Mobility means the more or less regular change of place while maintaining the place of residence.

Mobility arises from the fact that certain activities are (have to be) taken care of out of home. This is how mobility can be traced back to individual requirements during its development. The overcoming of space is principally not dependent on any means of transport, the possibility of mobility is determined by individual, social, spatial and temporal conditions (fundamentals); traffic participation can be defined as a change of place, which is referred to as “trip”.
