Problems solved by technology

The density-based method is mainly to remove "noise", and then obtain aggregations with higher density in a certain area in the space, which will remove more user positioning data, making the clustering results unreliable
Grid-based methods are poor at dealing with irregularly distributed data, so they are not suitable for analyzing user location data that is not very regular

Embodiment Construction

[0046] A method for calculating personal commuting distance based on mobile terminal GPS positioning data records proposed by the present invention is described in detail as follows in conjunction with the accompanying drawings and embodiments.

[0047] The method of the present invention is mainly based on the following principles: most people have relatively fixed working locations and working hours, and relatively regular commuting methods and routes. Therefore, after collecting the GPS positioning data records of the user at different time points through software collection, etc., it is possible to first analyze the geographic location of the user's home and work place, and then analyze the GPS positioning data between the user's home and work place. Data records, you can get the trajectory of the user's commute. By analyzing the obtained commuting trajectory, the accurate distance of the user's personal commuting can be calculated. The method of the invention has no spec...

Abstract

The invention discloses a method for recording a personal commuting distance based on GPS positioning data of a mobile terminal, belonging to the technical field of computer application. The method comprises the following steps: firstly, carrying out data collection so as to collect a GPS positioning data record produced by a certain mobile terminal of a user in a certain period of time; calculating a central point of the GPS positioning data record, and establishing a central point record set; clustering central point records, calculating a commuting key point, and determining geographic positions of a house and workplace of the user; and finally, calculating to obtain a commuting track and commuting distance of the user each day and an average commuting distance of the user in a period of time. According to the method, the personal commuting distance of the user is calculated by virtue of the widely-collected GPS positioning data records of the user and can be still accurately calculated when the GPS positioning data records collected in a short term are few.

Description

technical field [0001] The invention belongs to the field of computer application technology, in particular to a method for calculating personal commuting distance based on mobile terminal GPS positioning data records. Background technique [0002] Commuting is the travel behavior of urban residents due to the separation of work and residence. Commuting is one of the most basic and important travel behaviors of urban residents. It has an important impact on a person's life and work, and also affects a city's economy. and social development. In recent years, with the continuous expansion and development of the city, the separation of residents' jobs and residences has intensified, the commuting situation has become increasingly complex, and the problem of prolonged travel time has begun to emerge. Especially, traffic congestion during morning and evening peak commuting hours has become the most prominent problem in urban traffic. one of the problems. Improving residents' co...
