Do you consider 30mph to be the definition of a speeding car? As I was saying....ideological claptrap. 

The blanket rollout of 20mph by councils like Southwark was driven by an anti-car ideology and was not at all pragmatic. I think some in the active travel lobby would refer to it as a "nudge technique"...

 

Your blinkered thinking is shocking.  I cycle maybe 15 hours many weeks in London.  20 mph makes it so much more welcoming.  And much safer for pedestrians too.  I really can't get my head around your position on everything brought in to make our streets safer and encourage people to drive less and use active travel.  Is this really because of the LTN?

Because often those measures are not brought in pragmatically. The A205 being 20mph is one of those, the Westway elevated section being 30mph is another. I very often cycle to West London and I would never want to cycle along the A4 no matter what speed it was - that's me being pragmatic. I often see people trying to and I often think that is being driven by ideology or stupidity - or a dangerous combination of both! I have been doing that journey far longer than the 20mph blanket measures were brought in and the route I chose to go those measures have made zero difference because the route I use is wonderfully quiet and always has been. 

Do you really think the A205 should be 20mph? It's one of London's most important arterial routes and is the very definition of a 30mph road in the Highway Code. 

Surely you can put your ideology aside and use your traffic management expertise to acknowledge that?

It would help if you quoted my  post you are replying to. How convenient that it was at the end of a page.

30mph is significantly faster than 20mph - 50% faster -  otherwise there wouldn't be much point in having reduced  the speed limit, for the reasons given.

I notice you completely ignore the rest of my post. 

I will copy and paste it here to jog your memory.

"Maybe people might be more inclined to cycle and walk if they are less at risk from speeding cars whilst doing so, and their journey is generally more pleasant?

How do you define a) ideological and b) claptrap in this context?

And what is your opinion on the other two reasons, ie reducing collisions and helping to improve air quality?"

Well @Sue I answered the first part addressing the "more people will walk and cycle if the speed limit is 20 mph" in my previous messages.

TFL has actually addressed the claim around pollution by saying there is no difference in No2 pollution at 20mph but that if cars are driven in a "smoother" way at 20mph there may be a reduction in particulate matter. I think we all see cars being driven less smoothly as they accelerate and brake between speed cameras.

Collisions, yes of course reducing speeds reduces the risk of accidents but most accidents happen at junctions and the A205, in the main, has junctions controlled by traffic lights.

This is why that statement by Southwark is so flawed, much of what they claim does not pass the scrutiny test, it is a collection of ideological soundbites they know they can throw out and their supporters will throw around as fact. On this thread alone there have been two very clear examples of people making claims that are just nonsense (claims that police set the speed limit in the area and claims that 30mph on the Westway was because of ageing infrastructure). 

And this is the point, a pragmatic approach would say roads like the A205 should remain 30 mph, but the pragmatic approach is not the one taken.

I ask you again, do you consider 30mph on a A-road like the A205 to be too fast or as you refer "speeding".

"nonsense claims that 30mph on the Westway was because of ageing infrastructure"


"Speed limit restriction

The speed limit was reduced in July 2020 from 40mph to 30mph along the entire stretch of the Westway between the A40 Northern roundabout to the west and Marylebone flyover to the east.

Slowing the speed helps protect and extend the life of the ageing expansion joints in the road until they can be replaced. This makes it less likely we'll have to close parts of the Westway for unplanned works."

@Rockets in response to your response to Sue

1.  Pollution.  Cars accelerating and braking between cameras.  This is poor driving.  I don't drive like that as I am an excellent driver who has had additional training.  Anticipate the road ahead, light touch on the accelerate and be prepared do stop when you see stationary traffic ahead, approach junctions and the like.  You can't excuse bad driving and blame it on 20mph zones.

2.  "Most accidents occur at junctions".  Rather a sweeping statement?  Firstly it is collisions not accidents.  Secondly this statement does not break down the types of collision, speed and harm.  Motorised vehicle on motorised vehicle; vehicle/fixed object; vehicle/pedestrian; vehicle/two wheeler, and vice-versa (I once walked into a car as a teenager that stopped suddenly in slow moving traffic in my local high street (ouch).

3.  Haven't got a clue what the flawed argument is by Southwark.  In England speed limits are set according to the road, local authorities have powers to set lower speed limits, as many do (not just in London).  One third of the population of the UK live in local authority areas with 20mph zones https://www.20splenty.org/20mph_places  

The Mayors' commitment to zero KSIs by 2041 starts with 20mph in all of the congestion charging zone, which I expect has been achieved.  Law of physics is that with every 2 mph over 20mph there is 10% greater impact if a vehicle hits a pedestrian and an even greater impact on stopping distance

4.  South Circular.  You failed to address my earlier point that virtually all of the South Circular all the way from Waterloo plumbing in Catford to Kew Bridge is a series of minor roads with shops, schools, houses, many junctions, pedestrian crossings.  It's not a dual carriage arterial like the A40, A4, A2, A20, A3, A21 after Bromley etc etc.  20mph is an appropriate speed limit.

Thanks heavens less and less of the next generation will own cars and regularly drive in the inner boroughs, and will make more and more use of the transport options available.

Worth looking at the update on Mayor's plans and Met Police work on supporting this: https://www.london.gov.uk/motions/vision-zero-targets

 

 

Rockets, who’s argued for 20mph speed limits when people are travelling by bicycle (which would involve a whole new system of registration and licensing and changes to primary legislation), is against those same speed limits for cars? 🤔 

Yeh, nothing ideological there.

