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.
The value of time in the transport economy corresponds to how willing people are to pay, in order to save time. It offers an explanation of the choices people make between different modes of transport after weighing up the financial versus time costs. It is also used to plan and to financially justify a choice of investments made on the basis of time saved by the new infrastructure.
Reversible mobilities are forms of specific movement made possible by rapid transport network systems. They are made over long distances, with outward and return journeys that are undertaken closely together in time. They are also limited in terms of social mobility and their relationship with otherness.
Born in 1938, Michel Bassand is a Swiss sociologist. He was successively a professor at the Université de Genève and at the Ecole Polytechnique Fédérale de Lausanne (EPFL). A specialist in urban issues, he was responsible for a highly-original theory of mobility as a completely social phenomenon, whose different expressions form a complete system.
