so im going at 50 down motorway between the average speed check cameras when a cbrrrrrrrrrrrrrrrrrrrrrrrrrrrolfharrrrrrrris goes flying past at at least 80/90mph....got me thinking......
do the average speed check cameras not pic up bikes (if they work on numberplate recognition) as they point face on to it (slightly down) or is it some other technology they use???
i would like to know this too because i wasnt sure if the specs camera's in the average zones only take front numberplates?

They don't pick up but you'd have to be silly to keep doing it cos i could guarantee a copper would catch you in the end.

AFAIK (not very far) they (mostly) use front facing cameras and I believe currently that they don't take into account lane changes, so if you exit the zone on a different lane they can't work it out as they aren't linked (this may change or may never have been true but I recall hearing it)
hmm hopefully someone has something other than speculation ;)

is that definate that they dont pick up bikes then???.....
im not wanting to know so i can fly down the motorway like the fool the other day....
just good to know thats all....going at 60 say when its clear in al lanes etc....

If the speed limit is 50mph why exceed it doing 60mph and break the law,same as doing 84mph in a 70mph limit-------both 20% above the speed limit. Just because there is no other traffic doesn't give anybody the right to exceed the speed limit.
Some locations also have rear and frontal facing cameras apart from the general observation cameras-----so the authorities could get your number easily if so desired

Definitely don't pick up bikes - *someone I know* has been down the A14 and the M4 (J11) at *slightly more* than the speed limit and has not had an NIP...
However, it was my understanding that changing lanes doesn't -> the cameras near the M4 flyover are a perfect example... There's a certain pattern - you have to change lanes every two or three cameras I think... But don't regularly go to the smoke so couldn't say for certain.

I would like to point out the blindingly obvious to people here, BIKES DONT HAVE FRONT PLATES!! and seeing as the SPECS cameras face forward they cant catch you.
This question was asked in the law Q&A of MCN and its a def they cant catch bikes.

regarding the lane changes. as far as im aware the old technology couldnt understand when a car changed lanes. it 'lost' it by the 2nd camera.
although it wouldnt take much wiring to get all the cameras to talk to each other, so im pretty sure they can now work when you change lanes. (in a car that is!!!!!!)

yes but this was the answer from a lawyer, they have not been type aproved for bikes , and even if they had they still cant see our plates.

I also would like to point out the blindingly obvious... Just because the SPECS cameras don't read number plates, doesn't mean they can't identify a bike as a vehicle and flag is as unrecognised.
If they do this across several cameras, flagging each exception, it doesn't take much of an operator to track a single bike, still use the speed calculation and other surveillance cameras and prosecute that way.
I assure you, it's only a matter of time. Already well in use in bus lanes and restricted zones in London...
They dont get you.....full stop.

My 'friend' regularly passes through the M1 cameras and nottingham ring road cameras without comeback.
WEll, 2 years of A2 travelling, 50mph and I didn't travel at those speeds.
No ticket.
6 months more me coming the other way, I maaaayyy once or twice seen 3 figures as i've gone passed a camera (please note MAY for the PC brigade as this is naughty).
Still no tickets...
As for the old lane change trick, 1st phase of cameras this was true, but they updated them and it no longer works.
However, im not sitting at 50mph on a brand new, 3 lane motorway, when there is no workforce round, so i've sat at 65mph quite often without a ticket in the car.

i think if you draw enough attention to yourself and do it repeatedly (wheelie at 80 in a 30 zone through a camera) then they may well invest the time and manpower to identify your bike. hence bloke with 39 points from forward facing camera, picture widely touted in the news....
Actually as these SPECS pop up and disapear so often at road works, are they actually plugged in etc? or are they just a placebo effect? as lets face very few are going to chance it.

At the moment they are only forward facing, but supposedly (I read it somewhere but don't have any links/can't remember where) rear facing ones are in developement, it will only be a matter of time as it shouldn't be 'that' difficult to link a rear facing camera to a forward facing detector.
Actually, the front facing average cameras...
Yo-u can see which ones are turned on at night. Look for the deep purple glow on the lense. If its on, u'll see it.
Much easier when one camera is on, and the other two are off.

