What is it about?

On the one hand, conventional transport models are expensive, time-consuming and in most cases a black-box. On the other hand, urban planning frequently needs ex ante assessments of the effects of a large number of future policies. A System Dynamics based toolbox aims to bridge this gap. The toolbox consists of qualitative methods (Causal Loop Diagrams) as well as a quantitative simulation tool for urban land use and transport systems. The paper describes the different tools and presents lessons learnt and results from test cases.

Why is it important?

Decision making in complex systems like cities and urban regions needs adequate methods and tools. Our findings demonstrate the applicability and usefulness of the System Dynamics based approach in the context of urban transport and land use politics.

Perspectives

This paper gives a good overview and summary of my work concerning System Dynamics in transport planning and politics during the first decade of the 21st century.
