摘要
和城市轨道交通网络设计承载能力概念、特点相互结合,对影响轨道交通网络系统的设计承载能力因素进行了全面的分析,并且借鉴之前线路承载能力计算方法,和约束理论相互结合,对单条线路承载能力进行计算。之后,以系统线网形成特点,通过分布估计算法创建城市轨道交通网络系统实现承载能力计算模型的设计。最后,通过某市轨道交通网络系统为例验证计算模型。通过结果表示,此模型的计算量比较小,并且计算速度比较快,具有较强的可行性,能够将城市轨道交通网络系统的实际情况充分的反映出来。
Combining with the concept and characteristics of urban rail transit network design carrying capacity,this paper makes a comprehensive analysis of the factors affecting the design carrying capacity of rail transit network system,and combines the previous calculation method of line carrying capacity with the theory of constraints to calculate the carrying capacity of a single line.Then,according to the characteristics of the system network formation,the urban rail transit network system is established by the distribution estimation algorithm to realize the design of the carrying capacity calculation model.Finally,the calculation model is validated by an example of a city's rail transit network system.The results show that the model has a relatively small amount of calculation,a relatively fast calculation speed and a strong feasibility,which can fully reflect the actual situation of the urban rail transit network system.
