A speed table is a 7-meter-long section of roadway, raised across the width of the road, causing a vertical deflection for vehicles passing over them. Unlike speed humps, a speed table has a 3-meter-long flat top section between the 2-meter-long gradual tapers. Their primary purpose is also to reduce vehicle speeds. However, their elongated design reduces the negative impacts emergency vehicles and transit buses may experience with speed humps. Speed tables are typically better suited for collector roadways.
The specific locations selected for the installation of speed tables depend on existing site conditions. Speed tables in front of driveway openings, on curves with limited visibility, or over sewer or water infrastructure covers should be avoided. Adequate spacing of other measure is also considered to achieve the desired calming effect. They have minimal impact on drainage but they require additional caution during snow clearing operations.
