If it's common, where else does it happen? There is a pedestrian crossing
in Harrow which has phantom pedestrian phases, but apart from that, I've
never noticed it elsewhere.

Phantom pedestrian phases are often cause by the local scrotii jamming a
match in the button....

Hmm. No it should time out after a while and should send a constant input
alarm I think.

New crossings are button and beacon input - so you can push the button but
if nothing activates the sensor it should just 'wait' on calling the
pedestrian route till it gets an input then it will call it in the usual
way.

Junctions that go mad its often the Scoot loops broken/beacon, or something
in the chain broken and the controller is missing an input or another
action. Lights stuck on a phase usually send an alarm back after (I think
120 Sec on red)

Its also worth pointing out that a number (quite a lot) of junctions and
things are 'on-line' anyway feeding the Scoot data back to the GIS
application. The knock on of that is you can then 'control' the junction
(usually with defined configurations against time periods)

If you want to report the fault/problem then its TfL streets you want - and
they will either take the road junction details, or on the side of the
controller cab there is a number (XX/XXX) that's the site specific ID and
they will be quite happy with that too.
