Using toll roads around Sydney could soon be a thing of the past, with calls for a fee per kilometre travelled in peak hour.
A leading transport economist has suggested drivers be charged five cents each kilometre when using Sydney roads at peak times, rather than spend money on tolls.
Professor David Hensher from the University of Sydney also suggested halving the cost of rego so Sydney drivers aren't paying any extra than they are presently.
It is also argued that drivers would be encouraged to use roads off-peak, which would have an impact on the rush hour traffic problem around the metropolitan area.
"The public will accept the scheme if it can be demonstrated that they are not financially worse off but they get a time saving," Professor Hensher said.
