[Processing flow]
Next, a processing flow executed in the above-described trade area analysis system 100 will be described.

(Main process)
FIG. 2 is a flowchart illustrating main processing according to the present embodiment.

  First, in the vehicle-mounted device 1, the control unit 11 transmits probe data indicating the movement history of the vehicle to the server device 2 via the communication unit 14 (step S11). In this case, the control unit 11 generates probe data composed of the vehicle position (latitude / longitude), date / time (year / month / day / hour / minute / second), vehicle speed (speed / hour), etc. at predetermined time intervals (for example, at intervals of 1 second) Then, the generated probe data is transmitted to the server device 2. Specifically, the control unit 11 obtains the position of the vehicle from the positioning data included in the radio wave received by the GPS receiver 14. When the vehicle-mounted device 1 is a navigation device, the position of the vehicle may be obtained using values detected by an independent positioning device (such as an acceleration sensor, an angular velocity sensor, and a distance sensor) included in the navigation device. In that case, the speed of the vehicle can also be obtained from the value detected by the self-supporting positioning device.

  Next, in the server apparatus 2, the communication part 23 receives the probe data transmitted from the onboard equipment 1 (step S21). Then, the control unit 21 stores the probe data received by the communication unit 23 in the storage unit 22 in association with the user identifier in the vehicle-mounted device 1 that has transmitted the probe data (step S22). Then, the control part 21 performs the process (stop information generation process) which produces | generates the stop information containing the position where the vehicle stopped based on the probe data memorize | stored in the memory | storage part 22 (step S23). Next, the control unit 21 executes a process (home position information generation process) for generating home position information indicating the home position of the user of the vehicle based on the stop information stored in the storage unit 22 (step S24). ). Details of the stop information generation process and the home position information generation process will be described later.

  On the other hand, in the terminal device 3, the control unit 31 acquires a survey range corresponding to the facility targeted for the trade area analysis, which is input by the user of the terminal device 3 operating the input unit 33 (step S 31). For example, the user designates the survey range by drawing the shape of the parking lot of the facility that is the object of the trade area analysis using a pointing device such as a mouse. In one example, a survey area is designated by drawing a polygon on an actual map. Thereafter, the control unit 31 transmits the survey range acquired in step S31 to the server device 2 via the communication unit 35 (step S32).

  Next, in the server device 2, the communication unit 23 receives the investigation range transmitted from the terminal device 3 (step S25). Then, the control unit 21 refers to the stop information and the home position information stored in the storage unit 22 and generates a business area analysis result for the facility corresponding to the survey range received by the communication unit 23 (commercial area analysis process). ) Is executed (step S26). That is, the control part 21 produces | generates the statistical information regarding the home position of the user who visited the said facility. Details of the trade area analysis process will be described later. Then, the control part 21 transmits the trade area analysis result produced | generated by step S26 to the terminal device 3 via the communication part 23 (step S27).

  Next, in the terminal device 3, the communication unit 35 receives the trade area analysis result transmitted from the server device 2 (step S33). And the control part 31 displays the trade area analysis result which the communication part 35 received on the display part 34 (step S34).

(Stop information generation process)
Next, with reference to FIG. 3, the stop information generation process executed in step S23 described above will be described.

  FIG. 3 is a flowchart showing stop information generation processing. This flow is executed by the control unit 21 of the server device 2.

  First, in step S <b> 231, the control unit 21 reads probe data associated with the same user identifier (that is, probe data for the same user) from the storage unit 23. As described above, the probe data is generated every predetermined time, but the storage unit 23 stores a plurality of probe data generated every predetermined time in record units. Therefore, in step S231, the control unit 21 reads a group of probe data including a plurality of records associated with the same user identifier. Then, the process proceeds to step S232. In the group of probe data composed of a plurality of records, it is assumed that the probe data corresponding to the oldest record is arranged in order from the oldest with the first row as the probe data.

  In step S232, the control unit 21 acquires the first row data in the probe data read in step S231. That is, the control unit 21 acquires probe data corresponding to the oldest record in a group of probe data including a plurality of records. Then, the process proceeds to step S233.

  In step S233, the control unit 21 acquires the speed of the probe data acquired in step S232 or step S239. Then, the process proceeds to step S234.

  In step S234, the control unit 21 determines whether or not the speed acquired in step S233 is equal to or less than a threshold value. Here, the control unit 21 determines whether or not the probe data acquired in step S232 or step S239 (hereinafter simply referred to as “processing target probe data”) is obtained when the vehicle is stopped. Judging. In one example, the threshold used in step S234 is set to “0 (km / h)”.

