"The test runs will start early next year in four locations and will involve fitting a satellite-tracking device to the vehicles of volunteers. An on-board unit will automatically deduct payments from a shadow account set up in the driver's name."
"Paul Clark, the Transport Minister, confirmed yesterday that the trials would proceed despite previous statements from the Government suggesting that it had abandoned the idea of a national road-pricing scheme. In 2004 a feasibility study considered a range of possible prices, up to £1.30 a mile. It said that the highest rate 'would be paid by only 0.5 per cent of traffic'."
"The on-board unit could be used to collect all road charges, such as congestion charges in London and Manchester and tolls for crossing bridges and using new lanes on motorways."
