Embodiment Construction

[0058] The method for calculating personal commuting time based on the GPS positioning data of the mobile terminal proposed by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] Due to the randomness of users using mobile terminal positioning services, the positioning coordinate points generated by users during commuting are often relatively sparse, which brings challenges to accurately calculate the commuting time of users. 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. By aggregated analysis of similar commuting trajectories of users, a relatively accurate commuting trajectory of the user can be obtained. Using the trajectory as a reference, the accurate commuting rate of the user can be analyzed, and the commuting time of the user can ...

Abstract

The invention provides a method for calculating commuting time of an individual on the basis of GPS positioning data of a mobile terminal, belonging to the technical field of computer application. Themethod includes the following steps: calculating commuting tracks of users within a period of time and initializing a commuting track cluster set, and finding out two commuting track clusters which are shortest between each other in distance in the commuting track cluster set if the number of commuting track clusters is greater than one; if the distance between the two clusters is less than or equal to the maximum distance threshold, combining cluster commuting tracks corresponding to the two commuting track clusters in space and time, and then combining the two commuting track clusters; andif the number of the commuting track clusters cannot be reduced, ending clustering and obtaining commuting time corresponding to each commuting track through calculation. The commuting time of each user can be accurately calculated by conducting clustering on similar commuting tracks of the users, so the method has great application values for improving urban traffic conditions.

Description

technical field [0001] The invention belongs to the field of computer application technology, in particular to a method for calculating personal commuting time based on GPS positioning data of a mobile terminal. Background technique [0002] With the rapid development of the city, the separation of jobs and residences is intensifying, the commuting situation of urban residents is becoming more and more complicated, and the problem of prolonged travel time has begun to emerge, especially the traffic congestion during morning and evening peak hours has become one of the most prominent problems in urban traffic. one. Improving the commuting conditions of urban residents and shortening commuting time has become an inevitable requirement for promoting the improvement of urban living environment and the sustainable development of urban transportation. However, due to the limitations of economic and space conditions, the method of simply relying on increasing investment in large-s...
