Implementierung des integrierten Flächennutzungsmodells UrbanSim für den Grossraum Zürich: Ein Erfahrungsbericht

Abstract

Despite the importance of assessing long-term outcomes of planning decisions, there is a lack of appropriate tools for forecasting and comparing land use and transport scenarios. A new generation of integrated land use models has been developed over the last two decades, but so far only few field reports are available about their implementation and practical application. The article reports some early experiences made while setting up the land use model UrbanSim for the Greater Zurich area. It introduces the simulation framework and outlines the implementation process. Particular focus is given to data issues, as they constitute a crucial factor for the implementation. Representative of the models used for the simulation, the rent price and household location choice estimations are presented, interpreted and compared in detail. Finally, a more technical evaluation of UrbanSim’s software qualities as experienced by the implementer is being given.
