The 34-kilometre section of road between Bredbo and Cooma is one of 20 locations across the state to have the systems installed.

Point to point cameras target heavy vehicle users, with a gross vehicle mass of 4.5 tonnes or more. The cameras measure the amount of time it takes a heavy vehicle to drive between two points and then calculates the average speed of the vehicle.

Point to point camera locations are chosen based upon the frequency of heavy vehicle crashes, heavy vehicle speed and road conditions.

A spokesman for the RTA said the technology is aimed at slowing down speeding heavy vehicle users on a stretch of road with a history of heavy vehicle crashes.

“Statistics show from 2004 to 2008 there were three people killed and 21 injured along the stretch where the cameras will operate. Surveys found heavy vehicles were involved in two thirds of the fatal crashes,” he said.

“Studies of point-to-point enforcement conducted overseas have shown a 50 per cent drop in fatal and serious injury crashes after these cameras were installed,” the spokesman said.

Research conducted by the RTA found that while heavy vehicles make up only three per cent of vehicle registrations, they are involved in 20 per cent of road fatalities.

For heavy vehicle users who are caught speeding in the point to point area existing speeding laws will apply and an additional demerit point will be incurred.

“This is because offences detected by point-to-point enforcement demonstrate continued speeding over a long distance,” the RTA spokesman said.

The cameras are expected to be operational soon and will be clearly marked, with warning signs posted at the start and end of these lengths of roads. An initial warning letter period will apply before infringements are issued.
