Abstract A directing barrier for a roadway has a driving surface which rises from the roadway edge outwardly first gently and then more strongly and then spaced below an overhanging guiding mechanism. A steep, convex rise follows the gentle rise and transfers under the guiding mechanism into a flattened area.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
In a safety barrier adapted to be placed adjacent a roadway having an upper surface, said safety barrier having means defining a driving surface thereon which extends generally upwardly and outwardly from a lateral edge of said roadway surface and includes a first portion which is adjacent said lateral edge of said roadway surface and rises gently, and wherein said saftey barrier has a guide portion spaced vertically above and overhanging at least part of said driving surface, the improvement comprising wherein said driving surface includes second and third portions in addition to said first portion, said second portion being between and contiguous with said first and third portions and merging smoothly therewith, wherein said second portion of said driving surface rises steeply and includes a generally concave region followed by a generally convex region, wherein said third portion of said driving surface is approximately flat and rises gently, and wherein said guide portion overhangs said third portion of said driving surface.
