M5: Cameras

Volume 501: debated on Wednesday 25 November 2009

To ask the Minister of State, Department for Transport what the purpose is of fixed cameras on the M5 motorway. (300573)

[holding answer 24 November 2009]: On the M5 motorway the Highways Agency has three types of fixed camera in use.

CCTV Cameras allow real-time traffic conditions to be monitored by the Highways Agency's National and Regional Traffic Control Centres, enabling an efficient response to be made to incidents. The cameras also feed traffic information to a variety of information and media services for drivers to plan their journeys.

Automatic number plate recognition (ANPR) cameras link to a system which converts and anonymises number plates to ‘tag' codes for each passing vehicle at each camera location. The ‘tag' codes are then used to calculate traffic flows and speed between camera locations in order to inform our understanding of network performance.

Average speed cameras are positioned temporarily at major roadwork sites to improve safety for road users and the workforce on the motorway. The cameras monitor vehicle speed between two points and check the average speed compliance with the speed limit.
