Description

Technical Field

[0001] The invention relates to the technical field of highway maintenance, and in particular to a method for rapid inspection and maintenance of highways. Background Art

[0002] The rapid economic development of modern society has led to a continuous increase in traffic volume on highways. A large number of vehicles have caused serious wear and damage to the road surface, such as cracks, potholes, rutting and other road surface diseases. At the same time, high traffic volume also increases the risk of damage to traffic facilities, which need to be maintained and updated in time to ensure driving safety. Therefore, a method for rapid inspection and maintenance of highways is needed.

[0003] Prior art, such as an invention patent application with announcement number CN115762181A, discloses an information-based method and device for highway maintenance and road construction safety management, which relates to the field of highway maintenance technology. The method comprises the following steps: obtaining basic pavement information and greening maintenance information of the road, analyzing and calculating the basic pavement information and greening maintenance information to obtain a maintenance value, wherein the maintenance value is a numerical value obtained by digitally processing the basic pavement information and greening maintenance information and associating and calculating the value used to indicate that the road needs maintenance; comparing the maintenance value with a preset maintenance threshold to obtain a maintenance warning set, which has the effect of being able to take corresponding warning signals to vehicles on the road according to different maintenance conditions of the road surface, thereby ensuring driving safety and shortening the time required for the vehicle to reach the destination; furthermore, being able to arrange the nearest workers to carry out timely road maintenance according to different maintenance conditions of the road surface.

[0004] The above scheme has the following technical problems: 1. The existing technology does not have a multi-dimensional maintenance characteristic value analysis. The existing technology may simply focus on individual problems such as road surface diseases or damage to traffic facilities, while ignoring other aspects such as greening maintenance. For example, poor growth of green vegetation may affect the ecological environment and driving vision of the highway, but in the absence of a systematic evaluation, it may not be taken seriously, resulting in a decline in the overall service quality of the highway, and it is difficult to accurately judge the maintenance needs and urgency of each section. This may lead to an unreasonable allocation of maintenance resources, such as wasting resources on sections with low maintenance needs, while sections that really need emergency maintenance are not handled in a timely manner.

[0005] 2. In the prior art, there is a lack of effective information sharing platform between departments such as road administration, traffic police, and maintenance construction units. For example, after inspectors discover road surface diseases, they may need to inform the maintenance construction unit through cumbersome telephone or document delivery. In this process, information may be delayed, lost or misunderstood, resulting in the inability to carry out maintenance work in a timely manner. There is no clear departmental collaborative task allocation process. When facing maintenance work, each department may not know their responsibilities and work order. For example, when it is necessary to urgently close a road section for maintenance, the traffic police department and the road administration department may cause work delays due to unclear responsibilities, or there may be duplication of work or poor connection in traffic diversion and on-site investigation. For different stages of maintenance work, such as preliminary preparation, construction process and finishing work, there is a lack of a unified coordination mechanism, resulting in ineffective coordination between departments. For example, at the end of the maintenance work, if the traffic restoration work of the traffic police department and the quality inspection work of the road administration department are not reasonably arranged, the road closure time may be extended, affecting the normal operation of traffic.

[0006] 3. Existing technologies may lack real-time monitoring means for maintenance progress, and cannot accurately grasp the progress of each road section during the maintenance process. For example, the progress can only be understood through regular reports from maintenance construction units, but such reports may be untimely or inaccurate, making it difficult to detect delays or other problems in time. The allocation of departmental tasks at the final stage is unreasonable, and there may be insufficient traffic diversion personnel in the traffic police department, leading to traffic congestion; or too many inspection personnel in the road administration department, resulting in waste of resources. Failure to accurately allocate personnel based on the actual number of vehicles waiting to pass and maintenance inspection needs is not conducive to the smooth completion of maintenance work and the rapid recovery of traffic. Summary of the invention

[0007] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a method for rapid inspection and maintenance of expressways.

[0008] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a method for rapid inspection and maintenance of highways, including: Step 1, analysis of maintenance inspection characteristics: performing maintenance inspections on each section of the target highway through an unmanned aerial vehicle, thereby obtaining the maintenance inspection characteristics corresponding to each section, and then analyzing and obtaining the greening maintenance characteristic values, pavement maintenance characteristic values ​​and facility maintenance characteristic values ​​corresponding to each section.

