Due to more complex structures and an increased number of construction standards the planning of airports is getting more challenging. Hence, increasing importance for reusable tools in method development and subsystem coupling can be observed. These allow the development of subsystems with different modelling methods which are suitable for particular questions. Finally, coupling leads to the whole system. Goal of this work is to create a concept for method development and coupling in the area of mobility at airports (traffic infrastructure). In the second part of the dissertation this allows the implementation and testing of subsystems concerning mobility at airports.
