London is set to get average speed cameras to help to enforce a 20mph speed limit in residential areas.
Eight London boroughs including Camden, Southwark and Waltham Forest are all set to pioneer the cameras which will be connected wirelessly to monitor drivers speeds over a distance.
The Department for Transport believes that the cameras will improve safety in the areas for both pedestrians and other road users. Currently, average speed cameras are commonly found at accident blackspots and on motorways.
Portsmouth has already enforced a 20mph limit in its residential areas, with Norwich and York also to follow suit.
