Problems solved by technology

[0003] At present, there is no sample expansion method for freight travel data. Since the data involved in freight management is very different from the resident travel survey and the distribution of vehicle ownership, it is difficult to deal with it according to the sample expansion method of these two aspects. It is necessary to design a new method of expanding sample calibration

Abstract

An embodiment of the present invention provides a sample expansion check method based on shared platform freight travel data, which relates to the technical field of freight management statistics. The sample expansion check method combines the shared platform freight travel data to perform targeted extraction of freight data, and The original data is cleaned, corrected and perfected. On this basis, the sample expansion study of the freight survey is completed, and the macro scalar is used to cross-check the sample expansion data to determine the sample expansion error and minimize the freight expansion sample results. The deviation from the actual freight survey, the scientific and reasonable results of freight expansion samples, and the accurate presentation of the characteristics of freight travel.

Description

technical field [0001] The invention relates to the technical field of freight management statistics, in particular to a method for expanding samples and checking based on shared platform freight travel data. Background technique [0002] In the prior art, in terms of the survey of residents' trips and the distribution of vehicle ownership, there is a corresponding method of expanding the sample to check. The data involved include household survey data, such as family information, personal information and personal travel information, and outdoor survey data, such as road flow and passenger load rate survey data, bus passenger flow survey data and rail passenger flow survey data. Most require manual collection. [0003] At present, there is no sample expansion method for freight travel data. Since the data involved in freight management is very different from the resident travel survey and the distribution of vehicle ownership, it is difficult to deal with it according to th...
