Sec. 167.5  Definitions.

    (a) Area to be avoided means a routing measure comprising an area 
within defined limits in which either navigation is particularly 
hazardous or it is exceptionally important to avoid casualties and which 
should be avoided by all ships or certain classes of ships.
    (b) Traffic separation scheme (TSS) means a designated routing 
measure which is aimed at the separation of opposing streams of traffic 
by appropriate means and by the establishment of traffic lanes.
    (c) Traffic lane means an area within defined limits in which one-
way traffic is established. Natural obstacles, including those forming 
separation zones, may constitute a boundary.
    (d) Separation zone or line means a zone or line separating the 
traffic lanes in which ships are proceeding in opposite or nearly 
opposite directions; or separating a traffic lane from the adjacent sea 
area; or separating traffic lanes designated for particular classes of 
ships proceeding in the same direction.
    (e) Precautionary area means a routing measure comprising an area 
within defined limits where ships must navigate with particular caution 
and within which the direction of traffic flow may be recommended.
    (f) Deep-water route means an internationally recognized routing 
measure primarily intended for use by ships that, because of their draft 
in relation to the available depth of water in the area concerned, 
require the use of such a route.
    (g) Two-way route means a route within defined limits inside which 
two-way traffic is established, aimed at providing safe passage of ships 
through waters where navigation is difficult or dangerous.
