Description

  The present invention relates to a road planning support program and a road planning support device, and more particularly, to a road planning support program and a road planning support device that support calculation of negotiation prospects regarding land acquisition related to road planning.

  In the planned road project led by the government, the project goes to the project decision stage where the project is started through the plan decision stage in which a road plan such as laying a new road or expanding an existing road is created. A planned road refers to a road that is the subject of such administrative work. At the project decision stage, negotiations for expropriation of the land on the planned road began, and the land included in the planned road was divided based on the registry map and area survey map managed by the registry office. A compensation amount is calculated as compensation.

  By the way, while the planned road map is a general residence display, the registry map of the registry office is managed by lot number. For this reason, after overlaying the planned road map of the residential display and the registry map of the lot number display and reflecting the planned road on the registry map, search for the brushes to be expropriated and process the separation, and calculate the compensation money. It must be made.

  With regard to the map of house display and the map of lot number display, there has been proposed a house / lot number display method capable of displaying the map by converting the coordinate system and unit of the map of the house display and the lot number display and overlaying them (for example, , See Patent Document 1).

Therefore, using such a method, the map of the planned road and the registry map are overlaid, and after reflecting the planned road on the registry map, the target brush included in the planned road is detected manually, and the dividing process is performed. I went and calculated the compensation amount.
JP 2002-139993 A (paragraph numbers [0011] to [0030], FIG. 1)

  However, there is a problem that it is not sufficient to simply calculate the compensation amount for the land to be taken apart as the compensation amount that accounts for the majority of the land acquisition cost for the planned road. In particular, when a building is built on the target land, the following problems arise.

  First, if a part of the land owned is scraped, the building coverage ratio (1st floor area / land area) or floor area ratio (total area of the building / land area) is the standard for the land excluding the expropriation part. May fall below the value. In this case, since the entire building needs to be demolished, a building demolition cost, a new building cost, etc. are in addition to the cost of the land to be expropriated, and the compensation amount also increases. In addition, since the building coverage ratio and floor area ratio are determined for each region, whether or not dismantling is necessary must be individually examined for each region.

  Second, there may be a building on the dividing line that separates the land to be expropriated from the remaining land. In this case as well, the entire building must be dismantled, and the same costs as above are added, so the compensation amount must be calculated separately.

  Thirdly, the land excluding the expropriated portion is narrowed by the pen, and the asset value may be lost. Conventionally, the remaining land was not covered by compensation, but if the asset value of the remaining land is lost, the owner may seek some compensation and there is a risk that negotiations will be prolonged. This problem also occurs when there are no buildings on the land.

  Thus, it is not enough to calculate the compensation amount for the land related to the planned road, but it has to be calculated taking into account various other factors. In the above case, it is not easy to obtain the consent of the target person, and there is a possibility that the negotiation period will be prolonged.

  However, although a computer can be used for partial processing such as map superposition as described above, there is no device that supports the entire processing. As a result, there was a tendency for the amount of compensation to be larger than expected and the acquisition period to be longer.

  For this reason, there is a demand for a road planning support device that facilitates the calculation of negotiation prospects regarding land acquisition related to the planned road. With such a road planning support device, for example, if the compensation amount can be calculated and the problem area can be examined before the planning decision stage, the compensation amount can be minimized and the acquisition period can be shortened. Can support the planning of the planned road.

  The present invention has been made in view of the above points, and an object thereof is to provide a road planning support program and a road planning support device that facilitate the calculation of negotiation prospects regarding land acquisition related to a planned road.

  In order to solve the above problem, the computer acquires the first map information stored in the first storage means for storing the first map information in which information indicating the area of the planned road on the map is registered. Second storage for storing acquisition means, second map information in which information indicating the area of the brush on the map is registered, information indicating the area on the map of the building corresponding to the brush, and the total floor area of the building The second map information stored in the means is acquired, and a brush whose at least a part of the area overlaps the area of the planned road is searched from the second map information based on the first and second map information. The brush means is updated so as not to overlap the area of the planned road based on the information indicating the area overlapping the area of the planned road of the brush searched by the search means, and stored in the second storage means Area of the building corresponding to the written brush It is determined whether the area of the building fits within the updated brush area based on the information shown, and if it does not fit, the updating means for determining that the building is to be demolished, the land area, and the price according to the area of the building Based on the price information stored in the third storage means for storing the registered price information, an amount corresponding to the area of the portion of the brush that overlaps the area of the planned road is calculated, and the updating means When it is determined that the building corresponding to the brush is to be dismantled, calculation means for calculating the amount by adding an amount corresponding to the total floor area of the building stored in the second storage means based on the price information A road plan that functions as output means for displaying on a display device image information indicating the magnitude of the amount of money calculated by the calculating means on a map image information based on the second map information. Branch Program is provided.

