I suppose how far you draw the perimeter. Wasn't Edinburgh talking about blanket coverage the other day?

I do wish they would educate the fecking public, tell them trying to stop kissing cars.

On a typical weekday I'd imagine increasing the speed limit will actually bring down the average speed due to more wave affect braking and a bigger difference in speed between lorries and cars which will cause more accidents
Rubbish
Not saying this would happen but surely it's a bit more intricate than just saying "rubbish". Anyone know of of published studies on similar changes in other countries?

It's certainly not rubbish. The whole point of the variable speed limit on the M25 was that reducing the limit would increase traffic flow at peak times. It might work, too, if they ever actually got the limit set to the right thing at the right time. banghead

It's been in place on the Heathrow section of the M25 for about 15yrs, and I've never seen any signs of it working, or of being any practical use. The motorway there seems to go from flowing to jam in about 30 minutes every morning and evening. The managed thing there is useless, and pointless.

Yeah it doesn't work but I'm fairly convinced that's because it's poorly implemented rather than because the principle isn't sound.

It's a rubbish system made worse by those faceless wonders that run it, I've lost count of the number of times that you drive along there with a 50mph limit when it's clear.

Money, control and shouty people (both speed and environment related).
M60 implementation that's ongoing for the next 2+ years is an example of lots of money spent & plenty of misery to achieve little.
A friend of mine decided to go to the Trafford Centre for the sales after Christmas and spent seven hours on the M60 before managing to get out of the jam and come home.

Theoretically the smart motorway system will stop waves of traffic slowing and bunching up and will warn of dangers and congestion ahead, therefore making it safer to travel faster than you an on an ordinary motorway should the stretch you're on be clear enough.
Using it regularly, as I do, it won't do anything of the sort in reality smile. The problems of that stretch of road are down to piss-poor design and a lack of desire to solve that (e.g. Simister Island and the Eccles/Swinton interchanges). Nigh on 20 miles of 50 limits to protect the precious cones has done two parts of sweet FA to solve any of the issues so far.

The Trafford Centre stuff is as much down to the local roads as much as anything else.
It's useless in reality and the problem round the Trafford Centre is everybody heading to one junction. Get past the Trafford Centre and the motorway is empty.

However, the government wants pretty much every stretch of motorway from Manchester south to be a managed motorway. In that scenario I'd much rather have an 80mph limit than 70mph, though it's true they'll probably be flashing up random reduced limits all the time.

I saw a particularly amusing one on the M1 a year or so ago where the limit went NSL -> 60 -> 50 -> 40 -> 30 -> NSL through subsequent gantries and of course the last one had a speed camera on it. It was flashing pretty much every car. silly

Must admit I thought that as well. Seem to remember the Tories declaring the war on motorists was to end during the last election. Now we have extra cameras on motorways, no only for the so called managed sections, but will/are active when the the 70mph limit is active. Lots of dirty cars with ditto number plates to be popular I suspect.
That must be a record. Topgear on TV and within an hour someone repeating exactly what they've heard.

They do work, I did a journey on the M1 at 60 for ages out of London, but I realised if they lifted it and removed Hard Shoulder running suddenly we'd be stop starting because the traffic would be squeezed and affected by people trying to drive faster than the road allows.

Heathrow is a law unto itself, and I imagne no amount of "smart" motorway use will solve that.

Part of the problem are people who lane change, zoom down slip roads (J16 southbound is a favourite) and try to do 80 between the cameras then brake hard again when they come up to someones rear end.

From an article I saw recently in a daily newspaper (can't remember which one) regarding driving at speeds at which individual drivers are comfortable, not staring at a speedometer to comply with a penpusher-imposed limit:

Of course, it's too simplistic to believe that the higher the speed the worse the crash...

1) Studies by the German Transportation ministry have shown that when crossing a certain threshhold the brain function changes.
While people intensively use their cortex at lower speeds, more function goes to the limbic system at higher speeds. Which means that reaction/response times are shortened and driving becomes less tiring. They are therefore safer.

2) Driving on unrestricted Autobahns also means people develop a better understanding of their vehicle and its capabilities and limitations.

3) Death rates cannot be compared by country. The weather in countries like Spain, Italy and even Britain isn't as challenging as in Germany, were a severe winter makes accidents more likely.

So far it looks like driving in Germany is comparably safe as in other countries, despite the lack of a speed limit and despite adverse weather conditions.

Me neither.

I've been on the M42 countless mornings at 6am and seen the limit go down to 40 for no reason. Happens often.
isn't this because they track average speeds and at that time of the morning most traffic is lorries etc?

On a quiet motorway a low limit will follow a slow lorry all round the system. It's always happened with the ordinary advisory limits but it happens with the mandatory camera enforced limits now.

Come to Brighton then smile

Mind you, it's largely ignored by everyone, even the police.

(OK, it's not actually totally blanket, just most of the city and the major routes)

Someone needs to show the Green Party in Brighton this little bit of research. http://www.theaa.com/public_affairs/news/20mph-roa...

The M42 managed motorway works well IMO. I often traverse on a Friday afternoon rushhour and it was a nightmare. More often than not it is now smooth running. It's not perfect and some of the 60 limits are a bit keen in my opinion, but I'd sooner have it as it is now than before.

Yes, I was driving on the Autobahn earlier this week in a snowstorm. It was so bad the traffic slowed to 70mph.
