Summary of the Invention

Problems to be Solved by the Invention

[0005] In the conventional technology, based on the deterioration prediction of assets, by creating a repair plan with the recommended repair work timing grouped for each of a plurality of assets close to the construction location, it is possible to obtain a cost reduction effect of simultaneously repairing a plurality of assets by reducing man-hours. However, when the asset management agencies are different, there is a possibility that schedule adjustment may occur due to unexpected overlapping of construction work by the persons in charge. For example, after completing road construction first, when the construction of a water pipe buried underground of the road is carried out by a management agency different from the road construction. As a result, in order to construct the underground water pipe, it is necessary to excavate a sound road that has just been repaired, and there is a problem of uneconomy due to overlapping construction work.

[0006] The present disclosure has been made to solve the above problems, and an object thereof is to provide a repair plan creation device, a repair plan support system, a repair plan creation support method, and a repair plan creation support program that can create a repair plan considering the influence of asset construction on the surroundings and other assets located near the asset to be constructed.

Means for Solving the Problems

[0007] In the present disclosure, assets such as roads, bridges, or tunnels that have been considered in the conventional technology are regarded as road-related assets, and assets such as water pipes, communication cables, power cables, or gas pipes accommodated underground of the road are regarded as occupied properties.

[0008] The repair plan creation device according to the present disclosure includes a communication unit that acquires construction information of road-related assets and construction information of occupied properties, and extracts a construction area overlap area where the construction areas of the road-related assets and the occupied properties overlap from the construction information of the road-related assets and the construction information of the occupied properties acquired by the communication unit, and a processing unit that calculates the construction timing of the road-related assets and the occupied properties belonging to the construction area overlap area.

[0009] The repair plan creation support system according to the present disclosure includes a management device that acquires construction information of road assets and construction information of occupied properties, and from the construction information of road assets and the construction information of occupied properties acquired by the management device, it extracts a construction area overlapping area where the construction areas of road assets and occupied properties overlap, and has a processing unit that calculates the construction times of road assets and occupied properties belonging to the construction area overlapping area.

[0010] The repair plan creation method according to the present disclosure includes a step of acquiring construction information of road assets and construction information of occupied properties, a step of extracting a construction area overlapping area where the construction areas of road assets and occupied properties overlap from the acquired construction information of road assets and the construction information of occupied properties, and a step of calculating the construction times of road assets and occupied properties belonging to the construction area overlapping area.

[0011] The repair plan creation program according to the present disclosure causes a computer to execute a step of acquiring construction information of road assets and construction information of occupied properties, a step of extracting a construction area overlapping area where the construction areas of road assets and occupied properties overlap from the acquired construction information of road assets and the construction information of occupied properties, and a step of calculating the construction times of road assets and occupied properties belonging to the construction area overlapping area.

Effect of the Invention

[0012] According to the present disclosure, by considering in advance the construction information of road assets and the construction information of occupied properties, an appropriate repair plan for the assets can be created. Based on the created repair plan, the user can formulate a repair plan that can be constructed in the same period, so that efficient and economical construction can be carried out.

[0015] Embodiment 1. <Configuration of Repair Plan Support System 100> FIG. 1 is a diagram showing an example of the configuration of a repair plan support system 100 according to Embodiment 1. As shown in FIG. 1, the repair plan support system 100 according to Embodiment 1 includes a management device 1 and a repair plan creation device 2. The management device 1 and the repair plan creation device 2 are communicably connected to each other via a network 3. The network 3 is, for example, a WAN (Wide Area Network) such as the Internet or a LAN (Local Area Network).

[0016] The management device 1 is, for example, a computer installed in an office such as a road administrator or a public utility, and centrally manages information on road-related assets and occupied properties held. Road-related assets are, for example, roads, bridges, or tunnels. Also, occupied properties are, for example, water pipes, gas pipes, or communication cables. The above-mentioned road-related assets and occupied properties are not limited to these. The management device 1 may be provided on a server outside the office or in the cloud regardless of being installed within the office.

[0017] The repair plan creation device 2 is a computer installed in an office of, for example, a road administrator or a public utility company, and supports the creation of a repair plan by a user of the repair plan support system. The repair plan is a plan for maintaining and managing a plurality of road-related assets and occupied properties. The repair plan creation device 2 is not limited to being installed within the office, and may be provided on a server outside the office or in the cloud.

[0018] The users of the repair plan support system are, for example, road administrators and public utility companies that maintain and manage the above-mentioned plurality of road-related assets and occupied properties, but are not limited thereto. Hereinafter, the users of the repair plan support system may sometimes be simply referred to as "users". Also, the road-related assets and occupied properties may sometimes be collectively referred to as "assets".

