Description

Technical Field

[0001] This disclosure relates to the field of road engineering, and more particularly to a road section maintenance method and electronic equipment. Background Technology

[0002] Highway networks are a vital national infrastructure, and their maintenance and management is a complex and costly systemic project. To effectively allocate limited maintenance funds and ensure the service level of the road network, traffic management departments commonly employ technologies such as pavement management systems to systematically monitor and assess road conditions, supporting maintenance decisions. These systems, through high-density data collection and analysis of the road network, can generate detailed maintenance needs lists in smaller units (e.g., every 100 meters or every kilometer), accurately identifying specific road sections requiring different types of maintenance measures (such as routine maintenance, preventative maintenance, functional repair, and structural repair).

[0003] This model, based on meticulous assessment, has led to a prominent problem in practice: the maintenance demand plans generated are often highly fragmented. That is, the plans include numerous short, geographically dispersed, and discontinuous maintenance sections. Organizing maintenance work directly based on such fragmented plans results in a series of problems, such as the frequent relocation of construction teams and large equipment between different work sites, significantly increasing mobilization and withdrawal costs. Multiple scattered work areas complicate traffic control schemes and exacerbate disruptions to public travel. Simultaneously, the difficulty and cost of project management also increase accordingly. Summary of the Invention

[0004] In view of this, the purpose of this disclosure is to propose a road maintenance method and electronic equipment to solve or partially solve the above-mentioned problems.

[0005] For the purposes described above, the first aspect of this disclosure provides a road section maintenance method, comprising: Obtain the length of each road segment in the road section to be maintained, and regard the road segments whose length is less than a preset length threshold as scattered road segments; For each scattered road segment, identify the first road segment and the second road segment adjacent to the scattered road segment, obtain the first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segment, and determine the target merging type and the target road segment based on the first road segment data, the second road segment data, and the target road segment data; The target road segment is merged with the scattered road segments to obtain a merged road segment; Obtain the first maintenance type corresponding to the target road segment and the second maintenance type corresponding to the scattered road segments, determine the target maintenance type based on the first maintenance type and the second maintenance type, and perform maintenance on the merged road segment according to the target maintenance type.

[0006] Based on the same inventive concept, a second aspect of this disclosure proposes a road maintenance device, comprising: The road segment identification module is configured to obtain the road segment length corresponding to each road segment data in the road segment to be maintained, and to regard the road segment data whose length is less than a preset length threshold as scattered road segments. The merge type determination module is configured to, for each scattered road segment, determine the first road segment and the second road segment adjacent to the scattered road segment, obtain the first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segment, and determine the target merge type and the target road segment based on the first road segment data, the second road segment data, and the target road segment data; The road segment merging module is configured to merge the target road segment with the scattered road segments to obtain a merged road segment; The road segment maintenance module is configured to obtain a first maintenance type corresponding to the target road segment and a second maintenance type corresponding to the scattered road segments, determine a target maintenance type based on the first maintenance type and the second maintenance type, and perform maintenance on the merged road segment based on the target maintenance type.

[0007] Based on the same inventive concept, a third aspect of this disclosure proposes an electronic device including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method described above when executing the computer program.

[0008] Based on the same inventive concept, a fourth aspect of this disclosure provides a non-transitory computer-readable storage medium that stores computer instructions for causing a computer to perform the methods described above.

[0009] As can be seen from the above, this disclosure proposes a road segment maintenance method and electronic device. It obtains the road segment length corresponding to each road segment data in the road segment to be maintained, and identifies road segment data with lengths less than a preset length threshold as scattered road segments. For each scattered road segment, it determines a first road segment and a second road segment adjacent to the scattered road segment, obtains the first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segment, and determines the target merging type and the target road segment based on the first road segment data, the second road segment data, and the target road segment data. It then merges the target road segment with the scattered road segment to obtain a merged road segment. By merging scattered road segments with their adjacent first or second road segments to obtain a merged road segment, it avoids the need to perform corresponding maintenance measures separately on multiple scattered road segments, thereby enabling fragmented planning and organization of maintenance construction and reducing the inconvenience of road maintenance for public travel. The process involves obtaining the first maintenance type corresponding to the target road segment and the second maintenance type corresponding to the scattered road segments. A target maintenance type is then determined based on these two types, and maintenance is performed on the merged road segment according to the target maintenance type. By comparing the required maintenance types of the scattered road segments with those of the road segments they are merging with, the target maintenance type for both the merged scattered road segments and the target road segment is ultimately determined. Maintenance is then performed on the merged road segment according to the target maintenance type, ensuring that the merged road segment can be planned, budgeted, and resource-allocated according to the most stringent operational requirements, thus improving the accuracy of road segment maintenance. Simultaneously, this significantly reduces the organizational and management costs of maintenance projects, minimizes the negative impact of maintenance construction on traffic operation, and enhances the scientific rigor, consistency, and overall quality of maintenance planning.

