Congestion Detection

Transport for London (TfL) is revolutionising the way it manages congestion on the Capital's roads with intelligent traffic cameras. Twenty cameras have been fitted with special image recognition technology at traffic hot spots across the city. The cameras can automatically spot and alert TfL's traffic control centre if congestion builds up. This enables operators to deal with incidents much faster. The new cameras allow operators to focus their efforts on dealing with congestion rather than having to search through all of London's traffic cameras looking for jams.
The 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.'
The technology has been developed by TfL's technical experts in partnership with Ipsotek Ltd.
Operators receive between six and 10 alerts each day - around 80 per cent of these are verified as genuine congestion problems. During February this year, 64 congestion incidents were picked up via the alerts before either operators, police or members of the public were able to flag them up. The cameras have been positioned at junctions where it is known that congestion, from even minor incidents such as a broken down vehicle, can build up and have a significant impact on traffic.
Information received from the cameras has also been put to wider use. The recurring congestion detected in Surrey Quays resulted in new permanent traffic plans with improved signal timings. These resulted in less alerts and smoother traffic conditions in the area.