  When the speed is equal to or lower than the threshold (step S234: Yes), it can be said that the processing target probe data is obtained when the vehicle is stopped. In this case, the control unit 21 calculates the stop time based on the processing target probe data (step S235). Specifically, the control unit 21 obtains the time difference between the travel date and time of the processing target probe data and the travel date and time of the probe data in the next row of the processing target probe data as the stop time. Then, the process proceeds to step S236.

  On the other hand, when the speed exceeds the threshold value (step S234: No), it can be said that the processing target probe data is not obtained when the vehicle is stopped. In this case, the control unit 21 acquires the probe data of the next row of the processing target probe data (step S239). And a process returns to step S233 and the control part 21 performs the process after step S233 again.

  In step S236, the control unit 21 determines whether or not the stop time calculated in step S235 is greater than or equal to a threshold value. Here, the control unit 21 determines whether or not the stop time calculated in step S235 corresponds to the time when the vehicle stops to stop at a facility or the like. In one example, the threshold used in step S236 is set to “200 (sec)”.

  If the stop time is equal to or greater than the threshold (step S236: Yes), it can be said that the stop time calculated in step S235 corresponds to the time when the vehicle stops to stop at a facility or the like. In this case, the control unit 21 adopts the stop time calculated in Step S235, and generates stop information based on the stop time (Step S237). Specifically, the control unit 21 sets the position and date and time of the processing target probe data as the stop position and the stop date and time, respectively, the stop position and the stop date and time, the stop time calculated in step S235, and the processing target probe. The stop information is generated by associating with the user identifier included in the data. Further, the control unit 21 stores the generated stop information in the storage unit 22. Then, the process proceeds to step S238.

  On the other hand, when the stop time is less than the threshold (step S236: No), it can be said that the stop time calculated in step S235 does not correspond to the time when the vehicle stops to stop at a facility or the like. Therefore, the control unit 21 does not adopt the stop time calculated in step S235, that is, discards the stop time. In this case, the control unit 21 acquires the probe data of the next row of the processing target probe data (step S239). And a process returns to step S233 and the control part 21 performs the process after step S233 again.

  In step S238, the control unit 21 determines whether or not the processing target probe data that has been processed up to step S237 is the last row. If the processing target probe data is for the last line (step S238: Yes), the process ends. On the other hand, when the processing target probe data is not the last row (step S238: No), the control unit 21 acquires the probe data of the next row of the processing target probe data (step S239). And a process returns to step S233 and the control part 21 performs the process after step S233 again.

  Here, a specific example of the stop information generation process will be described with reference to FIG. FIG. 4 illustrates probe data consisting of three records associated with a user identifier of an arbitrary user. In this example, since the speed of the probe data in the second row is less than or equal to the threshold (for example, 0 (km / h) or less), the travel date and time of the probe data in the second row and the next third row A time difference from the travel date and time of the probe data is calculated as the stop time. Specifically, “56 minutes 30 seconds” obtained by subtracting “0:00:02 seconds” from “0:56:32” is calculated as the stop time. Since the stop time is equal to or greater than a threshold (for example, 200 (sec) or more), the stop time is employed to generate stop information. That is, the probe data in the second row is employed for generating stop information. Specifically, the position “latitude: Lat2, longitude: Long2” possessed by the probe data in the second row is set as the stop position, and the travel date and time “January 1, 2013 0:00, possessed by the probe data in the second row. “02 seconds” is the stop position. The stop information is generated by associating such a stop position and stop position, the calculated stop time, and the user identifier.

(Home location information generation process)
Next, with reference to FIG. 5, the home position information generation process executed in step S24 described above will be described.

  FIG. 5 is a flowchart showing home position information generation processing. This flow is executed by the control unit 21 of the server device 2.

  First, in step S <b> 241, the control unit 21 reads out stop information having the same user identifier from the storage unit 23. In this case, the control unit 21 reads a plurality of stop information associated with the same user identifier. Then, the process proceeds to step S242.

  In step S242, the control unit 21 rounds the stop positions included in all the stop information read in step S241 to a certain range. Specifically, the control unit 21 performs a process (that is, clustering) for coarsening the latitude / longitude accuracy corresponding to the stop position in order to absorb the error due to the stop position shift. For example, the control unit 21 performs a process of rounding off the latitude / longitude corresponding to the stop position. Then, the process proceeds to step S243.

  In step S243, the control unit 21 collects stop information that is the same stop position using the stop position rounded in step S242. That is, the control part 21 groups the stop information used as the same stop position. Then, the process proceeds to step S244.

  In step S244, the control part 21 calculates | requires the sum total of the stop time which the stop information put together in step S243 has. In this case, the control part 21 calculates | requires the sum total of the stop time which the stop information in each group has for every group of several stop information. Then, the process proceeds to step S245.

