Description

  Embodiments described herein relate generally to a road maintenance management system, a control method, and a computer program.

  Conventionally, on main trunk roads such as expressways and directly-controlled national roads, road pavements are inspected by road surface property measuring vehicles. Based on the results of the inspection, the road manager regularly determines the roads to be repaired, drafts a repair plan, and executes the repairs, and performs road maintenance management systematically. In order to support such road maintenance management, a technique for selecting a road to be repaired and determining the priority of repair based on inspection data acquired by road inspection has been proposed.

  However, many of the conventional techniques are often premised on that sufficient information regarding road conditions is acquired by road inspection. For this reason, the conventional technology may not always be suitable for road maintenance and management in local governments where sufficient inspection cannot be performed due to factors such as lack of budget and personnel.

(First embodiment)
FIG. 1 is a schematic diagram illustrating an overview of a road maintenance system 100 according to the first embodiment.
The road maintenance management system 100 is a system that supports a road manager's maintenance work by calculating the priority of road repair (hereinafter referred to as “repair priority”). In addition, the road here is a public road managed by a public institution such as a national or local public entity. The road maintenance management system 100 calculates a repair priority based on attribute information, inspection information, and input information. The attribute information is information indicating road attributes such as width, extension, position, pavement time, road usage, and road usage frequency. Such attribute information is known information, and can be acquired from, for example, an existing external system that holds the attribute information.

  The inspection information (state information) is information indicating the pavement state of the road. The inspection information is generated from various inspection data acquired in road inspection. For example, when the inspection data is acquired as image data obtained by imaging a road, inspection information such as a pavement crack rate, rutting condition, and flatness is acquired by performing image processing on the image data. This inspection data is acquired by periodic road inspections and daily inspections by road managers. Regular road inspections and daily inspections by road managers are conducted mainly by public organizations such as national and local governments.

  The periodic inspection is a large-scale inspection that is regularly and systematically performed using a dedicated vehicle such as a road surface property measuring vehicle. In general, regular inspections are performed once every two to three years on major arterial roads such as expressways and directly-controlled national roads. In such a periodic inspection, inspection data is acquired for a certain range of roads. On the other hand, daily inspections by road managers are mainly local inspections for problems and important points. For this reason, in daily inspections by road managers, inspection data is acquired for roads within a limited range. Hereinafter, inspection data acquired by periodic inspection is referred to as periodic inspection data, and inspection data acquired by daily inspection is referred to as individual inspection data.

The input information is various information related to roads transmitted on a daily basis. For example, the input information may be information transmitted via an SNS (Social Networking Service) such as LINE (registered trademark), Facebook (registered trademark), Twitter (registered trademark), or may be transmitted to a dedicated WEB site. It may be information to be posted. The input information may be voice data in which a telephone such as a complaint or a request sent to the window is recorded, or mail data transmitted to the mail address of the window. As described above, the input information may be any information that does not depend on the acquisition unit, the transmission unit, and the use as long as it is information about the road. The road maintenance system 100 collects input information transmitted in various manners as described above, performs processing such as data extraction and format conversion, and can handle the collected input information in its own system. Convert to and accumulate. Many techniques for extracting necessary data and converting formats from various types of data have been proposed, and the road maintenance system 100 is configured to collect input information using such existing techniques. May be.

  Conventionally, road repair priorities have been determined based on attribute information and periodic inspection information, but in order to carry out large-scale inspections such as periodic inspections regularly and systematically, there are many Cost. Therefore, when regular inspection cannot be performed, sufficient periodic inspection information required for determination of repair priority cannot be acquired, and repair priority may not be determined. For such problems, the road maintenance management system 100 according to the embodiment can compensate for the lack of periodic inspection information using the individual inspection information and input information, so that sufficient periodic inspection information cannot be acquired. The repair priority can be determined.

  Hereinafter, the configuration of the road maintenance management system 100 according to the embodiment will be described in detail. However, in order to simplify the description of the embodiment, in the following description, the road maintenance management system 100 is a dedicated WEB that accepts posts regarding roads.

At this time, the information input to the position input area 205 is converted into position information represented by latitude and longitude and transmitted.

