Commercial transportation and all its related stakeholders are faced with new challenges, both from the increasing concentration of urban population and areas, as well as from the ever increasing competition in the transportation services industry. Because the causes of the necessary restructuring in commercial transportation are very complex, this paper will define the parameters, influencing factors and resulting consequences as it applies to commercial transportation in the Vienna metropolitan area. It will include a systematic analysis of the interrelated effects on an economic and ecocologic, as well as on a social level. This method of analysis, using these three supporting elements, allows for a holistic approach that makes possible alternative logistic concepts that are both economically efficient and sustainable. Because small carriers, due to their supply function especially within the Vienna city limits, play such an important role in Vienna commercial transportation, they have been chosen as the starting point for this analysis. The conclusions resulting from this analysis are intended to provide the conceptual basis for an internet based order processing service with the project name "KTAK" ("Kleintransporteure auf Knopfdruck"). The "KTAK" concept can be viewed as an instrument that promotes both an increase in the operating efficiency for the service provider and an increase in the sustainability of innercity areas.
