The Americans with Disabilities Act of 1990 has had a great impact on the implementation of Accessible Pedestrian Systems that target accessible and safety impediments faced by pedestrians with mobility and visual impairments. Intersection geometries are not uniform, and the traffic signal timing varies widely from one intersection to the next as well as days of the week and even hours of the day. The customization of the traffic signal operations is generally oriented to improving the performance of the vehicular traffic; the resulting changes in traffic patterns almost always impact the pedestrian access. Longer cycle lengths require pedestrians to cope with inclement weather or become impatient resulting in crossing without a WALK signal. For pedestrians who have vision impairments, the challenges become daunting. No longer is vision the primary means of communicating information that directly affects the safety when crossing a street.