[0019] The management device 1 includes a communication unit 10, a processing unit 11, an input unit 12, and an output unit 13. Also, a display device 14 and an input device 15 are externally connected to the management device 1. The repair plan creation device 2 includes a communication unit 20, a processing unit 21, and a storage unit 22.

[0020] The communication units 10 and 20 are interfaces for connecting to the network 3 and transmitting and receiving information to and from each other via the network 3, and are, for example, LAN terminals. The communication units 10 and 20 are not limited to LAN terminals which are wired network terminals, and may perform wireless communication, for example, by a wireless LAN method.

[0021] The input unit 12 in the management device 1 is an input interface for inputting user instructions and data from outside the management device 1, and is, for example, a USB terminal. The input unit 12 is connected to the input device 15 by a USB cable, and the processing unit 11 receives user instructions from the input device 15. Here, the input device 15 may be any device that receives some input from the user, and is, for example, a keyboard, a mouse, a touch panel, etc. The connection method between the input device 15 and the input unit 12 may be either wireless or wired. In the case of wireless, a communication standard such as Bluetooth becomes the input interface.

[0022] The processing unit 11 in the management device 1 is a processor such as a CPU, and is connected to the communication unit 10, the input unit 12, and the output unit 13. When there is a user operation on the input unit 12, the processing unit 11 processes the input information and transmits it to the repair plan creation device 2 via the communication unit 10.

[0023] The output unit 13 is an output interface for outputting data acquired by the processing unit 11, calculation results obtained by calculation, etc. outside the management device 1, and examples include an HDMI terminal (HDMI is a registered trademark), a DVI terminal, and a D-Sub terminal. The output unit 13 is connected to the display device 14 by various cables, and the processing unit 11 displays various information on the display device 14 via the output unit 13.

[0024] The display device 14 is a device for receiving and displaying the information transmitted by the repair plan creation device 2, and examples include a liquid crystal display, a plasma display, an organic EL display, a smartphone, and a portable tablet device. Also, in a road management office, since the maintenance and management of road-related assets and occupied properties are performed by a plurality of road administrators, the display device 14 may be a large multi-screen system combining a plurality of displays to improve visibility.

[0025] The processing unit 21 of the repair plan creation device 2 is a processor such as a CPU, and is connected to the communication unit 20 and the storage unit 22. The processing unit 21 executes the repair plan creation program installed in the storage unit 22, controls the operations of the communication unit 20 and the storage unit 22, and executes arithmetic processing and the like.

[0026] The processing unit 21 of the present embodiment, as a repair plan creation program, extracts a construction area overlap area where the construction areas of the road system assets and the occupied properties overlap from the construction information of the road system assets acquired from the management device 1 and the construction information of the occupied properties. It includes a construction area extraction unit 21a1, a constructible time extraction unit 21a2 that extracts the constructible times of the road system assets and the occupied properties within the extracted construction area overlap area, a simultaneous construction feasibility determination unit 21a3 that determines whether the road system assets and the occupied properties within the construction area overlap area can be constructed simultaneously, and a construction time output unit 21a4 that calculates the optimal construction times of the road system assets and the occupied properties in consideration of economic factors such as construction costs and construction periods.

[0027] The storage unit 22 is a storage medium that stores the repair plan creation program and various data executed by the processing unit 21. Examples include a hard disk drive (HDD), a solid state drive (SDD), a USB flash memory, an SD card, etc. In the present embodiment, the storage unit 22 is provided inside the repair plan creation device 2, but it may also be provided externally.

[0028] The storage unit 22 stores information on assets owned by road administrators and public utility operators in the asset database 22a. Fig. 2 shows the data structure of the road system asset information data table 22a1 held by the asset database 22a. As shown in Fig. 2, the repair plan creation device 2 associates and stores, for each asset ID which is a running number, the road type representing the type of the road system asset, the route number of the road, the KP (kilometer post) which is a distance standard representing the distance from the starting point of the road, the section distance where the road system asset is located, information on whether the road is an uphill lane or a downhill lane, and the number of lanes of the road, which are acquired from the management device 1.

[0029] Fig. 3 shows the data structure of the occupied property information data table 22a2 held by the asset database 22a. As shown in Fig. 3, the repair plan creation device 2 associates and stores, for each property ID which is a running number, the property type indicating the type of the occupied property, the related asset ID indicating which road system asset the occupied property is installed alongside, and the management office code indicating the office that manages the occupied property, which are acquired from the management device 1.

