ABSTRACT:
A traffic lane delineator includes an elongate centrally disposed planar strip flanked on at least one side, and generally both sides, by outwardly extending tabs or ribs. The width of each rib may be equal to the space between adjacent ribs or the rib width and spacing therebetween may be varied if desired. This configuration provides an audible warning if a moving vehicle engages and drives upon the ribs. The planar strip preferably also includes a longitudinally extending double yellow line marking which may include reflective material. A physical barrier along the central strip may take the form of spaced-apart stanchions which may include reflective material for visibly delineating the traffic lanes. The delineator may be readily installed on a lane surface as needed as well as removed and rolled or stacked for compact storage.
