ILUMASS: Integrated Land-Use Modelling and Transportation System Simulation (2001-2007)

In the ILUMASS project (Integrated Land Use Modelling and Transportation System Simulation), seven German research institutes developed an integrated, end-to-end microscopic simulation model of land use, transport and environmental impacts in urban regions. The ILUMASS model is divided into three model components:

(1) The land use component is based on the land use part of the IRPUD model developed at the Institute of Spatial Planning at the University of Dortmund, but is microscopically analogous to the transport parts in ILUMASS. The land use part contains sub-models of demographic development, household structure, business development cycles, locations of residential and commercial buildings, small-scale job mobility of employees in a model of the regional labour market and small-scale household mobility in a model of the regional housing market.

2) The transport part of ILUMASS models the daily mobility of people based on a microscopic model for generating activity patterns and the resulting routes as well as freight flows coupled with a microscopic traffic flow model.

(3) The environmental part of ILUMASS models the environmental impacts of modelled transport and land use in terms of greenhouse gas emissions, air pollution, traffic noise and visible impacts of transport and selected land use emissions.

The ILUMASS model was calibrated with data from the Dortmund urban region in the eastern Ruhr area and tested in experimental scenarios of land use and transport development in the region.

ILUMASS was a collaboration of seven research institutions in Germany, the Institute for Spatial Planning at the University of Dortmund (IRPUD), Spiekermann & Wegener, Stadt- und Regionalforschung (S&W), Dortmund, the Centre for Applied Informatics at the University of Cologne (ZAIK), the Institute for Urban Planning and Urban Transport (ISB) at RWTH Aachen University, the Institute for Theoretical Psychology at the Otto Friedrich University in Bamberg, the Department of Environmentally Compatible Infrastructure Planning and Urban Development (LUIS) at the University of Wuppertal and the Institute of Transport Research at the German Aerospace Center (DLR), Berlin, under the project management of DLR.

The small ILUMASS-Modell

For test purposes, S&W implemented the small ILUMASS model in cooperation with the Institute of Spatial Planning at the University of Dortmund, a reduced version of the ILUMASS model in which the elaborate microscopic traffic simulation was replaced by the existing more aggregated traffic model of the IRPUD model. The small ILUMASS model is described in
