1 Introduction
1.1 Background
Transport Engineering Studies has been commissioned by City Projects Office (CPO) to
undertake an Existing Stage Road Safety Audit of Hellawell Road (at The Avenue and
Borella Road), Runcorn. The purpose of this road safety audit is to provide an independent
assessment of any road safety risks that may be present and to provide advice on options to
mitigate identified risks.
1.2 Road Safety Risk Rating
The audit was completed in accordance with the requirements of Austroads, Guide to Road
Safety: Part 6 Road Safety Audit, 2009. The audit report generally follows the format and
topics outlined in the Austroads Checklist 6 for an existing road audit.
Risk rating of safety issues is defined as per Austroads Part 6 Table 4.4. Table 1.1 below
outlines the severity and likelihood relationship consistently used to identify a risk rating.
Actions required in response to these ratings are recommended as follows:
INTOLERABLE: Must be corrected as quickly as possible.
HIGH: Should be corrected or the risk significantly reduced, regardless of cost.
MEDIUM: Should be corrected or the risk significantly reduced, if the treatment cost
is moderate.
LOW: Should be corrected or the risk reduced, if the treatment cost is low.
VERY LOW: Deficiencies identified in the standard or the positioning of traffic
control devices which, while unlikely to directly increase risk significantly have very
low treatment cost and therefore should be mitigated with routine maintenance
actions.

Table 1.1: Risk Rating Matrix
Severity Frequency
Frequent Probable Occasional Improbable
Once/ week Once/ year 5-10 years <every 10 years
Catastrophic Likely multiple deaths Intolerable Intolerable Intolerable High
Serious Death or serious injury Intolerable Intolerable High Medium
Minor Minor injury Intolerable High Medium Low
Limited Trivial injury/property damaged High Medium Low Very Low
The above relies on professional engineering judgement of the audit team. Further
information on determining risk ratings based on probability, severity and level of risk can be
found in Austroads Part 6 Section 4.8 C.
1.3 Responding To Audit Findings
The Austroads’ Guide to Road Safety Part 6: Road Safety Audit clearly outlines that the
client is not under any obligation to accept any or all of this road safety audit’s
recommendations. It should be noted that the recommendations outlined herein may not be
the only option for mitigating the risk of a particular issue, or be the most cost effective
option. It is good practice to document the reason(s) behind rejecting any findings from a
road safety audit should such a decision be made.
1.4 Audit Trigger
Transport Engineering Studies understands that the trigger to undertake this Road Safety
Audit has been at the discretion of the CPO project team. Undertaking independent road
safety auditing at various stages throughout the engineering design process ensures that
safety is considered as an integral part of the design and planning process.

3.
Hellawell
Road/Luke Close
Intersection
Kerb ramps on either side of Luke Close are poorly
aligned.
This makes it difficult for persons with vision
impairment to cross at this location and increases the
risk of pedestrian/vehicle collisions.
LO
W Consider realigning the pathway
and/or kerb ramps so that the
ramps are aligned.
Kerb ramps will be
reconstructed on new road
alignment for 3.0m wide shared
path

Intersection
Power pole located in close proximity to the traffic
carrying lane.
Increased severity of injury in the event of an errant
vehicle leaving the road at this location.
ME
DIU
M
Consider relocation or protection
of the power pole.
Power pole will be relocated due
to road widening. A minimum of
0.6m clearance from nominal
kerb face to the new pole will be
provided.

Consider removing existing
signage (and installing wayfinding
signage if deemed
necessary/advantageous).
Signs to be removed and

6. Hellawell
Road/Peter Court
Kerb ramps on either side of Peter Court are poorly

Consider (in order of
precedence):
a) improving intersection

southbound bicycle lane
further upstream of the
intersection and directing
cyclists to the footpath
Intersection is being upgraded

Hellawell Road
Pedestrian Refuge
(west of Borella

Inappropriate use of D4-3 Width marker sign for
delineation of concrete islands.
Whilst unlikely to be a hazard in isolation, in general
the incorrect use of hazard signage dilutes their
meaning and breaks the basic road design rules of
consistency.

Consider replacement of signage
with D4-3 Hazard Markers (on
