A316 average speed cameras go live on Monday 13th June
Article by: Darren Griffin
Date: 9 Jun 2016
The installation of new average speed cameras on the A316 in London were completed last month. The new cameras will be activated on Monday 13th June.
The The Home Office approved Siemens SafeZone cameras are being installed as part of a TfL contract to replace existing wet film cameras on four selected routes. The A40 went live in October last year and the A406 and A2 will be activated later this summer.
The system operates 24/7 in all weather conditions with each camera able to monitor two lanes of traffic and can identify the registration, make, model and colour of vehicles in all light conditions with average speed calculated over a measured distance within the speed enforcement zone.

We have them in the submission map but the last time I looked they hadn't been activated so not in the download yet.
Unfortunately decorating has got in the way of me getting out there to verify them.
Given they are to be activated can we activate them pending verification?

Yes and no... there's a mixture of speeds on the unverified ones - some at 50, some at 40. I'm guessing in the next few days we'll have more submissions that will help verifiy the speed at each location - there are also quite a lot of 'single' submissions with no other submissions nearby. I'd rather be slightly later with accurate locations and speeds than have loads of misinformation...

Sound to me like K desperately wants to take a drive around the 316.

Fair enough.
I reckon I'll be down there later next week or the week after.

Pity they couldn't spend the money repairing the roads, rather than wasting it on these infernal things.

1) I've noticed that the "tick" roadmarking that gives the datum point for these new cameras can be different for different locations. Usually it's a plain "tick", but for instance the last one going westbound out of London just before the start of the M3 has a double line added - is that to indicate it's the last camera, I wonder? If so, it's a useful visual clue. I haven't clocked the other ones yet.
2) The A316 is a mish-mash of 50, 40 and 30 mph zones, so I can't work out how They are going to measure the averages. The fact that the eastbound 30 mph monitron camera remains in situ is interesting - does it suggest the 30 zone is not part of the scheme? I wonder, in fact, if the A316 scheme is actually a collection of individual pairs of cameras, and not an overall end-to-end (Hogarth-M3) scheme? As with other schemes, this one cannot "see" vehicles joining the A316, speeding as much as they like and leaving the A316 before the next camera, as I don't think the side roads are camera'd (is that a verb...?;)

My guess is that they are indeed programmed camera to camera. Like the A40 and A406 (western ave and north circular) there are loads of joining points.
Once you have passed one camera they know how long it takes to get to the next one, even when the speed changes mid cameras. Beat the time and get a prize in the post.
This week isn't looking good for a clear dashcam run, significant rain forecast every day so hopefully the week after.
From info supplied (by Spacedman) I'll join at the Costco roundabout at Sunbury and go all the way to Kew bridge. If there are loads of speed changes I'll probably have to do a return run to get all the speed signs recorded as well.
Once logged I can work out if the cameras are cleverly sited or whether we need some dummy entries if the limit changes mid camera pair.

Probably not. The apostrophe is miss-placed as it neither represents a possessive or an abbreviation (the only two times an apostrophe should be used). Having said that, I'm not too keen on camerad as a verb, as it seems much closer to German for surrender as seen in all the best WW11 films. But I suppose it amounts to pretty much the same thing really.
Re. change in speed limit. No problem. Take two cameras 2 miles apart. The first mile is (say) 30MPH which should take no less than 2 mins. The second mile is (say) 60MPH which should take no less than 1 min. Anyone who passes the second in less than three mins get's one of Kremmen's prizes in the post. And yes, I do realise that you could do the fist miie in 1 min as long as you take 2 mins for the second mile.
