This appendix is a series of maps showing the hierarchy of roads in terms of strategic importance and traffic volumes.
The
roads within the District are classifies according to a hierarchical
system, based on the function of each road, and the need for that
road's capacities and capabilities to efficiently fulfil that function.
The classification of roads determines their management in regard to
land use and subdivision. The 'higher' the classification, the greater
the management emphasis is placed on enhancing the movement of through
traffic; the 'lower' the classification, the greater the emphasis on
access, and on pedestrian, parking and servicing needs.
The roading classification system applied to roads within the District is as follows:
State Highways
These
routes form part of the network of nationally or regionally important
arterial roads managed by Transit New Zealand. These routes
predominantly carry through-traffic, and carry the major traffic
movements in and out of the District, usually requiring a road reserve
width of 20 m.
District Arterials
These
roads cater for traffic movement between the major areas of the
District. Again, traffic management of these roads seeks to facilitate
traffic movement, and usually requires a road reserve width of 20 m.
Collector Roads
These
roads collect and distribute traffic to and from the arterial road
network, and often act as links between two arterials. These roads also
act as local main roads supplementing the district arterials.
Through-traffic generally makes up a high proportion of the traffic
flow. Road reserve widths are normally between17 m and 20 m.
Local Roads
These
roads provide direct access to adjoining properties. Many local roads,
except cul-de-sacs, also collect and distribute traffic to and from
other local roads within the District. Traffic flows are usually low,
and it is desirable to minimise through or extraneous traffic because
of the effects on the adjoining environment and amenities, and the
limited physical capabilities of such roads. Road reserve widths range
from 12 m for short cul-de-sacs, to 20 m for other local roads.
There
may be other types of roads that do not come within the overall
hierarchy. These may include services lanes, which provide safe or rear
access to any site from roads in business areas, to minor no-exit
access routes in rural areas. In addition, there are a relatively large
number of unformed roads throughout the District (known as 'paper
roads') which have no active role in the roading network.
