Parking ticket fines will rise by �10

And that demand is supported by Neil Greig of the AA in Scotland.

"We would like to see them taking this money and putting it into more camera enforcement and more traffic calming in the right places - actually feeding back some money into road safety and bringing down the number of people killed on the roads," he said.

"Fines themselves just don't work."

City of Edinburgh Council has hosted a seminar on congestion charging - an idea which could force those heading for the centre of the capital to pay �2 for the privilege.

"Every single penny raised will be invested back into transport infrastructure - people would see the money going back into improved transport," said Councillor Mark Lazarowicz.

Speeding figures

However, the idea is still some way off - not least because of the technology which would be required.

According to government figures, speeding contributes to about a third of all road accidents in the UK.

Last year 3,423 people were killed on the roads and 39,122 seriously injured.

Home Office minister Charles Clarke said the figures were "unacceptable".