[0009] Step 2: Assessment of maintenance urgency: Based on the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section, assess whether each road section needs maintenance. If each road section needs maintenance, analyze the maintenance urgency of each road section and allocate collaborative tasks among departments.

[0010] Step 3: Analysis of maintenance progress: When a road section is under maintenance, several collection time points are set to analyze the maintenance progress adaptation value corresponding to the road section at each collection time point, and then evaluate whether the maintenance progress corresponding to the road section at each collection time point is at the final maintenance progress.

[0011] Step 4: Allocation of collaborative tasks among departments: When the maintenance progress of the road section at a certain collection time point is at the final maintenance progress, the tasks of each department are then allocated.

[0012] Preferably, the analysis obtains the greening maintenance characteristic values, pavement maintenance characteristic values ​​and facility maintenance characteristic values ​​corresponding to each road section. The specific analysis process is as follows: A1. Obtain the greening maintenance inspection characteristics corresponding to each road section. The greening maintenance inspection characteristics include vegetation coverage rate, vegetation deviation value and night vegetation transmittance. The vegetation coverage rate, vegetation deviation value and night vegetation transmittance corresponding to each road section are input into the greening maintenance analysis model, and the greening maintenance value corresponding to each road section is output.

[0013] A2. Obtain the pavement maintenance inspection characteristics corresponding to each road section. The pavement maintenance inspection characteristics include the pavement disease area ratio, pavement flatness and pavement friction coefficient. The pavement disease area ratio, pavement flatness and pavement friction coefficient corresponding to each road section are input into the pavement maintenance analysis model, and the pavement maintenance characteristic value corresponding to each road section is output.

[0014] A3. Obtain the facility maintenance inspection characteristics corresponding to each road section. The facility maintenance inspection characteristics include the facility integrity rate, facility cleanliness and facility function normality rate. The facility integrity rate, facility cleanliness and facility function normality rate corresponding to each road section are input into the pavement maintenance analysis model, and the facility maintenance characteristic value corresponding to each road section is output.

[0015] Preferably, the evaluation of whether each road section needs maintenance is performed by the following specific analysis process: the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section are respectively compared with the set greening maintenance value threshold, pavement maintenance value threshold and facility maintenance value threshold; if the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to a certain road section are all greater than the set greening maintenance value threshold, pavement maintenance value threshold and facility maintenance value threshold, then it is evaluated that the road section does not need maintenance; if as long as one of the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to a certain road section is less than or equal to the set greening maintenance value threshold, pavement maintenance value threshold and facility maintenance value threshold, then it is evaluated that the road section needs maintenance.

[0016] Preferably, the analysis of the maintenance urgency corresponding to each road section has a specific evaluation process as follows: the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section are input into a road section maintainability evaluation model, and the road section maintainability result is output.

[0017] The road section maintenance results include values ​​of 1 and -1. When the road section maintenance result of a road section is 1, it indicates that the corresponding road section maintenance of the road section is high. Conversely, when the road section maintenance result of a road section is -1, it indicates that the corresponding road section maintenance of the road section is low.

[0018] Preferably, the expression of the road section maintainability assessment model is: , where represents the maintenance urgency result corresponding to the g-th road section, represents the maintenance urgency assessment value corresponding to the g-th road section, is the set maintenance urgency assessment value threshold, g represents the number corresponding to each road section, and g is a positive integer.

[0019] The greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section are recorded as , and , substitute into the calculation formula Among them, , , They are the standard greening maintenance value, standard road surface maintenance value, and standard facility maintenance value corresponding to the set road section. , , They are respectively the weight factor corresponding to the set road section greening maintenance value, the weight factor corresponding to the road surface maintenance value, and the weight factor corresponding to the facility maintenance value.

[0020] Preferably, the allocation of collaborative tasks among the various departments is specifically analyzed as follows: B1. If the corresponding road section of a certain road section has a high maintainability, the traffic police department is first notified to close the road section as soon as possible, and traffic guidance signs and signal lights are set up in advance to guide vehicles to divert in an orderly manner. After the closure of the road section is completed, the road administration department is notified to go to the road section. The road administration department evaluates the maintenance type, materials and personnel configuration of the road section, and compiles the evaluated maintenance type, materials and personnel configuration into a report and sends it to the maintenance department. The maintenance department allocates the number of suitable maintenance personnel corresponding to the current road section based on the maintenance type, materials and personnel configuration report evaluated by the road administration department, and goes to the road section for maintenance.

