The use of road humps for moderating speeds on Urban streets
Accident Analysis & Prevention, 1992Road humps are devices placed in the path of traveling vehicles. They are used in many communities to keep a uniform and low speed on a residential street or to reduce speeds at specific locations, such as intersections or pedestrian crosswalks.

Profile Optimization of Table Top Speed Hump for Speed Control
Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011Speed bumps are the most commonly used measure to control speeding in urban areas world wide. Specifications on profiles and dimensions are largely based on road tests. Studies into speed bumps, directed at evaluating their effectiveness in reducing accidents and their environmental impact, have brought some negative aspects concerning speed bumps to ...

Humping mechanisms present in high speed welding
Science and Technology of Welding and Joining, 2006As welding speeds continually increase owing to automation and newer processes, a common defect that occurs is humping. Humping is the periodic occurrence of beadlike protuberances. The objective of the present investigation is to review current and previous researches that were made on humping, including both experimental and theoretical studies.

Optimal road hump for comfortable speed reduction
SPIE Proceedings, 2008We propose a practical tool for exploring the dynamic relation between road profiles and vehicle motion in the time domain. It is symmetric in the sense that the direct (vehicle response to a given road profile) and the inverse (ideal road profile for a given response) problems are both solved by means of digital filtering. The dynamics of each vehicle

A simple experiment to model speed bumps and humps
European Journal of Physics, 2020Abstract The effects of speed humps and bumps in slowing vehicles were investigated using a mass suspended on a spring. An impulse was applied to the mass by lowering and raising the top end of the spring by hand. The impulse duration was varied to simulate different driving speeds, and the displacement of the mass vs time was ...
