ONE CITY, THREE MODELS - COMPARISON OF LAND-USE TRANSPORT POLICY SIMULATION-MODELS FOR DORTMUND

The paper reports on simulation experiments conducted by the International Study Group on Land-Use/Transport Interaction (ISGLUTI) for the metropolitan region of Dortmund in the Federal Republic of Germany. Three land-use/transport simulation models were applied to the Dortmund region: the DORTMUND model developed at the University of Dortmund, the LILT model being used at University College London and the MEPLAN package developed by Marcial Echenique & Partners in Cambridge. The three models are briefly characterized and their ex-post forecasts are compared with the actual development of the region. The final section of the paper compares how the three models respond to a common set of assumptions and policies from the fields of land-use control, traffic management and transport investment. The differences in model response give insights into the validity of the theoretical foundations and internal structure of the models.
