Abstract:Research purposes : To define the influential content of the operating environment of high - speed railway, and estimate its operating environment cost,on the basis of calculation content of t!ie operating environment of high - speed railway, the cost - significant ( CS) theory and neural network method were put forward to predict the environmental costs of proposed operating projects in this paper. Meanwhile, Changsha - Yiyang inter - city railway environmental costs prediction results proved the applicability and accuracy of t!ie model. Research conclusions:( 1) Use the cost - significant ( CS) theory to confirm cost - significant items of high - speed railway,and then it can simplify the workload of environment cost estimation. (2) Neural network method has applicability in high - speed railway operating environment cost estimation. ( 3 ) High - speed railway operating cost database need to be supplemented further in order to improve accurate estimation. (4) The nonlinear estimation methods of high - speed railway which suggested in this paper,can be applied in operating environment cost estimation.