[0014] Highway networks are a vital national infrastructure, and their maintenance and management is a complex and costly systemic project. To effectively allocate limited maintenance funds and ensure the service level of the road network, traffic management departments commonly employ technologies such as Road Surface Management Systems (CPMS) to systematically monitor and assess road conditions, supporting maintenance decisions. These systems, through high-density data collection and analysis of the road network, can generate detailed maintenance requirement lists in smaller units (e.g., every 100 meters or every kilometer), accurately identifying specific road sections requiring different types of maintenance measures (such as routine maintenance, preventative maintenance, functional repair, and structural repair).

[0015] This model, based on meticulous assessment, has led to a prominent problem in practice: the maintenance demand plans generated are often highly fragmented. That is, the plans include numerous short, geographically dispersed, and discontinuous maintenance sections. Organizing maintenance work directly based on such fragmented plans results in a series of problems. Construction teams and large equipment need to be frequently moved between different work sites, significantly increasing mobilization and withdrawal costs. Multiple scattered work areas complicate traffic control schemes and exacerbate disruptions to public travel. Simultaneously, the difficulty and cost of project management also increase accordingly.

[0016] Based on the above description, this embodiment proposes a road section maintenance method, such as... Figure 1 As shown, the method includes: Step 101: Obtain the length of each road segment in the road section to be maintained, and designate road segments whose length is less than a preset length threshold as scattered road segments.

[0017] In practice, the road segment to be maintained is acquired. This road segment comprises multiple segments, meaning the lengths of these segments may be the same or different. Each segment has corresponding segment data, which includes at least one of the following: a unique identifier for the segment, segment name, segment type, segment code, starting point location, ending point location, material type, maintenance type, segment length, lane location, driving direction, environmental data, status data, and structural type.

[0018] In this embodiment, the road segment material type represents the structure and material properties of the road segment, specifically including the mixture type (asphalt / cement), surface layer thickness, and pavement structure bearing capacity. The road segment environmental data represents the environmental data of the road segment in service, specifically including the historical temperature distribution, average precipitation, and solar radiation flux of the area where the road segment is located. The road segment condition data includes the Pavement Condition Index (PCI), International Roughness Index (IRI), and corresponding cumulative equivalent axle loads (ESALs) measured over the years.

[0019] Obtain the length of each road segment and compare it with a preset length threshold. If the road segment length is less than the preset length threshold, the road segment is determined to be a fragmented road segment. If the road segment length is greater than the preset length threshold, the road segment is determined to be a non-fragmented road segment.

[0020] In this embodiment, if the road segment is determined to be a non-fragmented road segment, it can be maintained separately, that is, it does not need to be merged with other road segments.

[0021] Step 102: For each scattered road segment, determine the first road segment and the second road segment adjacent to the scattered road segment, obtain the first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segment, and determine the target merging type and the target road segment based on the first road segment data, the second road segment data, and the target road segment data.

[0022] In practice, after identifying scattered road segments, for each scattered road segment, a first road segment and a second road segment adjacent to the scattered road segment are determined. Specifically, the road segment identifier corresponding to the scattered road segment is obtained, and the identifier value corresponding to the road segment identifier is determined. The first identifier value and the second identifier value adjacent to the identifier value are obtained. The road segment corresponding to the first road segment identifier corresponding to the first identifier value is designated as the first road segment, and the road segment corresponding to the second road segment identifier corresponding to the second identifier value is designated as the second road segment.

[0023] For example, if the identifier value corresponding to the scattered road segment A is 10, then the road segments with identifier values ​​of 9 and 11 are obtained and used as the first road segment and the second road segment, respectively.

[0024] In this embodiment, if the road segments are sorted from smallest to largest according to the identifier values ​​corresponding to the road segment identifiers, then the first road segment is the road segment located to the left of the scattered road segments, that is, the first road segment is the road segment preceding the scattered road segments. The second road segment is the road segment located to the right of the scattered road segments, that is, the second road segment is the road segment following the scattered road segments.

[0025] Obtain the first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segments. Based on the first road segment data, the second road segment data, and the target road segment data, determine the target merging type and the target road segment.

