  1. Talking about pinch points where cyclists become invisible.

    There is a consultation in my local area for new traffic measures,
    aimed at reducing speeds.
    I went alon on Saturday to the public consultation, where two engineers
    from Mott MacDonald were showing plans on a board.

    The main comment I made was that a chicane they planned was dangerous
    to cyclists - and pinch point tempts motorists to squeeze past you.

    I talked with one of the engineers, and he was surprised that I was
    against any on-road cycle lanes. They had an 'advisory' lane on the plan,
    which in my opinion does no good.
    He mentioned mandatory lanes - but what difference does a solid line
    make to a ten-tonne truck running you over...

    Also I'd like to hear what people on this list think of anit-skid coatings.
    Good or bad? Is it bad to have something which helps speeding drivers
    slow down?

    Another aspect of the plans was a red coloured central strip on the road.
    At the moment it has white and maybe hatched white lines.
    Red tarmac and chippings any good?

    Two things I did welcome:
    a) electronic signs which flash up when a driver is speeding
    b) raised tables at the entrace to side streets

    Mixed views. Don't think it helps slow them down unless they woudl have
    skidded, might make them compensate for it being there in fact.
    However, it does extend a fair way back from the junction in most cases
    that I've seen which can add a wakeup call to them that there IS a
    junction coming up.

    If it's not got hatching laid over the top then there's no clear
    indiction what its for. Then again there are quite a few who ignore
    hatching signs these days. If it's red and hatched, it might register
    on their radar again, otherwise, just pretty paint really.

    a) I like these too. I reported a bus driver for speeding. I was on
    the bus, I'd already thought he was speeding, but when the sign went off
    I knew how much by 😉

    b) yes, and no. Yes they slow traffic down, but they can be a right
    pain in the [censored] when on a bike sometimes - they're actually quite high
    with a / angle to them, rather than a more gentle tarmac slope, at least
    round here.

    The only safe place to cycle for a pinch point is bang in the centre of the lane
    to stop
    traffic even *thinking* of trying to squeeze past.

    The surfaces are often rough and vibrate through the whole bike.

    Central hatching keeps traffic nearer the edge, which some cyclists may not like,
    but it does mean that overtaking traffic has more room to overtake if opposing
    traffic is kept nearer the edge, so yes i'd say it's a good thing.

    These things serve to indicate to motorists how far they need to

    road. I am not sure they do anything else.

    Er, I think they help all car drivers slow down. Non-speeding drivers
    will skid if they have to brake hard when somebody pulls out of a
    junction when not looking. I'm sure anti-skid surfaces have helped
    reduce road casualties a damned sight more than speed cameras.

    Only this morning somebody pulled right out a junction in front of
    them when I was plainly, clearly in view and driving a massive black
    and white car. I was quite well clear of hitting them but had I been
    much closer I expect the anti-skid surface might have saved my ABS
    from being tested.

    Hatching only means "don't drive here unless you have a reason". And the

    areas, though of course not all drivers are mentally wired in that way ;-)

    Ah, actually, having just looked it up, there's two different kinds
    (excluding the chevron types on motorway junctions, which isn't
    applicable in this case unless the planners have done something truly
    bizarre!).

    Single continuous white line bordering it means you should not enter
    unless in an emergency. Voluntary overtaking manuevre not permitted in
    this instance, ending up in it while swerving/braking to avoid causing
    an accident probably more the sort of thing they mean ;-)

    Broken white line bordering means you shouldn't enter the area unless it
    is necessary (bit woolly, my interpretation is that overtaking using the
    hatching isn't *really* necessary unless you know there's no other
    chance to overtake a very slow vehicle for a long way ahead) and you can
    see that it is safe to do so.

    I'd say really you shouldn't be driving over a hatched area unless you
    have a very good reason, overtaking not being one of them, really,
    unless, as I said, it's a very slow moving vehicle.

    Apparently both are there to separate lanes, or protect right-turning
    traffic.

    If you can see that it's clear to do so, why not overtake in hatching? It's

    visibility it can be possible. The only problem is that hatched areas tend
    not to be used so could have a fair bit of debris on them, but again, having
    eyes and using them helps.

    If you want to stop people using that bit of the road / overtaking, put
    solid white lines around the hatching. If you want people to move off a bit
    of tarmac for whatever reason, you put in hatching. In theory you could put
    in hatching to make overtaking easier. I really don't see the need for
    hatching in the middle of the road though - IME it encourages dodgy road
    positioning in many cases. In Norwich, next to UEA, they spent a while
    taking two cycle lanes up, and putting hatching down the centre of the road.
    End result is that everyone now drives much closer to the kerb than
    previously, which I imagine would make cycling far more difficult than it
    would be with the cycle lanes or just a standard dashed line.

