Embodiment Construction

[0030] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail. It should be noted that this application is applicable to sample sampling in different application scenarios. In order to better explain the technical solution of the application, the application takes the sample survey of residents' travel as an example to explain the technical solution of the application. Sample sampling methods for other scenarios can be obtained by analogy to the ...

Abstract

This application is applicable to the technical field of data processing, and provides a method and device for travel survey sampling. The method includes: obtaining the characteristic data of each area under different area levels; A feature data, obtain the first joint distribution value of the first area; according to the first joint distribution value, extract the first sampling sample set corresponding to the first area in the first sample set; use the first sampling sample set as the second The total sample set corresponding to the second area of ​​the area level, based on the second characteristic data corresponding to the second area, obtains the second joint distribution value corresponding to the second area; according to the second joint distribution value, extracts from the first sampling sample set The second sampling sample set corresponding to the second region. Compared with the traditional sampling method, since this application adopts region-based stratified sampling, it avoids the disadvantages of sampling caused by a single reference condition and improves the representativeness of the sampling sample.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a method and device for travel survey sampling. Background technique [0002] The basic requirement of sampling is to ensure that the selected sample units are fully representative of all samples. The purpose of sampling is to estimate and infer all sample characteristics from the analysis and research results of the sampled units, so as to effectively improve the quality of subsequent data analysis, parameter estimation and modeling. [0003] However, traditional sampling methods often use a single reference condition for sampling processing, resulting in unrepresentative sampling samples. For example, in the sample survey of residents' travel, due to the influence of multiple factors such as the unbalanced regional development and the differences in residents' travel behavior, it is impossible to obtain a representative sample.
