dicki has the local knowledge; I know the area reasonably well, but I wouldn't trust myself to design a complete filtering scheme; I'll suggest something below, but that may not be the best option. As ever, there are public buildings in the area and other places that will have particular access requirements that may well not work with this suggestion.
The first thing to say, though, is that I can't answer your question directly, because you need to start not with 'this street should be filtered', but by designating a cell and cell boundary streets, and then filtering every through route in it for general motor traffic. If you start by thinking about individual streets, you usually end up with a partial and inferior scheme.
Some of the cell boundary streets here are easy (A112 Major Road/Chobham Road/Leyton Road/Angel Lane, A118 Great Eastern Road, (the old A11) The Grove/Maryland Point/Leytonstone Road), but the question is whether there should be two cells or one, i.e. whether one should designate Chobham Road (the non-A-road bit) a cell boundary street alongside Crownfield Road. Both options have advantages. If you make cells very large, that can mean worse driving with higher speeds throughout the cell. I think that, given the cell would be quite elongated here, that would probably be a lesser problem, but I also think that filtering gradually, closing minor cell boundary streets when the rest of the cell has proven its worth, is a good thing. As I say, I don't know the area that well.
it's a wide major road ( leading to major road )
Well, it's a residential street that happens to be able to accommodate two rows of car parking with narrow traffic lanes in either direction, as usual at the expense of narrow footways and too little space for the existing mature trees. I certainly wouldn't call it a major road. I mean, you've got Major Road for that. :) I wouldn't have any objection to filtering Chobham Road, and my scheme does both options, but of course I understand your view, and, as above, I don't have a 'feel' for the area.
All that said, I'd probably place the following filters in a cell bounded by Crownfield Road, the A112 Major Road/Chobham Road/Leyton Road/Angel Lane, A118 Great Eastern Road, and (the old A11) The Grove/Maryland Point/Leytonstone Road (roughly north-south):
Some kind of filter at the junction of Edith Road and Colegrave Road. The main problem in designing it here are the access requirements to the Community Centre, which would prohibit a 'Culford filter', my favourite way of filtering (after the four-way filter at the junction of Culford Road, Lawford Road, Northchurch Road, and Northchurch Terrace, in N1). It's quite likely that Edith Road and Colegrave Road would have to remain a loop inside the cell for that reason, annoyingly leaving open a rat-run for when Crownfield Road is stuffed up, but there should at least be a filter on the eastern arm of Colegrave Road. It might also be possible to place a filter in the western arm of Colegrave Road at this junction, which might not attract quite so much rat-running (but would also attract it). It's a bit of a toss-up unless something can be changed in the access requirements of the Community Centre.
A filter in Walnut Gardens, probably not at one of the junctions but in the link.
=======================================================
Two options--(1) if Chobham Road was to be filtered ...
A 'Culford filter' at the junction of Chobham Road and Brydges Road, filtering all four arms of the junction. This would create a public space and would be the most important filter in the area. (It's also the filter that gets closest to answering @Eejit 's question.)
A 'Culford filter' filtering all three arms of the junction of Newton Road and Hughan Road.
(2) if Chobham Road was not filtered ...
A filter in Hughan Road (not at the junctions).
A 'Culford filter' at the junction of Chandos Road and Brydges Road, filtering all three arms of the junction.
A filter in Henniker Road (in the link, not at a junction).
=======================================================
A 'Culford filter' filtering all three arms of the junction of Henniker Road and Community Road. Henniker Road should be returned to two-way operation.
A 'Culford filter' filtering all three arms of the junction of Maryland Road (NB not Maryland Street) and Falmouth Street. Maryland Road and Maryland Street should be returned to two-way operation.
Two filters filtering the northern and eastern arms of the junction of Waddington Road and Waddington Street.
A filter in Francis Street (in the link, not at a junction).
A filter in Windmill Lane just east of Millstone Close, with the carriageway in Windmill Lane widened again and two-way operation re-introduced.
A filter in Grove Crescent Road.
This is all easier if shown in maps (one for each option), which are attached.

Thanks Oliver, very comprehensive reply. I think that option number 1 looks really sensible and is v helpful in understanding how you can achieve the same impacts by having filters located away from the edge of the cell.
I'm also pretty local, and am guilty of previously using Chobham Road as a convenient run through to Stratford. It forms (or did form) part of a larger rat run that span across to the east of Leytonstone Road. I think it's more sensible to route that traffic down Major Road and Crownfield Road. It's a minor detour and the roads are much more suitable to the level of traffic. It also frees up Chobham Road as a more direct cycle route - up to this point it was a pretty horrible road to ride down.
Although you stole the joke I was going to make about Major Road, so now I'm not happy.

Out of interest, where would be the better location for this filter? I can understand why they want to close Chobham Road as it’s a terrible rat run.