[0030] Figure 4 shows the data structure of the deterioration prediction information data table 22a3 held in the asset database 22a. As shown in Figure 4, the repair plan creation device 2 stores, for each prediction ID which is a running number, the target type indicating whether it refers to a road asset or an occupied property, the target ID specifying which asset ID or property ID of the road asset and the occupied property to refer to, the deterioration period prediction shown using the evaluation rank obtained by evaluating the deterioration prediction of the asset for each period, and the construction feasibility evaluation rank shown using the evaluation rank for the period during which the road asset or the occupied property is constructible. For example, in Figure 4, the evaluation rank is shown as evaluation A if the asset being evaluated is in a "sound" state where no repair work is required, evaluation B if it is in a "moderate" state where medium-scale repair work is required, and evaluation C if it is in a "deteriorated" state where large-scale repair work is required. Regarding the construction scale used when outputting the evaluation rank, the user may set it arbitrarily. For example, medium-scale construction work is defined as having a cost related to the work of 5 million yen or more and less than 100 million yen, and large-scale construction work is defined as having a cost related to the work of 100 million yen or more. Also, the definitions of the above-mentioned medium-scale and large-scale construction work are just examples and are not limited to this.

[0031] Figure 5 shows the data structure of the construction information data table 22a4 held in the asset database 22a. As shown in Figure 5, the repair plan creation device 2 stores, for each construction ID which is a running number, the construction name indicating the type of construction obtained from the management device 1, the target type indicating whether it refers to a road asset or an occupied property, the target ID specifying which asset ID or property ID of the road asset and the occupied property to refer to, the construction method including information on the necessity of road excavation, the number of days required for the construction, the labor cost indicating the cost required for the construction, and the lane restriction range shown using latitude and longitude information for the restriction range during construction. For example, the construction method is the NATM method or the shield method, etc.

[0032] Also, regarding the various data in FIGS. 2 to 5, it is not limited to only being acquired from the management device 1, and it may be acquired from the outside.

[0033] <Hardware Configuration of Repair Plan Creation Device 2> FIG. 6 shows an example of the hardware configuration of the repair plan creation device 2. As shown in FIG. 6, the repair plan creation device 2 includes a processor 100a, a memory 101a, and an interface circuit 102a. The processor 100a, the memory 101a, and the interface circuit 102a are communicably connected to each other by a system bus 103a. The communication unit 20 in FIG. 1 is configured to be connectable to the interface circuit 102a and can receive information from the management device 1. In the configuration example of FIG. 6, the processing unit 21 is realized by the processor 100a, and the storage unit 22 is realized by the memory 101a. The processor 101a calls the repair plan creation program stored in the memory 101a to control the operation of the repair plan creation device 2 and execute arithmetic processing and the like. Also, the content of the storage unit 22 may be stored in the same memory 101a or in another memory.

[0034] Note that the processor 100a of the processing unit 21 is an example of a processing circuit, and examples include a CPU (Central Processing Unit), a DSP (Digital Signal Processer), and a system LSI (Large Scale Integration). The memory 101a of the storage unit 22 includes non-volatile or volatile semiconductor memories such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, and an EPROM (Enable Program Read Only Memory), a magnetic disk, a flexible memory, an optical disk, a compact disk, and a DVD (Digital Versatile Disc). Also, although the hardware configuration has been described for Embodiment 1, other embodiments can also adopt the same hardware configuration.

[0035] <Repair Plan Creation Process of Repair Plan Creation Device 2> The creation process of the repair plan in the repair plan creation device 2 will be described with reference to FIG. 7.

[0036] FIG. 7 shows a flowchart of the repair plan creation process performed by the repair plan creation device 2 of the repair plan support system. In step S101, the repair plan creation device 2 acquires information on road assets and occupied properties input from the user of the management device 1. Subsequently, in step S102, the repair plan creation device 2 registers the asset information acquired from the management device 1 in the asset database. In step S103, the repair plan creation device 2 refers to the asset information registered in the asset database and extracts a construction area overlap area where the positions of the road assets and occupied properties overlap. Subsequently, in step S104, the repair plan creation device 2 further extracts the constructible times of the road assets and occupied properties belonging to the extracted construction area overlap area. Thereafter, in step S105, the repair plan creation device 2 determines the feasibility of simultaneous construction based on the constructible times of the extracted road assets and occupied properties.

[0037] Here, the feasibility determination process of simultaneous construction performed by the repair plan creation device 2 will be described with reference to FIG. 8. FIG. 8 shows a flowchart of the feasibility determination process of simultaneous construction performed by the simultaneous construction feasibility determination unit in step S105 of FIG. 7. In step S101a, the repair plan creation device 2 determines whether road excavation is required for the construction of the occupied property extracted in step S104. If road excavation is required in step S101a, the repair plan creation device 2 determines that simultaneous construction is possible and, in S102a, proposes a time when the constructible times of each asset belonging to the construction area overlap area overlap. At this time, there may be multiple assets or a single asset.

