The influence of width of road humps on operating speed

David Daniel, Basil The influence of width of road humps on operating speed. In: Talent Management Symposium (TMS 2012) , 11-12 July 2012, Australia.



Road humps are synonymous with traffic calming seeing as this type of speed control device has the distinction of being highly effective in reducing speeds. Speed reduction brought about by road humps can be attributed to the drop in discomfort levels as vehicle speeds are lowered. Factors that influence speed choice across road humps include drivers’ perception of speed that is suitable for safe and comfortable passing, the design of road humps, and the type and condition of the vehicle. This research was aimed at determining the effect of hump width (with respect to road with) on device operating speed of 100 mm Watts profile road humps with fixed length of 3.7 m. It was found that smaller hump width to road width (WH/WR) ratios produced lower device operating speeds, and that the use of smaller hump widths is more viable for wide roads (10 m or greater in width).
