FOI responses or research on braking and turning around LTNs and School Streets

[springfleur55]

Apologies if this has been asked before but is anyone aware of published research or Southwark or TFL FOI responses relating to the possible extra particulate pollution resulting from braking, turning and idling at the entrance to LTNs or school streets? I've witnessed so much of it and it would seem to negate so much of the benefit, particularly for school streets where there are usually children walking past reversing cars.

It seems like a perfectly sensible question to me in relation particularly to school streets, given the effect of pollution on children.

I'm considering making such a request but don't want to waste council resources if it's a question that's been asked and answered before.

You really think the  council  has done proper research? If so you have more faith than I….and probably fixed anyhow…

Springfleur55 doesn't know whether anybody - not  the council - has done research.

That's why they are  asking the question. It's an important issue.

They are also asking about council or TFL  FOI responses.

What do you think could be "fixed"?

Well let’s face it,

ask what they want but don’t listen…just do their own thing…

To be fair, this is both a very valid issue to raise, and one which would be very difficult to research, not least because there are no valid measurements for emissions at the key 'manoeuvre' spots before the introduction of the changes for comparison. Face validity would suggest that there must be some additional emissions, but exactly what, and what the implications of these are, will be very difficult to measure in a way which can't be reasonably challenged.

Oh please, not another anti LTN thread.....

So the hidden agenda (is it hidden) is that the OP wants school lanes reopened.  That is a very sad view that motorists come before school childrens' safety.

As for the post, fire away with an FOI.  Don't just talk about it.  Be my guest.

As someone who has worked in transport I can tell you some more.  I've posted many times on this forum, and in the past before COVID we had some interesting conversations on the Lounge.

Firstly - you could ask the question about congestion as a whole.  London has had road congestion even in the days of the horse and cart (where at one point there was a worry that we'd have roads full of horse manure).

Local authorities may have in house expertise or use traffic consultants, I expect the latter.  Standard transport assessment models are likely to be used developed by academics and consultancies.

Reduction of soot emissions from cars (fine particulate matter) has been significant in the last 30 years as emission standards have become more effective.  Particulates come from a variety of sources and since the reduction from transport other sources, in particularly combustion - and in this respect wood burners, are now the main areas of concern.

Modern petrol and diesel cars come with stop start so should not sit their idling unecessary whether you are on a main road or a back road.  UNLESS YOU TURN THIS OFF.

I haven't a clue why turning would be an issue,  When you drive you often turn round bends, at junctions etc. Odd question.

Brakes produce larger particulates, the size that will not pass through the lungs into the cardiovascular system.  The average driver cannot drive smoothly, have a look at any speed bump and nine out of ten will speed up, brake, speed up, brake. If drivers thought about the waste of fuel, wear and tear on the car and impact on their passengers the world would be a better place.

Your time would be better spend on how you could encourage less and smarter driving.

The main issue from transport emissions is from oxides of nitrogen.  Post VW scandal newer diesels are far cleaner.