You've never broken a speed limit? :notworthy:

They are all 'plugged in' ;)
They is quite a variable in the way that they are programmed though.
Some are only active during working hours and deactivated during the night etc......some are set at 70mph.....some are set bang on 53mph
Had the pleasure of sitting in meetings for highways at the planning stage when these things are dicussed :rolleyes:
All the temp ones for the road works tend not to have there wiring enclosed, so if you really worrried just look at the hard should and your see some cable between each junction box. Its only a light cable that could easy be damaged... I'm not sure how, but it could, rabbits, foxes, magpies.
Though I think the ones at road works are a good idea as it drops the speed lessening the chance of one the workers getting killed/injured. Though when I go through them there never seems to be anyone there.

BillyC makes a good point about the average speed cameras. Do they recognise vehicles even if they cannot identify the number plate? Or are they like ANPR (I think) and don't read anything except plates?
See, if you were to speed through those cameras, and they were to catch you despite no plate, the crucial thing is that it must take a photo of you/some other evidence of you being there for them to find you.
The guy with 39 points went through a camera that takes a photo regardless of plate - that's why there was evidence there that the police could use to trace him (the photo).
If SPECS cameras ONLY take a photo if they recognise a plate AND the plate has been speeding, then you would get away with it.
If they take photos of 'unrecognised' vehicles, then you may well not get away with it, if they put the energy in to trace you. They would almost certainly require it to take photos though, an 'exception' on the system would not be enough to prove that it was you at all the sites (nor would it be enough to even find you in the first place I suspect).
However, it might be enough for them to start patrolling the area in the hope you do it again.
So ignoring the 'we spotted something odd on the system and started patrolling' situation (which is a case of getting yourself caught for a DIFFERENT offence, not the one that triggered the 'search'), the only way they would get you is if they took a photo of 'unknown' vehicles if one were spotted.
Just don't do it in the same place twice.

I think Neio's right though, each camera type has to be specifically type approved for use on bikes for it to be admissable in court I think, so if they've not had this done for bikes, even if they can identify you by other means it wouldn't constitute proof of speeding.
Obviously, I'm not a road traffic lawyer ;)

Yup, traced his bike jacket to find there was only 2 in the country. And thats purley how they found him.
So if your gonna go on a camera setoff session, make sure you wear a jacket that every buggers got, and then it'll be much much harder :lol:

Fancy scrubbing tyres in on a motorway you crazy fool
Just to extend my point a little further, whether or not you choose to be interested. It's particularly from a computing and technology aspect.
Indeed, the guy with 39 points was not necessarily "camera'd" for each office, but an overall case was put together, which included video evidence.
A SPECS camera, like it or not, is a video camera. What makes up the SPECS system, is simply the artificial intelligence to read the number plate on an approaching vehicle, and compare it with the timing of similarly interpretted plates at previous camera points. The product of this data is a speed calculation, and where appropriate a PCN is issued.
I promise you, the AI can and will be adapted to recognise unidentifiable vehicles between these camera points, match them up across the points, perform the appropriate calculations, and flag them to an operator. If facial recognition software is being used in Airports, I assure you it's considerably easier for vehicle recognition to be put in place on our roads - it only has to compare a few vehicles a few seconds apart.
The SPECS system doesn't necessarily come into effect here at all... it's the operator that makes the call of compiling the video evidence from points A and B, the knowledge of distance X between them, and time Y to travel between the two, and finally Z, the speed that vehicle was doing. Some more footage to identify the vehicle or driver further... PCN on your doorstep.
It's not difficult, it could be done now. We're lucky that it isn't, maybe, yet.

Get a little closer to the vehicle in front for a couple of seconds when passing one of the cameras. :smt047
I can however confirm that the ones on the M56 can detect single lane changes, but not when you cross two lanes (ie, 1-3 or 3-1). I've been NIP'd in the past for a single change. Not yet for double.

