根据既有繁忙干线客货混运的运输组织模式和运营特征,利用已有通过能力计算方法,确定研究原则,对时段性和计算区段概念进行界定,通过列车间隔时间和不同种类列车越行等分析,采用修正的负指数分布模型,提出既有繁忙干线时段性通过能力的规划模型和计算方法,并以沪宁线列车运行图某段上行区间为例进行验证。计算结果表明:4个时段的通过能力理论值分别为53、26、49、43列,符合每个时段繁忙干线运营实际,模型与算法可行。
According to the transport organization mode and operational characteristics of both passenger and freight mixed traffic on existing busy trunk lines, the existing methods of calculating capacity are used to determine the principle of study and the concepts of timeliness and calculation section are defined. Through train time intervals and different types of trains, , The modified negative exponential distribution model is used to propose the planning model and calculation method for the capacity of existing busy trunks and to verify the uplink section of a section of the train operation diagram of Shanghai-Nanjing line. The calculation results show that the theoretical values of passing capacity of the four periods are respectively 53, 26, 49 and 43 columns, which are in line with the practical operation of the busy trunk at each time. The model and the algorithm are feasible.
