To make cycling safer and more inviting the Dutch built a vast network of cycle paths that are clearly marked, have smooth surfaces, separate signs and lights for cyclists, and are wide enough to allow side-by-side cycling and overtaking. At roundabouts it is the cyclist that has prority.
In many cities the paths are completely segregated from motorised traffic. Sometimes, where space is scant and both must share, you can see signs showing an image of a cyclist with a car behind accompanied by the words 'Bike Street: Cars are guests'. The schools plays a part in this too, with cycling proficiency lessons a compulsory part of the Dutch school curriculum. All schools have places to park bikes and at some schools 90% of pupils cycle to class.
We have a Health and WellBeing strategy in Lambeth thats drafted by Lambeth Council and the CCG. Transport is clearly an important issues and some of these ideas could be included as suggestions to work with Lambeth council on.