  Further, in order to solve the above-mentioned problem, the acquisition of acquiring the first map information stored in the first storage means for storing the first map information in which the information indicating the area of the planned road on the map is registered is acquired. And a second memory for storing information indicating the area of the brush on the map, information indicating the area on the map of the building corresponding to the brush, and the total floor area of the building The second map information stored in the means is acquired, and a brush whose at least a part of the area overlaps the area of the planned road is searched from the second map information based on the first and second map information. The brush area is updated so as not to overlap the area of the planned road based on information indicating a search means and an area overlapping with the area of the planned road of the brush searched by the search means, and the second storage means Indicates the area of the building corresponding to the stored brush Based on the information, it is determined whether the area of the building fits within the area of the brush after the update. Based on the price information stored in the third storage means for storing the registered price information, an amount corresponding to the area of the portion of the brush that overlaps the area of the planned road is calculated, and the updating means When it is determined that the building corresponding to the brush is to be dismantled, calculation means for calculating the amount by adding an amount corresponding to the total floor area of the building stored in the second storage means based on the price information And output means for displaying on the display device the image information indicating the amount of money calculated by the calculating means on the image information of the map based on the second map information. Road planning support device It is provided.

In the present invention, after reflecting the planned road figure on the registry map, it is determined whether or not the building needs to be demolished by dividing it. Add up to calculate the compensation amount for the target brush. And the image information which shows the magnitude | size of compensation amount is set on the map which shows the state after a division, and a negotiation prospect map is produced.

In this way, since the compensation amount is calculated by automatically taking into account factors such as the necessity of building dismantling, there is an advantage that the cost required for negotiation can be calculated accurately and easily. In addition, since image information indicating the amount of compensation is displayed at the time of output, it is possible to easily estimate the acquisition period as information indicating the degree of difficulty of negotiation negotiation.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the concept of the invention applied to the embodiment will be described, and then the specific contents of the embodiment will be described.
FIG. 1 is a conceptual diagram of the invention applied to the embodiment.

  The road planning support apparatus 1 according to the present invention includes road information acquisition means 1a, target brush search means 1b, splitting means 1c, compensation amount calculation means 1d, negotiation prospect output means 1e, and brush management information (storage means) 1f. Further, it is possible to connect to road-related information (storage means) 2a, registry office-related information (storage means) 2b, and land / building related information (storage means) 2c, and to read information stored in the respective storage means.

  Here, the road related information (storage means) 2a is storage means for storing road information, road maps, and the like regarding the planned road and the current road. The planned road is a road that is planned to be constructed, whereas the current road is an existing road described in a road map and a registry map. The registry related information (storage unit) 2b is a storage unit that stores a map, a land survey map, a building drawing, a registration date and time, etc., related to real estate owned by the registry. The registration office refers to the Legal Affairs Bureau, the Legal Affairs Bureau, its branches / branch offices, and is used here mainly to mean the registration of real estate registration information (registration office (Ministry of Justice) map, land survey map, building drawings, etc.). . Land / building-related information (memory means) 2c is information on land and buildings excluding registry information. For example, the building coverage ratio and floor area standard for a given area, land transaction price, building price, and narrow land judgment standard Storage means for storing information such as.

  When the road information acquisition means 1a inputs the designation information of the planned road to be investigated such as the road number and the route name, the road information acquisition means 1a searches the road related information (storage means) 2a using this as a search key, and the road map relating to the target planned road. Get road related information including This road map is a map of residence display. When the planned road is an extension of the current road, road-related information regarding the current road is acquired in the same manner, and the width increment is calculated from the width of the planned road and the width of the current road.

  The target brush search unit 1b acquires a registry map of the area to be investigated from the registry related information (storage unit) 2b. Since this registry map is a lot number display, it is superimposed with the road map of the residence display acquired by the road information acquisition means 1a, and the current road pattern and the planned planned road pattern on the road map are reflected on the registry map. Let Then, a brush that at least partially overlaps the area of the planned road graphic excluding the current road graphic is searched from the registry map where the planned road graphic is set. The retrieved brush sets, as the target brush, information identifying the brush such as a lot number in the brush management information and stores it in the brush management information (storage means) 1f. At this time, if necessary, the planned road figure is corrected from the width increment based on the actual planned value. Then, the distance between the boundary line of the planned road figure that becomes a parting line for the brush pattern of the target brush and the brush boundary line of the brush pattern of the target brush is calculated, and the movement distance of the brush line is stored in the brush management information (storage means) 1f. Store.

