  The aim of this paper is to present a model of interaction between transport
and land use which aims at endogenously integrates the provision of
transportation infrastructure and its effects on land use, with a long term
perspective (Lowry, 1964, Wegener, 2004, Levinson, 2011, Bretagnolle, 2014,
Mimeur et al., 2015). LUTECIA (Land Use, Transport, Evaluation of Cooperation,
Infrastructure provision and Agglomeration effects) model puts emphasis on
multiscale processes of urban growth, in the context of the emergence of
Mega-City Regions (MCR, Hall & Pain, 2006). It allows us, in this exploratory
phase, to characterize via simulation the conditions of development of
polycentric metropolises. Nevertheless, we argue that such approaches are all
the more necessary that we are in a period of multiple transitions that
classical modelling tools have difficulty to capture.
