                                                       Proposed Mixed Use Development, 30-32 Doonella Road, Tewantin
                                                                           Parking & Traffic Impact Assessment Report



Figure 5-5 AUL(s) turn treatment layout for entry driveway




The existing road shoulder is approximately 2.5m wide, so to provide a 3.0m wide turn lane for 5m, plus the
width of the driveway would require a minor realignment of the kerb and channel. This could be achieved as
part of the new driveway crossover and removal of the existing driveway crossover at the same location,
which requires removal and reinstatement of kerb and channel anyway. The only consideration is that the
alignment of the kerb will be 0.5m from the current alignment.
Whether or not the tapered line, broken continuity line and pavement arrows are warranted to provide a
formal AUL treatment or even if desirable from Council’s perspective for a private development of this size
and nature is not clear. Precedent in the area appears to be simply providing a road shoulder, and not formal
turning lanes.
Given the adjacent parking and residential driveway within the taper, and the fact that there would be
adequate shoulder space available (as per the AUL(s) layout), the recommended solution is to provide the
3.0m wide road shoulder utilising the existing adequate deceleration space provided by the existing parking
ban and adjacent driveway, and retain the edge line as is without formalising a left turn lane.
The projected increase in traffic activity as a consequence of the development proposal is minimal and will
not have any unacceptable consequences to traffic in terms of road network capacity.