  The splitting means 1c performs the splitting for each target brush searched by the target brush searching means 1b, and determines whether the building dismantling is required by this splitting. First, read the brush management information, get the area survey map of the brush from the lot number etc. of the target brush registered in the brush management information, draw the pen line on the area survey map based on the movement distance of the brush border line Make a pen. Next, the land area of the expropriated portion on the current road side divided by the stroke line is calculated and set in the brush management information. Further, the area of the land excluding the expropriated portion is calculated, and the building coverage ratio and the floor area ratio after the separation are calculated from the building area and the total floor area of the building drawing information of the target brush. Then, the building coverage ratio and the floor area ratio set in the area of the target brush are acquired, and it is determined whether or not the building coverage ratio and the floor area ratio after the separation satisfy the standard, based on the acquired building coverage ratio and the floor area ratio. If the standard is not satisfied, the building dismantling requirement is set in the brush management information. In addition, it is determined whether or not a building exists on the dividing line, and if it exists, the building dismantling point is set in the brush management information. Further, if necessary, the same determination is made for matters that may affect the compensation amount at the time of negotiation and the negotiation period, and the result is set in the brush management information. For example, it is determined whether or not a situation occurs in which the area of the land excluding the expropriation portion becomes narrow and the utility value is lost, and the result is set in the brush management information. It should be noted that the determination regarding items related to the compensation amount, such as the necessity of building dismantling based on the building coverage ratio and the floor area ratio, may be performed by the compensation amount calculating means 1d at the subsequent stage.

  The compensation amount calculation means 1d calculates the compensation amount of the target brush based on the brush management information set by the brush writing means 1c, and sets it in the brush management information. The transaction price information of the land in the corresponding area is read from the land / building related information (storage means) 2c, and the compensation amount is calculated from the land area to be expropriated set in the brush management information. Then, if the building dismantling requirement is set in the brush management information, the building price standard information is read from the land / building related information (storage means) 2c, the reference value of the approximate building compensation amount is obtained, and the building dismantling is obtained. The building compensation amount is calculated from the building area and total floor area used in the determination of necessity. In addition, when the necessity determination of building dismantling is not performed in the dividing means 1c, determination is performed before calculation of a building compensation amount. The compensation amount for land and the compensation amount for buildings obtained as described above are added together to obtain the compensation amount for the target brush. Further, when compensation amounts for other factors are necessary, these compensation amounts are also added to calculate the compensation amount for the target brush. For example, if the remaining land is narrow, if the compensation fee is paid, the corresponding compensation cost is added according to the result of the narrow land determination. The finally calculated compensation amount is set in the brush management information.

  Based on the brush management information, the negotiation prospect output means 1e displays the difficulty level of the negotiation prospect according to the compensation amount at the corresponding position on the registry map where the stroke boundary line created by the dividing means 1c is drawn. Add an icon to indicate. For example, by defining a money icon that changes in size and number according to the amount, and setting an icon according to the compensation amount of the target brush on the map, you can see the amount of compensation for the target brush at a glance Realize the display. In addition, an icon indicating the necessity of building demolition is assigned to a brush that requires building demolition and displayed.

The brush management information (storage unit) 1f is a storage unit that stores brush management information related to the target brush searched by the target brush search unit 1b.
Each processing unit described above realizes its function by the computer executing the road planning support program.

The operation of the road planning support apparatus 1 will be described.
When the road number for designating the planned road to be surveyed is input to the road planning support device 1, the road information acquisition means 1a reads the road map and road attributes (width and road name) for the planned road corresponding to the designated road number. , Type, etc.) are read from the road related information (storage means) 2a. The target brush search means 1b reads the registry map from the registry related information (storage means) 2b, superimposes the road map read by the road information acquisition means 1a and the registry map, and creates a planned road figure on the road map. Is reflected on the registry map. Overlaying the road map with residence display and the registry map with lot number display sets multiple reference points that are clearly the same location, and corrects the coordinate values of either map so that these reference points match. Do it. Furthermore, the target brush search means 1b searches for a brush for expropriation based on the planned road figure on the registry map. That is, all the brush figures included between the current road brush border and the planned road brush border are extracted. Then, the stroke management distance is set in the brush management information, which is the difference between the information identifying the extracted target brush, such as the lot number, and the stroke line of the current road and the stroke line of the planned road.

