Figure 4E-4 contains eight examples of typical pushbutton locations. For all the examples, a legend shows a horizontal black arrow labeled "Downward Slope," a black disk with a short stem labeled "Pedestrian Pushbutton," a crosshatch area labeled "Detectable Warning (per ADAAG)," and a diagonally striped area labeled "Landing Area (per ADAAG)."

The following notes are included:

This figure is not drawn to scale. These drawings are intended to describe the typical locations for pedestrian pushbutton installations. They are not intended to be a guide for the design of curb cut ramps. Figure 4E-3 shows the recommended area for pushbutton locations.

Each example shows a plan view of one corner of a 90-degree intersection of two streets, each with a sidewalk. Midway on each section of street, two sets of parallel white lines denoting crosswalks are shown, one horizontal to the left of the corner, and one vertical below the corner. On the corner radius, two curb-cut ramps are shown, one aligned with the east-west crosswalk and one aligned with the north-south crosswalk.

The first example, shown on this slide, is labeled "A – Parallel Ramps with Wide Sidewalk." It is shown with the corner denoted as a 30 ft corner radius and sidewalks as a dimension of 12 ft wide. Each sidewalk ramp leading to a crosswalk is shown with a horizontal black arrow on either side of it pointing to the center of the ramp, denoting a downward slope. The pedestrian pushbutton symbol is shown to the outside of each ramp and close to the street. A narrow strip of the ramp at the street edge is marked with crosshatching, denoting an area of detectable warning (truncated domes).

The second example on this slide is labeled "B – Parallel Ramps with Narrow Sidewalk." It is shown with the corner denoted as a 30 ft corner radius and sidewalks as a dimension of 5 ft wide. Each level area leading to a crosswalk is shown with a horizontal black arrow on either side of it pointing to the center of the area, denoting a downward slope of the sidewalk to a relatively level turning space at the crosswalk. The pedestrian pushbutton symbol is shown at the end of each landing away from the street. A narrow strip of the ramp at the street edge is marked with crosshatching, denoting an area of detectable warning.
