Embodiment Construction

[0044] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0045] The separation method of the vehicle running track of the present embodiment comprises the following steps:

[0046] (1) Obtain the satellite positioning data of the vehicle running within the set time period, each satellite positioning data includes the acquisition time corresponding to the satellite positioning data, vehicle position and passenger loading status;

[0047] (2) Screen the acquired satellite positioning data according to the passenger loading state of each satellite positioning data, and form a corresponding passenger-carrying trajectory according to the screening results;

[0048] (3) Determine the time jump point and the space jump point of the passenger trajectory,

[0049] And according to the position of the time jump point and the space jump point, the passenger trajectory is divided into several sub-trajectories: the division ...

Abstract

The invention provides a method for separating a vehicle running track, and includes the steps of: (1) acquiring satellite positioning data of operation of a vehicle in a set period of time, the satellite positioning data including the acquisition time, the vehicle position and the passenger carrying state corresponding to the satellite positioning data; (2) screening the acquired satellite positioning data according to the passenger carrying sate of each satellite positioning data and forming a corresponding passenger carrying running track according to a screening result; and (3) determining the positions of time jump points and space jump points of the passenger carrying running track, and dividing the passenger carrying track into a plurality of sub-running tracks according to the positions of the time jump points and the space jump points. The method for separating the vehicle running track completes division in sequence according to the time jump points and the space jump points, is easy to realize, and fully considers the characteristic of the vehicle running track, thereby enabling a finally obtained track separation result to be more accurate, and accuracy of a result of performing motion mode mining using the track separation result can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method for separating vehicle running trajectories. Background technique [0002] Today, in the face of the development trend of global informationization, traditional transportation technologies and means no longer meet the requirements of economic and social development. Intelligent transportation system is an inevitable choice for the development of transportation. Intelligent transportation develops with the continuous development of sensor technology, communication technology, GIS technology (geographic information system), 3S technology (remote sensing technology, geographic information system, global positioning system) and computer technology. [0003] In recent years, with the maturity and popularity of satellite positioning technology, the current means of transportation, including vehicles, are basically equipped with satellite positioning equipme...
