                                                                                                   Traffic Report Rev B



In order to provide adequate visibility towards pedestrians approaching the exit (northern) driveway onto Goodchap
Street, a triangular area which is 2.0m wide and 2.5m inside the property boundary, adjacent to both sides of this
driveway, should be kept clear of vertical obstructions (in accordance with AS2890.1 Figure 3.3). This is a minor design
refinement which it is anticipated could reasonably be addressed in response to a condition of the approval, at detailed
design stage.

3.1.2   Val Crescent Driveway
The access to the basement car park and servicing area is proposed on Val Crescent, at the northern site boundary. In
this location, a minimum of 6m separation to the adjacent intersection of Val Crescent and Goodchap Street is achieved,
in accordance with the requirements of AS2890.1.
A sightline assessment has been undertaken, in light of the proximity of the proposed driveway to adjacent road features.
In order to achieve adequate sight distance from the exit side of the driveway towards traffic turning left from Goodchap
Street into Val Crescent, it has been recommended that the area as identified in Figure 3.1.2 below be kept clear of any
obstructions, including fences or landscaping. This will provide approximately 40m of stopping sight distance (SSD)
which achieves the desirable minimum assuming a vehicle approach speed of 40km/hr and a reaction time of 2 seconds,
based upon the provisions of Austroads Guide to Road Design Part 3 – Geometric Design (Table 5.4). This would also
exceed the minimum SSD stipulated in Figure 3.2 of AS2890.1 assuming a frontage road speed of 40km/hr, which is
35m.
Sight distance from the exit side of the driveway towards traffic approaching from the west (i.e. the bend in Val
Crescent) would also exceed the 35m – 40m minimum required under the provisions of Austroads Guide to Road
Design and AS2890.1, assuming that vehicles take this bend at 40km/hr or slower. Given the radius of this bend, it is
considered highly unlikely that traffic would travel around this corner at approximately 30km/hr.
