Against whom ?
Is there any reason why some of the sample points don't have before/after comparisons. It seems a bit pointless to have sample points where the other doesn't exist. It's a shame there isn't any sample points at many of the other places that have been effected by the changes, as it would be nice to know if they have actually got worse or not and if so by how much, as so much of this debate has ended up been subjective.
It would be interesting to compare those results with the before and after traffic counts. The after counts have just been made available, and are attached here.I'm away though so don't have the before counts handy. Can anyone find the before counts for Turnpike Lane and the Green Lanes to see how that compares to these NO2 results?
The counts are too big to attach to a post so instead are here: http://harringayonline.pbworks.com/w/browse/#view=ViewFolder&pa...
(poor Willoughby Rd had traffic increase by 22% though, and a big increase in NO2 too from the result of Willoughby by the corner of Sydney)
The lowest reductions were (not counting Allison and Hewitt which were already low) Lausanne, Allison, Willoughby and Pemberton. The first three I can explain: church traffic and through roads, Pemberton I cannot. What on earth is going on that it continues to attract so many vehicles a week despite not being a through route?
Oh and I forgot Duckett which just looks MAD. Anyone?
Perhaps there was not as much rat running traffic as predicted by some on here. The average traffic on the ladder roads post closure is similar to that of the Gardens.
The average count for the gardens is 3822, the average for the Ladder with Wightman closed is 4496 so an 18% difference.. Similar'ish. What that says is that the resident access bollards for the Gardens are about as effective as closing Wightman.
We should get resident access bollards for the Ladder, they would solve most if the issues. Through traffic would be largely eliminated. Allowing the local traffic to use the Ladder and Wightman would get it off Turnpike Lane and Green Lanes so the congestion problems there would go away. And all the problems with locals who must use a car having big delays while Wightman has been closed would be solved.
This sounds like a very sensible idea, I didn't release that resident access bollards were something that are an option. How do these work from a resident point of view, do they have to buy something to use them, or is this provided? Just wondering about the cost aspect (not that I would mind paying for a reduction in pollution), just might be a harder sell
There is an FOI about the cost of the Gardens bollards here.
So £50K to install and about £2400 per year to maintain. We'd need three sets to protect the entire Ladder. Residents pay an annual fee for the access card, and with the size of the Ladder something like £30 a year would easily cover the annual cost plus build up a big maintenance surplus. This traffic study alone cost the council £250k so you'd think they must have budgeted for a similar figure for implementing the results, which should cover the installation cost, or with interest rates so low just take out a loan for the bollards installation and have the resident annual fee pay off the loan.