I'm not sure what your background is so I don't know whether yours is an authoritative opinion ;) but a few questions crop up for me here:
A SPECS camera, like it or not, is a video camera. What makes up the SPECS system, is simply the artificial intelligence to read the number plate on an approaching vehicle, and compare it with the timing of similarly interpretted plates at previous camera points. The product of this data is a speed calculation, and where appropriate a PCN is issued.
I promise you, the AI can and will be adapted to recognise unidentifiable vehicles between these camera points, match them up across the points, perform the appropriate calculations, and flag them to an operator. If facial recognition software is being used in Airports, I assure you it's considerably easier for vehicle recognition to be put in place on our roads - it only has to compare a few vehicles a few seconds apart.
A SPECS camera is a video camera, yes, but that doesn't mean it is recording constantly. All it has to do is identify each plate as it comes through, and record the registration on the system at that point. It doesn't need to have an actual picture - although in fairness it probably *will* take a picture at each set of cameras, for the purposes of producing evidence for a conviction later on.
In terms of the AI...now, I am not quite so sure that this will be how it works...
Just to give background, I work in IT & have done for about 6 years now, but my limit of AI knowledge is what I learnt at uni - so by no means an expert, but a little knowledge. Anyway, what I am thinking is that, taking your facial recognition example, this should be based on a 'template' of a face - i.e. the AI scans each frame looking for areas that match the template with a certain confidence level (throw a bit of statistics in there for good measure eh).
Now applying that to the ANPR-style system, it has to recognise what it's looking at in some form - it can't just say "oh, moving pixels, must be a vehicle" - I suspect it's actually very difficult to identify things when, crucially, you don't know what you're looking for. Number plates follow a certain 'template' so can use a system similar to the one I described for facial recognition.
The AI will never be able to say 100% between 2 frames that it is the same vehicle, as the pixels involved will (for all intents and purposes) always be different to some degree. It will give an answer in terms of confidence levels.
Basically I am saying that I think the recognition of an arbitrary object is very difficult and unlikely to be something it can do. If it had a template, that would be a different matter, but it would have to be a very generic template to match a bike, a car as it has to match all bikes, cars.
The SPECS system doesn't necessarily come into effect here at all... it's the operator that makes the call of compiling the video evidence from points A and B, the knowledge of distance X between them, and time Y to travel between the two, and finally Z, the speed that vehicle was doing. Some more footage to identify the vehicle or driver further... PCN on your doorstep.
Now this does indeed make sense...but depends on the system alerting an operator that there is 'something' to look at (see recognition, above) and the recording of said 'something' (again see above).
I get the feeling we need someone who works in AI recognition algorithms (as opposed to other types of AI that are not relevant) or similar to answer this :D but a good discussion about the algorithms and architecture behind the systems, for certain. :thumleft:

I work in IT too, and it's not quite done like that. The simplest way to acheive the aim, is to record video. However, when I say "record" I mean stream. Esentially, there is a process watching the stream, comparing each frame to the next. If the frame changes (ie, there's movement) significantly, the image of that single frame is passed to another process (which then grabs registration details - more in a minute).

You're dead right. The 2nd process in the system looks for something that resembles a numberplate (either white or yellow rectangle/square with black text). Then it performs some image processing (tidying up/housekeeping). Next it passes it through what is essentially an OCR process.
However, if that OCR process fails, the image is automatically forwarded to an operator for manual verification.
Imagine how many manual verifications are required, and it's easy to see why one officer recently told me that the camera operators near me have a habbit of just clearing the prompt without bothering to look at it in any detail.
Having an incorrectly sized plate, or the wrong font (some illegal fonts are recognised) is enough to fail OCR in an ANPR system.
There's no such thing in ANPR as confidence levels, if the OCR gets the same text, it's the same vehicle, if it doesn't get anything that matches numberplate format text (eg, letter, 3 numbers, space, 3 letters for a modern car) it gives the image to an operator.

:smt026That would be me, well, in the past, not now.
The above is the reason that obscuring your plate by any means (for example, being close to the vehicle in front) means the automated processing fails. It's assumed that you are the vehicle in front of you. Since they have the registration plate of the vehicle in front of you, if the were speeding, they get a fine. If you were, well, you're just never recorded leaving the second camera. So they have no proof that you were speeding.
EDIT: Sit too close to the vehicle in front, and *if* the vehicle you "hide" behind speeds - or the processing fails because they have a fancy font etc, the image will be flagged up to an operator. If that operator is a jobsworth, they can search the system for previously recorded pictures, compare timestamps, and if they have your plate from any image, send a fine.