  The dividing means 1c reads out the brush management information for each target brush, draws a dividing line on the area survey map of the target brush based on the movement distance of the boundary line, and performs the dividing, and the land of the expropriation part on the current road side The area is calculated and set in the brush management information. In addition, the land area excluding the expropriated portion is calculated, and the building coverage ratio and floor area ratio after partitioning are calculated from the building area and total floor area of the building drawing information of the target brush, and the building area ratio and floor area ratio of the target area are calculated. Determine whether the criteria are met. If the standard is not satisfied, the building dismantling requirement is set in the brush management information. Further, it is determined whether or not a building exists on the dividing line, and if it exists, the building disassembly requirement is set in the brush management information. Next, the compensation amount calculation means 1d calculates the compensation amount for the collection place of the brush from the land area to be collected set in the brush management information and the transaction price of the land / building related information (storage means) 2c. . Further, when the building dismantling requirement is set in the brush management information, an approximate reference value of the building compensation amount is acquired, and the building compensation amount is calculated from the building area and the total floor area of the building. Then, the compensation amount for the land and building is added together to obtain the compensation amount for the target brush. Further, when compensation amounts for other factors are necessary, these compensation amounts are also added to calculate the compensation amount for the target brush.

  Based on the brush management information, the negotiation prospect output means 1e adds and displays an icon indicating the difficulty level of the negotiation prospect according to the compensation amount at the corresponding position on the registry map where the stroke line after the separation is drawn. .

  In this way, when the planned road to be surveyed is designated, the designated road figure on the registry map is reflected, and then a pen is drawn to determine the necessity of building dismantling, etc. When the building dismantling is required together with the amount, the cost is added to calculate the compensation amount for the target brush, so the cost required for negotiation can be calculated accurately and easily.

  In addition, the difficulty level of the negotiation prospect according to the compensation amount is indicated by an icon, and this icon is displayed corresponding to the brush on the negotiation prospect map where the planned road is drawn, so that the acquisition period can be easily predicted. Will be able to.

Hereinafter, an embodiment will be described in detail with reference to the drawings, taking as an example the case of calculating a negotiation probability for a road plan for expanding the width of an existing road.

Hereinafter, the processing operation of the road planning support apparatus 100 having such a configuration will be described. First, the flow of the entire process will be described, and then each process will be described.
FIG. 16 is a flowchart showing a processing procedure of the road support apparatus according to the present embodiment.

  [Step S01] The designation information (road number, route name, etc.) of the planned road to be investigated is input. The designation information is acquired from the user terminals 500a and 500b connected via the network.

  [Step S02] Based on the designation information acquired in step S01, the road information attribute database 210 and the road / land information map database 220 are searched, and road information attributes and road / land information maps relating to the planned road to be investigated are acquired. Then, based on the obtained road information attribute, the width increase when expanding from the current road to the planned road is calculated.

  [Step S03] The registry map database 310 is searched to obtain a corresponding registry map, and is superimposed on the road / land information map acquired in step S02. If necessary, correct the road figure in increments of width. Then, the road figure to be surveyed is drawn on the registry map, the brush figure in contact with the brush border of the road figure and the affected brush are searched, and all of them are extracted. Also, the movement distance of the brush stroke line is registered in the target brush management work table.

  [Step S04] With respect to the target brush extracted in step S03, a geodetic survey map is extracted from the geodetic survey map database 320, and a pen stroke line is newly drawn to perform a pen stroke process. Further, the building drawing database 330 is searched to acquire the building information of the target brush, and the building coverage ratio and the floor area ratio are calculated with respect to the brush that is not subject to expropriation. The calculated building coverage ratio and floor area ratio are registered in the target brush management work table.

  [Step S05] It is checked whether there is a building on the dividing line of each target brush. That is, the brush figure and the building figure of the target brush divided in step S04 are superimposed, and it is checked whether or not there is an intersection between the dividing line and the building figure, and the brush with the intersection is specified. If there is a building on the dividing line, the building disassembly flag 117e of the corresponding brush is set.

