Traffic Report - responses 11 to 16

Information Required
11.       Provide a survey plan which indicates the dimensions of:
          11.1. the existing formation in Kabi Road between the intersection with Cootharaba Road and the site
                entrance,
          11.2. the existing formation of the intersection of Kabi Road and Cootharaba Road, and
          11.3. roadside and overhanging vegetation.
A feature and level survey has now been undertaken by JFP Urban Consultants, with the information to be
provided to Council as part of this response.
12.       Provide additional comment and swept paths from the Traffic Consultant which:
          12.1. includes swept paths based on the survey
          12.2. assesses the current formation extents as determined by the survey and includes
                recommendations on any necessary improvements to ensure that the concerns have been
                suitably addressed
          12.3. includes a risk assessment/road safety audit based on the proposed development, existing road
                conditions and proposed improvements
Swept path assessments have been updated on the feature and level survey, with the swept paths
discussed in Section 6.3 of this report.
A turn warrant assessment indicates that the most basic intersection treatment, a BAR / BAL is appropriate
for the Kabi Road / Cootharaba Road intersection, see Section 5.5 of this report. The current intersection
does not meet these requirements, with no widening of the Cootharaba Road carriageway to facilitate
passing. As the development is not expected to add to left turn movements into Kabi Road, it is suggested
that upgrade works could include:
          Provision of a BAR treatment on Cootharaba Road.
          Upgrade of Kabi Road, along its length and including at the intersection, to 6.2m pavement width.
Of the above, it is noted that the BAR treatment is not triggered by this development and represents the
minimum intersection design requirement of AUSTROADS.
13.       Provide an assessment of the existing formation of Kabi Road and the intersection of Kabi Road with
          Cootharaba Road. The assessment must be based on pavement testing of the existing formation and
          include recommendations on any improvement works necessary to cater for the proposed vehicle
          movements
Please see Section 5.4 of this report for further detail resulting in a recommended upgrade to a 6.2m
pavement width. Alternately it would be possible to limit the use of the site such that upgrade of Kabi Road
would not be required, however the site operator does not want to explore this option at this point in time.
