The Victorian Government, for one, has set itself a five-year goal of reducing road deaths to 200 or below by 2020.
In its Towards Zero 2016/2020 Road Safety Strategy and Action Plan, the state government has outlined some major steps in how it aims to achieve its immediate goal through a ‘safe system’ approach.
Safety barriers, specifically linear flexible wire rope ones, are to be installed on roadsides and median strips and will play an important role in accomplishing that goal.
“The Victorian Government plans to install over 1700 kilometres of wire rope barriers on just about every major arterial road and highway in the state over the next two years. It’s an enormous project and one of the largest ever for the state,” says Bruce Grey, Australian Construction Product’s (ACP) Victoria, Tasmania and South Australia Sales Manager.
Mr. Grey says wire rope barriers have the most forgiving dynamic deflection, which makes them ideal for the application the Victorian Government is using them for. “The impact of severity on drivers is significantly less and provides better outcomes,” he adds.
ACP’s Sentryline II WRSB and non-release anchor system has been selected as one of the preferred barrier setups for the safety project.
Mr. Grey says the Sentryline four-wire rope barrier system has been on the market for over 10 years and gradually updated over that time. ACP introduced the Sentryline non-release Terminal End component in the past year to cater to the needs of road authorities.
When installed correctly, the system will allow an errant vehicle to over-ride or gate through the high tensioned anchor area of the terminal end.
Even if the terminal end is compromised, the non-release anchor provides a level of support for the short-term, thus lessening the need for maintenance and repair to be undertaken immediately.
A major advantage the Sentryline system has over other wire rope barrier products on the market is its length of need (LON), which is just eight metres from the non-release ground anchor (from the fifth post).
“The LON of the terminal is about 35 per cent less than other wire rope barriers on the market and it has superior dynamic deflection,” says Mr. Grey.
With the reduced terminal length, combined with minimal barrier components, assembly and installation is significantly easier, as is maintenance and repair.
“It’s a lot less complicated to put together which gives contractors the ability to reduce the time it takes to complete a project,” says Mr. Grey.
He adds that the capabilities of the Sentryline barrier system have been proved around Australia and he anticipates it will help make a significant impact on the safety of Victoria’s road network.
“The Sentryline is represented in every state and we look to put down a couple of hundred kilometres in Victoria in the next six months.”
