SPEED

Tables Goal

Where traditional speed limit reduction might not be the most effective, the introduction of speed tables/raised crosswalks signify and cause driver speed reduction because of the introduction of an obstacle the driver must interact with.

WHAT IS IT?

Raised crosswalks or speed tables are similar to speed bumps in that they are both elevated a few inches above the pavement to reduce driver speed. But unlike speed bumps, they raise the whole vehicle and are flat-topped, often longer than speed bumps, and are more suitable for higher speed areas. Typically, these crosswalks are 3-3.5 inches high, 22 feet in length, and are located in areas with speed limits ranging from 25-45 mph. They can be used as a raised midblock crossing; which allows for safer pedestrian crossing in the middle of a roadway. These developments can be found near schools, parks, smaller commercial corridor sections, and other similar destinations.

Signage should accompany a raised crosswalk to warn drivers of the sudden height change, as well as to warn them to be on the lookout for pedestrians. These crosswalks should be installed in areas where there is a significant pattern of pedestrian street crossing (i.e. the middle of a block with development on both sides). Crosswalks can be designed with pavers or other distinctive materials that help define the crosswalk. Speed tables are designed to increase driver awareness of pedestrians, and make drivers slow down more than if they were approaching a speed hump.

Strategies to consider when introducing a new crosswalk include a setback to allow drivers a longer reaction/slow down time to avoid collision with a pedestrian and adding some type of reflectors or lights to increase visibility in the evening. Medians and safety islands could also be built in to create a safer crossing.