[0021] B2. If the corresponding road section of a certain road section has low maintainability, the traffic police department will be notified first to evaluate the traffic flow of the road section, and then the time period corresponding to the minimum traffic flow of the road section will be obtained. Subsequently, the traffic police department will use the time period corresponding to the minimum traffic flow of the road section as the maintenance period, and send the maintenance period to the road administration department. After the road administration department obtains the maintenance period, it will notify the road administration department personnel in advance to conduct an evaluation during the maintenance period. At the same time, the traffic police department will close the road section before the maintenance period arrives, and set up traffic guidance signs and signal lights in advance to guide vehicles to divert in an orderly manner. After the closure of the road section is completed, the road administration department will be notified to go to the road section. The road administration department will evaluate the maintenance type, materials and personnel configuration of the road section, and organize the evaluated maintenance type, materials and personnel configuration into a report and send it to the maintenance department. The maintenance department will allocate the number of suitable maintenance personnel corresponding to the current road section based on the maintenance type, materials and personnel configuration report evaluated by the road administration department, and go to the road section for maintenance.

[0022] Preferably, the maintenance progress adaptation value corresponding to the road section is analyzed at each collection time point, and the specific analysis process is as follows: first, the road administration department uploads the corresponding maintenance progress characteristics at each collection time point of the road section, and the maintenance progress characteristics include the maintenance task completion ratio, time progress deviation and remaining maintenance work time, and inputs the maintenance task completion ratio, time progress deviation and remaining maintenance work time corresponding to the road section at each collection time point into the maintenance progress analysis model, and outputs the maintenance progress adaptation value corresponding to the road section at each collection time point.

[0023] Preferably, the evaluation of whether the maintenance progress corresponding to the road section at each collection time point is at the final maintenance progress is performed by comparing the maintenance progress adaptation value corresponding to the road section at each collection time point with the standard final maintenance progress adaptation value set for the road section. If the maintenance progress adaptation value corresponding to the road section at a certain collection time point is the same as the standard final maintenance progress adaptation value set for the road section, it means that the maintenance progress corresponding to the road section at the collection time point is at the final maintenance progress.

[0024] Preferably, the standard end maintenance progress adaptation value set for the road section is specifically set as follows: C1, obtaining the greening maintenance characteristic value, pavement maintenance characteristic value and facility maintenance characteristic value corresponding to the maintenance of each reference road section in the historical period, and comparing the greening maintenance characteristic value, pavement maintenance characteristic value and facility maintenance characteristic value corresponding to the road section with the greening maintenance characteristic value, pavement maintenance characteristic value and facility maintenance characteristic value corresponding to the maintenance of each reference road section; if the greening maintenance characteristic value, pavement maintenance characteristic value and facility maintenance characteristic value corresponding to the road section are the same as the greening maintenance characteristic value, pavement maintenance characteristic value and facility maintenance characteristic value corresponding to the maintenance of a reference road section, then the reference road section is used as the reference road section corresponding to the road section; C2. Obtain the maintenance progress adaptation value corresponding to each maintenance progress corresponding to the reference road section, and then obtain the maintenance progress adaptation value corresponding to the maintenance progress at the end of the reference road section, and record the maintenance progress adaptation value corresponding to the maintenance progress at the end of the reference road section as the standard end maintenance progress adaptation value of the road section.

[0025] Preferably, the collaborative tasks of various departments are deployed, and the specific analysis process is as follows: D1. When the maintenance progress corresponding to the road section at a certain collection time point is at the final maintenance progress, the number of vehicles waiting to pass and the number of maintenance inspections corresponding to the road section at the collection time point are obtained, and the number of vehicles waiting to pass corresponding to the road section at the collection time point is compared with the number of vehicles waiting to pass corresponding to each number of evacuated personnel of the traffic police department. If the number of vehicles waiting to pass corresponding to the road section at the collection time point is the same as the number of vehicles waiting to pass corresponding to a certain number of evacuated personnel of the traffic police department, then the number of evacuated personnel of the traffic police department is recorded as the number of evacuated personnel of the traffic police department corresponding to the road section at the collection time point, and the number of evacuated personnel of the traffic police department corresponding to the road section at the collection time point is sent to the traffic police department, and the traffic police department deploys the corresponding number of evacuated personnel to the road section.

