A proposed system of charging motorists for the distances they travel is to be tried out in a British city next year.
Dozens of drivers in Leeds will be testing alternatives to road tax and fuel duty.
Transport Secretary Alastair Darling has said a major shift in policy is needed to cut congestion.
He is considering replacing fuel duty with a new road pricing scheme dependent on the journey distance.
"You could dance around this for years but every year the problem is getting worse," said Mr Darling.
"We have got to do everything we can during the course of this Parliament to decide whether or not we go with road pricing."
On current estimates, that could be as much as £1.34 a mile on the most popular routes but as little as 2p a mile on quiet rural roads.
In Leeds, 450 volunteers will be involved in a trial of three different systems next year.
One is a simple congestion charge where a camera network monitors vehicles entering a certain area.
The other two systems are more sophisticated and would involved drivers paying for every mile they travel.
One uses global positioning system technology, with satellites "talking to" small electronic boxes under car bonnets.
The third system uses microwave technology to produce a similar effect.
