The UrbanSim model is a model dedicated to urban simulation. It has been
developed and enhanced during the last fifteen years ([WAD 02]), with a clear
operational objective. The model is used as a tool in decision support for testing the
effects of urban policies in transport (individual and collective), spatial planning and
environmental policies. This model is initially based on a coupling between a
microsimulation model and a geographical information system (GIS) that allows to
manage and represent the different layers of information at stake (environment,
transport, land use) at the same time. The model has been applied to many cities and
several other methodological couplings have been progressively introduced. The
microsimulation model manages the individual choices in terms of demography
(giving birth for example) and jobs. Discrete choice statistical models are used to
estimate the localizations of households and jobs. A CA model is used to predict the
changes in land use, whose principles are based on neighborhood effects. A MAS is
