Table 3 shows that the proposed modifications significantly improve the operation of this intersection, beyond the
anticipated future base cases. As such, the proposed modifications are considered suitable to mitigate the impact of the
development proposal on this intersection.

4.10       Traffic Impact Assessment Summary
The development proposal does not significantly exacerbate traffic issues at the Hilton Terrace/Ernest Street intersection
(primarily the right turn from Ernest Street).

The Goodchap Street/Val Crescent intersection is expected to perform as well as, or better, than identified in the Road
Pro assessment, as the traffic generation is expected to be lower.

Right turns into and from the site will be restricted by extending traffic islands at the adjacent pedestrian refuge. U-turns
are restricted at this refuge through signage and are encouraged through signage (adjacent to the refuge) to occur at
Juron Street.

The development impact on the Eumundi Noosa Road/Goodchap Street intersection can be mitigated by reconfiguring
the approach lanes on Goodchap Street to provide an all movement lane and a dedicated right turn lane.

The proposed works are considered suitable to mitigate the development impact on the road network and encourage
suitable road operation.

5       Site Access – Design (Item 6)
The proposed site access has been reconfigured to a single access point. The driveway crossover is 7m wide Type B based
on IPWEAQ specifications. This driveway type and design is considered suitable to meet Probable Solution S1.2 of the
Driveways and Carparking Code and other relevant Council requirements.

Pedestrian and cyclist impacts of the proposed driveway are expected to consistent with other standard commercial
accesses.

Goodchap Street is a district collector road, and as such has the dual function of transport movement and access. Along
the site frontage of Goodchap Street, there are two pedestrian refuges, a bus stop on each side and a hospital which
would generate pedestrian movements to paths and public transport. As such, road user safety – particularly for
pedestrians and cyclists – is considered more important than transport movement/efficiency in the vicinity of the subject
site.