[0026] In this embodiment, the target merging type is either left-side merging or right-side merging. If the target merging type is left-side merging, it means merging the preceding road segment with the scattered road segment, that is, merging the first road segment with the scattered road segment, and the target road segment is the first road segment. If the target merging type is right-side merging, it means merging the following road segment with the scattered road segment, that is, merging the second road segment with the scattered road segment, and the target road segment is the second road segment.

[0027] Step 103: Merge the target road segment with the scattered road segments to obtain a merged road segment.

[0028] In practice, after the target road segment is determined, it is merged with the scattered road segments, that is, the target road segment and the scattered road segments are merged into the same road segment, and then the same maintenance measures are taken for the target road segment and the scattered road segments.

[0029] In this embodiment, the length of the merged road segment is the sum of the length of the target road segment and the length of the scattered road segments.

[0030] Step 104: Obtain the first maintenance type corresponding to the target road segment and the second maintenance type corresponding to the scattered road segments; determine the target maintenance type based on the first maintenance type and the second maintenance type; and perform maintenance on the merged road segment based on the target maintenance type.

[0031] In practice, different road sections require different maintenance types. The first maintenance type corresponding to the target road section and the second maintenance type corresponding to the scattered road sections are obtained. A target maintenance type is determined based on the first and second maintenance types, and maintenance is performed on the merged road section according to the target maintenance type. The target maintenance type is one of the first and second maintenance types.

[0032] For each discrete road segment, the above-mentioned judgment and processing of whether to merge is performed is carried out until the judgment and processing of each discrete road segment is completed.

[0033] The above scheme obtains the road segment length corresponding to each road segment in the road section to be maintained, and road segments with lengths less than a preset length threshold are identified as scattered road segments. For each scattered road segment, a first road segment and a second road segment adjacent to the scattered road segment are determined. The first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segment are obtained. Based on the first road segment data, the second road segment data, and the target road segment data, the target merging type and the target road segment are determined. The target road segment is merged with the scattered road segment to obtain a merged road segment. By merging scattered road segments with their adjacent first or second road segments to obtain merged road segments, the need to perform corresponding maintenance measures separately on multiple scattered road segments is avoided. This fragmented planning and organization of maintenance construction reduces the inconvenience of road maintenance for public travel. The process involves obtaining the first maintenance type corresponding to the target road segment and the second maintenance type corresponding to the scattered road segments. A target maintenance type is then determined based on these two types, and maintenance is performed on the merged road segment according to the target maintenance type. By comparing the required maintenance types of the scattered road segments with those of the road segments they are merging with, the target maintenance type for both the merged scattered road segments and the target road segment is ultimately determined. Maintenance is then performed on the merged road segment according to the target maintenance type, ensuring that the merged road segment can be planned, budgeted, and resource-allocated according to the most stringent operational requirements, thus improving the accuracy of road segment maintenance. Simultaneously, this significantly reduces the organizational and management costs of maintenance projects, minimizes the negative impact of maintenance construction on traffic operation, and enhances the scientific rigor, consistency, and overall quality of maintenance planning.

[0034] In some embodiments, after determining the target maintenance type, a maintenance length threshold corresponding to the target maintenance type is determined. The merged road segment length corresponding to the merged road segment is determined, wherein the merged road segment length is the sum of the road segment length of the target road segment and the road segment length of the discrete road segment.

[0035] The length of the merged road segment is compared with a maintenance length threshold. If the length of the merged road segment is less than or equal to the maintenance length threshold, the merged road segment is maintained according to the target maintenance type. If the length of the merged road segment is greater than the maintenance length threshold, the current merge is terminated. The target merge type corresponding to the merged road segment is determined, and it is determined whether the preset conditions corresponding to another adjacent road segment other than the target road segment are met. Maintenance is performed on the discrete road segments based on the judgment result.

[0036] Specifically, if it is determined that the preset conditions corresponding to another adjacent road segment are met, then the other adjacent road segment is merged with the discrete road segment, and a new target maintenance type is determined. Similarly, the merged road segment length of the new merged road segment is compared with the maintenance length threshold corresponding to the new target maintenance type. If it is less than or equal to the maintenance length threshold corresponding to the new target maintenance type, then the new merged road segment is maintained according to the new target maintenance type. If it is still greater than the maintenance length threshold corresponding to the new target maintenance type, then the discrete road segment is maintained separately using the second maintenance type corresponding to the discrete road segment.

