Seen a speed activated traffic light?

Don't need them in the UAE. Speed through traffic lights they arrest you and execute you the following Monday.

Isn't the penalty for mocking them the same?

Wouldn't know, only been here 40 years.
People that have never been know more..........or perhaps they read The Daily Mail.

We don't have them in Wales the man person walking in front with the red flag sets the speed

They had linked lights that do the same thing on the A4 west of Slough for 50 years or more. Get through the first and maintain a steady 30 and do you get through them all. Do over 30 and you will get stopped at every set of lights. Not been that way for ten years or so, but it definitely kept speed down. I guess there are about 15 to 20 sets of lights on the sequence.

They did that 60 years ago

Can't say I have noticed them, but the 'speed information' ones are anything but accurate, travelling at 20MPH and one near us is flashing to 30 and slow down, it is annoying.

The one that always seems to do this is on the old Hedon Road at the junction of Wyke Street

Sounds like they are too near the traffic lights, defeats the purpose.

I think the speed sensor on this one is on the top of the lights. The lights have little traffic coming off the side street, T junction, by comparison to the main road and they do go to red when there is no traffic waiting to come out if a vehicle goes through at 30 or over from my many years of observation

I have distant memories of the Mancunican way in Manchester being opened with traffic flow controlled by speed sensed traffic lights. It was a challenge for the locals to try and catch every light on green.

Not seen in real life yet but a great idea....

Speed activated speed bump. Obey the speed and no 'bump'.

Very sensible solution to keeping average speeds down.

We have them in Hull. The speeding car sets it to red as they get through leaving us behind to stop and I’m sure one is actually set at below 30mph

Where are those?
I'm aware of the fixed penalty lights at the junction of Mount Pleasant and Holderness Road, but not of any that are activated by speed without issuing a fixed penalty.

That's been like that since they built the dual carriageway, and it always annoyed me, especially when driving to and from work in the early or late hours, when there was no other traffic about. But I never gave it a thought that they were related to speed; I always thought they had never been set right in the first place.
Well, every day is a school day!

I wondered how many speed activated traffic lights there are about? I've only seen one on the A75 between Castle Douglas and Dumfries. If you've not seen one, they have a speed detector, a bit like the ones that give a smiley face if you're below the limit, connected to a set of lights a bit further down the road. If you're over 30 mph (on these ones) the lights go red.

Hi Whippet93:
Very common here in Portugal going through villages on major routes,. There are plenty of signs to say " This is a speed controled area " and devices set up just before the area to gauge speeds of entry.
It WORKS... If you do go in " Hot " you get stopped and sit there. You learn......PLUS.... you get NO points on your licence for that .
They are/were hot on not stopping at junctions where required and pedestrians can just walk up to a zebra cossing and cross. There are random checks anywhere anytime and i am led to believe,the GNR can access the Toll outfit with your number,to see if you have any outstanding tolls. Yes... Portugal and joined'y up writing......................... LOVIN' IT.

Many towns in Galicia, northern Spain, have them too.

Not just better environmentally, better financially, as less braking means your brakes last longer, steady speed uses less fuel than accelerate, brake, accelerate brake.

I agree, I forget which state it is out in the Mid West that on major roads has a warning light a good distance before traffic lights to alert you that the lights are about to turn red. Their accuracy is great and I always know if I speed up a bit I can get over the green or what I always do is ease off and coast gently up to the line with very little braking. It is so much better than approaching a light at road speed and having to suddenly brake with an 8m trailer on the back.

When I took my tow vehicle in for a service last week they actually asked me if I never use the brakes because they’d just measured the pads and stated they were the same as last time, almost 10,000 miles prior. I’m not sure about the accuracy of their measurements but I’m happy to not be replacing pads or disks anytime soon.

I think it was the approach road to the Mancunian Way, Upper Brook Street (A34) behind the Uni, there was not only a “Green Flow” traffic light system, but also a “tidal flow” lane which was the middle lane of five.
It was controlled by overhead indicators to allow traffic towards town in the morning, then away from town in the afternoon.
It was ahead of its time!
The locals were seriously challenged not only trying to catch the green tide, but also in deciding who had right of way in the centre lane
Certainly woke one up first thing in the morning

We have lots of them here in Lanzarote.
The speed detector is quite a way before the lights, so you don't get chance to brake quickly.

They're usually out in the villages.
