Blacktown Road Hierarchy

Arterial roads carry longer distance traffic to, from and across the urban area.  They have connections with the state or national road network running between urban areas and operate as truck routes and carry heavy goods vehicles. These roads generally carry more than 15,000 vehicles each day.  The level of service for traffic flow should encourage rather than discourage traffic from using these roads.

Sub-Arterial roads carry traffic between industrial, commercial and residential areas. These roads generally form a grid with roads spaced around 1.5 kilometres apart and link specific land-use areas or “cells”.  These roads carry between 6,000 and 20,000 vehicles each day including heavy goods vehicles.

Major Collector roads link Local roads to the Arterial and Sub-Arterial roads. These roads carry between 5,000 and 10,000 vehicles each day and a 50 km/h speed limit will normally apply.While heavy vehicles are discouraged bus services are allowed on these roads.

Minor Collector roads also link the Local roads within a specific land-use cell to Major Collector roads. The route of the Minor Collector roads discourages through traffic so that the cell formed by the grid only carries traffic belonging to or serving the cell. These roads usually carry less than 4,000 vehicles each day although they may carry up to 5,000 vehicle each day. Generally, heavy good vehicles and trucks would not use these roads.

Local, or, Access roads provide access to individual properties. An upper speed limit of 50 km/h will normally apply. These roads usually carry less than 1,500 to 2,000 vehicles each day.
