Summary of the Invention

Problems to be Solved by the Invention

[0005] The following analysis is provided by the inventor of the present invention. The above-described road inspections are usually carried out for each management entity (road manager) such as a country, a prefecture, a municipality, or a special company. However, the inspection route along which the vehicle travels does not always match the route of the road to be inspected. In addition, when the length of the road is long, due to budget constraints, it is required to plan the repair of the road by dividing it into multiple sections, and from this perspective, road inspections are often carried out in multiple stages. Therefore, for example, even when inspections are carried out using the road maintenance support system of Patent Document 1, multiple inspection routes are created and inspections are carried out step by step.

[0006] Inspection routes created from such a perspective may include road sections other than the roads managed by the management entity that is the inspection implementation entity. In that case, since inspections are not carried out in that road section, a kind of loss occurs. Further, even if inspections were carried out in that road section, there is a problem that the measured inspection data cannot be utilized because the road performance evaluation items and the road diagnosis criteria based on those values differ for each management entity.

[0007] An object of the present invention is to provide a road inspection system, a road inspection method, and a program recording medium that can contribute to the efficiency improvement of inspections (diagnoses) of a plurality of roads with different management entities (road managers).

Means for Solving the Problems

[0008] According to a first perspective, there is provided a road inspection system including means for creating a road inspection route including a first road managed by a first road manager and a second road managed by a second road manager different from the first road manager, means for receiving inspection data obtained by measuring predetermined items along the road inspection route from a vehicle that has traveled along the road inspection route, means for diagnosing the first inspection data measured on the first road included in the inspection data using the first diagnosis criteria of the first road manager, and means for diagnosing the second inspection data measured on the second road included in the inspection data using the second diagnosis criteria of the second road manager.

[0009] According to a second aspect, a computer comprising means for storing road data including a first road managed by a first road administrator and a second road managed by a second road administrator different from the first road administrator creates a road inspection route including the first road managed by the first road administrator and the second road managed by a second road administrator different from the first road administrator, receives inspection data obtained by measuring predetermined items along the road inspection route from a vehicle that has traveled the road inspection route, diagnoses the first inspection data measured on the first road included in the inspection data using a first diagnostic criterion of the first road administrator, and diagnoses the second inspection data measured on the second road included in the inspection data using a second diagnostic criterion of the second road administrator. A road inspection method is provided. This method is associated with a specific machine, namely a computer comprising means for storing the above-described road data.

[0010] According to a third aspect, a computer program (hereinafter, “program”) for realizing the functions of the above-described road inspection system is provided. This program is input into a computer device via an input device or externally via a communication interface, stored in a storage device, and causes a processor to be driven according to predetermined steps or processes. Further, this program can display its processing results, including intermediate states if necessary, step by step via a display device, or can communicate with an external device via a communication interface. A computer device for that purpose typically includes, as an example, a processor, a storage device, an input device, a communication interface, and, if necessary, a display device that can be connected to each other by a bus. Further, this program can be recorded on a computer-readable (non-transitory) storage medium.

Advantages of the Invention

[0011] According to the present invention, it becomes possible to efficiently inspect (diagnose) a plurality of roads with different management entities (road administrators).

Embodiments for Carrying Out the Invention

[0013] First, an overview of an embodiment of the present invention will be described with reference to the drawings. Note that the reference numerals attached to the drawings in this overview are for convenience of each element as an example to assist understanding, and are not intended to limit the present invention to the illustrated embodiments. Also, the connection lines between blocks such as the drawings referred to in the following description include both bidirectional and unidirectional ones. The one-way arrow schematically shows the flow of the main signal (data) and does not exclude bidirectionality. The program is executed via a computer device, and the computer device includes, for example, a processor, a storage device, an input device, a communication interface, and a display device as necessary. Further, this computer device is configured to be communicable with devices inside or outside the device (including computers) via the communication interface, regardless of wired or wireless. Also, ports or interfaces are provided at the input / output connection points of each block in the figure, but the illustration thereof is omitted.

