Locating High-Speed Rail Using Ant Algorithm

The paper puts forward a method of locating high- speed rail based on remote sensing and geography information technology using ant algorithm. High-speed rail location design factors are mainly considered: the topographical condition, geomorphy, geology, hydrology, layout plan, environmental influence, engineering reliability, security, investment income and so on. The decision for these factors is the key to the railway location design optimization. In this paper, high-speed rail location system is established based on GIS technology. The design parameters are obtained by a series of analyses to the influence factors. The analyses include buffer analysis, overlay analysis, network analysis and hierarchical analysis. By adjusting the technical constraints or environmental indicators, the multi- factor, multi-parameter comprehensive quantitative evaluation system for high-speed rail location is realized. Finally the optimal railway location is obtained using ant algorithm.
