Research on Calculation Method of Line Carrying Capacity for Urban Rail Transit
摘要
Abstract
Based on the analysis of existing calculation method of line carrying capacity for urban rail transit,a new calculation thinking of line carrying capacity for urban rail transit was proposed with references to the calculation method of train tracking interval.Namely,by virtualizing the train's dwelling operation at a station into the process of the train's uninterrupted operation in a long-distance block section,the train tracking interval under fixed block and moving block was solved respectively.The proposed method could eliminate the influence of the train dwelling operation on the calculation of train tracking interval,and it was only necessary to calculate the train tracking interval in section to determine line carrying capacity.Moreover,the problem of fast train overtaking slow train for urban rail transit under express/slow operation mode was analyzed through the virtualization processing method,and the method for determining the location of overtaking station was given,based on which the line carrying capacity under express/slow operation mode was calculated.The feasibility of the calculation model was verified by a practical case.关键词
