  • Vertical deflection at entry to intersection encourages reduced vehicle speeds
  • Improves drivers’ awareness of presence of pedestrian crossings
  • Visually turns intersection into a pedestrian-oriented zone
  • Enhances access for people with ambulatory disabilities by providing level crossing
  • Encourages motorists to yield to pedestrians


  • May impact street drainage or require catch basin relocation


  • Intersections with a high volume of pedestrian crossings and low target vehicle speeds
  • Intersections with a history of pedestrian crashes or speeding issues
  • Intersections where enhancing pedestrian movement is a major goal, such as transit stops or commercial areas
  • Avoid on truck and transit routes and at other locations where speed humps and speed tables are not appropriate


  • Appropriate warning signs and roadway markings should accompany raised crosswalk
  • Use enhanced, high-visibility street materials to further draw attention to raised intersection
  • Detectable warning strips should be provided to delineate the edge between the sidewalk and the roadway. They should be red when adjoining light-colored sidewalks, such as Unpigmented Concrete, or bright white when adjoining dark-colored surfaces, such as Pigmented ConcreteAsphalt Pavers, or Bluestone
  • Use signage or other methods to alert operators of snow-clearing vehicles to the presence of raised speed reducers
  • Utilize recycled content in paving materials
  • Coordinate streetscape/utility work to minimize street cuts
