Because of these counter-productive responses, speed bumps traversals of at least 2 m (about 5 ft.) with smooth approach and exit should be used wherever possible. Speed bumps vary in length, but it is typical to leave space between the bump and either edge of an enclosed road (i.e. with curbs and gutters) to allow for drainage.
A curb extension (or also neckdown, kerb extension, bulb-out, bump-out, kerb build-out, nib, elephant ear, curb bulge, curb bulb, or blister) is a traffic calming measure which widens the sidewalk for a short distance. This reduces the crossing distance and allows pedestrians and drivers to see each other when parked vehicles would otherwise ...
An Actibump is an automatic speed-bump on a road. It is a product developed by the Edeva AB group, a Swedish traffic systems manufacturing company. It is triggered when a speeding vehicle drives over an activated piece of the road, causing a change in the level of the road as a warning to the driver. [1]

A major issue with the profilers has to do with their contact areas compared to the footprint of a tyre. The latter is much larger than any of the static/slow speed Class 1 profilers or a typical laser profilometer. This can be addressed with a 4-inch or 6-inch line laser mounted in the wheelpaths to mimic the tire patch width.
Traffic engineers refer to three "E's" when discussing traffic calming: engineering, (community) education, and (police) enforcement.Because neighborhood traffic management studies have shown that residents often contribute to the perceived speeding problem within their neighborhoods, instructions on traffic calming (for example in Hass-Klau et al., 1992 [4]) stress that the most effective ...
