That's a 'system' problem, not a 'drivers' problem. It needs a system solution.

And don't go saying: "it'll take too long", because the true objective is to make things a little better each year by nudging the system in the right direction. Present policy - where drivers are 'to be controlled' is actually making things worse.

Have you got any specific 'problems' in mind?


Where drivers are deliberately breaking well set limits because they cannot see the need to drive at or below the limit.


There are very very few such places. If any. Can you offer any evidence at all that such a place exists?

Seafront boy racer meets, maybe - but that's the sort of thing you're looking for.

I play golf - can be risky in a thunder storm.... :roll:

Mad Doc plays rugby as well - and once broke iis leg in a tackle - OK - as I understand he made a mad dive in a scrum ... :roll:

Wildy speed skates and skis, still plays ice hockey when she can - but these are risky hobbies and after watching the Winter Games - you really have mad to use a tea tray that way .... :lol:

But these all have elements of "risky behaviour" - and all are legal....

Absolutely. Drivers have to take responsibility for themselves. Amongst other things this means that if the do the crime, they should do the time.

Just about every urban road with a well set 30mph, for starters.

And if such a place doesn't exist, why do we need the limits?

Now that's pure make believe. Drivers are what drivers are, and to a lesser extent what the system makes them. It's up to the system to give guidance and responsibility.

There's NOTHING that you can do to FORCE drivers to take responsibility.

I think we have another difference of perception here. I would say that on a large majority of the urban road mileage with properly set 30 limits, most traffic travels within the limit.

If the problem is a small minority of drivers, then the way to address it is through targeted enforcement action, preferably stopping and speaking to the offenders at the time of the offence.

I think what you are describing is confined to a relatively small proportion of the total mileage and pretty much entirely on main roads.

Of course, many main roads that under Roads 1/93 should have 40 limits have now had them reduced to 30, but I wouldn't class those limits as "well set" :wink:

I think the latest DfT figure is 57% of cars speeding in free flowing conditions at sample sites. (And it seems they have to choose different sample sites to get it down from 60%+.)

And there are time of day issues. I think it was over 80% speeding between 7am and 8am in the most recent VSGB.

Yes, but those will be on main roads and not representative of all 30 mph limits. Very little traffic speeds on 30 mph residential streets, which make up the majority of the urban road mileage.

This is silly. Clearly you're telling us that speed limits cannot be called speed limits - because equally clearly they will never be perfect neither in enforcement nor in being observed. We just have to haggle about the appropriate degrees and methods of softness.


No need to confuse us with more BS. If you break the limit, you have broken the law.

The laws on drink, or tyre depth are not made soft just because people break them! Before you indulge yourself further by leading us up blind alleys, the law defines the limits, and it is up to us to obey them. All I’m asking you do is your duty – please be bothered enough to do that.


Basing mate - road safety matters to us here - and we target the blatter and apply discretion when and wehere appropriate. It does not do to nit pick or be overly draconian over slight blips. Most take on board what we say to them - and it does depend on how you say it just as much as the qualityu and substance of what advice you give.

Right advice - delivered right way tends to stick - and you make sure that the point is made at the astaret and the end of your spiel as this is what peope tend to remember best and longest.

No-one said anything contrary to that. But as you say, drivers are what drivers are - and if they're irresponsible, clearly you can't hope they'll be responsible - you've got to punish them for behaving irresponsibly and disqualify them from driving if they don't change their ways.

But that is missing the point.

As I'm sure you're aware, "an accident is a rare, random, multi-factor event always preceded by a situation in which one or more road users have failed to cope with their environment". If the other factors to conspire to create the accident aren't there, then the driver gets away with driving too fast for their environment.

Its a question of risk. The fact that most of the time people get away with it is neither here nor there - even playing Russian Roulette has a 83% "escape rate".

I thought you didn't need this warning, and that having a limit in this instance would be inferred as stating the safe speed - so wouldn't the limit be counter-productive?

Ok NDP, let me ask you a few questions for a change, then I'll answer your other points. We have a huge amount of cameras, we have an unprecedented number of speeding convictions, yet road users are still dying even at camera sites:

1) What would you do to solve the problem as an engineer, taking into account cost implications, traffic flow, political consequences and above all, the current failure to reduce serious injuries and fatalities?


Generally or at problem sites?

And I'm not sure what the point of this is. Given those constraints, it wouldn't be much different to what happens now, which is essentially the result of said constraints.

