Applications of integrated models of land use and transport: A comparison of ITLUP and UrbanSim land use models

摘要: The spatial distribution of regional employment and households are essential inputs to predicting transportation system performance. In this paper we compare relatively common gravity-based Integrated Transportation Land Use Planning (ITLUP)-type models to the highly disaggregate and more recent approach enshrined in UrbanSim. Land use and transportation system data from Austin, Texas provide the test-beds. The goal of this research is to find the best fit model systems for MPOs of differing resources and needs. This paper highlights the strengths and limitations of these models in the context of data requirements, calibration and presentation of results.
