Problems solved by technology

[0003] Due to the diversity of travel patterns of mobile phone users and the fact that satellite positioning technology will be affected by environmental factors in practical applications, it is difficult to judge mobile phone users without accurately obtaining their car ownership conditions.

Embodiment 1

[0030] see figure 1 , in an embodiment of the present invention, a method for judging a mobile phone user's car ownership situation includes the following steps:

[0031] Step A, obtain satellite positioning trajectory data and accelerometer data:

[0032] Specifically, start the satellite positioning module (including the interior of the driving vehicle, on-board smart devices, smart phones, etc.), establish a data connection with the computing terminal through the satellite positioning module, and obtain the satellite positioning latitude, satellite positioning longitude, satellite positioning time, and satellite positioning direction , satellite positioning speed, satellite positioning accuracy, satellite number and other travel data, and at the same time obtain the accelerometer X-axis acceleration, Y-axis acceleration and Z-axis acceleration through the accelerometer module.

[0033] Step B, perform data outlier detection filtering and preprocessing:

Embodiment 2

[0046] see Figure 1-3 , the difference between this embodiment and embodiment 1 is:

[0047] In this embodiment, step D in embodiment 1 specifically includes the following steps:

[0048] 1) Divide the turn time segment of the itinerary: when the sum of the satellite positioning azimuth angles is greater than a certain angle, it is used as the user's turn data, and all the turn time segments are extracted;

[0049] 2) Feature discovery: Through the analysis of all satellite positioning time segment data, the user's speed, acceleration, and turning can be well described to describe his driving characteristics;

[0050] 3) Variable selection: Through the correlation analysis of the user's itinerary characteristics, the correlation is displayed with the correlation coefficient matrix heat map. It is found that the color is relatively dark, that is, the correlation is weak, so the selected variables are representative. The selected variables are: average speed, maximum speed, m...

Abstract

The invention relates to the field of mobile phone user attribute judgment, in particular to a method for judging a mobile phone user's car ownership, comprising the following steps: acquiring satellite positioning trajectory data and accelerometer data; performing data abnormal point detection, filtering and preprocessing; supplementing bus stops Geographic information; feature extraction and selection; identification of buses and other modes of transportation; identification of whether a user has a car. The present invention uses satellite trajectory data, accelerometer data, and bus station geographical information to accurately and reasonably judge whether the user has a car after identifying the bus and other traffic patterns, that is, without investigating the actual car ownership situation of the user. Under the circumstances, it is possible to determine the car ownership status based on the itinerary data provided by the user, which reduces the cost of information collection and avoids infringing on the user's personal privacy and other legal rights.

Description

technical field [0001] The invention relates to the field of judging attributes of mobile phone users, in particular to a method for judging the car ownership situation of mobile phone users. Background technique [0002] In today's society, traveling by private car has become one of the important ways for people to travel. With the popularity of in-vehicle smart devices and smartphones, it is becoming more and more convenient to obtain travel data of mobile phone users. With the improvement of big data storage capacity and computing power, it is imperative to apply mobile phone user travel data to insurance analysis and government traffic supervision. The identification of whether a mobile phone user owns a car will provide strong support for the analysis, judgment and prediction of his driving behavior. [0003] Due to the diversity of travel patterns of mobile phone users and the fact that satellite positioning technology will be affected by environmental factors in pra...
