Average Speed Cameras
-
Hi people. Just been reading up on average speed cameras. What suprises me is the number of people I see fly past me on the motorway when we're in a area controlled by them when i'm doing dead on the speed limit. Is there something i'm missing, like does it take a snapshot at each camera and use those to compute the average snapshot speed? or are all these people waking up to nasty fines and points on their licences?
Going slightly off-topic here; I'm used to seeing the normal Gatso cameras with 10 yards or so of white markings on the road, but over the past year or so I see front facing cameras with 3 lines painted on the road covering about 1 foot. Are these actually speed cameras or are they ANPR checks for road tax etc??
It definitely isn't definatley

GPS actually give a lower (more accurate) reading that speedos, which are designed to over-estimate.

Doh, That's what I meant to say :zzz: You go faster for the same indicated speed

They're forward facing speed cameras I believe.

Probably positioned so they can take a photo of the driver.

Which, under data protection law means they cannot be used in evidence. (In fact no camera evidience is admissible as it is digital, which is why you have to sign the back of the NIP form they send you, that is what they use to prosecute.) Strange thing law, especially when it is designed by unelected morons in foreign countries.

Ones in the UK use number plate recognition and average over (I think) at least three cameras. This means it's no good switching lanes which some idiots try. I've seen average speed limits around roadworks which is a very good use of them BTW, over 100 motorway mantenance workers are killed every year by motorists. Elaine :rose:

Here it depends on what car your driving ;P No not really, the fact is tho the newer the car the closer to your actual speed is displayed, my car has the 10% rule (it says I'm driving 50 while I'm actually doing 34 45). The camera's don't take that 10% into account, only the +3mph (or 5km/h), at least for as far as I know. I do know that some camera's (at intersections with lights) will only register when your driving thru a red light. Also if your speeding and the picture shows that your where breaking at the time (so your break lights are on) they will add 5km/h to the speed registered. (at least here they do) [edit] corrected typo [/edit]

You seem to know an awful lot about this subject... :^)

The quality and detail of your question reflects on the effectiveness of the help you are likely to get. Show formatted code inside PRE tags, and give clear symptoms when describing a problem.

Surely more then 3 cameras give better accuracy? If averages are taken between pairs of cameras, and then an average of those values is taken again then you get a more accurate result as exact positioning of the cameras is less relevant. Where am I wrong?

Connections, connections ;P No I'v had 2 or 3 tickets so far ( only 1 for speeding tho). But half of my family works for different government agency's and a friend is a cop (o sorry police agent) so from time to time I hear some things. :)

In your assumption that the law is interested in accuracy, instead of just having enough evidence - that you'd find it almost impossible to dispute - to take your money from you ;)

I don't think you're missing anything - but that's why I also stick to the limit through average cameras! However - I stick to the limit as measured by a) my GPS device, and b) the average speed functionality in my car's trip computer - those two agree and indicate a higher speed (by 3-4 mph) than the speedometer, so that's what I stick to. As I've not been pinged in roadworks (touch wood), I think my strategy is valid.