Returning to the description of FIG.
The importance calculation unit 107 calculates the importance (first importance information) for each piece of input information acquired by the input information acquisition unit 106. For example, the importance calculation unit 107 scores each input information based on one or more predetermined scoring criteria. Then, the importance level calculation unit 107 calculates the total score in all scoring standards as the importance level of the input information.

FIG. 6 is a diagram showing a specific example of scoring criteria for input information.
In the example of FIG. 6, “the number of cases in the vicinity”, “evaluation”, “type of poster”, “keyword”, and “posting time” are shown as examples of scoring criteria. “Number of cases in the vicinity” is a criterion for determining whether or not many other posts are generated near the position where certain input information is posted. The “number of cases in the vicinity” can be determined from the position information included in the input information. If the number of “neighborhoods” is large, it is determined that many problems have occurred in the area, and thus a high score is given.

  “Evaluation” is a criterion for judging how much evaluation is given to certain input information. “Evaluation” can be determined from the evaluation information included in the input information. If the “evaluation” is high, it is judged that there are many people who have similar opinions, so a high score is given.

  “Contributor type” is a criterion for determining how much influence the contributor of the input information is. The “type of poster” can be determined from the poster attribute information in the input information record. When the “type of poster” is, for example, a member of the Diet, a landowner, or a government official, the opinion is judged to reflect the opinions of many local residents, and thus a high score is given.

  The “keyword” is a standard for determining how much danger the input information is complaining about. The “keyword” can be determined from the text information of the input information record. For example, when the text information includes words indicating specific damage such as “injury” or “accident”, a high score is given to the input information. Also, if the text information contains only road conditions such as “holes” and “steps”, it is judged that no specific damage has occurred, so a low score is given to the input information. The

  “Posting time” is a standard for judging how fresh the input information has. The “posting time” can be determined from the input date of the input information record. When the input date is new, it is determined that the input information has high freshness and is highly likely to accurately represent the actual state, and thus a high score is given to the input information.

  The importance calculation unit 107 scores each input information according to the scoring criteria as described above, and calculates the importance of each input information. The importance calculation unit 107 registers the calculated importance value in the importance information of the corresponding input information record.

  Note that the above-described scoring criteria and scoring concept are examples in the present embodiment. The scoring standard for calculating the importance and the concept of scoring may be formulated based on a standard or concept different from the above as long as it is possible to more appropriately judge the opinions of the contributors.

Returning to the description of FIG.
The administrator registration unit 108 registers the road administrator's evaluation for the input information in the input information table 1041. Specifically, the road administrator operates the input unit 102 to input an administrator evaluation for the input information. The administrator registration unit 108 acquires information input from the input unit 102 by the road administrator. The information acquired here includes the identification information of the input information and the evaluation value of the road manager. The administrator registration unit 108 registers the acquired evaluation value in the administrator evaluation information of the input information record indicated by the identification information of the input information.

  The inspection data acquisition unit 109 acquires inspection information input by the operation of the road administrator from the input unit 102. The inspection data that is input includes a road ID. The inspection data acquisition unit 109 generates inspection information indicating the state of the road surface based on the acquired inspection data. The inspection data acquisition unit 109 registers the generated inspection information in the inspection information of the road information record indicated by the road ID.

  The priority calculation part 110 calculates the repair priority of each road based on input information and road information. The priority calculation unit 110 registers the calculated repair priority in the road information table 1051. The priority calculation unit 110 calculates a repair priority in accordance with a road manager instruction output from the input unit 102.

  The display control unit 111 generates screen data for displaying a priority display screen indicating the repair priority. The display control unit 111 outputs the generated screen data to the display unit 103.

FIG. 7 is a diagram illustrating a specific example of the priority display screen.
The priority display screen 300 is an example of a priority display screen indicating repair priority. The priority display screen 300 is a screen that displays a list of repair priorities for each road. In the case of the example in FIG. 7, the priority display screen 300 includes road identification information and repair priority information, road type, pavement year, inspection information, safety, use frequency, use area, traffic volume, and importance. It is configured as a screen to be displayed. The priority display screen 300 may be configured to display information other than that displayed in the example of FIG. 7 if road identification information and repair priority information are included. Thus, by displaying a list of repair priorities for each road and information used to calculate the repair priorities, the road administrator can easily confirm the appropriateness of the calculated repair priorities. Is possible.