  [Step S06] A compensation amount calculation process is performed based on the target brush management work table to create and output a compensation amount map. The transaction price database 420 is searched, the reference price of the corresponding route is acquired, and the compensation amount of the destination area for the target brush is calculated. Further, the building coverage ratio / floor ratio calculated in step S04 is compared with the reference of the corresponding route extracted from the building coverage ratio / volume ratio reference database 410, and it is determined whether or not building dismantling is necessary. If it is determined that it is necessary and if the building dismantling flag 117e is set in step S05, the compensation amount for the building is calculated with reference to the corresponding data in the building price standard database 430 and the registration database 340. Further, the remaining area is compared with the narrow area determination master table 440, and when it is determined that the area is narrow, the remaining area compensation amount is calculated. These are added together to calculate the total compensation estimate. An icon corresponding to the compensation amount calculated in this way is set on the registry map on which the state after the division is drawn, and a compensation amount map is created and output.

Next, processing in each step will be described in detail.
(1) Road Information Acquisition and Width Increment Calculation Processing The road information acquisition module 112 uses the “road number” or “road name” and “type = current” of the planned road designated as the survey target as road information attributes. The database 210 is searched and the width of the current road is extracted. Subsequently, the road information attribute database 210 is searched using the same “road number” or “road name” and “type = plan” as search keys, and the width of the planned road is extracted. Then, the width increment calculation module 111 calculates the width increment expanded from each width. The calculation is
Width increase = Plan road width-Current road width (1)
Do by. For example, in the case of “C hill line” in FIG. 5, the width increase is 30−19 = 11 m. The road information acquisition module 112 searches the road / land information map database 220 to acquire a road / land information map related to the planned road to be investigated.

(2) Registry Map Information Acquisition and Target Brush Search Process The registry related information acquisition module 114 searches the registry map database 310 and acquires a registry map related to the planned road to be investigated. (1) Although the road / land information map acquired in the road information acquisition process is a residence display as shown in FIG. 6, the registration map is a lot number display as shown in FIG. I do. In the superimposition processing, a plurality of brush boundary points that can be clearly recognized as the same place on both maps are designated as a reference point. For example, a road intersection is designated as the reference point. Then, based on the reference point, the coordinate value of either map is corrected, and the registry map and the road / land information map are superimposed.

FIG. 17 is a diagram showing an overlay process of the road / land information map and the registry map in the target brush search according to the present embodiment.
The figure of the planned road 601c is specified by shifting the boundary line of the current road 601a on the road / land information map 601 by the width increment 601b from the road information attribute data and road / land information map data relating to the road to be investigated. Can do. The road / land information map 601 and the registry map 602 are overlaid as described above. For example, the points T1, T2, T3, T4 that specify the brush figure of the lot number 10 of the registry map 602, and the road -The divisions U1, U2, U3, U4 on the land information map 601 match. Thereby, the planned road figure on the road / land information map 601 can be reflected in the registry map 602.

  FIG. 18 is a diagram showing a registry office map in which the planned road of the present embodiment is reflected. In a map (hereinafter referred to as an overlay map) 603 in which a registry map and a road / land information map are superimposed, a planned road represented by a brush border line TaTc and a brush border line TbTd is drawn on the registry map 602. Is done.

  Hereinafter, the target brush search module 113 searches for a brush related to the planned road based on the overlay map 603. First, all the brushes that touch the current road graphic of the overlay map 603 are extracted. That is, a brush figure that shares at least part of the same brush stroke as the current road figure is searched. In the example of the figure, a lot number 6 sharing the brush border line T5T1, a lot number 10 sharing the brush border line T1T2, a lot number 8 sharing the brush border line T2T7, a lot number 9 sharing the brush border line T14T10, a lot number 7 sharing the brush border line T10T11, And the lot number 11 which shares the brush stroke line T11T21 is searched. The lot number of the searched brush figure is stored in the target brush management work table. This process may be performed when the registry map is acquired. Then, for each retrieved brush, the stroke line that becomes the dividing line is specified from the stroke boundaries TaTc and TbTd of the planned road parallel to the boundary line of the brush that touches. In this case, the one that has an intersection with the brush border constituting the brush is searched. For example, the writing boundary line TbTd is a writing boundary line that becomes the dividing line of the lot number 10, since it has an intersection with the writing line T1T4 of the lot number 10 and T2T3. On the other hand, the writing line TaTc does not have an intersection with all the writing lines of the lot number 10, and therefore, does not become the dividing line of the lot number 10.

