Traffic Signal Design – Appendix D Location & Dimensions of Components
Where necessary, the stop line may be
set back further than normal to ensure
that it is clear of any conflicting turning
movements. In this situation a setback
of the stop line of up to 10m
from the prolongation of the kerb line
of the cross street is acceptable. Any
distance greater than 10m must be
approved by the Manager, Network
Operations.
The stop line should be at least 10.0m
from the starting lantern. However, If
this distance cannot be achieved, an
absolute minimum of 6.0m is permitted
(the mounting height of the lantern
assembly must be lowered in this
instance.
1.7 POSTS (INCLUDING MAST ARMS AND POLES)
Post types 1, 2, 4, 5, 6, 9 & 13 are located a minimum
of 1.0 m from the kerb. This dimension does not
need to be shown on the design layout. Any offset
other than 1.0 m must be shown. Distances are
measured to the centre of the post.
Post types 3, 10, 11 & 12 are located at the rear of
the footway with a minimum offset of 3.0m from the
kerb, unless protection is provided or an exemption
given. When an exemption is given, the posts are
located a minimum of 1.0 m from the kerb.
Post types 14 and 15 (Multi-function Poles) are
located a minimum of 1.0 m from the kerb if the fully
loaded weight does not exceed 700kg. If above 700kg,
they are located at the rear of the footway with a
minimum offset of 3.0m from the kerb, unless
protection is provided or an exemption given (See
Section 9.1.1 in Posts for exemptions).
The primary post is located 0.5 m beyond the front
edge of the stop line, irrespective of whether a
marked foot crossing is provided or not.
NB: For mid-block marked foot crossings, the primary
post is located on the front line of the stop line.
