    Safety Barrier (WRSB) Presentation - 5th of May

    I will be doing my presentation for Scigen 101 this afternoon between 3-4pm. I am discussing the pro's and con's of Wire Rope Safety Barriers with regards to motorcyclists (yes that means you).

    If you would like to attend it will be happening in HSB 688 (6th Floor Common Room), please be there on time if you do come. You can leave at any time as long as no one is doing their presentation (i.e be polite).

    I must admit that I did laugh at it myself.

    Just me I guess but all the fuss was about the effects it had on a certain rider but surely the barrier is suppose to be for vehicles...not people...and at the end of the day the cause was rider error (said in a nice way)...and how many times has this happpened since...

    It will have the same effect on any rider hitting it. And logic decrees that whether or not Daniel was an anomoly, more bikes + more cheesecutters = more opportunity for slice'n'dice. Give it time....
    And before you respond with (I know not what) yes, I know that hitting things kills bikers. The cheesecutter is just a particularly nasty way to go.
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?

    we are people on vehicles... the barriers should be safe for all road users, no matter the vehicle. and, for the record, trucks are also vehicles, yet the barriers dont stop them do they? ive never heard a report of a concrete barrier killing anyone that comes off/hits them. one death caused by hitting any type of barrier is one too many. they are there to protect, not to maim. there is a reason they have been banned/altered overseas.
    i think youll also find that rider error was NOT the only cause of that accident. dont believe everything the media and police tell you... myself, ive spoken to zapf about it, and i will trust his version over the cops or media any day of the week.

    r6... wish i could make it. instead, ill send my good luck wishes your way.

    Okay, has anyone in the "time" since Daniel was killed been killed by the barrier...sorry not trying to be irritating but I just don't assume that things will worsen...

    Heh, it's a presentation not a question session!

    Here's a small exerpt for you:

    It was found that the existing guardrail is not designed to protect motorcyclists from being ejected and cannot even redirect or retain motorcycles like other vehicles. Also, the fallen motorcyclists are not protected against hitting the exposed guardrail posts or even rollover to hit more hazardous fixed objects. (A.B. Ibitoye, 2005)

    Approximately 60% of fatal motorcycle collisions with crash barriers involve the rider sliding into the barrier (Quincey et al, 1988).

    Collisions with crash barriers result in twice the severity and five times more fatal injuries than all other types of motorcycle crash. (Schnull, 1992)

    Calculated injuries from the simulations suggest that serious injury would result regardless of speed and impact angle. (in reference to WRSB) - Research conducted by DEKRA in Germany in 2005.

    Interestingly my case is actually FOR the WRSB, but that suitable consideration should be given to ALL road users - and that existing solutions exist to not only make them safe for motorcyclist, but also make them do their designed job of 'restraining errant vehicles'.

    Fair enough but as far as the barriers here are concerned the stats have yet to be written I guess....less traffic..is that a factor....

    Not in NZ but there deaths every year in other countries relating to WRSB's and also with riders being at or below the speed limit - and as the use of WRSB's are increasing, and there are increasingly more motorcyclists on the roads, the numbers are increasing too.

    So your position is do nothing until X people die because of them?

    A paper was released by LTSA/LTNZ (whatever the fuck they are calling themselves at the moment) stating that the cost of ONE death on the road in NZ has a cost to society in excess of $3mil. - so if for every $3mil spent saved one live we'd still be making progess.

    I guess horse for courses though...most other counties have more motorways, more traffic, more accidents / more bikes and higher speed limts / speeds...I mean in UK 90mph in fast lane is common place...in NZ I would say 75mph is the norm.

    It may be that in NZ the WRSB's are suitable...I mean in NZ we often say how we know best..

    id rather we didnt give them the chance to worsen before we did something. plus, at even 70k, you will lose a limb if you have the misfortune to come off and connect with one. these barriers are not suitable for any country.

    lets switch things around and pretend the person killed was a child of yours. would you be happy to sit back and assume things wont get worse, after seeing your child in more than one piece?
    not only traumatic for family and friends, but also for the emergency workers who had to pick daniel up and the mortician to try and put him back together for the funeral. im fairly sure that those people would happily go a lifetime without having to see that again.

    In some ways yes...I am just not a knee jerker....$3 million..how is that worked out...is that "actual" extra costs or just the cost of what is involved which is different...the people involved are paid a salary which is the same what ever happens....
