Mobility or mobilities: Terrestrial, virtual and aerial categories or entities?

This article attempts to assess the three leading categories of mobility: terrestrial, virtual and aerial, in order to see whether they constitute categories of a single entity of mobility, or alternatively, they constitute three distinct entities of mobility. This exercise is of significance because of the tendency to refer to ‘mobility’ in a rather general sense. Coping with this question, we will, first, put it within a review of relevant concepts and structures. Then, we will elaborate on the distinct features of each of the three mobility categories through their comparison, highlighting mainly differences among them. This will be followed by a presentation of a somehow opposite perspective through the examination of convergences among the three categories of mobility. These two discussions will lead us to view mobility as one single entity consisting of three categories, since all the three categories are IT-based and IT-dependent, and given that they all share a similar model of mobility cycles for both moving people and mobility systems. Using this approach we will compare terrestrial public and personal mobilities, as well as aerial and virtual mobilities, followed by a discussion on implications of a single general mobility model.

Research highlights
► There are numerous differences between the three categories of mobility: terrestrial, virtual and areal.
► The three categories converge, though, since all the three categories are IT-based and IT-dependent.
► The three categories further converge since they all share a similar model of mobility cycles for both moving people and mobility systems.
► We suggest to view mobility as one single entity consisting of three categories.
