It is important to provide an obstacle free guideline. Street furniture which has the same volume from ground to the top is preferred. Or at least an indicator on the floor to show what’s above. To avoid temporary obstacles like bicycles, fix spaces to store them can be designed. These fixed street furniture can be used as orientation points along the natural guideline and help persons with visually impairments to orientate in the city.

People with visually impairments often use a walking stick to find their way in the city. They use the buildings or the border of the pavement as a natural guideline. Along this path there are often many obstacles, making it difficult to find a save way. For example low hanging traffic signs can cause serious headaches and benches sour legs, because with the walking stick you only feel the width of the pole and not what’s above it. This issue is more common with temporary street furniture, because they cannot be remembered.
