NEWS London is set to begin a £2.2m trial of road toll-style smart card charging technology that could be extended as an enforcement tool in the congestion charging zone.
The system involves tags or smart cards being fitted to vehicles and monitored by roadside readers – or 'beacons' – at various points around the charging zone. The readings will be used to measure journeys and calculate the correct toll or Congestion Charge.
Transport for London (TfL) will begin a small-scale "tag and beacon" trial in part of the congestion charging zone of different technologies that can be used in conjunction with the existing automatic number plate recognition method.
TfL is looking to develop what it calls a "free-flow" charging scheme for vehicles in London but has ruled out use of the large overhead gantries typically seen in toll plazas for "practical and aesthetic" reasons.
Instead it wants to place more discreet 'beacons' at various roadside points that will monitor the tags in vehicles using dedicated short range communication technology and verify the class of vehicle for charging purposes.
Earlier this year the government outlined plans for a national satellite-based road-charging scheme that would charge motorists up to £1.30 a mile. TfL looked at the possibility of using satellite navigation technology for London road pricing but said its own trials found that affordable satellite systems will not be feasible for "at least a decade".
The trial is expected to last for around six months and could cost up to £2.2m. A spokeswoman for TfL told silicon.com it will be used in a small part of the current congestion charging zone and wider deployment will be dependent upon the results of the trial.

So there are still engineers out there that have never grasped the principles of electromagnetic interference?
GPS is easily disrupted by un-supressed ignition noise, short range digital communication suffers in the same way.
It will only be when these techies get out of their development environments that the scheme will be de-railed and by then a lot of money will have been wasted.

No.No.No. The British motorist is amongst the highest taxed in europe and least provided with roads.
Road charges are simply a lucrative form of additional taxation that will mainly unfairly hit the less well off.
The answer to congestion problems is a modest strategic road building programme. Only one percent of land is used for roads so there is no substance in the argument that the country will be covered in concrete.
