that form part or the main trunk line system; all
roads leading to national ports, national seaports,
parks or coast-to-coast roads. National arterial
roads are classified into different groups from the

function

Bypasses around communities
countermeasures are aimed at improving
safety and reducing the volume of through
traffic inside the community. Where a
bypass can be justified, the most important
considerations are:
I. The opportunity should be taken to reinforce the road hierarchy by downgrading the old road to discourage through traffic;
II. Access to the bypass should be
restricted to only a few points where
safe intersections and spur roads can be provided to line the existing
network: Direct access from frontage land should not be permitted;
III. Provisions should be left for future expansion or development of the
community but such developments
should be served by service roads
and spur roads.
All of the above
Where a bypass cannot be justified,
countermeasures should be implemented
to slow down the speeds of through traffic
as it passes through the community or
trading centers as follows:
I. Warning signs and rumble strips can
be used to alert drivers about speed-
reducing devices ahead;
II. A series of road humps increasing in
height from 40 mm to around 80 mm
can be used gradually to slow down
traffic in pedestrian predominated
area;
III. Road narrowing (with due regard for
capacity needs) can be used to induce
lower speeds as traffic passes
through the community; and;
IV. In order to alert drivers that they are
entering a community, it is generally
regarded that some form of gateway
treatment on theapproaches is beneficial (e.g.,
substandard curve,tree lining, or even non-rigid
gate structure).
All of the above
