Description

The present invention relates to a facility use area analyzer and a facility use area analysis program.

Various methods have been proposed for facility use area analysis technology for analyzing the distribution of areas where users of facilities such as stores live, for example, analysis of virtual trade areas. As such a technology, a method of drawing concentric circles with a certain distance around the store, calculating the expected number of customers using the demographics within that range, and analyzing the virtual trade area, instead of concentric circles with a certain distance, A virtual trade area that is closer to reality, such as a method that defines a certain range as a virtual trade area using the distance along the road, and a method that defines the same range of actual travel time as a virtual trade area in consideration of traffic conditions, etc. There is a way to decide.

For example, Patent Document 1 below discloses a method of excluding a place where passage is difficult, such as a railroad or a river, or limiting the range of influence when determining a virtual trade area. ..

Japanese Unexamined Patent Publication No. 2017-59000

However, in the above-mentioned conventional technology, topographical restrictions such as railroads and rivers are taken into consideration. Routine user behavior patterns such as returning are not taken into consideration. That is, the relationship between the location of the facility to be used and the route that the user uses on a daily basis could not be sufficiently reflected in the analysis of the virtual trade area and the like.

For example, when purchasing products that are used on a daily basis, the nearest store may be used from home, but even if you are away from home, you may be on the return route from the nearest station, which is a regional base, when commuting to work or school. If you are in a store in Tokyo, you can often buy products. Therefore, when considering a virtual trade area, it is necessary to reflect the purchasing behavior of such products. On the contrary, even if the store is closest to the home, if it is not on the return route, there are few cases where the store passes through the home and uses the store, and there are many cases where the purchase is completed at the store on the route.

In such a case, by applying the analysis method of the virtual trade area according to the movement of the user flowing from the station to the home, apart from the analysis method of the virtual trade area by the yen trade area centered on the so-called store location. It is possible to perform more accurate analysis of virtual trade areas.

In addition, this method is not limited to stores when purchasing products, for example, restaurants including restaurants, coffee shops, fast food stores, taverns, etc., living service stores such as cleaning stores, rental video stores, banks, etc. When considering the location of facilities that residents use on a daily basis, such as the location of automatic cash deposit and payment machines (ATMs), cultural facilities such as fitness clubs and libraries, and procedure counters outside government buildings such as city halls and ward offices. It can also be used as reference information.

An object of the present invention is to be able to analyze a facility use area consisting of the distribution of residence points of users of the facility with high accuracy in order to use it when considering the location of a facility such as a store or a public facility as described above.

In FIG. 1, the facility use area analysis device 100 includes a map data acquisition unit 10, a route data acquisition unit 11, a route data generation unit 12, a route data extraction unit 13, a route data determination unit 14, a residence point determination unit 16, and facility use. The area generation unit 18, the display control unit 20, the communication unit 22, the storage unit 24, and the CPU 26 are included. In addition to the CPU 26, an accelerator such as a GPU may be used. The facility use area analyzer 100 is equipped with a CPU 26, ROM, RAM, non-volatile memory, I / O, a communication interface, etc., and is configured as a computer that controls the entire device and performs various calculations. For example, it is realized by the CPU 26 and a program that controls the processing operation of the CPU 26.

The map data acquisition unit 10 acquires the map data necessary for the facility use area analysis within the target range of the facility use area analysis. The map data is in a data format that can be used in the geographic information system (GIS) installed in the facility use area analysis device, and is the road network data used when creating route data, and the exit of the train station as a regional base. , Location information of bus stops, etc., location information of facilities subject to facility use area analysis, etc. In addition, the map data includes resident information such as regional demographic data and / or resident data in order to acquire the residence point of the facility user, and is a map for the background when displaying the map. The information may include data on administrative boundaries (city / ward / town / village boundaries, town chome boundaries), road shapes, railway lines, rivers, coastlines, public facilities, factories, and the like. The acquired map data is stored in the storage unit 24.

