Changing road rules to allow cyclists to go through red lights will probably increase the risks for people on bikes and is unlikely to be approved, Bicycle Network Victoria has said.

The idea was among some 11,000 responses to an online VicRoads survey of pedestrians, motorists and bike riders about how to make cycling more attractive.

Under the current road rules cyclists must stop at red lights or risk being fined.

Garry Brennan from Bicycle Network Victoria said it was highly unlikely that the proposal would be approved.

"We know from statistics that intersections are high-risk locations for people on bikes," he told 774 ABC Melbourne.

"Having a relaxation of the red-light rule would probably increase the risk for bike riders.

"In highly built-up cities like Melbourne with so many pedestrians on the street, it's probably not going to work for everyone to have some road users given permission to go through red lights."

One cyclist on St Kilda Road told 774 ABC Melbourne that he supported the idea but only in certain circumstances.

"I'm all about respecting all road users and I do adhere to red lights and traffic signals," he said.

"I think in some circumstances if there is a left hand turn where it is safe to do so, I think it's fair for all road users to use it."

James Holgate, the director of vehicle and road use and policy at VicRoads, said they wanted to encourage a mutual understanding about the road rules.

"What we're trying do is look at how do we make cycling safer, how to encourage more cycling and how do we improve all road users' mutual understanding and respect for the rights and obligations of cyclists," he said.

Mr Holgate said because the survey response was so large it would take some time to work through the results.

He said he was hopeful of having some results by the end of the year.

"We may decide we should improved some communication of the road rules.. or we may then work towards some changes to the road rules themselves," he said.

"The data will be useful information for us for probably many years to come."
