Wire Rope Barriers

In Tasmania they don't like the posts popping out of the ground when the
wire ropes are in action. Seems it's taking too long to re-align the
uprights and a bit costly to get new ones, so they're concreting them into
the road.

In places we have them less than a metre from the edge of the lane

Somehow I don't think my safety is being enhanced by this stuff.

 

Because of the angle which you hit them. A solid concrete barrier hit at an
acute angle would allow you to slide and/or roll in the direction of the
barrier while hitting a solidly mounted vertical upright (or a tree) at
right angles to the direction you're travelling would not. Simple physics
really.

Except he said it was a tight downhill bend... Wouldn't that suggest he
didn't hit it at an acute angle.
I've seen what happens to a motorcylcist that hits a concrete
barrier/embankment at an obtuse (?) angle.
Massive internal injuries/bleeding. Dead on side of road within 40mins

You undermine your attempt at an argument.

On the facts I doubt rider training would have made much difference,
however the barrier in question wasn't implemented to the appropriate
road safety standards, and if it was a car driver involved, given they
do indeed have a lower standard of training than motorcyclists,
including a far lower average rate of post licence training

Because the poeple who build it aren't neccessarily the people who have
to maintain it ?

Who builds roads - federal and state.

Who maintains roads ? State and local govt.

You work it out

Yes Richard, hitting things when you come off a bike is bad news, there
are however survival probability differences between various impacts -
realistically a m/c-ist hitting any hard object at right angles isn't
going to get up and walk away if he's doing any speed at all. There are
however very big differences between survival rates of different
roadside furniture. If you are genuinely interested and not taking the
piss I can send you on CD a whole heap of studies.

I'd be interested in that too.

I'll send you a copy of the report I was involved in when it gets finished.

I was wondering if there are different types of WRB's as with all the
ones I've seen (in VIC) the uprights are made of rather flimsy plastic
that would do little more than give a person a nasty bruise, they are
there mearly to hold the rope at the right height?

Plastic? The ones I've looked at are 1/4" or so galvanized steel,
bent into a gentle S-curve for rigidity.

(with a little plastic cap on top.)

Have you had a close look at one?

I doubt they are made of flimsy plastic, I doubt that flimsy plastic would
hold up multiple strands of 25mm steel rope, and I doubt that you would only
get bruised if you hit one (or more) at anything above walking speed.

 

And even if they were 'flimsy plastic', that means one of two things.
That they bend, or that they break. And the latter... Sharp jagged
plastic at medium to high velocity...

I'd be interested in that CD John. I can send you a blank CDR and return
postage if you prefer.

Contact me off list at "james AT grayonline DOT id DOT au"

Remind me not to make offers on this newsgroup <grin>

Righto to those who responded I'll dump what I've got on CDs some time
in the next week or two (I'll try not to do my usual and forget :-(

JL

 

I have to admit i'm interested too.
Can you shoot me an email at msim @t iinet d0t net d0t au so i know where to send a blank cd-r if you wouldnt mind please.

Cheers,

Oh friggin' heck ! What have I started* ?!

Zebee I think I've found something to put on your top 5 list !

OK, I faithfully promise to collate all the safety study docs I can lay
my sticky little fingers on (including a number the ACRS have promised
to make available to me) and make them available for a) download and b)
by CD to a limited number

Time frame 1-4 weeks (life's busy)
