[Closed] A9 average speed camera preparatory work starts today

That's why it's madness. You just can't make significant progress on roads like these without a really fast car and a deathwish, so why bother? Just relax.

Not being funny but, have you driven up there? I don't do it anything like as often as some on here, probably only about 20 times over the last few years so I'll bow to them if they disagree... but my experience is that yes, you often can make considerably better progress, safely, without either a really fast car or a deathwish. And you could do better still if other drivers were more considerate, without taking any risks (*). It's often a road of logjams rather than a road of constant traffic.

There's a lot of different things going on here so you don't have to disagree with everything else for a single point to be valid, but, I think it's basically a given that if safe overtaking is easier, then it reduces the amount of dangerous overtakes.

(* above and beyond the standard risks involved with being on the public highway, anyway)

[img] [/img]run a length of that up there would stop the overtaking

Molgrips, did you say you've never driven this road? It's perfectly possible to make decent progress on it provided you don't get caught in a 50 car tail back. Once one of that size formed you're pretty much stuck so, yes, you should sit back and relax a bit.

The problem is, some people seem to expect empty roads, and can't handle it when there's anything in front of them going less than 90mph. People are not rational - most don't think '55mph is fast enough, I'm happy'.

Nail on the head, you can't fix that. So it must be easier to fix the other problems, the triggers that cause the dangerous overtakes as you've just said you can't fix human behaviour.

How're you going to do that, short of dualling it all? Even at 50mph people get worked up into a homicidal rage, just look at the hatred for caravanners. So there'll still be death defying overtaking.

It is being duelled, though it won't be finished any time soon. 2025 is the target I think.

So what else do we do? Try and encourage caravans lorries to pull over and let some of the traffic past when the queue behind is huge? Increase the HGV limit? Enforce a minimum speed limit?

would certainly make sense if the limit was consistent for all vehicles. but then I've got stuck at 45 behind an italian camper van or truck only to be caught by a truck I'd passed a few mins earlier. so plenty of trucks must be doing 50 when others are doing 40.

The official report on the A9 states that the average speed of trucks on it is already quite a bit higher than the national average or their speed limit in the 40mph bits. Also, despite only making up 7% of the traffic, they're involved in something like 25% of the accidents.

BTW my own personal approach to the A9 is to try and make sure I only drive on it when it's quiet. That means I might leave at 5am for a weekend hillwalking trip in the summer. In those circumstances the road seems very safe, as there are plenty of places to pass the occasional HGV etc.

It's perfectly possible to make decent progress on it provided you don't get caught in a 50 car tail back.

Yes but from what people are saying, there always is a 50 car tailback..? Or is there miles of empty highway with one or two HGVs on it holding people up?

In those circumstances the road seems very safe, as there are plenty of places to pass the occasional HGV etc.

The thing is its actually a pretty safe road. It gets a lot of attention because of the number of accidents along its length but the rate of accidents is actually fairly low (especially between Perth and Inverness)

I never drive the road for anything than going on holiday so I tend to try and break the journey up by stopping at Dunkeld for lunch, Laggan for a ride or Aviemore for a wander.

I'm all for "making progress" but when I join the back of a 30 vehicle convoy I just chill out and wait for the next bit of DC

pretty much the same, but most of the time it's maybe a 7-8 car "tailback" behind a truck or caravan/campervan. By the time they've all peeled off one by one over several miles, and I'm at the front, there'll prolly be a "dual carriageway in 2 miles" sign.
given that my car is LHD, and I can see jack all round the RH side of a truck, I'll chill.
My estimate was probably about 5-10 minutes difference between chilling out on Perth-Aviemore vs driving near the limit most of the way and taking every passing reasonably opportunity swiftly.

i'd much rather get there a few minutes later, than not at all or in the back of an ambulance. what's the typical wait for an ambulance midway between perth and aviemore?

the most demoralising bit is when you get past loads on a dual section, only find a truck has just entered a single lane zone just up ahead.

I took the caravan up near my parents' place at the weekend. Normally takes me 1h35, with the caravan it took 1h45. Even though it feels incredibly slow to do 50mph, it's not.

The other thing I did see a few times, especially southbound, were 3 or 4 cars bunched up behind an HGV not overtaking but with not enough room between them to let someone else pull in, so committing to an overtake meant having to pass all of them and there's very few stretches where that would be possible. Normal A9 behaviour but there seemed to be more than usual.

There appears to be an assumption here that all of those drivers don't want to overtake, and that they're driving badly because they don't leave you room to leap frog them. How do you know what they've already had to wait for, or how many other drivers may have come up behind them like you? Perhaps they're driving defensively so as not to invite you to overtake dangerously or out of turn? Some or all of them could be just as keen as you to overtake, in fact someone having already done so could be why there's no gaps. You really have no idea why people are driving as they are, but just because you perceive it as hindering your progress doesn't necessarily mean they're bad drivers.

Funnily enough, this kind of scenario reminds me of similarly arrogant and presumptious behaviour in XC racing. Yes, mate, track, we're all stuck behind this slower rider from another cat unable to pass, you're not that amazingly fast, afterall we dropped you earlier.

