[0002] Urban planning management of building layout is an important part of ensuring the rational use of urban space, improving the quality of living environment, ensuring public safety and promoting sustainable development; it involves planning and design, land use planning, building control, urban traffic planning, environmental protection planning and public facilities planning.

[0003] Public facilities in building layout are a vital component of urban planning. They not only serve the daily needs of residents, but also have a profound impact on the functionality, aesthetics and sustainability of the city. They include educational facilities, medical and health facilities, cultural and entertainment facilities, and transportation facilities.

[0004] In the existing technology, the site selection of subway stations is a complex and crucial process. It not only needs to consider the distribution of passenger flow, but also needs to comprehensively evaluate multiple factors to ensure that the site setting can maximize the service to the public and promote the effective operation of the urban transportation system. However, in actual operation, the traditional method of collecting passenger flow distribution information mainly relies on manual analysis or empirical judgment, which has some obvious shortcomings, such as low efficiency, limited accuracy and limited coverage. Therefore, in order to overcome the above problems, it is necessary to use advanced information technology to improve the accuracy and efficiency of passenger flow data analysis in the process of subway station site selection.

[0007] As a further solution of the present invention: the process of setting the initial spacing distance includes: Obtain historical site selection data, which includes historical site selection points of other urban subway stations; obtain the distance between each adjacent historical site selection point according to the historical site selection data, and obtain the maximum value of all distances, and use the maximum value as the initial interval distance.

[0008] As a further solution of the present invention: the process of selecting a number of initial points on the route map according to the initial interval distance includes: The urban area is gridded according to the initial interval distance to obtain a plurality of grid points, and all route intersections on the route map are obtained; at each grid point, the route intersection closest to the grid point is selected and recorded as an initial point, thereby obtaining a plurality of initial points.

[0009] As a further solution of the present invention: the process of dividing the urban area into grids according to the initial interval distance is to use the initial interval distance as the distance between adjacent grid points in the grid.

[0010] As a further solution of the present invention: the process of obtaining the average daily flow of people includes: Obtain all entrances and exits in the building blocks on both sides of the corrected road section, obtain the total number of people n1 passing through all entrances and exits on weekdays, and obtain the average working day flow rate Np1=(n1*d1) / 2 of the building blocks on both sides, where d1 is the number of working days counted; Get the total number of people n2 passing through all entrances and exits during holidays, and get the average holiday flow rate Np2=(n2*d2) / 2 of the building area blocks on both sides, where d2 is the number of days of the holidays counted; get the set {Np1, Np2}, then the average daily flow rate Np=Max{Np1, Np2}, where Max{Np1, Np2} is the maximum value in the set.