[0037] If it is determined that the preset conditions corresponding to another adjacent road segment are not met, then the discrete road segment will be maintained separately using the second maintenance type corresponding to the discrete road segment.

[0038] For example, the first road segment is road segment A, the discrete road segment is road segment B, and the second road segment is road segment C. The first maintenance type corresponding to road segment A is routine maintenance, the second maintenance type corresponding to road segment B is preventive maintenance, and the third maintenance type corresponding to road segment C is functional repair.

[0039] If the merged road segments are determined to be road segment A and road segment B, then the target maintenance type is preventative maintenance. The maintenance length threshold corresponding to preventative maintenance is determined to be 30 km. The sum of the lengths of road segments A and B is calculated, i.e., the length of the merged road segment is 35 km. At this point, the length of the merged road segment is greater than the maintenance length threshold, and it is determined whether the second preset condition for merging with the second road segment is met.

[0040] If the conditions are met, the new merged road segments will be identified as segment B and segment C, with the target maintenance type being functional repair. The maintenance length threshold corresponding to functional repair is determined to be 25 km. The sum of the lengths of segment B and segment C is calculated, resulting in a new merged road segment length of 23 km. Since the new merged road segment length is less than the new maintenance length threshold, segment B and segment C can be merged for maintenance, with the maintenance type being functional repair.

[0041] In some embodiments, the road segment data includes road segment type, road segment start location, and road segment end location. Step 102, which involves obtaining the first road segment data corresponding to the first road segment, the second road segment data corresponding to the second road segment, and the target road segment data corresponding to the scattered road segments, and determining the target merging type and target road segment based on the first road segment data, the second road segment data, and the target road segment data, specifically includes: Step 1021: Obtain the first road segment type and the end point of the first road segment corresponding to the first road segment, the second road segment type and the start point of the second road segment corresponding to the second road segment, and the target road segment type, the start point of the target road segment, and the end point of the target road segment corresponding to the scattered road segments; Step 1022: Determine the first distance between the end point of the first road segment and the starting point of the target road segment, and the second distance between the end point of the target road segment and the starting point of the second road segment; Step 1023: In response to satisfying the first preset condition but not satisfying the second preset condition, determine that the target merging type is left-side merging, and the target road segment is the first road segment; or, Step 1024: In response to the second preset condition being met but the first preset condition not being met, determine that the target merging type is right-side merging, and the target road segment is the second road segment; or, Step 1025: In response to satisfying both the first preset condition and the second preset condition, determine the first probability value corresponding to the left-side merging and the second probability value corresponding to the right-side merging, and determine the target merging type and target road segment based on the first probability value and the second probability value. The first preset condition is that the first road segment type is the same as the target road segment type and the first distance is less than or equal to a preset distance threshold. The second preset condition is that the second road segment type is the same as the target road segment type and the second distance is less than or equal to a preset distance threshold.

[0042] In specific implementation, the first road segment type and the end point of the first road segment, the second road segment type and the start point of the second road segment, the target road segment type, the start point of the target road segment, and the end point of the target road segment corresponding to the scattered road segments are obtained.

[0043] In this embodiment, the road segment type indicates the administrative level to which the road segment belongs. The road segment type includes national highways, provincial highways, county highways, township roads, or village roads.

[0044] Determine a first distance between the end point of the first road segment and the start point of the target road segment, and a second distance between the end point of the target road segment and the start point of the second road segment, wherein the first distance represents the distance between the end point of the first road segment and the start point of the discrete road segment, and the second distance represents the distance between the end point of the discrete road segment and the start point of the second road segment.

[0045] In this embodiment, the end point of the first road segment corresponds to a first end point station number, and the starting point of the discrete road segments corresponds to a target starting point station number. The distance between any two adjacent station numbers is a preset distance value. By calculating the difference between the first end point station number and the target starting point station number, and multiplying the difference by the preset distance value, the first distance between the end point of the first road segment and the starting point of the target road segment can be determined.

[0046] In this embodiment, the calculation method for the second distance is the same as that for the first distance, and will not be repeated here.

[0047] A first preset condition and a second preset condition are preset. The first preset condition is the condition corresponding to merging a first road segment with discrete road segments, and the second preset condition is the condition corresponding to merging a second road segment with discrete road segments. The first preset condition is that the type of the first road segment is the same as the type of the target road segment, and the first distance is less than or equal to a preset distance threshold. The second preset condition is that the type of the second road segment is the same as the type of the target road segment, and the second distance is less than or equal to a preset distance threshold.