FIG. 8 is a flowchart showing the flow of priority calculation processing performed by the road maintenance management system 100.
First, the input information acquisition unit 106 determines whether input information has been received (step S101). When the input information is received (step S101—YES), the input information acquisition unit 106 registers the received input information in the input information table 1041 (step S102). When the input information is registered, the input information acquisition unit 106 instructs the importance calculation unit 107 to calculate the importance of the registered input information.

  The importance calculation unit 107 refers to the input information table 1041 and calculates the importance for each input information based on the value of each item included in the input information record (step S103). The importance calculation unit 107 registers the calculated importance of each input information in the importance information of the corresponding input information record.

  On the other hand, when input information is not received in step S101 (step S101-NO), the road maintenance management system 100 does not execute step S102 and step S103, but proceeds to step S104.

  Next, the inspection data acquisition unit 109 determines whether inspection data has been input (step S104). When the inspection data is input (step S104—YES), the inspection data acquisition unit 109 generates inspection information based on the input inspection data (step S105). The inspection data acquisition unit 109 registers the generated inspection information in the road information storage unit 1051 (step S106).

  On the other hand, when inspection data is not input in step S104 (step S104-NO), the road maintenance management system 100 does not execute step S105 and step S106, but proceeds to step S107.

  Next, the priority calculation unit 110 determines whether or not a priority calculation instruction has been input (step S107). When the priority calculation instruction has not been input (step S107—NO), the process returns to step S101, and the road maintenance management system 100 repeats the collection of input information and inspection data. On the other hand, when a priority calculation instruction is input (step S107—YES), the priority calculation unit 110 calculates a repair priority for each road based on the inspection information, input information, and attribute information (step S107). S108).

For example, as illustrated in the example of FIG. 7, the priority calculation unit 110 calculates the repair priority based on the inspection information, safety, usage frequency, use area, traffic volume, and importance value. The safety is a value indicating the level of safety required for the corresponding road. The usage frequency is a value indicating the level of usage frequency determined from a facility or the like existing in the vicinity of the corresponding road. The use area is a value indicating the level of importance set according to the use of the area near the corresponding road. The traffic volume is a value indicating the level of importance set according to the traffic volume of the corresponding road. The values of safety, usage frequency, use area, and traffic volume are registered in advance as road attribute information in the road information record. The priority calculation unit 110 acquires importance information on each road from the input information table 1041. In addition, the priority calculation unit 110 acquires inspection information and road attribute information for each road from the road information table 1041. The priority calculation unit 110 calculates the repair priority by the following formula, for example, based on the acquired inspection information, road attribute information, and importance information.
Repair priority = inspection information x (safety + usage frequency + restricted area + traffic volume) + importance

  The priority calculation unit 110 registers the calculated repair priority of each road in the priority information of the corresponding road information record. Then, the priority calculation unit 110 instructs the display control unit 111 to display the priority display screen.

  The display control unit 111 generates screen data for displaying the priority display screen on the display unit 103. The display control unit 111 outputs the generated screen data to the display unit 103. The display unit 103 acquires screen data from the display control unit 111 and displays a priority display screen (step S109).

  The road maintenance management system 100 according to the first embodiment configured as described above gives priority to repairing a road to be managed based on input information transmitted from a poster and inspection information acquired by road inspection. Determine the degree. As described above, the road maintenance management system 100 uses the input information transmitted from the contributor for the determination of the repair priority, and even if it is difficult to obtain the inspection information by the periodic inspection, the road repair priority is given. The degree can be determined.

  Further, the road maintenance management system 100 according to the embodiment calculates the importance of the input information for each input information. By calculating the importance, the road maintenance management system 100 can weight the input information, and can determine a more appropriate repair priority.

  Next, a modified example of the road maintenance management system 100 of the first embodiment will be described.

