Urban systems are composed by complex couplings of several components, and\nmore particularly between the built environment and transportation networks.\nTheir interaction is involved in the emergence of the urban form. We propose in\nthis chapter to introduce an approach to urban morphology grasping both aspects\nand their interaction. We first define complementary measures, study their\nempirical values and their spatial correlations on European territorial\nsystems. The behavior of indicators and correlations suggest underlying\nnon-stationary and multi-scalar processes. We then introduce a generative model\nof urban growth at a mesoscopic scale. Given a fixed exogenous growth rate,\npopulation is distributed following a preferential attachment depending on a\npotential controlled by the local urban form (density, distance to network) and\nnetwork measures (centralities and generalized accessibilities), and then\ndiffused in space to capture urban sprawl. Network growth is included through a\nmulti-modeling paradigm: implemented heuristics include biological network\ngeneration and gravity potential breakdown. The model is calibrated both at the\nfirst (measures) and second (correlations) order, the later capturing\nindirectly relations between networks and territories.\n
