Traffic has a strong influence on society and the environment. Statements about its development are therefore highly relevant politically and socially and can - due to the complexity of the interrelationships - often only be made by means of traffic models. The "Traffic Modeling" team develops on the one hand specific theoretical model approaches for this purpose and on the other hand implements them in concrete practical model applications. In addition to modeling passenger traffic, the team also analyzes the economic effects of traffic changes.
