Westminster council are doing two important things at the moment. There is a consultation on "Oxford Street District" here: https://osd.london
The other thing WCC are doing is going to close Riding House Street with the Camden boundary at the junction of Cleveland Street by installing bollards across the road. The street has already been closed for over a year and it has had no negative impact. Camden have already done this at Fitzroy Square and Warren Street and it has been very positive. We need to do more of the same.
The issue of through traffic -- including Torrington Place -- needs to be dealt with as a matter of urgency. All areas of Fitzrovia are above the legal limit for NO2, except for Crabtree Fields open space. (Sample readings: 55 µg/m3 - legal limit is 40 µg/m3. NO2 pollution on Oxford Street east is 66 µg/m3 & on Euston Road it is 84 µg/m3.)
Camden has so far refused to entertain the two road closures I have suggested - Torrington Place and Goodge Place.
I am now going to suggest the following road closures to Camden and Westminster to make Fitzrovia "access only".
Close Goodge Street at Westminster boundary at junction with Goodge Place; close New Cavendish Street at the junction with Cleveland Street, and finally close Clipstone Street at the junction with Cleveland Street (this would also require Cleveland Street to be one-way north bound).
I believe it will not impact on access to all streets by motor vehicles for deliveries and drop-offs, etc. But it will eliminate entirely motor through traffic across the Camden/Westminster border and mitigate the effect of Gower Street northbound traffic turning into Torrington Place. This would also cut down on traffic along Grafton Way which also a victim of WEP.
