A witness to a dramatic crash at Minimax junction last month has claimed more accidents are inevitable unless urgent improvements are made.
From outside his premises in Staines Road Paul Woolgar has a near-perfect view of the junction between Staines Road and Harlington Road West.
And, although the recent tragedy was actually caused by a driver suffering a heart attack, the cafe owner insists dozens more accidents are occurring everyyear as a result of problems with the lights and road markings.
"I see an accident of some kind pretty much every week," said Mr Woolgar, from Hanworth.
"Mostly just little bumps but I've seen plenty of more serious crashes in the twoyears I've owned this place.
"Earlier this year an Astra was hit from the side so hard it ended up on top of the railings. It's just not safe.'
The junction is owned by Transport for London (TfL) and its figures show in the three years ending December 2007 there were 14 collisions, resulting in two serious injury casualties.
But as motorists are not obliged to report crashes unless someone is injured comprehensive figures do not exist for the total number of accidents at the site.
Mr Woolgar is convinced motorists regularly get into difficulties at the junction because of a combination of impatience, poor road markings and problems with the timing of the lights.
"If everyone did exactly what they should then there wouldn't be a problem," he added, "But that's not the world we live in. Drivers get very impatient along here and the markings are confusing and faded which doesn't help. It's only a matter of time before somebody is seriously hurt or killed."
Feltham councillor Mark Bowen said a pedestrian had contacted him to discuss their concerns about the crossings at the junction but he was not aware of a particular issue with traffic accidents.
A TfL spokeswoman said: "This junction had the signal timings revised in August 2007 to give more time to right-turning traffic. It is included in this year's London Road Safety programme to check the benefits of the changes and to investigate the potential benefits of additional road markings."
