The IRPUD model of the eastern part of the Ruhr area is a dynamic simulation model of intraregional location
and mobility decisions in an urban region. It was developed in a project for the German Research Council
at the Institute of Spatial Planning of the University of Dortmund since 1977 and has been applied in several
projects for the European Commission and regional authorities, such as the EU projects
PROPOLIS (Planning and Research of Policies for Land Use and Transport for Increasing Urban
Sustainability) and STEPs (Scenarios for the Transport System and
Energy Supply and their Potential Effects), the project of the Institut f r Landes- und
Stadtentwicklungsforschung Nordrhein-Westfalen "Analysis of Central Constraints, Instruments
and Goal Criteria for state transport planning in North-Rhine Westphalia" and the project
Ruhr Area 2050: Modelling of the Energy Transition in the Ruhr Area
funded by the Mercator Foundation.
The IRPUD model
The IRPUD model has been continuously further developed in the course of time. The most recent developments include the extension of the study area by external zones and the consideration of detailed measures to optimise the fare system of public transport. Descriptions of the model according to the state of its development at the time of writing are contained in