How do you know what they've already had to wait for, or how many other drivers may have come up behind them like you?

I tried making this point once.. I am still suffering the consequences. Good luck, my friend, you will need it.

Well on the subject of arrogant and presumptious
- how do you know how I came up behind them?
- did, at any point I say it was hindering my progress? No, I pointed out bad driving which, funnily enough is how I'd describe a bunch of cars driving nose to tail at 50 directly behind an artic or a bus.
- do you know how long I sat behind any of them before it became apparent that no overtaking was going to happen?
- so please do tell how any overtaking I might have been doing (if indeed I did do any or maybe just waited until the next dual stretch) would have been dangerous or out of turn?

You do know that not everyone who overtakes someone else drives like a nutter, don't you?, and that some of us know how to overtake safely ?

Even though it feels incredibly slow to do 50mph, it's not

25-30 miles? 😛

Yes but we don't know which you are. A lot of people who drive like nutters THINK they are being safe....

Problem I see with making it all dual carriageway is that you'll get what we get on the A1; massive tailbacks with one lorry taking 15 miles to overtake another with a 0.001mph speed differential!

Then you have to make it a 3 lane motorway (much of the A1) or ban lorries from the overtaking lane at peak times (seems a fair bit of this on the North East A1).

As for average speed cameras we had them on the M62 for a while while the managed motorway was constructed. Everyone moaned about the 50mph limit but traffic did seem to flow better resulting in my run from Huddersfield to Castleford (25 miles) actually being faster at busy times.

Also there seems to be better traffic flow with the motorway management, I have not gone to complete standstill for months now.

Same thing on the M1 now. I get on at 29 and go south in the morning. Before the roadworks it would come to a standstill every day between 29 and 28. Now almost every morning it travels at a consistent 50mph and is quicker on average.

Thats the thing with average speed cameras; they are very effective at changing driver behaviour since they remove the desireto go faster than all the other cars around you. Drivers are more relaxed. In the whole it's a much more pleasurable experience. Once you get used to not being able to travel a 90 mph.

I doubt I'd feel the same when its 9pm, the motorway is empty and I have to drive from Sheffield to Plymouth. It's perfectly possible to travel safely at 85mph in this situation and makes 45 mins difference to time of arrival.

Variable speed limits controlled by average speed cameras are the answer.

They just need ban lorries overtaking, like they do in other countries.

But like I said earlier, a lot of slow drivers also think they're being safe, while driving inconsiderately and sometimes unsafely... Or to put it another way, lots of bad drivers think they're good, whether it's bad driving by being a nutter or bad driving by sitting behind a truck at 40mph or whatever.

I remember my uncle intentionally blocking an overtake and smugly banging on about how he was making the roads safer, when he'd actually almost rammed another car for no reason. Idiocy isn't restricted to hero overtakers.

M1/M62/M25 multilane with variable limits or slower limits designed to make all traffic flow in lanes is a little bit different to a single lane A road thru the hills.

But making all traffic flow at 50 limit is surely better than some doing 40, some doing 50, and loads wanting to do 60 but get "held up" doing 40 for extended periods.

Pretty common to have time limited no overtaking by vehicles >3.5ton on 2 lane sections on the continent. Not exactly expensive to install similar signs on A9. Although IME (even if not that regular), I've never seen trucks passing trucks on the dual zones, and even if they did, i'm sure they'd have the decency to let the cars go first.

A couple of questions I have on this.

1. Does driving in average speed camera areas make one concentrate more on their speedo than concentrating on the road ahead?
2. Would driving at a steady pace have a negative impact on one's alertness?

Regardless....I'll be going up the A82 more often then. It's 'generally' quieter and in bad winter weather it's affected less by snow and ice.

In practise (and if you can choose your time of departure) it only adds 15mins to a journey time from NW Glasgow to Inverness. It's also prettier and a better fun road to drive too! (am I allowed to use the words "a fun road to drive"?!)

Despite it's reputation, IMO I believe it's a safer road...if you're patient and don't get wound up by the sometimes slow tourists!

I've lost count of the number of times I've had 'near death experiences' on both roads, some my fault and some others. However, mile for mile, the A82 is arguably safer IMO. When I do have to overtake then the significantly shorter queues, the slower average speed of traffic allows for far safer overtaking.

In saying all that, even if I were the best driver in the world (which I'm far from), I'd still be brown bread if someone else pulls out in front of me on either road.

1. Does driving in average speed camera areas make one concentrate more on their speedo than concentrating on the road ahead?

If you can't concentrate on both you're not fit to drive.

2. Would driving at a steady pace have a negative impact on one's alertness?

See above.

Meanwhile back in the real world, where the roads are full of people of mixed experience, ability, alertness, tiredness, confidence and machinery

1. Does driving in average speed camera areas make one concentrate more on their speedo than concentrating on the road ahead?

