This is a list of essential terms of the mobility. Your contributions help keep the list fresh and up to date: you can propose new words or redefine those already on the list by refining or supplementing their current definitions. Each lexicon entry comes with both a brief definition and a more detailed explanation, accompanied by a bibliography. Some definitions include suggestions for further discussion or research opportunities. Wherever a lexicon entry appears on the site, its brief definition is available as well, and if so required, you can follow a link to see the complete definition.
Defining mobility is especially important because the term is highly polysemous. When geographers use the term mobility, they do so to evoke the act of moving across a space. As such, they aren’t speaking about the same thing as traffic engineers or sociologists, who both use this notion to refer, respectively, to transport flows and self-transformation. This diversity of meanings, far from adding richness to the concept, is an obstacle to understanding. Clearly, when mobility is mentioned, we don't know exactly what’s being referred to: it all depends on one’s disciplinary background. This is the result of how the concept of mobility originated and evolved, which is what we are going to discuss here. Over the past two decades, several authors have proposed inclusive definitions of mobility to help overcome the constraints of disciplinary segmentations.
