Figure 15. Curb Ramps at Marked Crossings.
Figure 15(a) Two flared-side curb ramps at each corner of the intersection. Each curb ramp is parallel to the direction of travel of pedestrians crossing the intersection. The curb ramps are in line with the marked crosswalk. An accessible route is provided through the island in the intersection.
Figure 15(b) Similar to 15(a) except the curb ramps do not extend the entire width of the cross walk. The curb ramp section and the side flares are located within the marked cross walk area on a segment of the straight curb.
Figure 15(c) Diagonal curb ramps are located at each corner of the intersection. There are flared sides on each diagonal curb ramp. The cross walks are placed so a minimum 48 inch (1220 mm) long clear space is provided at the bottom of the curb ramp inside the marked cross walk. An accessible route is provided across the island in the intersection.
Figure 15(d) Similar to 15(c) except that returned curb ramps are provided at each corner of the intersection. A minimum 48 inch (1220 mm) long clear floor space is provided at the bottom of the curb ramp within the marked crossing area. A well defined edge is provided at the side of each curb ramp.
