Abstract

It is now possible to record and collect a large amount of phone calls in a 
city. Each phone call record usually contains the caller and callee IDs, date 
and time, and the base station where the phone calls are made. As mobile phones 
are widely used in our daily life, many human behaviors can be revealed by 
analyzing mobile phone data. In this paper, we propose a comprehensive visual 
analysis system which can be used to analyze population’s mobility pattern from 
millions of phone call records.

Our system consists of three major components: 1) visual analysis of user 
groups in a base station; 2) visual analysis of the mobility pattern of 
different user groups making phone calls in certain base stations; 3) visual 
analysis of handoff phone call records. Some well established visualization 
techniques such as parallel coordinates and pixel-based representations have 
been integrated into our system. We also develop some novel visualization 
schemes such as Voronoi-diagram-based visual encoding to reveal the unique 
features of mobile phone data.

We have applied our system to the real mobile phone data collected in a large 
city and some interesting findings regarding people’s mobility pattern have 
been obtained.
