Problems solved by technology

However, only the number of people within the sensing range of the instrument can be collected, and the population distribution of all areas within the entire city cannot be obtained, nor can the population travel trajectory information be continuously extracted, and the population migration and distribution rules within the entire city cannot be obtained.

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the examples.

[0028] like figure 1 As shown, a kind of dynamic population distribution density detection method based on mobile phone positioning data provided by the present invention, its steps are:

[0029] Step 1, according to the actual analysis needs of the target city, determine the (Traffic Analysis Zone, Traffic Analysis District) division scheme of the target city analysis area range TAZ, divide the analysis area range TAZ into N analysis sub-region ranges TAZ(i), i is a natural number from 1 to N. For the principle of TAZ division of the analysis area, refer to the Chinese patent application number 201110033833.4.

[0030] Each analysis sub-area TAZ(i) can be divided into two types: internal analysis sub-area TAZ(i) and boundary analysis sub-area TAZ(i) according to whether there is a channel leaving the entire analysis area. The internal analysis sub-area TAZ(i) means that there...

Abstract

The invention provides a dynamic population distribution density detecting method based on mobile phone positioning data, which is characterized by including the steps: dividing an analysis area coverage, needing population distribution density analysis, of a target city into different subareas, subsequently, establishing a virtual sensor network, obtaining the mapping relation between each subarea and the virtual sensor network, and obtaining a sum of the population in each subarea according to mobile phone signals. The dynamic population distribution density detecting method based on the mobile phone positioning data has the advantage that dynamic population distribution density detection is realized by fully depending on existing mobile communication network resources, utilizing mass mobile phone signal data as input and employing a distinguishing mechanism based on traveling track continuous tracking and stay duration time in the area. The method can be used for automatically detecting population distribution density information at a high frequency.

Description

technical field [0001] The invention relates to a dynamic population distribution density detection method based on mobile phone positioning data, which is used to mine valuable dynamic urban population spatial distribution density information from massive mobile phone user data, which can be used for traffic planning, traffic demand management, traffic The policy evaluation and traffic operation management services belong to the technical field of traffic planning and management methods. Background technique [0002] Cities are the concentration of population, capital and technology. As human settlements, the development of cities is closely related to the density of population distribution. The spatial distribution of urban population is one of the most important factors affecting social and economic development, infrastructure construction, public service allocation, and urban industry, housing, transportation, environment, etc. It is the basis for scientific urban planni...