Here, among the map data acquired by the map data acquisition unit 10, for example, the position information of the target facility such as a store may be given the attribute information of the facility. In the case of a store, for example, the attribute information is information such as the type of the store, the distinction between affiliated stores and competing stores, the sales floor area, and the opening time, and is used as an index when analyzing the trade area.

Further, the regional demographic data included in the map data acquired by the map data acquisition unit 10 is in the form of a mesh in which the area is divided into squares for each predetermined distance within the target range of the facility use area analysis. It is data with population statistics such as the number of residents for each mesh. Alternatively, it may be surface data (polygon data) having an indefinite shape such as a city, ward, town, town, chome, block, or statistical survey area without taking a mesh form. In this case, each polygon data is a resident. Has population statistics such as numbers. Resident data is data in which the number of residents is assigned to each building shape or building point within the scope of facility use area analysis, or resident information such as resident information and customer information (number of residents). ) Is the data to which the address information is added.

The route data acquisition unit 11 acquires route data on a map starting from the facility user's residence point and ending at the regional base within the target range of the facility use area analysis, and stores the route data in the storage unit 24. Here, the above-mentioned facility is a facility used by a store, a public facility, or other users, and is a facility (target facility) to be analyzed by the facility use area analyzer 100 according to the embodiment. Further, the facility use area is a residential area (a set of residential points) of a user who uses the above facility, and the target range of the facility use area analysis is the target of the analysis of the facility use area analyzer 100 according to the embodiment. It is an area including the above-mentioned residential area, target facility, and regional base. In addition, regional bases are bases where users make daily round trips to and from their place of residence, such as train station exits, bus stops, company buildings or factory parking lots when commuting by car, and so on. be. In addition, the regional base can be set as a regional base area in a face-to-face manner. A point, for example, a major intersection, etc., may be one of the regional bases. Here, as described above, the route data is a route on the map starting from the residence point of the facility user and ending at one of the above regional bases, and does not necessarily have to be the shortest route.

The route data acquisition unit 11 may create various route data in advance and acquire route data from an external server holding the route data via the communication unit 22, a pointing device such as a keyboard and a mouse, a touch panel, and the like. The user may input the data by an appropriate input means of the above and have the route data acquisition unit 11 acquire the data. Examples of the route data include data of the movement routes of a large number of automobiles traveling on an actual road. Further, the route data generation unit 12 according to the embodiment may be configured to generate the route data. The route data is generated by using the road network data by designating the map with the residential point as the starting point and one of the regional bases as the ending point.

The route data generation unit 12 generates route data when the route data acquisition unit 11 cannot acquire the route data. In this case, the route data generation unit 12 includes resident information such as demographic data and / or resident data for acquiring the residence point of the facility user, road network data, and area, which are included in the map data. For example, the location information of the station as a base and the location information of the target facility of the facility use area analysis are read from the storage unit 24, the residence point and the regional base of the facility user who is the target of generating the route data are selected, and the road network is selected. Use the data to generate route data that connects the two (starting from the facility user's residence point and ending at the regional base). The route data is preferably the shortest route connecting the residential point and the regional base, but it does not necessarily have to be the shortest route. The route data corresponding to the residence point of the facility user is not limited to one, and a plurality of available routes may be generated other than the shortest route. The generated route data is stored in the storage unit 24.

Further, the route data generation unit 12 reads out the position information of the target facility from the map data stored in the storage unit 24 in advance, and passes through the target facility from the residential point or within a predetermined range. Route data to reach the regional base may be generated. This route data will be the facility use route data of the target facility, which will be described later. Further, for each target facility, route data may be generated via the target facility or passing within a predetermined range. The generated route data is stored in the storage unit 24.

