| Abstract: | The principles of developing a railway location CAD system are discussed.In the system not only the alignments of horizontal plan can be designed oramended through a man-machine interface, but also the horzontal andvertical alignments can be improved automatically by minimzing theobjective function of construction cost. The important techniques, fastgraphics animation and the derivation of objective function of constructioncost, of the system are presented in detail. |
