Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
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.
Claim 2
Dependent Claim
147 words
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.
Claim 3
Dependent Claim
21 words
The barrier defined in claim 1 wherein said strip had a height of about 6 cm and a rounded upper edge.
Claim 4
Dependent Claim
28 words
The barrier defined in claim 1 wherein the average steepness between said edge and said midpoint is substantially 45° and the steepness at said midpoint is about 60°.
Claim 5
Dependent Claim
30 words
The barrier defined in claim 1, claim 2 or claim 3, further comprising an upwardly extending wall set inwardly from said impede and formed on the top of said body.
Claim 6
Dependent Claim
29 words
The barrier defined in claim 1, claim 2 or claim 3 wherein said body is symmetrical on opposite sides of a vertical median plane and forms a median barrier.
Claim 7
Dependent Claim
32 words
The barrier defined in claim 1, claim 2 or claim 3 wherein said body is asymmetrical and has a flat flank on its side opposite the side provided with said curved flank.
