Benefits of technology

This patented technology allows us to divide spaces based on their impacts from humans without changing any programming or relying solely on physical boundaries like streets. It also includes methods such as region dividing strategies and optimal placement techniques. Overall, it offers an improved way to manage resources within specific locations while maintaining good communication between people who may have similar goals at home or work.

Problems solved by technology

Technological Problem addressed in this patents relates to improving Zoned Region Division Planning (ZSP), specifically how to efficiently divide spaces within specific domains while maintaining their structural integrity during zonal analysis. Existing solutions either require manual intervention or involve complex mathematical calculations, making it challenging even if some were possible.

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] For the original check-in data, the preprocessing of coordinate correction and data filtering is carried out first. The current check-in data is geo-referenced to GCJ-02, which systematically offsets its coordinates from where it would be in real space. Therefore, the coordinate correction here is to convert the GCJ-02 coordinate system to the WGS84 coordinate system, so that the check-in data can be consistent with other geographic data. Invalid data includes missing information (including missing coordinates, check-in time, and user ID) and invalid information (referring to the check-in location being outside the TAZ boundary). Data filtering is used to identify these invalid data and simply remove them. At the same time, the filtered check-in records are used to construct the check-in track in chronological order by the check-in users.

Abstract

The invention provides a human activity network area division method with space constraints, which belongs to the application field of smart city planning. Furthermore, a clear spatial constraint is added to the topology of the interactive network, and a network area division method with spatial constraints is designed. This method outperforms the regional division method that only uses spatial clustering. It can well extract the areas formed under the influence of human interaction behavior, compare the relationship between human interaction areas and urban administrative divisions, and can provide decision support for urban planning and other fields. .
