Croissance urbaine et accessibilité : intérêts et limites de l’approche par les densités dans une perspective de modélisation de l’usage du sol

Land-Use and transport interaction models today take an important role as decision-making tools, especially in a context marked by the reinforcement of economical, energy and environmental constraints. If the estimation of transport demand and accessibilities in these models depends on densities, th...

description	Land-Use and transport interaction models today take an important role as decision-making tools, especially in a context marked by the reinforcement of economical, energy and environmental constraints. If the estimation of transport demand and accessibilities in these models depends on densities, these densities are often viewed as exogenous. This paper intends to render them endogenous by measuring the effect of accessibilities on intra-urban densities in the urban area of Lyon in 1990, 1999 and 2006, and defining an evolution law over time for the coefficients of the model.
