Updated Guidelines for the Design and Application of Speed

A speed bump is also a raised pavement area across a roadway. Speed bumps are typically found on private roadways and parking lots and do not tend to exhibit consistent design parameters from one installation to another. Speed bumps generally have a height of 3 to 6 inches (76 to 152 mm) with a travel length of 1 to 3 feet (0.3 to 1 m).

Speed bump Wikipedia

A speed bump is also known as a sleeping policeman in British English, Maltese English and Caribbean English, a judder bar in New Zealand English, and a lying-down policeman in Colombia, Dominican Republic, Croatia, Estonia, Slovenia and Russia.A speed bump is a bump in a roadway with heights typically ranging between 76 and 102 millimetres (3 and 4 in).

Speed Bumps vs. Speed Humps How to Choose

Say your target lane is standard width -- 12 feet or 144 inches. By choosing a four-piece speed bump (2 middle sections, 2 end caps), you can cover a 78-inch width, which is greater than the track width of a personal vehicle. Placing that 4-piece speed bump in the center of the road, leaves 33-inches of uninterrupted pavement on either side.

SPEED BUMPS AND SPEED HUMPS

Sep 22, 2006· However, as explained above, the function and design of speed bumps and speed humps makes them more appropriate for relatively low speed roads than for roads with higher speed limits. Since the majority of state highways typically carry traffic moving at speeds over 30 miles per hour, they are not usually considered appropriate for state highways.

2.2 Design of speed bump cover unit Speed bump cover is supposed to carry the vehicle load and support the impact shock from vehicle tires. Therefore, the cover had to be robust enough to endure both large static load and dynamic impact. The profile of speed bump is important since it influences the interaction between vehicle and speed bump.
