The West Australian Government will consider changing road rules to improve the safety of cyclists but is still refusing to support a mandatory one-metre safety buffer.

The Greens and cycling groups want new laws to force motorists to maintain a one-metre gap when passing cyclists.

Premier Colin Barnett will meet with stakeholders to explore alternative ways to protect the growing number of cyclists.

"It has now become a form of organised exercise. That's a good thing," he said.

"But you have large groups of cyclists on the road. Now that's a new phenomenon, and we're going to have to look at road rules and road protocols to accommodate that."

Mr Barnett said the one-metre rule was not practical, but he planned to hold talks with cycling groups, police and the RAC to look at other ways of dealing with road safety concerns.

"It's been an issue over the summer and we need to look at safety for all road users and the sharing of the road," he said.

Road safety should be shared: Transport Minister

Transport Minister Dean Nalder said it was clear road safety was a shared responsibility.

"We definitely see that there is room for improvement on both sides, that we need to lift awareness for both drivers and for cyclists," he said.

He hoped to get additional funding to run a targeted awareness campaign on the issue.

Police Minister Liza Harvey said her office had been widely consulting with cycling groups.

"Minister Nalder and I have made a commitment to work together on this to ensure we can improve cyclist safety," she said.

"And a lot of that will involve an education program for cyclists and for motorists."

Ms Harvey said the data she had seen on serious cyclist accidents was worrying.

"The vast majority of cycling accidents where there's been a very serious injury appear to be the cyclist's error in contravening signals and contravening stop signs and those sorts of things," she said.

A spokesman for the Minster said an analysis of seven fatal cycling accidents in 2014 showed five appeared to be the fault of the cyclist.

Two resulted in charges being laid against motorists, he said.
