Travelers who are blind or visually impaired use a variety of cues and strategies to orient themselves within their surroundings and move through space to where they want to go. This wayfinding process can be particularly challenging in complex urban environments where some cues, such as detectable edge treatments, the sound of surging parallel traffic, or other indicators may be inconsistent, confusing, misleading, or missing.

TCRP Research Report 248: Tactile Wayfinding in Transportation Settings for Travelers Who Are Blind or Visually Impaired, from TRB's Transit Cooperative Research Program, seeks to help provide consistency of tactile walking surface indicators and guidelines for their use in multimodal environments.
