Project 3-62 Guidelines for Accessible Pedestrian Signals

National Cooperative Highway Research Program (NCHRP)

Time frame
October 2001 - March 2006

  • Develop guidelines on the functional requirements and the installation of APS devices, and
  • Produce training materials that will facilitate the application of the guidelines.
  • Pedestrian crashes
  • Variation in effects attributable to age
  • Variation in effects attributable to other disabilities

  • The guidelines will explain the:
  • Functional intent of APS devices, various means of meeting this intent through tones,
  • Verbal messages, transmitted messages and/or tactile indicators,
  • Circumstances under which APS devices should be installed, and
  • Installation, positioning and orientation of APS devices for optimal use by pedestrians who have visual or visual and hearing impairment, as well as pedestrians who use wheelchairs.