[0026] D2. Compare the number of maintenance inspections corresponding to the road section at the collection time point with the number of maintenance inspections corresponding to the number of inspectors of the road administration department. If the number of maintenance inspections corresponding to the road section at the collection time point is the same as the number of maintenance inspections corresponding to a certain number of inspectors of the road administration department, then record the number of inspectors of the road administration department as the number of inspectors of the road administration department corresponding to the road section at the collection time point, and send the number of inspectors of the road administration department corresponding to the road section at the collection time point to the road administration department, and the road administration department will deploy the corresponding number of inspectors to the road section.

[0027] The beneficial effects of the present invention are as follows: 1. The embodiments of the present invention can accurately evaluate the maintenance status of each section of the highway from multiple angles through a comprehensive analysis of the greening maintenance characteristic values, the road surface maintenance characteristic values, and the facility maintenance characteristic values. This multi-dimensional analysis method is more scientific and comprehensive than a single inspection indicator, and can more accurately reflect the actual situation of the section, providing a reliable basis for subsequent maintenance decisions. For sections with higher maintainability, maintenance resources are given priority, and for sections with lower maintainability, maintenance time can be reasonably arranged according to actual conditions, thereby improving the allocation efficiency of maintenance resources, ensuring that the sections that need maintenance the most can be processed in a timely manner, and ensuring the safety and smoothness of the highway.

[0028] 2. In the embodiment of the present invention, in the road sections with high maintenance, the traffic police department can close the road sections and set up traffic guidance signs in the first time, the road administration department can make timely assessments and send reports to the maintenance department, and the maintenance department can quickly deploy personnel for maintenance. This close departmental collaboration process ensures rapid response in emergency situations, reduces delays caused by poor communication between departments, and improves the overall efficiency of maintenance work. For road sections with low maintenance, the traffic police department determines the maintenance period based on traffic flow assessment, and the road administration department and the maintenance department prepare and carry out maintenance work at the appropriate time. This method can reasonably arrange maintenance tasks on the premise of ensuring the normal operation of traffic, avoid excessive impact on traffic, and make full use of resources, improve the planning and scientific nature of maintenance work, and the road administration department can accurately analyze the maintenance progress adaptation value at each collection time point by uploading the maintenance progress characteristics to the maintenance progress analysis model. This enables the management department to understand the progress of maintenance work in real time, identify problems in time and take measures to adjust them. When the maintenance progress is at the final stage, the traffic police department and the road administration department will be allocated the appropriate number of evacuation personnel and inspection personnel according to the number of vehicles waiting to pass and the number of maintenance inspections. It can ensure that after the maintenance work is completed, the traffic can be quickly and safely restored to normal. The traffic police department can effectively divert traffic and avoid traffic congestion; the road administration department can comprehensively check the maintenance quality to ensure the safe operation of the highway, which improves the efficiency and quality of the entire maintenance work.

[0029] 3. The embodiments of the present invention can timely discover problems in various sections of the expressway and carry out maintenance, effectively preventing the deterioration of road surface diseases, the destruction of the green environment and the damage of traffic facilities. For example, timely repair of road surface cracks can prevent the cracks from expanding and causing aggravated road surface damage, thereby extending the service life of the road surface; timely treatment of vegetation diseases and insect pests can maintain the beauty and ecological function of greening; timely maintenance of traffic facilities can ensure that drivers can clearly obtain traffic information and improve driving safety. During the maintenance process, reasonable traffic control and guidance measures are used to reduce the impact of maintenance work on traffic. Traffic guidance signs and signal lights are set in advance to guide vehicles to divert in an orderly manner, avoiding traffic congestion and accidents. At the same time, the maintenance period is reasonably arranged according to the traffic flow, which ensures the traffic capacity of the expressway, improves the efficiency and quality of traffic operations, and provides a safer and smoother travel environment for drivers and passengers.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0031] Figure 1 The present invention is a flowchart of the steps for implementing the method. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiments of the present invention Figure 1 As shown, a method for rapid inspection and maintenance of highways includes: step one, analysis of maintenance inspection characteristics: performing maintenance inspections on each section of the target highway by using drones to obtain maintenance inspection characteristics corresponding to each section, and then analyzing and obtaining greening maintenance characteristic values, pavement maintenance characteristic values ​​and facility maintenance characteristic values ​​corresponding to each section.