  Next, the movement distance of the brush boundary line, that is, the distance between the brush boundary line TaTc or TbTd serving as the dividing line and the brush boundary line shared with the current road is calculated. At this time, the planned road graphic drawn on the overlay map 603 may not match the width increment based on the actual plan obtained from the road information attribute data. Correct to fit. First, the distance between the boundary line that is in contact with all the brushes that are in contact with one side of the road and the stroke line identified by the above processing, that is, the width increment, is calculated, and the average value is calculated. For example, the width increments at lot number 6, lot number 10 and lot number 8 are calculated, and an average value is obtained. Each width increment is obtained by, for example, calculating the distance between the intersection point of the writing line TbTd and the writing line T1T4 and T1. Similarly, the average value of the width increment is calculated for the other (lot number 9, lot number 7, lot number 11). And the average value of the width | variety increment calculated about the stroke line TaTc and the average value of the width | variety increment calculated about the brush stroke line TbTd are added together, and it compares with the width | variety increment obtained from road information attribute data. If they do not match, the average value of the width increment is corrected so as to be the width increment obtained from the road information attribute data.

  For example, it is assumed that the average value of the width increment related to the border line TaTc obtained from the drawing is 12 m, the average value of the width increment related to the brush line TbTd is 10 m, and the planned value is 11 m. The total width increment on the drawing is not 11 m, so correction is performed.

Width increment related to TaTc = 12 m × 11 m / 22 m = 6 m
Width increment related to TbTd = 10 m × 11 m / 22 m = 5 m (2)
Can be calculated. Based on the corrected width increment, the stroke boundaries TaTc and TbTd of the planned road are corrected.

  Furthermore, a brush that is not in contact with the current road but is affected by the expansion of the road is extracted. All brushstrokes included between the stroke boundaries TaTc and TbTd of the planned road corrected by Expression (2) and the stroke boundaries of the current road are extracted. The extracted brush lot number is stored in the lot number 117a of the target brush management work table. In addition, the distance between the brush stroke line and the stroke line of the brush with the corrected brush stroke line as the split stroke line is calculated and stored in the brush stroke moving distance 117b of the target brush management work table. At this time, the brush graphic already extracted as being in contact with the current road overwrites the searched lot number in the lot number 117a of the target brush management work table, and the corresponding width increment value obtained by Expression (2) is used. Stored in the brush stroke moving distance 117b.

(3) Separation processing and building coverage ratio / volume ratio calculation processing The following processing is sequentially performed for all brushes stored in the target brush management work table. First, the building coverage ratio / volume ratio calculation module 115 activates the drawing module 116 to perform a drawing process. The writing module 116 reads each lot number 117a by the registry related information acquisition module 114, searches the lot survey database 320 based on the lot number, and extracts the corresponding lot survey map. Then, the stroke line of the current road is drawn on the land survey map figure, and the stroke line is translated in the direction opposite to the road by the stroke line movement distance 117b of the target brush management work table, and a new stroke line is drawn. create.

An example will be described. FIG. 19 is a diagram showing an example of the setting process of the stroke line in the present embodiment.
In the example shown in the figure, it is assumed that the area survey diagram 610a of the brush of the lot number 10 is retrieved. The lot number 10 is in contact with the current road represented by the lot number B, and has a brush figure drawn by the stroke boundaries T1T2, T2T3, T3T4, and T4T1. First, the current road brush border (TeTf) 611 shared with the brush border T1T2 is drawn on the land survey map 610a.

  In the subsequent separation process, the stroke boundary movement distance 117b of the lot number 10 is extracted from the target brush management work table, in this case, "5m", and the current road boundary line (TeTf) 611 is translated to the position opposite to the road. , A new stroke line (TgTh) 612 is drawn. As a result, a land survey map 610b is created.

Thus, when the separation process is performed, the building coverage ratio / volume ratio calculation module 115 calculates the building coverage ratio and the volume ratio based on the area survey diagram 610b in which the dividing line (TgTh) 612 is drawn. First, the registry related information acquisition module 114 searches the building drawing database 330 based on the lot number 117a stored in the target brush management work table, and extracts the building area and the total floor area. And the area of the remaining land 613 on the opposite side to the road is calculated from the land divided by the dividing line (TgTh) 612, and the building coverage ratio and the floor area ratio are calculated from the extracted building area and total floor area. The building coverage ratio and floor area ratio are
Coverage ratio = building area / land area,
Floor area ratio = total floor area / land area (3)
Is calculated by The calculated building coverage ratio and floor area ratio are stored in the building coverage ratio 117c and the volume ratio 117d of the corresponding brush in the target brush management work table.