    Hatching only means "don't drive here unless you have a reason". And
    the chances of being pulled over in most areas are pretty slim, even
    if you're too dim to come up with a reason.

    visibility it can be possible. The only problem is that hatched areas tend
    not to be used so could have a fair bit of debris on them, but again, having
    eyes and using them helps.

    Oh indeed, I agree, I just tend to not use hatched areas for overtaking
    - as you say, often debris lurks in it, and I don't think it's
    appropriate use of a hatched area when it's used for haring up the
    outside of someone when a dual goes to single, and passing them at speed
    on the hatching before cutting in right in front of them again... which
    is what I see much of it used for.

    Overtaking at junctions is more dodgy, and I have a vague idea
    overtaking at junctions was frowned on by the HC, but can't recall for
    sure. It's certainly true that often visibility isn't always good at
    junctions when you have the side turning to consider, which is often in
    front of the whatever that you want to overtake - if an eejit pulls out
    of the side turning into the path of the thing you're overtaking, you
    rapidly run out of road as it swerves to avoid the pulling-out eejit.

    I'm not sure how many drivers are aware of the distinction between solid
    lines around hatching and broken ones. There certainly are cases where
    hatching in the middle of the road is justified - I've seen it on sharp
    bends where drivers tend to cut the corner, in an attempt to keep them
    on their side of the road and stop them drifting over the centre line on
    the way around.

    Yes, I can see the problem when it comes to cycling and hatched central
    areas - however, I'm not a great fan of cycle lanes unless they're
    really decent width ones and few of them are, sadly. In some ways
    making the road narrower actually helps drivers cos they have to think
    about passing a cyclist rather than just assuming they can squeeze
    through, but then again there are the cases where they'll come up behind
    far too fast and squeeze past anyway just for the hell of it. Was there
    a history of head-on collisions at that point? I'd imagine they must
    have had a reason for wanting to separate the lanes - several right
    turns, or anything like that?

    I fear that an anti-skid road surface will drag at bike tyres, making
    cycling a lot more effort. That could discourage cycling.

    It may still be a good thing, of course. I wouldn't want to pass
    judgment without knowing the area and studying the plans.

    An old dear with (I presume) her two small grandchildren in the back of

    4x4 this afternoon that I had to do an emergency stop. She never looked
    to her left _at_ _all_ before her pulling out. Her grandchildren are
    alive just now courtesy of the fact that I was pootling along quite
    slowly and that I was paying attention.

    She drove off apparently oblivious. There are some terrifying drivers on
    the roads.

    Even solid white lines don't mean you can't enter the area. The law is a

    If the gap between the two solid white lines is greater than 1.2m then
    treat as though the area was enclosed by dashed white lines (maybe you

    where you can't enter the hatched area.

    Hatched areas can be a good place to overtake because you can be
    reasonably confident that the car/lorry infront is not going to
    start drifting over and if someone does come hurtling the other
    way at 120mph there is still room for you all to pass

    This isn't what the highway code says.

    It makes no mention (unless it's in the double-white-lines bit) of the
    width of the gap.

    It does make it abundantly clear in the words I described that a solid
    white line means you MUST NOT enter the hatched area EXCEPT in an emergency.

    And hatched areas aren't always big enough to prevent the head-on you
    describe from happening.

    Talking about pinch points where cyclists become invisible.

    There is a consultation in my local area for new traffic measures,
    aimed at reducing speeds.
    I went alon on Saturday to the public consultation, where two engineers
    from Mott MacDonald were showing plans on a board.

    The main comment I made was that a chicane they planned was dangerous
    to cyclists - and pinch point tempts motorists to squeeze past you.

    The critical thing with pinch points is that they should either be:
    a) Wide enough to allow safe overtaking (4.5m at an absolute minimum)
    - in which case there will be no traffic calming effect at all. OR
    b) Narrow enough that not even the dimmest of drivers would contemplate
    attempting to overtake (less than 3.0m).
    Anything in between is bad news for cyclists. Unfortunately engineers like
    to compromise so you tend to end up with 3.5m gaps (ie not wide enough
    to overtake but not narrow enough to make this obvious to drivers).

    I talked with one of the engineers, and he was surprised that I was
    against any on-road cycle lanes. They had an 'advisory' lane on the plan,
    which in my opinion does no good.
    He mentioned mandatory lanes - but what difference does a solid line
    make to a ten-tonne truck running you over...

    The key thing with a cycle lane is the width.
    Anything less than 2m and you are better off without it.

