In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present application.

[0033] The block diagrams shown in the drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0034] The flowcharts shown in the drawings are only exemplary illustrations and do not necessarily include all contents and operations / steps, nor are they necessarily executed in the described order. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined. Therefore, the actual execution order may change according to the actual situation.

[0035] Figure 1 The schematic diagram shows an exemplary system architecture to which the technical solution of the embodiment of the present application can be applied.

[0036] As Figure 1 shown, the system architecture may include terminal devices (such as Figure 1 one or more of the smart phone 101, tablet computer 102, and portable computer 103 shown, and of course it can also be a desktop computer, etc.), network 104, and server 105. The network 104 is used to provide a medium for the communication link between the terminal device and the server 105. The network 104 may include various connection types, such as wired communication links, wireless communication links, etc.

[0037] It should be understood that Figure 1 the numbers of terminal devices, networks, and servers in

[0038] In one embodiment of the present application, as Figure 1 shown, the terminal device 101 sends a query request for the road maintenance cycle to the server 105. After receiving the query request, the server 105 first obtains the expected value of the road maintenance cycle and the expected value of the single vehicle mass in the target area during the historical time period, and fits the first functional relationship between the road maintenance cycle and the single vehicle mass according to the expected value of the road maintenance cycle and the expected value of the single vehicle mass during the historical time period. Then, according to the average single vehicle mass of the roads in the target area within the set unit time, the target maintenance cycle of the roads in the target area is determined under the first functional relationship, and finally the determined target maintenance cycle is sent to the terminal device 101.

[0039] It should be noted that the method for determining the road maintenance cycle provided in the embodiments of the present application is generally executed by the server 105. Correspondingly, the device for determining the road maintenance cycle is generally arranged in the server 105. However, in other embodiments of the present application, the terminal device may also have a similar function to the server, so as to execute the road maintenance cycle determination solution provided in the embodiments of the present application.

[0040] It should also be noted that, in addition to being executed by the aforementioned server 105 or terminal device, the method for determining the road maintenance cycle provided in the embodiments of the present application can also be executed by a cloud server with cloud computing capabilities.

[0041] Specifically, cloud computing is a computing model that distributes computing tasks across a resource pool composed of a large number of computing devices, enabling various application systems to obtain computing power, storage space, and information services as needed. The network that provides resources is called the "cloud". The resources in the "cloud" seem to the user to be infinitely expandable and can be obtained at any time, used on demand, and expanded at any time. By establishing a cloud computing resource pool (abbreviated as a cloud platform, generally referred to as an IaaS (Infrastructure as a Service) platform), various types of virtual resources are deployed in the resource pool for external customers to select and use. The cloud computing resource pool mainly includes: computing devices (virtual machines containing operating systems), storage devices, and network devices.

[0042] The implementation details of the technical solutions in the embodiments of the present application are elaborated in detail below:

[0043] Figure 2 The flowchart of the method for determining the road maintenance cycle according to an embodiment of the present application is shown. This method for determining the road maintenance cycle can be executed by a device with computing and processing capabilities, such as being executed by Figure 1 the server 105 shown in Figure 1 or being executed by Figure 2 the terminal device shown in

[0044] In step 210, obtain the expected value of the road maintenance cycle in the target area during the historical time period.

[0045] In the present application, the target area may refer to an administrative area (such as a county or a town), or may refer to a jurisdiction area managed by the traffic management department, or may refer to a road cluster area managed by the road maintenance party.

[0046] In the present application, the historical time period may refer to one year, one month, or one week in history. It should be noted that there should be multiple historical time periods, where one historical time period corresponds to an expected value of the road maintenance cycle. For example, the expected value of the road maintenance cycle for each month of the 12 months in 2019 in the target area can be obtained.

[0047] In the present application, the expected value of the road maintenance cycle may refer to the overall expected value of the maintenance cycles of various types of roads in the target area. Among them, the various types of roads may include any combination of 6 types of roads (expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other highways).

[0048] In an embodiment of the present application, obtaining the expected value of the road maintenance cycle in the target area during the historical time period can be implemented through Figure 3 the steps shown.