(4) Building Search Processing on the Pencil Line The building search module 118 on the pen stroke line sequentially performs the following processing for all the brushes stored in the target brush management work table. First, the building drawing database 330 is searched based on the house number 117a of the target brush management work table, and the building drawing of the target brush is extracted. Further, after reading the area survey map of the corresponding brush divided by the above processing, and converting the coordinates of the extracted building drawing so as to match the area survey map, the building figure is superimposed on the area survey map.

An example will be described. FIG. 20 is a diagram showing an example of a building search process on the stroke line in the present embodiment.
In the example shown in the figure, the building search process is performed based on the land area survey map 610b of the lot number 10 that has been subjected to the separation process. First, the building drawing database 330 is searched, and the building drawing 620 of the lot number 10 is extracted. Then, the coordinates of the building drawing 620 are aligned with the land surveying map 610b, and the building figure of the building drawing 620 is superimposed on the land surveying map 610b.

  It is determined whether or not there is a building on the dividing line based on the composition survey map 630 created in this manner and the composite figure 630 of the building figure. That is, it is checked whether there is an intersection between the stroke line (TgTh) 612 and the building graphic, and if the intersection is detected, it is determined that the building is on the stroke line. In the example shown in the figure, the intersection points 631a and 631b are detected on the dividing line (TgTh) 612, and therefore it is determined that the building “Aoi” of the lot number 10 is on the dividing line (TgTh) 612.

As described above, when an intersection point is detected between the stroke line and the building graphic, the building disassembly flag 117e of the corresponding brush in the target brush management work table is turned on.
(5) Compensation amount calculation processing and compensation amount map output processing The following processing is sequentially performed for all the brushes stored in the target brush management work table. The compensation amount map output module 119 activates the compensation amount calculation module 120 and calculates the compensation amount of the target brush. The compensation amount calculation module 120 searches the transaction price database 420 by the land / building related information acquisition module 121 based on the housing display information associated with the lot number 117a of the target brush, and acquires the reference price of the land on the corresponding route. . Then, the compensation amount is calculated according to the land area of the brush on the side that becomes the road after the division based on the area survey map after the division. The calculated compensation amount of the land to be collected is stored in the compensation amount (land) 117f of the corresponding brush in the target brush management work table.

Next, the land / building related information acquisition module 121 searches the building coverage ratio / flood ratio reference database 410 based on the lot number area extracted in the above processing, and acquires the building coverage ratio and the floor ratio reference of the corresponding area. Then, the building coverage ratio 117c and the volume ratio 117d calculated in the target brush separation process stored in the target brush management work table are read and compared with the reference. If the building coverage ratio and the floor area ratio after the separation process have not reached the standard, the building must be disassembled, so the building disassembly flag 117e of the corresponding brush in the target brush management work table is turned on. With this process, the building dismantling flag 117e is turned on when the building after partitioning does not satisfy the criteria for the building coverage ratio / volume ratio, or exists on the dividing line. The compensation amount calculation module 120 sequentially searches the registration database 340 via the registry office related information acquisition module 114 for the brush whose building dismantling flag 117e is turned on, and extracts the building age and structure of the building. Further, the total floor area of the building is extracted from the building drawing database 330. Further, based on the lot number area, the building price reference database 430 is searched by the land / building related information acquisition module 121 to obtain a transaction price for the floor area, a coefficient corresponding to the building age, and the like. Then, obtain the approximate transaction price (yen / m ² ) from the transaction price (yen / m ² ) per unit of the total floor area for the building, age and structure, and multiply by the total floor area of the building. By doing so, the compensation amount (building) is calculated. The calculated compensation amount of the building is stored in the compensation amount (building) 117g of the corresponding brush in the target brush management work table. Further, the total compensation amount is calculated by adding the compensation amount (land) 117f and the compensation amount (building) 117g, and stored in the compensation amount (total) 117h.

Finally, it is determined whether the land area of the brush (residual land) that remains after the separation is narrow or narrow based on the area survey map after the separation. The compensation amount calculation module 120 detects the area of the remaining land based on the area survey map after the separation, and stores the determination criteria stored in the narrow land determination master table 440 read out via the land / building related information acquisition module 121. Match. When the remaining area corresponds to the determination area of the narrow area determination master table 440, the corresponding price reduction ratio is read and the remaining area compensation amount is calculated. Remaining area compensation amount is
Remaining land compensation amount = [area of applicable brush (remaining land)] x [transaction price retrieved from transaction price database] x [price reduction ratio] (4)
Can be calculated. The calculated residual compensation amount is stored in the residual compensation amount 117i of the target brush management work table.

