Title:
POPULATION DISTRIBUTION AGGREGATION CALCULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/095480
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a population distribution aggregation calculation device capable of calculating a highly accurate population distribution. This population distribution aggregation calculation device is provided with: a micro-region mesh group management unit 108 which uses approximate location information about user terminals 200 to acquire the number of user terminals located in each predefined macro-region mesh and thereby generate macro-region mesh data, and which also uses detailed location information stored in a positioning data storage unit 102 to acquire, for each prescribed location information acquisition pattern, the number of user terminals located in each of a plurality of micro-region meshes that are obtained by dividing the macro-region meshes by a prescribed geographical resolution, and thereby to generate micro-region mesh data; a reliability level evaluation unit 109 which calculates the reliability level of the micro-region mesh data for each location information acquisition pattern on the basis of the micro-region mesh data and the macro-region mesh data; and a population distribution estimation unit 110 which, in accordance with the reliability level, estimates the number of terminals in each micro-region mesh on the basis of the micro-region mesh data and the macro-region mesh data.
