David,
Thanks for helping to put many of these issues into context. I was going
to mention the way the Australians use red arrows - in the opposite sense
to the way we use filter arrows (i.e. they stop right-turners using an
amber arrow then a red arrow - after which they drop the red arrow off!),
but I thought we were probably still 2 decades away from that in UK!
Not sure about your comment about staggered crossings - we certainly don't
put them in for any 'see through' reasons at junctions - we put them in
largely for efficiency reasons (as a form of parallel peds they help
minimise the dreaded congestion!). I think that Birmingham have recently
'outlawed' all-round peds in favour of staggered crossings on the basis of
congestion - care to comment Paul?
I know staggers are not popular with 'planners', but I really do believe
they can be more meaningful to pedestrians - in the sense that for each
crossing arm they can be more often faced with a clear-cut situation -
there's either 'traffic' or there's a 'green man'. I know things are never
that perfect, but contrast this with an (inefficient) all-red stage which
has a red man up for so much of the cycle (including the inevitable period
to protect peds against non-existent left turners) that the red man signal
can become meaningless.