[0038] Return to step S101a and explain the flow when road excavation is not required for the occupancy work. When it is not necessary to excavate the road for the occupancy work in step S101a, the repair plan creation device 2 determines in step S103a whether the construction area of the occupancy work is one lane on one side. When the construction area of the occupancy work is one lane on one side, the repair plan creation device 2 determines in step S104a whether the occupancy work can be carried out with the road excavated. When the repair plan creation device 2 determines that the occupancy work can be carried out with the road excavated, it determines that simultaneous work is possible and proceeds to step S102a to extract the period when the workable periods of each asset overlap. Also, when the repair plan creation device 2 determines in step S104a that the occupancy work cannot be carried out with the road excavated, it determines that simultaneous work is impossible and proposes the workable periods of each asset in ascending order of the workable periods of each asset belonging to the construction area overlap area so that the construction periods do not overlap.

[0039] Return to step S103a and explain the flow when the construction area of the occupancy work is not one lane on one side. When the construction area of the occupancy work is not one lane on one side in step S103a, the repair plan creation device 2 determines in step S106a whether all lanes of the road in the construction area are restricted. When not all lanes of the road in the construction area are restricted, the repair plan creation device 2 determines that simultaneous work is possible and proceeds to step S102a to propose the period when the workable periods of each asset belonging to the construction area overlap area overlap. Also, when the repair plan creation device 2 determines in step S106a that all lanes of the road in the construction area are restricted, it determines that simultaneous work is impossible and proposes the workable periods of each asset in ascending order of the workable periods of each asset belonging to the construction area overlap area so that the construction periods do not overlap.

[0040] Here, the feasibility of simultaneous construction determined by the repair planning device 2 in S106a will be described. For example, assume that there are lane 1 with asset 1, lane 2 with asset 2, and lane 3 with asset 3 on a three-lane road on one side. At this time, if the construction times of asset 1 and asset 2 are earlier than the constructible time of asset 3, the roads in lane 1 and lane 2 are restricted, it is determined that asset 1 and asset 2 can be under simultaneous construction, and one lane can be secured as a passable road in lane 3. However, if assets 1 to 3 on the road are determined to be in the constructible time, all lanes will be restricted due to lane restrictions associated with the construction, and there will be no passable lanes on the road. Therefore, if not all lanes of the road in the construction area are restricted in step S106a, the repair planning device 2 determines that simultaneous construction is possible because at least one passable lane can be secured. Also, if the repair planning device 2 determines in step S106a that all lanes of the road in the construction area are restricted, it determines that simultaneous construction is not possible because no passable lane can be secured.

[0041] Returning to FIG. 7, the processing after the repair planning device 2 determines the feasibility of simultaneous construction in step S105 will be described. In step S106, the repair planning device 2 calculates the construction times of each asset belonging to the construction area overlap area based on the determination result of the feasibility of simultaneous construction in step S105.

[0042] Here, the construction time calculated by the repair plan creation device 2 in step S106 will be described with reference to FIGS. 9 and 10. FIG. 9 shows an example of a repair plan created when the repair plan creation device 2 determines that each asset belonging to the construction area overlapping area is constructible during the same period. In FIG. 9, a construction time graph X created based on the deterioration prediction information of each asset belonging to the construction area overlapping area is shown. The deterioration prediction information refers to the deterioration prediction information data table 22a3, and in the constructibility evaluation rank, the evaluation A period is "sound", the evaluation B period is "moderate", and the evaluation C period is "deteriorated", which is shown in the construction time graph 3. In the construction time graph X of the present embodiment, the period after the evaluation B period is set as the target period of the constructible time, and the period within the frame is shown as the constructible period during the same period. The setting of the constructible time and the constructible period during the same period is not limited to this and can be arbitrarily changed by the user. For example, in the construction time graph X of FIG. 9, in the construction involving excavation of a road, it is recommended that the construction of the water pipe and gas pipe near the road be carried out simultaneously.

[0043] FIG. 10 shows an example of a repair plan created when the repair plan creation device 2 determines that each asset belonging to the construction area overlapping area is not constructible during the same period. For example, in FIG. 10, in the construction without road excavation, since the construction area is one lane on one side and the construction of the water pipe in the road excavation state is impossible, it is recommended that the construction be carried out in the order of water pipe construction and road construction.

[0044] Subsequently, in step S107, the repair plan creation device 2 outputs the created repair plan to the display device 14, and the repair plan is displayed on the display device 14. The output destination of the created repair plan is not limited to the display device 14, and it may be output to other systems and devices connected to the management device 1.

[0045] <Display screen on the display device 14> The display screen displayed on the display device 14 connected to the management device 1 will be described with reference to FIGS. 11 and 12.

