Modal Corridors in an Urban Region
Corridors are multimodal entities as they represent the accumulation
of transport infrastructures concerning several modes. Thus, within
an urban corridor there is an overlay of modal
corridors, each having a market share depending on the basic
geography of the region, the respective level of infrastructure
investment and the types of flows involved (passengers or
An important component of modal corridors are
which regulate flows. Modal corridors interact with one another as some
are directly competing while other are complimentary. For instance, in a specific
region fluvial and land corridors could be competing for attracting
freight traffic while road and rail could be complementary
(focusing on passengers and freight respectively).
- The maritime corridor is a set of non discrete paths
(maritime routes) between regional maritime hub centers, which
are places of transshipment and logistics.
- Fluvial corridors are
a mix of discrete and non discrete paths, depending if canals,
rivers and seacoasts are considered individually. They are an overlay of canals, waterways and fluvial
ports along an axis corresponding to a natural penetration
corridor like a major river or a set of interlinked coastal
cities. Containerization has enabled the development of new
forms of fluvial shipping and enabled several ports (mostly in
Western Europe and China) to service their hinterlands through
- Land corridors are the foundation of a regional economy
and provide a support to land movements through discrete paths.
- Air corridors correspond to the navigation lanes of air traffic.
