From the Transport for London Web Site:
The new information tool identifies traffic hotspots and makes congestion easier to avoid.
By simply visiting tfl.gov.uk/trafficnews, motorists can now gain a bird’s eye view of London’s traffic hotspots to see where traffic is building up and which areas to avoid.
This includes access to a network of 170 ‘jam cams’, as well as information on incidents that may affect their journey.
A new Twitter stream @TfLTrafficNews is also available.
