Design of automatic block section signalling layout of appling chaos embedded particle swarm optimization algorithm based on skew tent map

Abstract

This paper analyzes the objectives and related factors in detail and presents an optimization model with two different objectives. In order to work out an efficient signalling layout scheme in combination with the practices of present railway line design, the paper discusses the steps of computer-based signalling layout optimization and the method to solve the model with the chaos embedded particle swarm optimization algorithm combined with STM (STMCPSO). Case study of signaling layout design of an existing railway line is conducted. The results demonstrate that using the STMCPSO to solve the optimization problem of signalling layout design is practicable, and this system is able to work out a satisfactory signalling layout scheme to promote the efficiency and quality of signaling layout design without any manual interference. © 2011 Springer-Verlag.
