[#10199125]

anyone ever been done by one?

(specifically those temporary road works ones)

was just wondering if they actually worked as I was driving though one on the M23 last night keeping the needle on the required 50 and loads of people were zooming past me.

igoring the obvious twuntish behaviour but do they know something I don’t or are they just dumb?

Perhaps they were using the speed limit plus 10% plus 1 thingy and it just seemed they were going past faster than they were.

My wife attended a speed awareness course in the North East and there were people on the course who had been done by the average speed cameras on the A!.

I don't know if they work or not, I always stick to the limit or just under it.

You do see loads or people ignoring them though, makes me wonder if they understand the concept of;

a) speed limits

b) speed cameras

c) the word average

But hey, it's them that get caught and not me so who cares?

I've heard of people done by them, but think it's not so common. Mostly as the majority do tend to stick roughly the right speed, "on average".

Also, if traffic slows right down during it, you can then go over the limit. So long as the average is right 😉

Anyway, cop at speed awareness course told us the average speed cameras aren't used for revenue, with implication that Gatsos are. Though doesn't mean you can't get a fine from them. I guess he means the average ones are more lenient.

What he did say is the primary source of speed fines comes from mobile units, handheld guns etc. Which is how I got done and I think most on the course did also.

They can’t be clever avg speed cameras ie  do 100 miles, drive 90 miles at 5 mph and the last 10 miles silly fast?

it has to be the avg speed between 1 camera and the next which gives less opportunity to go quick

I stick to 54mph

I 've been past by a range rover sport doing over a ton the braking heavily for the cameras the booting it again on the  cambridge average speed cameras section.

Have you noticed how they aren’t taking them away after the roadworks have finished?

Wont be long before the whole motorway network is covered and they get switched back on permanently...

don't worry once self driving cars are on the road every car/bike/lorry will have a limiter.

I think they keep them on the motorways once the works have been completed for a period of time, just to educate drivers that speeding isn't clever nor a cock waving contest.

You will of course always come across the truck driver up your chuff intimidating you through average speed camera sections, it's ingrained in them that they're above any law in the UK and feel all macho because they're 1.4mm from your bumper.

Of course slam braking whilst in front of them isn't clever either, but slowing down in a progressive manner certainly makes them aware that you are not going to be intimidated and they normally overtake or undertake.. which is fine by me. I'm not in the slightest concerned about those idiots.

I'm more concerned by the morons who overtake you then pull in in front of you giving no warning, no indications and 2mm's from your bumper.. all so they can exit left because they've lost the concept of lane filtering before the junction appears.

Generally though, say 80% of the time, most people are indeed normal and drive correctly through them. Obviously not all of us are morons, most people actually do care about our driving ability and consideration for other road users...

Exceptions to that, yes.. there will always be exceptions.

The M25 ave cameras during congestion times work, two colleagues have been done on the western section (heathrow) doing 50 in a red limited 40.

Don't tease, that would be bliss.

Or their speedo is calibrated more accurately than a passenger car?

Average speed cameras have transformed the A9.   I used to drive Elgin to Perth regularly and there was almost always a "moment" every trip.  Did it again this last summer - firts time in about 8 years..everyone was much better behaved.

They certainly do the ones on the A1 mentioned above got hundreds, then there was a balls up so some had their fines cancelled.

On the M6 and coming soon to the M60 smart section. They have a camera mounted to the side of the pole that is perminately on and set at 70.  https://www.speedcamerasuk.com/hadecs-3.htm

How is that relevant? Is tailgating ok if you have a more accurate speedo?

Just because the car in front is slower than the limit doesn't mean you can sit on their tail.

Never been done by an average speed camera because I don't drive like a dick.

I think average speed cameras are great and should be installed nationwide, they have transformed the A9 and A90 into roads that are pleasant to drive.

Insightful, from Klunk's link

What police say about speed cameras on A14
PC Jon Morris, casualty reduction officer at Cambridgeshire Constabulary, said: “The speed limits on the A14 are in place for safety reasons and I’d urge all road users to adhere to them.
"Those who choose to ignore the speed limits will face prosecution and more importantly put people’s safety at risk.”

Er, if I am not mistaken, that applies to all speed limits/cameras, like.

Really ? The A9 is now tedious and boring with people doing dangerous overtakes.

Back in the day you could easily drive at 70+ mph without it being dangerous

A few years back it was decided by traffic Wales at least (i assume it was a decision from on high so UK wide but never saw anything outside of Wales personally) that all new gantries should have cameras and they should be both fixed and average to prevent surfing. If that ever made it beyond tendering i don't know - I'd imagine it got dropped once pricing came back in, but it was certainly present on specs for a couple of years.

Personally I'm all for cameras everywhere, unsignposted and rigidly fixed at the limit but it'll never happen.

I always assumed the reason trucks seem to speed through with relative impunity was because they were generally limited to 56mph,

56 < ([50 + 10%] + 2)

So trucks could speed through at their normal speed without worrying.

