How do you know they're on green at the moment?

May I butt in with a simple Carriageways vs lanes statement? (clearly
someone should reply with a 'no' here).

The numbers of 'lanes' on a road and number of 'carriageways' have nothing
to do with each other. The word carriageway refers to a stretch of tarmac. A
single stretch of tarmac is a single carriageway and can have 1, 2, 3, 4+
lanes painted upon it and those lanes can run in either direction. If there
are 2 separate pieces of tarmac with a divider (gravel trap or grassy strip)
between them, then we have two carriageways (commonly called dual
carriageway). Each of these 2 carriageways can have 1, 2, 3+ lanes painted
on them, but traffic usually flows in only one direction per carriageway.

Having said this, I'm not sure if the national 60 limit increases to 70
*automatically* as soon as the central reservation appears. I seem to
remember that there has to be a 'dual carriageway' sign before the limit
actually goes up to 70, despite the fact that the driver can clearly see
that the carriageway has split in two.

As posted already, in some cities, the lights are timed to increase traffic
flow - as one set of lights changes to green the traffic accellerates up to
the speed limit and the lights down the road are timed so that as the
traffic arrives at the speed limit, the lights change to green. Of course,
if there is a slow moving vehicle holding everyone up and illegally refusing
to yield, then this system falls down around its feet!

I also read that lots of these timings were changed a few months before
London brought in congestion charging - this was to falsly increase the
congestion and then after the congestion charging was introduced, they put
the timings back and claimed that congestion charging was a winner!

I wonder why they bother with the 60/70 difference. A head on with a closing
speed of 120 isn't going to be any more survivable than one at 140.
