Abstract
Car flow estimation is the base to make transportation plans of the next day and car flow adjustment measures before blockage occurs. It is difficult to solve car flow estimation problem directly. The layered calculation model for railway network car flow estimation is established based on decomposition coordination method. The calculation model divides the original estimation problem into three layers. They are: the coordination layer, the decomposition layer, and the execution layer. The car flow estimation is solved from top to bottom. The coordination parameters are made to coordinate the calculation results of the decomposition layers. According to this calculation model, a pilot car flow estimation system is developed and put into practice. The result shows that the layered calculation model is an efficient method to solve railway network car flow estimation problem, and should be developed further.
