Mobility in its many forms has always been part of evolution in nature and civilisation. Without mobility, there is no progress through exchange of goods and information or even genetic material; too much mobility, on the other hand, makes it difficult to stay in one location, which is necessary for productivity. Mobility in the form of the physi-cal movement of people and goods requires energy for motion, which it stores in the objects moved. If these mobilised objects are not moved in the paths planned for them, collisions, contaminations or explosions may result. How serious such inci-dents are depends particularly on the number of people and type of goods being car-ried, and on the speed-dependent energy of these objects. As a result of such inci-dents, the traffic flow is obstructed. To carry out objective research, we first of all need to define the phenomenon of mobility and its properties in a conceptual context. Finding terms to describe these phenomena will also help to structure them. Only on this basis can we provide a binding definition and use modelling for comparisons, assessment and quantification.