Probably, a little, what percentage of people do you think look at their speedos when they approach a fixed speed camera

2. Yes driving a steady speed probably does have an effect on peoples alertness. I think that's one of the reasons people tailgate. They now have to pay close attention to the distance to the car in front. It keeps some drivers alert (I find it stressful to do the whole tailgate, brake, tailgate, brake thing, but its such common behaviour that there must be a reason for it beyond them all being crap drivers)#

FWIW I prefer the A82 as well.

Staying further back, watching the brakelights in front as the ripple heads back down the line keeps me interested, thanks. And helps save a little fuel.

If you can't concentrate on both you're not fit to drive.

That doesn't answer his question. You keep making these sort of big grand statements that just don't work in the real world, no matter how true they may be.

If you can't concentrate on both you're not fit to drive.

How does the molgrips "fit to drive" test work?
You get overtaken by a motorcycle do you
a - relax, it's just a guy on a motorbike going faster than you?
b - jettison the caravan, pull the flat cap down over your eyes and prepare to accelerate to double figures?
c - burst into tears and immediately post a strongly worded thread on STW?

On a three lane motorway, the middle lane is for
a - you alone?
b - you and any other caravan puller?
c - what other lanes?

A82 here as well. Slower but easier to enjoy, and if is getting stressful, it's nothing a bacon roll and cup of tea at Glencoe Mountain can't fix.

1. Does driving in average speed camera areas make one concentrate more on their speedo than concentrating on the road ahead?

If you can't concentrate on both you're not fit to drive.

in a 20 zone? I stare at teh speedo since getting to 10% over the limit is very easy.

I prefer the A82 to the A9 as well, but it's also a road that suffers from some very dodgy overtakes by impatient drivers stuck behind slow traffic - tourists admiring the scenery etc. I think I've had more near misses from folks doing dangerous overtakes on the A82 that I have on the A9, although I've seen a fair few on both. I know it's a stereotype but the vast majority do seem to involve Audi's these days!

1. Does driving in average speed camera areas make one concentrate more on their speedo than concentrating on the road ahead?

Many many cars have Cruise Control now. I use mine most of the time on the motorway (and often coming into town on multi lane roads with 40 or 50 limit).

If you're unable to cope with this most SatNavs have the option of a speed alert and will beep when you exceed the limit - no need to take your eyes off the road.

The reality is taht you drive at the same speed as the bulk of traffic (which is all trying to drive at 50 now) and check occasionally.

2. Would driving at a steady pace have a negative impact on one's alertness?

Most motorway driving is at a steady pace - the majority of people drive at or near the limit on any road. Yes, it's boring but there's little risk if you leave a sensible space between you and the car in front (2secs/4 secs is way more than most people leave)

I'm far more

Despite it's reputation, IMO I believe it's a safer road...if you're patient and don't get wound up by the sometimes slow tourists!

I too prefer the A82. I've done about 10,000 miles on it in the last couple of years and can honestly count on one hand (ok, maybe two!) the number of idiotic overtakes I've seen. I think with the A82, people who don't know the road tend to be content with sitting behind something moving a bit slower, since it's windy and interesting enough not to make them feel like they must overtake. Then those who know the road will generally sit "patiently" until one of the known good spots.

It often feels more dangerous, but I think in reality it is not. The overtaking opportunities are far more limited and tend to be more obvious IMO. There are very few spots which give you the illusion of being a good spot to overtake and then turn out to be risky etc, plus the overall speed on the A82 is slower so overtakes tend to also be slower.

The A9 is just odd. I sometimes sit, being overtaken while doing 60 and wonder to myself "who are these people?". There's a lot of heroes who seem to fall into the stereotype, but there's also a huge number of middle aged women in 4x4s and old men in bashed up Astras. You just don't seem to see that on the A82 (it seems like it's more limited to van drivers and Audi Gods trying out their Quattro on the first drive in the car that isn't their commute to the sales office at the Staple factory)

Regardless, I never feel more uncomfortable in a car than hitting a straight section on the A9 and seeing a lorry coming towards me in the other direction with a queue of cars behind it. Chances are someone will have a go.

driven it many many times.

There is no way I've ever averaged above 60 on the road north of perth so can't see what difference average speed cameras will make. As the chap pointed out earlier, the HGVs doing 40 causes frustration and huge tailbacks, especially when they tailgate each other. Never driven an HGV but why is it unsafe for them to drive at 60 on a road like the A9, its hardly a country road.

And don't mention the selfish twunts in the HGVs who try to overtake on the duel carrigeway section, and take the entire 2 mile length of it to do so.

How does the molgrips "fit to drive" test work?

blablablabla

What a thoroughly crap post. Not even good enough to properly piss me off.

The Audi thing, btw - I think many of the speedsters are reps, and they tend to get Audis/BMWs/Mercs as company cars.

When it gets turned into a dual carriageway, all that's needed is a few signs like this:

[img] [/img]

I also agree that allowing trucks to go faster until it's dualled might not be a bad idea. 40mph can feel frustratingly slow, especially in my German motorway münscher. It's creating a situation that tempts potential idiots to be actual idiots - although, I guess that potential idiots would probably find 50mph frustratingly slow too. 😕