    Advisory lanes are better - because motor vehicles are allowed to encroach
    the cycle lane then the engineer is permitted to make the general traffic
    lane
    narrower than the vehicles using it and maintain a full width cycle lane.
    (ie a 2m cycle lane next to a 2.5m traffic lane). If vehicles need to
    encroach the
    cycle lane then that is no problem - so long as there is no cyclist using it
    at the time.
    If there is a cycle lane then it indicates the amount of space the cyclist
    needs.

    Unfortunately most engineers are idiots - at least when it comes to
    designing
    for cyclists - so they get everything the wrong way round. They insist on
    maintaining
    a full width traffic lane (which they would have to do with a mandatory
    lane)
    So you end up with a half width cycle lane next to a 3.5m traffic lane. This
    positively
    encourages dangerous overtaking and take space away from cyclists.

    Good or bad? Is it bad to have something which helps speeding drivers
    slow down?

    Yes. As with most safety features they treat it as a performance enhancement
    and thus approach junctions faster, knowing that they can brake harder.

    The dressing is also awfull to ride on and tends to be lumpy.

    Another aspect of the plans was a red coloured central strip on the road.
    At the moment it has white and maybe hatched white lines.
    Red tarmac and chippings any good?

    These are good, as drivers can use this to overtake cyclists with greater
    clearance - so long as they don't put islands in the hatched bit.

    If the traffic is clogged these enable cyclists to overtake queues more
    easily.

    Two things I did welcome:
    a) electronic signs which flash up when a driver is speeding
    b) raised tables at the entrace to side streets

    They need to be carefull to set the tables back so that you don't ride
    up the ramp at a tangent if you are turning into the side street.

    If you want to stop people using that bit of the road / overtaking, put
    solid white lines around the hatching. If you want people to move off a bit

    <snip>

    Even solid white lines don't mean you can't enter the area. The law is a
    mess - IIRC (and check up on this before you rely on it :-)

    If the gap between the two solid white lines is less than 1.2m then you
    can't enter the gap (treat as double white lines)

    If the gap between the two solid white lines is greater than 1.2m then
    treat as though the area was enclosed by dashed white lines (maybe you
    can't cross the further solid line?) UNLESS this area is on a motorway
    where you can't enter the hatched area.

    Hatched areas can be a good place to overtake because you can be
    reasonably confident that the car/lorry infront is not going to
    start drifting over and if someone does come hurtling the other
    way at 120mph there is still room for you all to pass

    Tim.


    This isn't what the highway code says.

    It makes no mention (unless it's in the double-white-lines bit) of the
    width of the gap.

    It does make it abundantly clear in the words I described that a solid
    white line means you MUST NOT enter the hatched area EXCEPT in an emergency.


    But there are other places where the highway code is wrong - or at least
    economical with the truth so one more doesn't surprise me. But for this
    one, like the one about overtaking approaching a pedestrian crossing,
    if you follow the "guidance" in the HC you won't unwittingly break the
    law even if there are times when you can break the HC without breaking
    the law. (But remember that failure to follow the advice in the HC can
    count against you if you do have an accident even if you don't break
    the law)

    This hatched area issue comes up regularly on the IAM forum (IAM members
    only) but it appears that the actual law (Traffic sign regulations ... )
    will cost $$$$$ (GBP :-) and I don't have a copy so I'm only quoting
    others.

    And hatched areas aren't always big enough to prevent the head-on you
    describe from happening.


    No, but if they are wide enough to fit a car in then you can be
    confident that they are >1.2m and if you can't fit a car in them
    then, unless you are better at estimating distances than me, you might
    be pushing your luck with the 1.2m bit anyway.

    Might be useful...

    http://www.thebikezone.org.uk/thebikezone/campaigning/pinchpoints.html

    Very much so. The thing that bugs me about pinch points is that, as
    far as I can detect, cyclists are not thought of at all by those who
    put them in.

    They are good at frightening inexperienced cyclists, who don't know to
    claim the lane. Drivers racing to get there first and then cutting in
    can happen to any cyclist.

    The widths to remember are 2.8m and 4.5m. If the islands have to be
    there, making one side narrow enough to prevent overtaking and the
    other wide enough for it to be safe is better than putting them in the
    middle.

    If an island is for pedestrians, a zebra crossing is a better option
    if the road is narrower than 10.2 m or so.

    One island I know of seems to be to prevent head-on collisions on a
    blind bend. The correct solution is surely a speed camera.

    This is relevant to me: I have some money to modify some existing
    pinchpoints, but there's no spare road width and it's not easy to get
    authorisation for speed cameras.