[0034] In a specific embodiment, the analysis obtains the greening maintenance characteristic values, pavement maintenance characteristic values ​​and facility maintenance characteristic values ​​corresponding to each road section. The specific analysis process is as follows: A1. Obtain the greening maintenance inspection characteristics corresponding to each road section. The greening maintenance inspection characteristics include vegetation coverage rate, vegetation deviation value and night vegetation transmittance. The vegetation coverage rate, vegetation deviation value and night vegetation transmittance corresponding to each road section are input into the greening maintenance analysis model, and the greening maintenance value corresponding to each road section is output.

[0035] It should be noted that the image analysis software taken by the drone can identify the green vegetation pixels and the total image pixels to obtain the vegetation coverage rate. The orthophotos taken by the drone can be used to measure the straightness of the edges of hedges and shrubs, or the similarity with the standard shape. The deviation value of its outline from the ideal shape can be analyzed by the image software to obtain the vegetation deviation value. The light transmittance of vegetation at night is crucial for analyzing its impact on the lights of the vehicle lane. If the light transmittance is too high, the lights of vehicles in the opposite lane may cause glare, affect the driver's line of sight, and reduce driving safety; while the light transmittance is too low, it may indicate that the vegetation is too dense or there are other problems, affecting the beauty and ecological function of the greening. The drone is equipped with a high-precision thermal imager, which can help identify the light transmittance of vegetation.

[0036] A2. Obtain the pavement maintenance inspection characteristics corresponding to each road section. The pavement maintenance inspection characteristics include the pavement disease area ratio, pavement flatness and pavement friction coefficient. The pavement disease area ratio, pavement flatness and pavement friction coefficient corresponding to each road section are input into the pavement maintenance analysis model, and the pavement maintenance characteristic value corresponding to each road section is output.

[0037] It should be noted that the road surface image is taken with the help of a high-resolution optical camera carried by a drone, cracks are identified through an image analysis algorithm, and the length and width of the cracks are calculated, and then the proportion of the crack area to the total road surface area is obtained. The road elevation data is obtained through the laser scanning equipment installed on the drone, and the IRI value is obtained based on the quarter-car simulation method. The IRI value is recorded as the road surface flatness. The drone can be equipped with a special friction coefficient measurement device to slide on the road surface for measurement. It can also be indirectly estimated by the road surface texture depth. The texture depth can be obtained by taking images with a high-precision camera carried by the drone. A common method for calculating texture depth is based on digital image processing technology. First, the captured road surface image is grayed and the color image is converted into a grayscale image to simplify subsequent calculations. Then, edge detection algorithms such as the Sobel operator and the Canny operator are used to extract the edge information of the road surface texture. By analyzing this edge information, the approximate values ​​of the texture spacing and depth can be calculated, and the approximate values ​​are recorded as the road surface friction coefficient.

[0038] A3. Obtain the facility maintenance inspection characteristics corresponding to each road section. The facility maintenance inspection characteristics include the facility integrity rate, facility cleanliness and facility function normality rate. The facility integrity rate, facility cleanliness and facility function normality rate corresponding to each road section are input into the pavement maintenance analysis model, and the facility maintenance characteristic value corresponding to each road section is output.

[0039] It should be noted that the images taken by drones are used to identify the integrity of traffic signs, such as whether they are damaged or faded, and the clarity and length of the markings. The proportion of damaged or unclear signs and markings to the total number of facilities is counted. For reflective materials on traffic signs, markings and guardrails, drones are used to take photos under specific lighting conditions to measure the reflective intensity. The proportion of reflective intensity close to the standard value is used as an indicator of cleanliness. The illumination sensor carried by the drone is used to measure the light intensity of street lamps at night, and the proportion of street lamps whose light intensity meets the design standards to the total number of street lamps is counted.

