This geometry combines the advantages of the widely used chlotoide and cosine transition curves. The hyperbolic transition curve is parameterized, the characteristics of the transition curve depends on the parameter, creating a continuous transition between the chlotoide and the cosine geometry.

In this paper we analyzed the possible minimal length of the transition curve based on the dynamical characteristics. We determined the relationship between the dynamical parameters and the p parameter of the transition curve. For transition curves between tangential sections and curves we compared the minimal lengths of the hyperbolic geometry to the clothoide and cosine ones. The results show that according to the considered regulations the hyperbolic geometry gives shorter transition curve length. This has significant practical consequences as it makes the design more flexible.