[0014] In one embodiment of the present invention, as shown in FIG. 1, it can be realized by a road inspection system 10 including a road inspection route creation unit 12, an inspection data reception unit 13, and a diagnosis unit 14.

[0015] The road inspection route creation unit 12 functions as means for creating a road inspection route including a first road managed by a first road administrator and a second road managed by a second road administrator different from the first road administrator. In the example of FIG. 1, the road inspection route creation unit 12 reads data from a road information database (road information DB) 11 including a road ledger, a pavement ledger, etc., and creates a road inspection route.

[0016] The inspection data reception unit 13 functions as means for receiving inspection data obtained by measuring predetermined items along the road inspection route from a vehicle that has traveled along the road inspection route. Note that the setting of the road inspection route for the vehicle can be in a form of reading a recording medium storing road inspection route information into the in-vehicle terminal of the vehicle, or in a form of transmitting the road inspection route information to the vehicle using communication means. Of course, a form in which a passenger of the vehicle manually inputs the road inspection route into the in-vehicle terminal may also be adopted.

[0017] The diagnosis unit 14 functions as means for diagnosing the first inspection data measured on the first road included in the inspection data by using the first diagnosis criteria of the first road administrator stored in the road administrator-specific diagnosis criteria storage unit 15. Further, the diagnosis unit 14 also functions as means for diagnosing the second inspection data measured on the second road included in the inspection data by using the second diagnosis criteria of the second road administrator stored in the road administrator-specific diagnosis criteria storage unit 15. The diagnosis unit 14 outputs the result of the diagnosis as a road inspection route diagnosis result. In the example of FIG. 1, one diagnosis unit 14 is configured to diagnose using the first and second diagnosis criteria, but a configuration in which a plurality of diagnosis units are provided for each diagnosis criteria is also applicable.

[0018] Also, in the example of FIG. 1, the road information database (road information DB) 11 and the road administrator-specific diagnosis criteria storage unit 15 are assumed to be provided in a device different from the road inspection system 10, but information corresponding to the road information DB 11 and the road administrator-specific diagnosis criteria storage unit 15 may be held in the storage device of the road inspection system 10 (see FIG. 2).

[0019] According to the road inspection system 10 described above, it is possible for a road administrator to create a road inspection route including a plurality of different roads and have the vehicle perform an inspection. And according to the road inspection system 10, it is possible to perform a diagnosis based on the inspection data received from the vehicle using the diagnosis criteria set by each road administrator and obtain a diagnosis result of the road inspection route.

[0020] [First Embodiment] Next, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a diagram showing the configuration of a road inspection system according to the first embodiment of the present invention. Referring to FIG. 2, a road inspection system 100 capable of receiving inspection data from a road inspection vehicle equipped with a road inspection device is shown. As the road inspection vehicle equipped with a road inspection device, for example, a vehicle equipped with an inspection device capable of measuring the crack ratio of the road surface, the rutting amount of the road surface, and the International Roughness Index (IRI) can be used. Of course, a dedicated road surface property measurement vehicle capable of performing these measurements may be used, or a vehicle equipped with an in-vehicle device having a camera and an accelerometer such as a general drive recorder may also be used.

[0021] Referring to FIG. 2, the road inspection system 100 includes a road information DB 101, a road inspection route creation unit 102, an inspection data reception unit 103, a diagnosis unit 104, a diagnosis criterion storage unit 105 for each road administrator, and a diagnosis result reflection unit 106.

[0022] The road information DB 101 is a database that stores various types of information for creating a road inspection route. The road information DB 101 may be a Geographic Information System (GIS) with an additional function of managing a road map plan view, documents, and a pavement register. Also, as the road information DB 101, it may be possible to use data of information of a road management system (ROADIS) of the General Incorporated Association Road Management Center or other road management systems used by various local governments.

