| Abstract: | Abstract This paper derivates the formula for computing projected mileage of transverse stations on designed routes near transition curves, through the analysis on coordinate formulas of transition curves and geometrical properties of the trans- verse stations outside the designed curves according to Design Code for Railway Route currently in effect. At the same time, the precision and convergence of the deducted formula are evaluated. This formula is proved reliable and feasible and worth popularizing by means of the trials from many strict engineering cases. |