[0046] FIG. 11 shows a schematic diagram of the main screen 4 displayed on the display device 14 connected to the management device 1. The main screen 4 includes a main information display area 41 for displaying information regarding assets or map information managed by the repair plan support system 100, and a function selection display area 42 for selecting the content to be displayed in the main information display area 41.

[0047] In FIG. 11, map information 43 is displayed in the main information display area 41, and information on the positions and the number of assets managed by the repair plan support system 100 is displayed as asset icons 44 on the map. The map information 43 can be freely moved and scaled by operating the input device 15. The user can easily grasp the positions and the number of assets by arbitrarily operating the input device 15 and visually recognizing the asset icons 44 on the map.

[0048] FIG. 12 shows a schematic diagram of the detailed screen 5 displayed on the display device 14 connected to the management device 1. The detailed screen 5 is displayed by pressing the asset icon 44 shown in FIG. 11 by operating the input device 15. The detailed screen 5 includes a repair plan display area 51 for displaying the repair plan of the asset corresponding to the selected asset icon 44, a construction area display area 52 for displaying the construction area of the asset, and a cancel button 53 for canceling the display of the detailed screen 5.

[0049] In the repair plan display area 51, repair plan information 51a created by the repair plan creation device 2 is displayed. The repair plan information 51a displayed in the repair plan display area 51 shows the recommended construction times of the respective assets corresponding to the selected asset icon 44, and the user can formulate a repair plan with reference to the displayed recommended construction times. The construction area display area 52 shows the restricted range due to the construction of the respective assets corresponding to the selected asset icon 44. Also, the entire area of the combined restricted ranges due to the construction of the respective assets becomes the construction area overlapping area. Therefore, for example, when there is no overlap in the restricted range of water pipe construction but there is a gas pipe construction that overlaps with the restricted range of road construction, the area combining the restricted ranges of road construction, water pipe construction, and gas pipe construction becomes the construction area overlapping area.

[0050] Here, in the construction area display region 52, it is desirable to show the regulation ranges of the respective assets in different display modes. Although the display mode of each asset is not particularly limited, for example, road system assets can be shown in blue and occupied properties can be shown in red, so that the user can visually recognize the type of asset. The way of showing these display modes may also be reflected in the repair plan display region 51. Further, in the present embodiment, the detailed screen 5 is arranged and displayed in the main information display region 41, but it may be displayed on the entire screen or may appear in a separate window.

[0051] According to the present embodiment, the repair plan creation device 2 can create an appropriate repair plan for the assets belonging to the construction area overlap region by considering in advance the construction positions and construction times of the road system assets and the occupied properties. Further, the repair plan created by the repair plan creation device 2 is transmitted to the management device 1 of the office of the road manager or public utility company who is the user, and is displayed on the display device 14 connected to the management device 1. The user can formulate an efficient and economical repair plan that prevents uneconomical situations associated with construction such as unexpected construction overlaps with reference to the repair plan displayed on the display device 14.

[0052] Embodiment 2. <Configuration of the repair plan support system 100> The configuration of the repair plan support system 100 in Embodiment 2 will be described with reference to FIG. 13. FIG. 13 shows a schematic diagram of the repair plan support system 100. In FIG. 13, the components denoted by the same reference numerals as in FIG. 1 indicate the same or corresponding components as those in Embodiment 1. Here, in contrast to the communication in the network 3 in Embodiment 1 being between the management device 1 and the repair plan creation device 2, in Embodiment 2, the management device 1 and the repair plan creation device 2 are also communicably connected to an external server 6.

[0053] The external server 6 is a system used when, for example, road administrators or public utility operators obtain information for maintaining and managing a plurality of assets. The system may be, for example, the Japan Road Traffic Information Center (JARTIC), the Road Management System (ROADIS), or the Road Information Provision System, but is not limited thereto. For example, the external server 6 may be a website under the jurisdiction of the organizer of an event that occupies a road such as a relay race or a festival.

[0054] The repair plan creation device 2 of Embodiment 2 acquires road regulation information 61 from the external server 6 via the network 3. The road regulation information 61 is, for example, other construction information not registered in the management device 1 or event information such as an event that occupies a road such as a relay race or a festival. The repair plan creation device 2 creates a repair plan considering the road regulation information 61 in the processing unit 21.

[0055] <Repair Plan Creation Process of Repair Plan Creation Device 2> The creation process of the repair plan in the repair plan creation device 2 will be described with reference to FIG. 14.