[0048] In this embodiment, different maintenance types can be pre-defined as being able to be merged. Taking the merging of the first road segment and the discrete road segment as an example, if the target maintenance type corresponding to the discrete road segment cannot be merged with the first maintenance type corresponding to the first road segment, then the discrete road segment and the first road segment cannot be merged either.

[0049] In other words, the first and second preset conditions may further include whether maintenance types can be merged. Specifically, the first preset condition is that the first road segment type is the same as the target road segment type, the first distance is less than or equal to a preset distance threshold, and the first maintenance type and the target maintenance type can be merged. The second preset condition is that the second road segment type is the same as the target road segment type, the second distance is less than or equal to a preset distance threshold, and the second maintenance type and the target maintenance type can be merged.

[0050] In response to the condition that the first preset condition is met but the second preset condition is not met, that is, the condition for merging the discrete road segment with the first road segment is met but the condition for merging the discrete road segment with the second road segment is not met, the target merging type is determined to be left-side merging and the target road segment is the first road segment.

[0051] In response to the condition that the second preset condition is met but the first preset condition is not met, that is, the condition for merging the discrete road segment with the second road segment is met but the condition for merging the discrete road segment with the first road segment is not met, the target merging type is determined to be right-side merging and the target road segment is the second road segment.

[0052] In response to satisfying both the first and second preset conditions—that is, satisfying both the conditions for merging the discrete road segment with the first road segment and the conditions for merging the discrete road segment with the second road segment—further determination is needed based on other conditions to decide whether to merge the first or second road segment. Specifically, this involves determining the first probability value corresponding to merging on the left and the second probability value corresponding to merging on the right, and then determining the target merging type and target road segment based on the first and second probability values.

[0053] In this embodiment, if the discrete road segment is the beginning or end of the road segment to be repaired, then the road segment adjacent to the discrete road segment only exists as either the first road segment or the second road segment. If the discrete road segment is the beginning of the road segment to be repaired, then there is no preceding first road segment, only the second road segment. In this case, it is only necessary to determine whether the second preset condition is met. If it is met, the discrete road segment and the second road segment can be merged. If it is not met, then the discrete road segment, i.e., the second road segment, can be maintained separately.

[0054] In some embodiments, determining the first probability value corresponding to the left-side merging and the second probability value corresponding to the right-side merging in step 1025 specifically includes: Step 10251: Obtain the first road surface condition index corresponding to the first road segment, the second road surface condition index corresponding to the second road segment, and the target road surface condition index corresponding to the discrete road segment; Step 10252: Obtain the target road segment material type corresponding to the discrete road segment, and determine the target pavement performance retention factor based on the target road segment material type; Step 10253: Determine the first effective age of the discrete road segment based on the first road surface condition index, the target road surface condition index, and the target road surface performance retention factor; determine the second effective age of the discrete road segment based on the second road surface condition index, the target road surface condition index, and the target road surface performance retention factor. Step 10254: Determine the first maintenance resource data corresponding to the left-side merging and the second maintenance resource data corresponding to the right-side merging; Step 10255: Determine the first probability value corresponding to the left-side merging based on the first effective age and the first maintenance resource data, and determine the second probability value corresponding to the right-side merging based on the second effective age and the second maintenance resource data.

[0055] In specific implementation, the first pavement condition index corresponding to the first road segment, the second pavement condition index corresponding to the second road segment, and the target pavement condition index corresponding to the discrete road segment are obtained. In this embodiment, the pavement condition index can be obtained directly or determined according to a pavement performance degradation model. Specifically, taking the target pavement condition index corresponding to a discrete road segment as an example, the process of determining the target pavement condition index corresponding to a discrete road segment through a pavement performance degradation model includes: The pavement distress state, traffic load state, climate environment, and second maintenance type corresponding to the discrete road segment are obtained. The pavement distress state, traffic load state, climate environment, and second maintenance type are input into a pre-trained decay parameter determination model. After processing by the decay parameter determination model, the decay rate, structural damage inflection point, environmental aging weight coefficient, environmental aging acceleration factor, and target inversion parameters corresponding to the discrete road segment are output.

[0056] Wherein, the decay rate corresponding to the discrete road segment represents the degree of decay of the discrete road segment, the structural failure inflection point corresponding to the discrete road segment represents the time point at which the road segment structure is destroyed, and the target inversion parameter corresponding to the discrete road segment is used to fit the nonlinear characteristics of performance decay.

