"Raised crossings are a special case of speed tables. They are speed tables placed at pedestrian crossing locations. A speed table is a raised area of roadway that is intended to slow traffic. Most motorists slow to 30 - 35 km/h to traverse a speed table. Raised crossings are elevated to a height that matches the adjacent sidewalk and are flush with the curb at each end."
