Abstract

Wayfinding is a common task routinely performed by people traveling between unfamiliar locations, but can be a challenge for people with disabilities. In order to be able to travel safely and comfortably, people with physical disabilities depend on the accessibility of the built environment. It is through these accessibility elements that people who use wheelchairs can find their ways in unfamiliar environments. When used by people with disabilities, wayfinding and navigation services must contain accessibility data and support functions to utilize this data. However, while there are standards, such as the Americans with Disabilities Act Accessibility Guidelines, upon which accessibility data can be based or derived, currently there is no automated metric for evaluating the level of accessibility for pathways. To fill this gap, this paper proposes a Route Accessibility Index as a metric for evaluating a pathway’s accessibility and discusses its value in a wayfinding case study.