[0023] The road inspection route creation unit 102 creates a road inspection route for the roads located in the inspection target area selected by the user. At this time, the user can select an area where the inspection time has arrived by referring to the inspection implementation status of each route in the road information DB 101. If this area includes a first road managed by a first road administrator and a second road managed by a second road administrator different from the first road administrator, the road inspection route creation unit 102 creates a road inspection route including these first and second roads. Of course, the road inspection system 100 may have a function of correcting the created road inspection route through interactive processing with the user. For example, the road inspection route creation unit 102 may create a route that preferentially inspects roads that have not been inspected for a predetermined period, or a route that preferentially inspects locations where there have been complaints from residents. Also, the road inspection route creation unit 102 may create a route that preferentially inspects roads that need to be frequently inspected by referring to past diagnosis results.

[0024] The road inspection route created by the road inspection route creation unit 102 is set in the road inspection vehicle (hereinafter, "vehicle") in various ways. For example, the same route as the road inspection route created by the road inspection route creation unit 102 may be input into the vehicle's car navigation system or road inspection device to set the route. Also, when the road inspection route creation unit 102 has a function of outputting road inspection route information to an arbitrary recording medium, the route may be set in the vehicle's car navigation system or road inspection device via the recording medium.

[0025] The inspection data receiving unit 103 receives inspection data measured along the road inspection route from the vehicle that has traveled on the road inspection route. In the following description, the inspection data receiving unit 103 will be described as receiving inspection data including the crack ratio of the road surface, the amount of rutting on the road surface, and the International Roughness Index (IRI). Also, according to the road diagnosis criteria, items other than the following, for example, composite indices such as MCI (Maintenance Control Index: pavement maintenance management index), may be added to the measurement items. Further, when the road diagnosis criteria use another index such as flatness (standard deviation of vertical unevenness) instead of the International Roughness Index (IRI), it may be converted from the International Roughness Index (IRI).

[0026] FIG. 3 is a diagram showing an example of inspection data received by the road inspection system 100 of the present embodiment from a vehicle. In the example of FIG. 3, in addition to the route name, jurisdiction (road administrator), and inspection date and time, the crack ratio, rutting amount, and measurement results of IRI for each section of the route, and inspection data including road surface images are shown. When the road inspection route includes routes (roads) with different jurisdictions (road administrators), the road inspection system 100 receives inspection data of different routes (roads) in chronological order of measurement. In the present embodiment, it is assumed that the vehicle calculates and transmits the crack ratio, (maximum) rutting amount, and IRI in each section, but the vehicle may transmit data necessary for calculating each item to the road inspection system 100, and the road inspection system 100 may calculate each item.

[0027] Note that the crack ratio can be calculated by (crack area (m 2 )) / (survey target area (m 2 )) × 100. Specifically, the survey target section can be divided into predetermined meshes (for example, 0.5 m square), and the mesh method of area conversion can be used, where if there is only one crack in one section, it is 60%, and if there are two or more cracks, it is 100%. The crack ratio is not limited to the above calculation method and can be calculated using a method set by a local government or the like.

[0028] The road administrator-specific diagnosis criterion storage unit 105 stores the diagnosis criteria for roads set for each jurisdiction (road administrator). FIG. 4 is an example of the diagnosis criteria (performance evaluation criteria) for each jurisdiction (road administrator) stored in the road administrator-specific diagnosis criterion storage unit 105. For example, the diagnosis criteria (performance evaluation criteria) in the upper part of FIG. 4 indicate the diagnosis criteria (performance evaluation criteria) of Road Administrator A. For the roads of Road Administrator A, it is required to diagnose the road based on whether the content of the inspection data falls into any category (classification). Similarly, the diagnosis criteria (performance evaluation criteria) in the lower part of FIG. 4 indicate the diagnosis criteria (performance evaluation criteria) of Road Administrator B. As shown in FIG. 4, the diagnosis criteria (performance evaluation criteria) may vary depending on the jurisdiction (road administrator).

