technical field [0001] The invention relates to the technical field of high-speed railway transportation capacity calculation, in particular to a high-speed railway section passing capacity simulation calculation system. Background technique [0002] China's high-speed railway has developed rapidly in the past ten years. The transportation capacity of high-speed railway is one of the important concepts to ensure the efficient operation of high-speed railway. How to quickly and accurately calculate the capacity and conduct simulation verification analysis has become a difficult problem. Most of the calculation methods of the passing capacity of high-speed railway sections are derived from the calculation methods of the passing capacity of the existing lines. The deduction coefficient method, the compression and encryption algorithm of the train operation map and other methods are more feasible, but they require a large number of assumptions to simplify, and do not consider the...
