Life circle recognition method based on positioning data

Abstract

The invention discloses a life circle recognition method based on positioning data. The method comprises the following steps: firstly, preprocessing a positioning data file; performing behavior pointrecognition on the positioning data, and dividing living behavior points, working behavior points and a living behavior point set according to the duration of the behavior points in a specific time period; selecting a specific city or area, actually measuring or assigning an empirical value, and obtaining a life circle radius D value; extracting living behavior points with the distance from the living behavior point M and the working behavior point N smaller than D values, and forming a living behavior point set Q and a working and living behavior point set S; and respectively extracting the point M and the point set Q and the point N and the point set S to form a minimum boundary geometric surface area, and forming a living circle surface area and a working circle surface area. Accordingto the method, positioning data are fully utilized, the real residence or work life circle of the crowd is accurately delimited, the method is more scientific and objective compared with a traditionalcircle layer delimiting method with the living place as the circle center, and a scientific basis is provided for analysis and construction of living or work life circle planning.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and in particular relates to a living circle identification method based on positioning data. Background technique [0002] With the continuous upsurge of urban renewal, people's demand for intensive spatial layout and exquisite quality of life continues to increase. As the basic unit of urban human settlements, the living circle determines the spatial configuration of urban facilities and the shaping of the quality of life. The existing methods of defining the scope of the living circle at home and abroad mainly define the living circle by time distance, space distance or function. [0003] Among the methods of defining the scope of this kind of living circle, the analysis method of defining the living circle by time distance mainly delineates the boundary of the urban living circle by calculating "15-minute walking distance" and "one-hour commuting circle"; The living circle mainly det...

Problems solved by technology

[0005] Purpose of the invention: In view of the above problems, the present invention proposes a method for identifying living circles based on positioning data, aiming at the problem that existing living circles are simply circled by the place of residence or work, ignoring the real situation of the crowd, and identifying the crowd with positioning data Behaviors within the daily walking range are integrated to obtain the real living and working circles of the crowd
