The use of innovative mobility services is expected to contribute to the vision of sustainable mobility. The effects of these new mobility services should be determined empirically or based on models. Knowledge of the type and extent of these effects is currently still very limited. On the basis of a well-founded impact assessment, an evaluation of the contributions to a positive overall economic development can then be established. The article uses two practical examples to create such a macroeconomic evaluation and provides information for a standardised procedure to be developed in the future.
