基于STP数据及改进UIC 406的编组站出发场能力计算方法研究OA北大核心

UIC 406 is a calculation method used to determine the carrying capacities of railway stations and sections by compressing the time interval between trains while ensuring traffic safety.This method has been widely utilized to calculate the peak-hour carrying capacities of intermediate stations and sections.The traditional UIC 406 method cannot be directly employed to calculate the peak-hour carrying capacity of the marshalling station because its carrying capacity is affected by various factors including the use of locomotives and vehicles,as well as operational connections.Given the above problems,the departure yard of marshalling station was selected as the research object,and operational processes were analyzed based on data collected by the shunting train protection(STP)system.Subsequently,the paper proposed an improved UIC 406 method suitable for calculating the carrying capacity of the departure yard in marshalling station.With the improved method,it calculated historical operational data from the up-direction departure yard of a marshalling station as an example.The results indicate that the improved UIC 406 method is feasible and effective.The improved method can also overcome the deficiency that it is relatively difficult to collect data in traditional assessment methods.This improved method enables the convenient calculation and evaluation of the departure yard's carrying capacity.
