One of the proposals in your draft Air Quality Strategy is to put in place 'special measures for the highest pollution days ... .likely to involve traffic management and potential diversions. If necessary ... wider measures to reduce traffic levels'. When and where do you anticipate these measures being introduced? As the highest levels are mainly on key arterial routes, do you anticipate closing Marylebone or Brixton Roads? How will you predict the highest pollutions days and inform drivers?

Policy 6 of the draft Mayor's Air Quality Strategy states we will develop a series of measures with boroughs and other stakeholders to help reduce and manage air quality on days where we exceed daily mean EU limit values for PM10. This Policy is intended to tackle the worst exceedences where they happen. Exceedence days can occur in multi-day periods know as episodes. Episodes can be caused by a number of complicated factors such as emissions from within and outside London, weather and geography. Localised action during such episodes will help meet EU limit values.

Measures will include traffic management and information provision during pollution episodes, as well as events to promote walking and cycling and the urban realm. For measures focused on highest pollution days, the exact triggers are still being determined, and this will require input from London Boroughs.

As for the exact measures themselves, our assessments are not completed and it would be premature to be more specific at this stage. As part of this work we are exploring how to inform Londoners of measures undertaken.