The route data generation unit 12 sets a predetermined range from the target facility as a distance according to the attribute of the target facility and / or the transportation means of the facility user. The attributes of the target facility include, for example, the sales floor area in the case of a large-scale commercial facility such as a supermarket. In this case, if the sales floor area is large, a wide range is set, and if the sales floor area is small, a narrow range is set for each target facility. In addition, the means of transportation for facility users include walking, bicycles, automobiles, etc., and a narrow range is set for walking that does not make much detours, and a wide range is set for automobiles that can make some detours. .. The setting of a predetermined range by the means of transportation is uniformly performed within the target range of the facility use area analysis. The predetermined range described above can be determined in advance as a specific numerical stage according to the attributes of the target facility and / or the means of transportation of the facility user. Further, the predetermined range described above may be set and input by the operator, for example, or may be acquired from an external server or the like via the communication unit 22. Information in a predetermined range from the set target facility is also stored in the storage unit 24.

The route data generation unit 12 may determine the residence point of the facility user based on the resident information read from the storage unit 24. If the resident information is the address information of the resident or the location information of the place of residence, the point of the address information or the location information is set as the residence point of the facility user and the starting point of the route data. If the resident information is statistical data for each polygon shape that has an indefinite shape such as a mesh form, a town street, a district, or a statistical survey area, for example, an arbitrary point in the polygon shape (for example, polygon data). A label point may be generated at a center point inside a polygon, a center point inside a polygon, or the like, and the point (label point) may be used as a residence point of a facility user as a starting point of route data. For example, line data from the above starting point to a point on the nearest road network data is added, and route data to the ending point, which is a regional base, is generated.

The route data generation unit 12 may search for a regional base closest to the residential point as a regional base corresponding to the residential point of the facility user, or is determined for each address information of the residential point, for example. You may accept the local bases you are in. Further, there may be a plurality of regional bases corresponding to one residential point, and route data may be generated for each of a plurality of regional bases from one residential point.

The route data extraction unit 13 reads the route data and the road network data from the storage unit 24, and connects the residential point (starting point) and the regional base (end point) of the route data with the shortest route on the map. The shortest route data is generated using the read road network data. Further, the route data extraction unit 13 calculates the distance between each route data (the route data whose starting point and ending point are the same as the shortest route data) and the generated shortest route data, and the difference is within a predetermined threshold value. A certain route data is extracted and stored in the storage unit 24. By doing so, the route data connecting the residential point and the regional base will be excluded from the route data that is significantly detoured compared to the case where the shortest route is used.

The route data extraction unit 13 sets the predetermined threshold value as a numerical value according to the attribute of the target facility and / or the transportation means of the facility user. The attributes of the target facility include, for example, the sales floor area in the case of a large-scale commercial facility such as a supermarket, as in the case of the route data generation unit 12. In this case, if the sales floor area is large, a large threshold value is set, and if the sales floor area is small, a small threshold value is set for each target facility. Further, as the means of transportation of the facility user, as in the case of the route data generation unit 12, walking, a bicycle, a car, etc. can be mentioned, and in the case of walking that does not make a lot of detours, a small threshold value can be used for some detours. A large threshold is set when using a car. The threshold value is set uniformly within the scope of the facility use area analysis by the means of transportation, but if the distance between the residence point and the regional base is relatively short, the threshold is set small as walking movement, and the threshold is set between the residence point and the regional base. If the distance is relatively long, a large threshold value may be set for vehicle movement. Further, the threshold value may be set not as a difference in distance but as a ratio between the distance of the route data and the distance of the shortest route, for example, such that the distance of the route data is within 110% of the distance of the shortest route data. .. The threshold value described above may be set and input by the operator, for example, or may be acquired from an external server or the like via the communication unit 22. The set threshold value is also stored in the storage unit 24.

The route data determination unit 14 reads the route data (route data in which the difference in distance from the shortest route data is within a predetermined threshold value) extracted by the route data extraction unit 13 from the storage unit 24, and the route data is It is determined whether or not the data passes within a predetermined range from the target facility, and if the route data is passed, the route data is determined to be the facility use route data of the target facility. For each of all the route data extracted by the route data extraction unit 13, it is determined whether or not the passage is within a predetermined range for all the target facilities, and the determination result is stored in the storage unit 24. Here, the above-mentioned "passing within a predetermined range" means, for example, generating a circle having a predetermined radius centered on the target facility and passing the route data within this circle, which is a known technique of GIS (GIS). Using the spatial analysis function of the Geographic Information System), it is determined whether all or part of the route data is included in the circle graphically. In addition, for example, when the area around the target facility is divided by railroads, rivers, arterial roads, etc., the distance along the road is a predetermined length using the road network data with the target facility as the starting point. The range of the road within the range may be extracted, and the route data passing through the road within the range may be regarded as "passing within the predetermined range".