[0057] Obtain the historical pavement condition index for each road segment in the road section to be repaired. Iterate through all historical pavement condition indices to determine the maximum and minimum values. Based on the maximum and minimum pavement condition indices, the decay rate of the discrete road segment, the structural damage inflection point of the discrete road segment, the environmental aging weight coefficient of the discrete road segment, and the environmentally induced aging acceleration factor of the discrete road segment, determine the target pavement condition index for the discrete road segment according to the pavement performance decay model. The pavement performance decay model is expressed by the formula:

[0058] in, The target road surface condition index, This represents the minimum value of the road surface condition index. is the maximum value of the road surface condition index, t is the time difference between the current time and the road section construction time, a is the decay rate, and b is the structural failure inflection point. For environmental aging weighting coefficients, An environmental factor that accelerates aging.

[0059] Obtain the target road segment material type corresponding to the discrete road segment, search the database based on the target road segment material type, and determine the target pavement performance retention factor corresponding to the target road segment material type.

[0060] The first effective age of the discrete road segment is determined based on the first pavement condition index, the target pavement condition index, and the target pavement performance retention factor. The second effective age of the discrete road segment is determined based on the second pavement condition index, the target pavement condition index, and the target pavement performance retention factor. The first effective age represents the effective age of the discrete road segment after merging it with the first road segment for maintenance. The second effective age represents the effective age of the discrete road segment after merging it with the second road segment for maintenance.

[0061] Determine the first maintenance resource data corresponding to the left-side merging and the second maintenance resource data corresponding to the right-side merging, wherein the first maintenance resource data represents the maintenance cost required to merge the discrete road segment with the first road segment for maintenance, and the second maintenance resource data represents the maintenance cost required to merge the discrete road segment with the second road segment for maintenance.

[0062] The first probability value corresponding to the left-side merging is determined based on the first effective age and the first maintenance resource data, and the second probability value corresponding to the right-side merging is determined based on the second effective age and the second maintenance resource data.

[0063] In this embodiment, the first probability value and the second probability value are determined through a micro cooperative game model. Taking the first probability value as an example, the method for determining the first probability value specifically includes: Determine the first maintenance cost corresponding to the separate maintenance of the first road segment and the second maintenance cost corresponding to the separate maintenance of the discrete road segments. Add the first maintenance cost and the second maintenance cost to obtain the target maintenance resource data. Subtract the target maintenance resource data from the first maintenance resource data to obtain the maintenance resource data difference value. This maintenance resource data difference value represents the cost savings achieved by combining the maintenance of the first road segment and the discrete road segments compared to maintaining them separately.

[0064] After determining the initial effective age of the discrete road segments after separate maintenance, the difference between the first effective age and the initial effective age is calculated to obtain the effective age difference value. This effective age difference value represents the extended road segment age after merging the maintenance of the first road segment and the discrete road segments, compared to maintaining the first road segment and the discrete road segments separately.

[0065] The difference in maintenance resource data and the difference in effective age are input into the micro cooperative game model. After processing by the micro cooperative game model, the first probability value is output.

[0066] In some embodiments, step 10253, which involves determining the first effective age of a discrete road segment based on the first pavement condition index, the target pavement condition index, and the target pavement performance retention factor, and determining the second effective age of the discrete road segment based on the second pavement condition index, the target pavement condition index, and the target pavement performance retention factor, specifically includes: Step A: Determine a first average road surface condition index based on the first road surface condition index and the target road surface condition index; determine a second average road surface condition index based on the second road surface condition index and the target road surface condition index. Step B: Obtain the preset road age corresponding to the discrete road segment, and determine the first effective age corresponding to the discrete road segment based on the preset road age, the first average road surface condition index, and the target road surface performance retention factor. Step C: Determine the second effective age corresponding to the discrete road segment based on the preset road age, the second average road surface condition index, and the target road surface performance retention factor.

[0067] In specific implementation, a first average road surface condition index is determined based on the first road surface condition index and the target road surface condition index, that is, the first road surface condition index and the target road surface condition index are averaged to obtain the first average road surface condition index.

[0068] The second average road surface condition index is determined based on the second road surface condition index and the target road surface condition index, that is, the second road surface condition index and the target road surface condition index are averaged to obtain the second average road surface condition index.

[0069] Obtain the preset road age and target inversion parameters corresponding to the discrete road segment, wherein the target inversion parameters are parameters determined by the decay parameter determination model. Determine the first effective age of the discrete road segment based on the preset road age, the first average pavement condition index, and the target pavement performance retention factor. Determine the second effective age of the discrete road segment based on the preset road age, the second average pavement condition index, and the target pavement performance retention factor. The effective age is expressed by the formula:

[0070] in, The effective age period, i.e., the first effective age period or the second effective age period. To preset road age, For the target inversion parameters, The target pavement performance retention factor. It is the average road surface condition index, namely the first average road surface condition index or the second average road surface condition index.

