Should vehicle excise duty and fuel duty be replaced by a distance-travelled tax on motorists - paid in proportion to the distance people drive each year?

The idea has won the annual Wolfson Economics Prize which this year asked people to come up with a plan to help fund better, safer, more reliable roads in a way that is fair to road users and good for the economy and the environment.

It is a classic question over whether we should have user-based charges (or taxes) for road vehicles and which system is both equitable and efficient?

Gergely Raccuja - a 27 year old graduate from UCL and a transport planner - is the winner of the prize and his proposals are discussed here on the BBC news website. Find out more about "Miles Better: by clicking on the tweet below from the Wolfson Prize.
