Hello - and welcome.
Let me first of all say that we all agree that deaths on the road should be reduced, preferably eliminated. Let me also say that NONE of the core membership/supporters of SafeSpeed condone law breaking, nor wish to see speed limits abolished, nor wish to see the arm of enforcement (by trafpol) removed.
However, ask yourself this: A hazard as you drive along in front is developing, which (for whatever reason you cannot at this stage see). It is a known spot for problems, so a speed camera has been erected to enforce speed limit compliance. Where would the driver's eyes be best placed approaching this developing hazard. At the speedo a few times to ensure compliance with the limit, or up ahead throughout, even if the speed limit is being nudged by a little?
I guess in this scenario up ahead throughout. To change the subject slightly, I think what would be great is if we could all buy cars with satellite-linked speed limiters, so that our speed was automatically kept down. I would quite happily use one.
But that remove the skills again... und take away responsibility.
People become over -reliant.
In any case .. satellites can freeze lock .. or not lock at all on high ground .. in passes.. under bridges .. in tunnels.
Und look at the errors in the wars .. those satellite guided bombing raids did not exactly reach the correct target in too many cases

I do not have such blind faith in gadgets.

In a nut shell, because they are increasing (in real terms) the death toll on our road, for a multitude of reasons, side effects if you like.
No I don't accept that. If fatalities are going up then there are a number of possible causes, such as increased mobile phone usage (which has exploded over the last 10 years). Take this comment from the following document:
"A major two-year DfT study of speed cameras across six areas found a 35% reduction in people killed and seriously injured at camera sites, compared to long-term trend."
http://www.pacts.org.uk/policy/briefing ... iefing.pdfUnd another piece of research found that this starting part was flawed.. BMJ - Pilkington. Not peer reviewed piece by the way..

But basically.. he started off supporting the cameras ..but then found the data collated was too variable und not scientifically consistent enough to make such claims per his follow up piece .... but you now have to pay to view BMJ articles .. or subscribe to view.
Thus.. if the data ist inconsistently collated .. then you cannot base a fair set of stats or any useful information regarding efficacity of these cameras.
Thus you cannot und should not conclude that these gadgets "are useful in saving any lives und build a whole road safety policy upon it"
My work has to be a lot deeper than that.. more detailed with each i dotted ... but then ,.. if I get it wrong .. people would die und firm's reputation on line.. und worse than hell to pay for it.

Every collision involves speed - momentum. However, free travelling speed and impact speed thanks to braking etc are vastly different. Nobody on here condones driving too fast for conditions, ie, exceeding a speed in a given situation where one can comfortably stop within the distance one knows to be clear. The report from which you quote has so much spin in it it is almost dizzy! Others will drop links to the analyses that have been carried out without the spin, but the long and short of it is that, of the 25% "too fast", only 3% were actually too fast and in excess of the speed limit. Too many, but only 3%. The other 97% (of the 25%) were too fast, but within the speed limit. Cameras will not catch such bad behaviour. What they will do is distract the driver who is already being foolhardy.
Firstly, I'm curious as to which document you think I'm quoting from! I've heard all sorts of different percentages from different places, so I was just selecting a couple of round numbers really. As for the document linked above, here are a couple of quotes:
"Figure 2 shows that even slight decreases in speed are beneficial, especially for death and serious injury. Research by TRL has indicated that reducing the speeds of the fastest drivers would yield the greatest
benefits in reducing death and injury on the roads."
"Finally, she notes that excessive speed was recorded as a factor in more than a third of the fatal crashes recorded and that the contribution from other speed-related factors ‘will mean that the true effect of speed is
likely to be even greater than this’."
I accept that excessive speed isn't necessarily the same thing as exceeding the speed limit, which is why I suggested a couple of lower figures. A crucial question is this: where do you figures come from, and why should I accept them over what other organisations say?
Because you cannot really accept any of these figures. But you look at what ist really happening .. und you should be intelligent enough to draw your own conclusions.. namely that KSI ist increasing.. appears to be increasing everywhere .. apart from the few regions which rely on policemen still... und driving standards are not very good .. but marginally better in the old fashioned style areas ..

You also look where these yellow tins are situated .. where the vans are.. und observe the silly ways in which they try to conceal.. behind bus shelters.. removing line markings in Lancs for example

Even if it's only 10%, then that's still 300. And this isn't counting all the accidents resulting in serious injuries, ruining someone's life.

It is under 3%.
See above.
You quote a DfT document. Ist going to be biased .. und Pilkington even commented in first article that he could not draw a definite conclusion due to the non-stratified, non -standard data collated for these scameras.

I suggest you read a bit more from other sources

So assuming that you agree with having speed limits, then surely they have to be enforced somehow?
Roger wrote:
Absolutely they have to be enforced, but with appropriate discretion. Cameras cannot do that.Sure they can be set at a numerical value some distance above the posted limit, but this is not the discretion to which I am referring. I am referring to discretion taking everything into account. Take an example of a camera placed on a road that is 40 mph, and traffic has built up behind a slow-moving vehicle (say 25mph). An opportunity to overtake presents itself and one marches swiftly by. perhaps touching 50, then returning to just under 40. Provided the overtake is otherwise carried out corredctly and with due regard for hazards, this is the discretion to which I am referring. A camera would have copped the overtaker, yet a discerning police officer may judge this sensible and carry on with his duties.
On the same road, the traffic coming the other way and activity at the side of the road may be high, with ptotential risks of carriageway incursion. Travelling along at 45 - still within the camera's "discretion", may well be absolutely too ofast for the conditions (perhaps 25 - 30 may be right taking everything in to consideration). A traffic officer would rightly stop this and have words, and have the option of prosecuting under the absolute speeding offence depending on how the stop progresses.
Well, good points. I don't know whether enough police officers are discerning enough though.
Most are. They are surprisingly well trained und not necessarily out to get you. IG und Ian says a good officer will use judgement und punishment should be last resort when all other measures fail.. or act was so bad that there was no other option open to them

And let's not get into the silly "so you think that driving 1mph over the limit is dangerous do you" argument, because there is always leeway given.

This is the camera's argument, not ours. Whatever number it is set to, 35, 36, 38.... exceed it, no matter how safe, and land a ticket. Stay below it, no matter how dangerous, and do not land a ticket (although possibly risking life and limb).
Okay, I may be a bit biased here, but with everyone racing round my local roads at, say, 50, I would simply be delighted if they were kept to below 30. When I've seen so many cars drive at 50, I would find it very hard to see someone that was doing 25 as dangerous.
If everyone drive on these roads at 50 mph.. perhaps that ist the limit?
I do not see people driving at more that 35 mph on 30 mph roads up here. 38 mph ist speed cut off for the Lancs course these days now too

I see the odd one which I judge to be closer to 40 mph though. I am usually at 27 mph per the origin though!