The route data determination unit 14 sets a predetermined range from the target facility as a distance according to the attribute of the target facility and / or the transportation means of the facility user. The attributes of the target facility include, for example, the sales floor area in the case of a large-scale commercial facility such as a supermarket, as in the case of the route data generation unit 12. In this case, if the sales floor area is large, a wide range is set, and if the sales floor area is small, a narrow range is set for each target facility. Further, as the means of transportation of the facility user, as in the case of the route data generation unit 12, walking, a bicycle, a car, etc. can be mentioned, and in the case of walking that does not make a lot of detours, a narrow range can be detoured to some extent. A wide range is set when using a car. The setting of a predetermined range by the means of transportation is uniformly performed within the target range of the facility use area analysis. The predetermined range described above can be determined in advance as a specific numerical stage according to the attributes of the target facility and / or the means of transportation of the facility user. Further, the predetermined range described above may be set and input by the operator, for example, or may be acquired from an external server or the like via the communication unit 22. Information in a predetermined range from the set target facility is also stored in the storage unit 24.

The residence point determination unit 16 reads out the facility use route data determined by the route data determination unit 14 from the storage unit 24, and uses the facility that has passed within the predetermined range of each target facility for each target facility. The route data is extracted, and the residence points of all the facility users who are the starting points of the extracted facility use route data are determined to be the user residence points of the target facility and stored in the storage unit 24. Here, when one facility use route data passes within a predetermined range of a plurality of target facilities, the residence point of the facility use route data is determined as a user residence point for each target facility. To.

It should be noted that the residence point of the facility user, which is the starting point of the above route data, is, for example, in the case of area information such as demographics in which the area is divided into grid shapes for each predetermined distance, or in the case of area statistics such as city wards. In the case of surface data that has an irregular shape such as a town / village, town chome, or statistical survey area, the entire range is determined as the user residence point of the target facility, and it is a part of the facility use area of the target facility described later. Become.

The facility use area generation unit 18 reads out the user residence point determined by the residence point determination unit 16 for each target facility from the storage unit 24, and sets the set of user residence points in the area where the user of the target facility resides. It is generated as a facility use area of the target facility, and is stored in the storage unit 24. The set of user residence points is the range within the outer periphery where the user residence points exist, and the range is the facility use area of the target facility. If the residence point of the facility user is area information, the area where the area is combined is used as the facility use area of the target facility. Further, the facility use area generation unit 18 reads out the resident information from the storage unit 24 and totals the number of residents from the generated resident information in the facility use area of the target facility to obtain the facility of the target facility. You may estimate the number of users. When one user's residence point is determined as the user's residence point of a plurality of target facilities, the facility use area is duplicated in the same range.

The display control unit 20 reads out the facility use area and the like of the target facility from the storage unit 24, reads out the map data and the like used for the background map in addition to the target facility and the regional base from the storage unit 24, and superimposes them. The image is created in the state of being displayed, and the liquid crystal display device and other appropriate display devices are controlled and displayed.

The communication unit 22 is configured by an appropriate interface, acquires map data and / or route data from an external server or the like, and executes processing such as passing it to the map data acquisition unit 10 and the route data acquisition unit 11.

The storage unit 24 is composed of a non-volatile memory such as a hard disk device and a solid state drive (SSD), and information necessary for each process performed by the facility use area analysis device 100 such as the above-mentioned various information and the operation program of the CPU 26. Remember. The storage unit 24 includes a digital versatile disk (DVD), a compact disk (CD), a magneto-optical disk (MO), a flexible disk (FD), a magnetic tape, an electrically erasable and rewritable read-only memory ( EEPROM), flash memory, etc. may be used. Further, the storage unit 24 includes a random access memory (RAM) that mainly functions as a work area of the CPU 26, and a read-only memory (ROM) that stores a control program such as a BIOS and other data used by the CPU 26. Suitable.