[0029] The diagnosis criteria for roads are generally set based on the required service level and the assumed magnitude of damage progression (degree of progression). For example, in Japan, the diagnosis criteria are different for national roads, prefectural roads, municipal roads, expressways, and private roads. Also, even between prefectures and between municipalities, the diagnosis criteria may differ due to the effects of climate, salt damage, etc. In addition, for expressways, etc., there may be cases where diagnosis criteria are set according to unique criteria from the perspective of safety.

[0030] Also, the same jurisdiction (road administrator) may set a classification of roads (road classification) based on the magnitude of damage progression (degree of progression), etc. In this case, even for the same road administrator, different diagnosis criteria (performance evaluation criteria) may be set depending on the road classification. The road administrator-specific diagnosis criterion storage unit 105 stores the diagnosis criteria (performance evaluation criteria) that can be different for each road administrator in this way. In the following description, "minor repair required" in FIG. 4 means a state where minor repairs are necessary to maintain the function of the road, and "major repair required" means a state where the damage level of the road is large and comprehensive renovation is necessary.

[0031] The diagnosis unit 104 diagnoses the road using the diagnosis criteria (performance evaluation criteria) corresponding to the inspection data among the diagnosis criteria (performance evaluation criteria) shown in FIG. 4 for the inspection data received by the inspection data receiving unit 103. Hereinafter, in the present embodiment, when at least one item of the inspection data falls within Category III shown in the diagnosis criteria (performance evaluation criteria) shown in FIG. 4, the diagnosis unit 104 diagnoses the section as "requiring repair". Further, when at least one item of the inspection data falls within Category II shown in the diagnosis criteria (performance evaluation criteria) shown in FIG. 4, the diagnosis unit 104 diagnoses the section as "requiring minor repair". If the diagnosis method itself also differs for each jurisdiction (road administrator), the diagnosis method for each jurisdiction (road administrator) may be used. For example, there may be a case where a certain road administrator decides to diagnose a section as "requiring repair" when at least two items of the inspection data fall within Category III shown in the diagnosis criteria (performance evaluation criteria) shown in FIG. 4. In this case, the diagnosis criteria for each road administrator may be stored in the road administrator-specific diagnosis criteria storage unit 105, and the diagnosis unit 104 may be similarly diagnosed.

[0032] As described above, the diagnosis unit 104 sequentially diagnoses the inspection data received by the inspection data receiving unit 103 and outputs the result as the road inspection route diagnosis result. Further, the diagnosis unit 104 outputs the road inspection route diagnosis result to the diagnosis result reflection unit 106.

[0033] The diagnosis result reflection unit 106 updates the inspection implementation status of the corresponding route in the road information DB 101 using the road inspection route diagnosis result output from the diagnosis unit 104.

[0034] Subsequently, the operation of the present embodiment will be described in detail with reference to the drawings. FIG. 5 is a flowchart showing the operation of the road inspection system 100 according to the first embodiment of the present invention. Referring to FIG. 5, first, the road inspection system 100 creates a road inspection route (step S001).

[0035] Next, the road inspection system 100 receives inspection data from the vehicle (step S002). Next, the road inspection system 100 reads out the diagnostic criteria of the road administrators of the roads included in the road inspection route from the road administrator-specific diagnostic criteria storage unit 105 (step S003). Here, when the road inspection route includes roads of a plurality of road administrators, the road inspection system 100 reads out the diagnostic criteria of each road administrator.

[0036] Next, the road inspection system 100 analyzes (diagnoses the road) the inspection data using the read diagnostic criteria of the road administrator (step S004). Next, the road inspection system 100 updates the inspection implementation status of the corresponding route in the road information DB 101 using the road inspection route diagnostic result output from the diagnosis unit 104 (step S005).

