Exploratory analysis of urban mobility: From mobile phone usage data to tourist behaviour

In this paper, we propose to use tools of exploratory spatial analysis to study the mobility of foreign visitors in a city like Paris. Using digital traces from mobile phones, we explore several aspects of mobility: how people move from one place to another, but also how these places are linked together. The exploration depends on a methodology which uses visualizations to reveal patterns in large heterogeneous data-sets.. This allowed us to gain new insights on how to analyze noisy and imprecise spatio-temporal data, and to formulate a reliable hypothetical model of tourist urban mobility.
