While you're here attempting to carry out a damage limitation exercise within older threads, do you want to have a go at some other unfinished threads, such as Night cameras plan to catch Cumbria's bad drivers and SPECS3?

Your yellow regression assumption placed on the chart you have supplied is naive and shows, should you be able to understand the mechanisms behind road safety performance, that you would expect the number of deaths to accelerate in reduction as the numbers become lower. It is quite obvious to anyone with a semblance of understanding of performance figures that there would be a diminished return in impr ovement as the numbers reduced, especially when you consider the rise in the volume of traffic that this chart takes into account.

But aren't you at least a BIT curious as to why, in half a century, it should have started doing this at about the same time as cameras started being used as a means of "improving road safety"? Let's face it, EVEN if this wasn't polotted on a log scale, (which I hope you now understand it IS!) the departure is quite pronounced.

What can be seen in the later part ofthe chart is an exponential decay

...in your wildest dreams, perahaps, but given that the Y axis is logarithmic, er, NO, it doesn't! :lol:

If no improvements were made to control traffic collisions and casualties in 1997 to the present day then the chart would have reversed and the situation would have been worse.
Even you would be able to see that.

Steve has already pointed out that this would not be the case. They would, of course, remain static. At times I despair of "Experts" :roll: .

Oh ,please leave Steve ,AKA Ploughmansboots /AKA the ancient Mariner /AKA the submariner , alone .He's besotted with his idea of cameras and the feeling that they do some good -so as it's Christmas - let's show him some charity and not stick them where he'd not like them .Just ignore him -he'll soon come back with another ID -HOPING that we'll not recognise him . :D .

OK -Steve ? We know that you think that road safety starts and ends with speed ,but in the season of goodwill , go and have an icy slide down some ungritted road ,then comeback and tell us a camera would have stopped the accident .You might as well stop homes in Cumbria getting flooded .