[0037] FIG. 6 is a diagram showing the diagnostic result of a road by the road inspection system 100 according to the first embodiment of the present invention. In the example of FIG. 6, an example is shown in which the national highway AAA, the prefectural road BBB, and the national highway CCC are included in the road inspection route. In the example of FIG. 6, it is determined that the section from 300 m to 400 m of the national highway AAA requires repair, and the section from 400 m to 500 m requires renovation. Also, it is determined that the section from 200 m to 300 m of the national highway CCC requires repair. Here, although the prefectural road BBB is determined to be all sound, this is diagnosed according to the diagnostic criteria (performance evaluation criteria) set by the prefecture, which is the road administrator of the prefectural road BBB. For this reason, the crack ratio, rutting amount, and IRI of the inspection data of the prefectural road BBB may not be determined to be sound according to the diagnostic criteria (performance evaluation criteria) set by the country, which is the road administrator of the national highway AAA and the national highway CCC.

[0038] Thus, according to the present embodiment, it is possible to select an arbitrary area, create a road inspection route, and complete the inspection and diagnosis of the roads on the route in one drive. The reason is that it is allowed that the road inspection route includes roads with different road administrators, and the road inspection system 100 adopts a configuration in which the diagnostic criteria corresponding to the road administrator of the road where the inspection data is measured are selected and diagnosed.

[0039] Note that the output mode of the road diagnosis result by the road inspection system 100 is not limited to the form shown in FIG. 6. For example, as shown in FIG. 7, the road inspection system 100 may have a function of creating an inspection execution status map in which a layer indicating the road inspection route and the inspection execution result is superimposed and displayed on the GIS map stored in the road information DB 101. In the example of FIG. 7, the section determined to be sound is represented by a symbol with the symbol "I" inside a circle, and the sections determined to require repair and require renovation are represented by symbols with the symbols "II" and "III" in white inside a black circle. According to the inspection execution status map as shown in FIG. 7, it becomes possible to visually grasp the inspection execution status and the locations requiring repair and renovation in terms of areas. As a result, it becomes possible to convert the inspection execution status that was individually managed by means of a paving ledger or the like for each road administrator into a comprehensive management. And by providing the diagnosis result or the inspection execution status map to each road administrator, it becomes easier to formulate a road maintenance and repair plan for each road administrator. Furthermore, when there is a repair contractor or the like that performs road maintenance under a commission from a plurality of road administrators, by providing the diagnosis result or the inspection execution status map to the repair contractor, it becomes easier to formulate a comprehensive road maintenance and repair plan.

[0040] [Second Embodiment] Subsequently, a second embodiment in which a road inspection route distribution function is added to the road inspection system will be described in detail with reference to the drawings. FIG. 8 is a diagram showing the configuration of the road inspection system 100a according to the second embodiment of the present invention. The difference in configuration from the first embodiment shown in FIG. 2 is that a road inspection route distribution unit 107 is added to the road inspection system 100a. Since the other configurations are the same as those in the first embodiment, the following description will focus on the differences.

[0041] The road inspection route distribution unit 107 distributes the road inspection route information created by the road inspection route creation unit 102 to the vehicle equipped with the inspection device via a wireless network, the Internet, or the like. Note that, as shown in FIG. 8, the vehicle that is the distribution destination of the road inspection route information does not have to be one vehicle.

[0042] The vehicle that has acquired the road inspection route information travels along the road inspection route to conduct inspections and transmits inspection data to the road inspection system 100a. Note that the vehicle that has acquired the road inspection route information does not necessarily travel along the same route as the road inspection route and does not necessarily need to conduct inspections on the roads along the road inspection route. It only needs to transmit inspection data that includes sections overlapping with the road inspection route.

[0043] FIG. 9 is a flowchart showing the operation of the road inspection system according to the second embodiment of the present invention. The difference from the operation of the road inspection system 100 according to the first embodiment shown in FIG. 5 is that after the road inspection route is created by the road inspection system 100a, the road inspection route is distributed by the road inspection route distribution unit 107 (step S101).

