Abstract

The paper outlines the key trends in the current science of high-speed railways layout and profile design. The employment of sophisticated laser scanning systems and satellite navigation systems simplifies the task of constructing and maintaining complex spatial curves - areas of overlapping vertical curves in the profile and transitional curves in the plan, sinusoidal or polynomial curves. As part of this research, a mathematical model has been developed to describe different transition curves with non-linear curvature and elevation characteristics of the outer rail depending on the number of zero derivatives required at the ends of the transition curves. The shape influence (character of curvature function change within the transition curve) of curvilinear sections of high-speed railway track plan on traffic dynamics is investigated. It has been found that the best dynamic performance is in the curved section of the alignment equipped with transition curves whose curvature function is represented by a 5th degree polynomial. There may also be no circular curve within the plot in question. The paper examines the construction and mutual arrangement of differently shaped curved sections and identifies their advantages and disadvantages.
