Travel purpose identification method and device based on mobile phone signaling data

Abstract

The invention relates to the technical field of travel purpose identification, in particular to a travel purpose identification method and device based on mobile phone signaling data. The travel purpose identification method comprises the following steps: extracting OD data, and dividing population types and occupational and residential places; obtaining and associating POI and base station positions with the located blocks respectively to form a position corresponding relation; preliminarily identifying the travel purpose based on the corresponding relationship between the location block of the travel destination base station and the POI type and the occupational and residential place corresponding to the plot, extracting characteristic parameters, clustering the remaining samples based on a K-means clustering algorithm, and finally obtaining the travel purpose; and correcting the travel destination result according to the population type. According to the embodiment, based on the mobile phone signaling data and the POI points, resident travel purposes are divided through a machine learning algorithm, and meanwhile, the result is corrected in combination with travel behavior characteristics of crowds, so that dependence and requirements on priori experience knowledge are reduced, and subjectivity brought by a single rule discrimination method can be avoided.

Description

technical field [0001] The present invention relates to the technical field of travel purpose recognition, in particular, to a method and device for travel purpose recognition based on mobile phone signaling 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. As a portable communication device, mobile phones have been rapidly popularized among the people with the development of the economy. As of 2016, the number of mobile phones in my country has exceeded 96 per 100 people. Everyone in the Shang Dynasty has a mobile phone. In order to meet the needs of users for communication and Internet access, the mobile terminal will establish contact with the adjacent cellular base station, and record the time when the user accesses the base station and the location information of the base station. It can t...

Problems solved by technology

On the other hand, most of the existing studies are only based on the POI characteristics of travel endpoints when identifying travel purposes. However, as urban land use becomes more and more complex and residents travel more and more diversified, it is difficult to identify travel purposes based on POI alone. for accurate identification