  In step S245, the control unit 21 specifies the longest total of the stop times obtained for each of the plurality of stop information groups in step S244, and whether the specified total stop time is equal to or greater than the threshold value. Determine whether or not. Here, it is determined whether or not the sum of the longest stop time corresponds to the time when the vehicle has stopped at home.

  If the total of the longest stop time is equal to or greater than the threshold (step S245: Yes), it can be said that the total stop time corresponds to the time when the vehicle is stopped at home. In this case, the control unit 21 determines the stop position having the longest total stop time, that is, the common stop position in the stop information group from which the longest stop time is obtained (step S246). Then, the control unit 21 generates home position information by associating the determined home position with the user identifier, and stores the generated home position information in the storage unit 22 (step S247). Thereafter, the process ends.

  On the other hand, when the total of the longest stop time is less than the threshold (step S245: No), it can be said that the total stop time does not correspond to the time when the vehicle is stopped at home. Therefore, the process ends.

  In another example, home position information may be generated for each month. That is, information that further associates the year and month with the home position and the user identifier may be used as the home position information. In that case, the monthly home position information can be generated by reading out the stop information of the same month having the same user identifier in step S241 from the storage unit 23 and performing the processing in step S242 and subsequent steps in the same manner.

(Trade area analysis processing)
Next, with reference to FIG. 6, the trade area analysis process executed in step S26 described above will be described.

  FIG. 6 is a flowchart showing the trade area analysis process. This flow is executed by the control unit 21 of the server device 2.

  First, in step S261, the control unit 21 reads from the storage unit 22 stop information having a stop position included in the investigation range received by the communication unit 23 in step S25 of FIG. In this case, the control unit 21 reads out a plurality of pieces of stop information having stop positions included in the investigation range. Then, the process proceeds to step S262.

  In step S262, the control unit 21 reads from the storage unit 22 home location information having the same user identifier as the user identifier included in the stop information obtained in step S261. In this case, the control unit 21 reads out a plurality of pieces of home position information having the same user identifier as each user identifier of the plurality of stop information. That is, home position information for a plurality of users is read. Then, the process proceeds to step S263.

  In step S263, the control unit 21 calculates the density of the user based on the home positions of the plurality of home position information obtained in step S262. That is, the control unit 21 obtains the density distribution at the home position. In one example, the control unit 21 performs density calculation using a mesh method in which mesh-shaped areas are determined in advance and the number of users existing in each area is counted. In another example, density calculation is performed using kernel density estimation in which a two-dimensional probability density function (Gauss function) is generated around the home position of each user and a total value of all users is obtained. After step S263 described above, the process proceeds to step S264.

  In step S264, the control unit 21 outputs the calculation result of step S263 as a trade area analysis result (that is, statistical information). Then, the process ends. The trade area analysis result output in this way is transmitted to the terminal device 3 in step S27 of FIG. 2, and is displayed on the display unit 34 of the terminal device 3 in step S34 of FIG.

  FIG. 7 shows an example of the trade area analysis result displayed on the display unit 34 of the terminal device 3. FIG. 7 illustrates the home density distribution of the user obtained by the kernel density estimation method. Specifically, the density distribution of the home position of the user who visited the facility indicated by the symbol P1 is expressed using a plurality of different hatchings.

FIG. 8 shows an example of another trade area analysis result. FIG. 8A shows an example of the visit time distribution for the facility that is the target of the trade area analysis. This visit time distribution can be created by counting the number of stops for each stop time based on stop times of a plurality of stop information having stop positions included in the survey range corresponding to the facility. In that case, a plurality of stops at the same time by the same user may be counted as one time.
Good.

  FIG. 8B shows an example of the visit time distribution (in other words, the percentage of visitors by time zone) for the facility that is the target of the trade area analysis. This visit time distribution can be created by counting the number of stops for each stop time period based on the stop date and time of a plurality of stop information having stop positions included in the survey range corresponding to the facility. In that case, a plurality of stops in the same time zone by the same user may be counted as one time.

  FIG. 8 (c) shows an example of the percentage of visitors by city / town / village for the facility subject to the trade area analysis. The percentage of visitors by city / town / village is obtained from a plurality of stop information having stop positions included in the survey range corresponding to the facility, and a plurality of home position information having the same user identifier as the stop information. Based on this, it can be created by counting the number of users for each city. That is, it is only necessary to identify the municipalities to which the home positions of a plurality of users who have visited the facility belong, and count the number of users who have home positions for each municipality. In that case, it is better not to count the same user multiple times.

