The UK Home Office has approved the use of a new average speed camera system SPECS3, which allows a network of cameras to measure the average speed of vehicles.

The system allows a network of average speed cameras linked wirelessly through transmitters to monitor traffic for up to 15 miles on main roads.

The system measures the average speed of vehicles between camera locations and routinely sends number plate data back to a remote central server so that action can be taken.

The system can improve traffic flow, road safety and reliability as well as allowing vehicles to merge and diverge more easily, according to the developer Speed Check Services.

The system is planned to be installed in 20mph zones, rural routes, strategic trunk roads and Managed Motorway applications.

Camden, Southwark and Waltham Forest will be among the eight London Boroughs to begin installing the new system.