[0056] FIG. 14 shows a flowchart of the repair plan creation process performed by the repair plan creation device 2. In FIG. 14, steps SN (N is a natural number) equivalent to those in Embodiment 1 are given the same reference numerals, and the description will be made for the characteristic parts in Embodiment 2, and the description for equivalent steps will be omitted. In step S201, the repair plan creation device 2 acquires road regulation information 61 from the external server 6. The road regulation information 61 may be only the information of the area involved in the construction area overlap area extracted in step S103, or all the information that can be acquired from the external server 6 may be acquired in advance.

[0057] Next, in step S202, the repair plan creation device 2 calculates a construction time that avoids the period during which the road is restricted, based on the determination result of the feasibility of simultaneous construction of the road assets and occupied properties determined in step S105 and the road restriction information 61 acquired in S201. At this time, the construction time considering the road restriction information 61 created by the repair plan creation device 2 may be in the forms shown in FIGS. 9 and 10 shown in step S106 of the first embodiment, or other road restriction information 61 may be grasped as long as it can be grasped. Also, in FIG. 14, the timing at which the repair plan creation device 2 acquires the road restriction information 61 from the external server 6 is arbitrary, but the road restriction information 61 considered in step S202 is information related to the construction area overlap area extracted in step S103.

[0058] <Display screen on the display device 14> The display screen displayed on the display device 14 connected to the management device 1 will be described with reference to FIG. 15.

[0059] FIG. 15 shows a schematic diagram of the detailed screen 7 displayed on the display device 14 connected to the management device 1. From the main screen 4 to the detailed screen 7, it is transitioned by pressing the asset icon 44 on the main screen 4 by operating the input device 15. The detailed screen 7 includes a repair plan display area 51 that displays the repair plan of the asset corresponding to the selected asset icon 44, a construction area display area 52 that displays the construction area of the asset, and a road restriction information display area 71 that displays the road restriction information regarding the construction area of the asset.

[0060] In the repair plan display area 51, repair plan information 51b created in consideration of road regulation information 61 is displayed. In the repair plan information 51b displayed in the repair plan display area 51, for each asset corresponding to the selected asset icon 44, the recommended construction time considering the road regulation information 61 in the area where the asset is located is shown. Thus, the user can formulate a repair plan considering the road regulation information at the location where the asset is located, referring to the displayed recommended construction time. The construction area display area 52 is the same as in the first embodiment. Also, the road regulation information display area 71 visually displays the range of road regulation related to the asset when the asset icon 44 is selected. Thereby, the range where road regulation is performed can be visually grasped.

[0061] Also, as an example, in the detailed screen 7 in FIG. 15, the repair plan display area 51, the construction area display area 52, and the road regulation information display area 71 are each displayed as tabs. Each of the tabbed display areas can be displayed or erased by operating the operation button 72 with the input device 15. Also, similar to the first embodiment, the display mode of the detailed screen 7 is not limited to this, and for example, it may be displayed across the entire screen or appear in a separate window.

[0062] According to the present embodiment, the repair plan creation device 2 creates a repair plan based on information on both road assets and occupied properties in consideration of the road regulation information 61 acquired from the external server 6, and transmits the repair plan to the management device 1. The user can formulate a repair plan for road assets and occupied properties considering the road regulation information by checking the created repair plan on the display device 14 connected to the management device 1.

[0063] Embodiment 3. <Repair Plan Creation Process of Repair Plan Creation Device 2> The repair plan creation process of the repair plan creation device 2 in Embodiment 3 will be described with reference to FIG. 16. In FIG. 16, the same step numbers SN (N is a natural number) as those in Embodiment 1 are used, and some parts are omitted for the convenience of explanation. Hereinafter, the description will be made on the characteristic parts in Embodiment 3. In step S301, the repair plan creation device 2 newly registers an asset based on the information of the asset input from the user of the management device 1. Subsequently, in step S302, the repair plan creation device 2 extracts the construction area overlapping areas of the road assets and the occupied properties by referring to the asset newly registered in step S301 and the information in the asset database 22a.

[0064] <Display screen on the display device 14> The display screen displayed on the display device 14 connected to the management device 1 will be described with reference to FIG. 17.

[0065] FIG. 17 shows a schematic diagram of the detailed screen 5 displayed on the display device 14 connected to the management device 1. In FIG. 17, the detailed screen 5 is provided with a new registration button 8 for implementing the new registration of an asset. The new registration of the asset executed by the repair plan creation device 2 in step S301 can be started by pressing the new registration button 8 through the operation of the input device 15. In FIG. 17, the new registration button 8 is superimposed on the construction area display area 52, but it is not limited thereto and may be provided at any position on the screen. Also, when a location where the asset icon 44 displayed on the display device 14 is not located is selected so that the user can newly register an asset at an arbitrary location, the same function as the new registration button 8 may be executed.

