Referecence Document Traffic Engineering Assessment Report 22 March 2023 131998.98121.5

A feature and level survey has been completed along the length of Kabi Road which has identified the
following:
        The existing sealed width of the roadway varies around 4.7m – 5.7m.
        There is an existing constraint of the culvert width to the eastern end of Kabi Road, with the sealed
         width some 5.6m at this location.
        Canopy over the roadway has been generally identified in the survey, as requested.
It is recommended that, with the exception of the section over the culvert which may be narrower due to
constraints of the culvert, Kabi Road be upgraded to a typical 6.2m seal width in accordance with the
AUSTROADS requirement.
Alternately, it would be possible to limit the operations of the proposed facility to reasonably expect less
than 150vpd on Kabi Road for the peak-repeatable event. This could be facilitated by limiting group sizes
outside of school camp operations. This would enable the existing carriageway of Kabi Road to
accommodate the proposed site operations. It is, however, understood that this is not an option which the
proposed site operator wishes to explore at this time.

5.5        Cootharaba Road / Kabi Road Intersection: Development Impacts
Introduction
There are two ways to determine the requirements for an intersection upgrade:
    1. Assessment based on Turn Warrants.
    2. Assessment based on calculated intersection operation.
These are both discussed below.

Turn Warrant Assessment
Figure 6 has been prepared to reproduce the Turn Warrants assessment requirement for an intersection
where the posted traffic speed is between 70km/hr and 100km/hr. This is reproduced from AUSTROADS
Guide to Traffic Management Part 6: Intersection, Interchanges and Crossing Management at Figure 3.25.
