Abstract
A traffic guide provision is described with a twosided profile to be employed as a median barrier of roads or with a onesided profile to be employed as road edge barrier wherein the profile is provided with a substantially vertical lower side face (1), via run-up edge (2) followed by an inclined towards the outside running run-up face (3) and above a deflection strip (4) staggered towards the outside relative to the run-up edge (2) and acting upon a vehicle below the automobile body.
Claims6
A road barrier comprising:
- a rigid elongated concrete body extending along a travel lane and rising above the grade thereof to a height of about 30 cm to lie below lateral chassis portions of a vehicle traveling on said lane, said body having a vertical lower face turned toward said lane and extending upwardly from grade to an edge about 6 cm above grade, a continuously curved flank of progressively increasing steepness rising from said edge concave toward said lane and progressively receding upwardly from said lane, and a bead projecting laterally towards said lane at the top of said flank and overhanging said flank;
- and
- a strip of a material having lower friction than concrete and harder than concrete on said bead, verticals from outermost surfaces of said strip intercepting said flank substantially along the midpoint of the height thereof between said edge and said bead.
