Accessible Pedestrian Signals (APS)

Accessible Pedestrian Signals (APS) are traffic signal system devices which combine a pedestrian detector – commonly a pushbutton – with pedestrian signal indications in non-visual formats. These non-visual indications are both audible and tactile.

APS Speech Messages
WSDOT requires that all APS units include speech messages. In order to provide a consistent message throughout the state, speech messages must follow the APS Sample Message Table (pdf 456 kb), which is to be used in concurrence with General Special Provision (GSP) 8-20.2(9-29.19).OPT1.FR8.
