Concerned Chelsea residents have branded the removal of Holbein Place traffic signals at the new road crossing outside Sloane Square underground station an "accident waiting to happen".
Holbein Place was opened a fortnight ago after the completion of work to level-off the road and pavement to create a 'shared space' scheme to encourage drivers to give way to pedestrians and prevent bottle-necks at narrow traffic crossings.
But it has sparked fears pedestrians will absent-mindedly walk out from the station and into oncoming cars thinking they are on a safe paved area.
Gordon Taylor, chair of the West London Residents' Association, says the crossing is endangering lives as neither cars nor pedestrians are sure who has right of way.
"People are walking out into the road oblivious to the cars. The assumption is that a paved level area outside a tube station is safe for pedestrians, when clearly it is not if cars are still haring round Slaone Square towards the crossing."
Mr Taylor is calling on Kensington and Chelsea council to urgently review the 'shared space' scheme, as it is known, and re-instate traffic signals before an accident occurs.
He has been joined by another local campaigner Justin Downes, of Hans Place, who says the shared space concept is "completely inappropriate" for the busy central London road.
"This is an idea imported from small European cities, where it is an attractive idea to regulate the flow of people, cylcists and cars. But this is London and there are far too many cars and people crossing at the same time for it to be safe," he said.
The Town Hall says the concept was introduced to stop people dashing out across the Holbein Place crossing during red lights.
A council spokeswoman said: "The removal of the signals and the single surface treatment encourages drivers to exercise cuation and give way to pedestrians. This type of crossing is not untried or untested and there is no evidence to show they are unsafe."
Temporary signs warning pedestrians and drivers of the new crossing have been put in place, and council road safety officers are monitoring the crossing. A 'safety audit' will also be carried out in the New Year, the spokeswoman added.
