Dynamic speed humps : a literature study (English)
Abstract [sv]

För att motverka de negativa konsekvenserna av solida farthinder, speciellt väggupp, har alternativa farthinder börjat komma, om än i begränsad omfattning. Ett alternativt farthinder kan vara utformat på olika sätt och vara antingen passivt dynamiskt eller aktivt dynamiskt. Passivt dynamiska farthinder är utformade så att tunga fordon kan passera nästan obemärkt med litet obehag medan vanliga bilister upplever liknande obehag som vid solida hinder och tvingas sänka hastigheten ordentligt. Aktivt dynamiska farthinder är däremot konstruerade så att det ska gå att hålla ett högt trafikflöde på en vägsträcka i jämn hastighet. Farthindret kräver inte att vare sig bilister eller tunga fordon saktar in under den tillåtna hastigheten för att passera obehindrat. De slutsatser som denna studie kan göra är att både passivt dynamiska och aktivt dynamiska farthinder är intressanta och kan till viss utsträckning ersätta och komplettera befintliga traditionella solida farthinder. Det är dock viktigt att påpeka att man bör vara tydlig med syftet och vilka effekter man vill åstadkomma i och med installationen av farthindret.

Abstract [en]

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.
