Full Version: M4 /M25 into London Average Speed Camera
FightBack Forums > Queries > Technical Discussion of Enforcement Devices

Dear all,

On the way to London today, on the M4 off from Junction 15 on the M25, I noticed what looked like average speed cameras (they were yellow cameras) periodically placed every few hundred meters or so. The cameras were NOT forward facing - they only capture the back of your car.
If you are familiar with this stretch, I am sure you are aware of the GATSO speed camera placements on the 60mph zone through to the 40mph zone. Waze successfully picked up the GATSO speed cameras, as it usually does, however there was no mention of average speed check zone, nor were there signs of an average speed check area. The only signs were the speed limits and the occasional "police enforcement cameras"

A few questions I have:
1. Are these cameras average speed check cameras?
2. Why are there no signs indicating average speed check if the area is?
3. Are all average speed cameras forward facing?
4. What are those cameras? They were yellow, so cannot be traffic control cameras.

Regards
BaggieBoy
There are currently no active average speed cameras on that stretch of the M4, but perhaps they have been placed there recently in preparation for some upcoming roadworks. The cameras can be set to be either front or rear facing, it makes no difference to the operation.

Doing a quick search shows that the J3-J12 smart motorway upgrade is due to start this month, so it's highly likely these new cameras are being sited to enforce the reduced speed limit until the completion in 2022. http://roads.highways.gov.uk/projects/m4-j...smart-motorway/

Cameras like these?



They are Siemens Safezone ones, very popular and very lucrative in London. Whenever I drive down the A40 Westway they seem to be getting plenty of custom.

They do not look much like speed cameras although will have Average Speed Camera signs on before they go live. One would imagine they are specified for the Highways Agency by the Met police to save having separate back office systems.

It was only a matter of time before the wet film Gatsos were replaced on the M4, they are old technology now although still widely used.

Thank you for your reply.

Based your message, assuming they will be turned on soon, will there be signs stating average speed check camera zones? And if they are not turned on/enforcable, why are there no "Camera not in use signs" posted?

And are you 100% sure these cameras are not turned on?

In that case they are just standard temporary SPECs cameras as BaggieBoy says for roadworks. They are often installed some way in advance but normally they put "Camera not in use" signs up too. They can enforce in either direction, but if they are rear facing they can catch motorbikes too.

They will have standard temporary "Average speed check" roadworks signs once the cones go out.

There is no requirement for signs to warn of speed cameras, either active or not, so it's rather pointless to speculate on what the authorities may do, or why.

I travel frequently from South Wales to Heathrow so will have to start leaving 30 mins+ earlier soon then...

Come the Autumn there will be roadworks all the way from M4 J12 (west of Reading) to J3

That's going to be chaos!
