Module F - Slide 3


Preceding modules presented this image as an illustration of the ideal APS installation. Note that the pushbuttons poles are located at the top corner of the ramp where they are next to a level surface (for wheelchair users) but within reach of a pedestrian waiting at the curb. It is important that the signal technician or APS installer understand the goals of the installation and the functioning of the APS. Note again that there must be adequate passage room between the pushbutton and the back of the sidewalk for wheelchair users to bypass the pushbutton and the ramp if they are just continuing around the corner on the sidewalk.