[0049] See Figure 3 , which shows a detailed flowchart of obtaining the expected value of the road maintenance cycle in the target area during the historical time period according to an embodiment of the present application. Specifically, it includes steps 211 to 213:

[0050] Step 211, obtaining the proportion of the number of various types of roads in the target area during the historical time period relative to the total number of roads.

[0051] Step 212, obtaining the historical road maintenance cycles of the various types of roads in the target area during the historical time period.

[0052] Step 213, determining the expected value of the road maintenance cycle in the target area during the historical time period based on the number of roads and the historical road maintenance cycles.

[0053] To enable those skilled in the art to better understand the above embodiments, a specific example will be used for auxiliary explanation below:

[0054] Region A contains 6 types of roads, namely expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other highways. Now it is necessary to obtain the expected value of the road maintenance cycle for each month of the 12 months in 2019 in Region A.

[0055] In the first step, obtain the proportion of the number of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in Area A in January 2019 to the total number of roads in Area A in January 2019. Among them, use q1, q2, q3, q4, q5, and q6 to represent the proportion of the number of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in January 2019 respectively.

[0056] In the second step, obtain the historical road maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in Area A in January 2019. Among them, use T1, T2, T3, T4, T5, and T6 to represent the historical road maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in January 2019 respectively.

[0057] In the third step, through formula 1:

[0058] "q1×T1 + q2×T2 + q3×T3 + q4×T4 + q5×T5 + q6×T6"

[0059] Calculate the expected value of the road maintenance cycle in Area A in January 2019.

[0060] Repeat the above first step, second step, and third step. Finally, obtain the expected values of the road maintenance cycles for each month from January to December 2019 in Area A, represented by H1, H2, H3, H4, H5, H6, H7, H8, H9, H10, H11, and H12 respectively.

[0061] It should be noted that when implementing the above steps 211 and 212, there is no sequential order between steps 211 and 212, that is, step 211 can be implemented first and then step 212, or step 212 can be implemented first and then step 211.

[0062] Continue to refer to Figure 2 , in step 230, obtain the expected value of the single-vehicle mass in the target area during the historical time period.

[0063] In this application, the expected value of the single-vehicle mass may refer to the overall expected value of the single-vehicle mass of various types of vehicles and overloaded vehicles in the target area. Among them, the various types of vehicles may include any combination of 4 types of vehicles (large vehicles, medium-sized vehicles, small vehicles, and micro vehicles).

[0064] In an embodiment of this application, obtaining the expected value of the single-vehicle mass in the target area during the historical time period can be implemented through the steps shown in Figure 4 shown.

[0065] See Figure 4 , which shows a detailed flowchart of obtaining the expected value of the single-vehicle mass of the target area during the historical time period according to an embodiment of the present application. Specifically, it includes steps 231 to 233:

[0066] Step 231, obtain the proportion of the number of various types of vehicles within the target area during the historical time period relative to the total number of vehicles, and the historical average mass of the various types of vehicles under non-overloading conditions.

[0067] Step 232, obtain the proportion of the number of overloaded vehicles of the various types of vehicles within the target area during the historical time period relative to the number of vehicles of the corresponding type, and the historical average overloaded mass of the various types of overloaded vehicles.

[0068] Step 233, determine the expected value of the single-vehicle mass of the target area during the historical time period based on the proportion of the number of vehicles, the historical average mass, the proportion of the number of overloaded vehicles, and the historical average overloaded mass.

[0069] To enable those skilled in the art to better understand the above embodiments, the following will be assisted by a specific example:

[0070] There are 4 types of vehicles including large vehicles, medium-sized vehicles, small vehicles, and micro vehicles traveling in Area A. Now it is necessary to obtain the expected value of the single-vehicle mass of Area A for each month in 2019.

[0071] First step, respectively obtain the proportion of the number of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles traveling in Area A in January 2019 relative to the total number of vehicles traveling in Area A in January 2019. Among them, p1, p2, p3, and p4 are respectively used to represent the proportion of the number of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles in January 2019. In addition, the historical average mass of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles traveling in Area A in January 2019 under non-overloading conditions is also respectively obtained. Among them, m1, m2, m3, and m4 are respectively used to represent the historical average mass of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles in January 2019.

