The scope of this study was restricted to evaluating the potential effectiveness of various types of speed bump configurations in reducing vehicle speeds, with determination of potential liability difficulties being limited to immediate vehicle damage or driver loss of control. Based on the test data it was concluded that the speed bumps tested are not effective in reducing vehicle speed. In fact, in most of the cases that were studied, noticeability and discomfort decreased as the vehicle speed increased, so that the faster the driver went over the speed bumps, the more comfortable the ride and the less noticeable the bump. Speed bumps present an immediate and specific hazard to some vehicles, (the bicycle, the motorcycle, and the fire truck) and a potential hazard to all vehicle. It is probably impossible to design an effective narrow speed bump for all types of vehicles. Speed bumps would cause noise pollution in residential neighborhoods.
