Une insularité sans îles ? 
De l’insularité topographique à l’insularité topologique en milieu continental. Le rôle des réseaux de transports

Abstract : Regarded as obvious, does the island, as a concept, concern only topographical spaces? Isislandification of continental spaces also possible in a topological space, notably by the use oftransportation networks?In the first hand, our proposed method here first underlines epistemological foundations of insularityconcept. It shows numerous markers of topographical insularity (fragmentation, subordination,peripheral location, vulnerability) then deepens their meanings according to transport geographer:territorial or spatial continuity solutions, multiple breakings in speeds and mobile rhythms, perimeterconstraint.On the other hand, we examine a possible translation of insularity concept in a continentalenvironment. Defined as a socio-spatial creation, based on actors’ practices, insularity can be seen as aproduct of a simple dis-continuity, for example in a skiing resort where roads or rail access permitsterritorial continuity. On the opposite, the network-territory is closed by the exclusive use of perimeter.The more complex networks insularity generates archipelagos (case of hub-and-spokes networks for airand HST networks) or a mixed territoriality, between island and archipelago (case of aerotropolis).