20mph has saved lives. It makes almost no discernible difference to overall journey distances. So what exactly is the argument against?

Absolute nonsense. The 30mph was applied in 2020 as a temporary order whilst joints were replaced and then once the work was completed TFL made it permanent under their "Lowering Speeds Programme" in 2021 to "reduce road dnager".

@snowy maybe go back and re-read what I posted…..you have conveniently ignored what happened in 2021….why might that be?

I am sure you believe you are an excellent driver @malumbu but only if everyone drives that will does a reduction to 20mph has a positive impact on pollution levels (according to TFL and Imperial College). A lot of people do not so what does that do to claims made by Southwark that 20mph reduces pollution? Probably renders if meaningless…..

One backed up by data that shows that is indeed the case…it doesn’t take a genius to work out why.

Only few posts back you were claiming I was questioning your “expertise” because you said the police set the speed limit and I challenged you that they did not. I am glad you have acknowledged that your expertise didn’t quite extend to that fact and that it is the local traffic authority (TFL and Southwark where we live) sets the speed.

And you fail to address the point that by the definition within the Highway Code it is a 20mph road and it is one of London’s key arterial routes that was developed as such. There are many ruins where it is more than one lane in each direction. According to the Highway Code 30mph is an appropriate speed limit.

Let’s back up a bit @Earl Aelfheah as you are doing your usual trick of putting words into people’s mouths again. Please try to get your facts right, I am, saying that a more pragmatic approach is needed rather than a blanket 20mph…..which no more than a few posts back you also seemed to agree with….

Hang on, no more than few posts ago @Sue was claiming 30mph is 50% faster than 20mph….yet you claim it has no discernible difference to journey times. Which one is it?

@rockets 20mph has saved lives. It makes almost no discernible difference to overall journey times. So what exactly is the argument against?

And why did you have no issue with it when you were arguing for the same rules to apply to people using a pedal bicycle?

It wouldn’t be ‘ideological’ would it?

How come then that the Welsh government’s own impact assessment/research suggested that the blanket 20mph across Wales would cost the Welsh economy £4.5bn over 30 years…..? Has anyone done a similar piece of research for London?

I think you are confused as I have been calling for bicycles to adhere to the rules of the road and the fact that it is ludicrous that the speed limits do not apply to cyclists and when a cyclist killed a pedestrian whilst he was doing around 28mph he faced no legal recourse by claiming the speed limit did not apply to him.

1.  Comparing the whole of Wales with it's much lower population density with central London and the inner boroughs is ludicrous

2.  There are already powers to prosecute cyclists who endanger life.  It's up to the CPS and courts to decide whether to take further action and they, in the small number of cases, have decided not to.  Wanton and furious driving under the Offences Against the Person Act 1861, with a maximum penalty of two years imprisonment. Gross negligence manslaughter in extreme cases.

3.  Have you ever been on the South Circ from Catford to Kew Bridge.  Awful much of the time.  As it has been for tens of years.

4.  The police enforce, government and local authorities set speed limits.  My apologies, I sometimes don't read your posts fully as they often say similar things. I was assuming that you were going on about enforcement being a cash cow for local authorities.  Which comes up fairly frequently on many threads.  I've added square brackets to my earlier posts to clarify.

As Malumbu says, the comparison between densely populated London and Wales is obviously ridiculous. But worth noting that even in the Welsh government’s initial impact assessment, those figures you quote were based on the average journey being one minute longer. The method for monetising these small delays is under some debate. The large savings from significant reduction in serious injuries and deaths, less so.

In central and inner London, moving slightly more quickly towards a line of vehicles / set of lights, makes little to no difference to overall journey times.

It is untrue that a cyclist who has caused a death through collision cannot face legal recourse because of existing legislative framework.

And you were explicitly arguing for 20mph limits on those travelling by bicycle. Now you’re arguing against 20mph limits for those travelling by car, van or HGV.

…whilst accusing people of being ‘ideologically driven’.

But over which roads? - no one, I believe, is disagreeing that a 20mph limit on residential roads (in London by far the largest mileage of roads) makes safety sense, and will and probably has, substantially reduced the impact effect of accidents, and these figures go into your statistics - you need to demonstrate that the speed limit reduction on A roads has had a significant impact as well.

With the possible exception of the south circular, I can’t personally think of a road in Southwark where a 30mph limit would make any difference to your overall journey time.

The thread btw, was about Peckham Rye, by piermont green, which has very visible speed cameras and a very clear and appropriate 20 speed limit.

Driving at 30 round here (which just means accelerating and breaking harder), is absolutely pointless, increases your stopping distance considerably, increases pollution, and makes it more likely you’ll hurt someone else.

For those who are concerned about speed in Barry Road - the police are doing a Road Watch on 31st October at 2.30 pm at the Etherow Street junction with Barry Road.  Last time we did a speed check on Barry was some years ago so will be interesting to see the results. Come along and participate  - last time we all took turns with the speed gun.

Imagine the economic impact in a densely populated area....

Yes and every mile at 20mph rather than 30mph takes one minute longer.......makes you think....

Well that's the defense the cyclist who killed the lady in Regent's Park offered during the hearing....
