Hi Max,
It was supposed to be a reply to the original post rather than a follow up. My error.
Even so, I'll stand by what I say. I have a keen interest having worked at GM involved in testing automotive safety engineering development in the 90's, and then undertook a complete career change to become a Paramedic.
I've seen the work that goes into both preventing the accidents, and done the work that goes into cleaning up afterwards. It gives some interesting perspective to both jobs.
There's no question that work started to try and slow people down late last century has had an impact on the road toll. I won't deny that.
But you can't change the behaviour of all of the drivers all of the time, and you can't take driver error out of the equation.
The biggest developments in mortality & morbidity reduction in the past ten years have been in vehicle safety, and road safety improvements. The same as the biggest single factor in the reduction in the 70's was as a result of the introduction of compulsory seatbelts, the big factor now is improved crumple zone design and supplementry restraint systems.
Road design removing gravel shoulders to allow a nearly certain crash to become a near miss, and armco or rope barriers to prevent cross over head-ons on divided roads or excursions into trees or off embankments, and fixing bad intersections and off camber corners or those with changes in radius part way through have contributed and will continue to contribute more in the next ten years than people slowing down by 5kmh.
The double fatal I attended last week was on a bad off camber corner on a national highway with gravel shoulders, which has been the cause of fatals in the past. The double fatal before Christmas was on a corner that is on the same highway further toward the border where a car coming around a corner that tightens as it progresses, and is slightly off camber, crossed the double lines.
5kmh wasn't going to make a significant difference and while there is an element of error on the part of a driver or driver in any crash - there's no suggestion at this stage that excessive speed was a factor, and had the driver passed through a speed camera half an hour or 5 minutes before the ticket would arrive after the funerals are over.
East of
home all the way to the border there are so many poorly designed corners - off camber predominantly being the problem - on the highway. It's not surprising that several of them are marked with crosses.
Governments won't admit that roads and automotive safety design have a more significant impact on the road toll than speed cameras as it doesn't support their argument for that form of tax collection.
I'm not exonerating the drivers. Driver error or lack of judgement is a factor in most crashes, but there are other contributing factors that cause the error or lack of judgement to become a crash rather than a near miss.
ABS Brakes, Electronic Stability Control and road design promote an increase in near misses subsequently reducing crashes, morbidity & mortality.
I don't condone speeding, but I don't condone tolerances on speed cameras that are less than the ADR tolerances on speedometers either. I do fully support changes to government policy on road design and blackspot prevention.