  The priority display screen may display a cost required for repairing each road. For example, in this case, the road maintenance management system 100 stores in advance information on the cost of repair work required per unit area. The display control unit 111 refers to the road information table 1051 and acquires road attribute information of each road. The display control unit 111 calculates the cost required for repairing each road based on the width and extension information of each road included in the acquired road attribute information and the cost information per unit area. The display control unit 111 includes the necessary information necessary for repairing each road in the screen data and outputs the screen data to the display unit 103.

  The repair priority may be calculated based on any other information that affects the priority of repair work in addition to the inspection information, road attribute information, and importance information. For example, manager evaluation information may be used for calculating the repair priority.

  The scoring standard for the importance calculating unit 107 to calculate the importance and the way of giving the score may be configured to be changeable as necessary. In this case, for example, a storage unit that stores information (standard information) indicating the scoring standard illustrated in FIG. 6 as a scoring standard table is provided, and the importance calculation unit 107 calculates the importance by referring to the scoring standard table. To do. In this case, the administrator registration unit 108 (reference information acquisition unit) may be configured to update the scoring reference table according to the input of the road administrator from the input unit 102.

(Second Embodiment)
FIG. 9 is a functional block diagram showing a functional configuration of the road maintenance management system 100a of the second embodiment.
In FIG. 9, functional units having the same functions as those in FIG.

Different from the road maintenance system 100 of the first embodiment.

  The map information storage unit 112 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. Map information including roads to be managed is stored in advance in the map information storage unit 112.

  The priority calculation unit 110a performs the same processing as the priority calculation unit 110 and calculates the repair priority. Furthermore, the priority calculation unit 110 a instructs the display control unit 111 a on the mode of the priority display screen to be displayed on the display unit 103 according to the operation of the road administrator input from the input unit 102. There are a first mode and a second mode as modes of the priority display screen. The first mode of the priority display screen is a screen that displays a list of repair priorities for each road as shown in the example of FIG. On the other hand, the 2nd aspect of a priority display screen is a screen which maps and displays repair priority on a map like the example of FIG. 10 mentioned later. The instruction from the road manager includes screen selection information indicating that the priority display screen is displayed in either the first mode or the second mode.

  The display control unit 111a generates screen data that causes the display unit 103 to display the priority display screen in either the first mode or the second mode in response to an instruction from the priority calculation unit 110a. The display control unit 111 a outputs the generated screen data to the display unit 103.

FIG. 10 is a diagram illustrating a specific example of the second mode of the priority display screen.
The priority display screen 400 is an example of a second mode of the priority display screen. The priority display screen 400 is a screen in which the repair priority for each road is mapped to a map. For example, in the example of FIG. 10, the repair priority for each road is represented by the type of line superimposed on the road on the map. In the example of FIG. 10, the repair priority is classified and displayed in four stages of high, medium, low, and fine. A line indicated by reference numeral 401 indicates that the repair priority is high. A line indicated by reference numeral 402 indicates that the repair priority is medium. A line indicated by reference numeral 403 indicates that the repair priority is low. A line indicated by reference numeral 404 indicates that the repair priority is fine. Further, the input information mapped to the map indicates a place where each input information is posted.

  When the mode of the priority display screen indicated by the instruction of the priority calculation unit 110a indicates the second mode, the display control unit 111a is illustrated in the example of FIG. 10 based on the map information, input information, and road information. Screen data for displaying the priority display screen of the second mode is generated.

  The road maintenance management system 100a according to the second embodiment configured as described above can display the repair priority of each road in the form of a map. Thus, the repair priority of each road is displayed in the form of a map, so that the road manager can easily grasp the repair priority of each road for each region. The road administrator repairs both the global viewpoint and the local viewpoint by using the priority display screen of the first mode and the priority display screen of the second mode according to the situation. It becomes possible to grasp the priority, and it is possible to make a repair plan more appropriately.

  Next, a modified example of the road maintenance management system 100a of the second embodiment will be described.