[0071] In some embodiments, determining the first maintenance resource data corresponding to the left-side merging and the second maintenance resource data corresponding to the right-side merging in step 10254 specifically includes: Step a: Obtain the first segment length of the first road segment, the second segment length of the second road segment, and the target segment length corresponding to the discrete road segment; Step b: Determine the first preset maintenance type corresponding to the left-side merging and the second preset maintenance type corresponding to the right-side merging; Step c: Determine the first maintenance resource data corresponding to the left-side merging based on the first road segment length, the target road segment length, and the first preset maintenance type; determine the second maintenance resource data corresponding to the right-side merging based on the second road segment length, the target road segment length, and the second preset maintenance type.

[0072] In specific implementation, the first segment length of the first road segment, the second segment length of the second road segment, and the target segment length corresponding to the discrete road segment are obtained, and the first preset maintenance type corresponding to the left-side merging and the second preset maintenance type corresponding to the right-side merging are determined.

[0073] In this embodiment, the first initial maintenance type corresponding to the first road segment, the second initial maintenance type corresponding to the discrete road segment, and the third initial maintenance type corresponding to the second road segment are obtained. The first maintenance level corresponding to the first initial maintenance type, the second maintenance level corresponding to the second initial maintenance type, and the third maintenance level corresponding to the third initial maintenance type are determined.

[0074] The first maintenance level is compared with the second maintenance level. If the first maintenance level is greater than or equal to the second maintenance level, the first preset maintenance type corresponding to the left-side merging is determined to be the first initial maintenance type corresponding to the first road segment. If the first maintenance level is less than the second maintenance level, the first preset maintenance type corresponding to the left-side merging is determined to be the second initial maintenance type corresponding to the discrete road segment.

[0075] The second maintenance level is compared with the third maintenance level. If the second maintenance level is greater than or equal to the third maintenance level, the second preset maintenance type corresponding to the right-side merging is determined to be the second initial maintenance type corresponding to the discrete road segment. If the second maintenance level is less than the third maintenance level, the second preset maintenance type corresponding to the right-side merging is determined to be the third initial maintenance type corresponding to the discrete road segment.

[0076] Based on the length of the first road segment, the length of the target road segment, and the first preset maintenance type, the first maintenance resource data corresponding to the left-side merging is determined; based on the length of the second road segment, the length of the target road segment, and the second preset maintenance type, the second maintenance resource data corresponding to the right-side merging is determined. The maintenance resource data is expressed using the following formula:

[0077] in, This refers to maintenance resource data, specifically either primary maintenance resource data or secondary maintenance resource data. The combined road segment length is specifically the sum of the length of the first road segment and the length of the target road segment. For fixed maintenance costs per kilometer, This refers to the maintenance coefficient corresponding to either the first preset maintenance type or the second preset maintenance type. The maintenance cost corresponding to the first preset maintenance type per kilometer or the maintenance cost corresponding to the second preset maintenance type per kilometer.

[0078] In some embodiments, determining the target merging type and target road segment based on the first probability value and the second probability value in step 1025 specifically includes: Step 1025A: In response to the first probability value being greater than the second probability value, determine the target merging type as left-side merging, and the target road segment as the first road segment; or, Step 1025B: In response to the first probability value being less than the second probability value, determine the target merging type as right-side merging, and the target road segment as the second road segment; or, Step 1025C: In response to the first probability value being equal to the second probability value, obtain the first segment length of the first road segment and the second segment length of the second road segment, and determine the target merging type and target road segment based on the first segment length and the second segment length.

[0079] In practice, when both the conditions for merging the discrete road segment with the first road segment and the conditions for merging the discrete road segment with the second road segment are met, it is necessary to further determine whether to merge the first or second road segment based on other conditions. The first probability value corresponding to merging on the left and the second probability value corresponding to merging on the right are determined, and the first probability value and the second probability value are compared.

[0080] If the first probability value is greater than the second probability value, it indicates that the first road segment has a stronger attraction force. At this time, the target merging type is determined to be left-side merging, and the target road segment is the first road segment, that is, merging the discrete road segment with the first road segment.

