PDF Map)World Main Road and Rail NetworksThe structure of the global land transport network is a function
on the density and intensity of economic activities as well as
efforts made to access inland resources. It is important to
underline that while the global road and rail
networks appear to be integrated and interconnected, this is far
from being the case. Road networks are designed to service local and
regional flows and only a few corridors are used for long distance
trade. Most rail networks are national with limited international
services with the exception of Europe and North America. Still,
different gauges are serious impediments to the setting of a true
pan-European rail network. The North American rail network is
integrated but segments of the network are owned by different
carriers.