[0040] It should also be noted that the analysis process of the greening maintenance characteristic values ​​corresponding to each road section is as follows: the vegetation coverage rate, vegetation deviation value and night vegetation transmittance corresponding to each road section are normalized, and the vegetation coverage rate, vegetation deviation value and night vegetation transmittance corresponding to each road section after processing are recorded as , and , substitute into the analytical formula , and obtain the greening maintenance characteristic value corresponding to each road section , , , They are respectively the weight coefficient corresponding to the set road section vegetation coverage rate, the weight coefficient corresponding to the vegetation deviation value, and the weight coefficient corresponding to the night vegetation transmittance. g represents the number corresponding to each road section, and g is a positive integer.

[0041] It should also be noted that the analysis process of the pavement maintenance characteristic values ​​corresponding to each road section is as follows: the pavement disease area ratio, pavement flatness and pavement friction coefficient corresponding to each road section are normalized, and the pavement disease area ratio, pavement flatness and pavement friction coefficient corresponding to each road section after processing are recorded as , and , substitute into the analytical formula , and obtain the pavement maintenance characteristic value corresponding to each road section , , , They are respectively the weight coefficient corresponding to the proportion of the pavement disease area of ​​the set road section, the weight coefficient corresponding to the pavement flatness, and the weight coefficient corresponding to the pavement friction coefficient.

[0042] It should be noted again that the analysis process of the facility maintenance characteristic values ​​corresponding to each road section is as follows: the facility integrity rate, facility cleanliness and facility function normality rate corresponding to each road section are normalized, and the facility integrity rate, facility cleanliness and facility function normality rate corresponding to each road section after processing are recorded as , and , substitute into the analytical formula , and obtain the facility maintenance characteristic value corresponding to each road section , , , They are respectively the weight coefficient corresponding to the intactness rate of the set road section facilities, the weight coefficient corresponding to the cleanliness of the facilities, and the weight coefficient corresponding to the normal function rate of the facilities.

[0043] Step 2: Assessment of maintenance urgency: Based on the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section, assess whether each road section needs maintenance. If each road section needs maintenance, analyze the maintenance urgency of each road section and allocate collaborative tasks among departments.

[0044] In a specific embodiment, the evaluation of whether each road section needs maintenance is performed, and the specific analysis process is as follows: the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section are respectively compared with the set greening maintenance value threshold, pavement maintenance value threshold and facility maintenance value threshold. If the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to a certain road section are all greater than the set greening maintenance value threshold, pavement maintenance value threshold and facility maintenance value threshold, then it is evaluated that the road section does not need maintenance; if as long as one of the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to a certain road section is less than or equal to the set greening maintenance value threshold, pavement maintenance value threshold and facility maintenance value threshold, then it is evaluated that the road section needs maintenance.

[0045] In a specific embodiment, the analysis of the maintenance urgency of each road section is performed as follows: the greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section are input into a road section maintainability assessment model, and the road section maintainability result is output.

[0046] The road section maintenance results include values ​​of 1 and -1. When the road section maintenance result of a road section is 1, it indicates that the corresponding road section maintenance of the road section is high. Conversely, when the road section maintenance result of a road section is -1, it indicates that the corresponding road section maintenance of the road section is low.

[0047] In a specific embodiment, the road section maintainability assessment model is expressed as: , where represents the maintenance urgency result corresponding to the g-th road section, represents the maintenance urgency assessment value corresponding to the g-th road section, is the set maintenance urgency assessment value threshold, g represents the number corresponding to each road section, and g is a positive integer.

[0048] The greening maintenance value, pavement maintenance value and facility maintenance value corresponding to each road section are recorded as , and , substitute into the calculation formula Among them, , , They are the standard greening maintenance value, standard road surface maintenance value, and standard facility maintenance value corresponding to the set road section. , , They are respectively the weight factor corresponding to the set road section greening maintenance value, the weight factor corresponding to the road surface maintenance value, and the weight factor corresponding to the facility maintenance value.

[0049] It should be noted that , , Both are greater than 0 and less than 1.

[0050] It should also be noted that through the summary of a large amount of research data and experimental data, the standard greening maintenance value, standard pavement maintenance value, and standard facility maintenance value corresponding to the road section are set according to professional institutions and research institutions. At the same time, based on the professional knowledge and research basis of experts in the field, and discussed and confirmed with industry organizations or professional institutions, the experts set the weight factors corresponding to the greening maintenance value of the road section, the weight factors corresponding to the pavement maintenance value, and the weight factors corresponding to the facility maintenance value according to their own experience and knowledge.

