[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0035] As shown in this specification and claims, unless the context clearly provides an example, the words "a", "an", "the", etc. do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0036] It is understood that the operations of each step are not necessarily performed precisely in order. Instead, the steps may be processed in reverse order or simultaneously. At the same time, other operations may be added to these processes, or one or more operations may be removed from these processes.

[0037] In order to fill the gaps and deficiencies in the prior art, this embodiment provides a public service supporting evaluation method applicable to urban physical examinations, the method comprising the following steps: S1. Obtain a plan map of the area to be evaluated, and determine the residential area and available blocks for the construction of public service facilities in the plan map. The area to be evaluated refers to the area where public service facilities need to be planned, and is usually based on urban districts. Residential areas can be marked in units of communities. Available blocks refer to areas that can be used to build public service facilities.

[0038] S2. Set location points in the available blocks and determine the shortest routes from each residential area to the location points.

[0039] S3. Obtain population distribution data of residential areas and determine the population distribution ratio of each residential area. The population distribution data can be obtained from demographic data or from population thermal distribution data. The population thermal distribution data can be obtained from GPS positioning signals, but is not limited thereto.

[0040] S4. Determine the distance measurement value between each residential area and the location point, where the distance measurement value = population distribution ratio × the length of the shortest route. That is, for a residential area, its corresponding distance measurement value is equal to the product of its own population distribution ratio and the length of the shortest route to the location point. The population distribution ratio can be expressed in percentage, but is not limited thereto.

[0041] S5. Adjust the position of the location point in the available plate so that the total value of the distance measurement values ​​of all residential areas is minimized, and use the corresponding location point as the location point.

[0042] S6. The location shall be used as a location for supporting public services.

[0043] Through the above design, the user experience of the people living around the public service facilities can be taken into account to the greatest extent possible, ensuring that the distance from each residential area to the public service facilities is controlled within a reasonable range. It can provide relevant reference data on the construction of public service facilities for urban planning and urban renewal, facilitate the improvement of the correlation between urban planning and urban renewal work and the actual life of the public, and optimize the improvement and enhancement effect of urban planning and urban renewal work on the actual life experience of the public.

[0044] In general, the public service support evaluation method suitable for urban physical examination provided in this embodiment can conduct a comprehensive evaluation of public service support according to the actual urban layout, help provide public service support plans that are more in line with the needs of the surrounding public, and is suitable for large-scale and large-volume urban planning and urban renewal, avoiding the waste of urban resources caused by inappropriate planning.

[0045] Specifically, in this embodiment, the public service supporting evaluation method applicable to urban physical examination also includes the following steps: S7. Construct a rectangular area in the plane map according to the planned construction area of ​​the public service facilities (i.e. the planned construction area), so that the size of the rectangular area matches the planned construction area of ​​the public service facilities. Among them, the rectangular area is all located in the available block, and the location point is ensured to be located in the rectangular area.

[0046] S8, determine the length of the shortest route in S2 within the rectangular area, that is, the length of the portion of the shortest route within the rectangular area. Figure 1 As shown, the intersection point of the shortest route s1 from a residential area to the reference point P and the boundary of the rectangular area D is d1, then the length of the area corresponding to this residential area is equal to the length of the line segment d1-P. For another example, the intersection point of the shortest route s2 from another residential area to the reference point P and the boundary of the rectangular area D is d2, then the length of the area corresponding to this residential area is equal to the length of the line segment d2-P. Calculate the distance correction value of the rectangular area, distance correction value = population distribution ratio × length in the area, that is, the distance correction value corresponding to a residential area is equal to the product of its population distribution ratio and the length of the area corresponding to it.

[0047] S9. Set the length and width range of the rectangular area, and adjust the shape of the rectangular area according to the length and width range to maximize the total distance correction value of all residential areas, and use the corresponding rectangular area as a reference range.

[0048] S10. Use the reference area as the plane layout of public service facilities.

