Traffic Circles can also be used in situations where it may be difficult to find locations to install speed humps or if there is a correctable accident history at an intersection within the area of concern. Multi-use lane pavement markings are installed mainly to delineate the areas of travel for motorists, bicycles, pedestrians and parked cars. Although this is the primary function of multi-use lane pavement marking, they can also provide a traffic calming element by visually narrowing the vehicle travel lane compared to an unmarked roadway. Lastly, enforcement from the police department can be an effective traffic calming strategy on a short term basis or in a targeted area.
