A Land-Use/Transport interaction model for Austria

摘要

This paper presents an attempt to set up the land-use transport interaction model MARS (Metropolitan Activity Relocation Simulator) for a nation wide case study of Austria. The purpose of the model is to capture the most important interactions and feedback mechanisms between the land-use- and the transport system. To this end we adapted the urban MARS model. Particular attention was paid to the structural changes of the model and the estimation of the transport model parameters as well as the land-use model parameters, which are modelled with a gravity model approach. For this purpose we used the build-in optimizer of the modelling software Vensim by minimizing the sum of squared deviations between observed and predicted data. We present the model fit, estimated parameters and results of a first model run (30 years).
