Description:
Speed tables provide a vertical pavement change that raises the wheelbase of a vehicle to achieve speed reductions. Speed tables incorporate a flat-topped “table” area which provides for a relatively gentle transition. The flat-topped area is sized to accommodate the most typical vehicle wheelbase (usually a passenger car), but can be extended to accommodate other vehicles if desired. Speed tables may accommodate pedestrian crossings.
Advantages:
• Potential for reduction in midblock travel speeds by between 4 and 9 mph, according to ITE.
Disadvantages:
• Causes discomfort for all drivers.
• Increases noise and air pollutions.
Suitable:
• Residential streets (midblock).
• Commercial streets (midblock).
• Mixed-use developments.
• Downtown areas.
