Flughafen- und Zugangsverkehrsmittelwahl in Deutschland - Ein verallgemeinerter Nested Logit-Ansatz

The purpose of this paper is to present an airport and access mode choice model based on discrete choice theory. In particular, a nested logit-model approach is employed and alternatives are based on so-called "airport categories", which were formed from a demand-oriented point of view. For this purpose a cluster technique called Kohonen’s Self Organizing Maps was used. Therefore, the model is applicable to any number of specific airports and combinations of airports and access modes permitting an evaluation of future scenarios not existing today with regard to airports and accessibility. Therefore, this approach is entiteled as “generalized nested logit model”. Market segments are classified regarding destination type and travel purpose. Destination types are divided into domestic, European and intercontinental. With respect to travel purposes private and business trips are distinguished. The market segment of private air travel to European destinations is further subdivided into short stay and holiday trips.