FIG. 2 shows an explanatory diagram of an operation example of the facility use area analyzer 100. In the example of FIG. 2, one regional base 28 such as a train station and one target facility 30 are shown, and the main roads within the target range O of the facility use area analysis including these are shown by lines. Here, it is preferable that the target range O is, for example, the area around the candidate site for opening a store, and the range (within walking / bicycle range) where the station serving as the regional base 28 is the nearest station. Further, a predetermined range A from the target facility 30 set by the route data determination unit 14 is represented by a circle having a radius r. The predetermined range A is not limited to the circular region, and may have an appropriate shape such as a rectangle or an ellipse. Alternatively, as described above, the range of the road where the distance along the road is within a predetermined length may be set by using the road network data starting from the target facility 30. In addition, facing each of the above roads, the residence points of facility users are indicated by black squares (■). Therefore, in the above road, the section between each residential point (■) and the regional base 28 constitutes the route data on the map starting from the residential point of the facility user and ending at the regional base 28. There is. The routes (roads) constituting the route data may overlap with each other in the process of reaching the regional base 28 from each residential point, for example, the road X (road in front of the station) in FIG.

The route data extraction unit 13 extracts the position information of the start point and the end point of the route data acquired by the route data acquisition unit 11 or generated by the route data generation unit 12, and searches for a route using the road network data. Generates the shortest path data connecting the above two points. Next, the route data extraction unit 13 calculates the distance between the route data and the generated shortest route data, and extracts the route data whose difference is within a predetermined threshold value. In the example of FIG. 2, the shortest route data from each residential point in the area of C1 to the regional base 28 is shown by the route a1 displayed on the road of FIG. 2, and the other route data is shown by the routes a2 and a3. Shown. In this case, the above difference calculated for the route a2 is within a predetermined threshold value, and the above difference calculated for the route a3 exceeds a predetermined threshold value. The route data extraction unit 13 extracts the route a2 and stores it in the storage unit 24.

In the area of C2, the route b is shown as the route data from each residential point to the regional base 28, and in the area of C3, the route c is shown as the route data from each residential point to the regional base 28. It is the shortest route to the base 28, and the route data of each route is stored in the storage unit 24. Further, in the area of C4, the shortest route from each residential point to the regional base 28 is shown by the route d, but the route e that joins the route c after branching from the middle of the route d and reaches the regional base 28. Also exists. In this case, the difference in the distance between the route e and the shortest route d exceeds a predetermined threshold value, and the route data of the route e is not stored in the storage unit 24.

The route data determination unit 14 reads the route data extracted by the route data extraction unit 13 from the storage unit 24. Further, the route data determination unit 14 generates a predetermined range A from the target facility 30.

Next, the route data determination unit 14 determines whether or not the route as the route data read from the storage unit 24 passes within the predetermined range A from the target facility 30, and uses the route through the facility. Judged as route data. In the example of FIG. 2, since the routes a2, b, and c pass within the predetermined range A, it is determined to be the facility use route data. The above-mentioned route e also merges with the route c and passes through the predetermined range A, but the difference in distance from the shortest route exceeds the predetermined threshold value, and the route data extraction unit 13 extracts the route e. Since it has not been done, it will not be judged as facility use route data.

The residence point determination unit 16 determines that the residence point of the facility user, which is the starting point of each of the routes a2, b, and c determined to be the facility use route data, is the user residence point of the target facility 30. The facility use area generation unit 18 generates the set of user residence points as the facility use area of the target facility 30. In the example of FIG. 2, three sets (areas) C1, C2, and C3 of the residential points (■) facing the routes a2, b, and c correspond to the facility use area. In C1, the route data of the route a2 is determined to be the facility use route data. Further, as shown in FIG. 2, when the branch roads a4 and a5 are connected to the route a2 and the branch road b1 is connected to the route b, the branch road is also used as a part of the respective routes a2 and b. It is preferable to generate a facility use area.