  The priority display screen of the second aspect is not limited to the input information and priority information, and any other information may be displayed. Further, the manner in which the priority information is displayed is not limited to the manner represented by lines as in the example of FIG. For example, when the inspection data is acquired only on a part of the road, the priority information may be displayed as a point on the map. Also in this case, as in FIG. 10, each point is displayed in such a manner that the degree of priority indicated by the priority information can be visually identified.

The road maintenance management system 100b is different from the road maintenance management system 100a of the second embodiment in that it further includes a construction information storage unit 113, a construction information acquisition unit 114, and an effect determination unit 115.

  The construction information storage unit 113 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The map information storage unit 112 stores a construction information table 1131 that holds construction information. The construction information is information regarding the road on which the repair work has been performed.

FIG. 12 is a diagram showing a specific example of the construction information table 1131.
The construction information table 1131 has a construction information record for each road ID. The construction information record has values of road ID, construction date, construction content, and effect information. The road ID is identification information of a road on which repair work is performed. The road ID corresponds to the road ID in the road information table 1051. The construction execution time represents the time when the road repair work indicated by the road ID was performed. The construction content is information indicating the content of the repair work performed. The effect information is information indicating the effect of the repair work performed. The construction information record is generated by the construction information acquisition unit 114 based on the construction information and registered in the construction information table 1131.

Returning to the description of FIG.
The construction information acquisition unit 114 acquires construction information input by the operation of the road administrator from the input unit 102. The input construction information includes road identification information. The construction information acquisition unit 114 generates a construction information record based on the acquired construction information. The construction information acquisition unit 114 registers the generated construction information record in the construction information table 1131. Of the items included in the construction information record, the value of effect information is registered by the effect determination unit 115.

  The effect determination unit 115 determines the effect of the repair work performed based on the input information and the work information. Specifically, the effect determination unit 115 determines the effect of the repair work performed by comparing the contents of the input information posted before and after the repair work. For example, the effect determination unit 115 scores the input information posted at the time of repair work based on one or more predetermined scoring standards. And the effect determination part 115 calculates the sum total of the score in all the scoring standards before and after repair work. The effect determination unit 115 determines the effect of the repair work performed based on the total score.

  As a method of scoring input information by the effect determination unit 115, the same method as the scoring method in the calculation of importance shown in FIG. 7 can be used. For example, among the scoring standards shown in the example of FIG. 7, when “the number of nearby cases” is used as the scoring standard for determining the effect, it is determined that the situation in the area has been improved if the number of cases has decreased after the construction. The input information may be given a high score.

  The road maintenance and management system 100b of the third embodiment configured as described above determines the effect of the repair work by acquiring the work information and comparing the input information registered before and after the repair work. Can do. By judging this effect, the road manager can more appropriately make a future construction plan based on the effect of the repair work performed.

  In addition, the road maintenance management system 100b of 3rd Embodiment may be comprised so that the effect of the repair work determined by the effect determination part 115 may be displayed on the display part 103. FIG. In that case, the effect determination unit 115 outputs effect information indicating the determined effect of the repair work to the display control unit 111a. The display control unit 111a generates screen data for displaying an effect display screen indicating effect information. The display control unit 111 a causes the display unit 103 to display the effect display screen by outputting the generated screen data to the display unit 103. The information displayed on the effect display screen may be information other than the effect information. For example, images acquired as input information before and after construction may be displayed, or images acquired as inspection data before and after construction may be displayed.

  According to at least one embodiment described above, the road maintenance system according to the embodiment is different from attribute information indicating road attributes, inspection information acquired by road inspection, and a main body that performs road inspection. By having a repair priority determination unit that determines the priority of road repair based on the input information acquired by the subject, the priority of road repair can be determined more easily.

  2, 9, and 11 may be mounted on a single device or may be distributed and mounted on a plurality of devices. In any case, the system including the apparatus configured as described above can function as the road maintenance management systems 100, 100a, and 100b.

  The functions of the road maintenance management systems 100, 100a, and 100b may be implemented as a cloud system. In this case, the road maintenance management systems 100, 100a and 100b calculate the repair priority in response to the request from the administrator terminal device used by the road administrator, and include the calculation result in the screen data of the priority display screen. It may be configured as a system provided to the administrator terminal device.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