This is more efficient than traditional manual analysis methods and reduces the possibility of human error. By analyzing the average daily passenger flow, the system can identify high passenger flow areas and give priority to setting up subway stations in these areas. This helps to optimize the urban public transportation network, improve overall traffic efficiency, and reduce congestion. By considering the passenger volume and distance factors of bus stops, those locations that are close to high passenger flow areas and convenient for passengers to reach can be selected as subway stations. This can improve the travel convenience of passengers and increase the utilization rate of public transportation. Since the present invention works based on data analysis, it can be adjusted and optimized according to real-time or regularly updated data. This means that as the city develops and population flows change, the layout of subway stations can be adjusted accordingly to adapt to new traffic needs. A reasonable subway station layout can attract more people and promote commercial activities and economic development in surrounding areas. At the same time, improved traffic conditions can also improve the quality of life of residents and further promote the prosperity of the city. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Figure 1 It is a flow chart of an urban planning management system for building layout of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 As shown, the present invention is an urban planning management system for building layout, comprising: Initial module: obtain all routes in the urban area and obtain a route map; set an initial interval distance, select a number of initial points on the route map according to the initial interval distance, and each adjacent two initial points constitute a correction section; It is understood that all routes within the urban area include streets, avenues, paths, etc., and a comprehensive route map is formed by all routes; the routes are obtained through geographic information system (GIS) data, existing urban planning data or on-site surveys, etc.; after all route information is collected, the information is integrated into a chart to form a detailed route map; As a preferred embodiment of the present invention, the process of setting the initial interval distance includes: Acquire historical site selection data, the historical site selection data including historical site selection points of other urban subway stations; obtain the distance between each adjacent historical site selection point according to the historical site selection data, and obtain the maximum value of all distances, and use the maximum value as the initial interval distance; It is understandable that a reasonable initial spacing distance is determined based on the review and analysis of historical data, thereby providing a reference standard for current urban planning; collecting historical site selection data of subway stations in other cities, the historical site selection data includes location information of subway stations in different cities, that is, subway stations selected in history; after calculating the distances between all adjacent historical site selection points, find the maximum value of these distances, which represents the maximum spacing distance that has appeared in historical site selection; As a preferred embodiment of the present invention, the process of selecting a plurality of initial points on the route map according to the initial interval distance includes: Divide the urban area into grids according to the initial interval distance to obtain a plurality of grid points, and obtain all route intersections on the route map; select the route intersection closest to the grid point at each grid point and record it as an initial point to obtain a plurality of initial points; The process of dividing the urban area into grids according to the initial interval distance is to use the initial interval distance as the distance between adjacent grid points in the grid; It can be understood that the gridding method is used to simplify the complex urban road network, and the initial points are determined by selecting the route intersections closest to the grid points, so as to ensure that these initial points can represent the key traffic nodes in the city; the initial interval distance is used as the distance between adjacent grid points in the grid, and the entire urban area is gridded; the purpose of this step is to simplify the complex urban area into a series of regular grid units, so that the subsequent analysis is more systematic and manageable; after completing the grid division, it is necessary to obtain all the route intersections on the route map; these intersections are where different routes intersect, usually places with large traffic flow and more important; for each grid point in the grid, find the route intersection closest to it; this closest distance is determined by calculating the distance from the grid point to all route intersections, and the selected closest route intersection is recorded as the initial point; Primary analysis module: obtain all the modified road sections in the urban area, and form a closed building area block by a number of modified road sections connected end to end, and obtain a number of building area blocks; obtain the average daily passenger flow Np in the building area blocks on both sides of the modified road section, and obtain the initial point increase according to the average daily passenger flow , where K is the preset location density coefficient, and 0<K<1; It is understandable that the number of initial points that need to be added is estimated by analyzing the average daily passenger flow of the modified section and its surrounding areas; this method can help planners better understand the distribution of passenger flow in different areas of the city, so as to make more reasonable choices in urban planning decisions such as subway station site selection; by using the site density coefficient, the sensitivity of the initial point increase can be adjusted to adapt to different planning needs and actual conditions; It should be noted that several end-to-end modified road sections are combined to form closed building blocks; these blocks represent different building complexes or areas in the city and are the basic units for subsequent analysis; As a preferred embodiment of the present invention, the process of obtaining the average daily flow of people includes: Obtain all entrances and exits in the building blocks on both sides of the corrected road section, obtain the total number of people n1 passing through all entrances and exits on weekdays, and