摘要
结合城市轨道交通网络系统设计承载能力的概念及特点,全面系统地研究了影响城市轨道交通网络系统设计承载能力的各项因素,并在借鉴以往线路承载能力计算方法的基础上,结合约束理论(TOC),计算了单条线路的承载能力。然后根据系统线网形成的特点,利用分布估计算法建立了城市轨道交通网络系统设计承载能力的计算模型。最后,以上海市轨道交通网络系统为例,对计算模型进行验证。结果表明该模型计算量较小、计算速度较快、可行性较强,并反映了上海市轨道交通网络系统的实际情况。
By intergrading the definition and characters of the designed loading capacity （DLC） of urban rail transit network system, the factors influencing DLC are overall studied. Based on the past calculation methods, the theory of constraint is used to calculate DLC of each line. Consid- ering the formation characteristics of the system, a calculation model is built based on the estimation of distribution algorithms, which is applied to calculate DLC of urban rail transit netweok system. Finally, Shanghai rail transit network system is taken as an example to test the calculation model. The result proves that this model has smaller amount of calculation, faster speed and better practicability, and can effectively reflect the current status of Shanghai rail transit.
