Cheese wire barrier - Upper Hutt

[sAsLEX]

The design parameters for the barriers specify the strike angle range, that is they are effective only at strike angles of around 30 degrees or less. Generally, the further the barrier is from the road, the greater the strike angle. This is why they are installed near to the live lanes, and also why there is one either side of the grass median on the southern motorway.
So make sure more people crash in to them to ensure they work right? Seems dumb reducing the width of available road to use a cheaper barrier, they remove the emergency stopping part of the road, like at Rangaaririririr now the tractor drivers hold up SH1 as they cant meander along the side of the road no longer

In regards to their "strength" compared to concrete barriers, there is a 5 point scale (1 has the lowest stopping power - 5 the highest). A w-section barrier (or armco as they seem to be known) are Test level 3. Concrete barriers (new jersey barriers) are either test level 4 or 5, depending on their height. A test level 4 or 5 barrier is designed to stop trucks. A test level 3 barrier is designed to stop cars.

You failed to say what the wire rope scores?

And of course, compared to other barrier types, wire rope barriers are cheap.

Not if vigilantes cut them down every second night........

Clearly Ixion and I disagree .

Using entrances etc can cause other concerns like someone pulling out of them (even by a little)...esp when youre distracted by looking in your wing mirrors at the impatients.

The wire rope barrier is a Test level 3. The same as the w-section/ armco barrier - but cheaper to install and maintain.

What maintance does Armco require?

Does the wire not require re tensioning?

And I thought the reason behind wire rope was that it could stop car vs trucks but its not up to that standard?

Stopping power largely irrelevant for motorcycles... highlighting that barrier design specifications for do not include crash worthiness for motorcycles.

The double barrier area I was talking about is north of Rangiriri. I don't remember anything of strategic value to be protected there? A farmers fence maybe?

Armcos are costly to replace after they are struck - rebore holes for posts - replace armco etc. The end terminals alone are around $4000 each.

For wire rope barriers the posts are fitted into a socket in the ground - you pop a new (cheap) post in, and retension the wire if needed (usually they are ok).

And the wire rope barriers are not designed to stop trucks. I have seen footage of a wire rope stopping a truck, but I've also seen trucks run over them like they wern't even there.

Hmmm thats a solid point that could be used to argue against there inclusion as the primary lane dividing method being currently utilised by the Govt. It aint even safe, let alone to silly motorcyclists, but even to Joe Voter in his Family car if a truck crosses the centre line.

Yes the cheese cutters may stop a vehicle from coming onto your lane and smashing you, but if you get pushed wide by a vehicle changing lanes without looking and you get rammed into one....you'll more than likely loose limbs. They're fucking dangerous. So your riding to the conditions is a load of shit. Concrete median barriers are the way....but of course...they cost too much. Whats a few limbs eh.....

There is alternatives to naked wire rope structures. The plating of them with plastic coverings can retrospectivaly increase there safety towards motorcyclists without degrading their vehicle stopping power, and does not cost much. But the killer is that it does cost and they are trying to cut every dollar they can.

As far as I am concerned they shouldn't be put up anywhere.

[sAsLEX]

the words "shoulder" and "chip" come to mind.

You are right.

The placement of these barriers often reduces the shoulder available on the chipseal road.....

Well I'm glad to report that I have been given permission to ride my bike as I can lift it on my own from off the ground. (I am so proud of myself.)
Mrs KD.
Oh, and as for the "cheese cutters", having not as yet had an incident with them, I have no major problem.
What I do have a problem with is the corner in question, and in saying that, not so much the corner but the intersection before hand and the wankers who think that just because they are in a 4x4 or Volvo that we can just wait for them to drive infront of us.
I always slow down when approaching there, knowing that it is quite common for someone to be crossing the road or pulling into my lane and I will be the one who needs to react quickly or dieeeeeeee.

I have moved the unnecessary posts to PD...

Im getting complaints via pm and reported posts about a thread that should really not need to turn to crap. Yes everyone has the right to thier own opinion, but there is a time and a place for everything, this is not the place...

Keep it clean guys.

Never actually expected that I'd get the response that I did, but sadly can't say I'm surprised. A few fragile ones out there got upset over the choice of words I used, sorry to you. I'm used to stronger personalities that don't get upset over such small things. But it would be boring if we was all the same, although the flame fest would be fun

Complaints??? Clean??? You are having a laugh aren't you Joni? I didn't use one single expletive in my posts. Just merely standing for the majority.
Quick...put this in the PD bin before anyone reads it! Done and dusted.

Stands in corner with his hands on his head.

Farm fences is not a valiud comparison. Almost always there is a ditch or verge between the road and the fence. Moreover farm fence posts snap relatively easily (don't they Postie?) and the wires pull out with not much force.

The "ride top the conditions" retort is just a cop out. On that basis you would need to endorse people chucking lumps of rock at motorcyclists from overbridges. That could be addressed the same way - Concrete being chucked at you? Ride to the conditions and avoid it.

There is no logic that says people should not object to the unnecessary introduction of an extra hazard. Riding to the conditions means riding so as to deal with the hazards there unavoidably are, not supporting adding extras ones needlessly.

And while the "stopping vehicles crossing the centre line" has some merit (but only some) that cannot be used to support the use of cheese cutters on the left hand side. Or the examples on SH1 where there is a double line of cheesecutters with a nice median strip BETWEEN them.

Ixion, far better said than anything I could've written....I'm with you 100%