obtain the average working day flow rate Np1=(n1*d1) / 2 of the building blocks on both sides, where d1 is the number of working days counted; Get the total number of people n2 passing through all entrances and exits during holidays, and get the average holiday flow rate of the building area blocks on both sides Np2=(n2*d2) / 2, where d2 is the number of days of the holiday counted; get the set {Np1, Np2}, then the average daily flow rate Np=Max{Np1, Np2}, where Max{Np1, Np2} is the maximum value in the set; It is worth noting that the peak periods of passenger flow at each reference point may be different. Some reference points have peak periods on weekdays, while others have peak periods on holidays. Therefore, the collected passenger flow must meet the peak periods of the reference points to ensure that the subway station can handle the passenger flow during peak hours. Secondary analysis module: according to the initial point increase, the number of reference points of the modified road is obtained, num=z*Aoi, where z is the preset multiple threshold; num reference points are selected at equal intervals on the modified road section, and the bus stop closest to the reference point is obtained, recorded as the nearest bus stop, and the passenger flow index at each reference point is obtained. ,in λ is the preset correction coefficient, L is the distance between the reference point and the nearest bus stop, and L ave is the average distance between each reference point and its nearest bus stop, pf is the number of passengers at the nearest bus stop of the reference point, and pf ave is the average passenger volume of the nearest bus stop at each reference point; It can be understood that by analyzing the reference points on the modified section and the bus stops nearby, the traffic flow and the layout of public transportation services can be evaluated and optimized; the calculation of the passenger flow index takes into account the two factors of distance and passenger volume, aiming to provide a comprehensive indicator to evaluate the convenience and attractiveness of transportation near the reference point; by using the correction coefficient and the average value, this method can adapt to different situations and provide a relatively objective evaluation standard; It should be noted that the location of subway stations can be based on bus stops as a reference, and the closer the location of subway stations is to bus stops, the more convenient it is for citizens to transfer; As a preferred embodiment of the present invention, the process of setting the multiple threshold includes: Set the minimum distance d between subway stations min , obtain the length R of the modified section, and then obtain the maximum number of reference points num max =(R / d min )-1, then the setting range of the multiple threshold is [1, num max / Aoi] and z∈Z, where Z is a set of positive integers; It can be understood that by setting a reasonable multiple threshold range, the number of reference points can be controlled to optimize traffic flow analysis and station layout; this method ensures that the distribution of reference points is neither too sparse nor too dense, which helps to improve the accuracy and efficiency of data analysis; at the same time, by considering the minimum distance between subway stations, the convenience and comfort of passengers are guaranteed; the setting range of the multiple threshold means that the multiple threshold can start from 1, up to the ratio of the maximum number of reference points to the increase in the initial points (rounded down); As a preferred embodiment of the present invention, the reference point is selected by giving priority to the route intersection, and does not include the initial points at both ends of the modified section; It should be noted that when selecting reference points, priority is given to locations located at route intersections; route intersections are usually the intersections of multiple roads or paths, which often have higher traffic volumes and more complex traffic conditions, and therefore can provide richer data and analysis value as reference points; As a preferred embodiment of the present invention, the process of obtaining the passenger volume of the nearest bus stop includes: Get the number of passengers on weekdays at the nearest bus stop Pv1=(p up +p down ) / d1, where p up is the total number of people boarding the bus at the nearest bus stop on weekdays, p down The total number of people getting off at the nearest bus stop on weekdays; Get the holiday passenger volume Pv2 of the nearest bus stop during holidays = (p up ´+p down ´) / d2, where p up ' is the total number of people boarding the bus at the nearest bus stop during holidays, p down ´ is the total number of people getting off at the nearest bus stop during holidays; a new set {Pv1, Pv2} is obtained, then the passenger volume pf = Max{Pv1, Pv2}, where Max{Pv1, Pv2} is the maximum value in the new set; It is understandable that by considering the passenger volume on weekdays and holidays, the passenger demand at the bus station can be more accurately assessed; this method can balance the differences in passenger flow on different days and ensure that the passenger volume estimation is more comprehensive and accurate; by selecting the maximum of the two, it can ensure that the highest passenger demand can be met on any given day; Site selection module: Arrange the passenger flow index of each reference point from large to small, select the reference points corresponding to the first Aoi passenger flow indexes, and record them as the best reference points; obtain all the site selection points of the modified section according to the initial points and the best reference points at both ends of the modified section, and obtain all the site selection points in the urban area from the site selection points of each modified section; It can be understood that the passenger flow index is based on multiple factors, such as passenger flow, station spacing, passenger demand, etc., and is used to evaluate the traffic attractiveness or importance of a location; the initial points at both ends of the correction section and the above-selected optimal reference points are used to determine all the site selection points of the entire correction section, which are the specific locations where subway stations are recommended to be set up; finally, the site selection points of each correction section are integrated to form all the site selection points in the entire urban area, which helps urban planners and traffic engineers to optimize the site layout throughout the city.

[0019] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
