In Copenhagen they have timed coordinated traffic lights to give cyclists a green flow at a sensible cycling speed along main roads. It gets rid of stop start for cyclists – helps reduce cyclist/vehicle conflicts and generally makes cycling more attractive. It also standardises cycle speed. From a vehicle drivers perspective it’s ideal as it largely keeps cyclists out of the way from them. Fewer stationary cyclists. http://www.copenhagenize.com/2014/08/the-green-waves-of-copenhagen.html

How could we get this trialled ideally in Southwark?

The Walworth Road from Camberwell to Waterloo would be a great place to start.
