Modes of Territorial Occupation by Transport Networks

• Clearly defined and delimited. Road and rail networks are the most relevant examples of this mode of territorial occupation with a well established land ownership along their paths. This implies only one possible use and other functions are not possible. Access is only available to the modes using the network.
• Vaguely defined and delimited. Most maritime and air corridors are vaguely defined as they often involve only a right of way. Multiple use of that space are thus permitted. For instance, a maritime corridor can overlap a fishing zone. However, air and port terminals have specific land ownership.
• Without definition. In many telecommunication network, overlapping is frequent and the only authorization required is the right to broadcast from a specific location using a specific frequency. Most cellular networks are established by building a number of broadcast points, each creating its own telecommunication "cell". The overlay of all these cells creates the illusion of a contiguous service. "No service" zones are also possible.
