The new Average speed cameras on the A40 /westway West Lond
Discussion
Dave Finney said:
There are now over 7 average speed cameras on the A40 into and out of London.
The way they work is:
each camera sends video to a computer
the computer scans the video looking for number plates
when it sees one it:
1) records the picture
2) reads and records the registration number
3) records the time
So, for each camera, there's a picture of every vehicle that passed, with it's No plate and the time.
The computers then subtract the times of each vehicle between cameras and, knowing the distance between each camera, they can see if any vehicle reached a following camera in a time shorter than is allowed. If so, that vehicle must have travelled faster than the limit.
Note, it doesn't matter what speed you pass each camera. You could do 80mph past every camera and you shouldn't be prosecuted for speeding, so long as you stop for a while in between each pair of cameras!
You'll also note that every single vehicle is photographed, speeding or not, time and time again as it travels. This means the authorities know where every single vehicle was, and when it was there, day or night, all of the time. They might also see from the photographs how many occupants in each vehicle, age, sex, descriptions etc. This can be very useful to track terrorists, criminals, demonstrators, activists, political opposition groups, and anyone else the authorities may wish to monitor.

For every vehicle that is found not to have exceeded the pre-set speed enforcement threshold the data and images for that vehicle is deleted from the system.
I have corrected that for you.The way they work is:

Perhaps you should check the facts before you publish.

So we know the data will be gathered and we know it will be extremely useful, not just for speeding, so why would they delete it?
Suppose I was going to commit a murder. If I got someone to take my car and deliberately get done on a camera, at the time I was doing the killing, and them if I accepted the blame for the offence, took the 3 points and paid the fine, when they came to arrest me for the murder, would the fact that I'd already been accused, charged and found guilty of another crime committed elsewhere at the time of the murder get me off. Even if they knew it was a set up? Some kind of double jeopardy type law?
I guess not, but it's worth knowing for sure!

We know that tracking everyone's movements could be extremely useful for the authorities, not just as I have mentioned, but for other less obvious uses. As a simple example: tracking population movements to improve public transport services.
So we know the data will be gathered and we know it will be extremely useful, not just for speeding, so why would they delete it?
I agree it would be useful...but it is not used, is not made available to the operator of the equipment and is delected by the machine when there is no speed violation relating to that data. Of course you can continue with your unfounded assumptions but you have been told they are unfounded and wrong. Perhaps you have been to journalist school.

It is only double jepardy for the same crime. Speeding and murder are two different ofences so no double jepardy there. I guess not, but it's worth knowing for sure!
Maybe you could get someone from a motoring help website to say to the court that you did the 2 crimes on the same occasion so you can get the court to consider it as one offence.

Is it anything to do with TFL?
Yes, TfL say: ""Transport for London (TfL) has begun work on a programme to overhaul the capital's road safety camera network ... TfL will be replacing older cameras with an Average Speed Camera system ... •A40 (between the Polish War Memorial and Paddington slip road)"
Ok,a member of my local forum ,seems very clued up ,he says they are going live 21st Aug,me Im not taking any chances before though.
Re the poster now going to use the M4...im not saying do it,I dont but I was a passenger in my old MDs car was coming in and he was passing the 60 mph cameras at 80 plus and well over the 40 mph one further towards London around heathrow/brentford ,I said are you mad ,he said hes been doing it for years they are not in use.There you go

At my customary travel times, i.e. in the rush hours, the chance of doing 40mph would be a fine thing! That said, the school holidays have (mostly) been great with traffic flowing at 50+ up to and past Hanger Lane. When there is little traffic - early morning or over Christmas, say, and you're looking at 3 empty lanes - that's when sticking to 40 or 50 will take real self discipline!
Speaking of Hanger Lane. what's with the 30 limit through the underpass? Absolutely no one slows down to 30 if the road's clear. The other evening I had a police car behind so actually did slow to 30. He sat behind me for 50 yards before deciding he'd had enough and pulled out and passed me!

This thread has just made up my mind for me, it's the M4 into Lundin from now on. Both the M4 and A40M arrive not-to-far from each other in the West of the capital.
That is the most difficult of confounders to remove from speed camera results, even scientific trials can't do it!It has long been known that some of the collision reductions at speed camera sites may be due to traffic diverting to other routes. That effect may be less significant recently as the speed camera program has expanded because many/most routes might now have speed cameras. This effect of traffic diverting may well return with the new fashion of installing mile after mile of average speed cameras.
Would motorcyclists be more likely to divert away from the A40 (say to the M4) than cars?
I have actually changed my commute from my primary job to my second job from the M40 to the M4 in my car three weeks ago because of these cameras (M25 to Hammersmith).
I am not losing any time although i am gaining about 12 miles in distance.This is because the A40 was always bad because of people jumping into the Hangar Lane exit on the way into town too late and causing tail backs up the A40.
I have made a conscious decision to avoid the A40 at all times now including leaving the West End on my motorcycle and taking the Westway to Shepherds Bush.
I am now using the A4 out of town instead.
The cameras are a sad day for people who enjoy driving.