[0049] Through the above design, a reference design for the plane layout of public service facilities can be provided. The reference design provided by S10 further reduces the distance for surrounding residents to reach public service facilities and improves convenience.

[0050] Furthermore, the public service supporting evaluation method applicable to urban physical examination also includes the following steps: S11. Determine the intersection points of all the shortest routes with the boundary of the reference range, and place unit weight points at each intersection. The number of unit weight points at each intersection is proportional to the population distribution ratio of the corresponding shortest route. Figure 1For example, d1 and d2 are the intersections of the shortest route s1 and the shortest route s2 with the boundary of the reference range, respectively. Then, the unit weight points are placed at the intersection d1 and the intersection d2, respectively. For the unit weight points at the intersection d1, these unit weight points all coincide with the intersection d1. For the unit weight points at the intersection d2, these unit weight points all coincide with the intersection d2. At the intersection d1, the number of placed unit weight points matches the population distribution ratio of the residential area corresponding to the shortest route s1. At the intersection d2, the number of placed unit weight points matches the population distribution ratio of the residential area corresponding to the shortest route s2. Exemplarily, if the population distribution ratio of the residential area corresponding to the shortest route s1 is 30% and the population distribution ratio of the residential area corresponding to the shortest route s2 is 20%, 30 unit weight points can be placed at the intersection d1 and 20 unit weight points can be placed at the intersection d2, and it is not limited thereto.

[0051] S12, performing cluster analysis on the unit weight points on the boundary of the reference range to obtain a clustering result. The clustering result includes clusters of the unit weight points.

[0052] S13. The number of clusters in the clustering result is used as a reference number of gates for public service facilities. That is, it can be used as a reference for the number of gates for public service facilities.

[0053] On the other hand, the public service supporting assessment method applicable to urban physical examination also includes the following steps: S14. Set the gate width of the public service facilities, and construct a reference line segment along the boundary of the reference range according to the gate width. The length of the reference line segment matches the gate width. The reference line segment is constructed along the boundary line of the reference range. If the boundary line at the corresponding position is a straight line, then the reference line segment is a straight line. Figure 2 If the corresponding position is a corner position, and the boundary line here is a 90-degree bent line, then the reference line segment is the broken line, such as Figure 3 As shown in the reference line segment L2.

[0054] S15. In each cluster, move the reference line segment within the boundary range of the reference range corresponding to the cluster to maximize the number of unit weight points on the reference line segment, and use the corresponding reference line segment as a gate indicator line.

[0055] S16. Use the gate indicator line as the reference position of the gate for public service facilities.

[0056] Through the above design, the reference results of the number of gates and the location of the gates can be obtained at the same time, realizing the overall planning suggestions of public service facilities from site selection, plane layout, number of gates selection, and gate location, further improving the effectiveness of public service facilities in covering the surrounding residents, and also helping to improve the user experience of the residents when using public service facilities.

[0057] It should be noted that in S2, an upper threshold of the shortest route can be set to prevent people from traveling too far to public service facilities.

[0058] It should be noted that public service facilities include but are not limited to: schools and hospitals. Public service facilities can also be of other types.

[0059] This embodiment also provides a public service supporting evaluation system applicable to urban physical examinations, the system comprising: a memory and a processor.

[0060] The memory stores a computer program, which is configured to execute the above-mentioned public service supporting evaluation method applicable to urban physical examinations when running.

[0061] The processor is configured to execute the above-mentioned public service supporting evaluation method applicable to urban physical examination through a computer program.

[0062] To sum up, the public service support evaluation method suitable for urban physical examination provided by the embodiment of the present invention can comprehensively evaluate the public service support according to the actual urban layout, help provide public service support plans that are more in line with the needs of the surrounding public, and is suitable for large-scale and large-volume urban planning and urban renewal, avoiding the waste of urban resources caused by inappropriate planning.