The M25 ave cameras during congestion times work, two colleagues have been done on the western section (heathrow) doing 50 in a red limited 40.

Those aren't average cameras, they're fixed cameras with variable limits, the nearest average bit I think is the M25/M3 junction with a permanent 50 limit and average speed cameras.

Have you noticed how they aren’t taking them away after the roadworks have finished?

The one's that aren't on have signs saying "camera not in use".  AFAIK driving Manchester to London a lot over the summer the ones on the M6 and M4 were all off outside the roadworks.  They're presumably left up as they're upgrading them to managed/smart motorways so keep revisiting sections to do work.

My favorites are the signs which read "sign not in use"

I try not to think about those too much, it could break the space/time continuum (which could really stuff up my average speed through the roadworks).

They have left them on the M3 after the M25 going south. This is, IMO, a good thing as 8 lanes merging is a bit of a choke point.

A9 boring and tedious ? Naw as a regular user it's meant that at the speed limit your no longer the slowest thing on the road , the dualer sections are no longer like wacky races with people doing 100+ to get past as many folk as possible .

They also average camera's the a92 south which has made it a plesent drive at rush hour again at 70 you didn't dare pull out to pass a truck previously for fear of an Audi /BMW barrelling up the back of you at 110. It also means that bottle necks at Charleston and bridge of Dee are much less congested than previous as you don't have everyone that left Dundee between 6.30 and 7.30 all arriving at 8am trying to negotiate it.

Stick the cruise control on kick back and relax.

Going north up the a92 is still mental with folk "making progress" at everyone's expense. There's been a high number of accidents this week alone.

Proofs in the pudding with the accident statistics.

Cougar, no they're not average speed camera's. But once the average ones switch off, the ones behind the speed sign, these stay on. In case anyone fancied flooring it.

Ooh, I'm really sorry for explaining their reasoning without condoning their actions. Maybe you should take a teaspoon of civility while I take my common sense eh.

The A9 has been greatly improved, and journey times cut, since the cameras were introduced. The number of times I see selfish prats doing their stupid overtaking manoeuvres has reduced significantly.

The A9 is a total ballache now - admittedly their were complete idiots before, but now is almost as bad as everyone is constantly watching speed and not Road (unless they have cruise control, but even that appears to be constantly checked).

Awful Road to drive now, I'm not a fast driver but I do think the danger has been moved from fast idiots to the constant eye on the speedo and not the road.

They do work between 2 cameras, don't they, so 4 cameras...between cam 1 and 2, then 3 and 4 or between 1 and 2, 2 and 3 and 3 and 4 or between 1 and 4?

They're all members of the Schrodinger clan.

ASCs have  reduced accidents and fatalities on the A9.

As a regular A9 user, I’d agree with gwaelod and trailrat, (and scotroutes), since the cameras went on the number of speeding drivers has reduced noticeably, i used to have, on average, one serious moment on every trip to snekkie, but nowadays such events have become a rarity.

average speed cameras work.

Older ones ran in pairs, so it could be lane 1 of batch 1 paired with lane 2 of batch 3.  Think the modern ones are a bit smarter so just check your speed between any 2 fixed points.

56 < ([50 + 10%] + 2)

10%+2 is ACPO guidelines, ie a police recommendation.  It's not law anywhere, you could theoretically get done for doing 51mph (though you'd have to be pretty unlucky).

I always thought the 56mph thing was related to fuel economy?

All of the above, though they don't cover the dualled sections and the two at Tomatin/Daviot always operate as a pair.

Ok, ta. I'll stick to my normal then...cruise control at speed limit (which is 2mph below according to GPS - which isn't 100% accurate but seems to be better than speedo (according to those signs that show your speed, GPS is the same, speedo 2mph faster) and drive.

Speeding motorists have reduced but those not watching speed and either braking hard then slowing down a lot or just 'crawling' have increased.

Once every car is "connected" they can do away with cameras  Surprised they aren't already fining people based on Google Maps and Waze use.

I used the A9 some weeks ago & was impressed with how quickly & effortlessly I covered a lot of miles. Constantly speeding up & slowing down as traffic bunches is a pain. Stick the cruise control on chill out a bit.

Seems like a sure-fire way of getting people to not use those apps.  It's not like there's a shortage of alternatives.

Seriously ??

You admitted to deliberately slowing down to cause 30T trucks inches behind you behind you to slow down and driving in the wrong lane?

All legalities aside and the laws you are brewing by doing this it doesn't sound anything close to common sense.

FWIW those roadside displays that show average time to destination/junction are calculated using Bluetooth ID. ....

Yeah seriously.

No reason for a truck to be up yer arse is there ?

Unless you like it that way.

So, instead of being shoved from behind or flashed for doing the speed limit.. slow down a bit over a section of say 100mtrs and they get the picture that you aren’t going to be intimidated and either overtake or undertake.

I do it yes, I’ll continue to do it because I value MY life and don’t want nor need to be intimidated on the public highway by morons who think they own the road.

Happy to share that with you.

If you feel any different then by golly speed all you like.
