Transport for London has installed a new network of 20 cameras at traffic hotspots that can automatically detect jams and alert controllers.

Commenting on the new system Mayor of London, Boris Johnson, said: “These cameras have a really important role to play in keeping London moving.

“The chaps in TfL’s control centre have a monster of a job scanning through the cameras looking for accidents or incidents that will slow traffic.

“So having cameras that can actually spot when traffic builds up and let the operators know is massively helpful and means they can get people moving again far quicker.”
