Notorious Bow Roundabout gets low level signals for cyclists
The UK's first low level traffic signals have been put into operation at Bow Roundabout.
The notorious junction has been the scene of three cyclist fatalities in recent years and transport chiefs say the lights will give those on bikes a head-start on traffic.
Transport for London said more than 80 per cent of cyclists favoured the use of low-level signals.
Another 11 sites around the capital will also see trials of the technology, which is already in use across parts of Europe.
British Cycling's campaigns manager, Martin Key, said: "They make it easier for cyclists to know when it is safe for them to ride through the junction.
"These lights and other cycle friendly measures should be available to use not only in London but across the whole country over the next couple of years."
Mayor of London, Boris Johnson, said: "Innovative measures such as this are just one of a number of new safety initiatives we've been pushing for as part of my vision for cycling."
Other plans for the road leading up the Bow Roundabout will see "cycle-separated junctions" and "full or semi segregation" installed on parts of the route known as Cycle Superhighway 2.
The roundabout was heavily criticised over the deaths of 58-year-old Brian Dorling and Svitlana Tereschenko, 34, in 2011, and 24-year-old Venera Minakhmetova last October.
