I had occasion to take a journey driven by a former colleague on a cross
country route a while back. I was shocked that almost as a matter of
principle he drove at 38mph through villages where the speed limit was
30mph (which is too high anyway for residential environments IMO), his
reasoning being that there was a 10% allowance for incorrect
speedometers (notwithstanding that that might have worked in the other
direction) and then plus 5mph because "the police don't bother with less
than that". No wonder we need speed cameras when there is almost
institutionalised abuse, let alone Home Zones.
At least the rules governing 20mph areas (not specifically Home Zones)
have been relaxed a bit to make them easier to implement (though
Cambridgeshire is till very reluctant, places like Hull and Portsmouth
have been really progressive on this).
I think the approach off Earlham Road in Norwich (and I've seen it
elsewhere too) is quite interesting. The 20mph streets are signed with
the usual 20mph roundel, but have a plate underneath which is a
children's drawing all about slowing down (e.g. a snail). There's lots
of different ones. A nice piece of psychology I thought.
Cambourne in Cambridgeshire also has a different approach. They have a
19mph speed limit. I think the psychology here is to make you do a
double take on seeing the sign, because it is unusual. It's self
defeating of course if used widely.
The Home Zone would usually go further than a sign - the street would be
re-engineered to blur the distinction between road and pavement, to
integrate movements and parking and so on. There's a whole organisation
devoted to them:
see also the IHE website http://www.homezones.org.uk/
On the whole I think they're a good idea, but there is a downside that
it could make people think, at least subconsciously, that these are the
only residential streets where you have to take such extreme care.
Anyway, this is all rather off topic, sorry.
