New Wide-Range Average Speed Camera System Approved

aj2052 · Posted: Fri May 06, 2011 11:31 pm Post subject:

I can see problems with average speed cameras over longer distances, bearing in mind the difficulty of relating average speed over a distance two problems immediately come to mind:
1) Driver gets held up by traffic or whatever then speeds up because in his own mind feels that he is under the average speed.
2) In the checked section perhaps the driver feels he has exceeded the staed average speed so he then slows down to a crawl and thus creating a backup of frustrated drivers.
niether of these scenarios are conducive to road safety.

Yes, but read the article not the headline ... Smile

I read the article. The report is not statistical evidenc as MaFt wants. Its heresay based on statistics that we are not privy too. It's probably biassed as well as it was a quote from the road safety chief who is hardly likely to say they were a failure is he?
Let me give an example of heresy based on statistice. If ther were two KSI in the first period and one in an identical second period, then KSI would be down by 50%, hooray. But because the totals are so low, and subject to random fluctuations, and perhaps improvement in car safety and perhaps better anti skid road surfaces over the period, as a hard and fast statistic the percentage is meaningless Shocked

I'd agree improvements in car safety can help, but can also give drivers a false sense of security. We drive in a nicely cocooned and quiet well sound proofed environment, and often don't realise the speed we're doing. What's clear simply from observing driver reactions when they see speed cameras is that many speed where there aren't cameras ... and for all the other reasons quoted above many drivers can't even do the simple things like indicate let alone control their cars properly at speed.

What also many don't realise is the minimal time they save compared with the extra risk to themselves and others by speeding. Cameras slow motorists down, and therefore get a thumbs up from me.

Although accepting the inevitable response of "well, they WOULD say that wouldn't they?", and that this might be a bit like trying to convince conspiracy theorists that there ISN'T a conspiracy Razz

, here's a report from Scotland's Chief Statistician about accidents in Strathclyde http://preview.tinyurl.com/5surems I'm not saying this proves the case by any means, but it is an example of (presumably) a genuine statistical exercise - I expect many more could be Googled, with perhaps some contradictory results.

But then there is also the "there's lies, damned lies and statistics" brigade.

So for those of you in any of these camps, you can safely discount any results which don't agree with your own conclusions Cool

(Who was it who said something like 'I don't let trivial things like facts affect my conclusions') Shocked

But geeting back to the original article prompting this discussion i.e. that new wide ranging average speed cameras are to be allowed I have to say that I do not have a problem with speed cameras in principle - as long as they are directed at the back of the vehicle and stop discriminating against car, van & lorry drivers who have to display a number plate on the front of the vehicle.

May be someone can explain to me how you identify a motorcycle with an ANPR device that points at the front of the bike.

I guess they are forward-facing so that they can get a pic of the driver in case of 'arguments'. It is true this is a problem with (speeding) bikers, but they don't all get away with it, for precisely this reason - see this from one of the threads here:

What's with all this 'tinyurl' stuff. What's wrong with a link that takes you directly to the subject page Shocked
