Croydon’s Tories, who have opposed blanket 20mph zones, are now arguing that Croydon should learn from the apparent failure of that approach in Manchester in a contribution on Croydon Citizen.
In advance of the Croydon Debating Club debate earlier in the week (which I was not able to attend), I emailed Stuart King, the Cabinet member, to say that if I had been able to attend I would have asked his views on the Manchester experience.
This request was prompted by reading a letter from Cllr Tony Owen (Con) of Bromley Council published in the Evening Standard stating:
‘One aspect of street pollution in London that is rarely mentioned is the effect of 20mph zone, particularly in the outer suburbs. A recent review in Manchester has revealed that 20mph zones were ineffective and that £1.7m million of taxpayers’ money has been wasted.
If drivers obey the limits, vehicles will be emitting toxic fumes for 50 per cent longer at 20mph than 30mph and invariably incorporate “traffic calming”, with accelerating and braking adding further pollution.’
The second sentence gives the impression that the Manchester report gives figures on air pollution. It does not as you will see from the attached report.’

20mph Zones are part of modern road safety strategy thinking. The Councils Scrutiny Committee consider road safety issues at its meeting on 28 March. You can listen to the debate at:
