Example Embodiment

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] The spatiotemporal pattern mining method of the movement trajectory generation model of multi-source data fusion provided by the present invention will be described in detail below.

[0037] 1. Data requirements

[0038] Since the movement trajectory data is actually a time series of position data (latitude and longitude), in addition to the movement trajectory data, the other data involved in the present invention includes at least t...

Abstract

The invention discloses a spatio-temporal pattern mining method of a mobile trajectory generation model based on multi-source data fusion. This method introduces multi-source data into mobile trajectory data mining, constructs a mobile trajectory generation model based on probability graph model, and with time-space constraints, mining of spatio-temporal patterns of urban trajectory data under multi-source data is conducted. The method greatly reduces man-defined factors and has strong generalization.

Description

technical field [0001] The invention relates to the technical fields of data mining and smart cities, and more specifically relates to a spatio-temporal pattern mining method of a moving trajectory generation model fused with multi-source data. Background technique [0002] Mobile trajectory pattern mining is currently a research hotspot in the intersection of data mining and smart cities. It uses the movement trajectory data generated in the city, such as cars, people, bicycles, etc. to mine traffic-related patterns existing in urban roads or areas. Its research content involves urban planning, urban functional zoning, traffic mode research, etc. [0003] The research object of the existing urban mobility trajectory pattern mining technology is mostly a kind of trajectory data, such as taxi trajectory data, mobile phone data and bicycle data. Most of these data mining techniques do not involve the fusion of multi-source data, and the patterns they discover can only reflec...