[0051] In a specific embodiment, the allocation of collaborative tasks among the departments is specifically analyzed as follows: B1. If the corresponding road section of a certain road section has a high maintainability, the traffic police department is first notified to close the road section as soon as possible, and traffic guidance signs and signal lights are set in advance to guide vehicles to divert in an orderly manner. After the closure of the road section is completed, the road administration department is notified to go to the road section. The road administration department evaluates the maintenance type, materials and personnel configuration of the road section, and compiles the evaluated maintenance type, materials and personnel configuration into a report and sends it to the maintenance department. The maintenance department allocates the number of suitable maintenance personnel corresponding to the current road section based on the maintenance type, materials and personnel configuration report evaluated by the road administration department, and goes to the road section for maintenance.

[0052] B2. If the corresponding road section of a certain road section has low maintainability, the traffic police department will be notified first to evaluate the traffic flow of the road section, and then the time period corresponding to the minimum traffic flow of the road section will be obtained. Subsequently, the traffic police department will use the time period corresponding to the minimum traffic flow of the road section as the maintenance period, and send the maintenance period to the road administration department. After the road administration department obtains the maintenance period, it will notify the road administration department personnel in advance to conduct an evaluation during the maintenance period. At the same time, the traffic police department will close the road section before the maintenance period arrives, and set up traffic guidance signs and signal lights in advance to guide vehicles to divert in an orderly manner. After the closure of the road section is completed, the road administration department will be notified to go to the road section. The road administration department will evaluate the maintenance type, materials and personnel configuration of the road section, and organize the evaluated maintenance type, materials and personnel configuration into a report and send it to the maintenance department. The maintenance department will allocate the number of suitable maintenance personnel corresponding to the current road section based on the maintenance type, materials and personnel configuration report evaluated by the road administration department, and go to the road section for maintenance.

[0053] The existing technology does not have a multi-dimensional maintenance characteristic value analysis. The existing technology may simply focus on individual problems such as road surface diseases or damage to traffic facilities, while ignoring other aspects such as greening maintenance. For example, poor growth of green vegetation may affect the ecological environment and driving vision of the highway, but in the absence of a systematic evaluation, it may not be taken seriously, resulting in a decline in the overall service quality of the highway, and it is difficult to accurately judge the maintenance needs and urgency of each section. This may lead to an unreasonable allocation of maintenance resources, such as wasting resources on sections with low maintenance needs, while sections that really need emergency maintenance are not handled in a timely manner.

[0054] In the prior art, there is a lack of effective information sharing platforms between departments such as road administration, traffic police, and maintenance construction units. For example, after inspectors discover road surface diseases, they may need to inform maintenance construction units through cumbersome telephone or document delivery. In this process, information may be delayed, lost or misunderstood, resulting in the inability to carry out maintenance work in a timely manner. There is no clear departmental collaborative task allocation process. When facing maintenance work, each department may not know their responsibilities and work order. For example, when it is necessary to urgently close a road section for maintenance, the traffic police department and the road administration department may cause work delays due to unclear responsibilities, or there may be duplication of work or poor connection in traffic diversion and on-site investigation. For different stages of maintenance work, such as preliminary preparation, construction process and finishing work, there is a lack of a unified coordination mechanism, resulting in ineffective coordination between departments. For example, at the end of the maintenance work, if the traffic restoration work of the traffic police department and the quality inspection work of the road administration department are not reasonably arranged, the road closure time may be extended, affecting the normal operation of traffic.

[0055] Step 3: Analysis of maintenance progress: When a road section is under maintenance, several collection time points are set to analyze the maintenance progress adaptation value corresponding to the road section at each collection time point, and then evaluate whether the maintenance progress corresponding to the road section at each collection time point is at the final maintenance progress.

[0056] In a specific embodiment, the maintenance progress adaptation value corresponding to the road section is analyzed at each collection time point, and the specific analysis process is as follows: first, the road administration department uploads the corresponding maintenance progress characteristics at each collection time point of the road section, and the maintenance progress characteristics include the maintenance task completion ratio, time progress deviation and remaining maintenance work time, and inputs the maintenance task completion ratio, time progress deviation and remaining maintenance work time corresponding to the road section at each collection time point into the maintenance progress analysis model, and outputs the maintenance progress adaptation value corresponding to the road section at each collection time point.

