leaves.

  As described above, the server apparatus 100 performs the mask process on the starting point and / or the point from the arrival point to the point where a predetermined number of signals pass. As a result, the starting point or the arriving point is more difficult to be specified, and the server apparatus 100 can collect route data useful for the OD survey while maintaining the trade secret of each company that the vehicle 5 enters and exits.

  In addition, the server apparatus 100 performs the mask process up to the boundary point of the departure section or the arrival section. As a result, the starting point or the arriving point is more difficult to be specified, and the server apparatus 100 can collect route data useful for the OD survey while maintaining the trade secret of each company that the vehicle 5 enters and exits.

  Moreover, in the said Example, although route data and OD data were output, it is not limited to this. For example, either one of route data and OD data may be output, or operation information corresponding to the route data subjected to mask processing is output together with one or more data of route data and OD data. You may make it do.

  Moreover, in the said Example, although the mask process was performed about the departure point and the arrival point (start / end point), it is not limited to this. For example, when the departure point is a station, a port, or the like that does not require mask processing, the departure point that should be grasped can be specified by not performing mask processing for the departure point.

  Moreover, in the said Example, although the mask process was performed based on the road distance from the departure point and the arrival point, it is not limited to this. For example, the distance may be defined by a radius from the departure point and the arrival point.

  Moreover, in the said Example, when the designation | designated of the vehicle 5 or the start division and the arrival division were designated, the vehicle 5 which makes each division (zone) the start / end point was designated, However, It is not limited to this. For example, designation of either a departure zone including a departure point or an arrival zone including an arrival point may be accepted. Thereby, even when the departure zone or the arrival zone is designated, the data in which the trade secrets of the respective companies are held can be collected.

  As described above, when one of a departure block including a departure point or an arrival block including an arrival point is specified, the server device 100 sets the specified departure block as a departure point. The history information of the vehicle 5 to be used or the history information of the vehicle 5 having the designated arrival area as the arrival point is extracted. Further, when the server apparatus 100 outputs the movement route of the vehicle 5 based on the extracted movement history of the vehicle 5, the server apparatus 100 performs a mask process for masking the movement history in the vicinity of the departure point and / or the arrival point in the movement history. Execute and output the travel route that has been masked. As a result, it is possible to collect data in which the trade secrets of each company are retained.

  In addition, each component of each part illustrated does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each unit is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads or usage conditions. Can be configured. For example, the acquisition unit 131 and the generation unit 132 may be integrated.

  Furthermore, various processing functions performed by each device may be executed entirely or arbitrarily on a CPU (or a microcomputer such as an MPU or MCU (Micro Controller Unit)). In addition, various processing functions may be executed in whole or in any part on a program that is analyzed and executed by a CPU (or a microcomputer such as an MPU or MCU) or on hardware based on wired logic. Needless to say, it is good.

  By the way, the various processes described in the above embodiments can be realized by executing a program prepared in advance by a computer.

The The hard disk device 208 also stores an operation information storage unit 121, an OD data storage unit 122, a route data storage unit 123, and various data for realizing an output control program for the travel route. The input device 202 receives input of various information such as management information from an administrator of the computer 200, for example. The monitor 203 displays, for example, a management information screen and various screens for the administrator of the computer 200.
