Modeling the evolution of cities — •Marc Barthelemy — IPhT/CEA, Saclay, France — CAMS/EHESS, Paris, France

The recent availability of data about cities and urban systems opens the exciting possibility of a `new Science of Cities'. Urban morphogenesis, activity and residence location choice, mobility, urban sprawl and the evolution of urban networks are just a few of the important processes that can be discussed now from a quantitative point of view. In this talk, I will discuss how a data-informed approached can elaborate on urban economics models in order to get predictions in agreement with empirical observations. I will illustrate this approach on the growth of cities and the emergence of a polycentric structure of activity centers. I will conclude by highlighting some important challenges and possible research directions.
