More than 1, 000 cyclists and drivers staged what they've called a 'die-in' tonight.
Guide for cyclists and motorists from Transport for London
The Mayor of London says lorries need to be made safer for cyclists so that more people will turn to pedal power.
Former Olympic cycling champion Chris Boardman says MPs investigating cycling safety should be "embarrassed by their performance" during their Select Committee hearing.
Chris Boardman is British Cycling's policy adviser and claims MPs on the House of Commons Transport Committee showed they "didn't even know the most basic of facts".
The committee is taking evidence following the spate of cyclist accidents which led to the deaths of six cyclists in London during a two-week period last month.
Tonight, more than 1, 000 cyclists and drivers lay sprawled across the road outside Transport for London's headquarters, at a protest against dangerous traffic conditions. London Mayor Boris Johnson praised them for drawing attention to road safety in the capital. He said:

"This targeted operation has been hugely effective at raising awareness of road safety among motorists and cyclists.
"This is a balanced operation reminding everyone of their duty to take care of each other while out on the roads, and I hope the figures put to rest concerns by some groups that they are being singled out."
More than 1,000 cyclists lay sprawled across a Southwark road this evening in a protest against dangerous traffic conditions. Dubbed a "die-in", protesters blocked roads outside the Transport for London headquarters as part of a vigil for six cyclists killed in the capital this month.
The demonstration saw riders spread across Blackfriars Road with their bikes strewn around them, while others held candles in tribute to the latest spate of casualties.

Cyclists are holding a vigil and mass "die-in", as part of a protest against the recent spate of cycling deaths on London roads.
The organisers said lorry drivers and motorists were also welcome at the protest in Blackfriars Road.
Hundreds of cyclists have gathered outside the headquarters of Transport for London calling for safer streets for cyclists. The Stop The Killing of Cyclists demonstration has closed Blackfriars Road, in Southwark.
A cyclist has been taken to hospital after being hit by a lorry on the Warwick Gardens junction near Kensington High Road, the London Ambulance Service said today.
The women, believed to be in her 40s, sustained injuries not thought to be life-threatening.
Cycling Minister Robert Goodwill has urged cyclists to position themselves positively on the roads and make sure vehicle drivers know their intentions. Mr Goodwill cycled around the capital today, finding:
I didn't feel in danger at any time - I do cycle in London but I think if I was a London cycling virgin I would have been a little bit nervous, possibly.
When we came out of Kings Cross, we got on to some quite good segregated routes, some quiet routes I didn't even know existed. We went down Royal College Street where they have spent a lot of money... I thought that was fine and I felt safe.
There was a bizarre one in Southwark where I went across the road and there was a cycle lane coming the other way, but the cycle lane on our side started three metres later and then it was on a footpath.
The Cycling Minister said today he saw both very good and very bad infrastructure on a ride around the capital but denied he felt in danger at any time.
Robert Goodwill spent an hour cycling around London, from Kings Cross to Westminster via Camden, Southwark and Lambeth.
But Mr Goodwill criticised confusing road markings and bike lanes in Southwark, after venturing south of the Thames on his Brompton folding bicycle, joined by Department for Transport aides.
