Scales of Spatial Organization for Transportation
The above figure provides a perspective of the main elements structuring the organization of space at the local, regional and global levels. While the major nodes structuring spatial organization at the global level are gateways supported by port, airport and telecommunication activities, at the local level, employment and commercial activities, which tend to be agglomerated, are the main structuring elements. Each of these scales is also characterized by specific links and relations ranging from locally-based commuting to global trade flows.