Interesting, thanks for that Baph - I've always had an interest in AI, never really done much with it though.
Just one clarification re: the confidence levels - I was thinking about comparing 2 pictures, as you have mentioned it's done as a separate process once a registration has been identified in the picture. I guess the confidence level part (in the way I meant it) would come into play in the identification of the text, in this case I guess the OCR process compares the picture to stored images of letters & numbers - the confidence level would be related to the fact that the text in the picture is unlikely to match the stored images pixel-for-pixel, so a confidence level so some kind must be used. That's getting into the OCR algorithm, I guess.
So does that mean if you have a 'three' line number plate the ANPR could fail to pick it up.

Just to let you all know. Down on the A38 near Plymouth they have the cameras as you leave the speed restriction facing towards the rear of the vehicle. They may be trialling it down here or they may be doing this everywhere so don't take anything for granted.

That's getting into the OCR algorithm, I guess.
The output of the OCR process, esentially, just contains text, or it doesn't contain text. You have to remember that these OCR processes are far superior to the ones used on handheld scanners in the early 90's. :lol:
I suppose there is some form of "confidence/guess work" involved in OCR, but due to the image manipulation in stage 2 (which includes a conversion to greyscale amongst a myriad of other things), so long as the 2nd stage has locked on to a numberplate, the OCR rarely fails (on a legal plate). It's a similar grade of OCR used in the banking industry, only they use a stanardised font & scan a lot closer to the paper.
If for some reason, the OCR reads a plate as (for example) "A123 BC*" - it would recognise it's not a legal plate, and forward to an operator.
So does that mean if you have a 'three' line number plate the ANPR could fail to pick it up.
If it's three lines squeezed into the legal dimensions of a standard two line plate, the image would be given to an operator. If no plate is detected, the image would be given to an operator. Now you start to see why they get so many manual verifications.
If you have a small plate, it would assume no plate in the image, but the still frame difference is sufficient when you pass to take 1 frame of you on the bike, and forward to the operator for "missing registration."
If you have a standard size, but illegal font, you'd get as far as stage 2, then the image would be passed to an operator.
I only wondered as if you bike is registered before Sept 2001 then you can have a legal 3 line plate, like this -
| Y |
|123|
|ABC|

I am guessing that is for ANPR, rather than the SPECS stuff - would there not be an awful lot of bikes & foreign plates (does it read foreign plates?) causing many alerts? Compared to ANPR where it is set up for a short period only, and a high level of monitoring might be acceptable (ish)?

Yup, all of the previously posted information relates to ANPR's specifically. However, it'd be silly to design a whole new system, when they have one that can be adapted as needed, for less money.
Oh wait, forgot who we were talking about there. :rolleyes:
As for foreign plates, tricky one really. I suspect it would fail automated validation, and be flagged up to an operator. But then, real police officers generally don't issue tickets for foreigners (re: a recent BBC1 programme).
PS. ANPR has a static setup all along the A55, it's always there.

Just to let you all know. Down on the A38 near Plymouth they have the cameras as you leave the speed restriction facing towards the rear of the vehicle. They may be trialling it down here or they may be doing this everywhere so don't take anything for granted.

I went through those today, and indeedy, there are 2 cameras on each carraigeway (its a dualie), one forward facing and one rear...
Thing is - do these cameras only 'look' at one lane? If so, how would the above work? - 1 forward facing and rear facing into 1 lane only? - or forward facing for lane 1 and rear for lane 2?

Traditionally, you needed 1 camera per lane. However, there's nothing to stop you splitting one image in half. Subject to the image being of good enough quality (and these are damn expensive cameras that we're talking about! Last one I saw was £15,000, I kid you not! :shock: - it was a highways camera, 3D rotation, zoom, night vision capability etc etc)

I asked my dealer this when I picked up me new bike. He told me that a customer of theirs regularly sped through the average speed cameras on the M25 but the police then used the traffic monitoring cameras to get his plate. As he already had points and convictions etc. he went to court, they crushed the Busa he rode and he served time - we are talking silly speeds here though. The guy obviously has more money then sense though as the day after he got his licence back he went straight back to the Suzuki dealer and bought a new Busa.
