There is a sub-group of researchers and practitioners on inclusive travel who I refer to, in my own private shorthand, as "The Iconographers." These are unusually motivated individuals who are tackling the nexus of problems associated with wayfinding, visual representation of information, databases of information on venue access, and a host of related issues.
They are behind-the-scenes and, at the same time, leading the rest of us through their diligence and innovation.
I received an inquiry this week about icons and signage representing disability,"Is there an international standard that is used in the iconography depicting people with disabilities."
Unfortunately, the answer is, "No."
Here is a link to one possible set of icons promulgated by the Graphic Artists Guild:
