Average Speed Between Two Cameras
Discussion

Almost correct apart from " two images taken two minutes apart ". The time between the images depends on your speed.
Image 1 taken at 12:32 by camera A. Image 2 captured an image at 12:34 by camera B further down the road.
Doesn't that make it an average, or estimated speed rather than an actual speed?

It would be great if all images were taken 2 minutes apart. You could charge past camera A at 150mph, when camera B took it's image 2 mins later you'd be long gone!!!

It's similar to all speed mesauremnts taken (done between two fixed points) but these are just further apartIn many ways this works out better as you could be doing significantly above the limit, then brake and do significantly below the limit and only be punished for being a few mph over, rather than the max speed you hit.

I think the times above are missing their seconds.

First image is of vehicle in L3 overtaking; second shows it in L2.

The interesting bit is this is 2 cameras on a road with 2 major junctions between them and seemingly no limit to how far apart the start and stop cameras can be, catching speeders is as easy as shooting fish in a barrel.
Is this how speeding ends or prosecutions shoot through the roof exponentially.

If that's the system,
I have heard of some being changed to be both A-B and In camera view (New dual cameras) so it could be either in some areas.
There's a sign underneath the camera saying "average speed check" and a speed limit sign for 40mph, so it seems pretty clear these are just the bog standard average speed cameras, nothing new.I have heard of some being changed to be both A-B and In camera view (New dual cameras) so it could be either in some areas.

Had you been 2.3 seconds later at the 2nd camera, you probably wouldn't have been contacted (could be slightly +/- 2.3s depending on rounding errors).12:34:03

It may well be that average speed cameras are having a similar effect to the speed camera vans.

I might have this wrong so please feel free to correct me.
NIP for 46 in a 40.
Alleged speed recorded between two cameras. Two images taken two minutes apart. The 'recorded' speed is based on the time it takes to get from camera A to camera B?
and your problem is?........NIP for 46 in a 40.
