Now, the diagonal at Oxford Circus is actually quite a long way. I
assume
the phasing allows plenty of time for the slowest pedestrian to cross
the
diagonal which is going to leave an awuful lot of time on red when
people
are going to be tempted to cross. I really wouldn't want to get
trapped in
the middle with traffic all around me, yet that is exactly what was
close
to happening to people on Saturday.

In the US there can be a countdown number as well so you can see
exactly how long you have. Tfl is going to try this in London.
