Pedestrians and cyclists
A driver, pedestrian or cyclist needs enough time to react successfully if they meet one another (for example, where there is limited visibility or where other noise might mask the approach of a vehicle).
Wherever it is reasonable to do so, you should provide separate routes or pavements for pedestrians to keep them away from vehicles. The most effective way to do this is to separate pedestrian from vehicle activity, by making routes entirely separate. Where possible, pedestrian traffic routes should represent the paths people would naturally follow (often known as ‘desire lines’), to encourage people to stay on them.
