Trials of numberplate recognition cameras and screens which flash up a cars numberplate and a warning have shown that such a name and shame scheme for speeding drivers reduces speed more effectively than penalty-issuing cameras. A trial on the M42 near Birmingham found that this was most effective through roadworks where a temporary 50mph limit had been posted, increasing the safety of road-workers.
The Department of Transport found that speeding on this stretch was much-reduced with half of all cars travelling at over 55mph slowing to, or close to, the 50mph limit, and two-thirds of those going over 60mph slowing. This compares to a reduction in speeding of just 31percent where cameras have been installed, with the additional benefit that drivers tended to remain at a lower speed after passing the flashing screens, instead of speeding up again.
The Highways Agency has now indicated that it will replace cameras at motorway roadworks - which usually generate thousands of pounds-worth of revenue in penalty notices - with speed warning screens, which are also cheaper and easier to install. Though fines will not be issued to drivers exceeding the speed limit, a database of offenders will be kept, and persistent speeders may be sent a warning notice. (The Times)
