TRB’s National Cooperative Highway Research Program (NCHRP) Web-Only Document 117B: Guidelines for Accessible Pedestrian Signals (Final Report) provides details on research used to develop a one-day training course on accessible pedestrian signals (APS) and to produce an APS intersection prioritization tool. For additional information on the training program, contact S.A. Parker of TRB at SAParker@nas.edu. A companion resource document on the training course on APS and the intersection prioritization tool was produced as NCHRP Web-Only Document 117A.
