Module E1 - Slide 17
The third example, shown on this slide, is labeled "C – Parallel Ramps with Narrow Sidewalk and Tight Corner Radius." It is shown with the corner denoted as a 10 ft corner radius and sidewalks as a dimension of 5 ft wide. Each sidewalk level landing leading to a crosswalk is shown with a horizontal black arrow on either side of it pointing to the center of the level landing or turning space, denoting a downward slope of the sidewalk. The pedestrian pushbutton symbol is shown at the end of each level landing away from the street. A narrow strip of the landing at the street edge is marked with crosshatching, denoting an area of detectable warning.
The fourth example is labeled "D – Perpendicular Ramps with Crosswalks Far Apart." It is shown with the corner denoted as a 30 ft corner radius and sidewalks as a dimension of 12 ft wide. The crosswalks are shown slightly farther away from the corner. Each sidewalk ramp leading to a crosswalk is shown with a vertical black arrow centered on each ramp and pointing toward the street, denoting a downward slope. At the top of the ramp, an area is shown marked with diagonal stripes, denoting a landing or turning space. The pedestrian pushbutton symbol is shown on the outside of each ramp at the point where the landing ends and the downward slope begins. A narrow strip of the ramp at the street edge is marked with crosshatching, denoting an area of detectable warning.
