National Road Pricing is technically feasible. If we started with just the motorway network where over 20% [15] of total vehicle miles are driven, it has been estimated that there are approximately 800 motorway intersections and junctions. This could require of the order of 1,600-2,000 camera sites, depending on where they are located and the configuration of slip roads, to measure distance driven and detect entry and exit location. This is only ten times the scale of the London scheme in terms of vehicle detection sites. Regarding customer payment channels, there is now much greater take up of digital channels than in 2003, so payment facilities for the occasional user as well as regular users should be much easier to implement at lower unit cost per transaction. Given the better quality of DVLA's registration data and greater opportunity to have account based payment, it should also be easier to accurately bill UK drivers for their usage and enforce against non-payers. We conclude that a national scheme is eminently feasible for the United Kingdom.