[0072] In the second step, obtain the overloading ratios of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles traveling in Area A in January 2019, respectively, with respect to the number of vehicles of the corresponding types traveling in Area A in January 2019. Among them, use w1, w2, w3, and w4 to represent the overloading ratios of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles in January 2019, respectively. In addition, obtain the historical average overloading masses of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles traveling in Area A in January 2019, respectively. Among them, use u1, u2, u3, and u4 to represent the historical average overloading masses of large vehicles, medium-sized vehicles, small vehicles, and micro vehicles in January 2019, respectively.

[0073] In the third step, through Formula 2:

[0074] Calculate the expected value of the single-vehicle mass in Area A in January 2019 by "p1×(m1 + u1w1)+p2×(m2 + u2w2)+p3×(m3 + u3w3)+p4×(m4 + u4w4)".

[0075] Repeat the above first step, second step, and third step. Finally, obtain the expected values of the single-vehicle mass for each month from January to December 2019 in Area A, and use E1, E2, E3, E4, E5, E6, E7, E8, E9, E10, E11, and E12 to represent them respectively.

[0076] It should be noted that when implementing the above Step 231 and Step 232, there is no sequence between Step 231 and Step 232, that is, Step 231 can be implemented first and then Step 232, or Step 232 can be implemented first and then Step 231.

[0077] Continue to refer to Figure 2 , in Step 250, according to the expected value of the road maintenance cycle and the expected value of the single-vehicle mass within the historical time period, fit the first functional relationship between the road maintenance cycle and the single-vehicle mass.

[0078] In an embodiment of the present application, it may be to fit the first functional relationship between the road maintenance cycle and the single-vehicle mass by the least squares method according to the expected value of the road maintenance cycle and the expected value of the single-vehicle mass within the historical time period

[0079] In an embodiment of the present application, it may be to fit the first functional relationship between the road maintenance cycle and the single-vehicle mass by the MTLAB mathematical toolbox according to the expected value of the road maintenance cycle and the expected value of the single-vehicle mass within the historical time period

[0080] For example, in the example described in step 230, it may be based on the expected values of the road maintenance cycles H1, H2, H3, H4, H5, H6, H7, H8, H9, H10, H11, H12) for each month from January to December 2019 in region A and the expected values of the single-vehicle mass (E1, E2, E3, E4, E5, E6, E7, E8, E9, E10, E11, E12) to fit the first functional relationship between the road maintenance cycle and the single-vehicle mass: H = f1(E).

[0081] Continue to refer to Figure 2 , in step 270, according to the average single-vehicle mass of the roads in the target area within the set unit time, the target maintenance cycle of the roads in the target area is dynamically determined under the first functional relationship.

[0082] In this application, the average single-vehicle mass within the set unit time may refer to the average single-vehicle mass within the unit time of the current stage set, or may refer to the average single-vehicle mass within the unit time set in the future.

[0083] For example, for the average single-vehicle mass within the set unit time being the average single-vehicle mass within the unit time set in the future, specifically, it may be to statistically calculate the average mass of the vehicles passing through the target area within the next unit time (optionally one day or one month).

[0084] Specifically, when statistically calculating the average mass of the vehicles passing through the target area within the next unit time, the total mass and total number of the vehicles passing through the target area may be first statistically calculated, and then the average is obtained to get the average vehicle mass.

[0085] In an embodiment of this application, dynamically determining the target maintenance cycle of the roads in the target area under the first functional relationship may be implemented through Figure 5 the steps shown.

[0086] See Figure 5 , which shows the detailed flowchart of dynamically determining the target maintenance cycle of the roads in the target area under the first functional relationship according to an embodiment of this application. Specifically, it includes steps 271 to 273:

[0087] Step 271, through the first functional relationship, calculate the recommended maintenance cycle of the roads in the target area corresponding to the average single-vehicle mass.

[0088] Specifically, for example, in the example described in step 230, if the average single vehicle mass of the roads in area A within the set unit time is E_real, then through the first functional relationship H = f1(E), calculate the recommended maintenance period H_real = f1(E_real) of the roads in area A corresponding to the average single vehicle mass E_real.

[0089] Step 272, obtain the mandatory maintenance periods corresponding to various types of roads within the target area.

[0090] Specifically, continuing to refer to the example described in step 230, it can be to obtain the mandatory maintenance periods of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other highways in area A respectively. Among them, use Q1, Q2, Q3, Q4, Q5, Q6 to represent the mandatory maintenance periods of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other highways respectively.

