Lights blue touchpaper. Stands well back.

I saw this on the C+ forum.
http://www.tfl.gov.uk/cycles/company/standards.shtml


Quick browse...
4.1.4 "Cyclists expect to have the same priority as general traffic
moving in the same direction. Cycle lanes or tracks should not be
introduced where they result in disbenefits to cyclists such as
a loss of priority or time penalties. TfL research confirms such
facilities remain unused and the investment has been wasted."

We shall have a small break whilst smelling salts are adminstered to
some of our more exciteable correspondents.
Such outbreaks of clue do not happen every day.

Indeed not, but it's the second such outbreak I've come across in as
many days...

I posted previously (some months ago, in fact) about a strip of red
tarmac that was installed along a pavement in Canterbury, positioned
carefully so that it had a line of lamp-posts running all the way along
the middle of it.

I was passing by the same area yesterday and noticed that the
lamp-posts had been moved so they were no longer obstructing the path.
I don't know when they actually did this - I haven't been round that
part of town for a while - but I was very pleasantly surprised.

I've downloaded it, and in spite of having 20 pages of comment on my
web site about the previous edition, I'm having trouble getting
interested enough to read this edition.

I haven't found any mention of "Cycle-friendly Infrastructure",
which is about to be replaced by an entirely different
"Cycle-friendly Infrastructure". Section 1.5.8 says that there are
no such things as national design standards. The USA has had
standards for more than a quarter of a century, and Britain first
tried to write some in, I think,1978. I wonder what went wrong.

1.4.8 talks about sections of the London cycle network (LCN) "of
variable standard". I have many complaints about the LCN, but its
having a "variable standard" is the one complaint I have never made,
nor heard anyone else make. The standard is remarkably consistent.
Not only are the 34 authorities within London consistent, the whole
country is consistent.

The idea of courier bike routes (1.4.12) is interesting, even
somewhat mind boggling

There's the usual picture of a cyclist with a box round him, showing
how much room he needs. As usual, the authors seem unaware that,
when going round a curve, cyclists lean over.

2.3.9 says that cycling organizations are stakeholders. It does not
say that cyclists are stakeholders. That's truer than they know.
The bureaucrats get terribly upset if confronted with a situation
where there is not complete unanimity among cyclists. They regard it
as "unhelpful"

There's a whole chapter on "plain links", without any special bike
facilities. It says that such things are ok, so long as the speed
limit does not reach the value of 30 mph (see 3.1.4)

3.1.4 talks about avoiding undue risk to cyclists by design bike
lanes "with care". What on earth does that mean in an engineering
document? The road to hell is paved with good intentions, the bike
lane to hell is designed with care.

3.2.4 says "Authorities are required to review all pedestianised town
centres served by LCN+ routes, with a view to encouraging cycling."
If it's an LCN+ route, I would be satisfied with their just
legalising cycling. And doing the same at places which are not LCN+
routes.

That's just a sample from flicking through the first part of the
document

Nearly fifty years ago Professor Sir Colin Buchanan wrote in his
book "Mixed Blessing, The Motor in Britain"
"The meagre efforts to separate cyclists from motor traffic have
failed, tracks are inadequate, the problem of treating them at
junctions and intersections is completely unsolved, and the attitude
of cyclists themselves to these admittedly unsatisfactory tracks has
not been as helpful as it might have been."

Nothing changes

It seems to be happening all over! Twickenham bridge in west london had
a gloriously useless narrow cycle lane placed right on the edge of the
pavement next to a very busy road with the path zigzagging around each
lamp post. In the past few weeks the cycle lane has been moved to the
middle of the path away from both the traffic and lamp posts and made
wider.

I balked at the sizes of the downloads.

BTW what is your web site URL?


Does it properly address:
* The night time cycling environment
* Greasy/slippery surfaces eg near building sites and turnings and on
tables with paviours
* Dropping kerbs at side access points and keeping parked traffic away
from these entrances
* Dealing properly with diversions
* Traffic reduction
* The negative impact of many traffic calming methods
* The over-use of zig-zag barriers


Is there any audit procedure?

? Trailers (and etc)
? Braking distance

I also carry silver bullets and garlic when dealing with these wonks.

Eh? The authors obviously think we all go around on 'my little pony'
bikes with stabilisers.

Absolutely.

It does talk about lighting, though I didn't read that section. It
talks about skid-resistance of surfaces, though only in general terms
(I suppose it assumes that wetness is caused by rain). It does talk
about dropped kerbs (they must be flush) and junction sight-lines,
though I don't remember anything about sight-lines being obstructed by
parked cars - perhaps that problem is what sight-lines are all about. It
doesn't talk about diversions. A large proportion of the document is
about traffic reduction and the impact of traffic calming on cyclists
(e.g. it explicitly states that the national standard kerbside gap for
cushions is too small - 70cm - and 1.5m is preferred). It explicitly
says that cycle routes should not be obstructed in ways that force
cyclists to lose momentum or which cause problems for trikes or motorized
wheelchairs, and that if abuse of cycle lanes by motor bikes is a problem
then technological solutions (licence plate scanning) should be used.

Oh, sorry www.jfparker.demon.co.uk/bikepapers.html

Lots of outdated stuff and broken links. My comments about the
London Stds probably won't mean much without the original doc' in
front of you.
