All you wanted to know about bumpy pavement tiles but were afraid to ask

[Quartz]

The Poke has - unusually - a serious article on those bumpy pavement tiles and how the blind use them to help navigate.

@Dr Amy Kananagh

As I’ve been trained by fab @guidedogs how to navigate using tactile pavement I thought I would share some key info in a thread! First, blister paving at road crossing points. The tactile round bumpy paving at pelican crossings is usually red & bumps are in horizontal rows.
