Accessible Pedestrian Signals
An estimated 85 percent of Americans living to full life expectancy will experience some sort of permanent disability sometime in their lifetime. In the U.S., the Americans With Disabilities Act has paved the way for some significant improvements for the millions of Americans who are disabled. One such improvement is the development and application of Accessible Pedestrian Signals.
An Accessible Pedestrian Signal (APS) is a device that communicates information about pedestrian timing in a non-visual format, such as audible tones, verbal messages and/or vibrating surfaces. Through the NCHRP Project 3-62 Guidelines for Accessible Pedestrian Signals, HSRC researchers are exploring how pedestrians who are blind or visually impaired cross streets, and how APS technology assists in this process.
The Center has developed an online guide containing the interim product for the project that includes information on the types of APS including audio clips, guidelines for choosing and installing and a series of U.S. case studies.
