INTRODUCTION 1.1 Scope of Audit A Road Safety Audit is a formal, systematic, assessment of the potential road safety risks associated with a new road project or road improvement project conducted by an independent qualified audit team. The assessment considers all road users and suggests measures to eliminate or mitigate any risks identified by the audit team. This Road Safety Audit has been conducted following the general principles detailed in Austroads Guide to Road Safety Part 6: Road Safety Audit and in accordance with the requirements contained in the Main Roads Western Australia Policy and Guidelines for Road Safety Audit. This report results from a Stage 2 - Preliminary Design Road Safety Audit carried out on the proposed Placement of New LED Advertising Sign at Bussell Highway Slk 0.43 - Bunbury Turf Club. The background and objective of the proposed project is to review the location of a proposed new LED sign and the impact with road users using Main Roads Policy for Advertising Signs required by the City of Bunbury. The Audit was undertaken by Bradley Brooksby of Brad Brooksby Consulting with reference to the details provided in the Audit Brief. The audit comprised an examination of the drawings and other information supplied by Alex Doble of the Bunbury Turf Club as listed in Appendix D. All the findings described in Section 2 of this report are considered by the audit team to require action in order to improve the safety of the proposed project and to minimise the risk of crash occurrence and reduce potential crash severity. The audit team has examined and reported only on the road safety implications of the project as presented and has not examined or verified the compliance of the design to any other criteria.

This is to be delivered through the Road Safety Audit process by accepting that people will always make mistakes and by considering the known limits to crash forces the human body can tolerate. This is to be achieved by focusing the Road Safety Audit on particular crash types that are known to result in higher severity outcomes at relatively lower speed environments to reduce the risk of fatal and serious injury crashes. The additional annotation “IMPORTANT” shall be used to provide emphasis to any road safety audit finding that has the potential to result in fatal or serious injury or findings that are likely to result in the following crash types above the related speed environment: head-on (>70 km/h), right angle (>50 km/h), run off road impact object (>40 km/h), and crashes involving vulnerable road users (>30 km/h), as these crash types are known to result in higher severity outcomes at relatively lower speed environments. The exposure and likelihood of crash occurrence shall then be considered for all findings deemed “IMPORTANT” and evaluated based on an auditor’s professional judgement. Auditors should consider factors such as traffic volumes and movements, TC2018.95 2 | Page Brad Brooksby Consulting speed environment, crash history and the road environment, and apply road safety engineering and crash investigation experience to determine the likelihood of crash occurrence. The likelihood of crash occurrence shall be considered either “VERY HIGH”, “HIGH”, “MODERATE” or “LOW” and this additional annotation shall be displayed following the “IMPORTANT” annotation on applicable findings. 1.5 Previous Safety Audits Nil. 1.6 Background Data 1.6.1 Crash History A study of the recent crash history has been conducted 200 m before and 200 m after the proposed sign location (Slk 0.23 - 0.64) for the five-year period to the end of December 2016. This showed that there were 5 reported crashes within the extracted data which is summarised below: 3 RUM 31 Rear end crashes with Property damage severity; and 2 RUM 32 Rear end crashes with Property damage severity. All the crashes were midblock and during daylight conditions. 1.6.2 Traffic and Speed Data A summary of recent traffic data is provided below: Vehicles per day Location Date Source (% heavy vehicles) Bussell Highway 22,105 No. 20450560 2013 Traffic Map (4.9 %) (Site 52184) A summary of recent speed data is provided below: Speed Zone 85th Location Average Percentile Date Source Speed (Km/h) Speed (Km/h) Bussell Highway 60 Km/h No. 20450560 64.8 Km/h 2013 Traffic Map 61.1 Km/h (Site 52184) TC2018.95 3 | Page Brad Brooksby Consulting Figure 1 - Traffic data from Main Roads Traffic Map 1.6.3 Road Details Bussell Highway is under the care and control of the City of Bunbury from Nuytsia Avenue (Slk 0.0) to Robertson Drive (Slk 1.38).
