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.
