The master thesis in hand deals with operating range and attractiveness ratio of S-Bahn lines S61, S6 and S7.The analysis center of attention is focused on commuter traffic in Western Styria.On the one hand the range of train stations is explored while on the other hand the potential of rail passengers at a particular station is investigated. Besides, S-Bahn stations are evaluated by their attractiveness for passengers according to the follow-ing parameters:?number of S-Bahn connections?number of bus connections?supply of primary needs?supply of additional needs?fare zonesFor accomplishing reasons, firstly the concepts of passenger, commuter traffic and S-Bahn are explained in detail. Secondly, the area of investigation (Western Styria) is covered by means of S-Bahn development, infrastructure and it?s central places. Finally, abovementioned influencing parameters are analysed and integrated into a distance depending network by the created model. Ranges of S-Bahn stations, de-pending on the attractiveness for passengers, rise as a result of this process. The coverage is divided into catchment areas accessible on foot or motorised, which are combined with data of professional commuters to calculate the capability of the investigated S-Bahn lines with support of ridership data. ArcGis 10.1, a programme of software developer Esri, is used to implement the presented approach.
