Council has been contacted by local residents in relation
to safety concerns at the intersection of Warrambool Road, Coomburra Crescent
and Goondooloo Drive in Ocean Shores (see circled area on location map
below).
Investigation of NSW crash data shows two serious crashes
at this intersection. The first, in 2019, resulted in a fatality and,
the second in 2022, caused a serious injury.

Both incidents were multi-vehicle cross-traffic crashes
which involved vulnerable road users (a motorcyclist in 2019 and a pedal
cyclist in 2022). The fatal crash in 2019 involved a light truck
travelling south on Warrambool Road, striking a motorcyclist who was
travelling east across the intersection from Coomburra Cres to Goondooloo
Drive (see sketch below).

The following factors may have contributed to these
incidents (refer photos below):
· Topography and
geometry of intersection
Goondooloo Dr and Coomburra Cr run steeply uphill to meet
Warrambool Road and Warrambool Road runs downhill towards the Orana Road
roundabout. This, combined with the slight misalignment of Coomburra Cr
and Goondooloo Dr, limits driver sight distances at this intersection.

road topography
· Sun glare
Both incidents occurred approx. 2hrs prior to sunset,
impacting vehicles travelling in a westerly direction (e.g. vehicles
travelling from Goondooloo Dr to Coomburra Cr or vehicles turning down
Coomburra Cr).
· Road
infrastructure
There are existing Give Way signs on both side streets,
however they are not prominent and the existing line markings are
faded. There is also no channelisation of traffic on the side streets.
Speed has been suggested as a factor by the local
community but we do not have any data to support this at this time.

Proposed solution (refer sketch below)
The below solutions are intended to stagger the two minor
legs and tighten the entry angle from the Coomburra Cres. approach.
· New double
centre line to Warrambool Road to create a turning point for traffic and
discourage vehicles driving straight through the intersection.
· New line marking
and channelisation on Coomburra Crescent to prevent traffic driving straight
through onto Goondooloo Drive.
· Move Give Way
signage to more prominent locations.
· Potentially
change the give way to a stop (intersection sight distance is limited).
· Refresh all
existing line marking through the intersection.