[0091] Step 273, determine the target maintenance periods of various types of roads within the target area according to the magnitude relationship between the recommended maintenance period and the mandatory maintenance period.

[0092] In a specific implementation of an embodiment, determining the target maintenance periods of various types of roads within the target area according to the magnitude relationship between the recommended maintenance period and the mandatory maintenance period can be implemented through Figure 6 the solution shown.

[0093] See Figure 5 , which shows the detailed diagram of determining the target maintenance periods of various types of roads within the target area according to the magnitude relationship between the recommended maintenance period and the mandatory maintenance period according to an embodiment of the present application. Specifically, it includes steps 2731 to 2732:

[0094] Step 2731, when the mandatory maintenance period is less than the recommended maintenance period, determine the mandatory maintenance period as the target maintenance period.

[0095] Step 2732, when the mandatory maintenance period is not less than the recommended maintenance period, determine the recommended maintenance period as the target maintenance period.

[0096] Specifically, for example, in the example described in step 230, through the first function relationship H = f1(E), the recommended maintenance cycle H_real = f1(E_real) of the roads in area A corresponding to the average single-vehicle mass E_real is calculated. The mandatory maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are Q1, Q2, Q3, Q4, Q5, and Q6 respectively. Therefore, the target maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are min(H_real, Q1), min(H_real, Q2), min(H_real, Q3), min(H_real, Q4), min(H_real, Q5), and min(H_real, Q6) respectively.

[0097] In this application, the advantages of the above-described embodiments are as follows: The road maintenance cycle can be adjusted according to the average single-vehicle mass of the road within the set unit time, strengthening the rationality of determining the road maintenance cycle.

[0098] In an embodiment of this application, dynamically determining the target maintenance cycle of the roads in the target area under the first function relationship can be achieved through Figure 7 the steps shown below.

[0099] See Figure 7 , which shows a detailed flowchart of dynamically determining the target maintenance cycle of the roads in the target area under the first function relationship according to an embodiment of this application. Specifically, it includes steps 274 to 277:

[0100] Step 274, obtain the importance factors corresponding to various types of roads in the target area, where the importance factors are used to characterize the importance degree of the roads.

[0101] Specifically, for example, in the example described in step 230, the importance factors v corresponding to expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are obtained respectively. Among them, the importance factors corresponding to expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are represented by v1, v2, v3, v4, v5, and v6 respectively (f1 > f2 > f3 > f4 > f5, and the greater the importance factor, the higher the importance degree of the road).

[0102] Step 275, through the first function relationship and the importance factors corresponding to various types of roads, calculate the recommended maintenance cycles of various types of roads in the target area corresponding to the average single-vehicle mass.

[0103] In a specific implementation of an embodiment, through the first functional relationship and the emphasis factors corresponding to various types of roads, the recommended maintenance cycles of various types of roads in the target area corresponding to the average single-vehicle mass can be calculated by Formula 3:

[0104] “H_real / v=f1(E_real) / v”

[0105] Calculate the recommended maintenance cycles of various types of roads in the target area corresponding to the average single-vehicle mass

[0106] If the average single-vehicle mass of the roads in Area A within a set unit time is E_real, then through the emphasis factors v1, v2, v3, v4, v5, v6 corresponding to various types of roads and the first functional relationship H = f1(E), the recommended maintenance cycles of the expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in Area A corresponding to the average single-vehicle mass E_real are H_real / v1, H_real / v2, H_real / v3, H_real / v4, H_real / v5, and H_real / v6 respectively.

[0107] Step 276, obtain the mandatory maintenance cycles corresponding to various types of roads in the target area.

[0108] Step 277, determine the target maintenance cycles of various types of roads in the target area according to the magnitude relationship between the recommended maintenance cycles and the mandatory maintenance cycles.

[0109] In a specific implementation of an embodiment, when the mandatory maintenance cycle is less than the recommended maintenance cycle, the mandatory maintenance cycle can be determined as the target maintenance cycle; when the mandatory maintenance cycle is not less than the recommended maintenance cycle, the recommended maintenance cycle can be determined as the target maintenance cycle.

