Research on the Equilibrium of Train Diagram Based on Big Data

Taking the expectation and variance in adjacent time intervals, the mean value and variance of time intervals as the calculation indexes, the distribution and orderly balance of arrival time intervals of stations are described. Finally, the equilibrium indexes matrix and the equilibrium index vector is used to evaluate the balance between the train and the map. The results show that the distribution of the train arriving distribution is better than that of the train departure; the distribution of Changsha South Railway Station maps has a poor distribution interval; the equilibrium of the Hengshan west Station, Zhuzhou West Station, and Changsha South Station is poor and should be combined with the train. In the late days, the optimization of the operation chart structure was taken into consideration. There is a big difference in the equilibrium between the diagram and the actual arrival and departure of the Zhangzhou West, Leiyang West, Hengshan West and Zhuzhou West station.
