Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to her Department's guidance entitled Using speed and red-light cameras for traffic enforcement: deployment, visibility and signing, published on 31 January 2007, what recent assessment her Department has made of the effectiveness of the criteria for the placement of fixed speed cameras in reducing (a) speeding and (b) road accidents.

The Department for Transport has not made a recent assessment of the effectiveness of the criteria for the placement of fixed speed cameras in reducing (a) speeding and (b) road collisions. While the speed camera guidance does include criteria for placement which the police and traffic authorities may consider using, it invites authorities to set their own criteria, depending on local needs and priorities.

The guidance notes that while the primary objective for camera deployment is to reduce the number of deaths and serious injuries, cameras can also be beneficial where there is community concern. The guidance is not mandatory; there are no Department for Transport rules preventing traffic authorities from installing speed cameras.

To note, my Department uses the terms 'collision' or 'crash' rather than 'accident'.
