C clothoid
The C-clothoid (also called the C-line ) is a sequence of design elements for the alignment of roads and railways . The name is derived from the C-shaped course of the axis in the site plan. The C clothoid is created when clothoids curved in the same direction collide at their origin. This gives the impression of an intermediate straight line between two circular arcs that are curved in the same direction. Due to the unfavorable lines and the resulting higher risk for traffic safety, the C clothoid should be avoided. It is better to use two flat egg clothoids .
