A low level traffic direction pavement marker is secured, at spaced distances with others, to early alert, inform, and guide a motorist, via contrast, emphasis, and directional position, in his or her correct vehicle maneuver in a special channelization. An elongated body less than an inch high, four inches wide, and available in lengths of 6, 8, 10, or 12 inches, of elliptical top shape, has: a planar bottom surface for receiving a bonding material; a curved top surface sloping downwardly in all directions, from a highest central portion; a surrounding continuous side surface, angled inwardly at 60 degrees, from the bottom surface, and extending to the curved top surface; a reflective material optionally positioned on this surrounding continuous side surface; a transition shoulder extending about the entire bottom surface from the planar bottom surface to the surrounding continuous side surface; and a transition shoulder extending about the entire curved top surface from the curved top surface to the surrounding continuous side surface, these shoulders being effective in protecting the reflective material; and a transversely arranged group of three straight lines having a common central crossing, presented on the highest central portion, with one line being perpendicular to a longitudinal axis, and the other two lines being at respective opposite angles from the perpendicular line, used in arranging these pavement markers to indicate either a division of driving lanes, or a change in direction to the right or left.

A low level traffic direction pavement marker to visually early alert, inform, and guide a motorist, via contrast, emphasis, and directional position, in his or her correct vehicle maneuver into special traffic lanes at many otherwise troublesome traffic areas, comprising an elongated body, less than or equal to one inch in height, of substantially elliptical shape, when viewed from above, having: (a) a planar bottom substantially elliptical surface for receiving a bonding material for securement to the pavement; (b) a curved top surface sloping downwardly in all directions from a highest central portion; and (c) a surrounding continuous side surface following a substantially elliptical path, angled inwardly at substantially sixty degrees in reference to the planar bottom, from the bottom surface and extending to the curved top surface; (d) a planar first shoulder extending about the entire surrounding continuous side surface, defining the transition from the planar bottom surface to the surrounding continuous side surface; and (e) a substantially vertical planar second shoulder extending about the entire surrounding continuous side surface, and protecting the continuous side surfaces from vehicle wheel forces defining the transition from the curved top surface to the surrounding continuous side surface.