[0081] If the first probability value is less than the second probability value, it indicates that the second road segment has a stronger attraction force. At this time, the target merging type is determined to be right-side merging, and the target road segment is the second road segment, that is, merging the discrete road segment with the second road segment.

[0082] If the first probability value equals the second probability value, then obtain the first segment length of the first road segment and the second segment length of the second road segment, and determine the target merging type and target road segment based on the first segment length and the second segment length.

[0083] Specifically, when the first probability value and the second probability value are the same, in order to further reduce fragmentation, road segments with longer lengths are preferentially selected for merging. That is, the target merging type and the target road segments are determined based on the lengths of the first and second road segments: Step 10a: In response to the first road segment length being greater than or equal to the second road segment length, determine the target merging type as left-side merging, and the target road segment as the first road segment; or, Step 10b: In response to the first road segment length being less than the second road segment length, the target merging type is determined to be right-side merging, and the target road segment is the second road segment.

[0084] In specific implementation, if the length of the first road segment is greater than or equal to the length of the second road segment, it means that the first road segment is longer than the second road segment. The target merging type is determined to be left-side merging, and the target road segment is the first road segment, that is, the discrete road segment is merged with the first road segment.

[0085] If the first road segment is shorter than the second road segment, it means that the second road segment is longer than the first road segment. The target merging type is determined to be right-side merging, and the target road segment is the second road segment, which means merging the discrete road segment with the second road segment.

[0086] In some embodiments, determining the target maintenance type based on the first maintenance type and the second maintenance type in step 105 specifically includes: Step 1051: Determine the first maintenance level corresponding to the first maintenance type and the second maintenance level corresponding to the second maintenance type; Step 1052: In response to the first maintenance level being greater than or equal to the second maintenance level, determine the target maintenance type as the first maintenance type; or, Step 1053: In response to the first maintenance level being lower than the second maintenance level, determine the maintenance type as the second maintenance type.

[0087] In specific implementation, the first maintenance level corresponding to the first maintenance type and the second maintenance level corresponding to the second maintenance type are determined. The maintenance level specifically includes routine maintenance, preventive maintenance, functional repair and structural repair, and the maintenance levels are ordered in priority as H (structural repair) > H (functional repair) > H (preventive maintenance) > H (routine maintenance).

[0088] The first maintenance level is compared with the second maintenance level. If the first maintenance level is greater than or equal to the second maintenance level, it means that the first maintenance level is higher. The target maintenance type is then determined to be the first maintenance type, that is, the merged road section is maintained using the first maintenance type.

[0089] If the first maintenance level is lower than the second maintenance level, it means that the second maintenance level is higher. The target maintenance type is determined to be the second maintenance type, that is, the merged road section is maintained using the second maintenance type.

[0090] In some embodiments, if a road segment is a special structure such as a bridge, it needs to be maintained separately, meaning it cannot be maintained in conjunction with adjacent road segments. Therefore, step 102 involves determining the first and second road segments adjacent to each scattered road segment, specifically including: Step 102A: For each scattered road segment, determine the corresponding structure type of the scattered road segment; Step 102B: In response to the structure type being a preset structure type, obtain the second maintenance type corresponding to the scattered road segments, and perform maintenance on the scattered road segments according to the second maintenance type; or, Step 102C: In response to the structure type being a type other than the preset structure type, determine the first road segment and the second road segment adjacent to the scattered road segment.

[0091] In practice, for each scattered road segment, the corresponding structure type is determined, wherein the structure type is used to describe the type of structure of the road segment.

[0092] If the structure type is a preset structure type, obtain the second maintenance type corresponding to the scattered road sections, and maintain the scattered road sections according to the second maintenance type, that is, maintain the scattered road sections separately. The preset structure type includes bridges, tunnels, special roadbeds, and test sections for the application of "four new technologies," etc. The special roadbed refers to road sections with special soil (rock), adverse geological conditions, or road sections located in environments with special climates and hydrological conditions, such as loess, landslides, and collapses. The test sections for the application of "four new technologies" are road sections using special processes such as cold-mix paving and on-site recycling.

[0093] If the structure type is other than the preset structure type, the subsequent merging steps can continue, that is, determine the first and second road segments adjacent to the scattered road segments, and then determine the specific target merging type and target road segments.

[0094] In this embodiment, special merging rules are set for road sections with preset structure types, allowing for holistic and consistent maintenance decisions for important structures. For example, when the preventive maintenance length of a bridge within the road network is less than a certain proportion of the total bridge length, the preventive maintenance road sections for that bridge are adjusted to routine maintenance.
