The speed table is designed with a flat top and brick or any other textured materials are used for contruction. The brick or textured material helps improve the aesthetics of the speed tables, which in turn makes them highly visible and reduces speed and enhances safety. The flat section of a speed table can be long enough for the whole wheelbase of a passenger vehicle to rest on. The long flat field also allows for the speed table to provide a higher design speed as compared to speed humps.

Speed tables are recommended for areas where a low speed is desired and a relatively smooth ride is necessary for larger vehicles.

  

Advantages:

• Effective for reducing speeds, although not as much as that of a Speed Hump
• Provide a smoother ride for larger vehicles (such as a fire truck) than the Speed Humps

Disadvantages:

• May lead to an increase in air pollution and noise
• If textured materials are used for construction, the speed table may be expensive
• If textured materials are not used, the speed table may have questionable aesthetics

Effectiveness:

• For a 6.7 meter speed table:
• An average decrease of 6.7 to 3.7 accidents per year (or an 45% decrease), taken from 8 locations
• An reduction in speed from an average of 59 to 48 kilometers per hour (or a 18% decrease), taken from 58 locations

  

Similar Measures:

• Placing a crosswalk on to the flat section, will be a Raised Crosswalk
• Raising the general level of an whole intersection, will be a Raised Intersection
• Removing the flat section in the center,will be a Speed Hump
