Representação do fenômeno urbano por meio de modelos integrados dos transportes e uso do solo: revisão da literatura e discussão conceitual

Abstract

This paper’s main objective is to evaluate the capability of integrated land-use transport (LUTI) operational models to represent the urban phenomenon, as an initial step towards expanding the role of modeling in the urban planning process. Currently, the application of these tools is focused only on the final stage of planning, in the evaluation of alternatives, but they can also be applied in its strategic stages aiming to understand the problems. Eight LUTI models representing the categories of spatial interaction, econometric, and microsimulation models were assessed for their ability to represent the inner and interrelations of the transport, land-use and activity sub-systems, considering their level of aggregation, randomness, and dynamics of the modeled decisions. It was found that the conceptual bases of the selected models need to be better explicit to make their assumptions and limitations clearer to actors, planners, and modelers, turning not only their results, but also their construction process, especially the calibration and validation efforts, into useful tools for a better understanding of complex urban problems.
