Modelling of Curvature of the Railway Track Geometrical Layout Using Particle Swarm Optimization

Katarzyna Małgorzata Palikowska

Abstract


A method of railway track geometrical layout design, based on an application of cubic C-Bezier curves for describing the layout curvature is presented in the article. The control points of a cubic C-Bezier curve are obtained in an optimization process carried out using Particle Swarm Optimization algorithm. The optimization criteria are based on the evaluation of the dynamic interactions and satisfaction of geometrical design requirements.

Keywords


Particle Swarm Optimization algorithm, cubic C-Bezier curve, curvature of the railway track layout, dynamic interactions, transition curve
