Good idea.

Should also be based on speed. The faster you approach, the longer the extra delay.

My sister, who lives in India, sent me the link. I wondered if it might be an elaborate joke, but she insists it isn't. There's a better explanation in this link:

There used to be a system in parts of Germany - Gruene Welle - which displayed the speed to maintain so that you met green lights all the way. Boy racers would get in front of the greens and of course meet the red; those driving as advised would catch them up and sail past......

Portugal has speed cameras incorporated into pedestrian into crossings - you speed they turn red even if no one is waiting to cross.

" Should also be based on speed. The faster you approach ..."

Like the one in Slough in the - IIRC - 1970's, (and may be still there) on the A4 past the Trading Estate, limit was 30mph so if you could reign yourself back on what is a longish straight road it allowed you to sail along.

I just put "Gruene Welle" into Wiki to see if it pre-dated Sluff, but wasn't recognised - maybe spelling ?, whatever it's a good idea, thought of long ago, and with modern technology (you can't beat an 'ology' !) should be simple to implement Shirley ?

Of course if people don't speed, fines drop orf so .....

In the 70s/80s you could go down London's Marylebone Road without stopping if you hit the first light as it went green and then kept to the speed limit. I knew a traffic expert at the time and he said it was set up that way.

Try Grüne Welle - I used the spelling without umlaut because I couldn't face digging the ü out of my keyboard!

Presumably if set up for 30mph it would also work at 60mph or 90 or 120...

" Try Grüne Welle "

Yes that works thanks, and very interesting, but why does this bit - (copied from Wiki) not surprise me !!

".. In the UK, in 2009, it was revealed that the Department for Transport had previously discouraged green waves as they reduced fuel usage, and thus less revenue was raised from fuel taxes..."

My fastest time (and most economical mpg) journey from Reading area to Manchester area was a couple of years ago when the majority of the motorway sections were limited to 50mph due roadworks - and it was crowded.

Everyday mpg from my diesel car at the time was 44+, that journey usually took mpg up to 48+, this time i recorded 58+ Figures taken from a physical brim to brim, couldn't believe them, so re-checked twice ! From their point of view DfT might have a point ?

If you scrolled down the video was pretty good, even after people figured out what was happening they still tooted their horn.

Cynical moi often wonders why so many roundabouts are "landscaped" and "pruned" in such a way (i.e. not at all) as to make it nigh on impossible to see if there's any traffic already going round without actually stopping on the line. It utterly defeats the purpose of a roundabout in the first place, but of course all the unnecessary braking increases fuel consumption.
And don't get me started on traffic lights! Most of the ones on major roads where I live default to flashing amber at night time and off peak hours, so it's "proceed with caution" and mostly common sense takes over.