  Through the above processing, the compensation amount for all brushes is calculated. Subsequently, the compensation amount map output module 119 creates a compensation amount map based on the calculated compensation amount. The compensation amount map is created by setting an icon indicating the degree of difficulty corresponding to the compensation amount on the registry map showing the stroke boundaries after the separation.

An example will be described. FIG. 21 is a diagram showing a display example of the compensation amount map of the present embodiment. The figure is created based on the overlay map 603.
In the figure, a road figure (shaded portion) of the planned road 701 represented by a brush border 702 represented by a solid line, a brush border 703 of a current road represented by a two-dot chain line, and a brush of a lot number in the vicinity of the current road ( The lot numbers 6, 6-1, 7, 8, 9, 10, 11) are displayed. The stroke line (plan road) 702 is a stroke line after the correction is performed.

  A money icon 704, a building dismantling icon 705, and a narrow land icon 706 are set for each brush on the registry map after dividing by such a planned road. The money icon 704 is an icon set at the position of the corresponding brush according to the amount of compensation amount (total) 117h in the target brush management work table. In the example in the figure, one coin represents 10 million yen. ing. For example, the lot number 9 is 20 million yen, and the lot number 7 is 30 million yen. The building dismantling icon 705 is set at a position corresponding to a brush whose building dismantling flag 117e in the target brush management work table is on. In the example of the figure, it can be seen that the building dismantling of the lot number 10 and the lot number 8 is necessary. The narrow land icon 706 is set at a position corresponding to a brush whose remaining area compensation amount 117i of the target brush management work table is not 0. In the example of the figure, it is understood that the lot number 6 is a narrow land, and there is a possibility that 10 million yen may be added as the narrow ground compensation amount.

  As described above, in the embodiment of the present invention, the planned road figure is reflected on the registry map by overlapping the planned road set in the road / land information map with the residence display and the registry map with the lot number display. And specify the target brush. At this time, the planned road figure drawn on the registry map is corrected to match the actual planned value obtained from the road information attribute. This is because the planned road drawn on the drawing may deviate from the width increment based on the actual plan, so the planned road figure on the drawing is corrected to match the actual planned value, The amount of compensation can be estimated more accurately. Based on this map, for each target brush, whether or not a pen line is drawn on the building, whether the building coverage and floor area ratio after the pen meets the standard, and the remaining land is a narrow area where the asset value is reduced Check items that affect the difficulty of negotiation prospects, such as whether or not there is. If the building is on the dividing line, and if the building coverage ratio and floor area ratio after dividing the line do not meet the standards, the building must be dismantled, and the cost for that is added to calculate the compensation amount for the target brush. In addition, when the remaining area is narrow, a remaining area compensation amount that may be added to the compensation amount is calculated. In this way, the compensation amount can be calculated more accurately by adding the compensation amount in consideration of the elements necessary for the acquisition of the land for acquisition.

  In addition, the degree of difficulty of the negotiation estimate according to the compensation amount is indicated by an icon, and this icon is displayed corresponding to the brush on the compensation amount map on which the planned road is drawn, so the size of the compensation amount estimate is accurate and easy As a result, the forecast accuracy of the acquisition period will be improved accordingly.

  For example, in the case of FIG. 21, the approximate amount of compensation can be easily grasped by the money icon 704. Further, the building demolition icon 705 can also grasp a brush and a narrow ground icon 706 that require a building demolition to increase the compensation amount. In this way, since elements that affect negotiation prospects are visually displayed, it is possible to easily predict the negotiation period.

  Furthermore, since the road planning support device can automatically perform processing up to the output of the compensation amount map, the optimum planned road can be determined by outputting several compensation amount maps by changing the conditions of the planned road. Can do. For example, in the example of FIG. 21, the dismantling of the building is required at the lot number 8 and the lot number 10, and the lot number 6 is a narrow land, so the planned road is narrowed or the position is shifted to the lot numbers 9, 7, and 11 side. A compensation amount map can be created and compared with the initial compensation amount map. By shifting the location of the planned road, the total amount of compensation can be reduced if the dismantling of the lot numbers 10 and 8 is not necessary.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the road planning support apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Examples of the optical disc include a DVD (Digital Versatile Disc), a DVD-RAM (Random Access Memory), a CD-ROM (Compact Disc Read Only Memory), and a CD-R (Recordable) / RW (ReWritable). Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, portable recording media such as a DVD and a CD-ROM in which the program is recorded are sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. Further, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.
