WebAvoid "broken-back" curves (short tangent sections between two curves in the same direction). Use of spiral transitions, compound curves or a single longer curve is preferable because they provide some degree of continuous superelevation. When broken-back curves are necessary, there should be about 1500 feet (460 m) of tangent distance WebCompound ver tical curves (called unsymmetrical curves) consist of two parabolic arcs with a common tangent at the point of vertical intersection. The use of these curves may be required on certain occasions because of critical clearance and other controls (4,5). Sight dis tance models for unsymmetrical crest and sag curves were devel ...
