To ask the Secretary of State for Transport what statistics his Department has collected on the use of average speed cameras and their effectiveness in reducing (a) accidents and (b) fatal accidents.
The Department for Transport does not collect statistics on the use of average speed cameras on local roads.
The most recent evaluation of the effectiveness of safety cameras was carried out in the four-year evaluation report of the National Safety Camera Programme, published in 2005. This evaluation did not, however, specifically address average speed reduction cameras.
In England, since the National Safety Camera Programme ceased in 2007, evaluation of safety cameras on local roads has been for the individual safety camera partnerships, local authorities and police forces which operate the cameras.
The Highways Agency produces Post Opening Project Evaluation (POPE) reports for average speed camera systems on the Highways Agency network in England.
