在论述系统动力学模型的基础上,运用其原理和方法建立了运量模型、转移运量模型、诱发运量模型和运价模型。通过模拟客运专线算例,进行了运量结果分析、运价结果分析、收入分析、运量与运价关系分析,通过定性和定量分析,论述了铁路客运专线运量、运价和收入三者之间的关系,以及相互影响因素的变化情况。 Based on the discussion of the system dynamics model, this paper establishes the traffic volume model, the transfer traffic volume model, the induced traffic volume model and the freight rate model by using the principle and method. By simulating the case of passenger dedicated line, this paper analyzes the result of the traffic volume, the result of the freight rate, the analysis of the income, the relationship between the volume of freight and the freight rate. Through qualitative and quantitative analysis, the author discusses the three modes of traffic volume, The relationship between the factors and the changes in mutual influence.
