WIRE ROPE SAFETY BARRIERS

In reply to the Hon. J.S.L. DAWKINS (23 September 2008).

The Hon. CARMEL ZOLLO (Minister for Correctional Services, Minister for Road Safety, Minister for Gambling, Minister Assisting the Minister for Multicultural Affairs): I am advised:

Centre line audio tactile line marking (ATLM) has not been used in South Australia but is being investigated and monitored closely in other states. The typical installation cost of the ATLM is approximately $3.60 per metre ($3,600 per kilometre) in the centre line situation. ATLM is designed as a fatigue countermeasure and alerts the driver, through an audio and vibration effect, when they deviate from their lane. It is not an alternative to safety barrier treatment.
