Speed cameras and other traffic calming measures are contributing to serious accidents according to new research due out next month. The news comes on the back of a major Home Office annoucement that their number is set to dramatically increase in the coming months.

The report by the Newcastle based Transport Research Group (TRG) entitled 'Dangers of Safety', will say that inappropriately positioned speed cameras and chicanes were key factors in three fatal accidents in London and two in

Newcastle-Upon-Tyne. While refusing to give details of the incidents involved, a spokesman for TRG claimed that research had shown that speed cameras could cause sudden responses from drivers, resulting in loss of control of their vehicles.

A spokesman for the Metropolitan Police said, "Camera positions are specifically chosen so as to reduce the risk of accidents. All our experience to date has shown them to be remarkably successful in achieving this objective."
