Accessible Pedestrian Signal (APS) Pedestrian Pushbutton (PPB) Extension (IS-2)

This plan provides the necessary details for installing an APS PPB extension.

APS PPB extension

An APS PPB extension is only used where APS PPB cannot be made accessible by other means. Generally, this will be on existing traffic signal systems where foundations limit the ability to bring sidewalk closer to the APS PPB or locations where the APS needs to be extended over guardrail. New construction should be designed to avoid the need for APS PPB extensions.
