They are systems of ways for ships in this
water-part of the world where the density of
traffic is great or where freedom of movement of
shipping is inhibited by restricted sea-room, the
existence of obstructions to navigation, limited
depths or undesired meteorological conditions.

According to Part A of the IMO publication,
Ships' Routeing, sets forth the General
Provisions on Ships Routeing (GPSR)
(resolution A.572(14), as amended) we may
distinguish causes as follows

It helps navigators in the organization of
traffic flow within or around areas where
navigation by all ships or by certain classes of
ship carrying specific certain cargos or types
and big quantities of bunker fuel is dangerous or
undesirable.

It reduces the danger of collision between
crossing traffic and shipping in established
traffic lanes and makes the traffic flow easier
in areas of concentrated offshore exploration or
exploitation.

It is used for the purpose for preventing or
reducing the risk of pollution or other damage to
the marine environment caused by ships colliding
or grounding in or near environmentally sensitive
areas.

Some conditions must be taken into account

• various weather,
• if water areas are ice-free,
• necessity of extraordinary manoeuvres,
• if under-keel clearance is adequate,
• the effects of meteorological and tidal influence
  on water depths.

It could be created in canals or between natural
obstructions (as islands, shoals or rocks), which
are restricting free movement and providing a
natural division for opposing traffic streams .
We use lines, because there is too narrow for
separation schemes.

If there is enough place, there is traffic
separation by separation zone and line...

We can meet some routes in form sectorial
division of near traffic separation schemes
approaching to focal point.

they should follow as closely as possible
existing patterns of flow, course alternations
along the route should be as few as possible, and
convergence areas and route junctions should be
kept to a minimum and should be as widely
separated from each other as possible

What else should we know about routes
29
Ships Routeing Systems
What else should we know about routes

• they should be designed to allow optimum use of
  aids to navigation in the area
• route junctions and convergence areas should not
  be placed where crossing traffic is expected to
  be heavy