[0066] Fig. 18 shows a schematic diagram of the new asset registration on the detailed screen 5 displayed on the display device 14 connected to the management device 1. In Fig. 18, the detailed screen 5 is provided with an asset information input area 81 for inputting information on the asset to be newly registered. From the construction area display area 52 shown in Fig. 17 to the asset information input area 81, it transitions by pressing the new registration button 8 through the operation of the input device 15 by the user. Subsequently, in the asset information input area 81 of Fig. 18, as information on the asset to be newly registered, input is performed on whether the asset is a road asset or an occupied property, information such as the name or type of the asset, the deterioration prediction information of the asset, and the construction information of the asset including the construction method, the necessity of excavation related to the construction, the number of construction days, the construction cost, the presence or absence of lane regulation, and the lane regulation range. The information on the asset to be newly registered described above is not limited to this, and items of information related to the asset may be added or deleted.

[0067] When a new asset is registered by the user, the repair plan creation device 2 creates a repair plan with reference to the information on the newly registered asset and the information in the asset database 22a. The repair plan created by the repair plan creation device 2 is displayed as repair plan information 51 in the repair plan display area 51 of the detailed screen 5 displayed on the display device 14.

[0068] According to the present embodiment, by creating a repair plan with reference to the information on the asset newly registered by the repair plan creation device 2 and the information on the assets in the asset database 22a, a repair plan considering assets not stored in the asset database 22a can be displayed on the display device 14 connected to the management device 1 of the office. Thereby, the road administrator or the public utility provider can formulate an economic repair plan including assets not stored in the asset database 22a by checking the repair plan displayed on the display device 14.

[0069] Embodiment 4. <Configuration of the repair plan support system 100> The configuration of the repair plan support system 100 in Embodiment 4 will be described with reference to FIG. 19. FIG. 19 shows a schematic diagram of the repair plan support system 100. In FIG. 19, the components denoted by the same reference numerals as those in FIG. 2 indicate the same or corresponding components as those in Embodiment 2. Here, although the road regulation information 61 was acquired from the external server 6 in Embodiment 2, in this embodiment, the construction period information 9 is acquired.

[0070] The external server 6 is, for example, a system for managing information on construction work for a road administrator or a public utility company to maintain and manage a plurality of assets. The system may be provided inside or outside the user's office. Also, in this embodiment, although the external server 6 is described as the acquisition source of the construction period information 9, it is also possible to adopt a configuration in which the management device 1 can calculate the construction period information 9.

[0071] The repair plan creation device 2 of Embodiment 4 acquires the construction period information 9 from the external server 6. The construction period information 9 is, for example, information obtained by calculating the period from the application for construction work to its permission or the period from the application for construction work to its completion. The repair plan creation device 2 creates a repair plan considering the construction period information 9 in the processing unit 21.

[0072] <Repair plan creation process of the repair plan creation device 2> The process of creating a repair plan in the repair plan creation device 2 will be described with reference to FIG. 20.

[0073] Fig. 20 shows a flowchart of the repair plan creation process performed by the repair plan creation device 2. In Fig. 20, the same step numbers SN (N is a natural number) as in the first embodiment are used, and for the sake of explanation, some parts are omitted. Hereinafter, the characteristic parts in the fourth embodiment will be described. The repair plan creation device 2 acquires the construction period information 9 from the external server 6 in step S401. The construction period information 9 is information on the area related to the construction area overlapping area extracted in step S103. The construction period information 9 is not limited to only the information on the area related to the construction area overlapping area, and all construction information that can be obtained from the external server 6 may be acquired in advance.

[0074] Subsequently, in step S402, the repair plan creation device 2 calculates the construction time based on the result of the feasibility of simultaneous construction of the road system assets and the occupied properties determined in step S105 and the construction period information 9 acquired in S401. At this time, the construction time considering the construction period information 9 created by the repair plan creation device 2 may be in the form shown in Figs. 9 and 10 in step S106 of the first embodiment, or any other form as long as the construction period information 9 can be grasped. Also, in Fig. 20, the timing at which the repair plan creation device 2 acquires the construction period information 9 from the external server 6 is arbitrary, but the construction period information 9 considered in step S402 is information related to the construction area overlapping area extracted in step S103.

[0075] <Display screen on the display device 14> The display screen displayed on the display device 14 connected to the management device 1 will be described with reference to Fig. 21. Fig. 21 shows a schematic diagram of the detailed screen 5 displayed on the display device 14 connected to the management device 1. In Fig. 21, the same reference numerals as in the first embodiment are used, and for the sake of explanation, some parts are omitted. Hereinafter, the characteristic parts in the fourth embodiment will be described.