EDIT: Given its not me who claiming what is being done is rubbish in the circumstances, why am I being expected to come up with an alternative? Surely the onus for that is on those who want to seek change?

Cameras only measure speed and the ones who get pinged? Usually the ones who think they only cop bad drivers.... :roll:

A speed limit is not always the safest speed - sometimes you have to use judgement and drive below the limit and just sometimes - not overly often - but sometimes you need to blip over to complete an overtake - and you could be overtaking an nippy cyclist and just as you are at pont of no return - you note a hazard developing ahead in the shape of a bus at a bus stop or some person doing something which means the cyclist needs his "primary" - and the only way out is to speed up the pass to get to lane and back to compliant speed without compromising the cyclist - and allowing him time and space.

Or on a motorway - some speed to make the gap and retrun to limit safely and smoothly. There are then some areas whereby bliipping over is more in line with safety than rigidity.

Oh - we use cams - only we have them were they should be - in trafpol cars - operated by trapol and other qualified officers - and we uise common sense and professional judgement - which is how it should be.

Occasionally -= we may get it wrong - we do have people having accidents. We had one we fiend for not wearing a seatbelt. Officer gave him the standard lecture and two weeks later he was involved in a crash. All signs inidcate it was not his fault :wink: - but he is alive :) and not seriously injured because we spelled out the dangers when we fined him. He is quoted in a local paper as being grateful to us.

We seem to find a lesson and advice on the spot helps a lot more. Lancs have problems because they targetted the wrong "customers" to the Speed Course. However, of those who have attended to date - they kept data bank and found NONE have been involved in any incident or received any further fines since they began the COAST led course. Their accident rate is still higher than it should be though - and we can only conclude that the cams have shifted the traffic density around. Where there is density - greater risk of sill error which because of volume leads to tragedy. They, like Durham, have a spot which seems to entice the born again biker from hell like a candle to a moth.

You seem to forget the "selling point" of cams is "accidents.

We have a blip here in 2002. Our rate doubled. It was still lower thna UK average as 2002 seemed a bad yeqr all round - but we got hammered and answers were demanded.

Why?

because we did not subscribe to the cam on every corner philosophy and considered our area was best served by ubiquitous patrols and one van

Nope. Lancs was inviting people to its speed course at 34 mph at one point.

There is a difference between a blip - easilly corrected and someone who deliberately blats. We tend to go for idiots.

A 30 mph sign to me means "built up" and prone to lots of hazards - like side streets, crossings and so on. It gives a stranger to an area a clue.

I also look at road marklings - these tell me a story - like reading a book.

He's actually made some proposals here:

http://movement-uk.blogspot.com/

Quote:
So how do we go about doing this? Well, my opinion is that the authorities need to take a grip, decide what they want to do with speed limits and enforcement, and then do it consistantly. How about this for a plan-

a) Set the national speed limits to be 30 in urban areas, 60 outside of urban areas on both single and dual carriageways, and 80 on motorways, with a provision to raise the speed limit locally to 70mph on major, high quality routes (this provision could be restricted to primary or trunk roads; I'd also suggest that long distance largely-grade separated trunk roads, such as the southern section of A34, or the A14, should be upgraded to motorway)

b)Local speed limits should be set in accordance to something broadly similar to DfT roads circular 1/93[1], but with more emphasis on ensuring any frontage is sufficiently sparse or well set back for limits higher than 30 mph, and additionally with provision for 20 limits in town around schools (ideally on a variable basis arrived to in partnership with the schools), or where footways, sightlines etc are substandard.

c) 20mph zones should be standard for residential side streets, and for busy shopping streets.

d) Highways authorities should be expected to adhere to b and c, and this should be enforced in order to ensure limits remain fair, consistant, and thus credible.

e) Speed limits should be enforced as local authorities deem appropriate. Speed cameras should be easier to install, and should not be dependant on statistics regarding accident rates or whatever. Additionally there should be no requirement for the cameras to be made artifically visible (eg by means of diamond grade on the camera, or by speed camera repeater signs) - however, deliberately hiding speed cameras should be discouraged (this practise does nothing for public confidence). There should be no guidelines on prosecution tolerances, and tolerances should be set as low as the accuracy of the speed measuring device, or 3mph, whichever is higher (though practical considerations may dictate higher tolerances - this should ideally be considered on a site by site basis).

f) Speed camera warning signs should be optional, and should only be used when and where enforcement is taking place.

