| Abstract: | Human history demonstrates that the movement of men and information has always been of paramount importance. The size of communities is determined by the territory that is readily accessible by movement capability. Using a version of Darwinian ideas in the form of Lotka's equations of competition between species as an analogy, air transport and other elements of the transportation infrastructure are examined. It is found that they exhibit extreme dynamic stability over time at all hierarchical levels. |
