Urban agglomeration comprehensive city flow measurement method and system based on big data

Abstract

The invention discloses an urban agglomeration comprehensive city flow measurement method and system based on big data, and the method comprises the following steps: firstly, obtaining city flow data through a web crawler and other means based on a big data technology; secondly, processing the urban flow data by adopting a normalization method to obtain dimensionless data; then, using an analytic hierarchy process supported by an entropy technology to determine the weight of each city flow; and finally, measuring the intensity index of the comprehensive urban flow in the urban agglomeration area. According to the invention, the basic data used for measuring the urban flow of the urban agglomeration area can be rapidly extracted from the network big data, the respective weight is determined, and the comprehensive urban flow intensity is measured and calculated. According to the method and the device, the problems that a large amount of cost needs to be consumed for obtaining basic data in urban agglomeration area space connection strength measurement and timeliness lag exists in the obtained basic data in the prior art are solved, dynamic measurement of the urban agglomeration area space connection strength is realized, the timeliness is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a method for measuring and calculating urban flow, in particular to a method and system for measuring and calculating comprehensive urban flow of urban agglomerations based on big data. Background technique [0002] At present, with the gradual improvement of the urbanization level and the continuous improvement of infrastructure in urban agglomerations, the exchanges between cities are becoming increasingly close. Urban agglomerations are no longer just a group of cities that gather in space. Personnel exchanges, material exchanges, economic interactions, and information exchanges are carried out through means of flow and information flow, gradually forming a complex urban system of dynamic cooperation. Domestic academic circles have also carried out extensive research on urban linkages. The research contents mainly include the impact of changes in urban linkages on regional spatial structure, changes in the direction and stre...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing research focuses on national and provincial macro-scales, and lacks research on urban agglomerations

[0005] 2. The existing research focuses on a single city and analyzes its economic relationship with surrounding cities, which belongs to a one-to-many relationship, and lacks research on the interconnection between cities, that is, the many-to-many relationship

[0006] 3. The existing research mainly focuses on a certain aspect of inter-city research, such as the research on logistics, which has a single dimension and the research conclusions are one-sided