Of course, this isn't all of the package, there would need to be real educational efforts to get people to understand what affects the appropriate speed they can drive at so they can recognise hazards as they develop and react accordingly (hardly anyone seems to be able to realise that they can't see over a blind crest and should slow down for instance - you won't solve this aspect of the problem with speed limits).

Controversial? Maybe. But we're not getting anywhere by fudging policy to attempt to appease everyone in both sets of trenches, all of the time.

Of course, if I were the Minister for Transport I'd be telling my Road Safety Minister to go get on with it.

Aside from that, I am not privvy to all the information I would be were I secretary for state. So the first thing would be to see whats in progress and look at the new information available.

Everything else would follow from that - to decide anything beforehand would be entirely prejudicial.

And aside from that, the given the same constraints would apply, so wouldn't I be constrained to the same policies?

Thats missing the point - whether you're interested or not is immaterial. The onus is not on those advocating the status quo to justify their position, but for those seeking change to provide an alternative and show it to be an improvement.

Firstly, I wouldn't get too excited about anything being added to that blog. It was a blog which I quite frankly haven't found interest in maintaining.

Secondly, those proposals would breach constraints. Anything other than high-visibility cameras have proven to be politically infeasible (though I gather they are on the cards again).

EDIT: Also, that only deals with the speed issue. Of course there are other issues to be dealt with, but the blog entry was written in response to an article on speed, hence its focus.

This is really the critical mistake in road safety policy. It's true that when you drive faster than a certain speed in a certain circumstance risk goes through the roof.

But driving at 30mph would put the risk through the roof in lots and lots and lots of urban circumstances. We don't have anything like enough crashes or anything like the crash severity to support the idea that this is actually happening. So why isn't it? It can't be the speed limit doing it - it can only be appropriate speed behaviour.

It isn't true in any practical or useful sense that risk increases as you exceed 30mph. Risk really only increases with speed if you can't stop (comfortably) within the distance that you know will remain clear. Drivers are amazingly effective at this, and you can bet that where the 85th percentile speed is above the speed limit the speed limit is unecessarilly low.

He's actually made some proposals here:

Firstly, I wouldn't get too excited about anything being added to that blog. It was a blog which I quite frankly haven't found interest in maintaining.

Yes, I suspected that was the case, but as you had set out some thoughts on the issue I thought they were worth bringing up. I set up a blog myself once which lasted about two weeks...

Secondly, those proposals would breach constraints. Anything other than high-visibility cameras have proven to be politically infeasible (though I gather they are on the cards again).

Discussed in this thread:

http://www.safespeed.org.uk/forum/viewtopic.php?t=6035

AIUI the current guidelines allow a limited use of covert mobile enforcement, and also covert fixed cameras if specially approved, although I'm not aware of any SCP that has taken up the latter option.

And, as discussed before, Talivans drive a coach and horses through the visibility rules already :x

Just about every urban road with a well set 30mph, for starters.


The accident records prove you wrong. Those millions of speeding drivers simply aren't crashing.



But that is missing the point.

As I'm sure you're aware, "an accident is a rare, random, multi-factor event always preceded by a situation in which one or more road users have failed to cope with their environment". If the other factors to conspire to create the accident aren't there, then the driver gets away with driving too fast for their environment.

Its a question of risk. The fact that most of the time people get away with it is neither here nor there - even playing Russian Roulette has a 83% "escape rate".


This is really the critical mistake in road safety policy. It's true that when you drive faster than a certain speed in a certain circumstance risk goes through the roof.

But driving at 30mph would put the risk through the roof in lots and lots and lots of urban circumstances. We don't have anything like enough crashes


Don't we?

And don't forget, an awful lot of crashes are thought to go unreported.

anything like the crash severity to support the idea that this is actually happening.


We do have a pedestrian & cyclist fatality rate that is rather poor compared with many continental countries.

So why isn't it?


I dispute the assertion that we don't have the number of accidents to support the idea.

It can't be the speed limit doing it - it can only be appropriate speed behaviour.


Plays its part, but the limit is needed where the behaviour isn't there.

Quote:
It isn't true in any practical or useful sense that risk increases as you exceed 30mph. Risk really only increases with speed if you can't stop (comfortably) within the distance that you know will remain clear.


In an urban environment, thats quite often at speeds over 30.


Quote:
Drivers are amazingly effective at this, and you can bet that where the 85th percentile speed is above the speed limit the speed limit is unecessarilly low.


So do you think the 30 limit should be raised, on major roads at least?

And theres the damage limitation issue, of course.