[0110] Specifically, for example, in the example described in step 230, the recommended maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are H_real / v1, H_real / v2, H_real / v3, H_real / v4, H_real / v5, H_real / v6 respectively, while the mandatory maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are Q1, Q2, Q3, Q4, Q5, Q6 respectively. Therefore, the target maintenance cycles of expressways, first-class highways, second-class highways, third-class highways, fourth-class highways, and other roads in area A are min(H_real / v1, Q1), min(H_real / v2, Q2), min(H_real / v3, Q3), min(H_real / v4, Q4), min(H_real / v5, Q5), min(H_real / v6, Q6) respectively.

[0111] In the above implementation, by introducing the attention factor v to characterize the attention degree of different types of roads. And the larger the attention factor, the more attention is paid to the road, and the more frequent the maintenance should be. Therefore, the advantage of the above embodiment is that it can determine the maintenance cycle of the road according to the specific situation of the road, and further strengthen the rationality of determining the road maintenance cycle.

[0112] Figure 8 The flowchart of the road maintenance cycle determination method according to an embodiment of the present application is shown. This road maintenance cycle determination method can be executed by a device with computing and processing capabilities, such as can be executed by Figure 1 the server 105 shown in Figure 1 or can be executed by the terminal device shown in Figure 8 It can also be executed by a cloud server with cloud computing capabilities. Referring to

[0113] shown, this road maintenance cycle determination method at least includes steps 220 to 280:

[0113] In step 220, obtain the expected value of the road maintenance cycle in the target area during the historical time period.

[0114] In step 240, obtain the expected value of the single vehicle mass in the target area during the historical time period, and the traffic flow during the historical time period.

[0115] Specifically, for example, the traffic flows F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12 of each month from January to December 2019 in area A can be obtained respectively.

[0116] In step 260, according to the expected value of the road maintenance cycle, the expected value of the single vehicle mass, and the traffic flow within the historical time period, a second functional relationship between the road maintenance cycle, the single vehicle mass, and the traffic flow is fitted.

[0117] For example, as in the example described in step 230, it can be based on the expected values of the road maintenance cycles (H1, H2, H3, H4, H5, H6, H7, H8, H9, H10, H11, H12), the expected values of the single vehicle masses (E1, E2, E3, E4, E5, E6, E7, E8, E9, E10, E11, E12), and the traffic flows (F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12) of each month from January to December 2019 in area A to fit the second functional relationship between the road maintenance cycle and the single vehicle mass: H = f2(E, F).

[0118] In step 280, according to the average single vehicle mass and traffic flow of the roads within the target area within a set unit time, the target maintenance cycle of the roads within the target area is dynamically determined under the second functional relationship.

[0119] In Figure 8 the road maintenance cycle determination method shown, compared with Figure 2 the road maintenance cycle determination method shown, the concept of traffic flow is added when fitting the functional relationship. The advantage of this is that: it can make the factors considered when determining the road maintenance cycle more comprehensive, thereby further strengthening the rationality of determining the road maintenance cycle.

[0120] Based on the technical solution disclosed in the present application, the inventors of the present application obtained the experimental data shown in Table 1 through experiments on determining the road maintenance cycles in 3 target areas.

[0122] Table 1

[0123] As shown in Table 1, by applying the technical solution provided in the present application to the scenario of determining the road maintenance cycle, compared with the prior art, determining the road maintenance cycle through the technical solution of the present application can reduce the road maintenance cost and at the same time reduce the number of traffic obstacles on the road. It can be seen that the road maintenance cycle determination scheme provided in the present application is superior to the prior art and can strengthen the rationality of determining the road maintenance cycle.

[0124] In the technical solutions provided by some embodiments of the present application, the first functional relationship between the road maintenance cycle and the single vehicle mass is fitted based on the expected value of the road maintenance cycle and the expected value of the single vehicle mass in the target area during the historical time period. Based on the average single vehicle mass in the target area during the set unit time period, the target maintenance cycle of the road in the target area is dynamically determined through the first functional relationship. Since the present application takes into account the historical situation of road maintenance and the historical situation of passing vehicles when determining the target maintenance cycle of the road in the target area, and can adjust the highway maintenance cycle according to the actual situation of the passing vehicles on the road, the determined road maintenance cycle conforms to the reality, thereby strengthening the rationality of determining the road maintenance cycle.