[0076] In the repair plan display area 51, repair plan information 91 created in consideration of the construction time information 9 is displayed. In the repair plan information 91 displayed in the repair plan display area 51, for each asset corresponding to the selected asset icon 44, the recommended construction time in which the construction period information 9 of the area where the asset is located is reflected in the repair plan as the period information 92 is shown. In FIG. 21, as the period information 92, the construction application period indicating the period from the application for construction to the permission and the construction period indicating the period from the start of construction to the completion are shown. Thereby, the user can formulate a repair plan considering from the application for construction to the completion of the road construction at the location where the asset is located with reference to the displayed recommended construction time. Also, the settings regarding the time of the construction application period or the construction period can be arbitrarily changed by the user. For example, the construction application period may be the period from the application for construction to the start of construction, or the construction period may be the period from the permission for construction to the completion of construction.

[0077] According to the present embodiment, the repair plan creation device 2 can create a repair plan considering both the information of road assets and occupied properties after considering the construction time information 9 acquired from the external server 6, and transmit the repair plan to the management device 1. The user can formulate a repair plan for road assets and occupied properties considering the period from the application for construction to the permission by checking the created repair plan on the display device 14 connected to the management device 1.

[0078] Note that, as the repair plan support system 100 shown in each embodiment, the management device 1, the repair plan creation device 2, and the external server 6 are provided and described, but it is not limited thereto. For example, the management device 1 may be provided with the functions of the repair plan creation device 2 and the external server 6. Also, the repair plan support system 100 may include all of the configurations of the management device 1, the repair plan creation device 2, and the external server 6, or may omit some or all of them.

[0079] Embodiment 5. <Configuration of the repair plan support system 100> The configuration of the repair plan support system 100 in the embodiment will be described with reference to FIG. 21. FIG. 21 shows a schematic diagram of the repair plan support system 100. In FIG. 21, the components with the same reference numerals as those in FIGS. 1, 13, and 19 represent the same or corresponding components as those in Embodiment 2. Here, the repair plan device 2 in Embodiment 5 has a prediction unit A1 as a function of the processing unit 21 and a prediction database B2 in the storage unit 22.

[0080] The prediction unit A1 predicts the recommended construction time of the assets managed by the user and creates construction recommended time data for each construction area where the assets are located. The created construction recommended time data is stored in the prediction database B.

[0081] As an example, the prediction unit A1 creates construction recommended time data by predicting the future recommended construction time of assets using Artificial Intelligence (AI). The prediction unit A1 may predict the future recommended construction time using the data stored in the asset database 22a. The prediction of the recommended construction time may be, for example, when a new asset is registered in Embodiment 3, in view of the deterioration of the registered asset, predicting the time of each possible construction evaluation rank of the asset, or predicting the construction time based on external information obtained from the external server 6 described in other embodiments. When the processing unit 21 posts the recommended construction time predicted by the prediction unit A1 to the user, for example, the assets for which construction is recommended may be displayed on the display device 14 as a list, or the assets for which construction is recommended may be superimposed on the map information 43. The recommended construction time to be posted may be any other method that is easy for the user to recognize, such as notifying by email. Machine learning or deep learning is used as an algorithm for predicting the recommended construction time, but it is not limited thereto. The recommended construction time predicted by the prediction unit A1 is provided to the user via the communication unit 20 by the processing of the processing unit 21 and is also provided to the storage unit 22. The recommended construction time provided to the storage unit 22 is stored in the prediction database B as a construction recommended time data table B1, which is, for example, a data table.

[0082] A learned model for predicting the recommended timing of future construction may be generated by learning the construction information of the asset, the predicted deterioration information of the asset, and the information about the events that affect the asset. In this case, the prediction unit A1 predicts the recommended timing of future construction using the predicted deterioration information of the asset, the information about the events that affect the construction of the asset, and the learned model. The events that affect the construction of the asset are, for example, other construction information, event information such as a relay race or a festival that occupies a road, and road regulation information 61. The prediction unit A1 can predict the recommended timing of future construction with higher accuracy because the information about the events that affect the construction of the asset is included in the learning.

[0083] According to the present embodiment, the repair plan creation device 2 can create a repair plan that predicts the recommended timing of future construction of the asset and transmit the repair plan to the management device 1. The user can implement more efficient and economical asset construction by formulating a repair plan in consideration of the predicted recommended construction timing.

[0084] Although the present disclosure has described the repair work of the asset, it can also be applied to other types of work. For example, for all types of work such as new construction or improvement construction, it is only necessary that the structure to be constructed is clear.

[0085] The repair plan support system 100 shown in each embodiment is merely an example, and appropriately combining, modifying, or omitting each embodiment is also included in the scope of the technical idea shown in the embodiment.
