Problems solved by technology

This method ignores the diversity of crowd activities in public spaces, and only focuses on the scale of activities. The measurement results are too single for the representation of vitality connotation, and the measurement results will have large deviations.

Abstract

The invention discloses a public space vitality measurement method and system based on trajectory positioning data. A method of combining spatial statistics and complex network analysis is adopted; massive crowd trajectory positioning data are cleaned and aggregated; the spatial stroll data set is automatically extracted and constructed, and then the integration of the revisit rate, the activity mixing degree and the network centrality is adopted as the measurement index of the public space vitality, so that the defects of the existing evaluation system are overcome, the deviation caused by directly measuring the vitality by using the scale density is avoided, and meanwhile, the real-time measurement can be realized.

Description

technical field [0001] The present invention relates to a space vitality measurement technology, in particular to a measurement method and system for measuring public space vitality (tourist revisit, activity type, and spatial connection) based on massive microscopic individual trajectory data. Background technique [0002] The methods currently used to measure the vitality of public space mainly include the following: [0003] (1) Measurement based on the quality of physical space environment: Using the method of combining qualitative description and quantitative analysis, the location characteristics, traffic accessibility, and functional diversity of public space at the macro scale; the operation and maintenance of space facilities and environmental cleanliness at the micro scale Degree, visual design aesthetics (such as: landscape sketches, waterfront, etc.) evaluation to carry out vitality measurement. Ignore the subject of spatial vitality --- the space-time dynamics ...