[0057] It should be noted that the completion rate is calculated based on the detailed maintenance task list prepared in advance by the road administration department. For example, for the road surface repair task of a section of road, the list clearly stipulates that 100 disease points need to be repaired. During the work process, the maintenance personnel will record each completed repair. By dividing the number of disease points that have been repaired (such as 30 completed) by the total number of tasks (100), the maintenance task completion rate (30%) can be obtained. The maintenance personnel need to record the actual start time and expected start time of each task, as well as the actual completion time and expected completion time. For example, the guardrail cleaning work of a certain section of road is planned to start at 9 am and is expected to be completed at 11 am, but it actually started at 10 am and was completed at 12 pm. Then the deviation between the actual start time and the expected start time is 1 hour, and the deviation between the actual completion time and the expected completion time is 1 hour. By calculating the ratio of these differences to the total task plan duration, the time progress deviation can be obtained. The maintenance personnel can estimate it based on the number and difficulty of the unfinished tasks combined with previous work experience. For example, for the remaining 70 road surface repair tasks, based on past experience, each repair takes an average of 30 minutes, so the remaining maintenance work time is approximately 35 hours (70×0.5 hours).

[0058] In a specific embodiment, the evaluation of whether the maintenance progress corresponding to the road section at each collection time point is at the final maintenance progress is performed as follows: the maintenance progress adaptation value corresponding to the road section at each collection time point is compared with the standard final maintenance progress adaptation value set for the road section. If the maintenance progress adaptation value corresponding to the road section at a certain collection time point is the same as the standard final maintenance progress adaptation value set for the road section, it means that the maintenance progress corresponding to the road section at the collection time point is at the final maintenance progress.

[0059] Step 4: Allocation of collaborative tasks among departments: When the maintenance progress of the road section at a certain collection time point is at the final maintenance progress, the tasks of each department are then allocated.

[0060] In a specific embodiment, the collaborative tasks of various departments are deployed, and the specific analysis process is as follows: D1. When the maintenance progress corresponding to the road section at a certain collection time point is at the final maintenance progress, the number of waiting vehicles and the number of maintenance inspections corresponding to the road section at the collection time point are obtained, and the number of waiting vehicles corresponding to the road section at the collection time point is compared with the number of waiting vehicles corresponding to each number of evacuated personnel of the traffic police department. If the number of waiting vehicles corresponding to the road section at the collection time point is the same as the number of waiting vehicles corresponding to a certain number of evacuated personnel of the traffic police department, then the number of evacuated personnel of the traffic police department is recorded as the number of evacuated personnel of the traffic police department corresponding to the road section at the collection time point, and the number of evacuated personnel of the traffic police department corresponding to the road section at the collection time point is sent to the traffic police department, and the traffic police department deploys the corresponding number of evacuated personnel to the road section.

[0061] D2. Compare the number of maintenance inspections corresponding to the road section at the collection time point with the number of maintenance inspections corresponding to the number of inspectors of the road administration department. If the number of maintenance inspections corresponding to the road section at the collection time point is the same as the number of maintenance inspections corresponding to a certain number of inspectors of the road administration department, then record the number of inspectors of the road administration department as the number of inspectors of the road administration department corresponding to the road section at the collection time point, and send the number of inspectors of the road administration department corresponding to the road section at the collection time point to the road administration department, and the road administration department will deploy the corresponding number of inspectors to the road section.

[0062] Existing technologies may lack real-time monitoring means for maintenance progress, and cannot accurately grasp the progress of each road section during the maintenance process. For example, the progress can only be understood through regular reports from maintenance construction units, but such reports may be untimely or inaccurate, making it difficult to detect delays or other problems in time. The unreasonable allocation of departmental tasks at the final stage may result in insufficient traffic diversion personnel in the traffic police department, leading to traffic congestion; or too many inspection personnel in the road administration department, resulting in waste of resources. Failure to accurately allocate personnel based on the actual number of vehicles waiting to pass and maintenance inspection needs is not conducive to the smooth completion of maintenance work and the rapid recovery of traffic.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined in this specification, they shall all fall within the protection scope of the present invention.
