Raised Crosswalks/Speed Tables

Description
A speed table (i.e., trapezoidal shaped speed hump) designed as a pedestrian crossing. Typically implemented as a 3 inch elevated, 10 foot wide flat “table” in the center with 6 feet transition ramps on either side that are gently sloped. Has higher design speeds than those for speed humps and thus designed for streets with higher speeds and volume.


Issues Addressed

  • Speeding
  • Pedestrian safety


Applications

  • Local collectors and collectors
  • Mid-block placement
  • Appropriate for school crossings.

Advantages 

  • Effectively reduces vehicle speeds.
  • Increases crosswalk visibility & safety.
  • Volumes typically decrease where cut-through traffic is a problem.
  • Should not require parking removal.
  • Smoother on large vehiclesvthan speed humps.


Disadvantages

  • May cause increase in noise at raised crosswalk and on streets with a high volume of bus and truck traffic.
  • May cause increase in emergency vehicle response but not as much as speed humps.
  • Pedestrians may falsely assume that motorists see them and will yield.


Evaluation Considerations


Design/Installation Considerations

  • Street grade must be less than 8%