[0044] The subsequent operations are the same as those in the first embodiment. When the road inspection system 100a receives inspection data from a vehicle (step S002), it reads out the diagnosis criteria of the road administrator of the road included in the road inspection route from the road administrator-specific diagnosis criteria storage unit 105 (step S003).

[0045] Next, the road inspection system 100a analyzes the inspection data (diagnosis of the road) using the read diagnosis criteria of the road administrator (step S004). Finally, the road inspection system 100a updates the inspection implementation status of the corresponding route in the road information DB101 using the road inspection route diagnosis result output from the diagnosis unit 104 (step S005).

[0046] As described above, according to the present embodiment, the setting of the road inspection route for conducting road inspections is automated. As a result, it is also possible to receive inspection data including sections overlapping with the road inspection route from a large number of vehicles. By receiving multiple inspection data for the same section and conducting diagnoses, it is possible to expect an improvement in the accuracy of the diagnosis results.

[0047] As described above, each embodiment of the present invention has been explained. However, the present invention is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments can be made without departing from the basic technical idea of the present invention. For example, the system configuration shown in each drawing, the configuration of each element, and the data representation form are examples for assisting the understanding of the present invention, and are not limited to the configurations shown in these drawings.

[0048] For example, in the above-described first embodiment, an example in which the combination of different road administrators is a country and a prefecture has been described. However, the combination of different road administrators is not limited to this. For example, the present invention can be similarly applied when the first road administrator is a prefecture and the second road administrator is a municipality. Of course, in an area where different roads of three or more road administrators are mixed, when diagnosing the roads of these three or more road administrators, the present invention can be similarly applied.

[0049] In addition, when the vehicle performing the above-described road inspection finds a local pothole or the like during the inspection, it may be provided with a function of reporting to the road inspection systems 100 and 100a. The road inspection systems 100 and 100a may be provided with a function of instructing road managers or the like to perform repairs or repairs as necessary.

[0050] In addition, the procedures shown in the above-described first to second embodiments can be realized by a program that causes a computer (9000 in FIG. 10) that functions as the road inspection systems 100 and 100a to realize the functions of the road inspection system. Such a computer is exemplified by a configuration including a CPU (Central Processing Unit) 9010, a communication interface 9020, a memory 9030, and an auxiliary storage device 9040 in FIG. 10. That is, the CPU 9010 in FIG. 10 may execute a road inspection route creation program or a data diagnosis program, and perform an update process of each calculation parameter held in the auxiliary storage device 9040 or the like.

[0051] That is, each part (processing means, function) of the road inspection systems 100 and 100a shown in the above-described embodiments can be realized by a computer program that causes a processor mounted on these devices to execute the above-described respective processes using its hardware.

[0052] Finally, the preferred forms of the present invention will be summarized. [First Form] (Refer to the road inspection system according to the first perspective above) [Second Form] For the first and second diagnostic criteria used by the above-described road inspection system, different diagnostic criteria are provided for each road classification according to the progress degree of road damage. The road inspection system can adopt a configuration in which, among the diagnostic criteria determined by the first and second road administrators, the first and second inspection data are diagnosed using the diagnostic criteria corresponding to the road classification in which the inspection data was measured. [Third Form] The above-described road inspection system further includes: means for creating an inspection implementation status map that displays the road inspection route on a map on which the first road and the second road are displayed; means for superimposing and displaying, on the first road and the second road of the inspection implementation status map, the result of analyzing the first inspection data using the first diagnostic criterion and the result of analyzing the second inspection data using the second diagnostic criterion. [Fourth Form] The above-described road inspection system can adopt a configuration including means for distributing the road inspection route to a vehicle equipped with an inspection device capable of creating the inspection data. [Fifth Form] (Refer to the road inspection method according to the second perspective above) [Sixth Form] (Refer to the program according to the third perspective above) Note that the above fifth to sixth forms can be developed into the second to fourth forms in the same manner as the first form. ​
