To mitigate the negative consequences from rigid speed humps, several alternative solutions have emerged on the market, so called dynamic speed humps. The dynamic speed humps can be classified into passive or active humps, respectively. This means that a speed hump could be either actively dynamic or passively dynamic. A passive dynamic speed hump is designed to let heavy vehicle pass almost unnoticed while light vehicles are subjected to a hump similar to a rigid speed hump and should thereby reduce their speed accordingly. An active dynamic speed hump is designed to only be active when a speeding vehicle is approaching. The intrusion on traffic flow is thereby smaller and the traffic may maintain a more even speed according to the speed limit since the hump does not affect the traffic at all as long as the speed limit is respected. The conclusions are that both passive and active dynamic speed humps are of interest and could be used as an alternative or complement to rigid speed humps. However, it is important that the purpose of the installation of the hump is clear in order to obtain the desired effect.
