Traffic Impact Assessment




4.             TRAFFIC DESIGN REVIEW
4.1            ACCESS
               The proposed vehicular access arrangements are summarised below:
                    existing crossover on Memorial Drive to be retained and unchanged;
                    all existing crossovers on Pelican Street to be removed and replaced with a single 7m ‘Type B’
                     crossover for access to the proposed deck carpark; and
                    a new 6m ‘Type A’ crossover to be provided on Doonella Street for access to the under croft carpark.
               Both proposed new driveway crossovers will be designed in accordance with Council’s standard drawing
               for driveways (RS-051), with appropriate flares. Importantly, the combination of introducing new crossovers
               and removing existing crossovers results in no net loss in on-street parking in proximity to the subject site.
               It is acknowledged that the proposed new crossovers do not achieve minimum sight distance requirements
               for access driveways in accordance with Australian Standards. That said, we are of the view that the
               proposed arrangement is acceptable for the following reasons:
                    it is consistent with the existing situation (i.e. on-street parking bays current abut each driveway flare);
                    it is located within a low speed environment (i.e. 40km/h); and
                    it is located within a town centre environment.
               Based on the above, we are of the view that that proposed access arrangement is acceptable from a traffic
               engineering perspective.

4.2            CAR PARK LAYOUT
               The proposed parking layout has been reviewed against the Australian Standards. The key features of the
               parking area are displayed in Table 4.1 below.

               Based on the above, we are of the view that the only non-compliant element of the proposed new car
               parking areas is the servicing aisle width on the deck car park. However, a swept path assessment (refer
               Section 4.3) has confirm that the proposed arrangement could adequately accommodate waste truck
               manoeuvring. That said, service vehicles will need to utilise the full width of the service aisle to access the
               loading dock and as such, it is recommended that the deck car park is restricted to staff parking only.
               Based on the above, and pending the aforementioned recommendation, we are of the view that the
               proposed car park layout is acceptable from a traffic engineering perspective.
