At a location where there are blind corners, like the one above coming off a bridge which meet a path running across it, there is the potential for a near-miss or collision.
So the tendency is to install barriers as shown. These however can prove problematic to users
The woman with her children in a Christiania trike above or a mobility scooter user will have considerable difficulty and may be unable to proceed.
An alternative approach is to try to use bollards, as above, with the same problems likely to occur.
The solution below removes the risk of collision at the blind corner itself and improves sight lines giving people time and space to adapt their position or speed to avoid a collision where the rails end.
