Big agreement from me.
Living in the largest city in Western Europe that largely is the same as it was in the 1800's will have it's downsides. If it was flattened during WW2 and rebuilt to suit modern life then it would be vastly different.
Please check the figures Andy - Wightman didn't reduce to zero, it was filtered rather than closed, so residents and visitors used it to access their home, and residents of the relevant rungs would use a portion of it to get back to Green Lanes. The traffic flow on Wightman was higher than most Gardens roads.
Figures are here: https://batchgeo.com/map/dffd78475ca0d105236f9860a0555b49
"Every road should take its fair share" - yes but according to its capacity - carriageway width, residents parking requirements, pavement width, house frontage. As I've said before I'd be very happy to see other roads filtered or protected. But Wightman is by far the worst affected on all these criteria.
Andy "Wightmans a mile long, of course it had more traffic flow" It was a mile long for cyclists but closed to motorised through-traffic so it can't have been ladder neighbours going shopping. Here's the data for one weekday when Wightman was filtered (click image to enlarge):
There were concrete blocks on Wightman just north of Effingham and just south of Beresford, preventing motorised through-traffic but permeable to cyclists (probably some pizza delivery mopeds in there too). Hence the class 2 vehicle count for Wightman at this point is the same as for Effingham and Beresford - ratrunning has been eliminated and the streets are just used for access to residents homes (and no doubt a bit of parking for the shops and restaurants on GL at this point).
For comparison, here is Chesterfield Gardens on the same day - not surprisingly very similar figures for a road which is similarly protected from through traffic:
An oxbow lake by the way is completely cut off from the original river - Wightman and the rung roads will form loops but still connected to GL to allow residents' access.
Try this Andy.
(And, oxbow lakes are formed when the river breaks through the isthmus rather than the meander silting up. I can't see the analogy being apt in either case, although "meandering the Ladder" has a certain appeal).
"general air of unfriendliness"
Actually there was a noticeable increase in people using the space at the front of their houses, conversing with neighbours. Traffic severs communities, eliminating through traffic enhances it.
Pat - the congestion between the Salisbury and Manor House caused increased journey times of a couple of minutes:
Weekdays from Wood Green to Manor House was similar as I've already posted here.
I think those few minutes would be significantly mitigated by some of the measures already proposed in the plans - improving junctions, relocating bustops etc. Reviewing parking and loading (or even properly enforcing the current restrictions) would also help.
It's also interesting to look at east-west journeys - buses towards Muswell Hill were again a few minutes slower, but coming back actually a few minutes faster:
The most affected journey seems to be Crouch End to Turnpike Lane - but in the opposite direction not much difference:
As I've said in other posts, that eastbound traffic from Crouch End was badly affected by the lack of adjustments to traffic light phases at the Turnpike Lane junctions with Green Lanes, Wightman Road and Church Lane - fixing those traffic light transitions would be the main mitigation, but again reviewing parking and loading and if possible the busstop location on Turnpike Lane would also help significantly.
The other thing that would help significantly is if opponents of Wightman filtering would stop trotting out the same canards (or hyperbole as you said on another post) about "chaos", "traffic hell", "like a car park" etc. Yes there was significant disruption for the first few weeks of the bridgeworks and continued inconvenience and unreliable journey times but they improved over the months and there is certainly plenty of scope for further mitigation. Filtering Wightman Road plus mitigations would not only rectify a significant injustice against Wightman Road residents but actually benefit the whole local community on both sides of Green Lanes and much further afield.
