At PLANUM, we use macro- and microscopic traffic models to analyze traffic flows, impacts, and opportunities resulting from changes in traffic routing. These models are particularly useful when they cover not only the immediate planning area but all of Austria or, as in our case, large parts of Europe.


At PLANUM, Patrick Stern is one of the people responsible for developing and calibrating the models, as well as implementing the necessary data. He applies the model in many projects, thereby enabling a well-founded assessment of the impacts of various measures. It was also used in the SMAC research project—which focuses on sustainable airport access—and was supplemented by additional research findings.
