NOTE TO VISITORS
This site was developed several years ago. Since then, we have continued on with additional research on APS and have developed updated content which is available in a free printable document entitled "Accessible Pedestrian Signals: A Guide to Best Practices". We are working on adapting this new content to the website and hope to have the website updated by the end of 2008. The information in the current website is valid, but the updated information in the printable document contains some additional guidance, especially regarding the design and installation of APS devices.

This online guide is an interim product for NCHRP
Project 3-62, Guidelines for Accessible Pedestrian Signals,
which is being carried out under a contract with The
University of North Carolina Highway Safety Research Center
under the direction of David L. Harkey (Principal Investor).
It provides background information on how pedestrians who are
blind or visually impaired cross streets, and how Accessible
Pedestrian Signals assist this process.
The print version of the guide was prepared by J.M. Barlow, B.L. Bentzen
, Lee Tabor of Accessible
Design for the Blind. The web version was adapted from the print
document by the PBIC staff.
