DESCRIPTION:Human mobility and social interactions have always been subjec
 ts of interest to many disciplines\, including sociology\, geography\, and
  economics. These topics are key to address real-life problems like the de
 sign optimal transportation systems for goods and individuals\, the contro
 l and prevention of epidemic spreading\, and the forecast of social and ec
 onomic consequences of migrations. Today\, thanks to the availability of l
 arge and detailed datasets on people's communications and whereabouts\, we
  are in the position to test the validity of classical theories and models
 \, improve them\, and develop a deeper understanding of the underlying mec
 hanisms governing our society.\nIn this talk we introduce a decision-based
  stochastic model to estimate commuting flows\, the radiation model\, and 
 discuss its connection with other spatial interaction models. We present s
 ome generalisations of the model\, and analyse two scenarios in which we t
 ested the model's performance using GSM and GPS data. Finally\, we discuss
  the contribution of spatial interaction models towards the understanding 
 of the urbanisation process.
