The former head of the Roads and Traffic Authority's Road Safety Centre has defended a New South Wales Government decision to turn off a speed camera near the scene of a fatal north coast accident this week.
Two people, including an 11-year-old boy, died at Urunga on Sunday when a truck and utility crashed into a house.
Dr Soames Job says more speed cameras need to be installed across NSW.
However, he says switching off of the Urunga camera was justified.
"The data indicated that some cameras weren't giving us the road safety benefit we expected for various complex reasons," he said.
"There is a reasonableness to that.
"I think what is getting in the way is that there is a lot of media constantly saying that cameras are just for revenue, that speed cameras don't work, that speed cameras are inaccurate. All of those statements are false."
He says the Government should expand its point-to-point speed camera program, which he says is currently only used for trucks.
