TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 150: Accessible Pedestrian Signals: A Guide to Best Practices (Workshop Edition 2010) provides an introduction to accessible pedestrian signals (APS) and highlights issues related to the design, installation, operation, and maintenance of APS.
The report also addresses public education, U.S. case studies, and international practice related to APS. In addition, the report explores issues related to travel by pedestrians who are blind or who have low vision, and examines traffic signals and modern intersection design.
NCHRP Web-Only Document 150 is designed to serve as a companion resource document to a one-day training course on accessible pedestrian signals. For information on the training program, contact Stephan Parker
of TRB at SAParker@nas.edu.
NCHRP Web-Only Document 150 is a reformatted edition of and replaces NCHRP Web-Only Document 117A
: Accessible Pedestrian Signals: A Guide to Best Practice.
On July 20, 2011, TRB co-sponsored a web briefing or "webinar" that explored information about the project. As a part of the webinar, panelists provided information about how to host a free APS workshop offered through NCHRP. Details about the webinar can be found on our website
