Issue
Across most of the streets in central Bath there is very low tonal contrast between the materials used for the footway and kerb edge and those used for the carriageway. This can make it difficult for people with sight loss to distinguish footway from carriageway and to read level changes which can often be unpredictable.
Opportunity
Using footway and carriageway material that provide a greater tonal contrast would make navigating easier and safer for many people with low vision. Even if similar toned materials must be used for both footway and carriageway a contrasting material is used for the the kerb would aid legibility. Applying a consistent tonal rule to that differentiates level surfaces from kerb up-stands would help people with low vision to predict if they are about to encounter a level change.
