Why should the word "other" appear in both those sentences? Okay, Wightman is part of the ladder-type structure that gives the area its name but no-one thinks of Green Lanes as part of Harringay Ladder. Ergo if you live on Wightman Road you don't live on the ladder.
"why LW keep dragging the ladder roads into the mix"
As was discussed here the vast majority of traffic follows a rat-run which includes a part of Wightman plus a rung. Hence the excessive traffic on many rungs, and the horrendous traffic on Wightman itself, are inextricably linked.
Width restrictions would cut down 1000 HGVs per day but not impact 1000+ cars per hour.
As for funding - as I've said before simply changing the Ladder road layout would be relatively inexpensive, certainly in terms of ROI for the benefits it brings. I don't have any experience of how funding works but I think the council puts up some, applies to TfL for some (Enfield, Walthamstow and Kingston all got £20-30m for their "mini-Hollands I think), does a deal with housing developers for other improvements.
1000 HGVs a day ?
Wightman Road is no-go for vehicles greater than 7.5 tonnes ( except for access ).
Why does the Council let them get away with it ?
John D - "1000 HGVs a day" - that's correct, plus over 1000 cars per hour all day (actually over 1200 cars per hour in the afternoon) here is the data for 6th Jan 2016 (with St Anns as a comparison):
"What are the council doing about it" - they are at least giving us an opportunity to say what kind of streets we would prefer to live in. If we don't tell them Filtering Wightman is our preferred option I'm afraid they will assume we're happy with heavy traffic.
I refuse to believe that 1000 HGV's use Wightman per day. I certainly wouldn't choose to take a 40' trailer down there.
I do believe however, that the observers couldn't tell the difference between vehicles for the purpose of classification.
Eyespy - it's incredible isn't it? That a narrow street which for the majority of it's length is purely residential in character is expected to carry over 1000 HGVs per day (plus 1000-1200 cars per day)?
To be fair the Class 4 vehicle counts are less at the weekends - less than 400 on as Sunday:
The counts are not subject to human classification error by the way - they are based on electronic "road tubes" which counts the axles and measure the air pressure when the vehicle passes.
Ah the road tubes, not know for their accuracy in classifying vehicles due to the method of relying on axle spacing.

ANPR would have been a better option as it would have given access to the full vehicle information to properly classify. Hammersmith and Fulham use this method for their traffic studies.
Eyespy - the road tube vendors claim 99% accuracy, and studies show error rate approaches zero over a whole day (due to errors in each direction cancelling each other out).
But even if the accuracy was ±10%, it would still be over 1000 HGVs per day.
you might do andy, but i suspect that there are those amongst us who would argue against one road closure whilst fiercely protecting others.
