A curbstone in particular for a stop has a base body of a dimensionally stable material, on the upper side of which an attached part of an at least partly elastic material is fixed at least in sections. The attached part has a compressible section on at least one side; wherein the attached part, adjacent to the side with the compressible section, has at least one hollow chamber, the shape of which can be changed when the section is pressed together. As a result, the risk of damage to the bodywork is reduced by the attached part.

A raised pavement marker (RPM) is sized and configured to comply with Department of Transportation requirements and includes a main body with a top side, opposite angled side faces, opposite ends and a bottom surface structured to be bonded to a road surface. A sheet substrate is coated on a top surface with multiple layers of a photoluminescent composition containing one or more rare earth materials that emits a highly visible glowing light in dark or near dark conditions for at least 6 hours when fully charged. The sheet substrate is inserted within a recessed pocket on the top side of the RPM with the photo-luminescent top surface facing up and is covered by a transparent acrylic lens that is electronically welded to the main body to provide an integral one piece sealed structure. The opposite angled side faces may be fitted with prismatic reflective lenses.

A temporary flexible pavement marker comprising a base, a stand and a protective shield wherein at least part of the stand is reflective and the protective shield is configured to prevent materials sprayed down upon the temporary flexible pavement marker from obscuring the reflective part of the stand may be employed in the construction or repair of roads. Since the protective shield prevents asphalt from obscuring the reflective part of the stand during spraying operations there is no need for removal of a protective layer from the markers after a spraying operation.

A system comprises: a bump/dip portion that is at least one of a bump configured to project freely from a track on which a vehicle is to run and a dip configured to be depressed freely from the track, the bump/dip portion being configured to allow the vehicle to get thereover, and a bump/dip controller that controls a height difference between the bump/dip portion and the track by operating the bump/dip portion.
