The Transportation Research Board (TRB) has published a guidebook on airport wayfinding for people who are elderly or have a disability under its Airport Cooperative Research Program.
The new resource, "Enhancing Airport Wayfinding for Aging Travelers and Persons with Disabilities", offers best practices for improving and optimizing information for wayfinding and travel by people with cognitive, sensory, or mobility challenges in the complex environment of airports. It is intended to help airport operators and planners implement pedestrian wayfinding systems in standardized accessible formats to better serve travelers with disabilities or who are elderly.
The guidebook includes an airport wayfinding accessibility audit, guidance on creating wayfinding plans, information on best practices and available technologies and state-of-the-art techniques for wayfinding, and other topics. Further information is available on TRB's website
