This work provides a foundation to make heterogeneous alternatives for mobility (transportation modes) comparable in the context of sustainability and providing possibilities to also compare them in other contexts such as costs or flexibility. The key to a successful comparison of such transportation modes is stated as the selection of semantically suitable key performance indicators (KPI) and a reasonable decision analysis method, which will be covered throughout this work. A set of KPIs is selected by considering various existing indicators, like indicators for measuring resource consumption or air pollution. This work provides a method for comparing the relative sustainability or any other desired dimension, given the requirement that a suitable set of KPIs is selected, of multiple modes of personal transportation by using key performance indicators and the multi-criteria decision analysis method PROMETHEE II. In addition to the introduced objective decision support, the authors also provide a way to enable subjective decision support by taking the preference-based model of an individual decision-maker into account. A method to enable individual preference based matchmaking is introduced to provide the mathematical foundation for mapping each individual to their subjectively optimal transportation mode. Some possible practical use cases which are able to create real world added value by automated appliance of the introduced models are given by the authors as well..
