Problems solved by technology

This scheme is limited to matching different types of check-in data of the same user with time-space correlation, and because the travel data of the resident survey is obtained by manual filling, there are errors in time and space latitude

Embodiment Construction

[0042] Resident travel survey data includes residents' gender, age, departure traffic area number, arrival traffic area number, departure time, and arrival time of each travel record. The travel base station trajectory information extracted from the mobile phone signaling data also includes the departure point and arrival point of each travel trajectory (the recording unit is the base station), the trajectory departure time and arrival time, and the gender and age of the user corresponding to the IMSI number . Through the correspondence of these characteristic attributes, the travel trajectory extracted from the mobile phone signaling data can be matched with the resident travel survey data. When the two records are successfully matched under the set rules, the travel mode of the mobile phone signaling travel trajectory can be obtained. , travel purpose and other personal travel information and family attribute information, so as to obtain mobile phone trajectory sample data i...

Abstract

The invention discloses a method for obtaining mobile phone signaling track data with a label based on resident survey data. The method comprises the following steps: S1, obtaining basic attribute information of the mobile phone signaling track data and resident travel survey data; S2, converting the mobile phone travel OD into a traffic cell travel OD based on the spatial correspondence between the mobile phone base station and the traffic cell; S3, extracting feature sets of mobile phone signaling trajectory data and resident travel survey data for different dates, and performing preliminaryfusion on the data in time latitude; S4, based on the travel characteristic attribute of each part of resident travel survey data, performing preliminary screening matching on the mobile phone signaling track data under the set matching rule; and S5, in combination with the personal characteristic attributes of the traveler and the mobile phone user, completing final characteristic matching of the resident travel survey data and the mobile phone signaling track data, and obtaining the mobile phone signaling track data with the label. Data fusion of a mobile phone signaling data large sample and a resident travel survey data small sample is realized.

Description

technical field [0001] The invention relates to the field of big data and small data matching, in particular to a method for acquiring tagged mobile phone signaling track data. Background technique [0002] With the development and popularization of communication and Internet technology, the mining research of big data with a large amount of potential information behind it emerges as the times require. According to statistics from the Ministry of Industry and Information Technology, by the end of 2015, there were 1.286 billion mobile phone users across the country, and the penetration rate of mobile phones was 94.5 per 100 people. Its mobile phone signaling data has attracted the attention of many scholars due to its rich content, high sampling rate and good timeliness. However, due to the protection of privacy and some limitations of the data collection field, it is difficult to obtain accurate sample information with labels, such as the types and attributes of travelers a...
