Common Problems Arising in the Installation of Accessible Pedestrian Signals

SUMMARY

Incorrectly aligned or located APS devices provide ambiguous information in an environment in which few other cues may be available. Careful evaluation of every pedestrian signal installation is needed to assure that it meets the goals of providing accurate and helpful information to pedestrians who have vision impairments, particularly those who may also have hearing loss. Whether APS are installed at the request of a local resident or as part of a new pedestrian signalization scheme, they must function properly if they are to be useful in communicating the information provided to sighted pedestrians by visual pedestrian signals.
