5.4        Kabi Road Carriageway: Development Impacts
To estimate the likely two-day traffic volume on Kabi Road with the addition of development traffic, the
daily traffic volume forecast from Section 3 of this report has been added to the recorded existing two-way
traffic volumes (average). The anticipated two-way traffic flow on Kabi Road following completion of the
development is provided in Table 4.

Table 4: Summary of Kabi Road Daily Two-Way Traffic Volume Estimates: Vehicles Per Day




Assuming full occupation of the camp at all times, the peak forecast two-way traffic volume on Kabi Road
is 403 vehicles per day. The forecast daily volume ranges from 73 vehicles per day, with an average
167 vehicles per day.
In considering the requirements for the roadway in Kabi Road, reference has been made to the
AUSTROADS document Guide to Road Design Part 3: Geometric Design which at Table 4.5 includes
information on single carriageway widths on rural roads. This is reproduced at Table 5, below.

Table 5: Reproduction of Table 4.5 from AUSTROADS Part 3




As can be seen from the above Table, for a forecast maximum two-way traffic flow of 403 vehicles per day,
the recommended carriageway width is 6.2m.
