DESIGN OF TRAIN OPERATION SIMULATION SYSTEM BASED ON "LAYER " MODEL

The “layer” model is introduced into train operation simulation to develop a train operation simulation system (TOSS) ，which can be used for different locomotives, running parameters and lines. The virtual “layer” model can simulate any longdistance line on a limited track. The line models of different lines and stations can be constructed in the TOSS model definition. The system converts the actual line into the “layer” model, simulates the train operation on the line through the annular track model, and stores the operation-state parameters with the “layer” model structure. TOSS can statistically analyze the data generated through the data analysis subsystem and restore the whole train-operation process by various animation demonstration. The application of “layer” model is the core of TOSS, which can realize the train operation simulation intuitively, and provide decisions basis for route planning, station docking or train operation scheduling scheme
