HC Deb 11 February 1998 vol 306 c212W
Mr. Llwyd

To ask the Secretary of State for the Home Department how many prosecutions have resulted from the installation of speed cameras in the Dyfed Powys Police area; and what estimate he has made of their effect on the number of accidents on the roads concerned. [27974]

Mr. Michael

Information available centrally shows that ten prosecutions resulted from the use of automatic speed cameras in the Dyfed Powys Police area in 1995 and 38 in 1996. Information is not available centrally to show how many prosecutions may have occurred from the use of other speed enforcement devices of a portable nature.

I understand from the Chief Constable of Dyfed Powys that the Force targeted roads on which excessive speeds were known to occur rather than accident black spots. There is therefore no information available on the impact of the use of these cameras on local accident statistics in Dyfed Powys. However, I can refer the hon. Member to the evaluation of the effectiveness of automatic speed and traffic light cameras in reducing traffic casualties which we published in 1996. ("Cost benefit analysis of traffic light and speed cameras"). A copy is in the Library.