[Operation and effect of this embodiment]
According to the present embodiment described above, based on the probe data (movement history information) of the vehicle, it is possible to appropriately identify the visitor of the facility targeted for the trade area analysis, and to appropriately set the visitor's home position. Can be requested. Therefore, it is possible to appropriately grasp from which region the visitor is visiting. Thereby, it is possible to provide information useful for marketing to store operators and the like, and it is possible to realize effective advertisement development and sales improvement.

  Here, in the conventional trade area analysis, the registration information of the point card, the information obtained by conducting the questionnaire, and the like are used, which are relatively difficult to obtain information. On the other hand, in this embodiment, since the probe data of the vehicle is collected and the trade area analysis is performed, any place where the vehicle can move can be set as the investigation target. Moreover, according to the present Example, the home position of the visitor of a facility can be investigated simply and accurately.

[Modification]
Below, the modification suitable for an above-described Example is shown. It should be noted that the following modifications can be applied to the above-described embodiments in any combination.

(Modification 1)
As described above, when the home position information is generated for each month, there is a possibility that the home position information cannot be appropriately generated based on the stop information for a month with a small amount of travel. In that case, if the home position information of the months before and after the month for which the home position information could not be generated is obtained and the home positions of the home position information are the same, the home position changes. The home position information may be generated using the home position. As a result, home position information can be appropriately generated even for a user with a small amount of travel, and the amount of data to be investigated can be increased.

(Modification 2)
Regions with high population density tend to have more visitors than regions with low population density. Therefore, the business area analysis result indicating the density distribution of the home positions of the visitors of the facility tends to be influenced by the result. Therefore, it can be said that it is difficult to measure the strength of a visit tendency (visit to visit) with simple density calculation of home position information. Therefore, the trade area analysis result obtained as described above is obtained from data indicating the population bias for each region (the number of households and the population density for each area, for example, obtained by national census etc. The same shall apply hereinafter. ) To normalize. This makes it possible to determine the strength of the relative visit tendency.

  Also, if there is a bias in the user layer that provides probe data, the bias in the user's home position is mixed into the trade area analysis result. Therefore, also in this case, it is preferable to normalize the trade area analysis result (distribution tendency of home position) obtained as described above based on the data indicating the population bias for each region. As a result, it is possible to obtain a trade area analysis result from which the user distribution bias is removed.

(Modification 3)
In the above-described embodiment, the facility visited by the visitor is specified based on the stop information generated from the probe data of the vehicle and the range (survey range) corresponding to the parking lot of the facility designated by the terminal device 3. However, it is not limited to this. In the vehicle-mounted device 1 having a route guidance function, a facility may be set as a destination for route guidance. Therefore, if the server device 2 obtains route guidance records and action histories that include information related to facilities at such destinations, the visitor can select the survey area without specifying the survey range as described above. The facility visited can be identified appropriately. This modification is effective for a complex facility that is difficult to specify only by the parking behavior and position, a parking lot shared by a plurality of facilities, and the like.

(Modification 4)
In the above-described embodiment, the business area analysis is performed for one facility, but the business area analysis may be performed for a plurality of facilities. In that case, the business area analysis results of a plurality of facilities may be compared. Specifically, for different facilities in the same area, it is preferable to compare the density distribution of home positions as a result of the trade area analysis and output the difference. Further, a plurality of facilities may be grouped and the results of trade area analysis for each group may be compared. This makes it possible to compare the business area analysis result of a facility belonging to a certain group with the business area analysis result of a facility belonging to a different group.

(Modification 5)
In the embodiment described above, the range (survey range) corresponding to the parking lot of the facility is specified by the terminal device 3, but the parameters specified for the survey are not limited to this. In another example, the parking lot of the facility may be designated using not only the position coordinate range but also the height. This example is effective when the parking lot of the facility is a three-dimensional parking lot. In still another example, when the server device 2 manages the location of the facility and the parking lot range in association with the facility, the facility name is designated instead of the facility parking lot. You may do it. In this example, the range corresponding to the parking lot of the facility is specified on the server device 2 side from the name of the facility designated on the terminal device 3 side.

  In yet another example, a survey period composed of a survey start date and time and a survey end date and time may be designated. Thereby, it is possible to provide a trade area analysis result corresponding to the survey period.

  In yet another example, user attributes such as gender and age may be specified. In this example, user attributes such as gender and age may be reflected in the trade area analysis result. As a result, it is possible to provide a business area analysis result by gender and a business area analysis result by age.

(Modification 6)
In the above-described embodiment, the home position information indicating the home position is generated based on the stop information, but the present invention is not limited to this. In another example, when the home position is registered in the vehicle-mounted device 1, the home position information is used by directly using the home position registered in the vehicle-mounted device 1 without generating the home position information based on the stop information. Should be generated. In this case, the server device 2 may acquire the home position registered in the vehicle-mounted device 1.
