Ribbon of curvature of the basket clothoid

The basket clothoid is a sequence of design elements for the alignment of roads and railways . It consists of two clothoid pieces curved in the same direction with different parameters, which have the same radii and common tangents at the point of impact. In practice, the basket clothoids are used extremely rarely and only when cramped conditions do not allow any other possibility of routing. The guidelines restrict the use of basket clothoids, as they are problematic in terms of driving dynamics and should not be used for reasons of road safety. If use is absolutely necessary, the clothoid parameters of the successive clothoids should only differ insignificantly from one another.
