HCG's air pollution monitoring with Wightman open and closed - Harringay online2024-03-29T10:25:39Zhttps://harringayonline.com/forum/topics/hcg-s-air-pollution-monitoring-with-wightman-open-and-closed?commentId=844301%3AComment%3A912127&feed=yes&xn_auth=noHi Maddy - the "after" data f…tag:harringayonline.com,2016-09-04:844301:Comment:9147742016-09-04T10:30:15.195ZJoeWhttps://harringayonline.com/profile/joew
<p>Hi Maddy - the "after" data for Green Lanes at the Arena - the next junction along from Umfreville - actually shows a <a href="http://www.harringayonline.com/forum/topics/green-lanes-guess-the-current-traffic-volume-competition?commentId=844301%3AComment%3A914668" target="_blank">slight reduction</a> in traffic volume of -2%.</p>

<p>Hi Maddy - the "after" data for Green Lanes at the Arena - the next junction along from Umfreville - actually shows a <a href="http://www.harringayonline.com/forum/topics/green-lanes-guess-the-current-traffic-volume-competition?commentId=844301%3AComment%3A914668" target="_blank">slight reduction</a> in traffic volume of -2%.</p>
<p>This suggests that the Green Lanes congestion isn't fundamentally about <strong>volume</strong> (volume only increased by 12% at Duckett) but about <strong>obstructions to flow</strong>. For example - and as stated on many other threads -</p>
<ul>
<li>poor design of Arena junction</li>
<li>poor positioning of bustops at both Salisbury and Arena</li>
<li>too many traffic lights in close succession at both Salisbury and Arena</li>
<li>phasing of traffic lights - these were not adjusted during the Wightman bridgeworks</li>
<li>insufficient restrictions on parking/loading</li>
<li>ability to make right turns out of rungs/gardens, or U-turn from parked position (in both cases holds up traffic in both directions until the manoeuvre is complete).</li>
</ul>
<p>Before the Wightman bridgeworks these multiple issues were masked (though still with regular flare-ups) because as soon as Green Lanes traffic starts to queue, vehicles can ratrun up the next rung.</p>
<p>Unfortunately I'm not seeing any evidence that the Council understands this (e.g. Peray Ahmet's statement that "<a href="http://www.haringey.gov.uk/news/wightman-road-completion-date-announced-network-rail" target="_blank">Wightman Road is vital to ensuring the smooth flow of traffic through our borough</a>").</p>
<p>What is really <em>vital</em> (literally, in terms of reducing early deaths from pollution, road accidents, obesity) is a permanent low-traffic solution for Wightman, and some radical changes on Green Lanes itself.</p> Another interesting thing fro…tag:harringayonline.com,2016-09-02:844301:Comment:9141762016-09-02T07:28:30.312ZFriends of Fairland Parkhttps://harringayonline.com/profile/FriendsofFairlandPark

<p>There's no 'after' data for Green Lanes at Umfreville, which shows one of the highest levels 'before'. Hard to imagine, with the near-constant traffic jam there in the past months, that pollution would be down - it certainly doesn't feel like the air is cleaner.</p>

<p>To be honest, the small difference that other people in adding some additional people to the area that have access wouldn't make a massive difference. If it get's more local support it would certainly be worth it.</p>

<p>I agree it seems relatively cheap and seems more practical than some other proposals and might get more traction because it allows people to still use their cars. <br/><br/>What I'd like to see is rather than just a single group like Living Wightman pushing their idea is to get together a list of possible solutions and socialise them with _everyone_ to find something that would work and get buy in from all the big and small groups and individuals in the study area. And we should do it not just wait for the council to propose/do something as we know better what would be good. I imagine it was the Gardens residents that proposed their bollards to the council not the other way around. <br/><br/>For example, even with just suggesting this here JulieB has commented on the other thread that if the Ladder bollards work like the Gardens ones it wouldn't help her as she wouldn't get access - so lets just change it so she does - Joe worked out that there were over 200K using Wightman before the closure and from the after counts we see its down to just 50K using the rung roads now so we know there is plenty of room to widen access for a few more locals if it would help get their support and still keeping the Ladder relatively free of through traffic.</p> I think that red spike is chu…tag:harringayonline.com,2016-08-31:844301:Comment:9135132016-08-31T17:17:33.079ZJoeWhttps://harringayonline.com/profile/joew
<p>I think that red spike is chucking out time at the church. You'd expect to see a similar spike an hour or two earlier on Lausanne as people arrive, except I understand the Greek Orthodox folk are quite relaxed about start times so it's probably much flatter.</p>
