A BUMPY ROAD AHEAD?

A study was made of the effectiveness of six different speed bump configurations, ranging from 2 to 3 in. (5.08 to 7.62 cm) in height and from semicircular to trapezoidal in shape with varying widths, in reducing vehicle speeds. Determination of hazards was restricted to only the minimum hazards that could be easily and unequivocally identified. Briefly, the following conclusions were drawn: (1) the speed bumps tested are not effective in reducing vehicle speeds; (2) speed bumps present an immediate and specific hazard to some vehicles (bicycles, motorcycles, etc.) and a potential hazard to all vehicles; (3) it is impossible to design an effective, narrow speed bump for all types of vehicles; and (4) speed bumps would cause noise pollution in residential neighborhoods. Descriptions of the types of vehicles used in the study, the test methodology, and the evaluation criteria are included in this article along with a discussion of the results obtained.
