‘Smart’ motorways
I’ve been saying for years these things are ducking dangerous, especially on the m25 where you’ve got four lanes and lots of cars on the road. It ends up like wacky races and lane discipline goes out the window, and you’re having to concentrate on the fucking gangways whilst manouvering in busy traffic!

The other day in a very short section of the m4 it went 50-60-40 for no apparent reason

Re: ‘Smart’ motorways
agree with others - almost all problems on motorways are caused by middle lane drivers. Should get points for it

There's a few on here, comma being one, that I'd place a significant amount of money on being middle lane drivers.

Re: ‘Smart’ motorways
Frequently when on the M2 I find myself undertaking some cuntshovel doing 55 in lane 3 of 4. I’ll be fucked if I’m moving over 3 lanes to overtake the twats. Just seems mental so I undertake them even though I hate undertaking but what are you going to do short of belt fed grenade launchers being retro fitted to the van?

I’d say 9 times out of 10 it’s Africans driving like it as well.

Re: ‘Smart’ motorways
The main problem with these "Smart Motorways" are the thickos still want to sit in lanes 2-3 and do 50 mph, even when the all clear signs are on. They hog those lanes causing the normal drivers to have to either move out into the 4th lane, or just go there inside doing the wanker sign at them as you pass!!! There seems to be a lot of silver Primus drivers who love to sit in the middle outside lane pooderling!!! Uber drivers??

Interesting stuff that. Could explain why the M6 16-19 seemed to run smoother while it was being upgraded (3 narrow 50mph lanes) than it does now its been fully upgraded. Every cunt knew it was 50mph so just drove accordingly. Now its "smart" all the limit changes just seem to cause more problems.

Re: ‘Smart’ motorways
There’s a simple system that would make motorways much more efficient and pleasant to drive. Anybody hogging lanes and not using them to overtake gets picked up on camera and receives a warning letter to sort their driving out and stick to the SLOW lane. If they offend again is removed from them and crushed at their expense and with them being forced to watch. If they buy a new car and repeat the offence then their car is removed from them and crushed at their expense with them inside.

Yeah, that's the essence.

Same principle applies for road traffic; the "block" is the stopping distance of the vehicle at a given speed under given environmental conditions, which fully supports your thesis on road (network) capacity (The OU has a similar module).

Cocooned in a car, people don't realise how the speed they are doing relates in the real world to stopping distance until they find they've run out of room to stop.

The only real advance to safety in this area was a facility that prevented traffic from getting closer to that in front at any given speed.

"Cutting in" could quickly be stopped by having an internet enabled dash-cam that was triggered to send a photograph to the authorities on such an event. Points on the licence is a great attention-getter.

Re: ‘Smart’ motorways
Mike - I thought "block" was in place for almost as long as railways have been going.

In the old days, it was one train-set per block, with "block" being a fixed definition/ section of track. No train can enter the block until the one ahead of it has moved into the subsequent block.

Whereas these days, with computers & automatic signalling, there's "dynamic block" where the "block" is in essence a minimum spacing, the length/ size of which takes into account operating speeds and track characteristics/ conditions, etc

Re: ‘Smart’ motorways
A similar strategy has been applied to the railways for as long as I can recall - "Blocking" I think they call it, out of deference to one of our more prolific, albeit sporadic, posters.

Re: ‘Smart’ motorways
Back in 1992, I did my MSc Dissertation on motorway traffic control strategies, with Variable Speed Limits being one of the two I investigated in detail.

Basically, as vehicles travel faster they tend to get longer distances between them, which means above certain speeds (50mph give-or-take) the higher the speed the lower the effective capacity of the road becomes. As such, when traffic is above a certain level - counter-intuitive though it does appear - lowering the speed limit can increase a road's capacity (and keep the average of speed of vehicles higher). Basically, it reduces the likelihood of a road going over capacity in a given section which then results in the speed collapsing much lower than that which would be obtained with a slower (observed) speed limit in the first place.

Of course, the key issues which I couldn't take into consideration using computing power for traffic simulation back in 1992 was the impact of some drivers deciding that the reduced speed limit didn't apply to them and/or adopting suddenly more aggressive lane-changing/ gap acceptance behaviour and/or deciding to use the hard shoulder when not supposed to.

(Nor did I consider use of the hard shoulder as a legitimate, narrower lane - as that would also have required a whole load more issues to be considered/ separate rules & behavioural parameters to be run in tandem with those for ordinary lanes.)

Re: ‘Smart’ motorways
I would say they were limiters rather than targets mike

Mike Oxsaw 4:36 Sun Oct 27
Re: ‘Smart’ motorways
Those black numbers in a white circle with a red ring around it are a limit, not a target - as hard a concept to grasp/accept that may be to some.

In other words, individuals CAN choose to travel at any speed UP TO that value, not that everyone MUST travel at the figure shown.

Inconvenient, is it? Fly next time you self-centred cunt.

Re: ‘Smart’ motorways
But if you leave a proper distance, them chevron thingys are supposed to be the safe distance, someone always nips in the gap, eventually you would be going backwards.

Re: ‘Smart’ motorways
Sometimes changing lane is almost unavoidable if the driver in front slams on.

Surely that means you are too close to the car in front?

Re: ‘Smart’ motorways
....or because of a sudden unexpected change of speed limit.

Lets be honest, we're human beings. No one is going to drive perfectly 100% of the time. Saying "everything would work well if everyone drove perfectly" may be true but it isn't realistic and doesn't stop the fact that smart motorways add to existing problems as well as create new ones.

And dunno about you but I'd rather be stuck in traffic than dead.

ray winstone 3:28 Fri Oct 25
Re: ‘Smart’ motorways
mim, the reason why the driver in front has ‘slammed on’ is because some cunt half a mile up the road has changed lanes!

Re: ‘Smart’ motorways
There are many reasons why someone might stop or slow suddenly. Leave room and stop driving like cunts.
