Abstract: A tactile marker that is formed at least predominantly from a plastics material and which comprises a head portion that is arranged to sit, in use, on a walkway surface and a depending stem that is formed integrally with the head portion and is arranged in use to locate as a press fit within a hole in the walkway. The depending stem is formed along at least a portion of its length with a plurality of barbs, and each barb has a generally annular land and a generally conical portion formed integrally with the land.

Abstract: A metal-capped device in the form of a traffic surface adapter is disclosed, the device being arranged to be positioned on a localised area of a (pedestrian or vehicular) traffic surface 31 for the purpose of adapting (i.e., modifying) the characteristics of the surface. The device in one of its possible forms comprises a tactile marker having a plastics material first portion 20 incorporating a head 21 that is arranged in use to sit on the traffic surface. A depending projection 22 is formed integrally with the head and is arranged in use to locate within a recess 30 in the traffic surface and so retain the device in situ. Two or more spaced-apart apertures 26 are formed in the head, and a metal cap 27 is provided to overfit the head. The metal cap has depending tabs 37 that are shaped and positioned to project through the apertures 26 in the head and to be folded under the head to hold the metal cap captive to the head.
