Since the passage of the Americans with Disabilities Act of 1990, transit agencies have undertaken initiatives to comply with the legislation and improve access to public transit for persons with disabilities. This report focuses on the visual aspects and issues of light emitting diode (LED) technologies designed to present external vehicle route and destination information for travelers with visual impairments. It provides key information regarding the use of LED sign technologies on transit vehicles. The report will assist transit managers and engineers in the acquisition and use of this technology to improve the dissemination of public transit information to persons with visual impairments. It includes information about system design and implementation, and offers lessons learned and recommended practices for successful deployments. The goal of this document is to summarize findings of this and previous research, and to present findings as recommended best practices for current signage methods and electronic signage technologies designed to better communicate with persons with visual impairments.
