A speed cushion is a traffic calming device that is used to reduce vehicle speeds. It is typically made of rubber or concrete and is raised up to several inches above the road surface. Speed cushions are designed to be narrow enough that emergency vehicles can pass over them without slowing down, but wide enough to force cars to slow down when they drive over them. Speed cushions are often used in residential areas, near schools, and in other areas where there is a high risk of pedestrian or bicycle accidents.
Speed Cushions are available in a range of sizes with a common depth of 7’ (2.13 m), varied widths of 3’, 6’, 9’ (.91, 1.83, 2.74 m), and a height of 3” (7.6 cm). The slope of speed bumps should be between ratios of 1:10 to 1:25.
