Safe System Audits (SSAs)
Making Projects Safer From Day One
A Safe System Audit (SSA) is an independent review of a road project or design, ensuring safety risks are identified and addressed early. Previously known as road safety audits, SSAs take a broader view - considering people, vehicles, speed, and infrastructure together.
Corridor Solutions delivers SSAs that are thorough, practical, and trusted by councils and contractors across Taupō, Rotorua, and the wider North Island.
What does a safe system audit look at on a real project?
Whether anything in the design could lead to a death or serious injury, for every person using the road, at the speeds they will travel. For the Waimahana Marae papakāinga development beside State Highway 5, our independent Safe System Audit of the new intersection design recommended safety improvements tailored to marae access and cultural traffic flows, and those improvements went straight into the intersection planning. Our audits are led by Ashley Green, a Lead Safe System Auditor who has investigated more than 50 fatal and serious crashes. Catching a problem on paper at concept or design stage costs far less than fixing it after construction, which is why we encourage developers to book the audit early. You can read more in our Waimahana Marae case study.
