Not far from me, there's a country lane about a mile long, connecting
two villages. Although it's a bit of a rat-run for commuters, it's
generally pretty quiet.

The local council recently spent (almost certainly) a small fortune
refurbishing, to a very high standard, a footpath along the full length
of the lane. It took them about six weeks. The work frequently
'required' the use of temporary traffic lights and, at one stage, the
complete closure of the road for several days.

I hadn't been along the lane for some time, but, when I went that way
today, I was surprised to find that, half way along, where the footpath
crosses from one side of the lane to the other, they have also installed
a pedestrian crossing with traffic lights!

Which bit relates to 'eliminated serious casualties'?

None of it - sorry, it's one of the few reports that I have bookmarked
that don't directly support that - here's a couple of others
to make up for that:

<http://is.gd/e0TTr>
"There have been no serious accidents in Drachten since
installation of the new intersection in February 2004,
whereas between 1998 and 2002, when it was still an
intersection with traffic lights, signs and lanes,
eight accidents were registered, five of which involved
injuries."

<http://is.gd/e0Uyv>
"[of Norrköpping]... since the redevelopment there have
been no accidents, mean traffic speeds of 16 to 21
kilometres per hour,hour, road users have become quite
satisfied and road safety and liveability increased."

<http://is.gd/e0VYL>
"[of Ashford]... 'There were no notified incidents and
accidents and no personal injuries reported.'

'We had a three to four lane one way system that was
difficult for people to cross and which we had real
problems with speeding.'

'Speeds have more than halved on average. Previously
we had an average of well above 40mph. Now it is far
less than 25mph.'"

18 months of 'no serious' vs 5 years with '5 minor' ?

How many before?

How many before?

(You will appreciate that we have about 20,000 serious casualties a year on
80,000 miles of urban roads, so 'no serious injuries in 4 years at a
junction' is not a significant change).

Oh, and that is presumably 'within 20 metres of a junction'.

How far apart do you estimate junctions are in built-up areas?