The facility use area generation unit 18 is a range of the residence points determined as the user residence points of the target facility 30 in addition to the set (areas) C1, C2, and C3 of the residence points generated as the facility use area. The entire range generated by combining the above may be used as the facility use area D of the target facility 30.

If the route data generation unit 12 generates route data (facility use route data) that reaches the regional base from the residential point via the target facility or within a predetermined range, the relevant route data generation unit 12 is applicable. If the route data is extracted by the route data extraction unit 13, the residence point determination unit 16 determines that the residence point of the facility user, which is the starting point of the route data, is the user residence point of the target facility 30. can do. In this case, the determination process of the route data determination unit 14 may not be performed.

In the example of FIG. 2 described above, it is assumed that each route is moved on foot, but the present embodiment is not limited to this, and the present embodiment can be applied even if the above-mentioned transportation means is replaced with a car or a bicycle. Is. When a car is used as a means of transportation, in addition to using a simple distance, it is also possible to apply the use of travel time in consideration of traffic congestion and the reflection of traffic regulations such as one-way traffic.

In addition, a fixed-route bus may be used together as part of the walking movement from the place of residence to the regional base. When using a fixed-route bus, the available target facilities are the route data connecting the residential base and the regional base, excluding the boarding section of the fixed-route bus, between the residential point and the boarding bus stop, and the getting-off bus stop and the regional base. Limited to facilities located in between. Therefore, the determination process of the route data determination unit 14 targets only the above section of the route data.

FIG. 3 shows a flow chart of an operation example of the facility use area analyzer 100 according to the embodiment. In FIG. 3, the map data acquisition unit 10 acquires the map data necessary for the facility use area analysis and stores it in the storage unit 24 (S1).

The route data acquisition unit 11 confirms the existence of route data on the map starting from the facility user's residence point and ending at the regional base within the target range of the facility use area analysis (S2). When the route data exists in an external server or the like (S2-Y), the route data is acquired and stored in the storage unit 24 (S6). If the route data does not exist (S2-N), the process proceeds to the generation process of the route data after S3.

When the route data does not exist (S2-N), the route data generation unit 12 generates the route data. First, one or more resident information is read from the map data stored in the storage unit 24. When the resident information is the address information of the resident, the residence point data converted into the position information on the map such as latitude and longitude is generated by using the address matching which is a known technique based on the address information. If the resident information is location information such as the latitude and longitude of the place of residence, it will be used as the residence point data as it is. If the resident information is statistical data for each polygon shape that has an indefinite shape such as a mesh form, a town street, a district, or a statistical survey area, for example, a center of gravity point is generated for the polygon data. The position information such as the latitude and longitude of the point is used as the dwelling point data (S3).

Next, the route data generation unit 12 reads out the data of the regional base including the location information of the regional base from the map data stored in the storage unit 24. For example, when there are multiple regional bases, such as when the regional base is the exit of the nearest station based on the instruction information input by the operator, a straight line is applied to each residence point data generated in step S3. Assign the closest regional locations using distance or road distance, respectively. Further, regional bases may be assigned by reflecting a predetermined weighting coefficient or the like according to the number of passengers getting on and off the station, the degree of commercial agglomeration, or the like. For example, for a regional base of a station with a large number of passengers, the actual distance may be subtracted by multiplying the distance between the residential point and the regional base by a coefficient of less than 1, and the regional base to be assigned may be adjusted. If there is only one regional base within the scope of facility use area analysis, one regional base is assigned to all residential point data. Further, a plurality of regional bases may be assigned to one residence point (S4).

The route data generation unit 12 reads out the road network data from the map data stored in the storage unit 24, performs a route search which is a known technique using the road network data, and performs a route search which is a known technique, and the position of the residence point data (facility user). The route data is generated starting from the place of residence) and ending at the position of the regional base assigned to the place of residence. The above processing is executed for all the dwelling points, a route to one or a plurality of regional bases assigned to the dwelling point data is generated, and is stored in the storage unit 24 (S5).

