The Alliance of British Drivers have published a press release on the latest evidence concerning the effectiveness of speed cameras. See this link for more information: https://twitter.com/TheABD/status/703714480400830465/photo/1
It highlights analyses of the claims for speed camera benefits in London, the Thames Valley and Wales which contradict the claims made for their effectiveness. There are also doubts about their use in Scotland and a wider scale study by Idris Francis, a well known campaigner against cameras, is about to be published.
Here is a brief extract from the press release giving the comments of the ABD: “The response of the authorities and other vested interests to soundly-based criticisms that their claims were clearly nonsense has certainly been consistent. Since the first official reports from 2002 onwards, they have sought to bury their heads in the sand – in the hope that the damning and mounting evidence that cameras are useless for road safety purposes will simply go away. Given how very lucrative are speed cameras and their downstream operations; it is hardly surprising that Camera Partnerships and other financially-involved, vested interest groups continue to systematically and cynically misrepresent the reporting of casualty data trends and the effects on them of speed cameras. The emerging evidence clearly shows that speed cameras are nothing less than a monumental waste of a very great deal of money – that ought to be put to better use elsewhere on: e.g., road and junction improvements, dualling etc.”
Those who promote the benefits of speed cameras, and continue to advocate more expenditure on them, as has happened in London of late, should surely study this data more carefully. Regrettably those who make decisions on these matters often seen to have closed minds and have little background in the science required to make sense of the data.
