Dunno what or where "Brompton" is, but if it's around Brompton Cross SW3
then those lights are managed by the borough (RBK&C) which opposes the
extension and has no incentive to exaggerate the success of the scheme.

I wonder if the RBK&C employee responsible (or in fact the whole
department) are Ken's fans, an awful lot of sandal wearing lentil
munchers are and as we all know because they can't survive in the real
world they gravitate to these type of jobs, they could easily support
Ken's subterfuge without seeming to be biased.

seconds of your light being green, then you have to wait a FULL THREE
MINUTES for the light to go green again!" (do the math, as our American
cousins say).

That's an interesting conundrum, given so many roads. If the lights
change too often, a high proportion of the green phase is soaked up by
people daydreaming before they realise the lights have turned green. If
you make the green phase longer, it takes proportionately longer for
one's turn to come round again. So the more efficient process is
subjectively worse, and may even lead to people jumping the lights in
frustration.

I'm reminded about an old study on computer interaction: if people have
to wait for output to appear, it seems slow; if it comes steadily, it
seems faster. To the extent that a /slow/ system with continuous output
is preferred to a /fast/ system where you have to wait before anything
happens.

Brompton is an area in SW London fairly near to Chelsea.

There's an oratory, a cemetery and a road all called Brompton, but I've
never heard anyone refer to an area called Brompton, and I've lived in
south London for over 50 years.

Would the solution be a roundabout?

I don't know the junction, so this may be a rubbish suggestion. Seems
to work adequately for the only seven road junction I know.

Looking at the map
(http://www.streetmap.co.uk/streetmap...80360&A=Y&Z=1),
it's pretty nightmarish. I don't go there often by car (certainly never
driven there myself!), so hard to remember what the exact layout is on
the ground. Pall Mall, Haymarket, Charing X Road, Strand, Northumberland
Ave, Whitehall and The Mall (all the well-known names!) all converge on
this tiny piece of land; and they're all (usually) busy. If you don't
know beforehand which lane to use next, you're in trouble.

And major changes are probably politically impossible for such a
well-known place.

Yes, the Extension will start on 19 February 2007, but the claim was made
that someone was tampering with lights in order to create congestion prior

I think I'll just stay in West Cumbria, where a traffic jam is six cars
waiting for the lights to go green.

Brompton isn't in South London.

...if you do, remember that not all the seven routes feed traffic into the
square.

The ones that do:

The Strand
Northumberland Avenue (which gets a green phase of about 10 seconds per
cycle - no more)
Whitehall
Admiralty Arch/The Mall
Cockspur Street
St Martins Place/Charing Cross Road

The one that effectively doesn't (any more):

Pall Mall East (because it is now just a loop from Cockspur Street and no
longer gives an advantage for north- or east-bound traffic)

The one that doesn't:

Duncannon Street.

Since the main traffic function of Trafalgar Square is now that of a
roundabout on the south side of the square, there isn't any need at all for
traffic lights at that side. But that would never do; it would lead to
efficiency.

Impossible? Ken has just spent millions changing it from the roundabout
it was by paving over the road in front of the National Gallery.

Have you read Vanity Fair? IIRC Amelia Sedley's parents have a cottage
"in the country" at Brompton, to which she retires after George Osborne
dies.

Patrick

Even at the time of the Battle of Waterloo, Brompton/Knightsbridge would
probably have not been described as "in the country". There are several
"Bromptons" in southern England, including one in Kent which was familiar
to Dickens.