The generated route data is preferably the shortest route connecting the residential point and the regional base, but it does not necessarily have to be the shortest route, and a plurality of route data may be generated. For example, as route data that reads out the location information of the target facility from the map data stored in the storage unit 24 and reaches the regional base from the residential point via the target facility or passing through the predetermined range. May be good. In addition, route data may be generated for each target facility via the target facility or within the predetermined range.

The route data extraction unit 13 reads the acquired or generated route data from the storage unit 24, extracts the position information of the start point and the end point from the read route data, and performs the route search using the road network data to perform the above 2 Generate the shortest path data connecting points. Next, the difference in the distance between the acquired or generated route data and the shortest route data is calculated. It is determined whether or not the difference in the calculated distance exceeds a predetermined threshold value, and the route data within the range of the predetermined threshold value is extracted and stored in the storage unit 24 (S7).

The route data determination unit 14 sets a predetermined range of the target facility. First, the position information of all the target facilities is read from the map data stored in the storage unit 24, and a circular shape having a predetermined radius with the position information as the center point is generated on the map. In addition, using road network data instead of a circular shape, the range of roads whose distance along the road is within a predetermined length (constant road distance) is extracted from the location information of the target facility as the starting point. May be good. The predetermined radius or the range of the road can be set in advance by the operator. The above processing is executed for all the target facilities, and a circular shape or a range of a certain road distance is generated and stored in the storage unit 24 (S8).

The route data determination unit 14 determines whether or not the route data extracted by the route data extraction unit 13 of S7 passes within the circular shape or a certain road distance from the target facility generated in S8. , When passing, it is determined that the route data is the facility use route data of the target facility (S9). For each target facility, route data passing within the above range may be extracted, and the route data may be determined as facility use route data of the target facility. The determination result is stored in the storage unit 24.

Here, when the route data created by the route data generation unit 12 reaches the regional base from the residential point via the target facility or within the above-mentioned predetermined range, these route data are the target facility. Can be used as facility use route data of the target facility only by being extracted by the route data extraction unit 13 without performing the processing of S8 and S9 in the route data determination unit 14. ..

The residence point determination unit 16 determines for each target facility by the route data determination unit 14, and / or the route data generation unit 12 passes through the target facility from the residence point or within the predetermined range. Then, the facility use route data of the target facility generated as the route data to reach the regional base is read out from the storage unit 24, and the residence point of the facility user who is the starting point of the facility use route data is set to the above-mentioned target facility. It is determined as a user's residence point (S10). The user's residence point of the determination result is stored in the storage unit 24.

The facility use area generation unit 18 reads out the user residence point of the target facility determined by the residence point determination unit 16 from the storage unit 24, and sets the set of the user residence points in the area where the user of the target facility resides. Generated as a facility use area of the target facility indicating that it exists. The range is within the outer circumference where the user's residence point exists, and that range is the facility use area of the target facility. If the residence point of the facility user is area information, the area where the area is combined is used as the facility use area of the target facility. A facility use area is generated for all target facilities (S11). Further, the resident information is read from the storage unit 24, the number of residents is totaled from the generated resident information in the facility use area of the target facility, and the number of users of the target facility is estimated. The facility use area of the determination result and the estimation result of the number of users of the target facility are stored in the storage unit 24.

As for the facility use area, the same place may be included in the facility use area of a plurality of target facilities. In that case, the overlapping state may be made, the target facility near the regional base may be given priority as the facility use area, or the target facility near the residential point may be given priority as the facility use area.

Further, an upper limit may be set in the range of the facility use area. Depending on the type of target facility, the target facility located far from the residence point may not be available, so a predetermined upper limit is set for the distance between the target facility and the residence point, and the user residence point exceeding that distance is set. May be excluded. The distance between the user's residence point determined by the residence point determination unit 16 and the target facility is calculated, and if the distance exceeds a predetermined threshold value, the user's residence point is excluded from the target range for generating the facility use area. do. Alternatively, if the above applies, the residence point determination unit 16 may not determine the user residence point from the beginning.
